Answer:
5022 estimate= 5020
18 estimate= 20
So, 5022/20
=251
Step-by-step explanation:
The questions says "about" so that means you have to estimate. First, you estimate the cans, then, you estimate the homerooms = 5022 and 20. Last, you have to divide, 5022/20
=251
Hope it helped!:)
The dimensions would be 2 by 2.
We are fencing in 3 sides. The southern side is twice as expensive as the other two sides; the eastern and western sides together equal as much as the southern side. We have $80 to spend.
20x+10x+10x = 80
40x = 80
x = 2
This means that we can have 2 feet on all sides, for a total of 10(2)+10(2)+20(2)= 80.
Answer:
x = 17
Step-by-step explanation:
<u>Area of a parallelogram:</u>
A = bh
<u>Given:</u>
A = 153
b = 9
<u>Work:</u>
A = bh
h = A/b
h = 153/9
h = 17
Answer:
Percent of water in the mixture=88%
Which is 81.07 square inches of the total volume
Step-by-step explanation:
Volume of the flask=πr^2h
π=3.142
radius=diameter/2
=3.71/2
=1.855
height=8.52 inches
Volume of the flask=πr^2h
=3.142*(1.855)^2*8.52
=3.142*3.441025*8.52
=92.115688686
Approximately 92.12 square inches
Flask contains 12% acid solution and the remaining volume is water
Percentage of water =Total percentage - acid solution percentage
=100%-12%
=88%
Percentage of Water =88%
Percentage of the mixture by volume is water=88% of the total volume
=88/100*92.12
=81.0656 square inches
Approximately 81.07 square inches
