Answer:
y = (10 * 0.2) ^ x
Y = (2)^x
Y = 2^x + 10
6.5 hours
Step-by-step explanation:
Y is the number of people at the school who have been infected with the flu. The 10 is the initial number of infected students which is a constant so it does not change. The 0.2 is the rate of increase, or 20%. The x exponent is the number of hours so that is a changing number. Your answer is 2 to the power of the number of hours which is x. Add ten after that to get your number. to get 100 people ill, it would take about 6.5 hours.
Answer:
A. 1/8, 4/32
Step-by-step explanation:
We have four pairs of ratios and are asked to find which pair equals the same amount.
To do so, we just need to see what ratio can multiply into both numbers equally into the first pair and forms the second pair.

Answer:
volume left in A is 80ml
Step-by-step explanation:
let original volume in both be x ml
after pouring from A to B
vol in A = x - 120
vol in B = x + 120
now it is given that
vol in B = 4 times vol in A
implies
hence original volume in A is 200ml. after pouring in B it is 200-120 = 80 ml
Answer:
I think she is going to take 1 green cube out from “the other bag”... I’m only in 5th grade....
Step-by-step explanation:
1. One Bag = 4 + 1 = 5
2. Other Bag = 3 + 3 = 6
If she takes out 1 from the other bag, they will both contain 5.
6 - 1 = 5
Step-by-step explanation:
we know that,
- area of rectangle = length × breadth
Now,
rectangle PQRS has it's
breadth = 3
length = 4+b
Then,
area of rectangle PQRS = (4+b) × 3
= 12 + 3b
Hence,
The area of rectangle is 12+3b.
