Answer:
Step-by-step explanation:
in a right triangle a^2+b^2=c^2,
where a and b are the legs
where c is the hypothenuse
9^2= b^2+3^2
81-9=b^2
b^2=72
b=8.48
Answer:
2m - 20
Step-by-step explanation:
Given that:
First week minutes = m
Second week minutes = (2 * first week minutes - 20)
Second week = 2m - 20
Therefore, the expression for the number of practice minutes for the second week is :
2m - 20
The answer is 12. I got it by dividing 2/3 into 8. I used keep change flip. First I made 8 a fraction by putting one as it's denominator. Then I changed division to multiplication. After that, I flipped the fraction from 2/3 to 3/2. Then I multiplied across. My answer was 24/2. I simplified and got my final answer of 12.
