So 3/4 × 2/3 = 17/12 because you take 3/4 and put = and see what 3 and 4 least common denominator and then the same with 2/3. Then from 3/4 I got 9/12 and 2/3 I got 8/12 then I added that and got 17/12, but then times 2 so I did 2/1 × 17/12 and got 34/12 and simplify and it would be 17/6 or 17/12.
First number = x
Consecutive number = x+1
"squares differ by 31" means to square both numbers and subtract them:
(x+1)^2 - (x)^2 = 31
x^2+2x+1 - x^2 = 31
2x+1 = 31
2x = 30
x = 15 (first number)
x+1 = 15+1 = 16 (consecutive number)
Answer: A) 1, 2, 4
Step-by-step explanation:
The range of a function is every y value.
Hi there --
If a plane can climb 2,400 feet per minute, it will need 25 minutes to reach 60,000 feet. // By dividing 60,000 (the needed feet) by 2,400 (the amount of feet the plane can climb per/min) you get 25 (the amount of mins needed to climb 60,000 feet)
Hope this helps! Have a great day! :)
Answer: The probability for both is 1/2
Step-by-step explanation:
For A. The probability for who do or do not participate in some kind of sport is found by adding the students who do or do not. Which is 25 + 225 = 250
250 out of 500 simplified is 1/2
For B. The probability got who do and do not participate in some kind of sport is found by taking the number of students out of the whole number. Its 250 out of 500.
250 out of 500 is simplified to 1/2.
