D: 18

Answer: 2

Step-by-step explanation:

Probability of not green: 1/2

0.5*4=2

Answer:

2 times

Step-by-step explanation:

The spinner is divided into 2 sections one being yellow, one being green. This implies a 1/2 or 50% chance of landing on yellow.

Spinning it 4 times means a 2/4 chance of landing on yellow, which is equal to 1/2. This means that the prediction is that you will land on yellow 2 out of the 4 total times

Answer:

1/5 or 20%

Step-by-step explanation:

Probability = favorable outcomes

                   total num. of outcomes

Probability =  2

                      10

Find the GCF, 2.

2 ÷ 2 = 1

10 ÷ 2 = 5

1/5

sorry if it's wrong

Answer:

The probability of choosing a green shirt is 20%=1/5=.2

Step-by-step explanation:

find the total amount = 10

Find the total of question (probability of choosing green) = 2

set as a fraction:

Numerator = amount needed (2)

Denominator = all things/objects involved (10)

PS*

With probability there is a good chance the answer is going to be less than 1 or 100%, knowing that can help to tell which number goes in what place of the fraction

ex:

10/2=5=500% (this can't be the answer)

So Flip it 2/10=.2=20% (This seems more of a reasonable answer)

Answer:

x1.5

Step-by-step explanation:

say x is 1 then is we multiply by 2 we get 2 and if we decrease 2 by 25% we get 1.5 and that number works for any number instead of multiplying by 2 and decreaseing by 25% as they reveal the same number.

Answer: ∠1 and ∠5

Step-by-step explanation:

You can see that all of the other angles are exactly 90 degrees. The remaining two are angles 1 and 5 which means that they have to be 90 degrees. Since they are together, they also look perfectly like a 90 degree angle.

Answer:

Answer is 40

Step-by-step explanation:

literally all you have to do is subtract 70 - 30 = 40

so your answer would be 40 another way is 30 + 40 = 70

just have to see what number would get you to 70 if you did the problem the second way.

Step-by-step explanation:

area is length multiply width 21 and 27 is 567m2

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Answer:

10cm

Step-by-step explanation:

If you want to find one of the heights of the triangle, you need to use some math magic. The magic spell is:

A = (1/2) * b * h

where A is the area, b is the base, and h is the height. Don't ask me why, it just works.

Now, we know that the area of triangle ABD is 50 cm and one of its sides is 10 cm. We can pretend that this side is the base of the triangle. Why? Because it makes our life easier. Trust me.

Then we put these numbers into the magic spell and we get:

50 = (1/2) * 10 * h

Now we need to solve for h, which is the height we want. To do that, we need to do some algebra. Don't worry, it's not that hard. Just follow these steps:

- Multiply both sides by 2. This gives us:

100 = 10 * h

- Divide both sides by 10. This gives us:

10 = h

- Celebrate! We found the height!

So, one of the heights of the triangle is 10 cm. Isn't math fun?

Answer: Formula for calculating the height of a cylinder:

V=πr^2h

Step-by-step explanation:

If you were given the volume and the radius then the formula you would use is V=πr^2h.

For example lets say your volume was 602.88 and your radius was 4.

To solve you would simply plug in your values.

602.88=π(4)^2h

since π is the equivalent to 3.14 your equation will now look like:

602.88=(3.14)(4)^2h

Then you begin solving!

602.88=(3.14)(16)h

602.88=50.24h

h=12

Step-by-step explanation:

Finding the area of the canvas:

The canvas has sides measuring 3x - 3 and 4x + 1 inches. To find the area, we multiply the lengths of the sides. So, the area of the canvas is given by:

Area = (3x - 3) * (4x + 1)

= 12x^2 + x - 3

Therefore, the correct equation for the area of the canvas is A = 12x^2 + x - 3.

Finding the area of the circle created by the paint:

The rate at which the paint is spreading on the canvas is given by the function r(t) = 4t, where t represents time in minutes and r represents how far the paint has spread. The area of the circle created by the paint can be expressed as A[r(t)] = πr^2, where r(t) is the distance the paint has spread at time t.

Substituting the value of r(t) = 4t into the formula, we get:

A[r(t)] = π(4t)^2

= 16πt^2

Therefore, the area of the circle created by the paint is 16πt^2.

Determining if the circle will be at least 1300 in² in 5 minutes:

To check if the area of the circle will be at least 1300 in² in 5 minutes, we substitute t = 5 into the equation for the area:

A[r(5)] = 16π(5)^2

= 400π

Approximating the value of 400π, we get approximately, 1256.64.

Since 1256.64 is less than 1300, we can conclude that the area of the circle created by the paint after 5 minutes will not be at least 1300 in².

When comparing the data, a measure of variability which should be used for both sets of data to determine the location with the most consistent temperature is: C. Range, because Sunny Town is skewed.

In Mathematics, skewness can be defined as a measure of the asymmetry of a box plot (box-and-whisker plot) or histogram and as such, a box plot (box-and-whisker plot) or histogram has a normal distribution when it is symmetrical.

By critically observing the box plot (box-and-whisker plot) which represent Sunny Town, we can logically deduce that it is skewed.

On the other hand (conversely), the box plot (box-and-whisker plot) for Desert Landing is symmetrical (vertical line dividing the box into two equal halves), which simply means that both whiskers on either sides of the box plot (box-and-whisker plot) are relatively equal and symmetric.

the formula to find volume= width x height x length ( or area x length)

Step-by-step explanation:

of A

of B

length of whole prism= 4

Volume (A)= w x h x l

                 =  5 x 9 x 4

                = 180 cm³

volume (B)= w x h x l

                = 3 x 2 x 4

                = 24 cm³

add both values to get the volume of whole prism = 180 + 24

                                                                                    = 204 cm³
