The formula for a cone is pi * r^2 * (h/3) or pi* r^2 * h * 1/3.

Since the height is 7ft and the radius if 4ft you plug those into the equation and get:

V= 1/3 * pi * (4^2) * (7)ft cubed which is the answer of B

By definition, the volume of a cone is given by:

V = (\frac{1}{3}) * \pi * r ^ 2 * h

Where,

r: cone radius

h: height of the cone

Substituting values in the given equation we have:

V = (\frac{1}{3}) * \pi * (4) ^ 2 * (7)

Using this last expression, we can find the volume of the cone.

Answer:

The volume of the cone is given by the following expression:

V = (\frac{1}{3}) * \pi * (4) ^ 2 * (7)

Heidi's Accessories bought 50 necklaces for $10 each on account. The invoice included a 6% sales tax and payment terms of 2/10,
garri49 [273]

Answer:

<u>The correct answer is B. Accounts payable for US$ 53.oo</u>

Step-by-step explanation:

1. Let's recall what is the Journal entry when a company return part of the inventory previously purchased:

Debit

The amount Heidi's accessories owed to the supplier would have been sitting as a credit on the accounts payable account because the invoice has not been payed. In the case of this return, we should debit it because we should diminish the amount due.

Credit

The goods Heidi's accessories are returning and therefore, the asset of inventory decreases. The credit to purchase returns reduces the value of the total purchases. That's why options C and D are incorrect.

2. Now, let's calculate the amount of the return that Heidi's accessories made, this way:

Return = Number of necklaces * Price of each necklace + Sales taxes

Replacing with the real values, we have:

Return = 5 * 10 + (5 * 10) * 0.06

Return = 50 + (50) * 0.06

Return = 50 + 3 = 53

<u>The correct answer is B. Accounts payable for US$ 53.oo</u>

kolezko [41]

Answer:

(c) H0 should be rejected

Step-by-step explanation:

Null hypothesis (H0): population mean is equal to 5

Alternate hypothesis (Ha): population mean is greater than 5

Z = (sample mean - population mean) ÷ (sd/√n)

sample mean = 5.3, population mean = 5, sd = 1, n = 500

Z = (5.3 - 5) ÷ (1/√500) = 0.3 ÷ 0.045 = 6.67

Using the normal distribution table, for a one tailed test at 0.01 significance level, the critical value is 2.326

Conclusion:

Since 6.67 is greater than 2.326, reject the null hypothesis (H0)

Which of the fractions is in lowest terms and is equivalent to -1.25
hjlf

Answer:

  The lowest terms equivalent to - 1.25  =  - \frac{5}{4}

Step-by-step explanation:

- 1.25 = - 1\frac{25}{100}

         = - ( 1 × 100 +25) ÷ 100

         =  -( \frac{125}{100} ) × (\frac{5}{5}

        =  - \frac{25}{20}

        =  - (\frac{25}{20}) × (\frac{5}{5}

        =  - \frac{5}{4}
