Answer:
Determining the height of a cylinder given volume and radius
Step-by-step explanation:
For a right circular cylinder:

Answer:
x=3
Step-by-step explanation:
1/2(2-4x)+2x=13
1-2x+2x=13
4x=13-1
x=12/4
x=3
Answer:
2.36 inches
Step-by-step explanation:
V = 4.18879r³
to determine the value of r, make r the subject of the formula in the above equation
∛(V/4.18879) = R
∛(55/4.18879) = r
r = ∛13.130283
r = 2.36 inches
the hundredth is the second number after the decimal place. To convert to the nearest hundredth, look at the number after the hundredth (the thousandth). If the number is greater or equal to 5, add 1 to the hundredth figure. If this is not the case, add zero
Answer:
#5: 60
#6:55
#7:70
#8:55
11.81
Step-by-step explanation:
#5
∠CFD=60 (all the angles in an equilateral triangle are 60)
#6
∠AFD=150=∠AFB+∠BFC+∠CFD
∴150=∠AFB+35+60
∴∠AFB=55
#7
An isosceles triangle has one unique vertex angle and two equal base angles. All the angles in a triangle add up to 180. We know the base angles (55), so:
180 = ∠ABF + 2(55)
∴∠ABF = 70
#8
∠A=∠AFB = 55 (base angles of an isosceles triangle)
11. An isosceles triangle has one unique vertex angle and two equal base angles. All the angles in a triangle add up to 180. Vertex angle is 18, so the sum of both bases is 180-18=162. Therefore, each base angle is 81.
Answer:
Revenue = 3,776x-4x^2
Step-by-step explanation:
Revenue is given by = price of product * no. of units of product sold.
Given
price of 1 phone = $x
No. of phone sold = 3,776-4x
Revenue = price of 1 phone*No. of phone sold = x*(3,776-4x)
= 3,776x-4x^2
Thus, given statement is true.
