the width of a rectangle is half of the length of the rectangle. if the perimeter is 84 inches what is the length of the rectangle?

Answers

Answer:

The length of the rectangle is 28 inches.

Step-by-step explanation:

We have that the width (W) of a rectangle is half of the length (L) of the rectangle:

[tex] W = \frac{1}{2}L [/tex] (1)

Also, the perimeter is 84 inches:

[tex] P = 2W + 2L = 84 in [/tex] (2)

By entering equation (1) into equation (2) we have:

[tex]2(\frac{1}{2}L) + 2L = 84 in[/tex]

[tex] L = \frac{84}{3} = 28 in [/tex]

Therefore, the length of the rectangle is 28 inches.

1 - Find the values of x for which the combined function h(x) = f(x)/g(x) is undefined if f(x) = 5x + 1 and g(x) = x^2 - 9.

x = ±3
x = 3
x = -3
x = ±9

2 - Find the function h(x) = f(x) - g(x) if f(x) = 3^x and g(x) = 3^2x - 3^x.

h( x) = 0
h( x) = -3 ^2x
h( x) = 3 ^x(2 - 3 ^x)
h( x) = 2(3 ^2x)

Answers

Answer:

Part 1)

Part 2)

Step-by-step explanation:

We are given:

[tex]f(x)=5x+1\text{ and } g(x)=x^2-9[/tex]

And that:

[tex]h(x)=f(x)/g(x)[/tex]

And we want to now for which values of x is h(x) undefined.

So, by substitution:

[tex]\displaystyle h(x)=\frac{5x+1}{x^2-9}[/tex]

Remember that for rational functions, the function will be undefined if and only if the denominator is 0.

This is because we cannot divide by 0.

So, to find the values for which the denominator is 0, set the denominator to 0 and solve for x. Therefore:

[tex]x^2-9=0[/tex]

Add 9 to both sides:

[tex]x^2=9[/tex]

Take the square root of both sides. Since we are taking an even-root, we will need plus/minus. Therefore:

[tex]x=\pm 3[/tex]

So, h(x) is undefined for ±3.

Our answer is A.

We are given:

[tex]f(x)=3^x\text{ and } g(x)=3^{2x}-3^x[/tex]

And we want to find:

[tex]h(x)\text{ if } h(x)=f(x)-g(x)[/tex]

So:

[tex]h(x)=3^x-(3^{2x}-3^x)[/tex]

Distribute:

[tex]h(x)=3^x-3^{2x}+3^x[/tex]

Combine like terms:

[tex]h(x)=2(3^x)-3^{2x}[/tex]

Rewrite:

[tex]h(x)=2(3^x)-(3^x)(3^x)[/tex]

Factor out:

[tex]h(x)=3^x(2-3^x)[/tex]

So, our answer is C.

Scott is 72 inches tall and Chris is 185 centimeters tall how tall is Chris in inches?

Answers

Answer:

Around 72.8 inches

Step-by-step explanation:

We are given the infomation that Chris is 185 centimeters tall.

There are 2.54 centimeters in an inch.

185/2.54 = 72.8346 ≈ 72.8

Chris should be around 72.8 inches.

Hope this helps.

Chris should be around 72.8 inches tall.

Here, we have,

given that,

Scott is 72 inches tall and Chris is 185 centimeters tall

We are given the information that Chris is 185 centimeters tall.

now, we know that,

There are 2.54 centimeters in an inch.

Since 1 inch = 2.54 centimeters

all we need to do is to divide 185 by 2.54

i.e. 185/2.54 = 72.8346 ≈ 72.8

The answer will be 72.8.

Chris should be around 72.8 inches.

one 50 pound bag of fertilizer will cover 75 sq,ft of lawn. how many bags of fertilizer will breon need to cover 300 sq.ft of lawn

Answers

Answer: 4 bags.

Step-by-step explanation:

50lb bag = 75sq.ft.

75*4= 300

Answer:

(1, 5 )

Step-by-step explanation:

Given the 2 equations

9x + 3y = 24 → (1)

10x - 2y = 0 → (2)

Multiplying (1) by 2 and (2) by 3 and adding the result will eliminate the y- term

18x + 6y = 48 → (3)

30x - 6y = 0 → (4)

Add (3) and (4) term by term to eliminate y

48x + 0 = 48

48x = 48 ( divide both sides by 48 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (1)

9(1) + 3y = 24

9 + 3y = 24 ( subtract 9 from both sides )

3y = 15 ( divide both sides by 3 )

y = 5

solution is (1, 5 )

Step-by-step explanation:

First, we need to find the LCD (Least common denominator)

Rewriting input as fractions if necessary:

1/10, 1/4, 1/5

For the denominators (10, 4, 5) the least common multiple (LCM) is 20.

Therefore, the least common denominator (LCD) is 20.

Now, we convert:

Red Marbles: 1/10 = 2/20

Blue Marbles: 1/4 = 5/20

Yellow Marbles: 1/5 = 4/20

As we can see, blue has the most. Now we have our answer! Good luck!

Chris works at a jewelry store, and he earns 4% commission on all sales that he makes. If Chris's jewelry sales total $1,370, how much will he earn in commission?

Answers

Answer:

[tex]\boxed {\boxed {\sf \$54.80}}[/tex]

Step-by-step explanation:

Chris earns the commission on the jewelery sales. To calculate what he earned, multiply the commission rate and his sales.

[tex]commission= commission \ rate * sales[/tex]

His rate is 4% and his sales are $1,370

[tex]commission= 4\% * \$1370[/tex]

Convert the percent to a decimal. Divide by 100 or move the decimal two spots to the left.

4/100= 0.04 4.0 --> 0.4 --> 0.04

[tex]commission= 0.04* $1370[/tex]

[tex]commission = \$ 54.8[/tex]

Chris's commission is $54.80
