Answer:
You have a 0.8 / 80% of NOT picking the blue marbles.
Step-by-step explanation:
5 + 7 + 3 = 15
15 - 3 = 12
12 / 15 = 0.8 = 80%
Answer:
492.99
Step-by-step explanation: x = amount invested at 12%
y = amount invested at 9%
---
x + y = 20287
0.12x = 0.09y + 492.99
---
put the system of linear equations into standard form
---
x + y = 20287
0.12x - 0.09y = 492.99
Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
----> one year is equal to 12 months
substitute in the formula above
The correct answer is B) 1/2 mL.
Adding the amounts that are currently in each beaker, we have:
1/8 + 1/4 + 3(3/8) + 2(3/4) + 1
= 1/8 + 1/4 + 9/8 + 6/4 + 1
Converting all of these to fractions with common denominators, we have:
1/8 + 2/8 + 9/8 + 12/8 + 8/8 = 32/8 = 4 mL of liquid total.
We have 8 beakers to split up 4 mL of liquid; 4/8 = 1/2.
