Answers

Answer 1
Answer:

Answer: t = 51

Step-by-step explanation:

Well hello buddy. How are you doing today? Might be a little bit bad because you have to deal with this weird triangle. BUT DONT WORRY DOG. I GOT YOU.

notice that that 112 number is on a straight line.... and straight lines are 180 degrees

With this in mind, lets subtract: 180 - 112 and we get= 68

ok so now we have these triangle angles: 68 and 61. also keep in mind that all angles of a triangle add up to 180

so 68 + 61 = 129

now do this: 180 - 129

the answer is 51
Answer 2
Answer:

Answer:

51⁰

Step-by-step explanation:

there are 180⁰ on a straight line so if substrate 112⁰ from 180⁰ the answer will be 68⁰ so now we can get T simply like this below

61⁰+68⁰+T=180⁰

129⁰+T=180⁰

T=180⁰-129⁰

T=51⁰

A regression analysis between sales (in $1000) and advertising (in $) resulted in the following least squares line: Y= 32 + 8X. This implies that an increase of $1 in advertising is expected to result in an increase of $40 in sales.( why? could you help explain to me thank you so much)

Answers

Answer:

Step-by-step explanation: This is a question under linear regression analysis.

The question is trying to relate sales (in $1000) and and advertising.

Both sales and advertising are variables and are connected by the equation

Y = 32x + 8

Which is a linear regression equation of 2 variables.

Where x is the independent variable which represents advertising in this case and Y is the dependent variable which represents sales.

At $1 of adverts, we have $40 of sales.

We just simply put the fact that x = $1 (advertising) into the linear regression equation, we have the value of Y ( sales)

Y = 32(1) + 8

Y = 32 + 8

Y = $40.

What is the area of a circular pool with a diameter of 36 ft?

Answers

Answer:

1,017.36ft^2

Explanation:

Area of the circular pool = \pi r^2

r is the radius of the pool

Given

r = d/2

r = 36/2

r = 18ft

Area of the circular pool = 3.14(18)^2

Area of the circular pool = 3.14 * 324

Area of the circular pool = 1,017.36ft^2

Answers

Answer:
C and E would be your answers
Explanation:
C is correct because If you multiple 10 by 200 you get 2,000 and then do 3 times 200 gets 600.
E is correct because if you do 10 x 25 it become 250 and if you do 3 x 25 it equals 75!!

Ella has 164 ounces of lemonade. She fills glasses with8 ounces of lemonade each until all the lemonade is gone.
The last glass is not full. How much lemonade is in the
last glass?

Answers

Answer:

4 ounces

Step-by-step explanation:

We're looking for the remainder of ounces.

To find how many FULL glasses will be made, we divide 8 by 164 and look at the integer part of the number.

164/8=20.5

So 2 full glasses were made.

To find the remainder, we multiply 20 by 8 and subtract from 164.

20\cdot8=160\n\n164-160=4

Hope this helped!

Answer:

4 ounces

Step-by-step explanation:

If you divide the 164 ounces by the 8 ounces per glass, you get 20.5 glasses filled. So, half of the last glass would be 4.
