Answer:

Step-by-step explanation:

If angles C and B have equal degrees then the side AC is also equal to side AB in length and you can make their equations equal as well and solve for X.

2x+16=7x+6

get X's all on same side and the constants all on the other side,

-2x +2x+16=7x+6+-2x

The X's on the left cancel out.

16=5x+6

-6+16=5x+6+-6

add -6 to each side. On the right the 6 is now cancelled out.

10=5X

divide each side by 5 to cancel out the 5

10/5= 5X/5

2=X . ANSWER

The ratio of the price of a pair of sneakers to the price of a pair of boots is 15:19. The price of a pair of boots is 570 dolla

Genrish500 [490]

Answer:

$1470

Step-by-step explanation:

sneakers : boots

15 : 19

15 cost sneakers

------ = -------------------

19 570

using cross products

15 * 570 = 19 * sneakers

8550=19 * sneakers

divide by 19

8550/19 = sneakers

sneakers = 450

total cost = 2* sneakers + boot

total cost = 2 * 450 + 570

total cost = 900 + 570

total cost = 1470

I have a flower vase with a 6 " diameter and is 12 " tall I want to fill it 2/3 of the way full how many cubic inches will I fil

RSB [31]

Answer:

$72\pi\ in^{3}$

Step-by-step explanation:

step 1

<em>Calculate the volume of the cylinder (flower vase)</em>

The volume is equal to

$V=\pi r^{2}h$

we have

$r=6/2=3\ in$ -----> the radius is half the diameter

$h=12\ in$

substitute the values

$V=\pi (3)^{2}(12)=108\pi\ in^{3}$ ------> exact value

step 2

Calculate 2/3 of the volume

$V=(2/3)108\pi=72\pi\ in^{3}$
