Answer:

3 terms

Step-by-step explanation:

In this problem, we are given an expression of a quadratic function of a single variable x as x² - 3x + 7.

Now, we have to find the number of terms included in the above-given expression.

The expression includes two x terms and one constant term.

Therefore, the whole expression has total ( 2 + 1 ) = 3 terms. (Answer)

A package of floor tiles contains 24 one foot tiles. Find how many packages should be bought to cover a square ballroom floor wh

Gekata [30.6K]

Answer:

To cover a square ballroom 171 packages of tiles are required.

Step-by-step explanation:

Given:

1 package = 24 tiles.

Size of tile = 1 foot

Tiles are in square shape.

Hence Area of Tile = $side^2 =1^2 = 1 ft^2$

Also Given:

Side of the ballroom = 64 feet.

Ballroom floor is in square shape.

Hence we will find the Area of ballroom.

Area of ballroom = $side^2$

Are of ballroom = $64^2= 4096$

Now we will find the Number of tiles required to cover ballroom.

Number of tiles required is equal to Area of ballroom divided by Area of Tile.

Framing in equation form we get;

Number of tiles required = $\frac{4096}{1} =4096$

Now Given that

1 package contains = 24 tiles

Number of packages required = 4096 tiles

By using Unitary method we get;

Number of packages required = $\frac{4096}{24} = 170.67 \approx171$

Hence To cover a square ballroom 171 packages of tiles are required.

Subtract 5 from me then add 2. If you subtract 10 and then add 3, you get 15. What number am I

pshichka [43]

Answer:

You are 25

Step-by-step explanation:

This problem is a word problem that requires algebra notation, actually, we are meant to convert this word problem to mathematical expression then solve.

We proceed in a stepwise manner

let say what I have is x

1. Subtract 5 from me

(x-5)

2. Then add 2

(x-5)+2

3. If you subtract 10

(x-5)+2-10

4. And then add 3

(x-5)+2-10+3

5. you get 15

(x-5)+2-10+3=15

what am I is the question we need to answer, we do this by solving for x

x-5+2-10+3=15

x-15+5=15

x-10=15

x=15+10

x=25

(Picture) INFINITE SEQUENCES AND SERIES PLEASE HELP!!

mojhsa [17]

Answer:

C) $x=\frac{17}{33}$

Step-by-step explanation:

0.51 repeating decimal

x= 0.51515151

multiply by 100 on both sides

100x = 51.515151.........

x= 0.515151...............

--------------------------------------------(subtract)

99x = 51

divide by 99 on both sides

$x=\frac{51}{99}$

divide both sides by 3

$x=\frac{17}{33}$
