What is the sum of 3/4 and 18/19 closest to 0 1 or

Answers

Answer 1
Answer: to solve this, you must find a common denominator (the number on the bottom of the fraction) before adding the numbers. The easiest was to do this is multiply the denominators together to get a common product. You then multiply by that number over itself, because that is equivalent to 1. So in this problem, you would multiply 3/4 by 19/19 and 18/19 by 4/4. Once you do this, you can add the fractions together.

Answers

a² - ab + 8b + b² - 1

There are 5 terms in the expression. 
a² = 1st term
ab = 2nd term
8b = 3rd term
b² = 4th term
1 = 5th term

Each term is separated by a plus (+) sign or a minus (-) sign.

A term is either a number, a variable, or a number and a variable multiplied together.

a², ab, b² are variables.
8b is a number and a variable multiplied together
1 is a number.

Step-by-step explanation:

Solve i=Prt for t, if i=105, P=700, and r=0.05

Answers

plug i=105, P=700, r=0.05 in the equation i=Prt
105 = 700*0.05*t
105 = 35*t
divide both sides by 35 
105/35 = 35*t/35
3 = t 
t = 3

Explain why the following triangle cannot exist. Note that no angle measure are known.

Answers

The triangle does not exist because the sum of the lengths of any two sides of a triangle is greater than the length of the third side.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

In the given triangle the smaller sides are 8 and 17.

The larger side length is 26.

The sum of the two sides of a triangle must be greater than the third side length to make the triangle exist.

8+17 is 25

25<26

Hence, the triangle does not exist because the sum of the lengths of any two sides of a triangle is greater than the length of the third side.

What is the total surface area of a right circular cylinder with base radius 7cm and height 12cm.

Answers

Answer:

Using 3.14  for pi

835.24 cm^2

Using the pi button for pi

835.6636459 cm^2

Step-by-step explanation:

The surface area of a cylinder is given by

SA = 2 pi r^2 + 2 pi r h

     = 2 * pi ( 7)^2 + 2 pi ( 7) * 12

    = 98 pi + 168 pi

    =266 pi

Using 3.14  for pi

835.24 cm^2

Using the pi button for pi

835.6636459 cm^2

Answer:

226\pi or 835.664

Step-by-step explanation:

Surface area of a right cylinder= 2πrh+2πr^2

=2π7✖️12+2π49

=226π
