I need help with these questions

natali 33 [55]

Answer: 1/3 = 33.3% or 33 ⅓%

1/9 = 11.1%

2/9 = 22.2%

8/9 = 88.9%

Step-by-step explanation:

Divide the numerator by the denominator. Multiply the quotient by 100 to change the decimal to a percentage.

All of these are repeating decimals, so it may be required to keep at least one decimal place in the percentage, depending on how precise the calculation must be.

(fog)(x)=f(g(x))

f(g(x))=3(-4x+7)+5

Haley measured the distances between her house and two of her friends' houses. ellen's house is 1.41 miles away from haley's, an

Arada [10]

Answer: Ellen's house is farther away by 898 feet.

Step-by-step explanation:

Given: The distance between Haley's house and Ellen's house = 1.41 miles

We know that 1 mile = 5,280 feet

Then, $1.41\text{ miles}=1.41\times5,280\text{ feet}=7,444.8\text{ feet}$

The distance between Haley's house and Dirk's house = 6,547 feet

Clearly, 6,547<7,444.8

And $7444.8-6547= 897.8\approx898$

Therefore, Ellen's house is farther away by 898 feet.
