Answer:

Side = 3 cm

Step-by-step explanation:

Given:

[tex]\text{Volume of cube} = 27 \ \text{cm}^{3}[/tex]

The formula to calculate the volume is (Side)³.

Thus, we obtained the following equation:

[tex](\text{Side})^{3} = 27 \text{cm}^{3} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\text{Side}^{3} = \text{Volume of cube}][/tex]

Cube root both sides to obtain the side length of the cube:

[tex]\implies \sqrt[3]{\text{(Side)}^{3}} = \sqrt[3]{27 \ \text{cm}^{3} }[/tex]

Evaluate the side of the cube:

[tex]\implies \sqrt[3]{\text{(Side)}^{3}} = \sqrt[3]{27 \ \text{cm}^{3} }[/tex]

[tex]\implies \sqrt[3]{\text{(Side)}\text{(Side)(Side})} = \sqrt[3]{3 \times 3 \times 3 \times \text{(cm)(cm)(cm)}}[/tex]

[tex]\implies \text{Side = 3 cm}[/tex]

Answer:

3 cm

Step-by-step explanation:

Formula

Volume of a cube = [tex]a^3[/tex]  (where a is the side length)

Given that the volume of the cube is 27 cm³, to find the side length, substitute the given volume into the equation and solve for [tex]a[/tex]:

[tex]\implies 27\: \sf cm^3=a^3[/tex]

Cube root both sides:

[tex]\implies \sqrt[3]{27\: \sf cm^3} =\sqrt[3]{a^3}[/tex]

[tex]\implies \sqrt[3]{27}\sqrt[3]{\sf cm^3} =\sqrt[3]{a^3}[/tex]

[tex]\implies 3\: \sf cm=a[/tex]

[tex]\implies a=3\: \sf cm[/tex]

Therefore, the length of each side of the cube is 3 cm.

a = 12, b = 3*sqrt(17)

========================================================

Work Shown:

3/a = a/48

3*48 = a^2

a^2 = 144

a = sqrt(144)

a = 12

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

a^2 + 3^2 = b^2 ... pythagorean theorem

12^2 + 3^2 = b^2

144 + 9 = b^2

b^2 = 153

b = sqrt(153)

b = sqrt(9*17)

b = sqrt(9)*sqrt(17)

b = 3*sqrt(17)

Check the picture below.

[tex]sin(\theta )=\cfrac{\stackrel{opposite}{9}}{\underset{hypotenuse}{15}}~\hfill cos(\theta )=\cfrac{\stackrel{adjacent}{12}}{\underset{hypotenuse}{15}}~\hfill tan(\theta )=\cfrac{\stackrel{opposite}{9}}{\underset{adjacent}{12}} \\\\\\ cot(\theta )=\cfrac{\stackrel{adjacent}{12}}{\underset{opposite}{9}}~\hfill sec(\theta )=\cfrac{\stackrel{hypotenuse}{15}}{\underset{adjacent}{12}}~\hfill csc(\theta )=\cfrac{\stackrel{hypotenuse}{15}}{\underset{opposite}{9}}[/tex]

Reason:

Subtract any pair of adjacent terms

Each time we get the same value to confirm that we have an arithmetic sequence of common difference 18.

Answers:

Final velocity = 29 m/s

Distance traveled = 73.5 meters

========================================================

Work Shown:

The given data is

[tex]v_i = 20 \text{ m}/\text{s} = \text{initial velocity}\\\\a = 3 \text{ m}/\text{s}^2 = \text{acceleration}\\\\t = 3 \text{ s} = \text{time duration}\\\\[/tex]

This leads to

[tex]v_f = v_i + a*t\\\\v_f = 20 + 3*3\\\\v_f = 20 + 9\\\\v_f = 29\\\\[/tex]

The final velocity is 29 m/s.

----------

We can use that final velocity to find the distance traveled.

