Answer:

X = 1 week

Each will have $ 26 in 1 week

Step-by-step explanation:

Tamar: y = 15x + 11

Sister: y = 7x + 19

15x + 11 = 7x + 19

15x - 7x = 19 - 11

8x = 8

x = 8/8

15(1) + 11 = 26

BRAINLIEST to wherever gets this correct

Answer:

$300\pi$ cubic feet

Step-by-step explanation:

Let r be the radius of cone and h be the height of cone.

Radius of cylinder=r

Height of cylinder=h

Volume of cone= $100\pi ft^3$

We have to find the volume of cylinder.

We know that

Volume of cone= $\frac{1}{3}\pi r^2 h$

$100\pi=\frac{1}{3}\pi r^2 h$

$r^2 h=300$

Volume of cylinder= $\pi r^2 h$

Using the formula

Volume of cylinder= $\pi (300)=300\pi ft^3$

Hence, the volume of cylinder= $300\pi$ cubic feet

5/7 = -x/8<br><br> i dont undstant this, if someone could help me it would be greatly apprecaited

irinina [24]

You can use cross-products to solve this problem. For instance, this expression would be written as 5(8)= 7(-x), or 40= -7x. What you'd do then is simplify the expression by dividing both sides of the equation by the coefficient of x, such that you'd isolate x and have the value of x.
