The formula for the volume of a cone is V = πr²h ÷3

You are solving for the height, h.

V = 338 cm³ and r = 6 cm

338 = π(6)²h÷3

338 = π36h÷3

338 = π12h

28.16 = πh

8.965 = h

The height of the cone is around 9 cm.

Given the equation -2x + 8y = 24, determine the x- and y-intercepts. PLZ HELP???

attashe74 [19]

Answer:

$x=(-12,0)$

$y=(0,3)$

Step-by-step explanation:

x-intercept

$-2(x-4y)=24$

$x-4y=-\frac{24}{2}$

$x-4y=-12$

$x=4y-12$

$x=4(0)-12$

$x=-12$

y-intercept

$-2(x-4y)=24$

$x-4y=-\frac{24}{2}$

$x-4y=-12$

$-4y=-12-x$

$y=-\frac{-12-x}{4}$

$y=-\frac{-12-(0)}{4}$

$y=\frac{12}{4}$

$y=3$

What is the following sum4/5+2/5

Amiraneli [1.4K]

Answer:

6/5 or 1 1/5

Edit:

soo

$4\sqrt{5} + 2\sqrt{5}$ = $6\sqrt{5}$

since they both are being multipled to the square root of 5, you can just add them (i think)

Step-by-step explanation:

6 times the square root of 5

you add 4 and 2

The length of a rectangle is 3 more inches than the width. Find the length and width of the rectangle is the perimeter of the re

n200080 [17]

Part A:

Let the width of the rectangle be = x inches

As given, the length of a rectangle is 3 more inches than the width so let the length of the rectangle be = x+3 inches

Perimeter is given as = 54 inches

Perimeter = $2(l+b)$

Equation becomes:

$2(x+3+x)$ =54

$2(2x+3)=54$

Part B:

Solving the equation we get

$4x+6=54$

$4x=54-6$

$4x=48$

$x=12$

Hence, the width of the rectangle is 12 inches

Length = x+3 = 12+3 = 15 inches

Hence, length of the rectangle is 15 inches.