[tex]x = 0.5*(v_i+v_f)*t\\\\x = 0.5*(20+29)*3\\\\x = 0.5*(49)*3\\\\x = 24.5*3\\\\x = 73.5\\\\[/tex]

The distance traveled is 73.5 meters.

----------

An alternative way to calculate the distance is to do this

[tex]x = \frac{(v_f)^2 - (v_i)^2}{2a}\\\\x = \frac{(29)^2 - (20)^2}{2*3}\\\\x = \frac{841 - 400}{6}\\\\x = \frac{441}{6}\\\\x = 73.5\\\\[/tex]

Or you could do this

[tex]x = v_i*t + 0.5*a*t^2\\\\x = 20*3 + 0.5*3*3^2\\\\x = 20*3 + 0.5*3*9\\\\x = 60 + 13.5\\\\x = 73.5\\\\[/tex]

Answer: 6217728

Step-by-step explanation: The formula for a Rectangular Prism is (Base/Length)(Width)(Height). (12)(512)(1012).

Using proportions, that is, finding 25% of 12 km, it is found that she has already biked 3 km on Tuesday.

A proportion is a fraction of a total amount.

In this problem, she has already biked 25% out of her goal of 12 km, hence the distance that she has biked is given by:

d = 0.25 x 12 = 1/4 x 12 = 3 km.

An expression has numbers, variables, and mathematical operations. The factors of the expression 4x³+x²-8x-2 by grouping are x²(4x+1)-2(4x+1).

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The factors of the expression by grouping can be done as,

[tex]4x^3+x^2-8x-2[/tex]

Take x² as the common factor from the first two terms while -2 from the last two terms,

[tex]4x^3+x^2-8x-2\\\\=x^2(4x+1)-2(4x+1)[/tex]

Thus, the factors of the expression 4x³+x²-8x-2 by grouping are x²(4x+1)-2(4x+1).

Answer:

139 ft³

Step-by-step explanation:

Diameter of the cylinder is 3 ft. Therefore, the radius is 1.5 ft

Volume of the cylinder = πr²h

= 3 × 1.5 × 1.5 × 4

= 27 ft³

Volume of the cuboid (rectangular prism) = lbh

= 7×4×4

= 112 ft³

Volume of the figure = 112 + 27 = 139 ft³

Step-by-step explanation:

Explanation:

We have y = -0.9x^2 + 76x - 250 which is in the form y = ax^2+bx+c

where,

The vertex (h,k) is when the profit is maxed out.

h = -b/(2a)

h = -76/(2(-0.9))

h = 42.222 approximately

Let's plug in x values around x = 42

Try x = 41

y = -0.9x^2 + 76x - 250

y = -0.9(41)^2 + 76(41) - 250

y = 1353.10

Now try x = 42

y = -0.9x^2 + 76x - 250

y = -0.9(42)^2 + 76(42) - 250

y = 1354.4

Now try x = 43

y = -0.9x^2 + 76x - 250

y = -0.9(43)^2 + 76(43) - 250

y = 1353.9

We see that the largest profit happens when x = 42.

The rational expression for the ratio between the perimeter and the area is:

R = 4/3x

We want to find the ratio, as a rational expression, between the perimeter and the area.

Remember that for a square of sidelength S, the perimeter is:

P = 4*S

And the area is:

A = S^2

Then the ratio between these two is:

R = P/A = (4*S)/(S^2) = 4/S

In this case, the sidelength is 3x, then S = 3x, replacing that we get:

R = 4/3x

Using proportions, it is found that the unit rate is of 1.33 cups of brown sugar for a batch of cookies.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

2/3 cups of brown sugar are used for half a batch of cookies. The unit rate is the amount used for one batch. Hence, the rule of three is given by:

2/3 cups - 1/2 batch

x cups - 1 batch.

Applying cross multiplication:

[tex]\frac{1}{2}x = \frac{2}{3}[/tex]

[tex]x = \frac{4}{3}[/tex]

The unit rate is of 1.33 cups of brown sugar for a batch of cookies.
