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
a big bag contains 500 beads, each of the same size, but in 5 different colors. Suppose there are 100 beads of each color and I am blindfolded. What is the fewest number of beads I must pick to be absolutely sure there are 5 beads of the same color among the beads I have picked blindfolded?
I WILL REPORT ANY FAKE OR USELESS ANSWERS
Answer:
I believe the answer is (4 * 5 +1) = 21
Step-by-step explanation:
The fewest number of beads you must pick to be absolutely sure there are 5 beads of the same color is 20 + 5 = 25 beads.
How to determine the fewest number of beads I must pick to be absolutely sure there are 5 beads of the same colorTo guarantee that you have picked 5 beads of the same color, you need to ensure that you have at least 4 beads from each of the 5 colors.
To calculate the fewest number of beads you must pick, we can consider the worst-case scenario where you have picked the maximum number of beads from each color without having 5 of the same color.
In this scenario, you would have 4 beads from each color, which totals 4 * 5 = 20 beads.
However, to guarantee that you have 5 beads of the same color, you need to pick one more bead from each color, which is an additional 5 beads.
Therefore, the fewest number of beads you must pick to be absolutely sure there are 5 beads of the same color is 20 + 5 = 25 beads.

Sam’s discount shoes is have a 40 percent off sale. A — use the percent ruler at right to find how much Lorna will save on her purchase of 80 dollar professional basketball shoes. B What will she pay for the shoes?
Answer:
A, 32
B, 48
Step-by-step explanation:
Since the discount is 40% off, she will save 40% of the 80 dollar shoes, which is 40% of 80 dollars. 40 * 80 = 3200, and 3200/100 = 32 dollars worth of savings. She will pay a total of 80 dollars minus the 32 dollar discount to get a total of 48 dollar payment.
Answer:
40% off that means her shoes will be 60% of the value so 80* 0.6 or 60% = $48 she will pay and 32 she will save
