Answer:

Answer is 19.2

Step-by-step explanation:

60x60= 3600 63x63= 3969

3969

- 3600 = 369 square root of the 369= is 19.2

The approximate height of the ramp is 19.2

Given: Tamika builds a wooden skateboard ramp. The ramp measures 63 centimeters, and the length of its horizontal base is 60 centimeters, as shown.

A right triangle with side lengths 60 centimeters, h, and hypotenuse 63 centimeters.

How to determine in centimeters, what is the approximate height of the ramp?

The area will be  60x60= 3600

=> 63x63= 3969.

Thus height is  3969- 3600 = 369 and the square root of the 369

=19.2

Answer:

The volume of the cone is 10 cubic units

Step-by-step explanation:

Given

Solid Shapes: Cone and Cylinder

Volume of Cylinder = 30 cubic units

Required

Volume of Cone

From the question; we have that the cylinder and the cone has the same height (h) and the same base;

Since they have the same base, then this means they have the same radius.

The Volume (V) of a cylinder is calculated as follows

[tex]V = \pi r^2h[/tex]

Substitute 30 for V

[tex]30 = \pi r^2h[/tex]

The Volume (Vc) of a cylinder is calculated as follows

[tex]V_c = \frac{1}{3} \pi r^2h[/tex]

From the volume of a cone, we have that [tex]\pi r^2h = 30[/tex]; This means that we can substitute 30 for [tex]\pi r^2h[/tex]

[tex]V_c = \frac{1}{3} \pi r^2h[/tex] becomes

[tex]V_c = \frac{1}{3} * 30[/tex]

[tex]V_c = 10[/tex]

Hence, the volume of the cone is 10 cubic units

Answer:

A

Step-by-step explanation:

Answer:

Step-by-step explanation:

We know Adam's high score was originally 250, but increased to 290. This would most likely affect the mean since the average mean before Adam received a high score of 290, would have been around 180-220.

We can prove this by hypothetically plugging in 220 for the other three players and 250 for Adam's orginal high score. To find the mean add up the total scores and divided them by four (number of people).

mean (maximum total score) = [tex]\frac{220 + 220 + 220 + 250}{4}[/tex]= 227.5

Then we can plug in Adam's high score of 290 that he late receives.

affected mean (maximum total score) = [tex]\frac{220+220+220+290}{4}[/tex] = 237.5

As you can see, the mean of the maximum total scores is increased by 10.

Now for the median.

The order of the numbers from least to greatest is:

Original- 220, 220, 220, 250 - median = 220

After- 220, 220, 220, 290 = 220

So, the median stayed as 220 and did not change.

Answer:

  30 square units

Step-by-step explanation:

The area of the given right triangle can be found a couple of ways:

The missing side length can be found using the Pythagorean theorem relation between the sides:

  c² = a² +b²

  13² = a² +5²

  a² = 169 -25 = 144

  a = √144 = 12

Then the area is ...

  A = 1/2ab = 1/2(12)(5) = 30 . . . square units

__

The angle at lower right can be found from the trig relation ...

  Cos = Adjacent/Hypotenuse

  cos(A) = 5/13

  A = arccos(5/13) ≈ 67.38°

The area can be found from these side lengths and the angle:

  A = 1/2bc·sin(A)

  A = 1/2(5)(13)sin(67.38°) = 30 . . . square units

_____

Additional comment

The sine of the angle can be computed from the cosine using the identity ...

  sin(x) = √(1 -cos²(x))

In this case, the sine of the angle would be found to be 12/13, so the area would be computed as ...

  A = 1/2(5)(13)(12/13) = 1/2(12)(5) . . . . same as using the Pythagorean theorem

Answer:

B

Step-by-step explanation:

you round 33 to 30 and 87 to 90

Answer:

Well I think it's B.. Sorry for the late answer.

Step-by-step explanation:

First, I need to decide what equation this is like.

I believe this is y=mx.

We know that x is typically the input, and m is the constant function.

Y is the output.

So the original function may have been y=200x.

The only difference is now we've been given something to apply to the equation, in place of x.

2. Imagine a cloning machine. Whatever you put in, you get a copy of, and the original thing you put in. Its function would be y=2x. Let's pretend we decided to put three things in; 3 would go where x is.

