Answer:
Yes, the bill is absolutely accurate
Step-by-step explanation:
Cost of materials= $ 678.12
Final bill amount(given)=$1206.12
Rate= $32 per hour for 16.5 hrs
Total amount for 32 hrs = time * rate = 16.5* 32=$528
Therefore, by the problem ,
<em>Cost of materials+ Total amount for 32 hrs = Final bill amount</em>
= 678.12+ 528
=1206.12
<u>Therefore , the final bill amount is 100% accurate as it completely matches with the given bill amount</u>
Answer:
Let's simplify step-by-step.
34(5a−16)−13(6a−3)
Distribute:
=(34)(5a)+(34)(−16)+−2a+1
=154a+−12+−2a+1
Combine Like Terms:
=154a+−12+−2a+1
=(154a+−2a)+(−12+1)
=74a+−11
Answer:
=74a−11
Answer:
Sin^2 x + Cos^2 x = 1
Sin^2 x = 1 - 4 / 9 = 5 / 9
Sin x = / 3
Tan x = Sin x / Cos x = ( / 3) / (2 / 3) = / 2
Multiply the height by the base to get the area. 8 x 6 = 48. The area of the first triangle is 48 square inches. 8 x 10 = 80. The area of the second triangle is 80 square inches.
