1.53 hours if she drove 40 mph it would be 1 hour
7x + 6y = 21 ⇒ 7x + 6y = 21
1x + 3y = -12 ⇒ 2x + 6y = -24
5x = 45
5 5
x = 9
x + 3y = -12
9 + 3y = -12
- 9 - 9
3y = -21
3 3
y = -7
(x, y) = (9, -7)
Answer:
the amount paid by the customer for the product is $192.40
Step-by-step explanation:
The computation of the amount paid by the customer for the product is shown below:
= Total amount + Total amount × tax rate
= ($299 + $10 - $99 - $25) + ($299 + $10 - $99 - $25) × 0.04
= $185 + 185 × 0.04
= $185 + $7.4
= $192.40
Hence, the amount paid by the customer for the product is $192.40
We simply applied the above formula so that the correct value could come
And, the same is to be considered
The probability of each is the fraction of that item (or group of items) to the total. They just tried to trick you by listing Science with subcategories of biology and chemistry to see if you would add them twice and get the wrong total. Total rooms is M+S+E=5+10+10=25
S=10/25
B=8/25
M=5/25
E=10/25
C=2/25
For the "or" questions you just add them. P(MorE) = P(M) = P(E).
<span>For S and not C that's just B.
I hope my answer has come to your help. God bless and have a nice day ahead!
