If you know that 84 is 70% of the whole, how can you use proportional reasoning to determine the whole?
A: 70100 shows 70% as a ratio. The ratio 84x compares 84 to the whole, x. Write an equation so that the first ratio is equal to the second ratio. Solve for x : x = 120.
B: 70100 shows 70% as a ratio. The ratio 84x compares 84 to the whole, x. Write an equation so that the first ratio is multiplied by the second ratio. Solve for x : x = 58.8.
C: 70100 shows 70% as a ratio. The ratio x84 compares 84 to the whole, x. Write an equation so that the first ratio is multiplied by the second ratio. Solve for x : x = 120.
D: 70100 shows 70% as a ratio. The ratio x84 compares 84 to the whole, x. Write an equation so that the first ratio is equal to the second ratio. Solve for x : x = 58.8.

Robert earns $8.65 per hour mowing lawns. A) Write a rule for money m as a function of the number of hours h spent mowing lawns. B) How much does Robert earn if she works 3 hours and 25 minutes?
Answer:
A) [tex]m=8.65h[/tex]
B) $29.58
Step-by-step explanation:
Earnings per hour = $8.65
To find:
A) Write a rule for money m as a function of the number of hours h spent mowing lawns.
Earnings done in one hour = $8.65
Number of hours = [tex]h[/tex]
To find the total earnings, [tex]m[/tex] as a function of number of hours [tex]h[/tex], we need to multiply per hour earnings with number of hours [tex]h[/tex].
Therefore, the equation is:
[tex]m=8.65h[/tex]
B) How much does Robert earn if she works 3 hours and 25 minutes?
First of all, let us convert 3 hours and 25 minutes to hours.
3 hours 25 minutes = 3.42 hours
Therefore, total earnings are:
[tex]m = 8.65\times 3.42 = \$29.58[/tex]

Answer:
The rate is 15 minutes per meter.
Step-by-step explanation:
It takes 9 minutes to fill a depth of meters.
Filling meters take 9 minutes time.
Filling 3 meters of the aquarium takes = 45 minutes time (Multiplying by 5 both the numbers).
In order to fill 1 meter of the aquarium it will take minutes (Dividing by 3 both the numerical values).
===================================================
Work Shown:
8 minutes = (2/5) meters
5*(8 minutes) = 5*( (2/5) meters )
40 minutes = 2 meters
40/2 minutes = 2/2 meters
20 minutes = 1 meter
The unit rate in minutes per meter is 20 minutes per meter.
In other words, it takes 20 minutes to raise the level 1 meter.

Which inequality correctly compares Three-fourths, One-seventh, and Five-sixths? One-seventh < Three-fourths < Five-sixths One-seventh < Five-sixths < Three-fourths Three-fourths < Five-sixths < One-seventh Three-fourths < One-seventh < Five-sixths
Answer:
The inequality which correctly compares Three-fourths, One-seventh, and Five-sixths is : One-seventh < Three-fourths < Five-sixths.
The first option is correct.
Step-by-step explanation:
To determine which inequality correctly compares Three-fourths, One-seventh, and Five-sixths, we will arrange them in ascending order.
To do this, first, we will determine the LCM of the fractions denominators..
Three-fourths, One-seventh, and Five-sixths
[tex]\frac{3}{4}, \frac{1}{7}, and \frac{5}{6}[/tex]
The denominators are 4, 7 and 6.
LCM of 4,7 and 6 is 84
Then, we will write the fractions in a form whereby they all have the same denominators.
[tex]\frac{3}{4}, \frac{1}{7}, and \frac{5}{6}[/tex] can be written as
[tex]\frac{63}{84}, \frac{12}{84}, and \frac{70}{84}[/tex]
The resulting order of the numerators gives the order of the fractions.
Now, we will arrange [tex]\frac{63}{84}, \frac{12}{84}, and \frac{70}{84}[/tex] in ascending order. This becomes
[tex]\frac{12}{84}, \frac{63}{84},and \frac{70}{84}[/tex].
∴ The ascending order of the fractions is [tex]\frac{1}{7}, \frac{3}{4},and \frac{5}{6}[/tex].
That is, One-seventh, Three-fourths, and Five-sixths.
Hence, we can write that
One-seventh < Three-fourths < Five-sixths.
This is the inequality which correctly compares Three-fourths, One-seventh, and Five-sixths

