Answer:
Option C)
Step-by-step explanation:
We are given the following in the question:
I is the annual income of a person in a country R
2 percent of one’s annual income =

1 percent of one’s annual income =

Average of 100 units of Country R’s currency and 1 percent of one’s annual income.

Income tax =
2 percent of one’s annual income + Average of 100 units of Country R’s currency and 1 percent of one’s annual income.

Thus, income tax is given by
Option C)

Answer:
7√(x) = 14
Step-by-step explanation:
The composite shape is made up of a cube with a side length of 5 inches and a cylinder with a radius of 2 inches and a height of 4 inches.
The composite solid's surface area is 225.4 square inches.
Step-by-step explanation:
Step 1:
The given composite shape is made up of a cube with a side length of 5 inches and a cylinder with a radius of 2 inches and a height of 4 inches.
The surface area of the composite shape is given by summing the individual surface areas.
The composite shape's surface area = The cube's surface area + the cylinder's surface area.
Step 2:
Any cube's surface area is calculated by multiplying 6 with the square of the side length (
).
The cube's surface area =
=
=
square inches.
Step 3:
Any cylinder's surface area is calculated with the following formula;
The cylinder's surface area =
=
=
square inches
Step 4:
The composite shape's surface area = The cube's surface area + the cylinder's surface area.
The composite shape's surface area = 150 + 75.398 = 225.398 square inches. Rounding this off, we get the area as 225.4 square inches.
Significant digits are all digits, after the comma, excluding the first if this first is Zero
So the number of significant digits is 3 (1,0,2)
