Can someone check over these math problems that I did? Please?

1. The bloodhound, a type of dog, has 4.0 X 10^9 (10 to the ninth power) scent receptors in its nose. A human has 1.2 X 10^7 scent receptors. How many times more scent receptors does a bloodhound have than a human. round to nearest whole number. ---------- I got 333 is that right?
2.
Last year, 65 pounds of hamburger patties were cooked to serve between 250 and 300 people. this year the school expects between 325 and 375 people. Estimate the number of patties needed for this year? ----- I'm really not sure on this one but I got 81 lbs but it does seem right!???

3. To make maple syrup, Kyle must boil 40 gallons of maple tree sap to produce one gallon of syrup. Ken sells his maple syrup in containers that hold one quart. At that rate, how many gallons of maple tree sap must be boiled to make one quart of syrup?----I got 160 gallons

4. Kyle collects sap in a cylindrical bucket having a diameter of 10 inches. If the bucket is filled with maple sap to a depth of 5 inches, how many gallons of sap does it contain? Give your answer to the nearest tenth of a gallon. USE ! GALLON = 231 CUBIC INCHES AND USE 3.14 FOR PIE------I got 1.7

1. To find out how many times more scent receptors a bloodhound has compared to a human, divide the number of scent receptors in the bloodhound's nose by the number of scent receptors in a human's nose:

(4.0 X 10^9) / (1.2 X 10^7) = 333.333

Since we are rounding to the nearest whole number, the bloodhound has approximately 333 times more scent receptors than a human.

2. To estimate the number of hamburger patties needed for this year, we can find the average number of patties needed per person for last year and use that to estimate for this year.

Average number of patties per person last year = 65 lbs / 275 people = 0.236 lbs/person

Estimated number of patties needed for this year = (0.236 lbs/person) x 350 people = 82.6 lbs

Rounded to the nearest whole number, approximately 83 pounds of hamburger patties are needed for this year.

3. To find out how much maple tree sap needs to be boiled to make one quart of syrup, we need to convert gallons to quarts.

1 gallon of maple tree sap = 4 quarts
40 gallons of maple tree sap = x gallons of syrup

So, x = 40 gallons x 4 quarts/gallon = 160 quarts of syrup

Therefore, 160 gallons of maple tree sap must be boiled to make one quart of syrup.

4. To find out how many gallons of sap a cylindrical bucket contains, we need to calculate the volume of the bucket.

Volume of a cylinder = π * (radius)^2 * height

Given:
Diameter of the bucket = 10 inches
Radius (r) of the bucket = diameter / 2 = 10 inches / 2 = 5 inches
Height (h) of the sap in the bucket = 5 inches

Volume of sap = π * (5 inches)^2 * 5 inches
Volume of sap = 3.14 * 25 square inches * 5 inches
Volume of sap = 392.5 cubic inches

To convert cubic inches to gallons, divide by 231 (since 1 gallon = 231 cubic inches):

Volume of sap in gallons = 392.5 cubic inches / 231 cubic inches/gallon = 1.7 gallons

Therefore, the bucket contains approximately 1.7 gallons of sap.

Sure! Let's go through each problem one by one and check your answers.

1. The bloodhound has 4.0 X 10^9 scent receptors, and a human has 1.2 X 10^7 scent receptors. To find out how many times more scent receptors a bloodhound has than a human, we need to divide the number of scent receptors in the bloodhound's nose by the number in a human's nose:

(4.0 X 10^9) / (1.2 X 10^7) ≈ 333,333,333.33

So, the bloodhound has approximately 333,333,333 times more scent receptors than a human. Rounded to the nearest whole number, that would be 333,333,333, not 333. Therefore, your answer of 333 is not correct.

2. Last year, 65 pounds of hamburger patties were cooked for 250 to 300 people. This year, the school expects between 325 and 375 people. To estimate the number of patties needed for this year, let's find the average number of people and use that to calculate the patties:

- Average number of people: (325 + 375) / 2 = 350
- Average number of patties per person: 65 pounds / 275 people = 0.236 pounds per person
- Number of patties needed: 0.236 pounds/person x 350 people = 82.6 pounds

Rounded to the nearest whole number, the estimated number of patties needed for this year would be 83 pounds. Your answer of 81 pounds is close, but not correct.

3. To make one gallon of maple syrup, Kyle must boil 40 gallons of sap. Ken sells his syrup in containers that hold one quart. We need to find out how many gallons of sap are needed to make one quart of syrup:

- Number of quarts in a gallon: 4 (since there are 4 quarts in a gallon)
- Number of gallons of sap needed for one quart of syrup: 40 gallons / 4 quarts = 10 gallons

Therefore, your answer of 160 gallons is not correct.

4. Kyle collects sap in a cylindrical bucket with a diameter of 10 inches. If the bucket is filled to a depth of 5 inches, we need to calculate how many gallons of sap it contains using the conversion factor given:

- Radius of the bucket: 10 inches / 2 = 5 inches
- Volume of a cylinder: π * r^2 * h
- Volume of sap in the bucket: 3.14 * (5 inches)^2 * 5 inches = 392.5 cubic inches
- Number of gallons: 392.5 cubic inches / 231 cubic inches per gallon ≈ 1.7 gallons

Your answer of 1.7 is correct!

To summarize, your correct answers are:
1. The bloodhound has approximately 333,333,333 more scent receptors than a human.
2. The estimated number of patties needed for this year is 83 pounds.
3. To make one quart of syrup, 10 gallons of sap must be boiled.
4. The cylindrical bucket contains approximately 1.7 gallons of sap.
