Answer:

The chest is 2 feet deep.

Step-by-step explanation:

Given:

Aponi built a toy chest for her niece. It has a volume of 12 cubic feet, the chest is 3 feet long and 2 feet wide.

Now, to find the depth of it.

Length = 3 feet.

Width = 2 feet.

Volume = 12 cubic feet.

Now, to find the depth by using formula:

[tex]Volume= length\times width\times depth\\\\12=3\times 2\times depth\\\\12=6\times depth\\\\Dividing\ both\ sides\ by\ 6\ we\ get:\\\\2=depth\\\\Depth=2\ feet.[/tex]

Therefore, the chest is 2 feet deep.

The solutions to the inequality (k - 3)/4 > -2 are k = -1 and k = 0. This is determined by solving the inequality step by step and checking each given value.

To find the solutions, we need to solve the inequality step by step:

Now we find the values from the given options that satisfy k > -5:

Thus, the values that are solutions to the inequality are k = -1 and k = 0.

The complete question is

Which values are solutions to (k - 3)/4 > - 2' Select two options.

k = - 10

k = - 7

k = - 5

k = - 1

k = 0

Answer:

[tex]x = \frac{40}{-30\\}[/tex]

Step-by-step explanation:

Lets start by working with our numbers on the right side of the equation.

Begin by using distributive property, turning:

2x = 8(4x - 5) into 2x = 32x - 40

To make things easier, lets subtract 32x on both sides

-30x = 40

Finally, divide by -30 on both sides to get our answered, simplified if necessary:

[tex]x = \frac{40}{-30} = \frac{4}{-3} = -1.33[/tex]

The number of possible sets of four marbles from the bag is 126 sets, calculated using the combinations formula, C(9, 4) = 9! / [4! * (9-4)!].

To determine the number of possible sets of four marbles from a bag containing two red marbles, two green ones, one lavender one, two yellows, and two orange marbles, we can use the concept of combinations in mathematics. The formula for combinations is given by

C(n, k) = n! / [k! * (n-k)!]

where n represents the total number of items to choose from, k represents the number of items to choose, and ! indicates factorial which is the product of all positive integers up to the number.

First, we count the total number of marbles:

2 red 2 green 1 lavender 2 yellow 2 orange2 red

Thus, n=9 total marbles in the bag. We want to choose k=4 marbles out of these.

Applying the combination formula:

C(9, 4) = 9! / [4! * (9-4)!] = 126

Therefore, there are 126 possible sets of four marbles that can be chosen from the bag.

Answer:

3 in²

Step-by-step explanation:

Since you can derive that the 2 squares completely fill the grid, you can look at the extra pieces that don't fill it. Each extra piece seems to fit 1/4 of the square grid and since there are 4, it completes a whole square.

Altogether, 2 + 1 = 3 squares, estimated.

Answer:

56π = 175.929, so no.

Step-by-step explanation:

Surface area formula: 2B+Ph (where B is area of the base, P is perimeter of the base, and h is height.)

2(4π) + 4π(12)

8π +48π

56π = 175.9 ft^2

The are of the given heptagon is 243 u³.

In the given polygon,

Number of sides = 7

Hence this is a heptagon, which has,

Length of edge = 9 unit

Polygons are two-dimensional geometric figures with a fixed number of sides. A polygon's sides are made up of straight line segments that are joined end to end. As a result, the line segments of a polygon are referred to as sides or edges.

