For a chemistry experiment 3/4 of an ounce of a certain chemical is needed. if a bottle of the chemical holds 96 ounces, how many times can the experiment be completed?

Answers

Answer:

The experiment can be completed 128 times from 96 ounce bottle of chemical.

Step-by-step explanation:

Given that:

Ounces of chemical hold by bottle = 96 ounces

Chemical used for experiment = 3/4 of an ounce = 0.75 ounce

Number of experiments = [tex]\frac{Chemical\ in\ bottle}{Chemical\ used\ for\ experiment}}[/tex]

Number of experiments = [tex]\frac{96}{0.75}[/tex]

Number of experiments = 128

Hence,

The experiment can be completed 128 times from 96 ounce bottle of chemical.

Answer:

Answer: C. Zero

Step-by-step explanation:

The Slope of a Line

Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The line shown in the image is horizontal, i.e. all of its points have the same y-coordinate regardless of their x-coordinate.

Take two random points on the line like (0,-2) and (2,-2), the slope is:

[tex]\displaystyle m=\frac{-2+2}{2-0}=0[/tex]

The slope is zero

6x + 2 - 8x + 7 = 4x + 1 A. 4/3 B. 3/4 C. -4/3 D. -3/4 oc A D B​

Answers

Answer:

A

Step-by-step explanation:

Given

6x + 2 - 8x + 7 = 4x + 1 ← simplify left side

9 - 2x = 4x + 1 ( subtract 4x from both sides )

9 - 6x = 1 ( subtract 9 from both sides )

- 6x = - 8 ( divide both sides by - 6 )

x = [tex]\frac{-8}{-6}[/tex] = [tex]\frac{4}{3}[/tex] → A

What is 8q+12=4(3+3q)

Answers

Answer:

q = 0

Step-by-step explanation:

8q + 12 = 4( 3 + 3q )

Distributive property

8q + 12 = 4 ( 3 + 3q )

8q + 12 = 12 + 12q

Inverse operations

8q + 12 = 12 + 12q

-8q               -8q

12 = 12 + 4q

-12  -12

0 = q

q = 0

Answer:

Q = 0

Step-by-step explanation:

1. Expand.

8q + 12 = 12 + 12q

2.cancle 12 on both sides.

8q = 12q

3. Move all terms to one side.

8q - 12q = 0

4. simplify 8q - 12q to -4q.

-4q = 0

5. Divide both sides by -4.

q=0

therefor, the answer is q=0
