Answer:
a = -21 and b = 15
Step-by-step explanation:
It is given a matrix multiplication,
<u>To find the value of a and b
</u>
It is given that,
| 6 -5 | * | -1 | = | a |
|-3 4 | | 3 | | b |
We can write,
a = (6 * -1) + (-5 * 3)
= -6 + -15
= -2
1
b = (-3 * -1) + (4 * 3)
= 3 + 12
= 215
Therefore the value of a = -21 and b = 15
6L = 6,000ML
54,000ML = 54L
Answer:
b
Step-by-step explanation:
convert 2 1/2 hours into minutes to be easier to work with
15 / 150 = 10 minutes
every 10 minutes he pots a plan.
there are 210 minutes in 3 1/2 hours
210 / 10 = 21
Answer:
165000
Step-by-step explanation:
simple interest
PV(1+it)
150000(1+5*.02)
=165000
if you need it then the interest earned would just be 165000-150000= 15000
