Answer:

[tex]1,080^{\circ}[/tex]

Step-by-step explanation:

The sum of the interior angles of a polygon with [tex]n[/tex] sides is given by [tex](n-2)\cdot 180^{\circ}[/tex].

Substituting [tex]n=8[/tex], we get:

[tex](8-2)180=6\cdot 180=\boxed{1,080^{\circ}}[/tex]

Rajib wrote the equations y = 8 x minus 2 and y = negative 4 x minus 5. What can Rajib conclude about the solution to this system of equations? The point (2, 14) is a solution to this system of equations. The point (14, 2) is a solution to this system of equations. The point (Negative 4, negative one-fourth) is a solution to this system of equations. The point (Negative one-fourth, negative 4) is a solution to this system of equations.

Answers

Answer:

The point (Negative 4, negative one-fourth) is a solution to this system of equations

Step-by-step explanation:

y = 8x - 2

y = - 4x - 5

y - 8x = - 2 - - (1)

y + 4x = - 5 - - - (2)

Subtract 1 and 2

-8x - 4x = - 2 - (-5)

-8x - 4x = 3

-12x = 3

x = - 1/4

y = 8(-1/4) - 2

y = - 2 - 2

y = - 4

(-1/4, - 4)

Each table in a library can seat up to 5 people. There are enough tables for 75 people. How many tables are there in the library?​

Answers

Answer:

15 tables

Step-by-step explanation:

75/5 = 15

Answer:

There are 15 tables in the library.

Step-by-step explanation:

You know this because you know the library holds 75 people and you know how many people can sit at a table so to find the answer you divide 75 by 5 and you get 15. To check this you can multiply 15 by 5 and you will get 75.

What is wrong with this solution? -6t + 16 = -8 Step One: -6t + 16 = -8 - 16 Step Two: -6 • -6t = -24 • -6 Solution: t = 144

Answers

Answer:

t = 4

Step-by-step explanation:

In step two, instead of multiplying by -6 on both sides, you need to divide by -6 to isolate t.

-6t = -24

÷-6    ÷-6

t = 4

When you multiply by -6 on both sides, the equation would be 36t = 144, which is not what we want. The opposite of multiplication is division, and in order to get the answer, you divide by the number multiplied.

I think this should be it?

THE FASTEST AND MOST ACCURATE GETS THE BRAINLIEST NO LINKS PLS. Hannah and Harold are making cookies for a bake sale, and they need to make a lot of them. They need to make 70 baggies of cookies that each have 4 cookies in them. The recipe they are using says that one batch will make 2 dozen cookies.

Answers

Answer:

They need to make at least 12 batches.

Step-by-step explanation:

First, we need to find how many cookies in total, so we multiply 70 by 4.

70*4 = 280.

Secondly, 1 batch makes 2 dozen cookies, or technically 24 cookies. So we need to find how many batched with 280 divided by 24. This results in 11.6 repeating. But if you round it up, you get 12.

Time to check:

12 * 24 = 288. So it's the amount of cookies needed with 8 remaining.

Hope this helps.

Answers

Answer:

The system of inequalities can be used to find the values of x and y is

z ≥ 40

y ≥ 40

x+y ≥ 80

x+y ≤ 160

Step-by-step explanation:

Let z represent the number of pounds of potatoes and y represent the number of pounds of onions.

In mathematics at least means equal or greater than ,

So applying this property we get

z ≥ 40 →   at least 40 pounds of potatoes

y ≥ 40 → at least 20 pounds of onions

x+y ≥ 80 → combined must be at least 80 pounds

x+y ≤ 160 →  but must not exceed 160 pounds.

So the correct choice is B

A.24 7/12 sq. inches
B. 24 7/12 cubic inches
C.175/6 sq. inches
D. 175/6 cubic inches

Answers

Answer:

Volume of rectangular prism = 175 / 6 inch³

Step-by-step explanation:

Given:

Base area of rectangular prism = 23 ¹/₃ inch² =  70 / 3 inch²

Height of rectangular prism = 1 ¹/₄ inch = 5 / 4 inch

Find:

Volume of rectangular prism

Computation:

Volume of rectangular prism = Base area of rectangular prism x Height of rectangular prism

Volume of rectangular prism = [70 / 3] x [5 / 4]

Volume of rectangular prism = [350 / 12]

Volume of rectangular prism = 175 / 6 inch³
