Answer: 6.95Nm

Step-by-step explanation:

A torque of a circular rotating body is calculated by multiplying the force acting on the centre with it's lever arm. If this force acts at an angle like the one we have in the question, we derive our resultant force and use it in our calculations.

F = 60N

Angle = 75°

Sin 75 = 0.9659

Lever arm = 12cm = 0.12m.

Deriving the resultant torque from the given angle becomes:

T = 60 * 0.12 * sin75 = 6.95Nm.

a right rectangular prism has a length of 2 1/2 feet a width of 3 feet and a height of 1 1/2 ft unit cubes with side lengths of
Annette [7]
Given the original dimensions of:
2 1/2 ft, 3 ft and 1 1/2
After addition of 1/2 ft on both sides, the new dimensions will be:
3 1/2 ft, 4 ft, and 2 1/2 ft
thus the volume of the the prism will be:
Volume=length*width*height
V=3 1/2×4×2 1/2
V=35 ft³

Answer: 35 ft³

A soup company puts 12 ounces of soup in each can. The company has determined that 97% of cans have the correct amount. Which of
lana [24]

Answer:

Option d: n = 36, p = 0.97, x = 36.

Step-by-step explanation:

We are given that a soup company puts 12 ounces of soup in each can. The company has determined that 97% of can have the correct amount.

We have to describe a binomial experiment that would determine the probability that a case of 36 cans has all cans that are properly filled.

Let X = <u><em>Number of cans that are properly filled</em></u>

The above situation can be represented through binomial distribution;

P(X = x) = \binom{n}{x} \times p^{x} \times (1-p)^{n-x} ; x = 0,1,2,........

where, n = number of trials (samples) taken = 36 cans

            x = number of success = all cans are properly filled = 36

            p = probabilitiy of success which in our question is probability that

                  can have the correct amount, i.e. p = 97%

So, X ~ Binom (n = 36, p = 0.97)

Hence, from the options given the correct option which describes a binomial experiment that would determine the probability that a case of 36 cans has all cans that are properly filled is n = 36, p = 0.97, x = 36.

Find the area of a circle with a diameter of 10 ft.
densk [106]

Answer:

25π

Step-by-step explanation:

area of a circle π(r²)

diameter = 2r so we half the given diameter

radius = 5ft

5² = 25

so the answer is 25π

Simplify: x^2-4x-12/x^3-10x^2+24x
Setler [38]

Answer:

(x + 2) / x(x - 4).

Step-by-step explanation:

x^2-4x-12/x^3-10x^2+24x

= (x + 2)(x - 6) / x(x^2 - 10x + 24)

=  (x + 2)(x - 6) / x(x - 4)(x - 6)          x -6 is common to top and bottom so:

= (x + 2) / x(x - 4).
