Answer:

The generator will run for 6 hours.

Step-by-step explanation:

First, find the volume of the gas tank that is on the generator. I am told that the gas tank is a rectangular prism that has the dimensions of 20 cm, 15 cm, and 10cm.

Area of any prism = height * width * length

Area of prism = 20 cm * 15 cm * 10 cm = 3,000 cm cubed

I am told the important info that <u>1,000 cm cubed = 1 liter </u>

Therefore, 3,000 cm cubed = 3 liters

I am also told that the generator will run for 2 hours on 1 liter of gas

Lets make a ratio table:

Hours the generator will run for : liters of gas

                                                   2 : 1

                                                   6 : 3

the generator will run for 6 hours.

Ava used the following equation in order to solve a math problem involving integers.
AnnZ [28]

Answer:

The only equation which is incorrect is in option B.

Step-by-step explanation:

Eva used the following equation in order to solving integers, which is  

\frac{-h}{-k} = j

⇒ j = \frac{h}{k} ......... (1)

Now, if the equation Ava used is correct, then we have to find which of the given equations is not correct.

Now, in option A) it is given that - j = \frac{- h}{k}

⇒ j = \frac{h}{k} which is same as equation (1).

In option B) it is given that - j = \frac{- h}{- k}

⇒ j = - \frac{h}{k} which is not same as equation (1).

In option C) it is given that - j = \frac{h}{- k}

⇒ j = \frac{h}{k} which is same as equation (1).

Again, in option D) it is given that j = \frac{h}{k}

⇒ j = \frac{h}{k} which is same as equation (1).

Therefore, the only equation which is incorrect is in option B. (Answer)

Vesnalui [34]

Answer:

105 is corresponding to angle B, meaning they are congruent. B and x are supplementry meaning they should add up to equal 180.

Since 180 - 105 = 75, those would be your steps and x is 75

Labyrinth Middle School is 363 ft long Tabitha makes a scale model of the skull and the drawing is 33 in Long. What is the scale
san4es73 [151]

1 inch on the drawing represents 11 feet in the labyrinth middle school.

Step-by-step explanation:

Step 1:

The labyrinth middle school is much larger than the drawing. For 33 inches on the drawing, it is 363 feet on the actual school.

So 33 inches on the drawing is equal to 363 feet in the labyrinth school.

Step 2:

To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling.

In this case, the drawing that Tabitha drew is after scaling and the labyrinth middle school is the measurement before scaling

The scale factor = \frac{33}{363} = \frac{1}{11}.

So the scale factor is \frac{1}{11}. This means that 1 inch on the drawing is 11 feet in the actual school.

Evan spent 20 hours doing homework last week. This week he spent 25 hours doing homework. He says that he spent 125% more time d
ahrayia [7]

Answer:

yes he is correct. he spent 125% more time

Step-by-step explanation:

his original time spent  was 20 hours

he spent a new time which is 25 hours

increased time = 25- 20 = 5 hours

% increase = increase/ original ×100%

%increase = 5/ 20 ×100%

= 1/4 ×100%

= 25%

total increment = 100 + 25 =125%
