Use the following scenario to answer the question below:
Stolb23 [73]

The bigger engine is about 235.5 cubic centimeters larger than the smaller engine.

We need the answer in cubic centimeters. So let's convert 350 cubic inches to cubic centimeters. We will do it unit conversion way (the long way).

We will write cubic inches as three inches side-by-side

350 in^3

<h3>What is the ratio of the centimeter?</h3>

This way, we can multiply this by the ratio of centimeters to inches [2.54 cm = 1 inch], so that the units cancel and we have cubic centimeters (what we desire).

350 in^3*3.54cm/1in*3.54cm/1in*3.54cm/1in

So, we can cancel the three inches top and bottom thus we have the answer in centimeters cubed. And the value is

350 in^3*3.54cm/1in*3.54cm/1in*3.54cm/1in.

350 in^3*3.54cm/1in*3.54cm/1in*3.54cm/1in=5735.47.

So 350 cubic inches is approximately 5735.5 cubic centimeters (rounded to 1 decimal place).

This is larger than a 5500 cubic centimeters engine.

5735.5-5500=235.5cubic centimeters.

The bigger engine is about 235.5 cubic centimeters larger than the smaller engine.

Write in point-slope form an equation of the line that passes through the given point and has the given slope. Point: (4, 8); m
Ainat [17]

Answer:

\mathsf{y-8=\cfrac{3}{4}(x-4)}

Step-by-step explanation:

Hi student, let me help you out!

<u>.. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. ... ... ..... ........   ......  ... ......... .... ....</u>

<u></u>

First, let's recall the point-slope form equation: ↪ \mathrm{y-y_1=m(x-x_1)}.

<u>where: </u> y₁ = y-coordinate of the point (the second coordinate), m=slope, x₁=x-coordinate (the first coordinate).

Let's stick in the values accordingly. We obtain the following: \mathrm{y-8=\cfrac{3}{4}(x-4)}, which is our point-slope form equation.

Hope this helped you out, ask in comments if any queries arise.

Best Wishes!

What is the quotient?
Zigmanuir [339]

Answer:

B. Negative two-fifths (-2/5)

Step-by-step explanation:

1. Change the second number into a fraction if it isn't already.

2. Find the reciprocal of the divisor, or second fraction.

3. Multiply the numerators together.

4. Multiply the denominators together.

5. Simplify the answer if possible.

6. Determine if the answer is positive or negative using the sign rules.

Show your work:

-4/5 divided by 2/1

-4/5 divided 1/2

-4 * 1 = -4

5 *  2 = 10

Simplify:

-4/10 = -2/5
