Step-by-step explanation:

volume = pi*r^2*h

Using the formula

V=πr2h

Solving for h

h=V/πr2

=100/π·2^2≈7.95775

Answer:

9/9/108/126

Step-by-step explanation:

1/2bh is how you find the area of a triangle ! :)
This means that for both triangles, the area is 2 times the height, 9, then multiplied by one half. The area is 9 for both the left and right triangle.

The area of the rectangle is the product of the two lengths: 9 and 12, which is 108.

This means that the area of the entire trapezoid is 126.   :D

Step-by-step explanation:

Answer:

8)  14

10) 1

12) 81

Step-by-step explanation:

For number eight, you have to multiply out by 2. For example,

9 x 2= 18

2 x 2= 4

7 x 2= 14

For number ten, you have to subtract by 9. For example,

51 - 42= 9

10 - ___= 9

the space would be 1 because 10-1 equals 9

For number 12, you have to multiply out by 9

5 x 9=45

10 x 9= 90

9 x9= 81

Answer:

Selling Price 250

Profit =5%

We are given to find the cost price of articles .

First we find the profit

► Profit = 250/100 × 5

► Profit = 2.5×5

► Profit = 12.5

► Cost Price = 250-12.5

► Cost Price = 237.5

So, the cost price of the article is 237.5

Selling price of the article.

Profit percentage %.

To do:

We have to find the cost price.

Solution:

Let the cost price of the article be .

Profitpercent = SP-CP/CP × 100

5 = 250-x/x x 100

5x = (250-x) 100

x = (250-20) 20

x = 250 (20) - 20x

x + 20x = 5000

21x = 5000

x = 5000/21

x = 238

Therefore; cost price of the article is Rs 238

Answer:

y=1/2x+2

Step-by-step explanation:

The equations come in the form of y=mx+c, where m is the gradient and c is the y-intercept. Looking at the graph we know that the y-intercept is (0,2), so that rules out options B and C.

To find the gradient is a little more tricky, but we can follow the formula:

[tex]\frac{rise}{run}[/tex], where rise is the vertical value and run is the horizontal value

So we sub in our values:

[tex]\frac{2}{4}[/tex]

And simplify:

[tex]\frac{1}{2}[/tex]

So now we sub in our new found values into y=mx+c:

y=1/2x+2

Answer: y = x/2 + 2 which is the 4th option from the top

Step-by-step explanation:

First find the slope which is (0-2)/(-4-0) = 2/4 = 1/2

So it's y = x/2 + c

Substituing (-4,0) into the equation we get

0 = -4/2 + c

0 = c-2

c = 2

So the equation is y = x/2 + 2 which is the 4th option from the top

Answer:

B. [tex](4}, {\frac{13}{4})[/tex]

Step-by-step explanation:

[] Let's draw a picture

-> See attached

[] Looking at the picture and seeing the words halfway being used, we can tell we will need to use the midpoint formula.

-> See attached

[] We will use the midpoint formula between Sarah's house (7, -2) and Mandy's house (3, 5) to find Cameron's house.

[tex](\frac{7+3}{2}, \frac{-2+5}{2} )[/tex]

[tex](\frac{10}{2}, \frac{3}{2} )[/tex]

[tex](5, \frac{3}{2} )[/tex]

[] Now we will use the midpoint formula between Cameron's house ([tex](5, \frac{3}{2} )[/tex]) and Mary's house (3, 5) to find Kayla's house.

[tex](\frac{5+3}{2}, \frac{\frac{3}{2} +5}{2} )[/tex]

[tex](\frac{8}{2}, \frac{\frac{13}{2}}{2} )[/tex]

[tex](4}, {\frac{13}{2}*\frac{1}{2} )[/tex]

[tex](4}, {\frac{13}{4})[/tex]

-> This leaves us with option B. [tex](4}, {\frac{13}{4})[/tex]

Answer: -1,-1 + -2,-1

Step-by-step explanation:

You first take the verticle line and then the horizontal line and then you add point be by point A so basically its supposed to be -1+(-1)+(-1)+(-2) if I'm right.

Answer:

144 square feet

Step-by-step explanation:

First. the base is 6 by 6, meaning the surface area of it is 36 square feet. Then, we do a single triangle, whose area is (6*9)/2, or 27. 27*4 is 108, so the answer will be 108+36=144.

Answer is: 144 square feet

Have a great day! :)

Answer:

4^3 x 5^2

Step-by-step explanation:

Answer:

The number is 1.2 and the algebraic equation is 10x=12

Step-by-step explanation:

Since the product of a number and ten is 12, we can express it as the algebraic equation x*10=12, where x is any number.

x*10=12

10x=12

x=12/10

x=1.2

Therefore, The number is 1.2

Answer: z = [tex]\sqrt{10}[/tex]

Step-by-step explanation:

To find z, you must set up a proportion to solve.

To find the altitude of a special right triangle, the formula is:

[tex]\frac{a}{x} =\frac{x}{b}[/tex]

You can use 5 as a and 2 as b to complete the proportion:

[tex]\frac{5}{x} =\frac{x}{2}[/tex]

Next, to solve:

Step 1: Cross-multiply.

[tex]\frac{5}{z} =\frac{z}{2}[/tex]

(5)*(2) = z*z

10 = z²

Step 2: Take square root.

10 = z²

√10 = z
