$\frac{13}{25}=\frac{p}{100} \\\\ p=\frac{13*100}{25} \\\\ p=13*4 \\\\ \boxed{p=52}$

P = 13 x 4 because 25 goes into 100 four times.

13
4 x
52

= 52

Hey there :)

( 5y + 9 )( 6y - 1 )

We need to use FOIL to expand, that is
First Terms
Outer Terms
Inner Terms
Last Terms

First Outer Inner Last
( 5y )( 6y ) + ( 5y )( - 1 ) + 9 ( 6y ) + 9 ( - 1 )
30y² - 5y + 54y - 9

Combine, if any, the like-terms
30y² + 49y - 9

A rectangle whose area is 180 square feet has a width that is 3 feet less than the length. Find the dimensions of the rectangle.

Yuliya22 [10]

Answer:

The length is $15\ ft$

The width is $12\ ft$

Step-by-step explanation:

we know that

The area of rectangle is equal to

$A=LW$

we have

$A=180\ ft^{2}$

so

$180=LW$ -----> equation A

$W=L-3$ ------> equation B

substitute equation B in equation A and solve for L

$180=L(L-3)$

$180=L^{2}-3L$

$L^{2}-3L-180=0$

using a graphing tool------> solve the quadratic equation

The solution is $L=15\ ft$

see the attached figure

<em>Find the value of W</em>

$W=15-3=12\ ft$

The cost of tuition at a college is $12,000 and is increasing at the rate of 6% each year. Use exponential function to find the

Gnesinka [82]

Answer:

The cost of tuition fee after 4 years is $15,149.72.

Step-by-step explanation:

Exponential function:

$A=P(1+r)^n$

A= the amount after n years

P= Initial amount

r= rate of increasing

n= time in years

The cost of tuition at a college is $12,000. It is increasing at the rate of 6% each year.

Here, P= $12,000, r= 6%= 0.06, n= 4 years.

$\therefore A=12,000(1+0.06)^4$

$\Rightarrow A= 12000(1.06)^4$

=$15,149.72

The cost of tuition fee after 4 years is $15,149.72.
