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.

Answer:

90.1 m

Step-by-step explanation:

The length of the shortcut is the hypotenuse of a right triangle with side lengths 30 and 85. That length can be found using the Pythagorean theorem.

PQ² = 30² +85² = 8125

PQ = √8125 ≈ 90.1

The length of the shortcut is 90.1 meters.

If a number is multiplied by 7 and this product is increased by 7 the result is 1 less than 9 times the number. What is the numb

Damm [24]

A) x * 7 = y

B) y + 7 +1 = 9x

A) x = y / 7
Substituting this into B)

B) y + 8 = 9(y/7)

Multiplying both sides by 7

B) 7y + 56 = 9y

2 y = 56

y = 28
x = 4

***************************************************
Double Check
4 * 7 = 28 + 7 = 35
9*x = 36

2) x + 1/4 = 7/8

-1/4 -1/4

x = 5/7

3) 3/4x = 5/8

*4/3 *4/3

x = 5/6

Hope this helps! ;)
