If Erin had 150m/ of buttermilk and recipe require 0.25 cups of buttermilk. Erin would  have enough buttermilk for the recipe (2).

1.2. Convert the units of measurement to a common unit.

Erin has:

150 ml of buttermilk

Recipe requires 0.25 cups of buttermilk.

1 cup=  236.59 ml

So,

0.25 cups = 0.25 * 236.59 = 59.15 ml

Therefore Erin has enough buttermilk for the recipe.

1.3. The cake recipe calls for the following ingredients:

0.8 kg of flour

650 g of sugar

900,000 mg of butter

Simplify the units by converting them to a common unit

0.8 kg = 0.8 * 1000 g = 800 g

650 g = 650 g (no conversion needed)

900,000 mg = 900,000 mg / 1000 = 900 g

Therefore the required amounts of the ingredients are: 800 g of flour, 650 g of sugar, 900 g of butter.

Answer: B 102

Step-by-step explanation: The perpendicular sides of the room tells us that it is a right triangle.

To find our the area of the triangle you use the formula [tex]\frac{base*height}{2}[/tex]base*height/2

We plug in 12feet and 17 feet for the base and height

We get [tex]\frac{12*17}{2}[/tex]

12 and 2 cancel out so our new equation is 6*17 squared feet

So our answer is 102 square feet

The solutions to the trigonometric equation in this problem are given as follows:

Two angles are said to be complementary angles when the sum of their measures is of 90º.

For complementary angles, we have that the sine of one of the angles is the cosine of the other angle, hence in this problem we have that 2θ and θ are complementary angles.

Then the value of θ is obtained as follows:

2θ + θ = 90

3θ = 90

θ = 30º.

θ = π/6.

The equivalent angles, which are also solutions to the equation, are given as follows:

Step-by-step explanation:

i) 5/8  X 320 = 200 people

ii) 0.75 X 200 = 150 (people in farming but also trade). only trade = 320 - 200 = 120.

number of people in trade = 150 + 120 = 270.

b) 0.75 X 5/8 = 3/4 X 5/8 = 15/32 = 150 people (both farm and trade).

c) only farming = 0.25 X 5/8 = 1/4 X 5/8 = 5/32 = 50.

only trade = 320 - 50 (only farm) - 150 (both farm and trade) = 120.

so, only do one activity = 50 + 120 = 170.

d) traders only = 120/320 = 3/8 = 37.5%

e) P(farmer only) = 50/320 = 0.15625

I can guide you on how to perform the dilation with a scale factor of 3 for the figure.

To perform a dilation with a scale factor of 3, you would multiply the coordinates of each point of the original figure by 3. This will result in the figure being enlarged by a factor of 3.

Let's assume the coordinates of the original figure ABCDEFGH are as follows:

A: (1, 1)

B: (4, 1)

C: (4, 4)

D: (1, 4)

E: (2, 2)

F: (3, 2)

G: (3, 3)

H: (2, 3)

To obtain the image of the figure after dilation with a scale factor of 3, multiply each coordinate by 3:

A': (3, 3)

B': (12, 3)

C': (12, 12)

D': (3, 12)

E': (6, 6)

F': (9, 6)

G': (9, 9)

H': (6, 9)

These new coordinates (A', B', C', D', E', F', G', H') represent the image of figure ABCDEFGH after the dilation with a scale factor of 3. You can plot these new coordinates on a graph or use a drawing tool to visualize the enlarged figure.

Answer:

x = 6 , y = 4

Step-by-step explanation:

for the figure to be a parallelogram , the opposite sides must be congruent, that is

5y = 20 ( divide both sides by 5 )

y = 4

and

2(x + y - 1) = x + 3y ← distribute parenthesis on left side by 2

2x + 2y - 2 = x + 3y ← substitute y = 4

2x + 2(4) - 2 = x + 3(4)

2x + 8 - 2 = x + 12

2x + 6 = x + 12 ( subtract x from both sides )

x + 6 = 12 ( subtract 6 from both sides )

C=62.8

Step-by-step explanation:

1) In the formula C=πd, d represents the diameter, which is 20 inches. All you need to do is apply 20 into the equation and you get C=π20.

