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
50 mph
Step-by-step explanation:
3(s-10)=2(s+10)
3s-30=2s+20
s=50

(PLEASE HELP, BRAINLIEST IF CORRECT) A jar is filled with quarters and nickels in the ratio 1 2/5 to 2 1/3. If there are 24 quarters in the jar, what is the ratio in dollar value of quarters to that of the nickels???
Answer:
40 nickels
Step-by-step explanation:
1 2/5 to 2 1/3 = 7/5 : 7/3
= 21/15 : 35/15
21/15 = 24
35/15 = x
(35/15 * 24) / 21/15

Max is scuba diving at an elevation of −64.5 feet when his friend signals to come higher. Max makes two ascents, each an equal distance, to reach an elevation of −21.4 feet, where his friend is located. What was Max's elevation after his first ascent? Enter your answer as a decimal in the box.
Answer:
-42.95ft
Step-by-step explanation:
First, find the change in elevation between where Max starts and where his friends are:
-21.4ft-(-64.5ft)=43.1ft
Since we're told that he makes two equidistant ascents, we know that each ascent would be equal to:
43.1ft/2=21.55ft
Now we take the height that he started at and add the height that he would gain in his first ascent
-64.5ft+21.55ft=42.95ft
What is 125 ÷ (2×7) = ???
Answer:
8.93
Step-by-step explanation:
Answer:
the answer is 8 and 13/14, or 8.93
Step-by-step explanation:
because of PEMDAS, we solve the numbers in the parenthesis first.
2 x 7 = 14.
next, we divide 125 by 14. 125 / 14 = 8 and 13/14
in decimal form, that is 8.93 (rounded up)

Meg is a veterinarian. She found that 5 or, 50% of the dogs she saw this week were boxers. Steve is also a veterinarian. He found that 50% out of the 2 dogs he saw this week were boxers. Does each person need to find the part, the whole, or the percent?
Question content area bottom
Part 1
Meg needs to find the
▼
percent.
part.
whole.
Part 2
Steve needs to find the
▼
percent.
part.
whole.
Answer:
a. Meg needs to find the part
b. Steve needs to find the percent.
Step-by-step explanation:
A. Does Meg need to find the part, the whole, or the percent.
Meg already knows the whole and the percent.
The whole is the entire number of dogs seen: 16 dogs.
The percent is 50%.
Hence, she needs to find the part: this is how many (what part) of the 16 dogs she saw were boxers.
And she can do with a simple operation:
Part = whole × percent = 16 × 50% = 8. This is 8 dogs of 16 were boxers.
B. Does Steve need to find the part, the whole, or the percent.
He already knows the part (7 of the 35 dogs were boxers) and the whole (35 dogs).
Then he needs to find the percent, which he can do using the next operation:
Percent = (part / whole) × 100 = (7/35)×100 = 20%
Step-by-step explanation:
Part 1:
Meg needs to find the whole as 50% of the dogs = 5 therefore 100% equals 10 dogs.
Part 2:
Steve saw 50% out of two dogs meaning that he only saw 1 dog that is a boxer.
