Hello!
Sales tax is basically additional money added onto your purchase, which means we must find the sales tax and then add that onto the cost of the shoes.
To find the sales tax, we multiply the cost of the shoes by the percentage of tax applied to the purchase.

45 + 2.925 = 47.925
Round this to 47.93
So, the shopper pair $47.93 in all.
Answer:
80 square m
Step-by-step explanation:
We are given that
Mean=150 m
S.D=4 m
We have to find the variance of the total length of the wire in the coils.
Let X1, X2,X3,X4 and X5 are random variable of sample space of coil are choosing.
Var for all i=1 to 5
Let X be the total length of coils
Hence, the variance of the total length of the wire in the coils=80 square m
The ratio 1: 3 means there is 1 red one and 3 blue ones.
For the ratio 3:1 there needs to be 3 red for every one blue.
You have 3 blue ones, so you would need 3 x 3 = 9 red ones.
You already have 1 red one so you would need 8 more.
Answer:
Step-by-step explanation:
A and B are along a straight line
(3x - 20) + 2x = 180
5x = 200
x = 40
3(40) - 20 = 100°
