Theden went on three day hike up a 40 mile trail he decided to hike 12.8 miles the first day and 16.9 miles the second day how many miles does he need to hike on the third day to finish the trail
To determine how many miles Theden needs to hike on the third day to finish the trail, we can subtract the distance he hiked on the first two days from the total trail distance:
Total trail distance = 40 miles
Distance hiked on first day = 12.8 miles
Distance hiked on second day = 16.9 miles
Total distance hiked on first two days = 12.8 + 16.9 = 29.7 miles
Distance left to hike on the third day = 40 - 29.7 = 10.3 miles
Therefore, Theden needs to hike 10.3 miles on the third day to finish the trail.

one and two-sevenths cups
one and two-fourths cups
one and one-third cups
Rana has 1 and 5/12 cups of chocolate chips left. Answer: $\boxed{\text{one and five-twelfths cups}}$.
How to find?
To find out how many cups of chocolate chips Rana has left, we need to subtract the amount she used in the cookie recipe from the amount she bought.
First, we need to convert both mixed numbers to improper fractions, so we can subtract them.
Three and three-fourths cups can be written as:
3\frac{3}{4} = \frac{(3 \times 4) + 3}{4} = \frac{12 + 3}{4} = \frac{15}{4}
Two and one-third cups can be written as:
2\frac{1}{3} = \frac{(2 \times 3) + 1}{3} = \frac{7}{3}
Now, we can subtract:
\frac{15}{4} - \frac{7}{3} = \frac{45}{12} - \frac{28}{12} = \frac{17}{12}
Therefore, Rana has 1 and 5/12 cups of chocolate chips left. Answer: $\boxed{\text{one and five-twelfths cups}}$.

Use the trapezoid shown to select all statements that are true. Select 2 correct answer(s) Question 7 options: The length of AB can be found using 3 2 + b 2 = c 2 . The length of AB can be found using 3 2 + 4 2 = c 2 . The perimeter of the trapezoid shown is 22 units. The perimeter of the trapezoid can not be found.
For the given trapezoid,
a) Length of AB is found by
b² = 3² + 4²
b) Perimeter = 30 units.
What is a trapezoid?
A trapezoid is a quadrilateral with at least one pair of parallel sides. A polygon with only one set of parallel sides is called a trapezoid. The parallel bases of a trapezoid are another name for these parallel sides. Trapezoids have two additional sides that are not parallel and are referred to as their legs. A trapezoid is a closed, four-sided form or figure that has a perimeter and covers a specific area. It is a 2D figure rather than a 3D one.
The trapezoid is given in the figure below.
a) In this trapezoid, we can draw a perpendicular from B to the line AD. Let this point be E.
So the triangle ABE will be a right triangle.
Now the hypotensue will be AB.
Using Pythagoras' theorem, we can write the following relation.
AB² = AE² + BE²
From the graph of the trapezoid, we can get
AE= 4 -1 = 3 units
BE = 7 - 3 = 4 units
So if AB =b
The length of AB can be found using the,
b² = 3² + 4²
b = 5
Therefore the given statement is false.
b) The perimeter of trapezoid = perimeter of triangle ABE + periemeter of rectangle BCDE
= 5+4+3 + 2* (5+4)
= 12 + 18 = 30 units.
Therefore for the given trapezoid, the perimeter is 30 units.

find the volume of the solid generated when the region bounded by y 9x and y =27x/x is revolved about the​ x-axis.
The volume of the solid generated when the region bounded by y = 9x and y = 27x/x is revolved around the x-axis is given by V = 27lnx - 9x + c
To calculate this volume, we need to calculate the area of the cross-section of a shell at x.
The cross-section is found by taking the difference of the two curves, y = 9x and y = 27x/x, at that particular x in the form of a rectangle.
The height of the rectangle is y₂ - y₁ and the width is the interval dx. Therefore, the area of the cross-section is given by
A(x) = (y₂ - y₁)dx = [(27x/x - 9x)dx].
The volume of the solid is then given by the formula
=> V = ∫A(x)dx.
Substituting in the expression for A(x), we have
=> V = ∫(27x/x - 9x)dx.
Integrating this expression, we get V = 27lnx - 9x + c, where c is an arbitrary constant.

Is {(-7, 20), (3, 5), (0, 5), (-2, 0), (6, -4), (-6, -9), (4, 4)} a function? Explain why
The given set of points {(-7, 20), (3, 5), (0, 5), (-2, 0), (6, -4), (-6, -9), (4, 4)} is a function since each x-value has a unique y-value.
To determine whether the given set of points is a function or not, we need to check if each input (x-value) corresponds to exactly one output (y-value).
Let's first list the x-values in the set: -7, 3, 0, -2, 6, and -6.
Now, we need to check if each of these x-values has a unique y-value. We can see that:
The point (-7, 20) has an x-value of -7 and a y-value of 20.
The point (3, 5) has an x-value of 3 and a y-value of 5.
The point (0, 5) has an x-value of 0 and a y-value of 5.
The point (-2, 0) has an x-value of -2 and a y-value of 0.
The point (6, -4) has an x-value of 6 and a y-value of -4.
The point (-6, -9) has an x-value of -6 and a y-value of -9.
The point (4, 4) has an x-value of 4 and a y-value of 4.
We can see that each of the x-values has a unique y-value. Therefore, this set of points is a function.
In fact, we can even represent this function using set-builder notation as:
{ (x, y) | x ∈ {-7, 3, 0, -2, 6, -6, 4}, y is the corresponding y-value for x }
or using a mapping notation as:
f = { (-7, 20), (3, 5), (0, 5), (-2, 0), (6, -4), (-6, -9), (4, 4) }
where f(x) is the corresponding y-value for x.

