Answer:
A is 840 I think and B is 2400
Step-by-step explanation:
so if u x 10x12=120x7=840. that's for A.
so for B is 15x10=150x10=2400
I'm pretty sure this should be right I hope you get a really good grade on this
5/6
Explanation:
This event happened 10 out of 12 times. We can put this as 10/12
We can simplify 10/12 to 5/6
Answer:
Not sure what you mean here, is this a table? If so, you need to provide the y value or a screenshot!
Answer:
x = sqrt(11 - y) - 2 or x = -sqrt(11 - y) - 2
Step-by-step explanation:
Solve for x:
y = -x^2 - 4 x + 7
y = -x^2 - 4 x + 7 is equivalent to -x^2 - 4 x + 7 = y:
-x^2 - 4 x + 7 = y
Multiply both sides by -1:
x^2 + 4 x - 7 = -y
Add 7 to both sides:
x^2 + 4 x = 7 - y
Add 4 to both sides:
x^2 + 4 x + 4 = 11 - y
Write the left hand side as a square:
(x + 2)^2 = 11 - y
Take the square root of both sides:
x + 2 = sqrt(11 - y) or x + 2 = -sqrt(11 - y)
Subtract 2 from both sides:
x = sqrt(11 - y) - 2 or x + 2 = -sqrt(11 - y)
Subtract 2 from both sides:
Answer: x = sqrt(11 - y) - 2 or x = -sqrt(11 - y) - 2
Answer:
George Bush received 286 votes and John Kerry received 251 votes.
Step-by-step explanation:
Total number of votes = 537
% of votes received by George Bush = 53.25 %
No. of votes recieved by George Bush = 
×537
= 285.95
≈ 286 votes.
The rest of the votes were for John Kerry,
=537 - 286
= 251
