Pls help and explain

Mathematics
1 answer:
Minchanka [31]2 years ago

Answer:

C

Step-by-step explanation:

The answer is going to be miles per quart.  So B is wrong.

12 gallons allows you to travel 192 miles

1 gallon permits 192 / 12 = 16 miles / gallon. (Must be a truck of some kind).

1 gallon permits 16 miles of driving.

4 quarts (in 1 gallon) permits 16 miles of driving.

1 quart gives 16/4 = 4 miles / quart.

The answer is C.

==========================

There is a slightly shorter way

12 gallons contains 12 * 4 quarts = 48 quarts.

48 quarts permit 192 miles

1 quart permits 192/48 = 4 miles

4miles / quart.

The answer is still C

Help (this for a friend)<br> a 62.1<br> b 117.4<br> c 122.1<br> d 164.5
kramer

Answer:

c. 122.1 cm

Step-by-step explanation:

so l * w + \frac{\pi r^2}{2}

since 6 cm is the diameter

6/2 = 3

the radius (or r) is 3

so 18 * 6 + \frac{3.14 * 3*3}{y}

108 + \frac{3.14*9}{y}

108 + \frac{28.26}{2}

108 + 14.13 = 122.13

simplified: 122.1 cm

hope this helps:)

which ordered pair is a solution of the equation y=4x-7 A. only (2,1) B. only (4,9) C. Both (2,1) and ( 4,9) D Neither
Sphinxa [80]

Hey there! :)

Answer:

C. Both (2,1) and (4,9)

Step-by-step explanation:

To solve this question, simply plug in the coordinates of answer choices given into y = 4x - 7:

A.

1 = 4(2) - 7

1 = 8 - 7

1 = 1. A is correct.

B.

9 = 4(4) - 7

9 = 16 - 7

9 = 9. B is correct.

Therefore, the correct answer is C. Both (2,1) and (4,9) are solutions to this equation.

The measure of the supplement of an angle is 12 more than twice the measure of the angle. Find the measures of the angle and it'
astra-53 [7]
Supplementary angles add up to 180 degrees-

Let x = "the angle"

supplement angle = 2x + 12 // 12 more than twice the measurement of "the angle"

Supplement angle + "the angle" = 180 degrees

(2x + 12) + x = 180 degrees // 2x + 12 is the supplement angle

3x + 12 = 180 //  Simplify

3x = 168 // Subtract 12 from both sides

x =  56 degrees // Divide both sides by 3

The measure of the angle is 56° and its supplement is 124°
