Answer:
m = 2k/v
Step-by-step explanation:
Identify the coefficient of m (v/2) and multiply by its inverse (2/v).
(2/v)k = (2/v)m(v/2) . . . . multiply both sides of the equation by 2/v
2k/v = m . . . simplify
m = 2k/v
Answer:
105 cc of 7% solution
245 cc of 17% solution
Step-by-step explanation:
If x = volume of 7% solution, and y = volume of 17% solution, then:
x + y = 350
0.07x + 0.17y = 0.14(350)
Solve with substitution:
0.07x + 0.17(350 − x) = 0.14(350)
0.07x + 59.5 − 0.17x = 49
10.5 = 0.10x
x = 105
y = 245
Answer:
A. 5
Step-by-step explanation:
just use calculator tbh
In 1997 = 17697
Because, each year, the number of employees is expected to decrease by 2.2%, find 2.2% of 17697 and subtract from the number.
2.2/100 x 17697 = 38933.4/100 = 389.334
^that was calculating 2.2% of 17697. Now we subtract:
17697.000
- 389.334
17307.666 =
Round to the nearest whole number = 17308
Answer: in 1998, the expected number of workers is 17308
