Answers

Answer 1
Answer: SA = s × s × s 

SA = 4 × 4 × 4 = 16 × 4 = 64 mm²

OR

SA = s³ 
SA = 4³ = 64 mm²

Your answer is 64 mm²

1/3 of the beads to be red, the greatest number of beads that will fit on the braid is 12, what other fractions could represent the part of the beads that are red

Answers

4/12 i think i'm not positive tho. Because if you divide 12 by 3 you get 4 and 12 stays the same and you can reduce it to 2/6 or 1/3.

The parking lot for a hotel should have 114 parking spaces. If ech row can have 13 parking spaces, then the minimum nukber of rows should be?

Answers

So @mathmate deleted my comment because "I wasn't explaining my answer" well I did

I clearly stated that you have to make educated guess and I showed how I GOT my answer

so i guess here is my "proper" answer

There is no specific formula for this, so you can make an educated guess

for example:

13*5 = 65 (this isn't right because we need a minimum of 114)

so we continue the guessing

I then next tried

13*9

I got 117,

117 is more than 113

making 9 the minimum amount of rows for the hotel parking lot


there ya go @mathmate is that clear enough?

Amy had homework for math,science,and history.she spent 1/3 of her time working on math and 1/4 of her time working on science.

Answers

First we need to multiply to make the fractions have equal denominators so we can add/subtract.

math: 1/3 x 4/4=4/12
science: 1/4 x 3/3=3/12

Now we can find the time she spent on history (I assume this is what you are looking for)

Total time-math time-science time=history time
12/12-4/12-3/12
=5/12

Amy spent 5/12 of her time working on history.
So,

I will be assuming the same thing as the other user.

First, we have to convert the fractions so that they have common denominators.

(1)/(3) * (4)/(4) = (4)/(12)

(1)/(4) * (3)/(3) = (3)/(12)

Now we add the fractions together.

(4)/(12) + (3)/(12) = (7)/(12)

Now, to find the fraction of the time that Amy spent on history, we need to subtract the sum of the time she spent in math and science from one whole.

(12)/(12)-(7)/(12)=(5)/(12)

Amy spent 5/12 of her time working on history.

What is the decimal .387123 rounded to the nearest thousand

Answers

0.387123

Note the place value of each digit

0
.
3 (tenths)
8 (hundredths)
7 (thousandths)
1 (ten thousandths)
2 (hundred thousandths)
3 (millionths)

to find the nearest thousandths, look at the place value of the ten thousandths. It is a 1. Because it is less than 5, you round down.

0.387123 becomes 0.387

0.387 is your answer

hope this helps
It is the nearest thousandth which is the third decimal place. The answer would be .387 unless the 1 was a 5 or higher then it would be .388
