Write an expression for the sentence of operations described below.
ira [324]

Answer:

Step-by-step explanation:

The word "quotient" means to divide, so the "quotient of 3 and 8" looks like this:

\frac{3}{8}

If we add that quotient to 10, we have

10+\frac{3}{8}

A truck is purchased for $14,000 and will depreciate in value 20% the first year. what will be the value of the truck one year a
grin007 [14]
The truck's values will decrease by 20%. Thus,
New value = 14000 - 0.2 x 14000
New value = 14000(1 - 0.2)
New value = 14000(0.8)
New value = $11,200

For your rock collection display, you want to have at most 25 samples.
mezya [45]

Answer:

\left \{ {y\leq 25-x} \atop {y\geq 3x}} \right.

The graph is attached.

Step-by-step explanation:

Let be "x" the number of metamorphic samples and "y" the number of sedimentary samples.

You know that you want to  to have at most 25 samples, then:

y\leq 25-x

And you want to have at least 3 times as many sedimentary samples as

metamorphic samples, then:

y\geq 3x

Therefore, the system of  inequalities that model the situation is:

\left \{ {y\leq 25-x} \atop {y\geq 3x}} \right.

The y-intercept of the line y=25-x is:

y=25-(0)\\\\y=25

And the x-intercept is:

0= 25-x\\\\x=25

Knowing this, you can graph the line

The y-intercept of the line y= 3x is:

y=3(0)\\\\y=0

And the x-intercept is:

0= 3x\\\\x=0

Knowing this, you can graph the line.

Observe the graph attached, where the solution of the system of inequalities is the intersection of the regions.

M is directly proportional to r2.when r=2,m=14.Work out the value of r when m =224
balandron [24]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ M = k x r^2

Substitute in the values:

14 = k x 2^2

Divide both sides by 2^2 to find k:

k = 3.5

Substitute the new values in:

224 = 3.5 x r^2

Divide both sides by 3.5 to find r^2

r^2 = 64

Square root it:

r = 8

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

-3(4r-8)=-36. <br> HELP!!! Don’t know the answer. Btw, 8th grade homework!! ;)
Dominik [7]
*Sorry I messed up my math please read the new answer.
Use distrubitive property to get rid of parentheses. Multiply -3 by 4r and -8 to get -12r+24=36. Then zero out 24 by subtarcting 24 from both sides. You. should then have -12r=12. Divide by -12 on both sides to get r by itself. Your answer should be r=1*. Hope this helps :)
