the volume of an ice cream cone is 12 pi cubic cm. if the height is 9 cm, what is the diameter of the cone ?

Answer:

192

Step-by-step explanation:

The balance in a bank account after 3 years with an initial deposit of $1600 and an annual interest rate of 4% is calculated using the simple interest formula. The result is a balance of $1792 after adding the interest earned to the principal amount.

The question involves finding the balance in a bank account after 3 years with an initial deposit of $1600 and an annual interest rate of 4%. This is a mathematics problem that involves the concept of simple interest.

To calculate the balance after 3 years, we can use the formula for simple interest:

Balance = Principal + (Principal × Rate × Time)

Where:

Using this information, the calculation is as follows:

Balance = $1600 + ($1600 × 0.04 × 3)

Balance = $1600 + $192

Balance = $1792

Therefore, after 3 years, the balance in the bank account would be $1792.

Answer:

31.2

Step-by-step explanation:

Ratio shows us the number of times a number contains another number. The weight of the fruit box is 31.2 lbs.

A ratio shows us the number of times a number contains another number.

As it is given the ratio of the fruits oranges, apples, and pears is 2:5:6. And the weight of the oranges in the box is 4.8 lbs.

Let's assume that the weight of the oranges, apples, and pears is 2x, 5x, and 6x respectively.

Now, as the weight of the oranges is 4.8 lbs, therefore,

The weight of the oranges, 2x = 4.8 lbs

                                                 x = 2.4 lbs

Now, as we know the value of x, therefore, the weight of the fruit box is,

[tex]\begin{aligned}\text{Total weight of the fruit box} &= 2x + 5x+ 6x \\&=13x \end{aligned}[/tex]

Now, substitute the value of x, therefore, we can write it as,

                                             [tex]=13x\\\\= 13(2.4)\\\\= 31.2\rm\ lbs[/tex]

Hence, the weight of the fruit box is 31.2 lbs.

-91w + 60

Step-by-step explanation:

to simplify this -10(10w-6-w)-w

we have,

-10(10w-6-w)-w

-100w + 60 + 10w - w

-91w + 60

To solve for x and find the measure of each angle, set up the equation (3x-45) + (2x + 15) = 90, combine like terms, and solve for x. Then, substitute the value of x back into the expressions for angle M and P to find their measure.

To solve for the value of x and find the measure of each angle, we'll use the fact that complementary angles add up to 90 degrees. So, we can set up the equation: (3x-45) + (2x + 15) = 90.

Now, let's solve for x:

3x - 45 + 2x + 15 = 90

Combine like terms: 5x -30 = 90

Add 30 to both sides: 5x = 120

Divide both sides by 5: x = 24.

Substitute the value of x back into the expressions for angle M and P to find their measure:

Angle M = (3(24) - 45) = 57 degrees

Angle P = (2(24) + 15) = 63 degrees

https://brainly.com/question/15592900

#SPJ12

Final answer:

Angles M and P are complementary, summing to 90 degrees. By setting up the equation (3x - 45) + (2x + 15) = 90 and solving for x, we find that x = 24, angle M measures 27 degrees, and angle P measures 63 degrees.

Explanation:

To solve for the value of x when angles M and P are complementary, we need to set up an equation based on the fact that the sum of complementary angles is 90 degrees. Therefore, we can write the equation as the sum of both angles: (3x - 45) + (2x + 15) = 90. After combining like terms and solving for x, we can find the measure of each angle by substituting the value of x back into the original expressions for angle M and angle P.

Write the equation for complementary angles: (3x - 45) + (2x + 15) = 90

Simplify and combine like terms: 5x - 30 = 90

Add 30 to both sides: 5x = 120

Divide by 5: x = 24

Find the measure of angle M: M = 3x - 45 = 3(24) - 45 = 27 degrees

Find the measure of angle P: P = 2x + 15 = 2(24) + 15 = 63 degrees

Thus, the value of x is 24 degrees, angle M measures 27 degrees, and angle P measures 63 degrees.

Final answer:

To find the percent of sales donated to hospitals, divide the amount donated ($286) by the total sales ($7,150) and multiply by 100, resulting in 4%.

Explanation:

The question asks to calculate what percent of the total sales was donated to the hospitals by the shoe store. To find this, we use the basic formula for calculating percent: part over total, times one hundred, equals percent. In this case, the part is the amount donated ($286) and the total is the total sales ($7,150).

So, the calculation would be: (286 / 7,150) x 100 = 4%. Thus, the shoe store donated 4% of its total sales to hospitals.

Answer:

The answer is 7/36.

