Step-by-step explanation: In the figure shown, <UVW is a straight angle.

This means it measures 180 degrees.

So to find <YVZ, we add up all the angles and subtract the sum

from 180 to get the answer to this problem.

43 + 52 + 38 gives us a sum of 133.

Now we take 180 - 133 yo get 47.

So m<YVZ is 47 degrees.

Answer:

$\boxed{Option \ 4}$

Step-by-step explanation:

∠YVZ = 180 - 52 - 43 - 38 (Angles on a straight line add up to 180 degrees so if we try to find an unknown angle on the straight line, we need too subtract all the other angles from 180 degrees)

=> ∠YUZ = 47 degrees

Randi has a party-sized sandwich that is 3/4 yard long. She will cut it into smaller sandwiches that are each 1/12 yard long. Wh

Answer:

The expression for number of sandwiches is $n=\frac{3}{4}\div\frac{1}{12}$

9 small sandwiches can be made.

Step-by-step explanation:

Given:

Length of party-sized sandwich (l) = 3/4 yard

Length of each small sandwich (s) = 1/12 yard

Now, let the total number of small sandwiches be 'n'.

Now, sum of all the lengths of small sandwiches will be equal to the length of the party-sized sandwiches.

Therefore, framing in equation form, we have:

Length of large sandwich = Length of small sandwich × Total number of small sandwiches.

$l=s\times n\\\\n=\dfrac{l}{s}$

Now, plug in the given values and solve for 'n'. This gives,

$n=\frac{3}{4}\div \frac{1}{12}\\\\n=\frac{3}{4}\times \frac{12}{1}\\\\n=\frac{36}{4}=9$

Therefore, 9 small sandwiches can be made.

PLEASE HELP! Which of the following functions are the inverse of p(x)= √5x+7 ?

Rasek [7]

Answer: B

Step-by-step explanation:

You are given the function

p(x) = √5x+7

Let p(x) = y then,

Y = √5x+7

To find the inverse of a function, you need to interchange x and y and make y the subject of formula. That is,

X = √5y+7

Square both sides

X^2 = 5y + 7

Make y the subject of formula

5y = x^2 - 7

Y = ( x^2 - 7 ) / 5

the correct answer is B
