Step-by-step explanation:

To find the diameter of a circle, you multiply the radius (the radius is the distance from the outside of the circle to the middle) by 2.

Ex: the first one has 6m as the radius. So you would multiply the 6 by 2. Which would be 12.

The radius is half of the diameter. So for number 8, the answer would be 2.

hope this helps and that it wasn't to confusing  :)

Answer:

x = 5

Step-by-step explanation:

Given

4(x - 2) = 12 ( divide both sides by 4 )

x - 2 = 3 ( add 2 to both sides )

x = 5

Answer:

Yes links are not good

Step-by-step explanation:

Answer:

a) 24 degrees

b) 50 degrees

Step-by-step explanation:

part a : use sine-1

sine-1 = [tex]\frac{opposite}{hypotenuse}[/tex]

sine-1 = [tex]\frac{17}{42}[/tex]

sine-1 = 0.405

missing angle = 23.89

round to the nearest degree = 23.89 = 24

part b : use cosine-1

cos-1 = [tex]\frac{adjacent}{hypotenuse}[/tex]

cos-1 = [tex]\frac{16}{25}[/tex]

cos-1 = 0.64

missing angle = 50.208

round to the nearest degree = 50.208 = 50

Answer:

It would be the first option.

Out of curiosity, what is making this problem difficult?

Step-by-step explanation:

initially there are 20 rabbits,  so the '?' is asking for that

Answer: 50%

Step-by-step explanation:

If we can get a head tails combo in any order we could get a head/tails or a tails/head so there is a 50% probability of getting that combo in a trial

Answer:

Domain: [tex][-1,\infty)[/tex]

Range: [tex](-\infty, 3][/tex]

Decreases over: [tex](-1,-\infty)[/tex]

Step-by-step explanation:

Given

[tex]f(x) = -\sqrt{x + 1} + 3[/tex] --- Missing from the question

Solving (a): The domain

To get the domain, the expression under the square root must not be negative.

In other words:

[tex]x + 1 \ge 0[/tex]

Solve for x

[tex]x + 1 -1\ge 0-1[/tex]

[tex]x \ge -1[/tex]

Hence, the domain is:

[tex][-1,\infty)[/tex]

To get the range, we plot the values of the domain in the expression.

[tex]x = -1[/tex]

[tex]f(x) = -\sqrt{x + 1} + 3[/tex]

[tex]f(-1) = -\sqrt{-1+1} +3[/tex]

[tex]f(-1) = -\sqrt{0} +3[/tex]

[tex]f(-1) = -0 +3[/tex]

[tex]f(-1) = 3[/tex]

[tex]x = \infty[/tex]

[tex]f(\infty) = -\sqrt{\infty +1}+3[/tex]

[tex]f(\infty) = -\sqrt{\infty}+3[/tex]

[tex]f(\infty) = -\infty+3[/tex]

[tex]f(\infty) = -\infty[/tex]

So, the range is: [tex](-\infty, 3][/tex]

To get the interval where the function increases or not, we simply plot the graph of f(x).

See attachment for graph.

From the attachment, it will be observed that the graph of f(x) continuously decreases from x = -1, and it never increased.

This implies that, the graph decreases over the interval [tex](-1,-\infty)[/tex]

To find an area multiply all given side lengths and make sure to know what shape you are finding the area too because different shapes have different formula's. Parallelograms such as square rectangle or any parallel pair will be just L x W x H or L x W depends if its 2d or 3d

Answer:7(3+5)= 21+35

Step-by-step explanation:

Answer: y = 80*

all circles have 360* so we can subtract what we have to get what we want

360 - 110 - 90 - 80 = 80*

Step-by-step explanation:

Answer:

x= 128*

Step-by-step explanation:

180*-52*=128*

Answer:

x = 128

Step-by-step explanation:

well we know that for a polygon, the interior angles always add up to 360.

One angle is 52, and since the other two have squares it means that they are a perfect 90 degree angle. add those up to get 232, and then subtract 232 from 180 to get 128

Answer:

h=1ft

Step-by-step explanation:

The volume of a cone is:

v=πr^h/3

plug in the values (I am assuming not 1/18π but 1/18×π):

1/18π=  π1/3^2h/3

Get rid of the radius:

1/3^2=1/9

Continue:

π/18= πh/3*1/9= πh/18

Remove the denominators:

π=πh

Divide both sides by π :

h=1

Answer:

72 old houses

Step-by-step explanation:

Answer:

x = 25

Step-by-step explanation:

2x + 70 = 120      {Subtract 70 from both sides}

        2x = 120 -70

        2x = 50      {divide both sides by 2}

          x = 50/2

x = 25

Answer:

14.9 dollars

Step-by-step explanation:

1. There are 30 students and if everyone pay the same, it will be 14.9 dollar. Because the total is 447 dolar and if everyone pay equally, then everyone have the same amount. So, 447 dollar divided to 30 student equal 14.9 per student.

2. The essential information is the total cost of money and the amount of student.

3. 30m = 447

/30      /30

m= 14.9 dollar

4. 14.9*30 = 447
