Point Y is in the interior of ∠XWZ. Given that WX→ and WZ→ are are opposite rays, and m∠XWY=4(m∠YWZ) is m∠YWZ?.
EleoNora [17]

Answer:

m∠YWZ=36°

Step-by-step explanation:

Opposite rays are two rays that both start from a common point and go off in exactly opposite directions. Because of this the two rays (WX and WZ) form a single straight line through the common endpoint W.

If rays WX and WZ are opposite, then angle XWZ is straight angle. A straight angle always has the measure of 180°.

Point Y is in the interior of ∠XWZ, then angles XWY and EWZ are supplementary angles (together form straight angle XWZ). Supplementary angles always add up to 180°, then

m∠XWY+m∠YWZ=180°

You are given that

m∠XWY=4(m∠YWZ).

Substitute it into the previous equality:

4(m∠YWZ)+m\angle YWZ=180°

5(m∠YWZ)=180°

m∠YWZ=36°

Help in your answer!​
mart [117]

Answer:

Two different transformations happen. Rotation/Reflection and translation (I say rotation/reflection because they can both put the parabola where it is after being transformed)

(Rotation- 180 degrees)

(Reflection across its it's starting point)

Translation- pushed up 4 points from negative 4 to 0 on the y-axis

When you put the parent function into a graph it is positive so the u is opening upward and starts at -4. Both sides of the u go through the points (0,0)and (4,0).

But in the transformed function is negative so the u opens downward. The sides going through the points (0,-4) and (4,-4)

I hope this makes sense

Solid A has a volume of 28 in³. The scale factor of A to B is 1:2. What is the volume of Solid B?
PilotLPTM [1.2K]

Answer: 56in³

Step-by-step explanation:

Let the volume of solid B de denoted as x. Based on the information given in the question, we can solve further by:

1/2 = 28/x

Cross multiply

1 × x = 2 × 28

x = 56

Therefore, the volume of solid is 56in³.

Given the formula: d=m/V , which answer choice correctly rearranges the variables to solve for V?
77julia77 [94]

Answer:

<h2>V = m/d</h2>

Step-by-step explanation:

d = \frac{m}{V} \\Cross\:Multiply\\\\dV = m\\\\Divide\:both \:sides \:of\:the\:equation\:by\:d\\\\\frac{dV}{d} = \frac{m}{d} \\\\\\V = \frac{m}{d}

It takes Caroline 1/5 of an hour to walk a mile. Four of Caroline's friends time themselves on their own walk of different lengt
Basile [38]

Answer:

Jeanette is the friend walking at the same rate as Caroline. This is because Jeanette also takes 1/5 of an hour to walk a mile.

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

It takes Caroline 1/5 of an hour to walk a mile. Four of Caroline's friends time themselves on their own walk of different lengths. Which friend is walking at the same rate as Caroline? If:

David walked 1/2 a mile in 2/5 an hour

Jeanette walked 1/2 a mile in a 1/10 an hour

Kay walked 1/5 a mile 1/2 a hour

Mark walked 1/3 a mile in 3/5 an hour

The explanation of the answer is now given as follows:

To determine which friend is walking at the same rate as Caroline, we first convert their rate to number hours it takes to walk a mile as follows:

a. David walked 1/2 a mile in 2/5 an hour

This implies that:

(1 / 2) * 2 = 2/2 = 1 mile

(2 / 5) * 2 = 4/5 of an hour

Therefore, David takes 4/5 of an hour to walk a mile.

b. Jeanette walked 1/2 a mile in a 1/10 an hour

This implies that:

(1 / 2) * 2 = 2/2 = 1 mile

(1 / 10) * 2 = 2 / 10 = 1/5 of an hour

Therefore, Jeanette takes 1/5 of an hour to walk a mile.

c. Kay walked 1/5 a mile 1/2 a hour

This implies that:

(1 / 5) * 5 = 5/5 = 1 mile

(1 / 2) * 5 = 5 / 2 = 2.5 hours

Therefore, Kay takes 2.5 hours to walk a mile.

d. Mark walked 1/3 a mile in 3/5 an hour

This implies that:

(1 / 3) * 3 = 3/3 = 1 mile

(3 / 5) * 3 = (3 * 3) / 5 = 9 / 5 = 1.8 hours

Therefore, Kay takes 1.8 hours to walk a mile.

Conclusion.

Based on the calculations above, only Jeanette is walking at the same rate as Caroline. This is because Jeanette also takes 1/5 of an hour to walk a mile.
