Two cars are traveling down the highway at the same speed. If the first car increases its speed by 10 kilometers per hour, and the second car decreases its speed by 10 kilometers per hour, then the first car will travel the same distance in two hours that the second car travels in three hours. What is the original speed of the cars?
Answer:
50mph
Step-by-step explanation:
Say for example car A increases by 10 miles per hour and car B decreases by 10 miles per hour. If car A2 = car B3 then by eliminating a few numbers and finally get to 50 you get the following equation.
A = 50+10
b = 50-10
A = 60
B = 40
A2 = 120
B3 = 120
120 = 120
Answer
120km
Step-by-step explanation:
let s = the original speed
Write a distance equation; dist = time * speed
3(s-10) = 2(s+10)
3s - 30 = 2s + 20
3s - 2s = 20 + 30
s = 50 km/hr is the original speed
confirm this, find the distances
3(50-10) = 120 km
2(50+10) = 120 km
which is shorter 8ft or 95in !?
Answer: 95 in is shorter
Step-by-step explanation:
there are 12 in in a foot, so in that case you have to divide 95 in by 12. The answer is 7.91666667 but if you round it up you would get 8, which that is = 8ft but without rounding it up you would get 7.9ft which is less than 8ft. so the answer is 95 in is shorter than 8ft

8. Multiply the following:
c. (3s^4)(-6s^5)
The result of the multiplication is (-18s^9).
To multiply the two expressions (3s^4)(-6s^5), you can use the distributive property, which states that you can multiply a term by each of the terms inside a set of parentheses.
Using the distributive property, you can rewrite the expression as:
(3s^4)(-6s^5) = 3s^4 * -6s^5
Then, you can simplify the expression by combining like terms:
3s^4 * -6s^5 = (-18s^9)
So the result of the multiplication is (-18s^9).

Answer:
The answer is C
Step-by-step explanation:
2 2/3 + 3 1/2
first, add the whole numbers
(2+3)+( 2/3+1/2)
=5 and then you multiply each fraction by the other denominators
2/3 x 2 and 1/2 x 3
=5 4/6 3/6
Now add each fraction because it is the same denominator
4+3=7 so it is 7/6 now to make it a mixed fraction
7/6=1 1/6
5 +1=6
6+1/6 = 6 1/6

Grant mows lawns for extra money. He mows 9 lawns in 9 hours on Wednesday and 6 lawns In 6 hours on Saturday.
What is the constant of proportionality that relates the total number of lawns mowed, y, to the number of hours mowing lawns, x?
It would be y=x or x=y as we can see that 9 lawns in 9 hrs equal 1 lawn in 1 hr. 6 lawns in 6 hrs equals to 1 lawn in 1 hr as well.

-----------
2.25
The simplest way to subtract 15 - 12.75 is (14 + 1) - (12 + 0.75) and it will be 2.25.
What is subtraction?To subtract in mathematics is to take something away from a group or a number of objects.
In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.
As per the given,
15 - 12.75
⇒ (14 + 1) - (12 + 0.75)
Open bracket
14 + 1 - 12 - 0.75
14 - 12 + 1 - 0.75
2 + 0.25 = 2.25

The price of a pair of headphones is $49.99 before tax. Ron bought the headphones for a 50% discount. He then paid sales tax of 8% on the discounted price.
Part A: How much did Ron pay in sales tax? Show all work and steps in your solution. (5 points)
Part B: What is the total amount that Ron paid for the headphones? Show all work and steps in your solution.
Answer:
A. $2.00
B. $26.99
Step-by-step explanation:
0.5 x 49.99 = 24.995
49.99 - 24.995 = 24.995
0.08 x 24.995 = 1.9996 and round to the nearest hundredth
24.995 + 1.9996 = 26.9946
round to the nearest hundredth
Answer:
Part a: 1.9996
Part b: 26.9946
Step-by-step explanation:
STEP 1:
Find the unit rate (1% of 49.99). You should get 0.4999. Then, multiply 0.4999 by 50. You should get 24.995.
STEP 2:
Find the unit rate of 24.995. You should get 0.24995. Then multiply 0.24995 by 8. You should get 1.9996 (answer for part a).
STEP 3:
Add 1.9996 to 24.995. You should get 26.9946 (answer to part b).
