Answer:
The total area:
12 units²
Step-by-step explanation:
There are three parts on this shape:
1 big right triangle
1 rectangle
1 small right triangle
area = (4*4)/2 = 16/2 = 8units²
area = 2*1 = 2units²
area = (2*2)/2 = 2units²
8+2+2 = 12 units²
For this case we have an equation of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: growth rate
t: time
We then have the following equation:
y = 57 (1.31) ^ t
The initial number of bacteria is 57 and the growth rate is 31% per hour.
Answer:
B. The initial number of bacteria is 57 and the growth rate is 31% per hour
I believe it is A
Because his initial starting point is 12 and then 1.5x to increase and reach his goal of 26

We know that soda + hot dog =201
soda is 2x
hot dog is x
2x+x=201
3x=201
divide each side by 3
x=67
2x=134
They sold 134 sodas and 67 hotdogs
