1.) What value(s) of t satisfy the following equation: 8t/3-2/3 2.) Put the following into scientific notation a.) 235,000 b.) 0.000337 3.) Take the following out of scientific notation: a.) 4.79x10 b.) 6.34x10 4.) Perform the following operations: a.)-log(2.35x10) 5.) Perform the following operations a-4-6 c.-4+6= 6.) What value of s satisfies the following equation? 12s-(4s-6) = 3s-(9s-27) 7.) How many seconds are there in one decade (10 years)? 315, 30o60 8.) The sum of the ages of two boys is 18. If 4 times the younger boy's age is subtracted from 3 times the older boy's age, the difference is 12. What are the ages of the two boys? 9.) Given that D=m/V and Q = mhe, solve the following word problem: Determine Hr if D-4, V- 18, and Q= 40,000. 10.) A certain type of bean has an average mass of 2 grams per bean, a bag of beans holds about 2000 beans, and a crate holds 40 bags. If a load placed on the back of a truck has a mass of 4000 kg, how many crates of beans are on the truck? (Note: 1 kg 1000 g)

Explanation / Answer

(1)

Solving we get:

t = (2/3)*(3/8) = 0.25

(2)

235000 = 2.35E05

0.000337 = 3.37E-4

(3)

4.79*106 = 4790000

6.34*10-3 = 0.00634

(4)

-log(2.35*10-2) = 2-log(2.35) = 1.629

10-3.25 = 0.000562

Hope this helps !
