What is the best estimate for the sum of 3/8 and 1/12

Answers

I would round the 8 in 3/8 to ten, along with roundin the 12 in 1/12 to 10 as well. Now you would have 3/10 + 1/10, = 4/10 or 2/5 simplified. Hope this helps, (as this would be my estimate!)

The best estimate would be 11/24, actually that is the exact...

Casey likes to run. She runs an additional 1/4 mile each day. On the last day, she ran 1 1/4 miles. If she ran 1/2 mile on her first day, how many days has she been running?

Answers

Three days
1 1/4 = 5/4
1/2= 2/4
2/4+1/4= 3/4 the first day
5/4-3/4= 2/4
2/4 = 1/4 and 1/4 = two days
the first day+ two days= 3 days

Answer:

120√6

Step-by-step explanation:

Simplify the 5√8 to 2√2

simplify the √18 to 3√2

so it would be √3 * 2√2 * 5 * 2√2 * 3√2

when a square root of an expression is multiplied by itself:

√3 * 2 * 2* 5 * 2 * 3√2

so as we calculate it, 2 * 2* 5 * 2 * 3 = 120 and √2 * √3 = 6

Suppose the lengths of two strings are 10 centimeters and 17 centimeters. Describe how the lengths of these two strings compare

Answers

Answer:

Length of one string is 7 cm less than the length of second string. OR Length of second string is 7 cm longer than length of one string.

Step-by-step explanation:

Given : lengths of two strings are 10 centimeters and 17 centimeters.

To find : Describe how the lengths of these two strings compare.

Solution : We have given that

Length of one string =10 cm.

Length of second string = 17 cm

We can compare both length in many way

Length of one string is 7 cm less than the length of second string.

Length of second string is 7 cm longer than length of one string.

Therefore, Length of one string is 7 cm less than the length of second string. OR Length of second string is 7 cm longer than length of one string.

17 - 10 = 7

The difference is that the second string is 7 centimeters longer.

Ms Jenkins was arranging chairs for school awards assembly each row contained 15 chairs if there were 21 rows how many chairs had to be arranged

Answers

315 chairs you can do it in standard algorithm

315 chairs

You do 21 x 15=315
You do that because there are 15 chairs in 21 rows. So multiply those numbers times each other!

Jesse is investing $2000 more in stocks than in bonds.The bonds pay 7.2% in interest and the stocks pay 6%. If the income from each investment is the same,how much interest will he receive in all? ok the example is saying they multiplied 0.06 and 0.072 by 1000 how did they get 1000? @igreen

Answers

x+2,000=stocks
x=bonds
7.2%⇒(.072)(x)=bonds invested
6%⇒(.06)(x+2,000)=stocks invested

Here is the equation:

x(.072)=(.06)(x+2,000) | Since the income from both equal

You then solve each side first (assume you know how to but if not, let me know)

You first multily the parentheses/x variables
⇒.072x = .06x+2,000(.06)

⇒.072x = .06x+120

You then minus .06x from each side
⇒.012x = 120

You then divide each side by .012
.012x÷.012=x
120÷.012=10,000
x=10,000

Now change the original x variables with 10,000

.072($10,000)=$720 bond interest
They are equal so $720×2=$1440
