C. $122.10
20 first hour
20+0.1*20 = 22 second hour
22+0.1*22 = 24.2 third hour
24.2+0.1*24.2 = 26.62 fourth hour
26.62+0.1*26.62 = 29.282 fifth hour
Total=$122.10
Answer:
63
Step-by-step explanation:
Follow PEMDAS, as well as the left -> right rule.
Note that PEMDAS is the order of operations in which you should solve, and =
Parenthesis
Exponents (& roots)
Multiplication
Division
Addition
Subtraction.
First, look at the problem. The problem gives you:
42 ÷ 2 x (11 - 8)
Using PEMDAS, first, solve the parenthesis:
11 - 8 = 3
Next, use the left -> right rule to solve the rest.
42 ÷ 2 x 3
(42 ÷ 2) x 3
(21) x 3 = 63
63 is your answer.

Answer:
-2.5
Step-by-step explanation:
Slope (m) =
ΔY
ΔX
=
-5
2
= -2.5
θ =
arctan( ΔY ) + 360°
ΔX
= 291.80140948635°
ΔX = 7 – 5 = 2
ΔY = -2 – 3 = -5
Distance (d) = √ΔX2 + ΔY2 = √29 = 5.3851648071345
Equation of the line:
y = -2.5x + 15.5
or
y =
- 5 x
2
+ 31
2
When x=0, y = 15.5
When y=0, x = 6.2
The amount of vitamin needed is the amount required to fill the 282.6 cubic millimeter of capsule's volume.
<u>Step-by-step explanation</u>:
The capsule is in the shape of a cylinder.
Step 1 :
Radius, r = 3 millimeter
Length or height, h = 10 millimeter
The amount of vitamin mix = Volume of the capsule (cylinder).
Step 2 :
Volume of the cylinder = πr^2h
= 3.14 3^2 10
= 3.14 9 10
= 282.6 cubic millimeter
∴ The amount of vitamin needed = amount required to fill the 282.6 cubic millimeter of capsule's volume.
