No Sari is incorrect because 120.78/9.9 is 12.2 and 12 is not greater than 12.2

Answer: Sari had a good estimate for the problem. But she was not correct in saying that her answer was slightly greater than the actual answer. The rounded dividend, 120, is slightly less than 120.76, and the rounded divisor, 10, is slightly greater than 9.9, so the estimate would be less than the actual quotient.

Step-by-step explanation:

Hope this helps :D

evablogger [386]

Answer:

Balloon made by Randi's sister =32

Balloon made by Randi =64

Step-by-step explanation:

Let Randi's sister made x balloons.

Balloons made by Randi =2\times x=2x

total ballons =x+2x=3x

1 cast of 1 ballon =\$0.50

Cost of x balloons =3x\times0.50=1.5x

Given total money made =\$48.0

1.5x=48\\\\x=\frac{48}{1.5}\\\\x=32

ballon made by Randi's sister =32

Ballon made by Randi's =2\times32=64

Pablo and Nadia are playing a game on a coordinate grid. Pablo puts a playing piece at point (-2, 3) and Nadia puts a playing pi
7nadin3 [17]

Answer:

The distance between the two playing pieces is of 6.4 units.

Step-by-step explanation:

Suppose we have two points:

A = (x_{1}, y_{1})

B = (x_{2}, y_{2})

The distance between these points is:

D = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}

Distance between:

A(-2,3) and B(3,-1)

D = \sqrt{(3 - (-2))^{2} + (-1 - 3)^{2}} = \sqrt{41} = 6.4

The distance between the two playing pieces is of 6.4 units.

Edward deposited $6,000 into a savings account 4 years ago. The simple interest rate is 3%. How much money did Edward earn in in
GaryK [48]
Hello IdontKnowHowToMath,

first, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year.

Solving our equation:
A = 6000(1 + (0.03 × 4)) = 6720
A = $6,720.00

The total amount accrued, principal plus interest, from simple interest on a principal of $6,000.00 at a rate of 3% per year for 4 years is $6,720.00.

5/8 of the staff are male 5/12 of the staff works part time at the aquarium what is the fraction of the staff being female
Goryan [66]
I believe the answer is 3/8. The whole portion of employees, which is translated as 8/8 is deducted by 5/8, which is the population of male employees.
