Answer: What
Step-by-step explanation:
The system of equations relates the distance, y,
from a station of two trains and the speed, x, at which they are moving.
y + 10x = 250
2.5y = -25x + 625
a. What does the system of equations tell you about the speed
of the trains?
b. What does the solution tell about the locations of the trains if they
left the station at the same time? If they left at different times?
Answer:
a . It is a simultaneous speed.
Imma just do it again cause why not lol

UGH! RSM!!!!!!!!!!!!!!!!!!!!! John's family visited his grandmother over the weekend. The drive to her house took 2 hours at their usual speed. the trip home took 15 minutes longer because traffic was bad and they had to drive 5 mph slower. How many miles away is john's grandmother's house? will give BRAINLIEST! +10pts!
Answer:
90 miles!
Step-by-step explanation:
there are two parts to the problem, meaning you'll need 2 equations.
let's call the distance TO the grandma's house d1, and BACK from the grandma's house d2.
KEY:
time TO g'ma house= t1
time FROM g'ma house=t2
(replace the t's with 's' for speed, with the '1' for to, and '2' for from)
(distance is a constant so d1 is always equal to d2).
-------------
d1=s1+t1, d2=s2+t2
we know what t1 is. 2 hours.
d1=s1•2
meaning that d2 is also equal to that.
s1•2=(s1-5)•2 1/4
2s1=2 1/4 s1-11 1/4
11 1/4= 2 1/4 s1-2s1
11 1/4 = 1/4 s1
s1 (to g'ma)=45 mph
distance is speed times time.
so 45•2 (hr) = 90.

Step-by-step explanation:
A car has 15 gallons of gas in its tank. The car travels 35 miles per gallon of gas. It uses 135 of a gallon of gas to go 1 mile. How much gas does it use to go 100 miles?
2.86 gallons
Step-by-step explanation:
If 1/35 gallon of gas = 1 mile
To travel 100 miles,
1/35 * 100
= 0.0286 * 100
= 2.86 gallons
Therefore, the car needs 2.86 gallons of gas to travel 100 miles

Answer:
2.73 8.75
Step-by-step explanation:
n = 1
1 (DOUBLE) = 1+1 = 2
2 +3/4 = 1.5
1.5 +2 = 3.5
3.5 x 0.22 = 0.77
3.5 - 0.77 = 2.73
n = 1
1 + 3/4 = 1 + 0.75 = 1.75
1.75 (DOUBLE) = 3.5
3.5 x 2 1/2 = 8.75

Solve the equation:
4=32b
b=_____
Look at the picture and answer the question: What is the length of QS?
Step-by-step explanation:
firstly draw the triangle and label it. (you will find the picture down)
Now this remind us with the cosine rule. (you will find the picture down)
This rule says that the square of the given length of the side of a triangle is equal to the sum of the squares of the length of other sides minus twice their product and multiplied by the cosine of their included angle.
So using that rule we can say that:
[tex]QS^{2}[/tex] = [tex]QR^{2} +SR^{2} - 2(QR)(SR)(cosR)[/tex]
square root both sides, so you will have QS alone in one side.
QS = [tex]\sqrt{ [QR^{2} +SR^{2} - 2(QR)(SR)(cosR)]}[/tex]
plug in the values we have and y=this will yield:
QS = [tex]\sqrt{ [11^{2} +16^{2} - 2(11)(16)(cos38)] }[/tex] = 9.98099267 = 10

Machine A makes 12.75 ounces of popcorn in 3 minutes. Machine B makes 18 ounces of popcorn in 4 minutes.
If each machine makes popcorn for 10 minutes, will there be enough popcorn for eight 9-ounce bags? Explain.
Answer:
yes if each machine makes popcorn for 10 minutes, there be enough popcorn for eight 9-ounce bags
Step-by-step explanation:
yes because 12.74 x 3.3 = 42.075 and 18 x 2.5 = 45 and when you add those together you get 87. Also 8 9-ounce bags = 72 and that is less then what you have.
Answer:
Yes there will be enough popcorn for eight 9-ounce bags.
Step-by-step explanation:
" eight 9-ounce bags"
Basically
"72 ounces"
"12.75 ounces of popcorn in 3 minutes"
Basically
We need to find out how much popcorn we can make in "One Minute"
12.75÷3=4.25
Now we need to find out how much it can make in "Ten Minutes"
4.25×10=42.5
"18 ounces of popcorn in 4 minutes."
Basically:
We wanna find out how much it can make in "One Minute"
18÷4=4.5
"makes popcorn for 10 minutes"
Basically:
We need to find out how much popcorn it can make in "Ten Minutes"
4.5×10=45
Add (45) and (42.5)
45+42.5=87.5
So yes,there will be enough popcorn for eight 9-ounce bangs due to the fact A and B makes (87.5) ounces of popcorn and thats greater than (72) ounces.
Answer option C is correct.

The Wagner school store is having a sale! At the sale this week, a life sized stuffed animal of Wagner’s mascot is being sold for $158.40. This is a 52% discount of the original price. What is the original price? If necessary, round to the nearest cent.
Divide the sale price by the percentage of the original cost.
Percent of original cost = 100% - 52% = 48 %
158.40 / 0.48 = 330.00
The original price was $330.00
