Answer: what do you mean by a word problem?
Step-by-step explanation: 24 per hour = n times 10 hours = d so, 24(10)= $240
The second part of the equation -
8 hours = d times $20 per hour = n so, 8(20) = $160
$240+$160=$400 last week

1) What is the value of r?
Answer:
r=4-2\sqrt{2}
Step-by-step explanation:
Let's set up an equation! (most cringe phrase ever, but hey, it works)
Because this is a square, we can do something like this: \(\frac{r}{\sqrt{2}}\)+r=2
If we multiply all sides by \(\sqrt{2}\), then we get \(r+r\sqrt{2} = 2\sqrt{2}\)
Time to solve it! (you could've gotten here another way, tho)
\(r(1+\sqrt{2} )=2\sqrt{2}\)
\(r=\frac{2\sqrt{2} }{1+\sqrt{2} }\)
Rationalizing the denominator, we get \(r=4-2\sqrt{2}\)

Mackenzie runs around a circular track 4 times. If the track has a radius of 40 feet, how far did Mackenzie run?
Answer: 320 feet
Step-by-step explanation: The radius is half of the diameter, so 40x2=80. But it says she ran around the track 4 times so you do 80x4=320.

Answer:
7^10 is the answer
Step-by-step explanation:
you just subtract exponents
Answer: The answer is 7^10
Step-by-step explanation:
7^15/7^5 evaluated is 282475249
After evaluating 7^15/7^5 we could then use the process of elimination
- 7^3 = 343
- 7^10 = 282475249
- 7^20 = 1341068619663960000000
and 7^75 = 2.41186503 * 20^63
So, the answer is 7^10

A builder bought 5 houses for $2500000 each. He sold $3 of the houses at a profit of 30% and rest of the houses at a loss of 40% . Find his overall profit or loss percent
Answer:
Step-by-step explanation:
2,500,000 * .3 = 750,000
A) 3* 750,000 = 2,250,000
2,500,000*.4 = 1,000,000
B) 2*1,000,000 = 2,000,000
A-B = profit
profit was 250,000
2,500,000 * 5 = 12,500,000 ( total costs )
12,750,00 ( total sales)
what percent is 250,000 of 12,500,000 ?
250,000 / 12,500,00 = 0.02
this is 2% profit :/ not so good
Matthew visited the fruits garden last weekend and helped farmers count the fruits. There were 10% more dragon fruits than passion fruits. When 75 fruits were added, the dragon fruits were increased by 60% and the passion fruits increased by 9%. How many fruits were there at first?
Answer:
Step-by-step explanation:
let number of passion fruits=x
number of dragon fruits=x+10% of x
=x+0.1 x=(1+0.1)x=1.1 x
total number of fruits=x+1.1 x=(1+1.1)x=2.1 x
1.1x+60% of 1.1x+x+9% of x=2.1x+75
1.1 x+0.6 of 1.1 x+x+0.09 of x=2.1x+75
1.1x+0.66 x+x+0.09 of x =2.1x+75
2.1 x+0.75x-2.1 x=75
0.75 x=75
\(\frac{75}{100}x =75\\x=75 \times \frac{100}{75} =100\\Originally ~total ~number~ of~ fruits=2.1x=2.1 \times100=210\)
Answer:
Step-by-step explanation:
let number of passion fruits=xnumber of dragon fruits=x+10% of x=x+0.1 x=(1+0.1)x=1.1 xtotal number of fruits=x+1.1 x=(1+1.1)x=2.1 x1.1x+60% of 1.1x+x+9% of x=2.1x+751.1 x+0.6 of 1.1 x+x+0.09 of x=2.1x+751.1x+0.66 x+x+0.09 of x =2.1x+752.1 x+0.75x-2.1 x=750.75 x=75

Find the vertical distance between points X(−2,3) and Y(−2,114) .
Answer:
111
Step-by-step explanation:
114-3
Answer:
What I can tell is that they both share the same x coordinate. To help you understand, the horizontal line is from left to right, think of "The sun setting in the horizon.", it is often in the distance as a "left to right" line. So, I hope that helps, this leaves the vertical line as up or down.
With that out of the way, the x-axis lies on the horizontal line, whereas the y-axis lies on the vertical line.
Point coordinates are typically listed as (x, y), so... with that said, to find the distance we'll have to count downwards. As we know, negative x is to the left, negative y is further down, so... -3 to -12 is 9 points away.
Simple method: -3 - 9 = -12, or... -12 - -3 = -12 + 3 = -9.
In other words you get the basic idea, you can also just count, but whatever.

