Answer:

The surface area of the rectangular pyramid is $SA=109.50\ m^{2}$

Step-by-step explanation:

we know that

The surface area of the rectangular prism is equal to the area of the rectangular base plus the area of the four triangular faces

$SA=(8)(5)+2[14.75]+2[\frac{1}{2}(8)(5)]$

$SA=40+29.50+40$

$SA=109.50\ m^{2}$

This is called a Supplementary Angle, meaning the angles MUST add up to 180 Degree.

Angle 1 will be 94 (94-18 = 76).

Angle 2 will be 13 (8x13 = 104).

(Please mark this as the brainliest if this helps!)

Let's use Newton's Law of Universal Gravitation, which is expressed asF=G(m1m2)/r2We can find the force of attraction between them. Then, to find the acceleration fromF=m1a1 and F=m2a2I'll take it you know the equations of motion for constant acceleration. y=1/2at^2 Obviously, as they accelerate towards each other, the radius between them decreases, meaning the force of gravitation between them increases, meaning they accelerate faster.

The tread life of a particular brand of tire is a random variable best described by a normal distribution with a mean of 60,000

Elis [28]

Answer:

84.13% probability a particular tire of this brand will last longer than 57,100 miles

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

$\mu = 60000, \sigma = 2900$
