The value of a rectangle is 128 cubic yards. The base of the prism has an area of 8 square yards.

san4es73 [151]

Answer:

<h2>16 yards</h2>

Step-by-step explanation:

Given,

Volume of the rectangular prism = 128 cubic yards

Base area of the prism = 8 square yards

Let,

Height of the prism be = h

As we know, 

Base area × height = Volume of the given prism

Therefore, 

By the problem,

=> 8 sq. yd × h = 128 cu. yd

=> 8h = 128

(On dividing 8 from both sides)

$= > \frac{8h}{8} = \frac{128}{8}$

(On Simplification)

=> h = 16

Hence, the height (h) of the prism is 16 yards (Ans)

If the gradient of line A is 4 what is the gradient of the line which is perpendicular to A

zhannawk [14.2K]

Answer:

perpendicular slope = - $\frac{1}{4}$

Step-by-step explanation:

given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$

the given slope m = 4, hence

$m_{perpendicular}$ = - $\frac{1}{4}$

Evaluate each expression if a=2, b=3 and c=4 A.) 2a+4b-c B.) 6(a+c)-b

djyliett [7]

Answer:

Step-by-step explanation:

A.) 2a+4b-c: Replacing a with 2, b with 3 and c with 4, we get:

2(2) + 4(3) - (4) = 4 + 12 - 4 = 12

B.) 6(a+c)-b: Replacing a with 2 and c with 4, we get 6(2 + 4) - 3.

The work inside parentheses should be done first, resulting in 6(6) - 3.

This comes out to 33.

Solve 2/3=1/4k The solution is k=

aleksley [76]

To find k, divide both sides by 1/4

K = 2/3 / 1/4

When dividing by a fraction flip the second fraction over then multiply:

K = 2/3 x 4/1 = (2 x 4) / (3 x 1) = 8/3

K = 8/3 = 2 and 2/3