2) Jarrah needs no less than $159 to purchase a new guitar. He already has $38 in his savings account. He
has a plan to rake and bag leaves in his neighborhood to make more money. He decides to charge $5 a
bag. What is the minimum number of full bags of leaves that Jarrah needs to rake in order to have
enough money to buy the guitar? Show your work/thinking.
Answer: Jarrah has to rake 25 bags.
Step-by-step explanation: Jarrah
Jarrah needs to get $159 dollars, right? Well since he already has $38, we just need to subtract 159 and 38. 159-38 is 121. (121 is how much heneeds )Each bag raked costs $5, and 5 can't go into 121, so it's best to have more than less. Multiply 5 and 25, and you will get $125. That is more than enough, you cannot do 5x24 because it would be 120, which is too low. Therefore, Jarrah needs to rake 25 bags.

If triangle ABC has the following angle measurements, find the value of Angle A, Angle B, and Angle C.
∠A=4x − 17
∠B= 3x + 8
∠C= x + 13
Answer:
b
Step-by-step explanation:
Answer:
Step-by-step explanation:
4x - 17 + 3x + 8 + x + 13 = 180
8x + 4 = 180
8x = 176
x = 22
<A = 4x - 17
<A = 4*22 - 17
<A = 88 - 17
<A = 71
============
<B = 3x + 8
<B = 3*22 + 8
<B = 66 + 8
<B = 74
============
<C = x + 13
<C = 22 + 13
<C = 35
A B and C add to 180 as they should.

The earth spins 360 degrees about its axis in 24h. How many degrees does it spin in 10h?
if I get another unreasonable answer OHFUSHASHDF
Answer:
150
Step-by-step explanation:
To find out how much it spins in one hour do 360 divided by 24= 15, and you need to find how much it spins in 10 hours so do 15 x 10=150
Answer:
150 degrees.
Step-by-step explanation: Just divide 360 by 24 then times by 10.
The area of a rectangle a=1(w) is represented by the expression 24x6y15. If the width of the rectangle is 2x3y9, what is the length of the rectangle
Answer:
Length of rectangle is: [tex]Length=12x^3y^6[/tex]
Step-by-step explanation:
The area of rectangle = [tex]24x^6y^{15}[/tex]
Width of rectangle = [tex]2x^3y^9[/tex]
We need to find length of rectangle
The formula used is: [tex]Area=Length\times Width[/tex]
Putting values and finding length
[tex]Area=Length\times Width\\24x^6y^{15}=Length\times 2x^3y^9\\Length=\frac{24x^6y^{15}}{2x^3y^9} \\Length=12x^{6-3}y^{15-9}\\Length=12x^3y^6[/tex]
So, Length of rectangle is: [tex]Length=12x^3y^6[/tex]
I need help with 13 and 14
Answer:
13) x = 62
14) x = 2.5
y = 5.88888889
Step-by-step explanation:
x = 62 because x is the alternate interior angle of 62.
37x - 19 = 29x + 1 (subtract 29x on both sides)
8x - 19 = 1 (add 19 on both sides)
8x = 20 (divide by 8)
x = 2.5
Plug 2.5 into 29x + 1 to find 9y + 25
29(2.5) + 1 = 73.5
9y + 25 = 73.5 (subtract 25 on both sides)
9y = 48.5 (divide by 9 on both sides)
y = 5.388888889
It all checks out!

Answer:
Step-by-step explanation:
Margo is selling boxes of nuts to raise money for her club. She finds that 3 out of every 7 boxes of nuts are cashews. Write a ratio to represent the number of boxes of cashews to the total number of boxes sold.
Answer:
3 : 7
Step-by-step explanation:
make sure the three of on the left
The number of boxes of cashews to the total number of boxes sold is expressed as 3:7 in ratio.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other. The general form of expressing a ratio between two quantities say 'a' and 'b' is a: b
Margo finds that 3 out of every 7 boxes of nuts are cashews.
In order to calculate the ratio of two quantities, we can use the following steps
First, we must determine the quantities for both scenarios for which we are calculating the ratio. In this situation, there are three cashews and seven boxes.
Write it as a fraction, a/b. As a result, we write it as 3/7.
Therefore, the number of boxes of cashews to the total number of boxes sold is expressed as 3:7 in ratio.
