The x-coordinate of the intersection point of the lines y=3x+5 and y=2x-7.
Answer: The answer is C
The vector (-7,-5) as a sum of unit vectors is -7i-5j
Answer:
1) 80%
2) 95%
3) 33 %
4) 15%
Step-by-step explanation:
1) 4 of 5 must be written as a percent over 100 so you divide,
5 ÷ 100 = 20 so 20 * 4 = 80% so the answer is 80%
2) 19 of 20 must be written as a percent over 100 so you divide,
19 ÷ 20 = 0.95 so the answer is 95%
3) 50 of 150 must be written as a percent over 100 so you divide,
50 ÷ 150 = 0.33 so the answer is 33 %
4) 6 of 40 must be written as a percent over 100 so you divide,
6 ÷ 40 = 0.15 so the answer is 15%
Well, first off, you see how all the answers say a fraction, then pi? that means that you don't calculate pi into your answer.
But lets see. The radius is 4. V=(4/3)pi*r^2
V=(4/3)pi*4^2
V=(4/3)pi*16
V=(4/3)*16*pi
V=(4/3)*(16/1)*pi
V=(4*16)/(3*1)*pi
V=64/3*pi
so the answer is (B) 64/3pi units cubed.
