Which jar is the best value? Please show working :) 10 points correct answer :)

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

Answer:

Step-by-step explanation:

Inequality given:

When solving we do steps:

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.

Answer:

b

Step-by-step explanation:

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

Answer:

A. plant 3; plant 3

Step-by-step explanation:

Plant 3 was the tallest at the beginning. We know this because it is the plant with the highest recorded height at time = 0.

Plant 1 grew 3.5 inches over 6 weeks.

Plant 2 grew ~ 2.25 inches over 6 weeks.

Plant 3 grew 4 inches over 6 weeks.

> This means that plant 3 grew the most, or had the greatest rate of change, over the 6 weeks.

Answer:

8 feet tall

Step-by-step explanation:

Divide 816 by 102 to get 8 feet.

Answer:

The hight of each floor is 8(ft).

Step-by-step explanation:

If you divide 816(ft) by 102 floors you will get 8(ft) making each floor 8(ft) because the building's hight divided by the floors would make an amount of the hight of each floor.

Answer:

-24p^3 + 48p^2 -16p

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

Answer:

Which number lies halfway between:

a) 16 and 38 = 28

b) 259 and 361 =310

1004 and 2012?

=1058

The midpoint of all the numbers are given below.

A location that is halfway between two other points is considered to be a line segment's midpoint. The distance between the midway and each endpoint is the same.

We have to find the midpoint of numbers.

a) 16 and 38

16 + 38 = 54/2 = 27

b) 259 and 361 = 620/2 = 310

c) 1004 and 2012 = 1508.

Therefore, all the middle numbers are given above.

Answer:

I THIK D. BECAUAE IS PARALLEL

Answer:

Lines 2 and 4 are perpendicular!

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.

Answer:

-2, - 1.5, - 1, -0.5, 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4

Step-by-step explanation:

Number Line span or range = - 2 to 4

Interval between each successive number = 0.5

Arrangement of values :

-2, - 1.5, - 1, -0.5, 0, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4

Answer:

m = 2 and n = -10

Step-by-step explanation:

The given function is f(x) = x² + 4·x - 6

The form in which f(x) is to be written = (x + m)² + n, which is the standard form of a quadratic equation

We have;

f(x) = x² + 4·x - 6 = x² + 4·x + 4 - 6 - 4

f(x) = x² + 4·x + 4 - 6 - 4 = (x + 2)² - 10

f(x) = (x + 2)² - 10

By comparison with (x + m)² + n, we have;

m = 2, and n = -10

Answer:

m = -1

Step-by-step explanation:

Slope = (y2-y1)/(x2-x1)

Step-by-step explanation:

You have to divide 225 by 2 and that's the answer you should be able to get.

Answer:

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)
