why do you use denominator of 100 when you write a percent as a fraction?

Answers

Answer 1

Answer:

A percentage or percent for short is a fraction; a fraction that always has the denominator as 100. Because the denominator of a percent is always a 100, no matter what the numerator is, we replace 100 with the percent symbol % after the number.

Answer:

Nonlinear, linear, nonlinear(Please excuse my grammar)

Step-by-step explanation:

A is nonlinear because it is an exponential function. As we add more X inputs, the change is the Y coordinates increase by a greater and greater amount. As an example, X=1, then Y=3, X=2, then Y=9, etc. B is linear because it is a horizontal line. No matter the X input, Y will remain the same because it is given: y=-5. C is nonlinear because it is a quadratic function. In any quadratic function, the line reaches a vertex before changing directions therefore, not forming a line.

Find the surface area of the prism.

Answers

total surface area is: 416 m^2
740 square meters

First you do 16 times 10 for the base(the square on the bottom), this equals 160.
Then you do 17 times 10 for sides. We have two of these so just add 170 plus 170 which equals 340.
Next use the formula A=bh/2 for the triangle. A=16(15)/2 this equals 240 but since we have two triangles then we don’t have to divide it.
Then add all of your numbers which are 240+160+340 and you get 740.

What is Arithmetic?

The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations. The term "arithmetic" (which comes from the Greek word "arithmos," "number") often refers to the fundamental concepts in number theory, measurement, and computation (that is, the processes of addition, subtraction, multiplication, division, raising to powers, and extraction of roots).

As per the given data:

We have to find the expression which represents 6 times one fifth the sum of 13 and 7.

Let's say the expression is x.

x = 6 × one fifth the sum of 13 and 7

x = 6 × (1/5) × the sum of 13 and 7

x = 6 × (1/5) × (13 + 7)

Hence, the expression is one fifth x (13 + 7) x 6.