Since we know that,

Area of heptagon = (7 / 4) × edge² × cot(π/7)

Therefore,

Area of heptagon = (7 / 4) × 9² × cot(π/7)

                              = (7/4) x 81 x 2.07

                              ≈ 243 u³

Hence,

The area is approximately 243 u³

Step-by-step explanation:

(i) Area of the first cross section

base,b = 8 m, height,h = 10 m

Area of the triangle = [tex]\frac{1}{2}[/tex] bh

area =  [tex]\frac{1}{2}[/tex] (8) (10)

area = 40 m²

(ii) Area of the second cross section

Answer: 5/6

Step-by-step explanation:

Over 2 there are 4 numbers 3,4,5,6 but it can be odd so also 1 works there are 6 numbers in total and 5 numbers work so

5/6

Answer:

5/6

Step-by-step explanation:

I got 5/6 because every number matches the conditions set except for two. If Glenn rolls a 1, it works because it is an odd number. If Glenn rolls a 2 it doesn't work because it's not an odd number and its not greater than 2. If Glenn rolls a 3 it works because 3 is an odd number and is greater than two, and every number after three will also work, because they are all greater than two. This way, the only number that will not match the conditions is 2, so the answer is 5/6, or 83.(3)%

Answe4.516439288 x 10²² ways

Step-by-step explanation:

The number of ways the songs in the playlist can be played involves a permutation, since order is involved.

8 rock songs can be played out of 20 in:

20P8 ways = 20!/(20-8)!

= 20!/12! = 6.033983155 x 10^13 ways

Similarly, 6 rap songs can be played from 18 in:

18P6 ways = 18!/(18-6)!

= 18!/12! = 8.892185702 x 10^12 ways

Hence, the number of ways 8 rock and 6 rap songs can be played from the disc's library is a multiplication of both permutations, which yields:

4.516439288 x 10²² ways

Answer:

x = 1

Step-by-step explanation:

0.5x-0.3=0.2

1. Multiply both sides by 10.

0.5x*10-0.3*10=0.2*10

2. Refine.

5x-3=2

3. Add 3 to both sides.

5x-3+3=2+3

4. Simplify.

5x=5

5. Divide both sides by 5.

5x/5=5/5

6. Simplify.

x=1

Answer:

Step-by-step explanation:

0.5x  - 0.3 = 0.2

add 0.3 to both the sides

0.5x - 0.3 + 0.3 = 0.2 + 0.3

0.5x + 0 = 0.5

0.5x = 0.5

Final answer:

The product of the provided series of numbers is 0, because multiplying any number by zero will always result in zero.

Explanation:

The product of a series of numbers is the result of multiplying all the numbers together. In this case, you have provided a list of numbers: -3, 4, 2, -5, 3, -2, 1, 0. To find their product, we multiply them one by one.

Multiplying any number by zero results in zero, which is an important mathematical rule. Since one of the numbers in the list is 0, the product of these numbers is 0 regardless of all other numbers.

The x-intercepts of the function are (0,0) and (-2,0). Therefore, options A and C are correct.

To determine the x-intercepts of a function, we need to find the values of x when the function value, f(x), is equal to zero. Therefore, we need to plug in 0 for f(x) and solve for x.

From the given points, we can see that the function passes through the points (-2,0), (0,0), and (1,0), (2,0). Therefore, the x-coordinates of these points are the possible x-intercepts of the function.

Setting f(x) to zero for each of the points, we get:

At (-2,0): f(-2) = 0, so x = -2 is an x-intercept.

At (-1,-2): f(-1) = -2, so x = -1 is not an x-intercept.

At (0,0): f(0) = 0, so x = 0 is an x-intercept.

At (1,0): f(1) = 0, so x = 1 is an x-intercept.

At (2,0): f(2) = 0, so x = 2 is an x-intercept.

Therefore, the x-intercepts of the function are (0,0) and (-2,0).

Answer:

The value of x is 40.

Step-by-step explanation:

These are vertical angles meaning that these are both the same angle. We can express this into an equation. (3x - 6) = 114, usually with an equation like this we add the 6 from (3x - 6) and also add it to 114 because whatever you do to one side of the equation you have to do to the other. Because we added 6 to (3x - 6) the 6 from there is gone and since we added 6 to 114 it is now 120 so now the equation is 3x = 120. Now we divide each side me 3 to get the value of x. 3x divided by 3 is x. 120 divided by 3 is 40. So now our equation looks like this, x=40. So this is how the value of x is 40. Let me know if it's right!!
