In this exercise we have to use the formula for volume of the cube and we find that:

Volume of cube is 1000m³

The formula is V = c * l * a, where:

Given that the length of side of cube = 10m, and knowing the formula the volume of cube is:

[tex]Volume of cube = (side)^3\\Volume of cube= (10)^3\\Volume of cube = 1000 m^3[/tex]

She needs to buy 6 bags of soil. the correct option is B

Given

Caisha has a circular garden with a radius of 4 ft.

She needs to put a layer of soil on top. e

Each bag of soil covers 9.42 square feet.

The radius of the circular garden is equal to the pie times of the square of the radius.

The radius of the circular garden is;

[tex]\rm Area = \pi r^2\\\\Area = 3.14 \times (4)^2\\\\ Area = 3.14\times 16\\\\Area =50.24[/tex]

Therefore,

The number of bags of soil will she need to buy is;

[tex]\rm = \dfrac{Area }{Soil \ covers}\\\\= \dfrac{50.24}{9.42}\\\\= 5.33\\\\= 6 \ bags \ apporx[/tex]

Hence, she needs to buy 6 bags of soil.

Explanation:

I took the test and got this question correct!

A= 20%

B= 33%

What is Relative Frequency?

Relative frequency is simply the number of outcomes in a particular subgroup (f) divided by the total number of outcomes in an experiment (n).

Thus, Relative frequency= f/n

In the above question, we need to find the relative frequencies of 2 subgroups- lifeguards and retail.

For lifeguards, f=3 and n=15

∴ Relative Frequency (A) = [tex]\frac{3}{15}[/tex]

Since we've to express it in percentage form,

A= [tex]\frac{3}{15}[/tex] * 100

  = 20%

Similarly for retail-

B= [tex]\frac{5}{15}[/tex] * 100

 = 33%

Thus, A= 20% and B= 33%

Answer: 9

Step-by-step explanation: Given The family size sunscreen bottle contains 12 fluid ounces of sunscreen. The standard bottle holds only 75% as much. The normal sunscreen container contains how many fewer fluid ounces?

A 12-ounce family-size bottle is available. However, the regular bottle contains 75% less.

So, 75/100 x 12 = 9 ounces.

As a result, a standard bottle may store 9 ounces of liquid.

Hope this helps!

Answer:

Step-by-step explanation:

So in our case, let assume 'x' as a common factor.

Thus,

4x + 5x + 7x = 5600;

16x = 5600;

x = 5600/16 = 350.

So,

4x= 350*4 =1400;

5x= 350*5 = 1750; &

7x= 350*7 = 2450.

Your answer is, 5600 = 1400+1750+2450 which is in ratio of 4:5:7.

Answer:

y = 8x

Step-by-step explanation:

See attached image.

Step-by-step explanation:

the standard form for a quadratic function is

y = ax² + bx + c

our parabola had the equation

y = a(x - 2)² + q

let's do the "math" :

y = a(x² - 4x + 4) + q = ax² - 4ax + 4a + q

so, we know (when comparing with the standard form)

b = -4a

c = 4a + q

for the vertex we need to find the axis of symmetry first by using the standard formula

x = -b/2a

which is in our case

x = -(-4a)/2a = 4a/2a = 2

to get y for this x we need to find a and q first.

we are using the given points for that :

5 = a(-2)² - 4a×(-2) + 4a + q

-1 = a(4)² - 4a×4 + 4a + q

the first equation then forms into

5 = 4a + 8a + 4a + q = 16a + q

the second equation forms into

-1 = 16a - 16a + 4a + q = 4a + q

let's subtract the second from the first equation

5 = 16a + q

- -1 = 4a + q

--------------------

6 = 12a + 0

12a = 6

a = 1/2

-1 = 4a + q = 4×1/2 + q = 2 + q

q = -3

so, the original equation for our parabola is

y = 1/2 × (x - 2)² - 3

so y for the vertex (remember, x = 2) is

y = 1/2 × (2 - 2)² - 3 = 1/2 × 0 - 3 = -3

so the vertex is (2, -3)

Answer:

Mr. Crow dimension of the lawn = 85 × 40

Area of the lawn = 3250 square feet

Step-by-step explanation:

Let x represents the width of the rectangle,

Then According to the question,

The length of the rectangle = 2 x + 5

Also it is given that the perimeter of the rectangle = 250 feet.

