Lines g and h are parallel and m 1 = 65°. What is m 8?



A.
25°

B.
65°

C.
115°

D.
155°

Answers

Answer:

Option B 65\°

Step-by-step explanation:

we know that

If the lines g and h are parallel

then

m<8=m<1 -----> by alternate exterior angles

we have that

m<1=65\°

therefore

m<8=65\°
m 1 = m 4 (v.o.a.)
since g parallel to h
m 4 = m 8
m 8 = m 1 = 65°

Mason is going to have a lemonade stand. His Aunt buys him 10 lbs. of Lemons. if he sells each cup for a quarter,how many cups does he need to sell to pay her back?The Price of 1 lb. of Lemons is $0.89.

I have already did 0.89 x 10 which gives me 8.90.

Please Help

Answers

8.90 divided by 0.25= 35.6 (round up to 36 because you cant sell .6 cups of lemonade)

he would have to sell 36 cups of lemonade to pay his aunt back

after he sells 36 cups and pays his aunt back the $8.90 he will have $0.10 left to keep for himself
Okay, so first we do:

10 lbs × $0.89 = 8.90 (Which you did already)

Then we see how many cups he needs to sell, in order to get to $8.90.

.25 × 36 = $9

So that would be the approximate answer. 

The exact answer would be .25 × 35.6 = $8.9 or $8.90

Hope that helps!

sonja and jake just got married. they received $4,500 in gift money and deposited it into a savings account that pays 1.85% simple interest.How much will they have in savings after 3 years?

Answers

The total amount in savings after 3 years is $ 4749.75

Solution:

Sonia and Jake received $4,500 in gift money and deposited it into a savings account that pays 1.85% simple interest

To find: Amount after 3 years

The total amount after 3 years is given as:

total amount = principal amount + simple interest

The simple interest is given as:

\text {simple interest }=\frac{\text { principal } * \text { number of years } * \text {rate of interest }}{100}

Here principal amount = $ 4500

Rate of Interest = 1.85%

Number of years = 3 years

Substituting the above values in formula we get,

\text { simple interest }=(4500 * 1.85 * 3)/(100)

\text {simple interest }=45 * 1.85 * 3=249.75

Thus simple interest = $ 249.75

total amount = principal amount + simple interest

total amount = 4500 + 249.75

total amount = $ 4749.75

Thus the total amount after 3 years is $ 4749.75

Ruby ate 1/3 of a pizza, and Angie ate 1/5 of the pizza. How much of the pizza did they eat in all?

Answers

Find common denominators. Multiply 5 to numerator and denominator of 1/3, and 3 to the numerator and denominator of 1/5

(1/3)(5/5) = 5/15

(1/5)(3/3) = 3/15

Add

5/15 + 3/15 = 8/15

Ruby and Angie ate 8/15 of the pizza.

hope this helps

i think it is 8/15 of the pizza
