math

Tiled floor with 225 square tiles means the area of the square room is 225.

Formula needed: A = (side)^2 or in short

A = s^2.

We need to find s.

225 = r^2

sqrt{225} = sqrt{r^2}

15 = r

There are 15 tiles are along an edge of the room.

Answer:

There may not be an image representation of this question but I can probably answer this. If the smaller wheel causes the the bigger wheel to rotate, the wheel will rotate 30.0° about everytime. this only depends on the speed of the smaller wheel.

Answer:

0.7727 = 77.27% probability that it is small or green

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

11 large + 11 small = 22 total marbles = 22 total outcomes

11 small marbles  + 6 green large marbles = 17 desired outcomes.

What is the probability that it is small or green?

[tex]p = \frac{17}{22} = 0.7727[/tex]

0.7727 = 77.27% probability that it is small or green

Answer:

x= 43, y=215

Step-by-step explanation:

Let one number be x,

Let the other number be y.

x= 5y

x - y= 172

Putting value of x in equation 2.

5y - y = 172

4y = 172

y= 172/4

y= 43

Putting value of y in eq. 1

x= 5(43)

x=215.

Answer:

The correct answer is C. 160 minutes.

Step-by-step explanation:

Since Tammy has begun an exercise program, and she worked out five days the first week for 28 minutes, 32 minutes, 21 minutes, 38 minutes and 42 minutes, to find an estimate of the total number of minutes Tammy exercised during the week, rounding each figure to the nearest tenth, the following calculation must be performed:

28 + 32 + 21 + 38 + 42 = X

30 + 30 + 20 + 40 + 40 = X

160 = X

Thus, the estimated time of exercise that Tammy performed was 160 minutes.

Answer:

30

Step-by-step explanation:

Again there are TWO sides so it would be 50% chance of getting head, or 50% of getting tail. So it would probably be 30

Answer:

"50% of the time"

Step-by-step explanation:

Because the probability is limited to only 2 sides you have a 50% chance it will land on either heads, or tails.

Step-by-step explanation: The math is common sense

You can tell if 3 side lengths will form a triangle if you know each length by adding all 3 side lengths together. If they equal a total of 180 degrees then it is a triangle.

9514 1404 393

Answer:

Step-by-step explanation:

Let b represent the base of the triangle in meters. Then the height is ...

  h = 3 +2b

and the area is ...

  A = 1/2bh

  8 = 1/2(b)(3 +2b)

  16 = 3b +2b^2 . . . . . . . multiply by 2 and eliminate parentheses

  2(b^2 +3/2b + (9/16)) = 16 + 9/8 . . . . . . complete the square

  2(b +3/4)^2 = 17.125

  (b +3/4)^2 = 8.5625 . . . . . divide by 2

  b + 0.75 = √8.5625 ≈ 2.9262

  b = -0.75 +2.9262 = 2.1762

  h = 3 +2b = 7.3523

The base is about 2.18 meters and the height is about 7.35 meters.

Answer:

Using the formula for Area of circle_

πr²

putting values_

π = 3.14

r² = (5)² = 25.

Therefore,

3.14 × 25

Answer:

y = 23

x = -4.5

Step-by-step explanation:

Given:

Equation

8x + y = -13 ......eq1

8x + 2y = 10​........eq2

Find:

Solution

Computation:

Eq2 - Eq1

y = 23

From eq1

8x + y = -13

8x + 23 = -13

8x = -36

x = -4.5

Use the given functions to set up and simplify  f ( − 3 ) .

Answer:

y=16 bc 17 -16 =1 which if u do backward equals the same thing

and all together is

18y+1 and just leave it like that dont touch the numbers or anything bc you cant take a 1 and join it with a variable

you can only join numbers with numbers and variables with variables

Answer:

We have 4 triangles with base 3 and height 4 and a square with side length 3 so:

Triangles:

The area for a triangle is calculated by [tex]\frac{bh}{2}[/tex] where b is the base and h is the height so we have [tex]\frac{12}{2}\cdot 4[/tex] so we have a total area of 24.

[b]Square:[/b]

The area of a square is calculated by [tex]s^{2}[/tex] where s is the side length so we have the area is 9.

Now we put them together for the surface area so we get 24 + 9 = [tex]\boxed{33}[/tex]

Answer:

[tex]T_7 = \frac{64}{729}[/tex]

Step-by-step explanation:

Given

[tex]a =1[/tex]

[tex]r = \frac{2}{3}[/tex]

Required

Determine the 7th term

The nth term of a gp is:

[tex]T_n = a * r^{n-1[/tex]

So, we have:

[tex]T_7 = 1 * \frac{2}{3}^{7-1[/tex]

[tex]T_7 = 1 * \frac{2}{3}^{6[/tex]

[tex]T_7 = 1 * \frac{2^6}{3^6}[/tex]

[tex]T_7 = 1 * \frac{64}{729}[/tex]

[tex]T_7 = \frac{64}{729}[/tex]

Answer:

6x + 7.50y ≥ 75

Step-by-step explanation:

Let x = # of hours he walks the dog

     y = # of hours he washes cars

We also know that he cannot have any negative hours, so 2 lines that we need to graph will be y = 0, with everything above this line shaded in, and x = 0, with everything to the right of this line shaded in and these lines will be solid because you can have 0 hours.

Another equation will be x + y ≤ 15. We graph the line, which will be solid, y = -x + 15, and shade everything to the left of this line.

The last equation will be 6x + 7.50y ≥ 75. We graph this solid line, y ≥ (-6x + 75)/7.50 & shade everything to the right of this line. Any point inside the area shaded in by all 4 equations will be an answer. I'll leave this up to you.

Hope this helps!
