1. 10cm^3 of a normal specimen of human blood contains 1.2g of hemoglobin. How many grams does 21cm^3 of the?

Question

same blood contain?

2. It is known that making 1lb. of honey requires 20,000 trips by bees to flowers to gather nectar. How many pounds of honey would 65,000 trips produce?

3. Last season a major league baseball player got 140 hits in 200 times at bat. If the player expects to bat 500 times in the entire season with the same ratio of hits to at bats, how many hits can the player expect to have?

4. A sample of 142 firecrackers contained 5 duds. How many duds would you expect in a sample of 2698 firecrackers?

5. Find the variation constant and an equation of variation where y varies directly as x and y=54 when x=6

Answer 1

1. this is a proportion.

21/10 * 1.2= 2.52 gm

2. 65000/20000 * 1 = 3.25 ib

3. 140 / 200 = 0.7 rate
0.7 * 500= 350 times

4. 2698/142 * 5 = 95 duds

5. y = k * x
k= y/x = 9

Answer 2

If I answer these correctly will I go on the show, 'Are You Smarter Than A Fourth Grader?' Okay:
1. Divide 1.2 by 10, then multiply this answer by 21
2.Divide 65000 by 20000,(or 65.00 by 20.00), multiply the answer times 1LB.
3.Multiply 70 times 5 =the ratio of hits to at bats can be derived from this
4.Divide 2698 by 142, then multiply the answer times 5
5.All the above are supposed to be done with an algebraic formula, the one/s you have studied recently. This one is the last formula you probably had in class today. Good luck, Chickster.

Answer 3

This is fourth grade stuff. Do you need help with this? If you do then you need help.

Answer 4

Naughty, naughty. Do your own homework.
