Answer:
a) 20
Step-by-step explanation:
Use similar triangles.
2/3 = x/30
3x = 2 * 30
3x = 60
x = 20
Answer: a) 20
Answer:
The first thing we must do for this case is to define variables.
We have then:
x: number of slices
y: total cost
We write the linear function that relates the variables.
We have then:
Then, we evaluate the number of slices to find the total cost.
-two slices cost:
We substitute x = 2 in the given equation:
Answer:
two slices = 2.2 $
-ten slices cost:
We substitute x = 10 in the given equation:
Answer:
ten slices = 11 $
-half a slice cost:
We substitute x = 1/2 in the given equation:
Answer:
half a slice = 0.55 $
Answer:
The number between 1 and 10 is 3
The power of 10 is 4
The number in scientific notation is
-3.46 × 10^4
