Answer:
It's 128ft
Step-by-step explanation:
To find how many cubic feet are in this cord of wood, you would just have to multiply
length x width x height
Answer:
A. x
C. x – 5
D. x + 2
Step-by-step explanation:
From the question above, we are asked to find the factors of an algebraic expression that is given as:
x³ - 3x² - 10x
We would use the step of factorisation
Step 1
x(x² - 3x- 10)
The first factor of the algebraic expression has been obtained = x
Step 2
We factorise x² - 3x - 10
x² +2x - 5x - 10
(x²+2x) - (5x - 10)
x(x + 2) -5(x + 2)
(x + 2)(x - 5)
Step 3
x³ - 3x² - 10x
x(x² - 3x- 10)
(x)(x + 2)(x - 5)
Therefore, the factors of the algebraic expression are:
(x), (x + 2), (x - 5)
The diameter is 30 cm, therefore the radius is 15 cm. The circumference of the tire is found by using the formula C = 2πr. C ≈ 2(3.14)(15) ≈ 94.2 cm. 5 km = 500,000 cm (5 x 1000 x 100). 500,000 ÷ 94.2 ≈ 5307.86 or about 5300 times (revolutions). (using π, instead of 3.14, I got 5305.16 revolutions)
Answer:
t ≤ 12/23
Step-by-step explanation:
-48t + 2 ≤ -71t + 14
You would need to get all the numbers on one side and all the variables on the other side.
-48t + 2 -2 ≤ -71t + 14 -2 → -48t ≤ -71t + 12
-48t + 71t ≤ -71t + 71t + 12 → 23t ≤ 12
23t ÷ 23 ≤ 12 ÷ 23 → t ≤ 12/23
So, as before
curved surface area=154=2h(pi)r
total surface area=3 times curved
total=3 times 154
total =462
total=curved+2(area of base)
462=154+2(area of base)
subtract 154
308=2(area of base)
divide 2
154=area of base
area of base=pir^2
solve for radius
154=pir^2
aprox pi to 3.14
154=3.14r^2
divide both sides by 3.14
49=r^2
square root both sides
7=r
RADIUS=7
find hiehgt
we know that 154=2h(pi)r
subsittue 3.14 for pi and 7 for r
154=h2(3.14)(7)
154=h43.96
divide both sides by 43.96
3.5=h
volume=height times pi times r^2
volume=3.5 times pi times 7^2
volume=3.5 times pi times 49
volume=171.5 times pi
volume=171.5pi
aprox pi to 3.14
volume=3.14(171.5)
volume=538.51
radius=7 cm
height=3.7 cm
volume=171.5pi cm^3 or 538.51 cm^3
