Answer:
length (l)=69 cm
breath(b)=45cm
area (a)= 10560 cm²
height (h)=?
now,
Area of cuboid =2(lb+bh+hl)
10560 cm²=2(60×45+45×h+60×h)
10560 cm²=
<h3>
Answer: 100 revolutions</h3>
This value is approximate because pi = 22/7 is approximate.
===========================================================
Explanation:
Let's find the perimeter of the wheel, aka the circumference
C = pi*d
C = (22/7)*77
C = 242
The distance around the tire is approximately 242 cm
At first glance, it looks like one revolution will do the trick. However, we need to cover 242 meters and not 242 cm.
We can say the following
1 meter = 100 cm
242 meters = 24200 cm .... multiply both sides by 242
One revolution covers 242 cm, which is 1/100 of the distance we need to cover. So that means we need to do 100 revolutions to get to the target we're after.
1 revolution = 242 cm
100 revolutions = 24200 cm ... multiply both sides by 100
---------------------------
We could also use a proportion to solve
(1 revolution)/(242 cm) = (x revolutions)/(24200 cm)
1/242 = x/24200
1*24200 = 242x
242x = 24200
x = 24200/242
x = 100

Answer:
Option B). x = -9, -2 and 8.
Step-by-step explanation:
The given function is f(x) = x³ + 3x² -70x - 144 and f(-9) = 0, f(-2) = 0, f(8) = 0
We have to find the solutions to the equation x³+ 3x² = 70x + 144
Now we rewrite the function in the equation form as
x³ + 3x² - 70x - 144 = 0
x³ + 3x² = 70x + 144
we know for the values of x = -9, -2, and 8 value of the function is 0. So when we rewrite the function in the form of an equation, -9, -2 and 8 will be the zero factors of the equation.
So solutions of the equation are x = -9, -2 and x = 8.
