If 2/5 divided by blank = 4/5 what is blank

1 answer:

6 0

2/5 ÷ x = 4/5
multiply both sides by x to get it out of the denominator.
2/5 = 4/5x
now divide each side by 4/5 to get x by itself.
2/5 ÷ 4/5 = x
divide fractions by multiplying the reciprocal of the divisor.
2/5x × 5/4 = x
10/20 = x
1/2 = x

So 2/5 divided by 1/2 =4/5

Find the surface area of the triangular prism

lesya692 [45]

The surface area of the triangular prism is 1664 square inches.

Explanation:

Given that the triangular prism has a length of 20 inches and has a triangular face with a base of 24 inches and a height of 16 inches.

The other two sides of the triangle are 20 inches each.

We need to determine the surface area of the triangular prism.

The surface area of the triangular prism can be determined using the formula,

$SA= bh+pl$

where b is the base, h is the height, p is the perimeter and l is the length

From the given the measurements of b, h, p and l are given by

$b=24$ , $h= 16$ , $l=20$ and

$p=20+20+24=64$

Hence, substituting these values in the above formula, we get,

$SA= (24\times16)+(64\times20)$

Simplifying the terms, we get,

$SA=384+1280$

Adding the terms, we have,

$SA=1664 \ square \ inches$

Thus, the surface area of the triangular prism is 1664 square inches.

A corporate team-building event costs $32, plus an additional $1 per attendee. If there are 66 attendees, how much will the corp

faust18 [17]

Answer:

corporate team-building event cost will cost $98

Step-by-step explanation:

A corporate team-building event costs $32, plus an additional $1 per attendee.

Let cost be C

The expression for the above statement

C($)= 32+n(1)

Where n is the number of attendees

So a situation where there are 66 attendees, the total cost will be

C($) = 32 +66(1)

C($) = 32+66

C($)= 98
