In the morning, a farm worker packed 3 pints of strawberries every 4 minutes. In the afternoon, she packed 2 pints of strawberries every 3 minutes. What was the difference between her morning and afternoon packing rates, in pints per hour?

A. 5
B. 10
C. 40
D. 45

Answers

A. 5
her morning packing rate was 45 pints per hour.
her afternoon packing rate was 40 pints per hour.

Edit:
By dividing 60 by 4, you get 15, so multiply 15 by 3, this gives you 45.
By dividing 60 by 3, you get 20, so multiply 20 by 2, this gives you 40
3 pints every 4 minutes = ? pints every 60 minutes.
2 pints every 3 minutes = ? pints every 60 minutes.

For the first one, just divide 60/4. That is 15. 15*3 = 45, so 45 pints every hour.

Do the same process for the second equation. (60/3) * 2 = 40

Finally, 45-40=5.

The answer is A.

a candy machine contains 120 spherical kids each candy is solid and has diameter of 0.25 in what is the total volume of the candies in the machine

Answers

Final answer:

The total volume of the candies in the machine is approximately 0.981 cubic inches.

Explanation:

To find the total volume of the candies in the machine, we first need to calculate the volume of one candy. The diameter of each candy is 0.25 inches, so the radius is half of the diameter, which is 0.125 inches. The formula for the volume of a sphere is V = (4/3)πr³. Plugging in the values, we get V = (4/3)π(0.125)³ = 0.0081777 cubic inches.

Since there are 120 candies in the machine, we can multiply the volume of one candy by the number of candies to get the total volume. Total Volume = 120 * 0.0081777 = 0.981324 cubic inches.

The number 50 is no more than a number h times 2

Answers

That depend what #uou plug in for the variable h

The statement 'The number 50 is no more than a number h times 2' is an algebraic inequality stating that 50 is less than or equal to 2h. To solve for h, we divide 50 by 2, yielding h must be greater than or equal to 25.

The question "The number 50 is no more than a number h times 2" relates to a basic algebraic concept where we represent numbers or quantities using variables. The statement can be translated into an inequality that states 50 is less than or equal to 2 times a number h, or mathematically, 50 <= 2h. This could be solved for h by dividing both sides of the inequality by 2, resulting in h >= 25.

Ken is a tour guide at an art museum. He earns $11 an hour regular pay and receives time-and-a-half for overtime. Last week he worked 40 hours plus overtime. If he made $66.00 in overtime, how many overtime time hours did he work?

Answers

He earns $16.50 for one hour of overtime.
He worked 4 hour of overtime.
I figured this out by first finding out how much he earns in one overtime so that equals $16.50. Then you need to divide $66.00 by $16.50 to get 4.

Answer:

Ken worked 4 hours overtime.

Step-by-step explanation:

Ken earns $11 for an hour in his regular pay.

He receives time-and-a-half for overtime =  $11 + (11/2) = 11 + 5.50 = $16.50

Ken worked 40 hours plus overtime and he made $66.00 in his overtime.

So he worked overtime = $66.00 ÷ 16.50 = 4 hours

Ken worked 4 hours overtime.

Kyle and his brother have a marble set. Of the marbles, 12 are blue. This represents 50/100 of all the marbles. What decimal is equivalent to 50/100

Answers

The decimal equivalent to 50/100 is 0.50, which is found by dividing 50 by 100.

The decimal equivalent to 50/100 is 0.50. This is because 50/100 is the same as dividing 50 by 100, which gives you 0.50.

This conversion is a standard way of expressing fractions where the denominator is 100, and it's commonly used to convert fractions into percentages or decimals.

For example, to convert 1/4 to a percent, you multiply by 25 (since 4 times 25 equals 100) to get 25 percent, which is equivalent to the decimal 0.25.

So, 50/100 is equivalent to 0.5 as a decimal.

The Marriott family bought a new apartment three years ago for $65,000. The apartment is now worth $86,515. Assuming a steady rate of growth, what was the yearly rate of appreciation?

