What is the value of m in the equation 1/2m -3/4 n=16,when n =8?
maks197457 [2]
Hi,

Equation;

n = 8 \\ \frac{1}{2} m - \frac{3}{4} n = 16

Variable n is given so no need to write it down. Instead use 8.

Solving:

\frac{1}{2} m - \frac{3}{4} 8 = 16 \\ \frac{1}{2} m - 3 \times 2 = 16 \\ \frac{1}{2} m - 6 = 16 \: \: \: | \times 2 \\ m - 12 = 32 \\ m = 32 + 12 \\ \\ m = 44 \: \: \: \: \: \: \: (result)

Hope this helps.

The perimeter of the rectangle is 28 units.
avanturin [10]

The value of w is 5 units

Step-by-step explanation:

Let l be the length of the rectangle

and w be the width

Then

l = 2w - 1

Perimeter = 2(l+w)\\28= 2(2w-1+w)\\28 =2(3w-1)\\28 = 6w -2\\28+2 =6w-2+2\\6w = 30

Dividing both sides by 6

\frac{6w}{6} = \frac{30}{6}\\w = 5

Hence

The value of w is 5 units

Help ASAP!!What is the volume of our planet if we assume that it is a sphere with the radius 3, 950miles? Round your answer to t
zloy xaker [14]

Answer: 258023743333miles³

Step-by-step explanation:

Volume of a sphere = 4/3πr³.

where,

π = 3.14

r = radius = 3950

Volume of a sphere = 4/3πr³.

= 4/3 × 3.14 × 3950³

= 4/3 × 3.14 × 61629875000

= 258023743333miles³

The volume of our planet if we assume that it is a sphere with the radius 3,950miles will be 258023743333miles³
