If you aren't allowed to use calculators do (1280 - 128pi) but if you are do (877.876140341) Don't forget units in your work and answer.

Step-by-step explanation:

Volume of Rectangular prism = L*W*H = 8*10*16 = 1280in

Volume of Cylinder = pi*r^2*H = 8*pi*r^2

We know that the diameter is 8 (because that's the height of the rectangular prism as stated in the question) and diameter is 2*r thus the radius of the cylinder is 4.

therefore the volume of the cylinder is 8*pi*(4)^2 which is 128pi If you aren't allowed to use calculators do (1280 - 128pi) but if you are do (877.876140341)

The sum is (n-2)180. N is the number of sides. In this case, you have 20 sides. You get (20-2)180, which is 18x180 and results in 3240 degrees. This is the sum!! To get one angle, do the same thing but divide it by 20. The formula, as seen in the question, is (n-2)180/n. Therefore, you have (20-2) 180 divided by the number of signs, which is 20. Since 18 times 180 = 3240 is the (n-2)180, divide 3240 by 20. You get 162° for each angle.

If z = 2, find the value of: a. 6z2–2z+5
b. 64–5z

Answers

Answer:

25 and 54

Step-by-step explanation:

(a)

6z² - 2z + 5 ← substitute z = 2

= 6(2)² - 2(2) + 5

= 6(4) - 4 + 5

= 24 - 4 + 5

= 20 + 5

= 25

(b)

64 - 5z ← substitute z = 2

= 64 - 5(2)

= 64 - 10

= 54

Answers

740.5+360+599.99-1500

Also those some expensive chicken and coleslaw and milkshake.

I personally don't know anyone that pays these much for them, also where did someone get a 1500 dollars coupon???

Answer:

$200.49 was paid.

Step-by-step explanation:

Simply add the prices, then subtract the amount from the coupon.

740.50 + 360.00 + 599.99 = 1,700.49

1,700.49 - 1,500.00 = 200.49

According to the properties of inequality, when should the inequality symbol be reversed when solving a two-step inequality in the form below?

a x + b greater-than c
when a is positive
when a is negative
when b is positive
when b is negative

Answers

Answer:

B. when a is negative

Step-by-step explanation:

Inequality given:

ax + b > c

When solving we do steps:

ax > c - bx > (c - b)/a

At the second step both sides divided by a.

When a is positive the inequality symbol remains as is, when a is negative we have to divide both sides by -1 as well. This will reverse the inequality symbol.

Correct answer choice is B.

a total of 420 tickets were sold for the school play. they were either adult tickets or student tickets. the number of students tickets sold was two times the numberof adult tickets sold. how many adult tickets were sold?​

Answers

108 adult tickets sold.

Explanation:

To do this equation, we can set x equal to the number of adult tickets sold, and then set up the following equation:

x+3x=432

Since there are three times as many student tickets as adult tickets and the total is 432, you can just use all this information together to make an equation. From there, you can combine like terms to create this equation:

4x=432

After this, just divide both sides by 4 to reach the answer of:

x=108

Answers

Given:

The point is (1,-2).

To find:

The function notation of the given point.

Solution:

If a point is (x,y), then its function notation is f(x)=y.

The given point is (1,-2).

Here, x-coordinate is 1 and y-coordinate is -2. So, the function notation of the given point is

[tex]f(x-coordinate)=y-coordinate[/tex]

[tex]f(1)=-2[/tex]

Therefore, the function notation of the given point (1,-2) is f(1) = -2.

Step-by-step explanation:

Okay this isn't to hard for problems like this, you just have to multiply 8p to the numbers in the presentation so let's do it

8p*-3p^2= -24p^3

8*-3=-24

p*p^2=p^3

combine them both and get:

ans: -24p^3

8p*6p=48p^2

8*6=48

p*p=p^2

combine them both and get:

ans: 48p^2

8p*-2=-16p

8*2=-16

-16*p=-16p

ans:-16p

Then combine everything and get:-24p^3 + 48p^2 -16p
