Mrs. Shipley moved at a speed of 12.0266 feet per second which was originally expressed in miles per hour.

The miles per hour multiplied by 1.466667 gives the speed in feet per second.

Mrs. Shipley ran at an average speed of 8.2 miles per hour.

These units must be converted into feet/second.

We know that,

1 miles/hour =  1.466667 feet/second

So, 8.2 miles/hour = 8.2 ×  1.466667 feet/second

∴ 8.2 miles/hour = 12.0266 feet/second

Therefore, Mrs. Shipley ran at a rate of 12.0266 feet per second, which was originally expressed in miles per hour.

Answer:

m<1 = 159˚

m<2 = 21˚

m<4 = 21˚

Step-by-step explanation:

Angle one is a vertical angle to angle 3 so they have the same angle. Angle 2 and 4 are adjacent angles to angle 3, so they are supplementary angles with angle 3, which 180-159 = 21˚.

A person will wait at least 1.8720 seconds before the wave crashes when the waves are crashing onto the beach every 4.8 second

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

[tex]P(X\leq x)[/tex] = x-a / b-a

Uniform distribution from 0 to 4.8 seconds.

This means that a=0 , b=4.8

61% of the time a person will wait at least how long before the wave crashes in?

This is the 100 - 61 = 39% percentile, which is x for which [tex]P( X\leq x)= 0.39[/tex] . So

[tex]P(X\leq x)= \frac{x-a}{b-a}[/tex]

x= 1.8720

the time a person will wait at least 1.8720 seconds before the wave crashes in.

The value of the unknown angle is as follows:

An angle bisector or the bisector of an angle is a ray that divides an angle into two equal parts

Therefore, CH bisects ∠GCD.

Therefore, it divide ∠GCD into two equal halves.

GC bisect ∠BGD.

Therefore, it divides ∠BGD into two equal halves.

Hence,

m∠BGC = m∠CGF

Therefore,

m∠BGC  = 7x - 2

m∠CGF = 8x - 8

7x - 2 = 8x - 8

7x - 8x = -8 + 2

-x = -6

x = 6

Therefore,

m∠BGF = 7x -2 + 8x - 8

m∠BGF = 15x - 10

m∠BGF = 15(6) - 10

m∠BGF = 90 - 10

Therefore,

m∠BGF = 80 degrees

The number of miles he/she can drive with a budget of 150 dollars is 469 miles.

The car rental advertised a car for  $27.95 per day and $0.26 per mile.

If someone rents the car for 4 days and he has a budget of 150 dollars, the number of miles he can drive can be calculated as follows:

The equation used to represent the situation is as follows:

let

x = number of miles drove

Therefore,

150 = 27.95 + 0.26x

subtract 27.95 from both sides of the equation

150 - 27.95 = 27.95 - 27.95 + 0.26x

0.26x = 122.05

divide both sides by 0.26

x = 122.05 / 0.26

x = 469.423076923

x = 469 miles

Therefore, the number of miles he can drive is 469 miles.

Based on the fact that there are courses with 3 credits and 4 credits, with the total that a student can earn being 65 credits, the number of 3 credit courses that the student completed was 19 courses and the number of 4 credit courses was 2 courses.

Assuming that the number of courses worth 3 credits are denoted as x and the number of courses worth 4 credits are denoted by y, the system of equations would be:

3x + 4y = 65

x + y = 21 courses

Using substitution for y gives:

x + y = 21

y = 21 - x

The number of courses with 3 credits is:

3x + 4y = 65

3x + 4(21 - x) = 65

3x + 84 - 4x = 65

84 - 65 = 4x - 3x

1x = 19

x = 19 courses

Number of 4 credit courses is:

= 21 - x

-6 times 3 is obviously -18 and if you type in -6 times -2/3 on a caculator it gives you 4 and its positive because when you times two negatives you get a positive

Value of 'a' for the given statement  the negative a minus four sevenths equals two thirds for a after solving is equal to negative 26 over 21.

As given in the question,

Given statement :

Negative a minus four sevenths equals two thirds for a

Represent the statement in equation form :

-a -(4 / 7) = ( 2 / 3 )

Solve by adding both the side ( 4 / 7 ) we get,

-a - (4 /7) + (4 /7) = (2/3) +(4/7)

⇒ -a = (2/3) + (4/7)

least common multiple of 3 and 7 is 21.

-a = ( 14 /21) + (12 /21)

⇒ -a = 26 /21

⇒ a = -26/21

Therefore, value of 'a' for the given statement  the negative a minus four sevenths equals two thirds for a after solving is equal to negative 26 over 21.