But we know that the perimeter of the rectangle = 2 × ( length + width)

Thus, the perimeter of the rectangle = 2( 2x+5+x) = 2(3x+5) = 6x+10

If x = 30,  the perimeter of the rectangle = 6 × 30 + 10 = 190 < 250

Thus, x ≠ 10.

If x = 50,  the perimeter of the rectangle = 6 × 50 + 10 = 310 > 250

Thus, x ≠ 50

If x  = 40, the  the perimeter of the rectangle = 6 × 40 + 10 = 250 = 250

Thus, x = 40

Therefore, the width of the rectangle, x  = 40 feet.

And, the length of the rectangle, 2 x + 5 = 2 × 40 + 5 = 85 feet.

1) The dimension of the rectangle = 85 × 40

2)The area of the rectangle = length × width = 85 × 40  = 3250 square feet.Let x represents the width of the rectangle,

Then According to the question,

The length of the rectangle = 2 x + 5

Also it is given that the perimeter of the rectangle = 250 feet.

But we know that the perimeter of the rectangle = 2 × ( length + width)

Thus, the perimeter of the rectangle = 2( 2x+5+x) = 2(3x+5) = 6x+10

If x = 30,  the perimeter of the rectangle = 6 × 30 + 10 = 190 < 250

Thus, x ≠ 10.

If x = 50,  the perimeter of the rectangle = 6 × 50 + 10 = 310 > 250

Thus, x ≠ 50

If x  = 40, the  the perimeter of the rectangle = 6 × 40 + 10 = 250 = 250

Thus, x = 40

Therefore, the width of the rectangle, x  = 40 feet.

And, the length of the rectangle, 2 x + 5 = 2 × 40 + 5 = 85 feet.

1) The dimension of the rectangle = 85 × 40

2)The area of the rectangle = length × width = 85 × 40  = 3250 square feet.

Answer:

88

Step-by-step explanation:

If the top layer has two​ logs, there are a total of 88 logs in the pile

Number of logs in the bottom layer = 22

Number of logs in the top layer = 2

Number of logs in each subsequent layer = 22 - 2 = 20

Number of layers in the pile = 22 - 2 + 1 = 21

Total number of logs in the pile = 22 + 20 + 18 + ... + 2

This is an arithmetic series with first term 22, last term 2, and common difference -4.

The sum of an arithmetic series is given by the following formula:

sum = (first term + last term)/2 * number of terms

sum = (22 + 2)/2 * 21 = 88

Therefore, there are a total of 88 logs in the pile.\

He bought 4 DVDs for $9.95 each, so $9.95*4=  $39.8 is his total cost.

Step-by-step explanation:

The equation that can be used to find the measure of angle LKJ  is

x = Sin⁻¹ (8.9/10.9).

Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle.

As we know that

sine of an angle = perpendicular/hypotenuse

Sine of ∠LKJ = 8.9/10.9

∠LKJ  = Sin⁻¹ (8.9/10.9)

x = Sin⁻¹ (8.9/10.9)

Therefore, the equation that can be used to find the measure of angle LKJ is x = Sin⁻¹ (8.9/10.9).

[tex] \frac{22.50}{4.5} = 5[/tex]

Answer:

A (2.5, 4 )

Step-by-step explanation:

the coordinates of A are the intersection of the 2 lines AB and AC , that is

2x + 3y = 17 → (1)

4x - y = 6 → (2)

multiplying (2) by 3 and adding to (1) will eliminate y

12x - 3y = 18 → (3)

add (1) and (3) term by term to eliminate y

14x + 0 = 35

14x = 35 ( divide both sides by 14 )

x = [tex]\frac{35}{14}[/tex] = 2.5

substitute x = 2.5 into either of the 2 equations and solve for y

substituting into (1)

2(2.5) + 3y = 17

5 + 3y = 17 ( subtract 5 from both sides )

3y = 12 ( divide both sides by 3 )

y = 4

solution is (2.5, 4 )

The length of the top surface is given by h(x) = 11x + 1.

Area is the amount of space occupied by a two dimensional object or figure. The area (A) of a rectangle is given by:

A = length * width

Let h(x) represent the width, hence:

66x² + 17x + 1 = (6x + 1)(11x + 1)

Since the width is g(x) = 6x + 1, hence the length = 11x + 1

The length of the top surface is given by h(x) = 11x + 1.
