Answer:

75 degrees and 105 degrees.

Step-by-step explanation:

So this is a transversal. We can use a couple different methods to solve this. We can use many different theorems to solve this problem. So we know that m<2=m<4 because of vertical angles, we also know that m<4=m<6 because of alternate interior angles. We also know that m<6=m<8 because of vertical angles. So we know that m<2=m<4=m<6=<8. In a transversal, there are only two different measurements. And those two different measurements add up to 180 degrees. So since once of the measurements is 75, that means the other measurement has to be 105 degrees. Also, we see that m<4 and m<5 are same side interior angles and according to that theorem, they have to equal up to 180 degrees.

The total width of the craft project is an illustration of products

The total width is 77.4 inches

The given parameters are:

Number of pieces = 12

Width of each piece = 6.45

The total width is the product of the number of pieces and the width of each piece.

So, we have:

Total = 12 * 6.45 in

Evaluate

Total = 77.4 in

Hence, the total width is 77.4 inches

For similar triangles ABC and DEF, the value of N=3.

Similarity of a triangle is the ratio of their corresponding sides or angles which are equal.

The given triangles are ABC and DEF,

Side AB = 21, BC = 28, DE = N and EF = 4.

Also, triangle ABC is similar to triangle DEF.

By similar triangle property,

AB/CD = DE/EF

21/28 = N/4

N = 21/7

The approximate APR generated when you borrow $1,000 for 5 years at an add-on interest rate of 6%, = $300

Annual percentage rate is defined as the yearly interest generated by a sum that's charged to borrowers.

The formula for APR = p×t×r/100

The principal amount deposited (p)= $1000

Time (t) = 5 years

At the rate (r) = 6%

Therefore APR=

[tex] \frac{p \times t \times r}{100} [/tex]

[tex] \frac{1000 \times 5 \times 6}{100} [/tex]

[tex] \frac{30000}{100} [/tex]

APR = $300

Therefore, the approximate APR = $300

Answer:

the answer is d) y = cos(x - Pi) - 2

Step-by-step explanation:

you can see that on the graph that os must be -2.. so you can move it for 2 up

than you have to take in count that (x - Pi) so you move your graph for Pi to the left

and than you have to recognize the function.. if it goes through 0 is sin if not is cos

The equation for the graph y = cos(x - Pi) - 2.

You can see that on the graph that os must be -2.

So you can move it for 2 up.

A graph is a mathematical diagram that shows the relationship between two or more sets of numbers or measurements.

Then you have to take into count that (x - Pi).

So you move your graph for Pi to the left

Then you have to recognize the function.

Hey there!

Let's find the slope & y-intercept of each equation.

The first one is y=4x-5.

Please remember that

In other words, in slope-intercept form (y=mx+b), m is always the slope and b is the y-intercept.

Therefore,  the slope of the first linear equation is 4, and the y-intercept is -5.

or

m=4, b=-5 (option A)

Same with the other equation:

m=-1, b=2/3 (option C is the right option)

Hey there!

a) --›initial number = 3750

--›rate = 2.5%

let y be the population t years after 2021

So, y = 3750(1+2.15) ^ t

=> 3750 × 1.0215 ^ t

b) In 2036,

=> t = 2036 - 2021

=> 15

Substitute into the first value

=> 3750 × 1.0215 ^ t

=> 3750 × 1.0215 ^ 15

=> 5159.

Therefore, the population in 2036 would be 5159

Let:

Ms. Barton = b

Mr. Weaver = b + 8

Mr. Fitzgerald = 2b - 15

Mr. Lloyd = 1/2b + 30

Find b:

176 = b + b + 8 + 2b - 15 + 1/2b + 30

176 = 9/2b + 23

153 = 9/2b

b=34

Plug in 9 to b:

Ms. Barton = 34 slices (4th place)

Mr. Weaver = 34 + 8 = 42 slices (3rd place)

Mr. Fitzgerald = 2(34) - 15 = 53 slices (1st place)

Mr. Lloyd = 1/2(34) + 30 = 47 slices (2nd place)
