Y= kx (k being a constant)
10= k × 4 k=5/2
y= 5x/2 The answer is C.
It's zero, additive inverse means they're opposite numbera
Answer:
20 people only buy dvds.
Step-by-step explanation:
There are two groups in this problem. One group of people that buys dvds and one that buys blu rays. The total amount of people who buy blu rays is 300, but there's an intersection between the groups and the size of this is 280 people who actually buy both. In order to find out how many people only buy DVDs we first need to figure out how many only buy blu-rays. That is:
people who only buy blu rays = people who buy blu rays - people who buys blu rays and dvds
people who only buy blu rays = 300 - 280 = 20
We can now calculate the amount of people who only buy dvds and that is:
people who only buy dvds =total amount of people - ( people who only buy blu rays + people who buy both)
people who only buy dvds = 320 - (20 + 280) = 320 - 300 = 20 people
Answer:
Step-by-step explanation:
Let's find the volume of the room in ft³ and that will give
14×22×9=2772ft³
There are deductions. Hence we subtract them from this value
3×5=15, but there are two, hence 15×2=30ft²
And 4×7=28ft²
Hence 2772-(30+28)=2714
Dividing this value by 320 gives
8.4(to 2s.f)
25 minutes!! you were very close, you just needed to translate the fraction to minutes!
