Answer: x = 5

Step-by-step explanation:

If two angles are similar then the ratio of their sides are equal, that is

$\frac{4x}{3x+1} = \frac{15}{12}$

cross multiplying , we have

$4x ( 12 ) = 15 ( 3x + 1 )$

$48x =$ $45x + 15$

$48x - 45x = 15$

$3x = 15$

$x = 5$

Tiffany used to live 15 kilometers away from the school, but after she moved she now lives 9.9 kilometers away. She is _____ per

valkas [14]

Answer:

Tiffany is 34% closer to the school.

Step-by-step explanation:

Given the statement: Tiffany used to live 15 kilometers away from the school, but after she moved she now lives 9.9 kilometers away.

She lived away from the school = 15 km

as, she moved 9.9 km away.

Now, the distance closer to school from where she lived = 15 -9.9 = 5.1 km

To, find how much percent she is closer to school.

Percent states that a number or ratio expressed as a fraction of 100.

$percent = \frac{5.1}{15} \times 100$ = $\frac{51 \times 100}{150} = \frac{51 \times 10}{15}$

Simplify:

percent closer to school = 34%

Therefore, she is 34% closer to the school.

What is the fifth square root of x^16

melamori03 [73]

The fifth square root as in a^(1/2)^(1/2)^(1/2)^(1/2)^(1/2)

Well that is equal to a^((1/2)^5) or a^(1/32)

Since a=x^16 in this case and the rule (b^a)^c=b^(a*c) we have:

(x^16)^(1/32)

x^(16/32)

x^(1/2) or if you prefer

√x