2) They said to use 3.14 instead of pi, so we are going to multiply 20*3.14, which is 62.8.

Let's assume David's average speed is S km/h.

A) To find David's average speed, we can use the formula: Speed = Distance / Time.

David completed the race in 5 hours, so his speed is S km/h. Therefore, we have:

S = Distance / 5

B) Ken's average speed is 9.8 km/h less than David's average speed, which means Ken's average speed is (S - 9.8) km/h.

Ken took 7 hours to complete the race, so we have:

S - 9.8 = Distance / 7

Now, we can solve the system of equations to find the values of S and Distance.

From equation (1): S = Distance / 5

Substitute this into equation (2):

Distance / 5 - 9.8 = Distance / 7

Multiply both sides of the equation by 35 to eliminate the denominators:

7 * Distance - 35 * 9.8 = 5 * Distance

7 * Distance - 343 = 5 * Distance

Subtract 5 * Distance from both sides:

2 * Distance - 343 = 0

Add 343 to both sides:

2 * Distance = 343

Divide both sides by 2:

Distance = 343 / 2 = 171.5 km

Therefore, the distance of the cycling race is 171.5 kilometers.

To find David's average speed, substitute the distance into equation (1):

S = Distance / 5 = 171.5 / 5 = 34.3 km/h

So, David's average speed was 34.3 km/h.[tex][/tex]

Answer:

A) 34.3 km/h

B) 171.5 km

Step-by-step explanation:

Since Ken's average speed is said to be 9.8km/h less than David's average speed, and we know that Ken's average speed is dependent on him traveling for 7 hours, then we have our equation to get the distance of the cycling race:

[tex]\text{Ken's Avg. Speed}=\text{David's Avg. Speed}\,-\,9.8\\\\\frac{\text{Distance}}{7}=\frac{\text{Distance}}{5}-9.8\\\\\frac{5(\text{Distance})}{7}=\text{Distance}-49\\\\5(\text{Distance})=7(\text{Distance})-343\\\\-2(\text{Distance})=-343\\\\\text{Distance}=171.5\text{ km}[/tex]

This distance for the cycling race can now be used to determine David's average speed:

[tex]\text{David's Avg. Speed}=\frac{\text{Distance}}{5}=\frac{171.5}{5}=34.3\text{ km/h}[/tex]

Therefore, David's average speed was 34.3 km/h and the distance of the cycling race was 171.5 km.

Ki traveled at an average speed of approximately 41.05 miles per hour without any stops.

To calculate the average speed at which Ki traveled from Memphis to Atlanta, we can use the formula:

Average Speed = Total Distance / Total Time

First, let's calculate the total time taken for the journey. Ki started from Memphis at 5:30 am and arrived in Atlanta at 3:00 pm, which is a total of 9.5 hours.

Next, we divide the total distance traveled, which is 391 miles, by the total time taken, which is 9.5 hours:

Average Speed = 391 miles / 9.5 hours

Calculating this, we find that Ki's average speed was approximately:

Average Speed ≈ 41.05 miles per hour

Therefore, Ki traveled at an average speed of approximately 41.05 miles per hour without any stops.

Answer:

sin∅ = √3/2

cos∅ = -1/2

Step-by-step explanation:

Notice that 14π/3 is just under 3π, so the reference angle made with the negative x-axis is π/3. Since sin(π/3) = √3/2, then sin(14π/3) is also √3/2.

cos(14π/3) works somewhat similarly. Since cos(π/3) = 0.5, and cos(14π/3) would be located in Quadrant II where the negative axis is, then cos(14π/3) = -0.5

Reema should use 3 hooks. The distance between the hooks is approximately 4 inches, and the distances of each hook from the left edge of the wood are approximately 1.75 inches, 5.75 inches, and 9.75 inches.

Given:

Wall length: 4 feet

Wood length: 28 inches

Space between hooks: about 7 or 8 inches

Minimum distance from each end: 1 3/4 inches

To center the coat rack on the wall, we need to find the remaining space on either side of the wood after accounting for the minimum distances from each end.

