a). 0.45 with a line over the 45 means 0.45454545454545... forever.

It's equivalent to 45/99 which is 5/11 .

b). 0.45 with a line over the 5 means 0.455555555... forever.

It's equivalent to (0.4 + 0.555555.../10)

The 0.4 part is 4/10

The 0.5555555555.../10 part is 5/90 .

(4/10) + (5/90) = 41/90

c). 0.45 means 45/100 . That's 9/20 .

I don't think you're supposed to be posting unit test questions on Brainly.

jamerra received a $3,00 car loan. she plans on paying off the loan in 2 years. at the end of 2 years, jamerra will have paid $4

leonid [27]

The rate of interest is 75 % per year

Solution:

Given that, Jamerra received a $3,00 car loan

she plans on paying off the loan in 2 years

Jamerra will have paid $450 in interest

Therefore, we get

Principal = $ 300

Number of years = 2

Simple Interest = $ 450

Rate of interest = ?

The simple interest is given by formula:

$simple\ Interest = \frac{p \times n \times r}{100}$

Where,

"p" is the principal and "n" is the number of years and "r" is the rate of Interest

Substituting the given values we get,

$450 = \frac{300 \times 2 \times r}{100}\\\\450 = 3 \times 2 \times r\\\\6r = 450\\\\r = \frac{450}{6}\\\\r = 75$

Thus rate of interest is 75 % per year

Which expression is equivalent to -7(y-2)

soldi70 [24.7K]

Hello!

Distributive property: a(b+c)=ab+ac

$a=-7, b=y, c=2$

$-7y-(-7)*2$

Minus and plus sign.

$-7y+7*2$

Then multiply by the numbers.

$7*2=14$

$\boxed{=-7y+14}$

Hope this helps!

Thanks!
