how to find the acute angle of each angle in a triangle if the given angles are in the form of an equation

Answer:

2 < x < 12

Step-by-step explanation:

given 2 sides of a triangle then the third side x is in the interval

difference of 2 sides < x < sum of 2 sides , that is

7 - 5 < x < 7 + 5

2 < x < 12

third side could be 3, 4, 5, 6, 7, 8, 9, 10, 11

The end behavior will be as x approaches infinity, and negative infinity, f(x) approaches infinity.

Function is a type of relation, or rule, that maps one input to specific single output.

The function f(x) is defined as:

→ f(x)= 80x* 2 + 640 - 400x - 52

We need the degree and the leading coefficient to determine the behavior.

Since our leading coefficients has a leading even degree of 5, and a positive number,

The function will Rises to the left and falls to the right.

The end behavior will be as x approaches infinity, and negative infinity, f(x) approaches infinity.

We can see that:

Part A: 3 appointments

Part B: 5 appointments

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.

Part A

Let x = number of dog grooming appointments Macy had in one day.

Given information:

Charge per appointment = $60

Total amount earned = $220

Total amount of tips earned = $40

Create an equation with the given information:

⇒ 60x + 40 = 220

Solving the equation:

Subtracting 40 from bothsides, we have:

⇒ 60x + 40 - 40 = 220 - 40

⇒ 60x = 180

⇒ 60x ÷ 60 = 180 ÷ 60

⇒ x = 3 appointments.

Part B

Let x = number of dog grooming appointments Logan had.

Given information:

Charge per appointment = $70

Total amount earned = $300

Total amount of tips earned = $50

Rental fee per appointment = $20

Create an equation with the given information:

⇒ 70x - 20x + 50 = 300

Solve the equation:

⇒ 50x + 50 = 300

⇒ 50x + 50 - 50 = 300 - 50

⇒ 50x = 250

⇒ 50x ÷ 50 = 250 ÷ 50

⇒ x = 5 appointments.

Answer: that realy saadddddddddd

Step-by-step explanation:  4xx 6y 9x

Answer: The slope is -1/5

Part A:

We want to see how often the number 4 comes up when we roll a fair dice 100 times. We will use a dice with numbers 1,2,3,4,5,6. We will keep track of how many times 4 comes up and we think it should be around 16 times because there are 6 numbers on the dice.

Part B:

We rolled the dice 100 times and got 4 32 times.

-We want to know if that is normal or if something is wrong with the dice.

-We use special numbers to check if this is normal, it's called the confidence interval

-The confidence interval tells us if 32 times is normal or not.

Part C:

The confidence interval tells us that 32 times is not normal, it's unlikely that it happened by chance. So, the dice might not be fair.

Amber and Jeica go out for lunch. Amber’ lunch cot $11. 70, and he tip 18%. Jeica’ lunch cot $12. 30, and he tip 15%, then the percentage of tip is = 33.9%

Define Percentage :

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means.

Given that the Amber’ lunch cot is $11.70.

There is a 18% tax.

Therefore the tax on $11.70 is,

= $11.70×18%

= $2.106

The Amber’ lunch cot with tax is $(11.70 + 2.106)

= $13.806.

The Jeica’ lunch cot is $12.30.

There is a 15% tax.

Therefore the tax on $12.30 is,

= $12.30×15%

= $1.845

The Amber’ lunch cot with tax is $(12.30 + 1.845)

= $14.145.

The tip that is given is $(14.145 - 13.806)

= $0.339

The percentage of tip is

= $0.339 * 100

= 33.9%

Therefore,

Amber and Jeica go out for lunch. Amber’ lunch cot $11. 70, and he tip 18%. Jeica’ lunch cot $12. 30, and he tip 15%, then the percentage of tip is = 33.9%

Answer: We know that Tonia eats 2 meals each day, breakfast and dinner. We also know that the total calories for each breakfast are 500.

If Tonia ate breakfast for 5 days, the total calories for breakfast would be 500 x 5 = 2500 calories.

We know that the total calories she ate for 5 days was 9000 and the number of calories for breakfast is 2500.

The number of calories for dinner over 5 days is 9000 - 2500 = 6500 calories.

To find the average number of calories Tonia consumed for dinner each day over the 5 days, we need to divide the total number of calories for dinner by the number of days:

average number of calories = 6500 / 5 = 1300 calories per day.

So Tonia consumed an average of 1300 calories per day for dinner over the 5 days.

If this area is expanding that mean Ac and r are a function of time and the speed is dA/dt and dr/dt can be found from the equation of the area

Then:

Ac = π×r²

dA/dt  = 2×π×r×dr/dt

According to the problem statement

dA/dt = 2×dr/dt

The rectangle has a length of 222 feet and a width of 150 feet.

A quadrilateral with parallel sides equal to one another and four equal vertices is known as a rectangle. It is also known as an equiangular quadrilateral for this reason.

Rectangles can also be referred to as parallelograms since their opposite sides are equal and parallel.

We know that the perimeter of a rectangle is the sum of all four sides. So in this case:

Perimeter = 2(length) + 2(width)

Given that the perimeter is 446 feet, we can set up the equation:

446 = 2(13x-1) + 2(9x+4)

On Simplifying, we get:

446 = 44x + 6

Now we can solve for x by subtracting 6 from both sides:

440 = 44x

Finally, dividing both sides by 44:

x = 10 feet

Now that we know the value of x, we can substitute it back into the expressions for the length and width:

Length = (13x-1) = (13(10)-1) = 129 feet

Width = (9x+4) = (9(10)+4) = 94 feet

Therefore, the rectangle has a length of 129 feet and a width of 94 feet.

An ordered pair is a set of two values, (x,y), that represents a point on a coordinate plane. To solve an ordered pair means to find the coordinates (x,y) of a point on a coordinate plane.

To solve two ordered pairs, you would need to know the coordinates of both points, and then you can graph them on a coordinate plane to visualize the relationship between the two points.

For example, if you have the ordered pairs (2,3) and (4,5), you can graph them on a coordinate plane with the x-axis and y-axis, where x represents the horizontal position and y represents the vertical position. The point (2,3) would be located at 2 on the x-axis and 3 on the y-axis, and the point (4,5) would be located at 4 on the x-axis and 5 on the y-axis.

Once you have plotted the points on a coordinate plane, you can use them to make a conclusion about the relationship between the two points, for example if they are in the same line, if the distance between them, if they form a slope, etc.
