Answer:
The two trains are closing the initial distance between that of 280 miles by the sum of their two speeds. 80mph + 60mph = 140 mph. With the speed that the distance between the trains is closing, we can divide the starting distance to find out the number of hours until the trains pass. 280 miles / 140 mph = 2 hours. Since the trains left at 3:00 and will pass each other in 2 hours, they will pass each other at 5:00.

A ladder is leaning against a building so that the distance from the ground to the top of the ladder is 3 feet less than the length of the ladder. Find the length of the ladder if the distance from the bottom of the ladder to the building is 9 feet.
Answer:
15 ft
Step-by-step explanation:
This is another classic case of Pythagoras theorem. To start with, let's assume that the length of the ladder we're looking for is x
We're told that the height of the building the ladder is leaning on is, x - 3
Also we're told that the distance at an adjacent from the ladder is 9 ft.
If we use Pythagoras theorem, we have
x² = (x - 3)² + 9²
x² = x² - 6x + 9 + 81
On rearranging, we have
x² - x² = -6x + 90
6x = 90
x = 90 / 6
x = 15 ft
Therefore, the length of the ladder is found to be 15 ft

A football is selling for 35% off the original price. The original
price was $60. What is the sale price of the football?
Answer:
$39
Step-by-step explanation:
First we need to find 35% of 60:
0.35 * 60=21
All we have to do after that is subtract 35% of 60 from 60:
60-21=39
And yeah the answer is 39!

Caroline earns $106.25 for 5 hours of work. If she makes a constant hourly wage, which table represents the relationship between the number of hours she works and her total earnings?
Answer: A
Step-by-step explanation:
Caden, Zoe, and Sophia shared a pizza. Caden ate 20 percent of the pizza. Zoe ate 50 percent more of the pizza than Caden ate. Noah ate 50 percent more of the pizza than Zoe ate, and Sophia ate the rest of the pizza. Find the percentage of the pizza that Sophia ate.
Answer:
Step-by-step explanation:
c=.2, z=1.5(.2), n=1.5(1.5).2
s+c+z+n=1
s+.2+1.5(.2)+1.5(1.5).2=1
s+.2+.3+.45=1
s+.95=1
s=.05
So Sophia ate 5% of the pizza
Answer:
Sophia ate 5%.
Step-by-step explanation:
Caden ate 20%. Zoe ate 50% more than him, so 150% of 20%. That is 20+half of 20, which is 30. So zoe ate 30%. Noah ate 50% more than her, so 150% of 30%, which is 45%. Add them together and get 95%. That leaves 5% for Sophia to eat.
An envelope measures 9 inches by 4 inches. A pencil is placed at a diagonal. What is the maximum possible length of the pencil? If necessary round to the nearest tenth
Answer:
d = 9.84 m
Step-by-step explanation:
The dimensions of an envelope are 9 inches by 4 inches.
We need to find the maximum possible length of the pencil.
Let it be d. It can be calculated using Pythagoras theorem such that,
[tex]d=\sqrt{9^2+4^2} \\\\d=9.84\ m[/tex]
So, the maximum possible length of the pencil is 9.84 m./

Would give more pts if i had them
Answer:
1) They forgot to multiply 2 times (2x+5)
2) x-2 is not equal to -(x+2).
3) The correct expression is [tex]x-1-1+2x=1-3x[/tex]
4) The correct way is [tex]4(2x+3)=3(1-3x)[/tex]
Step-by-step explanation:
1) In this case they forgot to multiply 2 times (2x+5). Let's recall we need to multiply (2x+5) to all terms of the equation.
2) Here, x-2 is not equal to -(x+2). If we see -(x+2) = -x-2 using the distributive property.
3) After multiplying by (3x-2) we will have:
[tex]x-1-(1-2x)=1-3x[/tex]
Apply the distributive property again, we will have:
[tex]x-1-1+2x=1-3x[/tex]
So the correct term is 2x not -2x.
4) When we multiply by (1-3x)(2x+3) on each side of the equation, we will have something like this:
[tex]\frac{4(1-3x)(2x+3)}{(1-3x)}=\frac{3(1-3x)(2x+3)}{(2x+3)}[/tex]
If we see we can simplify the same terms on each side of the equation.
[tex]4(2x+3)=3(1-3x)[/tex]
This is the correct way to do this.
I hope it helps you!

Jeremiah paid $29.52 for a pair of boots that were on sale. The original price of the boots was 36.00 enter the percentage discount for the cost of the boots.
Answer: The percentage discount for the cost of the boots= 18 %
Step-by-step explanation:
Discount equals Price before Discount( original price ) − Price after Discount
=$36.00 −$29.52
=$6.48
Percentage discount = Discount / Price before Discount ( original price) X 100
= $6.48 / $36.00 x 100
= 0.18 x 100
= 18 %