Rihanna planned a rectangular courtyard for a park and made a scale drawing using inches as the unit of measurement. She originally planned for the length of the actual courtyard to be 54 feet, but she decided to change it to 72 feet. If the length of the courtyard is 18 inches in her scale drawing, which statement about the change of scale is true?
One inch represented 1 foot in the first scale, but now 1 inch represents 4 feet in the second scale.
One inch represented 4 feet in the first scale, but now 1 inch represents 3 feet in the second scale.
One inch represented 54 feet in the first scale, but now 1 inch represents 72 feet in the second scale.
One inch represented 3 feet in the first scale, but now 1 inch now represents 4 feet in the second scale.

Please help meeeeeeeeeeeeeeeeeeeeeeeeeeeeeee. I would love the help. tysm and keep safe
Step-by-step explanation:
a. mean= sum of all observations/total number of observations
=149+111+171+166+152+129+162+144/8
=1184/8
=148
b. median= middle value when arranged in ascending order
= 111 129 144 149 152 162 166 171
middle values= 149 and 152
so median = 149+152/2= 301/2=150.5

I am currently 13 times as old as my granddaughter. Next year, I will be 11 times as old as my granddaughter. How old am I now?
Answer:
65 years old.
Step-by-step explanation:
Define the variables:
Let x be the age of the granddaughter.Let y be the age of the grandparent.Given:
I am currently 13 times as old as my granddaughter. Next year, I will be 11 times as old as my granddaughter.Create two equations with the given information and defined variables:
\(\begin{cases}y = 13x\\y + 1 = 11(x + 1)\end{cases}\)
Substitute the first equation into the second equation and solve for x:
\(\implies 13x+1=11(x+1)\)
\(\implies 13x+1=11x+11\)
\(\implies 2x=10\)
\(\implies x=5\)
Substitute the found value of x into the first equation and solve for y:
\(\implies y=13(5)\)
\(\implies y=65\)
Therefore, the age of the grandparent now is 65 years.
Given statements:
I am currently 13 times as old as my granddaughter. Next year, I will be 11 times as old as my granddaughter.Let us represent the character's age by variables. Assuming that the grandparent's age is G and the granddaughter's age is D. Now, using the obtained variables and the statements, create two equations that represents the provided statements. Then, we can compare the equations and simplify if needed to determine the value of the variables.
\(\implies \left[\begin{array}{ccc} \text{G = 13D} \\ \text{G + 1 = 11(D + 1)}\\\end{array}\right]\)
Since G = 13D is in the form of direct variation, we can substitute the value of G into the second equation to determine the value of D (the age of the granddaughter). Then, we can substitute the value of D into any of the two equations to determine the age of the grandparent.
⇒ G + 1 = 11(D + 1)⇒ G + 1 = 11(D + 1) [G = 13D]⇒ 13D + 1 = 11(D + 1)To solve for D, simplify both sides of the equation by using the distributive property. We need to simplify both sides of the equation so that we can isolate the variables on the other side of the equation.
⇒ 13D + 1 = 11(D + 1)⇒ 13D + 1 = 11D + 11Isolate the variables on one side. This step is necessary because it can cancel out the extra variable and simplify the other variable. To do this, you can either add or subtract on both sides of the equation.
Note: I am subtracting 11D on both sides of the equation since it is my preference. But you can also subtract 13D on both sides of the equation.
⇒ 13D + 1 - 11D = 11D + 11 - 11D⇒ 1 + 2D = 11To further isolate 2D, we need to subtract 1 on both sides of the equation to cancel out the 1 on the left-hand side of the equation. Then, we have:
⇒ 1 + 2D - 1 = 11 - 1⇒ 2D = 10But the variable is still not completely isolated since there is a coefficient being multiplied to D. To isolate the coefficient from the variable, we will need to divide the coefficient (2) on both sides of the equation.
⇒ 2D = 10⇒ 2D/2 = 10/2Then, simplify both sides of the equation. Eventually, we will have a variable on one side and a numerical value on the other side.
⇒ 2D/2 = 10/2⇒ D = 5Now we know the age of the granddaughter, we can substitute the age of the granddaughter into one of the equations and simplify it to determine the age of the grandparent. I am going to choose G = 13D since it is easier to simplify. Then, we will substitute the value of D into the equation.
⇒ G = 13D ⇒ G = 13(5)⇒ G = 65 yearsTherefore, the age of the grandparent is 65 years.