Answers

Final answer:

The annual appreciation rate for the Marriott family's apartment they bought three years ago for $65,000, now worth $86,515, is 10%.

Explanation:

The subject matter of this question is the calculation of the appreciated rate of the Marriott family's apartment. They bought this apartment three years ago for $65,000, and now it is worth $86,515. We want to find a constant rate of growth over these three years.

To determine the annual rate of appreciation, we need to use the formula for exponential growth: final value = initial value × (1 + annual growth rate) ^ number of years.

Let's plug in the given values: $86,515 = $65,000 × (1 + growth rate)³.

First, we divide the final value by the initial value: $86,515/$65,000 = 1.33177.

Second, we must calculate the cubic root of 1.33177 (since we have three years), which is 1.1. Therefore, the annual growth rate is 1.1 - 1 = 0.1 or 10%.

Hence, the yearly rate of appreciation for the apartment is 10%.

We know that angles on a straight line sum to 180°, and we can see that 90° has already been defined on the left top left hand, leaving us with 90° on the top right hand. We are given 47°, so that must mean that the angle between the right angle and the 47° angle is:

Opposite angles around a 360° point are equal, and we see that angle x is opposite the 43° that we just found out. Therefore, x= 43°

victor has the map scale missing.he knows the distance from the lake to the youth center is 8 miles. on the map they are 2in. apart. what is the scale for victors map

Answers

The correct scale is 1 in = 4 mi.

Explanation:

The scale tells us what a given measurement on the map equals in real-life distance.  

The measurement on the map that we have is 2 inches, and it equals 8 miles:

2 in = 8 mi

This can also be written as 2/8.  This fraction can be simplified, since both 2 and 8 are divisible by 2; it will simplify to 1/4.  This is the same as 
1 in = 4 mi.

Answer:

The correct scale is 1 inch = 4 miles.

Step-by-step explanation:

Map scale is defined as the ratio between the marked distance on a map to  the corresponding distance on the ground.

Here, it is given that the measurement on the map is 2 inches, and it equals to 8 miles; so 2 inches = 8 miles

Simplifying this we get:

1 inch = 4 miles.

Hence, the scale is 1 inch equals 4 miles.

at a local gas station, regular gasoline sells for $2.899 per gallon, while premium gasoline sells for $3.379 per gallon. how much does a person save on 15.25 gallons of gas by buying regular instead of premium?

Answers

the person saved $7.32
We first need to find what each type of gasoline equals at 15.25 gallons.
Regular Gasoline:
2.899•15.25
44.20975
Premium Gasoline:
3.379•15.25
51.52975
Let’s subtract regular from premium to see how much you would save.
51.52975-44.20975
7.31975
So you would save $7.31975 when buying regular gas instead of premium.

How do I find the prime factorization of 40? And what is prime factorization?

Answers

Prime factorization is a way of showing which prime numbers (numbers that can only be divided by one and itself) can go into a number. For instance, the prime factorization of 4 would be 2 x 2. Two can only be divided by one and itself, so it is a prime number, and 2 x 2 = 4. For larger numbers, divide by a prime number until the number that is being divided is a prime number. Each divisor will be used as part of the prime factorization. The final dividend will also be used. Add the dividend, order each divisor from least to greatest, and then you're done. Therefore, the prime factorization of 40 would be 2 x 2 x 2 x 5.
Final answer:

Prime factorization is finding the prime numbers that multiply to create the original number. The prime factorization of 40 is 2³ × 5.

Explanation:

Prime factorization is the process of breaking down a composite number into the prime numbers that, when multiplied together, give the original number. To find the prime factorization of 40, you would start by finding two numbers that multiply to give you 40. You could start with 4 × 10. Since 4 is not a prime number, it can be further broken down into 2 × 2. The number 10 can also be broken into prime factors 2 × 5. Therefore, the prime factorization of 40 is 2 × 2 × 2 × 5, or 2³ × 5.

Rewrite the following equation in slope-intercept form. 6x − 14y = -3 Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:
y = (3/7) x + (3/14)

14y = 6x + 3
y = (6/14)x + (3/14)
y = (3/7) x + (3/14)
