Mrs. Epps buys 500 bags of balloons for the high school prom for $250. What is the cost per bag?
The cost per bag is $0.50.
To figure this out, you can divide the total cost ($250) by the number of bags (500):
$250 ÷ 500 = $0.50
A man that is 6 feet tall weighs 165 pounds. Use this information to predict the weight of a man that is 5 1/2
feet tall.
We can use proportions to make this prediction.
Let's start by converting the height of the first man, who is 6 feet tall, to inches:
6 feet = 72 inches
Now we need to set up a proportion using the two men's heights:
72 inches / 165 pounds = 66 inches / x pounds
Here "x" represents the weight of the second man, who is 5 1/2 feet tall.
To solve for "x," we can cross-multiply:
72 inches * x pounds = 165 pounds * 66 inches
Now we can divide both sides by 72 inches to isolate "x":
x pounds = (165 pounds * 66 inches) / 72 inches
x pounds = 151.25 pounds
So our prediction is that a man who is 5 1/2 feet tall will weigh approximately 151.25 pounds.
In the function y = 0.25x + 3.5, y represents the cost of a gallon of milk after a certain number of years, x. How much does the cost of milk increase every year?
The cost of milk increases by $0.25 every year according to the function.
The coefficient of "x" in the function represents the rate of change, which is the amount that y changes for every one unit of x. In this case, the coefficient of "x" is 0.25, which means that for every one year that passes (one unit of x), the cost of milk (y) increases by $0.25.
So the answer is that the cost of milk increases by $0.25 per year.
Angie can peel 1/6
of a crate of potatoes every 1/18
of a hour. Compute the unit rate.
To compute the unit rate, we need to determine how many units of potatoes Angie can peel per hour. We can do this by simplifying the given fractions and dividing the amount of potatoes peeled by the time it takes:
1/6 ÷ 1/18
To divide by a fraction, we can multiply by its reciprocal:
1/6 ÷ 1/18 = 1/6 × 18/1 = 18/6 = 3
So Angie can peel 3 units of potatoes per hour. We don't know the exact unit of measurement for the "crate" of potatoes, but we can say that she can peel 3 crates per hour if the fractions represent equal amounts of potatoes.
a game involves spinning this spinner. what is the probability of the pointer landing on y
A circle is divided equally into eight sections.
Since the circle is divided equally into eight sections, and we want to find the probability of the pointer landing on "y," and it occupies a single section, the probability of the pointer landing on "y" is:
1 section out of 8 sections = 1/8
So the probability of the pointer landing on "y" is 1/8 or 0.125 as a decimal.
To find the cost per bag, we need to divide the total cost by the number of bags. In this case, Mrs. Epps bought 500 bags of balloons for $250. So, to calculate the cost per bag, we divide the total cost ($250) by the number of bags (500):
Cost per bag = Total cost / Number of bags
Cost per bag = $250 / 500
To calculate this, we simply divide 250 by 500:
Cost per bag = $0.50
Therefore, the cost per bag of balloons is $0.50.
