You have an stick that is 25x long. 23 is 7/25th of the length. What is the length?
Answer:
82 1/7 unitsStep-by-step explanation:
The length is 25x and 7/25th of the length is 23:
7/25*25x = 237x = 23x = 23/7The length is:
25*23/7 = 575/7 = 82 1/7 unitsATQ
[tex]\\ \sf\longmapsto \dfrac{7}{25}\:of\:25x=23[/tex]

Refer to the graphic novel frame below. The brochure says that the rope is 500 feet long. Jacob drew a triangle in the sand that is similar to the actual triangle formed by a parasailer and the boat. Use the properties of similar triangles to determine the parasailer's height above
To solve this problem use the property of similar triangles,
"Corresponding sides of the similar triangles are proportional"
By using this property, height of the parasailer is 160 feet.
From the figure attached,
In ΔPQR, a parasailer is a at point P and a boat is at R.Actual length of the rope PR = 500 ftJacob drew a similar triangle ABC in which parasailer is at A and the boat is at C.Let the height (PQ) of the parasailer = x ft
Height of the parasailer AB = 25 ft.
And the length of the rope AC = 2.5 ft.
Since, both the triangles ΔABC and ΔPQR are the similar triangles, their corresponding sides will be proportional.
[tex]\frac{AB}{PQ}=\frac{AC}{PR}[/tex]
[tex]\frac{2}{x} =\frac{2.5}{200}[/tex]
[tex]x=\frac{200\times 2}{2.5}[/tex]
[tex]x=160[/tex] ft
Therefore, height of the parasailer is 160 feet.

At their last babysitting gig, Zainab made $44 for 8 hours of work and Keziah made $47.25 in 9 hours. Each girl charges a different hourly rate. For a 10 hour job, which girl will make more money? How much more?
Answer:
Zeniab makes the most money by $0.25, and would make $2.50 more.
Step-by-step explanation:
Okay, the good news is, this problem is about finding how much you make in an hour.
Zainab makes $44 for 8 hours
and
Keziah makes $47.25 in 9 hours.
in each problem, we can set them up in an equation of
$44=8x
and
$47.25=9x
In the first equation, divide both sides by 8 to isolate the x.
that would be 44/8 = x which is $5.50 per hour for Zainab.
In the second equation, divide both sides by 9 to isolate the x.
That would be 47.25/9 = x which is $5.25 per hour for Keziah.
This means that Zainab would make more per hour, and to find the second part of the question for a 10 hour job,
(You can multiply any number by 10 easily by moving each number up one place. Hundreds go to the thousands when you multiply by 10 as an example. In this problem, 5.50 times 10 would be $55.00 because the 5 behind the decimal would be moved up infront of the decimal)
Zainab would make $55 for 10 hours
Keziah would make $52.50 for 10 hours
Then, take the difference of those final totals, which is $2.50, or multiply $0.25 by 10 to get $2.50

9. Find the exact perimeter of a square whose side length is 5 cube root of 16.
Answer:
35.4 centimeters is your answer
80.5
The edges of a cube are called vertices, The inside of each square that takes up a cube is called, Area...So if the side length = 5 then you need to multiply 5x16 wich = 80 right and the length of each side is 5 so ad a decimal then a 5... btw if yur wondering 80.5 and 35.4 are equivalent
The required perimeter of the square with sides 5∛and 16 is 50.4.
Given that,
To find the exact perimeter of a square whose side length is 5 cube root of 16.
Perimeter is the measure of the figure on its circumference.
What is a square?A square is defined as a geometric shape that has four-sided and also a regular polygon
In the question, we have been given a side of square 5∛16 say a = 5∛16.
Now, the perimeter of a square is given as
The perimeter of the square = 4 a (where a is the side of the square)
= 4 * 5 ∛16
= 4 * 5 * 2∛2
= 50.4
Thus, the required perimeter of the square with sides 5∛and 16 is 50.4.

You spend $30.40 on 4 CDs. Each CD costs the same amount and is on sale for 80% of the original price.
a. Write and solve an equation to find how much you spend on each CD. Let pp represent the price you pay for each CD.
Equation: ___ = 30.40
You spend $___ on each CD
b. The next day, the CDs are no longer one sale. You have $25. Will you be able to buy 3 more CDs?
c. Explain your reasoning for part (b)
Each Cd costs $___ at the regular price , so 3 CDs would cost $___
Answer:
Part A4 CD's cost $30.40, so one CD costs:
4p = $30.40p = $30.40/4p = $7.60Part B80% of the regular price is $7.60
If the regular price is r, we have:
0.8r = $7.60r = $7.60/0.8r = $9.53 CD's at regular price cost:
$9.5*3 = $28.5Since $25 < $28.5, we can't buy 3 more CD's.

Find the slope of the line passing through the points (-9, -2) and (5,-2).
Answer:
0
Step-by-step explanation:
(x₁ , y₁) = (-9, -2)
(x₂ , y₂) = ( 5 , -2)
In these two points, there is no change in the y co-ordinates. So the line is parallel to x-axis.
slope of line parallel to x-axis = 0

For a party, Svetlana brought 4 packages of cookies with 16 cookies in each package. She and her friends ate all but 6 cookies,
Which equation can be used to find C, the total number of cookies they ate?
O A, C = (4x 16) + 6
OB, C = (4 + 16) - 6
OC, C = (6 x 16) - 4
OD. C = (4x 16) - 6
O E C = (6 + 16) + 4
Answer:
Answer is D
C = (4 x 16) - 6
Step-by-step explanation:
There is 4 packages. Packages can hold many cookies in this case 16 cookies can be placed inside 1 package.
The total number of cookies can be calculated:
16 x 4 (4 packages altogether with 16 cookies in each package)
They did not eat 6 cookies so 6 cookies are leftover or remaining:
(16 x 4) - 6 (subtract 6 because they did not eat it, we want what they already ate - takeaway 6)
Basically means: The Total minus The Remaining
(The Total - The Remaining)

The correct expression in the box is | 14.1 - ( - 5.20) |.
What is a number line ?A number line is a horizontal line in which we represents all he real numbers which includes all rational and irrational numbers.
According to the given question we have to find an expression which represents the distance between 14.1 and - 5.20 in the number line.
We know to find the distance between two numbers we subtract the smaller number from the bigger number.
Here the larger number is 14.1 and the smaller number is - 5.20.
∴ { 14.1 - ( - 5.20) }
= 14.1 + 5.20
= 19.3.
