The answer would be 42 because its the same angle as the other one
I hope I helped! ♥
Answer:
8 weeks of piano lessons in order to play 16 pieces
rate of 2:1
Step-by-step explanation:
14/7 is 2
16 divided by 2 is 8
for every two weeks, one piece is learned

Answer: orthogonal </h3>
===========================================================
Explanation:
For any two vectors defined as follows
u = <a,b>
v = <c,d>
the dot product is computed by
u dot v = a*c + b*d
If the dot product of the vectors is 0, then the vectors are orthogonal. Meaning they are perpendicular to one another.
-------------------
Let's find the dot product of these two given vectors
u = < 2, -4 >
v = < 6, 3 >
u dot v = 2*6 + (-4)*3
u dot v = 12 - 12
u dot v = 0
Therefore, these two vectors form a right angle and are <u>orthogonal</u>
-------------------
Extra info:
If we can show that u = <a, b> and v = <ka, kb> for some real number k, then we have shown that vectors u and v are parallel.
it would depend how much you actually used, but you would take the amount you used and divide it by the total amount of yarn. so if the yarn was 4m long and you used 2m then it would be 2/4 which is 0.5 which is also 50%, so half the yarn was used.
Answer: 70 miles
Step-by-step explanation: scince the trip is 30% finished and that 30% was 21 miles you just have to multiply 21 by 3 which is 63and than you have to figure out what 1 third of 21 is which is 7 and than you just have to add 7 to 63. Hope this helps
