You have 8 gallons of lemonade to sell. You use cone-shaped cups that are 9 centimeters in diameter and 12 centimeters tall. Eac
andre [41]

You will need 119 cups to sell all of the lemonade.

Step-by-step explanation:

Given,

Diameter of cups = 9 cm

Radius of cup = \frac{Diameter}{2}=\frac{9}{2}=4.5\ cm

Height of cups = 12 cm

We will find volume of cup.

Volume = \frac{1}{3}\pi r^2h\\

Putting all the values

Volume=\frac{1}{3}(3.14)(4.5)^2(12)\\\\Volume=\frac{1}{3}(3.14)(20.25)(12)\\\\Volume= \frac{763.02}{3}\\\\Volume= 254.34\ cm^3

Therefore;

Each cup can hold 254.34 cubed centimeter of lemonade.

Number of gallons = 8

1 gallon = 3785 cm³

8 gallons = 3785*8 = 30280 cm³

Let,

x = Number of cups

Volume of lemonade in one cup * Number of cups = Volume of 8 gallons

254.34x=30280

Dividing both sides by 254.34

\frac{254.34x}{254.34}=\frac{30280}{254.34}\\x=119.05

Rounding off to nearest whole number

x = 119

You will need 119 cups to sell all of the lemonade.

Richard simplified an expression in three steps, as shown:
soldi70 [24.7K]

Answer:

Step 2 because Richard multiply the powers of same base  in denominator instead adding powers  of same base.

Step-by-step explanation:

We are given that Richard simplified an expression in threes steps

We have to find the incorrect step in simplification of Richard

Step 1: all the exponent are multiplied by 3

\frac{x^{-4}y^2}{yx^2\cdot x^2y^{-4}}^{3}=\frac{x^{-12}y^6}{y^3x^6\cdot x^6y^{-12}}

Step 2:The exponents in the denominator are multiplied

\frac{x^{-12}y^6}{y^3x^6\cdot x^6 y^{-12}}=\frac{x^{-12}y^6}{x^{12}y^{-9}}

Step 3:The exponents of the same base are subtracted during division

\frac{x^{-12}y^6}{x^{12}y^{-9}}=x^{-12-12}y^{6+9}

=x^{-24}y^{15}

Richard makes mistake in step 2 when we multiply  then power of same base should be added but Richard multiply the powers of same base  in denominator.

Find the product 3x ( 5x +8y)
notka56 [123]

Answer:

x = 3.5y

Step-by-step explanation:

Simplifying

3x + 8y + -5x + -1y = 0

Reorder the terms:

3x + -5x + 8y + -1y = 0

Combine like terms: 3x + -5x = -2x

-2x + 8y + -1y = 0

Combine like terms: 8y + -1y = 7y

-2x + 7y = 0

Solving

-2x + 7y = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-7y' to each side of the equation.

-2x + 7y + -7y = 0 + -7y

Combine like terms: 7y + -7y = 0

-2x + 0 = 0 + -7y

-2x = 0 + -7y

Remove the zero:

-2x = -7y

Divide each side by '-2'.

x = 3.5y

Simplifying

x = 3.5y
