Answer:

Option C. 3.2\ qt

Step-by-step explanation:

Step 1

Find the area of triangle

we know that

The area of a triangle is equal to

A=\frac{1}{2}bh

where

b is the base of triangle

h is the height of triangle

In this problem we have

b=4\ ft

h=8\ ft

substitute in the formula

A=\frac{1}{2}(4)(8)=16\ ft^{2}

Step 2

By proportion

\frac{0.2}{1}\frac{qt}{ft^{2}}=\frac{x}{16}\frac{qt}{ft^{2}}\\ \\x=16*0.2\\ \\x=3.2\ qt

Find the value of 2^-3*3^-2
Sergeeva-Olga [200]

2^{-3}\cdot 3^{-2}

2^-3=\frac{1}{2^3}

3^-2=\frac{1}{3^2}

\frac{1}{2^3}*\frac{1}{3^2}

\frac{1*1}{2^3*3^2}

2^3*3^2=72

=\frac{1}{72}

Hope this helps!

Thanks!

You just graduated college (age 23) and now have your dream job of a computer animator. Your gross salary is 43,000 a year. Answ
Kipish [7]

Answer:

$93.72

Step-by-step explanation:

To be able to find how much is deducted from our paycheck monthly, we have to compute for the total amount left to pay for the health insurance.

Insurance = $4500

Company % = 75% or 0.75

Total amount left = $4500- $4500x0.75

Total amount left = $1125

Now that we know the total amount left, we simply divide the total by 12 to find the monthly payments.

Monthly Payment = $1125/12

Monthly Payment = $93.72

So a total of $93.72 will be deducted from our monthly paycheck for the health insurance.

The equation of line k is y=
Nina [5.8K]

Answer:

Neither parallel nor perpendicular

Step-by-step explanation:

I'm assuming you meant line k is y = 3x -2. If not, this is wrong.

For this, you need to put both lines in point-slope form, or the form that line k is already in. This means you only need to convert line m.

-2r + 6v = 18

6v = 2r + 18

v = 2/6r + 18/6

v = 1/3r + 3

Now you can answer the question.

To be parallel, lines must have the same slope (but a different y-intercept). 3 and 1/3 are not the same, so the lines are not parallel.

To be perpendicular, one line must have the opposite reciprocal (fraction flipped and + goes to - or - to +) of the other. While 3 is the reciprocal of 1/3, they are both positive, so they are not perpendicular.

To be the same line, the equations must be absolutely identical, which they aren't.

This leaves the last option: neither.

Let me know if you need a more in-depth explanation of anything here! I'm happy to help!
