Answer:

The radius of a circle with a dimeter of 1.8 inches is 0.9 inches.

Step-by-step explanation:

To find the radius of a circle from diameter, you divide the diameter by 2.

When we divide 1.8 by 2 we get 0.9.

Answer:

Possibly b

Step-by-step explanation:

IM pretty sure because the width is around the volume

sorry if im wrong but im pretty sure that it is B

By using the graph, all of the true statements that apply include the following:

B. The variables are dollars and hours.

C. Hours is the independent variable and dollars is the dependent variable.

F. The relationship is y = 3.50x.

In Mathematics and Geometry, a proportional relationship is a type of relationship that produces equivalent ratios and it can be modeled or represented by the following mathematical equation:

y = kx

Where:

Next, we would determine the constant of proportionality (k) by using the various data points from table D as follows:

Constant of proportionality, k = y/x

Constant of proportionality, k = 3.5/1 = 7/2 = 10.5/3

Constant of proportionality, k = 3.50

Therefore, the required linear function is given by;

y = kx

y = 3.50x

Answer: 94.54 m^2 (square meters)

Step-by-step explanation: The formula for the area of a trapezoid is A = 1/2(a+b)h; where a and b are the two top sides of the trapezoid that are parallel. Let us then solve.

Let us combine both sides two maintain the overall side for "b", which is 18 + 5.1 = 23.1

Let us now add both sides (a + b.) 23.1 + 9.5 is 32.6. We can now multiply by the height. 32.6 multiplied by 5.8 is 189.08

We can now divide (or multiply by 1/2), which is 189.08 * 1/2 or 189.08/2 and that equals 94.54.

Step 1

Find the area of the Rectangle in the middle

To find the area, you have to do [tex]Length*Width[/tex]

[tex]9.5*5.8=55.1[/tex]

The area of the Rectangle in the middle is 55.1m²

Step 2

Find the area of the triangle on the right

To find the area of 1 triangle, we have to use the formula show below:

[tex]A=\frac{1}{2}* Base *Height[/tex]

Base = the part on the bottom

Height = How high the triangle is

[tex]A=\frac{1}{2} *5.1*5.8\\=\frac{1}{2} *29.58\\=14.79[/tex]

The area of the triangle on the right is 14.79m²

Step 3

Find the area of the triangle on the left

Using the formula that we used in the last question about finding the area of the triangle, we can find our answer, here is the formula:

[tex]A=\frac{1}{2}* Base *Height[/tex]

Base = the part on the bottom

Height = How high the triangle is

BUT, before finding the area of this part of the triangle, we have to first find the dimensions, we know the height, but we don't know the base, so to find the base, we will subtract 18 by 9.5 to get our base

[tex]18-9.5=8.5[/tex]

So the base of the triangle on the LEFT is 8.5m

NOW, we can find the area of the triangle on the left

[tex]A =\frac{1}{2}* 8.5*5.8\\=\frac{1}{2} *49.3\\=24.65[/tex]

So the area of the triangle on the LEFT is 24.65m²

Step 4

Add up all the areas to get final answer!

The areas of the 3 shapes are...

55.1m²

14.79m²

24.65m²

Answer:

1005.3 [tex]ft^{3}[/tex]

Step-by-step explanation:

V=π r^2 h = π · 42· 20 ≈ 1005.30965 ---> 1005.3

Answer:

the answer to this question should be 1004.8 because first you need to use this formula to find the volume of a cylinder which is V=TTr^2h so remember the radius is half of the diameter.

So the half of 8 is 4 so 4 is the radius but remember that 4 is to the power of 2 in the exponent so the answer should be 16 because you multiplied 4 times 4 equals 16.

Then we need to multiplied 16 times 3.14 and 20 and when we do that we get an answer of 1,004.8 so 1004.8 feet^3 is the correct answer.

Step-by-step explanation: :DDDDD give brainliest to the first people that answer first than me if you want and have a great day.

Answer:

I believe the answer is about 95 percent.

Step-by-step explanation:

The reason for this answer is because as said 22 and a fifth would mean the tank is full. This means I set up a proportion. What I did was...

22 1/5 over 100 = 21 over x

Now: I do 21 multiply by 100 divided by 22 1/5 to get the answer

What I just wrote is the rule of proportions

Finally, after doing all of that, the answer I got was 94.59459459, but I rounded to the answer of 92 percent.

