Answer:
2.12 ft above ground level
Step-by-step explanation:
Volume of the cylindrical tank is 36*π
Tank is filled to half its capacity, that means tank is filled 18*π, and level of water is 4 feet, then the height of the cylinder is 8 feet
With the above information we can calculate the radius of the base of the cylinder, according to
V = 36*π = π*r²*h ⇒ 36 = r²*h ⇒ 36/8 = r² ⇒ r = 2.12 ft
Then the radius of the base is 2.12 ft
When the cylindrical tank is place on its side, the level of water inside have to be 2.12 ft above ground level. That is the level of half its capacity
The question is
Find the values of x and y
Let
x---------> the number of 6-inch pies Annika sold
y--------> the number of 8-inch pies Annika sold
we know that
x=2y------> equation 1
5x+9y=133---> equation 2
substitute the equation 1 in equation 2
5*[2y]+9y=133
10y+9y=133
19y=133
y=7
x=2y-----> x=2*7-----> x=14
the answer is
the number of an 6-inch pies is 14
the number of an 8-inch pie is 7
Answer:
6) Braden scored 77.
7) Carolyn bought 18 pocket folders.
Step-by-step explanation:
6) 86 - 9 = 77
7) 0.39x = 7.02
step 1- divide both sides by 0.39
x = 18