Convert measurements to inches:

Wall length: 4 feet = 48 inches

Calculate the available space for the wood on the wall:

Available space on each side = (Wall length - Wood length) / 2

Available space on each side = (48 inches - 28 inches) / 2

Available space on each side = 20 inches / 2

Available space on each side = 10 inches

Determine the number of hooks and the space between them:

Space between hooks: about 7 or 8 inches

Let's assume we choose a space of 8 inches between hooks for this calculation.

Remaining space for hooks = Wood length - (Minimum distance from each end × 2)

Remaining space for hooks = 28 inches - (1 3/4 inches × 2)

Remaining space for hooks = 28 inches - (3 1/2 inches)

Remaining space for hooks = 28 inches - 7/2 inches

Remaining space for hooks = 28 inches - 3.5 inches

Remaining space for hooks = 24.5 inches

Number of hooks = Remaining space for hooks / Space between hooks

Number of hooks = 24.5 inches / 8 inches (approximately)

Number of hooks ≈ 3.06 (rounded to the nearest whole number)

Since we cannot have a fraction of a hook, we'll round down to 3 hooks.

Calculate the distance between hooks:

Distance between hooks = Space between hooks / (Number of hooks - 1)

Distance between hooks = 8 inches / (3 hooks - 1)

Distance between hooks = 8 inches / 2

Distance between hooks = 4 inches

Calculate the distance of each hook from the left edge of the wood:

Hook 1 distance from the left edge = Minimum distance from each end

Hook 2 distance from the left edge = Minimum distance from each end + Distance between hooks

Hook 3 distance from the left edge = Minimum distance from each end + (Distance between hooks × 2)

Using the given minimum distance from each end of 1 3/4 inches (or 1.75 inches), we can calculate the distances for each hook:

Hook 1 distance from the left edge = 1.75 inches

Hook 2 distance from the left edge = 1.75 inches + 4 inches

Hook 2 distance from the left edge = 5.75 inches

Hook 3 distance from the left edge = 1.75 inches + (4 inches × 2)

Hook 3 distance from the left edge = 9.75 inches

So, Reema should use 3 hooks. The distance between the hooks is approximately 4 inches, and the distances of each hook from the left edge of the wood are approximately 1.75 inches, 5.75 inches, and 9.75 inches.

where [tex]A[/tex] is the area of the prism's hexagonal faces, [tex]P[/tex] is the perimeter of the hexagonal faces, and [tex]h[/tex] is the prism's height.

We can solve for the area of the hexagonal faces by splitting it into 6 triangles and multiplying the area of each triangle by 6.

[tex]A = 6\left(\dfrac{1}{2} bh\right)[/tex]

where [tex]b[/tex] is the triangle's base and [tex]h[/tex] is the triangle's height.

[tex]A = 6\left(\dfrac{1}{2}\cdot 4 \cdot 3.5\right)[/tex]

[tex]A = 6\left(2 \cdot 3.5\right)[/tex]

[tex]A = 12 \cdot 3.5[/tex]

[tex]A = 42\text{ cm}^2[/tex]

To simplify the expression √3 * √5 * √12, you can combine the square roots and simplify the numbers under the radicals.

Step 1: Simplify the numbers under the radicals:

√3 = √(3) (The square root of 3 cannot be simplified further because 3 is a prime number.)

√5 = √(5) (The square root of 5 cannot be simplified further because 5 is a prime number.)

√12 = √(4 * 3) (The number 12 can be expressed as the product of 4 and 3, and the square root of 4 simplifies to 2.)

√12 = 2√(3)

Step 2: Combine the simplified square roots:

√3 * √5 * √12 = √(3) * √(5) * 2√(3)

Step 3: Apply the rule of multiplying square roots:

√(3) * √(5) = √(3 * 5) = √15

Step 4: Substitute the simplified square roots back into the expression:

√3 * √5 * √12 = √15 * 2√(3)

Step 5: Simplify the expression further:

√15 * 2√(3) = 2√(15) * √(3) = 2√(15 * 3) = 2√(45)

Step 6: Simplify the number under the square root:

2√(45) = 2√(9 * 5) = 2√(9) * √(5) = 2 * 3 * √(5) = 6√(5)

Therefore, the simplified form of √3 * √5 * √12 is 6√5.
