Answer:

[tex]2713cm^3[/tex]

Step-by-step explanation:

From the given figure, the radius of the cylinder is=8cm, height of cylinder is =18cm  and the radius of the sphere is= 6cm.

Thus, [tex]Volume of cylinder={\pi}r^2h[/tex]

[tex]V=3.14(8)^{2}(18)[/tex]

[tex]V=3.14(64)(18)[/tex]

[tex]V=3617.28cm^3[/tex]

And [tex]volume of sphere=\frac{4}{3}{\pi}r^3[/tex]

[tex]V=\frac{4}{3}(3.14)(6)^3[/tex]

[tex]V=\frac{4}{3}(3.14)(216)[/tex]

[tex]V=904.31cm^3[/tex]

Thus, the volume of the shaded part of the figure=Volume of cylinder-volume of sphere

⇒volume of the shaded part of the figure=[tex]3617.28-904.31[/tex]

=[tex]2712.97[/tex]

≈[tex]2713cm^3[/tex]

Thus,volume of the shaded part of the figure=[tex]2713cm^3[/tex]

Step-by-step explanation:

To calculate the number of trees planted, divide the total length of the trail by 1/4 mile, or multiply by 4. This will give the number of trees in simplest form once the trail length is known.

To find the number of trees Edwina, Lexi, and Luis will plant along the trail, we need to divide the total length of the trail (in miles) by the distance between each tree (1/4 mile). Say the length of the trail is 'L' miles, the division expression will be L / (1/4). To evaluate this expression, remember that dividing by a fraction is the same as multiplying by its reciprocal. So the expression becomes L x 4, which gives the total number of trees planted along the trail. Without the specific length of the trail, we cannot calculate an exact number of trees. However, this formula helps us find the answer in simplest form once 'L' is known.

Final answer:

The probability of grabbing a yellow ball from a box with 2 green and 2 yellow balls is 0.5, calculated by dividing the number of yellow balls by the total number of balls.

Explanation:

In probability, the chance of an event happening is expressed as a fraction of the number of successful outcomes over the number of total possible outcomes. Since there are 2 yellow balls and 4 balls in total, the probability (P) of drawing a yellow ball is calculated as follows:

Number of successful outcomes (yellow balls) = 2

Total number of possible outcomes (total balls) = 4

P(yellow ball) = Number of yellow balls / Total number of balls = 2/4 = 0.5

Therefore, the probability of grabbing a yellow ball is 0.5 when expressed as a decimal.

Answer:

volume of water cup could hold is, 14.13 square inches.

Step-by-step explanation:

Volume of a cone(V) is given by:

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

where,

r is the radius of the cone

h is the height of the cone

As per the statement:

A  water cup is in the shape of the cone. The diameter of the cup is 3 inches and the height is 6 inches.

⇒height(h) = 6 inches and diameter(d) = 3 inches

We know that:

diameter(d) =2 (radius)

[tex]3 = 2r[/tex]

Divide both sides by 2 we get;

[tex]r = 1.5[/tex]

substitute these in [1] we have;

Use [tex]\pi = 3.14[/tex]

[tex]V = \frac{1}{3} \cdot 3.14 \cdot 1.5^2\cdot 6[/tex]

⇒[tex]V = \frac{1}{3} \cdot 3.14 \cdot 13.5[/tex]

Simplify:

[tex]V = 14.13 in^3[/tex]

Therefore, the volume of water the cup could hold is, 14.13 square inches.

Final answer:

The volume of water a cone-shaped cup can hold, with a diameter of 3 inches and height of 6 inches, using the formula for the volume of a cone, is 14.13 cubic inches.

Explanation:

The question asks us to calculate the volume of water a cone-shaped cup can hold given its dimensions. The diameter of the cup is 3 inches, and its height is 6 inches. To find the volume of a cone, we use the formula V = 1/3 πr²h, where V is the volume, r is the radius, h is the height, and π (pi) is approximately 3.14.

First, we find the radius of the cup. The diameter is 3 inches, so the radius (half the diameter) is 1.5 inches. Substituting the radius and the height into the formula, we get:

V =1/3 × 3.14 × (1.5²) × 6 = 1/3 × 3.14 × 2.25 × 6 = 1/3 × 3.14 × 13.5 = 14.13 cubic inches

Therefore, the volume of water the cup could hold is 14.13 cubic inches.

Ben builds ladders of different heights and put the number of rungs depending upon height of any particular ladder. He uses an equation for this construction that is given by :-

r = h ÷ 0.8

where h is the height of the ladder and r is the number of rungs in that ladder.

