Answer:
x=5
Step-by-step explanation:
3x^2=75
x^2=25
x=5
Answer:
2/3
Step-by-step explanation:
h = height of the cone
Vcone = πr²h/3
H = h/2 = height of the cylinder
Vcylinder = πr²H = πr²h/2
Vcone/Vcylinder = (πr²h/3)/(πr²h/2)
= πr²h/3 x 2/πr²h
= 2/3
Answer:
See below.
Step-by-step explanation:
1.
3x + 7 + 10x + 17 = 180 ( property of inside angles of 2 parallel lines)
13x + 24 = 180
13x = 180 - 24 = 156
c = 156/13
x = 12.
2.
As the triangle is a right triangle:
42.7 + N = 90
N = 90 - 42.7
= 47.3. degrees.
answer:The width of the deck is 22.8 feet.
Step-by-step explanation:
Since we have given that
Area of the deck = 752.4 square feet
Length of deck = 33 feet
Let width of deck be 'x'.
Since Deck is in the shape of rectangle.
As we know the formula for "Area of rectangle ":
\begin{gathered}Area=Length\times width\\\\752.4=33\times x\\\\\dfrac{752.4}{33}=x\\\\22.8=x\end{gathered}
Area=Length×width
752.4=33×x
33
752.4
=x
22.8=x
Hence, the width of the deck is 22.8 feet.
