Ok, so in order to get tax on something you multiply the amount by the amount of tax in decimal form and then add back the original amount. So for this, you'd start with 8.64*0.07, which equals 0.6048. This rounds to 0.60. 8.64+0.60=9.24
So, he would owe $9.24 total.
-5 because -5 plus 42 equals 37
Answer:
Step-by-step explanation:
f(x)=x²-5x+7
f(2)=2²-5.2+7=4-10+7=11-10=1
f(-1)=(-1)²-5.(-1)+7=1+5+7=13
f(1/3)=(1/3)²-5(1/3)+7=1/9-5/3+7=49/9
∴, f(2)-f(-1)+f(1/3)
=1-13+49/9
=58/9-13
=-59/9

Answer:
107/18
Step-by-step explanation:
Your calculator and/or knowledge of trig function values can help you evaluate this.
= 4/3(1/3) +3/4 -3(3/4) +3(3) -2(1)
= 4/9 +3/4 -9/4 +9 -2
= 107/18
___
tan(30°) = 1/√3
tan(45°) = 1
tan(60°) = √3
sin(60°) = cos(30°) = √3/2
Answer: 376 cm^2
Step-by-step explanation:
First you would double all the dimensions:
l = 5 cm x 2 = 10 cm
w = 4 cm x 2 = 8 cm
h = 3 cm x 2 = 6 cm
The formula for finding the surface area of a rectangular prism is A=2(wl+hl+hw)
Substitute the values:
A=2(8*10+6*10+6*8)
Solve using PEMDAS:
A=2(80+60+48)
A=2(188)
A=376
Surface area is always in units^2:
376 cm^2