As we increase the height of the ladder, we need more rungs. If we decrease height, we would need lesser rungs.

Thereby, the number of rungs depend on the height of the ladder. It means value of r depends on value of h.

So r is dependent variable, and h is the independent variable.

Hence, option A is correct i.e. the height of the ladder.

For this case the total change is given by the following relationship:

Total change = Amount of money - Total costs.

Amount of money = $ 32

The total costs are given by the sum of each purchase.

We have then:

Total costs = 4 + (3 * 2) + 5 + 15

Total costs = 4 + 6 + 5 + 15

Total costs = $ 30

Substituting values we have:

Total change = 32 - 30

Total change = 2 $

Answer:

Answer:

The correct option is C.

Step-by-step explanation:

∵ The given graph is of increasing nature.

∴The base of the exponential will be greater than 1.

∴ option A is incorrect.

Also, at x=0 the value of y=3, but in option B at x=0 ⇒y= 3^0 =1

∴ option B is also incorrect.

At x=0, y=3 for option 3 which satisfies the graph.

∴ the option C is correct.

option D is incorrect because the base of an exponential can never be negative.

There is no hole in the graph of the function f(x) = x^2 - 9x - 3.

To find the coordinates of the hole in the graph of the function f(x) = x^2 - 9x - 3, we need to determine the x-value at which the function is undefined. This occurs when the denominator of the function is equal to zero. In this case, the function has no denominator, so there is no hole in the graph.

Let price of adult ticket is $x

And price of child ticket is $y

So we can make two equations using the given data

[tex] 3x+4y = 122 [/tex]

[tex] 2x+3y = 87 [/tex]

Now we can use eliminator method to solve the two equations

Multiply first equation by 2 and second equation by -3

[tex] 2(3x+4y = 122) [/tex]

[tex] -3(2x+3y = 87) [/tex]

[tex] 6x+8y = 244 [/tex]

[tex] -6x-9y =-261 [/tex]

now add both the equations so we get

[tex] 6x-6x+8y-9y=244-261 [/tex]

combine the like terms

[tex] -y=-17 [/tex]

Divide both sides by -1

[tex] y=17 [/tex]

Plug y=17 in any one of the equations to solve for x

[tex] 3x+4(17) = 122 [/tex]

[tex] 3x+68 = 122 [/tex]

Subtract 68 from both sides

[tex] 3x = 54 [/tex]

Divide both sides by 3

[tex] x=18 [/tex]

So x=18 and y=17

So

Price of adult ticket= $18

Price of child ticket = $17

Final answer:

When a number cube is rolled 63 times, it is predicted to land on a factor of 6, specifically 1, 2, 3, or 6, a total of 42 times. This prediction is based on the probability of 2/3 for each roll to result in a factor of 6.

Explanation:

A student asked: A number cube is rolled 63 times. Predict how many times the cube will land on a number that is a factor of 6.

To answer this, we first identify the factors of 6 on a six-sided number cube, which are 1, 2, 3, and 6. Because each side of a perfectly weighted cube has an equal chance of landing face up, the probability of landing on a factor of 6 each time the cube is rolled is determined by the number of sides with factors of 6 out of the total number of sides. In this case, 4 out of the 6 sides are factors of 6 (1, 2, 3, and 6).

The probability of landing on a factor of 6 for each roll is 4/6, which simplifies to 2/3. To predict how many times the number cube will land on a factor of 6 in 63 rolls, we multiply the total number of rolls by the probability of landing on a factor of 6:

Predicted occurrences = Total rolls × Probability = 63 × (2/3) = 42

Therefore, we predict that the number cube will land on a factor of 6 a total of 42 times out of 63 rolls.

Isabella needs a minimum of 9216 tiles to cover her 2ft by 2ft tabletop. This is calculated by converting all measurements to inches, finding the area of both the tabletop and a single tile, and dividing the total area of the tabletop by the area of a single tile.

To answer Isabella's question let's first convert everything into the same units to make it easier. The tabletop in inches would be 2ft * 12in/ft = 24in by 24in. The area of the tabletop is then 24in * 24in = 576in^2. Each tile is 1/4in by 1/4in in size, so the area of a single tile is 1/4in * 1/4in = 0.0625in^2. To find the minimum number of tiles needed to cover the tabletop, divide the total area of the tabletop by the area of a single tile: 576in^2 / 0.0625in^2 = 9216 tiles. Therefore, Isabella needs a minimum of 9216 tiles to cover the square tabletop.
