It is 8/10 mile from liz's house to the market. Liz walked 6/10 mile, stopped for a break, and walked the rest of the way to the market. Which equation represents liz's walk?

Answers

Answer:

The equation that represents Liz's walk is:

5x + 3 = 4

Step-by-step explanation:

Liz walked 6/10 mile, stopped for a break, and walked the rest of the way to the market.

Let Liz's walk after that break be x mile.

Before the break, she had walked 6/10 miles. Adding these distances, she had walked a total of (x + 6/10) miles.

Because it is 8/10 miles from Liz's house to the market, all the walks she had to do to get to the market is 8/10 miles.

That is,

(x + 6/10) is the same as 8/10.

x + 6/10 = 8/10

Multiplying by 10, we have

10x + 6 = 8

Dividing by 2 gives

5x + 3 = 4

And this is the equation we wish to write.

A building engineer analyzes a concrete column with a circular cross section. The circumference of the column is 18π meters.What is the area A of the cross section of the column?
Give your answer in terms of pi.

Answers

Answer:

$A=81\pi\ m^(2)$

Step-by-step explanation:

Step 1

Find the radius of the circular cross section

we know that

The circumference is equal to

$C=2\pi r$

we have

$C=18\pi\ m$

substitute and solve for r

$18\pi=2\pi r$

simplify

$18=2 r$

$r=9\ m$

Step 2

Find the area of the circular cross section

The area of the circle is equal to

$A=\pi r^(2)$

we have

$r=9\ m$

substitute

$A=\pi (9)^(2)$

$A=81\pi\ m^(2)$

Brad and Wes are building a tree house. They cut a 12 1/2 foot piece of wood into 5 of the same length. how long is each piece of wood? show your work

Answers

Answer:

$2(1)/(2)$ foot

Step-by-step explanation:

Brad and Wes cut a $12(1)/(2)$ foot piece of wood into 5 of the same length.

Let length of 1 piece be x

So, Length of 5 pieces = 5x

Total length of wood= $12(1)/(2)=(25)/(2)$

So, $5x=(25)/(2)$

$x=(5)/(2)$

$x=2(1)/(2)$

Hence Length of each piece is $2(1)/(2)$ foot

This is what I did
I divided 12.5/5=2.5 and each pieces of wood would be 2.5 FT.

Which number line represents the solution set for this inequality?

−9x −12 ≤ 42

Answers

Number line 4 will represent the solution set of given inequality

−9x −12 ≤ 42.

What is inequality?

When two numbers or algebraic expressions are in opposition to one another, this is known as an inequality. It can be expressed as greater than, greater than or equal to, less than, or less than or equal to.

Given:

−9x −12 ≤ 42

-9x-12+12≤42+12

-9x ≤ 54

-9x/-9 ≤ 54/-9

x ≤ -6
