First we neeed to find the volume of the rectangular prism

V=\text{ l}\times w\times hV=1\times1\frac{1}{6}\times2\frac{1}{6}=1\times\frac{7}{6}\times\frac{13}{6}=\frac{91}{36}in^3

Volume of cube with side lengths 1/6 = 1/6 x 1/6 x 1/6 = 1/216

The number of cubes needed to fill the prism without gaps or overlaps =

=\frac{91}{36}\text{  divide by }\frac{1}{216}=\frac{91}{36}\times\frac{216}{1}=\frac{19656}{36}=546

Howie wants to get a car loan with 4% simple interest rate. If the car
Sergio039 [100]

Answer:  $26,000

Explanation:

i = simple interest

P = 25,000 = amount loaned

r = interest rate in decimal form = 0.04

t = number of years = 1

So,

i = P*r*t

i = 25000*0.04*1

i = 1000

Howie needs to pay $1,000 in interest on top of the $25,000 loaned to him. In total, he needs to pay back 1,000+25,000 = 26,000 dollars.

Free points, please solve -2m+36=2(6m-3)?​
Elan Coil [88]

Answer:

\Huge \boxed{m=3}

Step-by-step explanation:

-2m+36=2(6m-3)

Expanding brackets.

-2m+36=12m-6

Adding 2m and 6 to both sides.

36+6=12m+2m

Combining like terms.

42=14m

Dividing both sides by 14.

3=m
