Answer: A fraction where the denominator (the bottom number) is a power of ten (such as 10, 100, 1000, etc).

Hope this helps

Hope this helps

Answer: As an addition to the answer above I would like to include that for example if you are doing 43 x 100 in decimal fraction it would come to 0.43 I hoped this helped and that was an example.

Add these polynomials and simplify. Enter your response in standard form. (x4 − 9x + 5x7) + (5x − 10 + 3x4 − 2x2)

Tom simplify the given expression we proceed as follows:

(x^4 − 9x + 5x^7) + (5x − 10 + 3x^4 − 2x^2)

We open the parenthesis

x^4-9x+5x^7+5x-10+3x^4-2x^2

put like terms together:

x^4+3x^4-9x+5x+5x^7-10-2x^2

simplifying the above we get:

4x^4-4x+5x^7-10-2x^2

Thus can be rewritten in order of the highest degree as:

5x^7+4x^4-2x^2-4x-10

Answer: 5x^7+4x^4-2x^2-4x-10

(x^4 − 9x + 5x^7) + (5x − 10 + 3x^4 − 2x^2)

We open the parenthesis

x^4-9x+5x^7+5x-10+3x^4-2x^2

put like terms together:

x^4+3x^4-9x+5x+5x^7-10-2x^2

simplifying the above we get:

4x^4-4x+5x^7-10-2x^2

Thus can be rewritten in order of the highest degree as:

5x^7+4x^4-2x^2-4x-10

Answer: 5x^7+4x^4-2x^2-4x-10

Answer:

5x7 + 4x4 - 2x2 - 4x - 10

Step-by-step explanation:

To add both polynomials, there must be a rearrangement of the terms of both polynomials after removing he parenthesis. The rearrangement is such that items are group together based on the power of x. As such,

(x4 − 9x + 5x7) + (5x − 10 + 3x4 − 2x2)

= x4 − 9x + 5x7 + 5x − 10 + 3x4 − 2x2

Rearranging...

= 5x7 + x4 + 3x4 -2x2 - 9x + 5x - 10

simplifying,

= 5x7 + 4x4 - 2x2 - 4x - 10

Solve for h. -117 = -9h

H= 13

This is because -117/ -9 equals 13

This is because -117/ -9 equals 13

Answer:

H= 13

Step-by-step explanation:

You divide the -9 to get h by itself, but what you do to one side you do to the other. So you divide -117 by -9 and get 13.

A game room has a floor that is 175 feet by 30 feet. A scale drawing of the floor on grid paper uses a scale of 2 units:5 feet. What are the dimensions of the scale drawing? Enter your answer as length by width

Answer:

70 units by 12 units

Step-by-step explanation:

To find the drawing size, multiply the actual dimensions by the scale factor.

(175 ft) × (2 units)/(5 ft) = (175·2/5) units = 70 units

(30 ft) × (2 units)/(5 ft) = (30·2/5) units = 12 units

The drawing size is 70 units by 12 units.
