If ~v = hv1, v2, v3i and ~w = hw1, w2, w3i are vectors and c is a scalar, then
(a) c~v = hcv1, cv2, cv3i
(b) ~v + ~w = hv1 + w1, v2 + w2, v3 + w3i
(c) ~v − ~w = hv1 − w1, v2 − w2, v3 − w3i.
Answer:
She will cycle 85.169 miles in the third week.
(round if needed)
Step-by-step explanation:
56÷100=0.56 (this is 1%)
0.56 x 15 + 56 = 64.4 (you find 15% then add 56 (the original amount) because it's an increase of 15%)
repeat for the other 3 weeks
64.4÷100=0.644
0.644 x 15 + 64.4 = 74.06
74.06÷100=0.7406
0.7406 x 15 + 74.06 = 85.169
I know that 20% is out of 100.If I changed this problem to be a fraction problem,I would change that percent to 20/100.55 would be the denominater of the other fraction.Right now we're trying to find the numerator for the denominator of 55 to make this a complete fraction.Secondly,I would try to find a common denominator to get my answer.I'm going to make the common denominator......5500.As my teacher always said what you do to the bottom you do to the top and it goes the other way around too.So, i will times 20*55 to get my numerator.This equals 1100.Now I would divide this fraction by 100 to get my finished answer.The answer is 11 is 20% of 50.
Answer:
4 + 2.5c = 16
Step-by-step explanation:
Let c = number of candy bars
All soda cost $4.00
Each candy bar costs $2.50, so c number of candy bars cost 2.5c.
The total cost is the sum of the costs of the soda and candy bars.
Total cost is 4 + 2.5c
To write the equation we set the total cost expression above equal to the given total cost.
4 + 2.5c = 16
Answer:
54
Step-by-step explanation:
x is half the difference of the two arcs:
x = (136 -28)/2 = 54
The value of x is 54.
