Can somebody please explain and answer this for me? I really don't get it.

Answer: 12a^3
Explanation: You would get the missing side to complete the perimeter by using the pythagorean theorem so 3^2+4^2=c^2 so you would get 9+16=c^2 which would become 25=c^2. That would get you 5 as the square root of 25 is 5 so in total, it would all be 3a^3+4a^3+5a^3 which would equal 12a^3.
(^ are for exponents) I might be wrong but hopefully it helps a bit. :)

Help me please, you get 50 points. This is easy I just need help

Fraction -> Decimal

4/5 = 0.8

1/8 = 0.125

Decimal -> Percent

0.22 * 100% = 22%

0.47 * 100% = 47%

Percent -> Fraction

34% / 100 = 0.34 = 17/50

25% / 100 = 0.25 = 1/4

Fraction -> Percent

1/3 = 0.33... * 100% = 33.3%

2/5 = 0.4 * 100% = 40%

Decimal -> Fraction

0.65 = 65/100 = 13/20

0.4 = 4/10 = 2/5

Percent -> Decimal

81% / 100 = 0.81

4% / 100 = 0.04

Best of Luck!

Mark has $100,000 to invest. His financial consultant advises him to diversify his investment in three types of bonds: short-ter

galina1969 [7]

Answer:

Short-Term investment: 5000$

Intermediate-Term investment: 65000$

Long-Term investment: 30000$

Step-by-step explanation:

To construct our first equation lets define sort-term bond investment as x, long-term investment as y.

So the equation is:

$x*0,04+(100000-x-y)*0,05+y*0,06=5250$

From the equation it is found that:

$y=25000+x$

Instead of y, if we put 25000+x the equation will be as following:

$x*0,04+75000*0,05+(25000+x)*0,06=5250$

From the equation it is found that:

$x=5000$

Short-Term investment is 5000$

$x+25000=y$

Long-Term investment is 30000$

Rest of the money is Intermediate-Term investment 65000$

Does the equation −2x + y = 0 represent a direct variation? If so, identify the constant of variation.

Vikentia [17]

Adding 2x to both sides we get

y = 2x

This is direct variation where the constant is 2.
