1 answer:
OLEGan [10]3 years ago
8 0

Answer:

D) 67.4°

Step-by-step explanation:

by observation, and noting that triangle PQR is a right triangle

sin R = opposite length / hypotenuse

in our case, the hypotenuse is PR = 13 and the length opposite form R is QP = 12

hence

sin R = opposite length / hypotenuse

sin R = 12/13

R = sin⁻¹ (12/13) = 67.4⁰

Mr.McNeil bought two magazines for 7.45 and one book for 14.95. If the sales tax is 6% , what is the total cost of Mr.McNeil’s p
blagie [28]

Answer:

total cost = $22.4 + $1.12 = $23.52

Step-by-step explanation:

Mr McNeil bought 2 magazines for $7.45 and 1 book for $14.95 . The sales tax is 6% . The total cost of Mr McNeil can be calculated as follows.

He bought 2 magazines for $7.45  .This means the sum of the prize of the 2 magazine he bought is $7.45 and the prize for the single book he bought is $14.95.  The total cost of the items he bought excluding the sales tax is the sum of the whole items he bought.

total cost excluding sales tax = $7.45 + 14.95 = $22.4

The sales tax is 5% which can be calculated as follows

5/100 × 22.4 = 112/100 = $1.12

The total cost of Mr McNeil purchase including his sales tax is

total cost = $22.4 + $1.12 = $23.52
