The formula for the volume of a cone is V = 1/3 πr^2 h. Which part of the formula represents the area of the base?

Answer:

[tex]\frac{x}{y} = \frac{8}{5}[/tex]

Step-by-step explanation:

Given

[tex]5x^2 - 13xy + 8y^2 = 0[/tex]

Required

Find x/y

[tex]5x^2 - 13xy + 8y^2 = 0[/tex]

Expand

[tex]5x^2 -5xy - 8xy + 8y^2 = 0[/tex]

Factorize:

[tex]5x(x - y) - 8y(x - y) = 0[/tex]

Factor out x - y

[tex](5x - 8y)(x - y) = 0[/tex]

Divide both sides by [tex](x-y)[/tex]

[tex]5x - 8y = 0[/tex]

Add 8y to both sides

[tex]5x = 8y[/tex]

Divide both sides by 5

[tex]x = \frac{8}{5}y[/tex]

Divide both sides by y

[tex]\frac{x}{y} = \frac{8}{5}[/tex]

Answer:

400+1200

1600inches^2

Answer:

Step-by-step explanation:

Only j,q,k beat 10 and there are four each of them so there are 12 cards that will beat the ten. 4 cards have already been drawn so there are 52-4=48 cards left in the deck, so the probability of beating the 10s is

12/48

1/4

Which is 25%

Answer:

[tex]a^{2}(24a^{2}+36a+12)[/tex]

Step-by-step explanation:

Area of rectangle= Length*Width

so [tex](6a^{2}+9a+3)*4a^{2}[/tex]   multiply each coefficient of a times 4a^2

[tex]24a^{4}+36a^{3}+12a^{2}[/tex]  then take a^2 common factor so it will be

[tex]a^{2}(24a^{2}+36a+12)[/tex]=area

Answer:

m<1 = 125°

Step-by-step explanation:

Given that line m is parallel to line n, therefore:

m<2 = m<6 (corresponding angles theorem)

m<2 = 55°

Therefore,

m<1 = 180° - m<2 (linear pair)

m<1 = 180° - 55°

m<1 = 125°

Answer:

274.05 (I assume they round it to A. 274.1)

Step-by-step explanation:

The figure seems to be comprised of 7 triangles, each of base 8.7 and height 9.

total area would be

7 * (8.7 * 9 / 2) = 7 * 39.15 = 274.05

Answer:

he's not correct.

-15 = m

Step-by-step explanation:

-16 = -1 + m

-16 + 1 = m

-15 = m

Why does -1 became +1 , It is because you are adding 1 on both side so that we can cancel out the -1 and it will rest the m.

like this;

+1 -16 = -1 + m +1

-16 + 1 = (0 or nothing) + m

-15 = m

Answer:

The answer is A.

Step-by-step explanation:

The school needs AT LEAST $5000 dollars. The only answers that say at least $5000 is A. and C. Then the school gave them 1000. So the answer would state that 60 students times the amount of money needed to be raised plus the additional money the school gave them is greater than 5000.

A. is saying that 60 students times X, which equals how much money each member has to raise. Plus 1000, which is how much the school gave them. Is greater than 5000 which is at least how much the need to raise.

Answer:

Step-by-step explanation:

sin^-1 (21/67) = 18.27 degrees

√(67)^2 - (21)^2 = 63.62

2x(x-1) = 2x - 2

Step-by-step explanation:

a thing my math teacher always taught that sticks is that the equals sign is essentially the words is the same as. Think of it this way the sentaxe would be 2x -2 is the same as 2x minus 2. we get this because initially with the parentheses we have to take the number outside which is 2 and multiply everything inside by it. 2 times x equals 2x and 2 times -1 is negative 2.

Answer:

How to solve your problem

Step-by-step explanation:

Common factor

−2+5

−1(2−5)

Solution

−1(2−5)

You have 2 points with the same x value of 2 and 2 points with the same y value of 4.

You now need 2 points with the same x value of 4 ( you are given 1) and 2 y values of 1 ( you are given 1.

The missing point would need to be (4,1)

The width would be x2-x1 = 4-2 = 2 units

The length would be y2-y1 = 4-1 = 3 units

Area = 3x 2 = 6 square units

Answer: 0.075

Step-by-step explanation: when you are working with percentages to decimals you want to move the decimal two places to the left. If you are working with decimals and you want to make it a percentage you would move the decimal two places to the right.

Answer:

7.5% = 0.075

Step-by-step explanation:

Whenever you're converting a percentage into a decimal, you multiply the percentage by 100, or move the decimal point two points to the left. So, 7.5% as a decimal is 0.075.

The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same ratetion:

Answer:

x=3.5

Step-by-step explanation:

12x=4(x+2)+20

multiply the parentheses by 4

12x = 4x+8 +20

add 20 to 8

12x = 4x +28

subtract 4x on both sides

8x = 28

divide both sides by 8

x=3.5

Answer:

9.[tex] \:\:x = 3. 5[/tex]

10. y = 8x + 12

Step-by-step explanation:

9.

12x = 4(x + 2) + 20

12x = 4x + 8 + 20

12x - 4x = 28

8x = 28

x = 28/8

x = 7/2

[tex] x = 3.5 [/tex]

10.

Slope (m) = 8

Line is crossing y-axis at (0, 12)

y-intercept (b) = 12

Equation of line in slope-intercept form is given as:

y = mx + b

Plugging the values of m and b in the above equation, we find:

y = 8x + 12

y=mx+b

y-y1=m(x-x1)

Ax+By= C

Answer:

I think the answer may be 140°

360 - 160 - 60 = 140

Answer:

12.5 sq. units

Step-by-step explanation:

Area of a Trapezoid Formula: (see the image attached)

7.5 + 2.5 = 10

10/2 = 5

5(2.5) = 12.5

So, the area of the trapezoid is 12.5 sq. units.

Answer:

With what?

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

a)

The area of the figure = sum of the area of the individual polygons

The area of the figure = x + 1 + y + 1 + x = 2x + y  + 2

The perimeter of the figure = sum of the length of the sides = 2(1 + (x + 1 + y + 1 + x)) = 2(2x + y + 3) = 4x + 2y + 6

b)

a)

The area of the figure = sum of the area of the individual polygons

The area of the figure = y² + xy + 1 + 1 + 1 = y² + xy + 3

The perimeter of the figure = sum of the length of the sides = (y + 1) + x + y + (y + 1) + y + 1 + 1 + 1 + x + 1 = 4y + 2x + 6
