Answer:

My calculation might be wrong, so take A.

Step-by-step explanation:

Volume= Volume of hemisphere+volume of cone

Volume= $\frac{2}{3}$ ×π×r³ + πr² $\frac{h}{3}$

Volume= $\frac{2}{3}$ × $\frac{22}{7}$ ×4×4×4 + $\frac{22}{7}$ ×4×4× $\frac{14}{3}$

Volume= 134.095 + 410.6

Volume= 544.695

The perimeter of a triangle is 35 feet. One side of the triangle is five feet longer than the second side. The third side is thr

Vaselesa [24]

Given:

The perimeter of the triangle = 36 feet.

Let the three sides of the triangle be x, y and z.

The measurements of the sides of the triangle are given by

$x=5+y$ and $z=3+y$

We need to determine the length of the sides.

Value of y:

Let us determine the value of y using the perimeter formula.

$Perimeter =x+y+z$

Substituting the values, we get;

$35=5+y+y+3+y$

$35=8+3y$

$27=3y$

$9=y$

Thus, the value of y is 9 feet.

Hence, the length of the second side is 9 feet.

Length of the sides:

Length of the 1st side is given by

$x=5+y$

$x=5+9$

$x=14$

Thus, the length of the first side is 14 feet.

Length of the third side is given by

$z=3+y$

$z=3+9$

$z=12$

Thus, the length of the third side is 12 feet.

Therefore, the length of the sides of the triangle are 14 feet, 9 feet and 12 feet.

6 less than a number is 15. Let x represent the number. Which equation represents this?

qwelly [4]

**Note / Protip**
Always substitute "a number" for your variable when reading worded equations!
With that being said...

D. x - 6 = 15

Is your answer, since you are going to want to reverse it because of how the problem's worded, not c. because; c.'s worded equation would be
"A number less than six."
