A rectangular exercise mat has a perimeter of 36 feet. The length of the mat is twice the width. Write and solve an equation to

denpristay [2]

Answer:

Part a) The length of the mat is $12\ ft$

Part b) The area of the mat is $72\ ft^{2}$

Step-by-step explanation:

step 1

Find the length

Let

L-----> the length of the rectangle

W---> the width of the rectangle

we know that

The perimeter of rectangle is

$P=2(L+W)$

$P=36\ ft$

$36=2(L+W)$

$18=(L+W)$ ----> equation A

$L=2W$ -----> equation B

substitute equation B in equation A

$18=(2W+W)$

solve for W

$18=3W$

$W=18/3=6\ ft$

Find the value of L

$L=2(6)=12\ ft$

step 2

Find the area

The area of rectangle is equal to

$A=LW$

substitute the values

$A=(12)(6)=72\ ft^{2}$

Simplify 12cm to 2.5mm

julia-pushkina [17]

Given:

12cm to 2.5mm

To find:

The simplified for of given statement.

Solution:

We know that,

1 cm = 10 mm

12 cm =120mm

We have,

12cm to 2.5mm

It can be written as

$\dfrac{12\ cm}{2.5\ mm}=\dfrac{120\ mm}{2.5 mm}$

$\dfrac{12\ cm}{2.5\ mm}=\dfrac{120}{2.5}$

$\dfrac{12\ cm}{2.5\ mm}=48$

Therefore, the value of 12 cm to 2.5 mm is 48 or 48:1.

I need help on #2 <br> If a=-1/2,b=4,and d=-3, what is the value of 3ab^2-d^3/a

Gre4nikov [31]

First, you should substitute the variables for their value in the expression.

= [ 3 (-0.5) (4)² - (-3) ] / (-0.5)

= [ 3 (-0.5) (4)² + 3 ] / (-0.5)

= [ 3 (-0.5) (16) + 3 ] / (-0.5)

= [ (-1.5) (16) + 3 ] / (-0.5)

= (-24+3) / (-0.5)

= -21 / -0.5

= 42

Ralph chase plans to sell a piece of property for $145000. He wants the money to be paid off in two ways a short term note at 11

Ymorist [56]

Given :

Price of property , P = $145000 .

Money paid off in two ways a short term note at 11% interest and a long term note at 8% interest.

Total interest , I = $13850 .

To Find :

The amount of each note .

Solution :

Let , x money is paid off in 11 % interest rate and ( 145000-x) in 8% interest rate.

Therefore , their sum of interest in mathematics is given by :

$\dfrac{11x}{100}+\dfrac{8(145000-x)}{100}=13850\\\\11x+1160000-8x=1385000\\\\3x=225000\\\\x=\$75000$

Therefore , the amount of note is $75000 and $70000 for 11% and 8% interest rate respectively .

Hence , this is the required solution .
