jeka94

Answer:

14.24 foot far is the mirror from the base of the statue.

Step-by-step explanation:

Proportion states that the two ratios or fractions are equal.

As per the statement:

See the diagram as shown below:

Height of a boy = 5.9 foot tall

Height of a statue = 12 foot.

Distance of a boy from the mirror = 7 feet.

Let x be the distance of the mirror from the base of the statue.

then by definition of proportion we have;

$\frac{\text{Height of a boy}}{\text{Distance of a boy from the mirror}}= \frac{\text{Height of a statues}}{\text{Distance of mirror from the base of the statue} }$

Substitute the given values we have;

$\frac{5.9}{7} =\frac{12}{x}$

By cross multiply we have;

$5.9x = 84$

Divide both sides by 5.9 we have;

x = 14.24 ft

Therefore, 14.24 foot far is the mirror from the base of the statue.

HELP i dont know how to do this

Korvikt [17]

Answer

Step-by-step explanation:

First, lets go through B-D and explain why they are correct.

B= f represents the number of flash drives. This means that the coefficient, 10, would be the cost per flash drive.

C= n represents the number of cases of paper. it says so in the question, so that one is a bit easier.

D= f represents the amount of packages of hanging folders. If the coefficient for B is the cost, then that would be the same case for D. Therefore it is correct because the coefficient is 13.

A would be incorrect because the coefficient represents the amount that one item costs. P is the packs of pencils, meaning that it would be $7 per pack of pencils.

Hope this helps!

1f 3/4 gallon of paint can cover 1/8 of the fence how many gallons will he need to paint the whole fence

lilavasa [31]

Answer:

He will need 6 gallons of painting to paint the whole fence.

Step-by-step explanation:

Since 3/4 gallon of paint covered 1/8 of the fence, we have to multiply 3/4 by 8 in order to find the number of gallons that will paint the whole fence (because 8 x 1/8 = 1)

$\frac{3}{4}$ x $\frac{8}{1}$ = $\frac{24}{4}$ = 6

Hope this helps!
