Answer:

614

Step-by-step explanation:

The length of the rectangle is 25 feet and the width of the rectangle is 9 feet.

It is given that,

Explanation:

Let [tex]x[/tex] be the width of the rectangle. Then the length of the rectangle is [tex]3x-2[/tex].

Perimeter of a rectangle is:

[tex]P=2(\text{length}+\text{width})[/tex]

[tex]68=2(3x-2+x)[/tex]

[tex]68=2(4x-2)[/tex]

[tex]68=8x-4[/tex]

Isolate the variable.

[tex]68+4=8x[/tex]

[tex]\dfrac{72}{8}=x[/tex]

[tex]9=x[/tex]

Now, the length of the rectangle is:

[tex]3(9)-2=27-2[/tex]

[tex]3(9)-2=25[/tex]

Thus, the length of the rectangle is 25 feet and the width of the rectangle is 9 feet.

Answer:27/343 or 0.0787172

Step-by-step explanation:

First you need to place the exponent on both the numerator and the demonimator to make 3 to the power of 3 over 7 to the power of 3

Next you evaluate the numerator so 3 to the power of 3 is 27

and 7 to the power of 3 is 343 so your answer in fraction form is 27/343

you can also change into a decimal if you divide the fraction if you need to

Hope this helps

Answer:

[tex](\frac{27}{343})[/tex]

Step-by-step explanation:

This is what you start off with [tex](\frac{3}{7})^{3}[/tex]

[tex](\frac{3}{7})^{3}[/tex] is also equal to [tex](\frac{3}{7})(\frac{3}{7})}(\frac{3}{7})[/tex] because the original equation is [tex](\frac{3}{7})[/tex] multiplied by itself 3 times.

[tex](\frac{3}{7})(\frac{3}{7})}(\frac{3}{7})[/tex]

Multiply the first two fractions straight across

[tex](\frac{9}{49})(\frac{3}{7})[/tex]

Multiply the answer of multiplying the two fractions by [tex](\frac{3}{7})[/tex]

[tex](\frac{27}{343})[/tex]

15%

Step-by-step explanation:

Absent= 6

Total student = 40

[tex] \frac{6}{40} \times 100 \\ \\ \frac{600}{40} = 15\%[/tex]

Step-by-step explanation:

Hey there!!

We can simply do it.

Here,

Total students =40

Absent students = 6

Now,

[tex]absent\% = \frac{no.asent}{total \: student} \times 100\%[/tex]

Keep all values.

[tex]absent\% = \frac{6}{40} \times 100\%[/tex]

= 15%

Therefore, the absent percentage is 15%.

Answer:

the surface  area of a penny = 662.81 mm²

Step-by-step explanation:

given:

A penny is a cylinder with a diameter of 19.05 millimeters

and a thickness of 1.55 millimeters.

find:

what is the surface  area of a penny?

surface area of a cylinder formula:

As = 2 π r h + 2 π r²

let r = 19.05 / 2

r = 9.53 mm

let h = 1.55mm

plugin values into the formula:

As = 2 π (9.53) 1.55    +    2 π (9.53)²

As = 92.76 +  570.05

As = 662.81 mm²

therefore,

the surface  area of a penny = 662.81 mm²

Answer:

the surface  area of a penny = 662.81 mm²

(f o g) (x) means that we substitute 3/x into x for f(x)

(f o g) (x) = [tex]\frac{2x}{3 - x}[/tex]. This is as simplified as it can get.

7/8+3/4=1 5/8

Answer:

All statements are true, but if you try to reverse them they won't necessarily be true.

Let's try:

Square ⇒ Has 4 sides

But if something has 4 sides it doesn't mean it's a square (example: rectangle)

Angle is 80° ⇒ acute angle

But acute angle is any angle below 90°, not just 80° so the reverse isn't true.

x – 17 = 4 ⇒ x = 21

And if we reverse

x = 21 ⇒ x – 17 = 4

we see that it's true for either direction.

x = 7 ⇒ |x| = 7

But |x| = 7 doesn't mean that x has to be 7, x can also be -7, so the reverse isn't true.

x – 17 = 4, then x = 21
