Sean earns 6.70 per hour working after school.He needs at least $155 to buy a new video game.Write an inequality that describes

Scorpion4ik [409]

Answer:

The inequality representing how many hours he should work in order to reach his goal would be

$x\geq 23.14$

where $x$ represents the number of hours Sean works.

Step-by-step explanation:

Hourly earnings of Sean from after school job = $6.70

Let Sean work for $x$ hours in order to earn at least $155.

We will use unitary method to find earning for $x$ hours.

If 1 hour earnings = $6.70

∴ in $x$ hours earnings in dollars would be = $6.70\times x=6.7x$

Now, we know Sean needs at least $155 to buy a new video game.

This means his earnings working $x$ hours must be at least $155.

Thus, the inequality representing how many hours he should work in order to reach his goal would be

$6.7x\geq 155$

Dividing both sides by 6.7.

$\frac{6.7x}{6.7}\geq \frac{155}{6.7}$

$x\geq 23.14$ (Answer)

Thus, Sean should work a minimum of 23.14 hours to earn at least $155.

A recipe that yields 12 of soup calls for 28 ounces of beef broth. How many ounces of beef broth do you need to make 18 cups of

Luba_88 [7]

Answer:

we know that

A recipe that yields 12 cups of soup calls for 28 ounces of beef broth

so

by proportion

Find the ounces of beef broth needed to make 18 cups of soup

\frac{28}{12} \frac{ounces}{cups} =\frac{x}{18} \frac{ounces}{cups} \\ \\12*x=18*28\\ \\x=18*28/12\\ \\x=42\ ounces

therefore

the answer is

42\ ounces

a tree 20 feet tall with a circumference of 3 ft has a vine wound around 7 times. How long is the vine?

FinnZ [79.3K]

If the tree is 20 feet tall with circumference 3 feet then the length of vince is around 21 feet.

Given the height of tree is 20 feet and the circumference of tree is 3 feet.

We have to find the length of vine.

Circumference is the perimeter of a circular object. Because the trunk of a tree is in shape of circle so the perimeter of the trunk is 2πr.

We have been given the circumference of tree be 3 feet.

Circumference=2πr

Because vine is 7 times the circumference so the length of vine being:

Length of vine=7*3

=21 feet.

Hence if the tree is 20 feet tall with circumference 3 feet then the vince is around 21 feet long.

I just want to check my answer, what is the slope of (-19, -6), (15,16)?

galina1969 [7]

$slope=\frac{y_2-y_1}{x_2-x_1}\\\\ 
(x_1,y_1)=(-19,-6)\\ 
(x_2,y_2)=(15,16)\\\\
 slope=\frac{16+6}{15+19}=\frac{22}{34}=\frac{11}{17}\\\\
Slope\ is\ equal\ to\ \frac{11}{17}.
