Answer:

82.5

Step-by-step explanation:

Step 1: We make the assumption that 200 is 100 % since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100 % = 200.

Step 4: In the same vein, x % = 165 .

Step 5: This gives us a pair of simple equations:

100 % = 200(1).

x % = 165(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100 % / x % = 200/165

Step 7: Taking the inverse (or reciprocal) of both sides yields

x/100 = 165/200

x = 82.5 %

What is the volume of the following triangular prism?

sergiy2304 [10]

Answer:

Step-by-step explanation:

The formula of a volume of a prism:

$V=BH$

where

B - area of a base

H - height of a prism

In the base we have the right treiangle. The formula of an area of a right triangle is:

$A=\dfrac{ab}{2}$

where

a, b - are legs

We have

$a=6\ ft,\ b=8\ ft$

Substitute:

$B=\dfrac{(6)(8)}{2}=\dfrac{48}{2}=24\ ft^2$

Calculate the volume.

Substitute

$B=24\ ft^2,\ H=12\ ft$

$V=(24)(12)=288\ ft^3$

Answer:

$9x- 60=10$

Step-by-step explanation:

Given

$\frac{3}{4}x - 5 = \frac{5}{6}$

Required

Rewrite to remove fractions

The denominators in the above expression are 4 and 6.

So, first we take the LCM of 4 and 6

$LCM = 12$

Next, multiply both sides of the equation by this LCM (12)

$12 ( \frac{3}{4}x - 5) = \frac{5}{6} * 12$

$12 * \frac{3}{4}x - 12 *5 = \frac{5}{6} * 12$

$3 * 3x- 60=5 * 2$

$9x- 60=10$
