Alicia got 60 questions correct on her science test. If she received a score of 75% , how many questions were on the test?????

Answers

Answer 1

Answer: so since 60=75%
here's a hack. it's not real math
just find a factor of 100 like 2,4,5,10,20,25, or 50
75=3*25

so 60=3*20
3*20=3*25
divide both sides by 3
20=25%
we know that 25% is 1/4 of 100 so
multiply both sides by 4
80=100%

a rectangular has an area of 30 square meters and a perimeter of 34 meters what are the dimensions of the rectangle

Answers

Simple..

For area, it's A=l*w

15*2=30

And, perimeter, it's P=l+l+w+w

15+15+2+2=34

Thus, your answer.

l=15 and w=2,or, w=15 and l=2

L=15
W=2
Or
L=2
W=15
Because perimeter is ehen you add up all the sides and 15 + 2 + 15 + 2= 34. And area is when you multiply lenght times width and 15 x 2 = 30

Which is the best estimate of the weight of a bannanaA. 6 ounces

B. 6 pounds

C. 60 ounces

D 60 pounds

Answers

3 regular bananas weight about a pound.

1 pound = 16 ounces

16 / 3 is approximately 5.

So the best estimate is 6 ounces.

I would believe the best estimate of the weight of a banana to be around 6 ounces. :)

6 3/8 as a decimal and percent. HELP..

Answers

First we need to make it a decimal. So we need the denominator to be 10, 100, 1000, 10000 or something along those guidelines. * can't go in 10, 100 but it can go in the thousandths place ( 1000 / 8 = 125 ) So we multiple the top and the bottom of 6 2/8 by 125. our fraction now looks like this 6 375/1000 In a decimal it looks like 6.375. To make it a percent, move the decimal two places to the right. The percent is 637.5% and the decimal is 6.375. Hope that helps!

the answer should be 6.375 I believe.