what is the correct way to measure the zone of inhibition?
The correct way to measure the zone of inhibition is to place a known amount of an antimicrobial agent on a solid medium.
What is Area?Area is a quantity that measures the size of a two-dimensional surface or shape. It is expressed in square units such as square centimetres (cm2), square metres (m2) or square kilometres (km2). Area is used to describe the size of a garden, a house, a room, a city and much more. It can also be used to calculate the amount of material required for a project, such as paint, carpet or tiles. Knowing the area of a shape can help to calculate costs, and to make sure that enough materials are ordered.
The zone of inhibition is then measured as the area surrounding the antimicrobial agent where microbial growth has been inhibited. This area is typically measured in millimeters. To accurately measure the zone of inhibition, it is important to ensure that the size of the inoculum and the amount of antimicrobial agent used remain constant. Additionally, it is important to consider the type of organism being studied, as different organisms can have different levels of susceptibility to the antimicrobial agent. Finally, the medium used should be appropriate for the organism being studied, as different media can produce different results.

The consumer price index tends to:
a. Overstate changes in the cost of living because it does not take account of quality changes
b. Overstate change in the cost of living because consumers substitute toward goods whose relative prices are declining
c. Understate change in the cost of living because consumers substitute toward goods whose relative prices are declining
d. Understate changes in the cost of living because services are excluded, whose prices tend to grow more quickly than good prices
e. Understate changes in the cost of living because the prices of volatile items such as fruit, vegetables and petrol are excluded
The correct answer is (c) Understate change in the cost of living because consumers substitute toward goods whose relative prices are declining.
consumers do substitute toward goods whose relative prices are declining. This means that they are able to maintain their standard of living even if the overall cost of living increases. Therefore, the CPI tends to understate changes in the cost of living because it does not fully account for consumer substitution.
The other options are not correct because:
a. The CPI does take into account quality changes by adjusting prices for changes in quality.
b. The CPI adjusts for changes in relative prices, so it does not overstate changes in the cost of living due to substitution effects.
d. The CPI includes services, but it may understate changes in the cost of living if the prices of services are increasing faster than the prices of goods.
e. The CPI includes a wide range of items, including volatile items such as fruit, vegetables, and petrol. However, the weights assigned to these items may change over time to reflect changes in consumer spending patterns.

The economic life cycle analysis does not take into account factors such as technological advancements or changes in regulatory requirements, which can affect the optimal replacement interval.
Yet, it is important to review and update the analysis periodically to ensure that the replacement interval remains optimal.
There are the normal steps for calculating the optimum replacement interval using the economic life cycle analysis:
1. Estimate the annual maintenance and repair costs for the item, based on historical data or industry standards.
2. Estimate the annual operating costs for the item, such as energy or fuel costs.
3. Compare the total cost of ownership for the item over its expected useful life to the cost of replacing the item with a newer or more efficient model.

Please Answer in ( a + bi ) form
Answer:
-10 - 4i
Step-by-step explanation:
We can rewrite the equation as (by getting rid of parentheses):
-8 + 3i - 2 - 7i
Now, we can add/subtract the values:
(-8-2) + (-7i+3i)
= -10 - 4i
the measure of 2 angles are (3y+11) and (11 y+15). What is the value of y if the angles are congruent
As a result, if the two angles' measurements are (3y+11) and (11y+15) and they are congruent, then y must equal -1/2.
What is angle?An angle is a geometric figure formed by two rays that have a common endpoint, called the vertex. The rays are also known as the sides or legs of the angle. Angles are typically measured in degrees, with a full circle measuring 360 degrees. Angles can also be measured in radians, which are another unit of angular measurement used in mathematics and physics. One radian is equal to the angle subtended by an arc of a circle that has a length equal to the radius of the circle. The size of an angle is determined by the amount of rotation that occurs between the two rays. This is typically measured relative to the positive x-axis, with counterclockwise rotations being considered positive and clockwise rotations being considered negative. Angles are used in a wide range of mathematical and scientific applications, including geometry, trigonometry, physics, engineering, and architecture. They are also used in many everyday situations, such as measuring the size of an opening or the angle of incidence of sunlight on a surface.
Here,
If the two angles are congruent, then they must have the same measure.
So we can set the expressions for the measures of the two angles equal to each other and solve for y:
3y + 11 = 11y + 15
Subtracting 3y from both sides:
11 = 8y + 15
Subtracting 15 from both sides:
-4 = 8y
Dividing both sides by 8:
y = -1/2
Therefore, if the measure of the two angles is (3y+11) and (11y+15) and they are congruent, then y must equal -1/2.

c
The coordinates of point bbb are \left(\dfrac{2a+7c}{9}, 0\right)left( 9 2a+7c , 0 right).
To find the coordinates of point bbb on \overline{ac}ac start overline, a, c, end overline, we need to use the formula for the division of a line segment in a given ratio. The formula is:
\begin{aligned} x &= \dfrac{x_1m+x_2n}{m+n} \\ y &= \dfrac{y_1m+y_2n}{m+n} \end{aligned}
Where m and n are the given ratio, and (x1, y1) and (x2, y2) are the coordinates of the two endpoints of the line segment.
In this case, the given ratio is \dfrac{2}{7}7 2 start fraction, 2, divided by, 7, end fraction, and the coordinates of the two endpoints are (x1, y1) = (a, 0) and (x2, y2) = (c, 0).
Plugging in the values into the formula, we get:
\begin{aligned} x &= \dfrac{a \cdot 2 + c \cdot 7}{2+7} \\ y &= \dfrac{0 \cdot 2 + 0 \cdot 7}{2+7} \end{aligned}
Simplifying the equations, we get:
