Answer:
The perimeter is 44. Because we know the midpoints and distance between the sides of XR is half the side and YS is half the other side, those sides are 10 and 14. QS is a full side already so it is just 20. 20+14+10=44 for the perimeter.
Number 2 makes no sense, you've omitted something needed there.
Step-by-step explanation:
Answer:
15% off
Step-by-step explanation:
We know we paid $25.50 of the original $30. We can divide these two numbers 
. This is means we paid 85% of the original price. The discount percentage is the remaining percentage from 85 to 100 which is 15. The pants were 15% off.
Answer:
Step-by-step explanation:
A(7,1), B(5,-6)
(AB)² = (-6-1)² + (5-7)² = 53
AB = √53
Answer:
No
Step-by-step explanation:
A 5x8 matrix 
represents a linear transformation between the vector space 
and 
. Remeber that the columns of generate the image of the linear transformation, which is a vector subspace of . Therefore, 
, which is the dimension of the the total space.
So the formula is 2pi(r)(h)+2(pi)(r^2)
2(3.14)(40)(17)+2(pi)(40^2)
so then multiply and add it up and you get
about 14,325 1/3 or 14,325.34
