To round this we have to go to the thousands place since the thousands place in this question is 8 its closer to 10 so the answer is 10k or 10,000
Answer:
18 km/hr
Step-by-step explanation:
To find the unit rate, we must find the rate in kilometers per hour.
Let’s divide the total kilometers by the total number of hours.
unit rate = kilometers/hours
Juan rode 72 kilometers in 4 hours.
unit rate = 72 kilometers/ 4 hours
unit rate = 72 km/4 hrs
unit rate = 18 km / hr
The unit rate is 18 kilometers per hour.
Answer:
It will cost $512.73
Step-by-step explanation:
9 in by 6 in sandbox cost $228
i.e., 9*6 = 54 in²
54 in² cost $228
1 in² will cost $228/54
≈ $4.22
If the new dimension is 13 1/2 in by 9 in
then area will be 13 1/2*9
27*9/2 = 121.5 in²
The cost of 121.5 in² will be
121.5*4.22 = $512.73
Answer: 172
Explanation:
<u>Mystery</u> <u>Science Fiction</u> <u>Biographies</u>
4x 3x
4y 5y
Science Fiction = 48
3x = 48 ⇒ x = 16
4y = 48 ⇒ y = 12
Mystery: 4x = 4(16) = 64
Biographies: 5y = 5(12) = 60
Mystery + Science Fiction + Biographies = Total
64 + 48 + 60 = Total
172 = Total