The answer is option C( 2009.6)

[tex] {in}^{3} [/tex]

Answer:

2009.6 in^3

Step-by-step explanation:

The formula for finding the volume of a cylinder is:

V=Bh

B= area of the base

h= height

Diameter= 16 radius= 16/2=8

V= (3.14*8^2)10

V= (3.14*64)10

V= 200.96(10)

V= 2009.6 in^3

Kavinsky

You scored 57 points on your math quiz. the correct answer would be an option (D).

The percentage is defined as a ratio expressed as a fraction of 100.

You scored a 95% on your math quiz.

You have to determine the evaluation of 95% of 60.

⇒ 95% of 60

95%  is expressed as 15/100 in fractional form

⇒ (15/100)(60)

95/100  is expressed as 0.95 in decimal form

⇒ (0.95)(60)

Apply the multiplication operation, and we get

⇒ 57

Therefore, 95% of 60 would be 57.

Answer:

The perimeter is 380 ft^2.

Step-by-step explanation:

To find the perimeter of a rectangle, you have to use the 2(a+b) formula as a method of solving. This formula can also be written as a+b+a+b or 2a+2b.

To solve it, you input a as 51 and 139 as b, though this doesn't really matter all too much. Using the previously stated formula, you should get 2(51+139). Solving what's in the parenthesis first (51+139), you should get 190.

Now, you should have the answer 2(190). Finishing off the equation and multiplying 2 by 190, your answer will be 380 ft^2.

Answer: See in the explanation

Step-by-step explanation:

The domain is all of the X values in a set.  

The range is all of the Y values in a set.

You can tell if a set of coordinate pairs is a function if each x value corresponds to 1 Y value. For example, lets say we have an x value of 3. This X value can only correspond to ONE y value. So if the x value 3 corresponded to , e.g, 4, or 7 as y values, it would not be a function because 1 x value has to have only 1 y value. 

a. {(0,9), (8, 1), (-1, 9), (9, 8), (1, -1)}

* This relation is a function, because there aren't many of the same x value numbers.

* The domain is {0, 8, -1, 9, 1}. Those are all of the X values

* The range is {9, 1, 9, 8, -1} (All of the Y values)

b. {(62, -3.1), (61, -3.1), (60, -3.1), (-3.1, -3.1)}

* This relation is a function, because even though all of the y values are the same , the x values are different.

* The domain is {62, 61, 60, -3.1}.

* The range is {-3.1, -3.1, -3.1, -3.1}

c. {(123,876), (-15, 2.6), (2.6, -15), (123, 1), (-87, -0.98)}

* This relation is a function, because all of the X values are different

* The domain is {123,876, -15, 2.6, 123, -87}

* The range is {0, 2.6, -15, 1, -0.98}

d. {(2.9, 0), (2.9, 1), (2.9, 2), (2.9, 3)}

* This relation is not a function. All of the x values are the same, and for this reason, they all have different y values.

* The domain is {2.9, 2.9, 2.9, 2.9}

* The range is {0, 1, 2, 3}

Answer:

8 outcomes

if you are spinning the spinner once.

Answer:

8.

Step-by-step explanation:

Any one of the 8 sections  can be the result of a spin.

During the first week of her training, she runs 200 meters.  On the second week, she plans to run 50% more.  

Now, how do you calculate this?

To increase 200 meters by 50%, multiply by 1.5

The second week she pans to run 450 meters.

Since there are only 3 weeks, do it again!

The thrid week, she plans to run 675 meters.

Since she runs the same ammount each day of the week, the calculation is simple.

7(200) + 7(450) + 7(675)

In these three weeks, she runs 9275 meters.

OR, she runs 10143.26 yards.

The amount of money seren had will be $132.

It is defined as the linear relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Given that:-

The solution will be done by making an equation:-

According to the first condition:-

S    +    V   =    $180

Now from the second condition:-

S   -   20   +   { ( v  +  20 ) / 4 ) }  =  180

Since   S   =   v  then:-

S   -    20   +    { ( S  +  20 ) / 4 ) } = 180

S  =   $132

Therefore the amount of money seren had will be $132.
