Answer:

9. 108 cm^2

10. 1,080 m^2

Step-by-step explanation:

9. 2(3x4) = 24/2 = 12 (for right triangles)

8x5 = 40 (base rectangle)

3x8 = 24 (left slanted side of prism)

4x8 = 32 (right slanted side of prism)

12 + 40 + 24 + 32 = 108

10. 2(8 x 15) = 240/2 = 120 (for right triangles)

24 x 15 = 360 (base rectangle)

24 x 17 = 408 (right slanted side of prism)

8 x 24 = 192 (left slanted side of prism)

120 + 360 + 408 + 192 = 1,080

Anita's, a fast-food chain specializing in hot dogs and garlic fries, keeps track of the proportion of its customers who decide

damaskus [11]

Answer:

0.2700

Step-by-step explanation:

-Notice that this is a binomial distribution with p=0.52, n=4 and x=3.

-The formula for the binomial probabilities is given as:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}$

The probability than in 4, exactly 3 order their food on the go is:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X=3)={4\choose3}0.52^3(1-0.52)^1\\\\=0.2700$

Hence, the probability that exactly 3 order their food on the go is 0.2700

A lawn mower is pushed a distance of 100 ft. Along a horizontal path by a constant force of 60 lbs. Yhe handle of the lawn mower

olga2289 [7]

For this case we have the following equation:
w = || F || • || PQ || costheta
Where,
|| F ||: force vector module
|| PQ ||: distance module
costheta: cosine of the angle between the force vector and the distance vector.
Substituting values:
w = (60) * (100) * (cos (45))
w = 4242.640687 lb.ft
Answer:
The work done pushing the lawn mower is:
w = 4242.640687 lb.ft
