Answer:
The quotient rule means dividing
Step-by-step explanation:
"The quotient rule says that if we have exponents with the same base being divided, we can just subtract the exponents. Ultimately this is about <u>dividing</u> exponential expressions."
Answer:
Step-by-step explanation:
Since this is a test/homework, I'll give you a hint.
A triangle always is 180 degrees. If you add up all the sides, it should be 180.
A horizontal line is 180, if you add up the two sides (or the "line" that is crossing through the horizontal one) it'll be 180.
Just think of it like this: 180 is king. No matter what you add together, if its not 180, its wrong.
Hope this helps!
Answer:
9 12 15
Step-by-step explanation:
9²+12²=15²
81+144=225
Answer:
It is C. 233 because if you multiply 5x5x5 thats 125
If you multiply 12x3x3, its 108. So add 108+125 and that will be your final answer. Hope this helps and if so then please mark as brainliest. Remember that volume= length x width x height.
Answer for problem 46 is choice A
Answer for problem 47 is choice B
Answer for problem 48 is choice E

Work Shown
Problem 46
Equation 1: 3x+y = 17
Equation 2: x+3y = -1
Add equation 1 to equation 2 to get 4x+4y = 16. Divide every term by 4 to get x+y = 4. Then finally multiply both sides by 3 to get 3x+3y = 12
That shows why the answer is choice A
---------------------------------
Problem 47)
If y hours pass by, then y-(2/3)y=y/3 is the time value (2/3)y hours ago
So,
Distance = rate*time
d = r*t
d = x*(y/3)
d = (xy)/3
That's why the answer is choice B
---------------------------------
Problem 48)
Let L1,L2,L3 be the three lists where
L1 = {a1,a2,a3,...,ak} there are k scores here
L2 = {a1,a2,...,a10} there are 10 scores here
L3 = {a11,a12,...,ak} the remaining k-10 scores
S(L1) = sum of the scores in list L1
M(L1) = mean of L1 = 20 = S(L1)/k
M(L2) = mean of L2 = 15 = S(L2)/10
S(L1) = 20k
S(L2) = 150
S(L1) = S(L2)+S(L3)
M(L1) = [S(L2)+S(L3)]/k
20 = [150+S(L3)]/k
20k = 150+S(L3)
S(L3) = 20k-150
M(L3) = [S(L3)]/(k-10)
M(L3) = (20k-150)/(k-10)
So that shows why the answer is choice E
