Answer:

Step-by-step explanation:

m angle A and m angle C are equal sine two of those sides are equal. You would do 3x + 40 = x +50

You subtract x, leaving it to be 2x + 40 = 50

Subtract the 40, leaving it be 2x = 10

Divide both sides by 2, which leaves x = 5

and then you would do 3(5) + 40, which is 55

Can some one please help me with this math question? Please and thank you

Bond [772]

Answer:

$V = 6373.2cm^3$

Step-by-step explanation:

Given

$V = \frac{4}{3}\pi r^3$ --- Volume

$D = 23cm$ --- Diameter

Required

Find the volume

First, we calculate the radius, r

$r = \frac{1}{2}D$

Substitute 23 for D

$r = \frac{1}{2} * 23$

$r = 11.5$

Substitute 11.5 for r in $V = \frac{4}{3}\pi r^3$

$V = \frac{4}{3} * \frac{22}{7} * 11.5^3$

$V = \frac{4*22*11.5^3}{3*7}$

$V = \frac{133837}{21}$

$V = 6373.19047619$

$V = 6373.2cm^3$

Kate needs to read 2 books over summer vacation. She doesn't have the books yet so she's not sure how many pages are in each boo

Kobotan [32]

Answer:

(x+y) / 72

Step-by-step explanation:

Kate needs to read 2 books

she's not sure how many pages are in each book.

Let

Number of pages in the first book = x

Number of pages in the second book = y

Total pages of the two books = x + y

Kate's summer vacation = 72 days

she is planning to read the same number of pages each day of her summer vacation.

Number of pages she will need to read each day = (x+y) pages / 72 days

Number of pages she will need to read each day = (x+y) / 72