Step-by-step explanation:

First, you find out how many possible outcomes there are from rolling a pair of dice. On one cube, you can roll a 1,2,3,4,5, or 6; so there are 6 outcomes. Since there are two cubes, you multiply 6 by itself to get a total of 36 possible outcomes. Next, you find the probability of the sum of the numbers rolled being an even number; the possibilities are 2,4,6,8,10, or 12, which is 6/36. The probability of rolling a multiple of 5; the one possibility is just 5, since we already accounted for rolling a 10 as an even number. So that is 1/36. The word or says that we add the two probabilities, so the final answer is 6/36+1/36=7/36.

Answer:

2/6 = 1/3

Step-by-step explanation:

you have a six sided dice. 2 numbers over the entire dice numbers so that would be, 2/6 which simplifies to 1/3

Have a great day!

The probability of rolling either a 3 or a 5 on a single roll of a fair six-sided die is 1/3.

To calculate the probability of rolling either a 3 or a 5 with a single roll of a six-sided die, we need to consider that there are 6 possible outcomes (the numbers 1 through 6). Since each face has an equal chance of landing face up, each single number has a probability of 1/6. When calculating the probability of rolling a 3 or a 5, we add the probabilities of these two separate events together because they are mutually exclusive outcomes.

The probability of rolling a 3 is 1/6, and the probability of rolling a 5 is also 1/6. Thus, the probability of rolling either a 3 or a 5 is given by:

(Probability of rolling a 3) + (Probability of rolling a 5) = 1/6 + 1/6 = 2/6

After simplification, the probability in its simplest form is:

The first distribution with numbers ranging from 1 to 12 has a mean of 6.5, while the second distribution with numbers from 101 to 112 has a mean of 105.5. It is therefore True that the first distribution has a smaller mean than the second distribution.

The question asks whether the first distribution (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) has a smaller mean than the second distribution (101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112). To determine this, we will calculate the mean of both distributions.

The mean of a distribution is calculated by adding all the numbers in the set and then dividing by the count of numbers.

For the first distribution:
Mean = (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12) / 12
Mean = 78 / 12
Mean = 6.5

For the second distribution:
Mean = (101 + 102 + 103 + 104 + 105 + 106 + 107 + 108 + 109 + 110 + 111 + 112) / 12
Mean = 1266 / 12
Mean = 105.5

Comparing the means of both distributions, the first distribution has a mean of 6.5 and the second distribution has a mean of 105.5. Therefore, it is True that the first distribution has a smaller mean than the second distribution.

Furthermore, this corresponds to elementary properties of means where adding the same value to all elements of a distribution shifts the mean but does not affect the comparison of means of two distributions if the same value is added to each distribution.

The exact volume of the cylinder with a 10 ft diameter and 8 ft height is found using the formula V = πr²h. With a diameter of 10 ft, the radius is 5 ft. The calculated volume is 628.318 cubic feet.

To find the exact volume of a cylinder with a diameter of 10 ft and a height of 8 ft, we can use the following formula:

V = πr²h

Where V is the volume, r is the radius of the cylinder (half of the diameter), h is the height, and π (pi) is approximately 3.14159. Since the diameter is given as 10 ft, the radius will be 5 ft (half of the diameter).

Substituting our values into the formula gives us:

V = π × (5 ft)² × 8 ft

V = 3.14159 × 25 ft² × 8 ft

V = 3.14159 × 200 ft³

V = 628.318 ft³

Therefore, the exact volume of the cylinder is 628.318 cubic feet.

Answer:

240000

Step-by-step explanation:

To model the growth of a savings account with an exponential function, we will use the formula to calculate the amount of money, A(t), accumulated after a certain number of years, t, given an initial principal amount, P, and an annual interest rate, r.

The standard formula for exponential growth in the context of compound interest is as follows:

\[ A(t) = P (1 + r)^t \]

where:
- \( A(t) \) represents the amount of money in the savings account after \( t \) years.
- \( P \) is the principal amount initially deposited into the account.
- \( r \) is the annual interest rate (expressed as a decimal).
- \( t \) represents the time in years.

For your savings account, you start with $400 (the principal amount, \( P \)), and it gains 3% interest every year (the annual interest rate, \( r \)).

Let's assign the given values to their respective variables in the formula:

- \( P = \$400 \)
- \( r = 3\% = 0.03 \) (since 3% as a decimal is 0.03)
 
Inserting these values into the formula yields the specific exponential function for this savings account:

\[ A(t) = \$400 (1 + 0.03)^t \]

This equation represents the amount of money that will be in the savings account after any number of years, \( t \), based on the continuous application of a 3% annual interest rate.
