Answer:-5/6x
Step-by-step explanation:
PLEASE HELP!!! Shasha and Alan are both running on the track Shasha begins at the starting line and is running 5 feet per second Alan begins 30 feet ahead of Shasha and is running at a speed of 3 ft per second how many seconds will it take Shasha to catch up to Alan?
Answer:
All you have to do is multiply 5 and 3 by specific gaps in between new numbers then subtract 30. Keep doing that until you get evenly matched numbers.
Step-by-step explanation:
The answer is 15, it would take 15 seconds for Alan to reach Sasha.

-8>4+2v
How do you do this
Answer:
Step-by-step explanation:
-8 > 4 +2v ; subtract 4 from both sides
-8-4 > 4-4 +2v; calculate
-12 > 2v; divide both sides by 2
-6 > v
TO Know:
apply the same operation to both sides of inequality
if the operation is dividing or multiplying by a negative number change the direction of the inequality
Part A
Using opposite operations, rewrite the equation so s2 is on one side of the equation by itself.
Part B
What is the opposite operation of squaring? Using this opposite operation, rewrite the equation from question 1 so s is by itself on one side of the equation.
Part C
The pyramid of Khufu, also known as the Great Pyramid of Giza, is one of the Seven Wonders of the World. Its volume is about 2,433,400 cubic meters, and its height is about 138 meters. Substitute these values into the equation from Part B, and solve the equation.
Part D
Search the Internet to find the length of each side of the base of Khufu’s pyramid. Does this length match your calculation?
Part E
Khafre was a son of Khufu. He also had a pyramid built, but it was not as big as his father’s. The volume of the Pyramid of Khafre is about 2,115,072 cubic meters, and its height is about 136 meters. Approximate the length of each side of the base?
Part F
Search the Internet to find the length of each side of the base of Khafre’s pyramid. Does this match your calculation?
Part G
About how much longer are the side lengths of the base of Khufu’s pyramid than Khafre’s?
Answer:
Part A: S^2= 3V/H
Part B: S =[tex]\sqrt{3\frac{v}{h} }[/tex]
Part C: s=√3* 2,433,400 /138=230 metres
Part D: This website says that the length of Khufu's Pyramid is about 230 meters. My calculation was correct.
Part E: S = √3*2,115,072/ 136 =216 metres
Part F: The length of Khafre's pyramid is about 215.5 My calculation was a little off, but not by much.
Part G: 14 meters longer
Step-by-step explanation:
Part A:
I am going to solve:
So,
V=1/3 [tex]HS^{2}[/tex]
Then, multiply both sides by 3:
V x 3= 1/3 [tex]HS^{2}[/tex] x 3
So,
3V=[tex]HS^{2}[/tex]
Then, we divide by H:
[tex]\frac{3V}{H}[/tex]=[tex]\frac{HSs^{2} }{H}[/tex]
So,
[tex]\frac{3V}{H}[/tex]= [tex]s^{2}[/tex]
Then switch sides:
[tex]s^{2}[/tex]= [tex]\frac{3V}{H}[/tex]

(a) Reflect the point (5 3) across the x-axis:
(b) Reflect the point(5 3) across the y-axis:
Answer:
(5, -3)
(-5, 3)
Step-by-step explanation:
Reflecting across the x-axis makes the y coordinate change from a positive to a negative and reflecting across the y axis makes the x value negative.
Show that the lines
y = 4x + 2 and 8x + 2y = -3 are parallel
help pls asap ty ! ! !
Answer:
They intersect
Step-by-step explanation:
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel.
Here we have two functions:
1) y = 4x + 2
2) 8x + 2y = - 3
2y = - 8x - 3
// divide both sides by 2
y = - 4x - 1,5
- 4 ≠ 4 , so these lines aren't parallel, maybe you wrote the assignment incorrect (e. g. if there would be " - " before 8 in the second function, those lines would be parallel), here they intersect.

Sam decided to go to the amusement with his sister. He paid $10 for parking and $12.50 per ticket. Determine the y-intercept. Write your answer as an ordered pair (x,y).
Answer:
[tex]y= 10+12.5x[/tex]
Step-by-step explanation:
Given data
He paid $10 for parking and
$12.50 per ticket.
let the number of tickets be x
and let the total cost be y
Hence the expression in terms of x and y is
[tex]y= 10+12.5x[/tex]

Answer:
One bottle of soap will hold 3/8
Step-by-step explanation:
3/4= The amount of soap she has in total
3/4= 6/8 which is the same amount but now we can divide it by 2
.75 (6/8) divided by 2= .375 (3/8)
So each soap dispenser will have 3.75 liters of soap.
Sentences: To check our work
.375x2= .75

For question F it would be 8/30 or .26%
Then for the next answer the most popular movie genre would be romance at 26%.

break-even point?
a. increase prices (4-5%)
b. increase operational capital with a bank loan
c. lower fixed expenses (phone, electric, advertising)
d. lower direct costs (labor, purchasing, controlling, inventory)
Answer:
b
Step-by-step explanation:
increase operational capital with a bank loan
Increase operational capital with a bank loan is not a recommendation the author of the Businesstown.com article makes to lower your break-even point.
What are Expenses?An expense is an item requiring an outflow of money, or any form of fortune in general, to another person or group as payment for an item, service, or other category of costs.
In the article from BusinessTown.com, the author recommends several strategies to lower the break-even point of a business, which is the point where total revenue equals total expenses. The lower the break-even point, the easier it is for a business to make a profit.
Increase operational capital with a bank loan is not a recommendation to lower the break-even point.
Instead, it suggests borrowing more money to finance operations, which can increase the break-even point and the amount of revenue needed to cover expenses.
Hence, increase operational capital with a bank loan is not a recommendation the author of the Businesstown.com article makes to lower your break-even point.

80% of 90 is the same as 8/9 of 90. true or false
20% of 90 is the same as 1/5 of 90. true or false
Answer:
Both true
Step-by-step explanation: 80%*90=72. 72/90=8/9.
20%*90=18. 18/90=1/5
80% of 90 is the same as 8/9 of 90 is false.
20% of 90 is the same as 1/5 of 90 is true.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, 80% of 90 is the same as 8/9 of 90.
80% of 90 is,
= (80/100)×90.
= 8×9.
= 72.
And,
(8/9)×90.
= 8×10.
= 80.
So, 80% of 90 and 8/9 of 90 is not the same.
20% of 90 is the same as 1/5 of 90.
(20/100)×90.
= 2×9.
= 18.
And,
(1/5)×90.
= 18.
So, 20% of 90 is the same as 1/5 of 90.
