Answer:

D

Step-by-step explanation:

The volume (V) of a cone is calculated as

V = [tex]\frac{1}{3}[/tex] πr²h ( r is the radius and h the height )

Here V = 226 and r = 12 ÷ 2 = 6 , then

[tex]\frac{1}{3}[/tex]π × 6²h = 226 ( multiply both sides by 3 to clear the fraction )

3.14 × 36h = 678

113.04h = 678 ( divide both sides by 113.04 )

h = [tex]\frac{678}{113.04}[/tex] ≈ 6 m ( to the nearest metre )

Solution

9 − − 8

Answer:

The answer is 9x - y - 8z.

Step-by-step explanation:

1) Expand by distributing terms.

[tex] - (8x + 6y) + 17x + 5y - 8z[/tex]

2) Remove parentheses.

[tex] - 8x + 6y + 17x + 5y - 8z[/tex]

3) Collect like terms.

[tex]( - 8x + 17x) + ( - 6y + 5y) - 8z[/tex]

4) Simplify.

[tex]9x - y - 8z[/tex]

Therefor, the answer is 9x - y - 8z.

Answer:

A) 10 units

Step-by-step explanation:

distance formula:

d=the square root of (x2-x1)^2 + (y2-y1)^2

(-5,4)

(3,-2)

d=the square root of (3-[-5])^2 + (-2-4)^2

d=the square root of 64+36

d=the square root of 100

d=10

Answer

128.86

Step-by-step explanation:

The box is 11x12 so 132.

The circles area is 3.14, or

A = πr^2 = π·1^2 ≈ 3.14159

So 132-3.14 is 128.86

Answer:

500 milliliters

Step-by-step explanation:

Dylan has 0.5 liters of water. He needs to find out how many milliliters of water he has so he can complete his science experiment. How many milliliters (mL) of water does Dylan have

1 liter of water = 1000 milliliters of water

0.5 liters of water = x

Cross Multiply

x = 0.5 × 1000 milliliters of water

x = 500 milliliters of water

Therefore, Dylan has 500 milliliters of water

The given center and point on the circle of (2, 3), and (5, 3), respectively

gives the equation of the circle as; [tex]\underline{(x - 2)^2 + (y - 3)^2 = 3^2}[/tex].

The general form of the equation of the circle is presented as follows;

(x - h)² + (y - k)² = r²

Where;

(h, k) = The center of the circle

r = The radius of the circle

Which gives;

(h, k) = (2, 3)

h = 2

k = 3

r = √((5 - 2)² + (3 - 3)²) = 3

The equation of the circle is therefore;

Answer:

See explanations below

Step-by-step explanation:

Let the amount of nickel be x

Let the amount of pennies be y

Let the amount of quarters be z

If the the total value of the coins is 3.88, then;

x+y+z = 3.88 .... 1

If Anita has 4 more nickels than pennies, then;

x = y + 4 ... 2

If she has 2 more than 4 times the number of quarters than pennies, then;

y = 2 + 4z

4z = y-2

z = (y-2)/4 ...3

Substitute 2 and 3 into 1

y+4+y+(y-2)/4 = 3.88

4y+16+4y + y-2 = 15.52

9y + 14 = 15.52

9y = 15.52 - 14

9y = 1.52

y = 1.52/9

y = 0.17

Since x = y + 4

x = 0.17+4

x  = 4.17

z = y-2/4

z = 0.17-2/4

z = -1.83/4

z = - 0.46

Answer:

x = 25

Step-by-step explanation:

The triangle is isosceles, therefore, the base angles are the same

62 + 2x + 9 + 2x + 9 = 180

62 + 4x + 18 = 180

4x = 180 - 62 - 18

4x = 100

x = 100/4

x = 25

Answer:

[tex]O = 14^\circ[/tex]

Step-by-step explanation:

Given

[tex]\angle Q = 90[/tex]

[tex]OP = 96[/tex]

[tex]PQ = 23[/tex]

Required

Find [tex]\angle O[/tex] to the nearest degree

To calculate O, we make use of:

[tex]sin(O) = \frac{PQ}{PO}[/tex] --- See attachment for triangle

[tex]sin(O) = \frac{23}{96}[/tex]

[tex]sin(O) = 0.2396[/tex]

Take arcsin of both sides

[tex]O = sin^{-1}(0.2396)[/tex]

[tex]O = 14^\circ[/tex] -- approximated