Y would be the result of 3 copies and their originals, or 2(3).

(6=2(3))

Now, when someone else decides to use the cloning machine, they may put any number in, but the only properties that will change are y and x, not m.

The function will remain y = 2x. Any number could go in place of x, and multiplying x by 2 will give you the y. As long as you have a different value for x, the y will never be the same.

3. So now we have an understanding of what it means, we see that we have been given an x value to insert; an input.

A more practical example could be someting with money. This won't be entirely realistic, because we are dealing with a fraction of a number and another large number.

4. I decided to go with flour. I wanted the 200 to represent pennies, or cents. Before I landed on this, I looked up the cost of flour per pound. I found that the average is .43 dollars, which isn't terribly close to two dollars. But maybe the flour is high quality, so we can stick with that.

5. Seeing that this equation, y=200x, means we are charging 200 cents, or two dollars, we can write a problem from here.

Sylvia is in charge of selling home-harvested flour from an organic farm. She charges two dollars per pound of flower. Today, her next-door neighbors hope to buy a ninth of pound of flour, and they insist on paying with pennies. How many pennies do they need to pay for their order?

Answer:

1/2

Step-by-step explanation:

Answer:

y=3, x=5

Step-by-step explanation:

18=6y, so divide both sides by 6 to get 3=y.

45=9x, so divide both sides by 9 to get x=5.

Answer:

x=5 y =3

Step-by-step explanation:

Opposite interrior angles have the same Number of degrees. So 9x=45. X has to be 5. y = 3 because 3 times 6 is 18. Which is the same number as the opposite vertical side.

Answer:

8 outcomes

Step-by-step explanation:

A coin has two possible outcomes: heads or tails.

The spinner has four possible outcomes: 1, 2, 3 or 4.

If we combine then, the number of outcomes will be the product of their number of outcomes:

2 * 4 = 8

So we will have a total of 8 outcomes:

heads, 1 / heads, 2 / heads, 3 / heads, 4 /

tails, 1 / tails, 2 / tails, 3 / tails, 4

Answer:

Step-by-step explanation:

factor out 100

100[7 + (4 * 11) + (8 * 110)]

100[7 + 44 + 880]

100 (931)

= 93100

standard form is 9.31 * 10^4

The standard form for the number (7×100)+(4×1100)+(8×11,000) is,  9.31×10⁴

The standard form for a number is a method by which we write number in a format like  b×10ˣ. The value of b should be in between 0 to 10.

Given Number,

⇒ (7×100)+(4×1100)+(8×11,000)

   by taking 100 common from all the three terms,

⇒  100[ 7+ (4×11) + (8×110) ]

⇒  100[7+44+880]

⇒   100×931

⇒    9.31×10⁴

Hence, The number can be written as,  1.39×10⁴

The required percent increase is 12%

Tamanika got a raise in her hourly pay, from $15.50 to $17.36

percentage is defined as, composition of something out of whole inbounds of 100.

since = 17.36 - 15.50/15.50 x 100
= 1.86/15.50 x 100

Answer:

[tex]232 cm^{2}[/tex] (B.)

Step-by-step explanation:

Don't overwhelm yourself. Take a deep breath and look at the triangle that has the height of 14 cm.

Recall that the area of a triangle is A= 1/2bh

The base of the triangle is 8 cm, if you eyeball it with the square. The height is given as 14.

1/2 (14)(8)

= 56 cm^2 x 2

= 112 cm^2

Great! We found two of the triangles (there are two of these, look at the paper)

Now let's take a look at the second triangle with the height of 12 cm.

Eyeball the base, which is 6 cm from the square in the middle.

1/2 (6)(12)

= 36 x 2

= 72 cm^2 (there are two of these triangles)

The easy part comes. The area of a square is simply

A= bh

= (6)(8)

= 48 cm^2.

ADD 'EM UP

48 + 72 + 112

= 232 cm^2

Answer:

B) 232

Step-by-step explanation:

Do 14 x 8 to find the top and bottom triangle. 112. Then do 12 x 6 to find the left and right triangle. 72. The find the area of the rectangle 6 x 8 = 48. Add up all the answers. 112 + 72 + 48 = 232 is the answer.
