Answer:

$h=\frac{SA-2B}{P}$

Step-by-step explanation:

we know that

The formula to calculate the surface area of a prism is equal to

$SA=Ph+2B$

where

P is the perimeter of the base

h is the height of the prism

B is the area of the base

solve the formula for h

That means ----> isolate the variable h

Subtract 2B both sides

$SA-2B=Ph+2B-2B$

$SA-2B=Ph$

Divide by P both sides

$\frac{SA-2B}{P}=h$

Rewrite

$h=\frac{SA-2B}{P}$

9) Let<br> X-2, x, x+3 <br> be the first 3 terms of a geometric sequence. FInd the value of x..

Reil [10]

Hello,

Let's r the ration

We suppose x ≠0

x=r*(x-2)==>r=x/(x-2)

x+3=r*x==> (x+3)/x=x/(x-2)==>(x+3)(x-2)=x²
==>x²+3x-2x-6=x² ==>x-6=0==>x=6

x-2=6-4=4
x=6
x+3=6+3=9
6=4*3/2
9=6*3/2

Ration 3/2
First term: 4

A sports shop has 84 employees. 25% of the employees work part-time. How many part-time employees does the sports shop have?

Zolol [24]

Answer:

The sports shop has 21 part-time employees.

Step-by-step explanation:

Solution:

What is 25% of 84?

.Y is 25% of 84

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 25% * 84

Converting percent to decimal:

p = 25%/100 = 0.25

Y = 0.25 * 84

Y = 21

Or another quicker way....

50% is half of the whole, and 25 is half of 50.

84/2/2

equals 21 too, I don't recommend to use it as row form.

Solve the equation below

Shtirlitz [24]

Answer: The solution should be n = 1.6

Step-by-step explanation:

Solve the equation:

$-\frac{3}{8}n = -0.6$

-Divide both sides by $-\frac{3}{8}$ :

$\frac{-\frac{3}{8}n }{-\frac{3}{8} } =\frac{-0.6}{-\frac{3}{8} }$

$n = \frac{8}{5} =1 \frac{3}{5} = 1.6$
