No wonder you have posted this. It is not easy. Scale is a straight line measurement. You need to use a side of a square.
Left: 1 side of a square = 1 meter.
Center: 3 tops of a square = 1 meter.
Therefore 1 side of a square = 1/3 of a meter.
Right: 1 side of a square = 0.5 meters.
The length of the bacteria should be written in scientific notation.
0.00365 in scientific notation = 3 × 10^-3
Given.
length of the bacteria in decimal = 0.00365 cm long
Scientific notation is written in the format x × 10ⁿ
where,
x = any number between digit 1 and 10
n = exponent (positive or negative).
- To have a negative exponent value, move decimal to the right
- To have a positive exponent value, move the decimal point to the left.
In this case, the nearest significant value is 3
So move the decimal point three times to where 3 is
That is,
0.00365 = 3.65
Since the decimal point is moved to the right 3 times, n = - 3
we have 10^-3
Therefore,
0.00365 in scientific notation = 3 × 10^-3

Discounted by 25% means he paid 75% of the original price:
80 x 0.75 = $60
Now multiply the sale price by 1 + tax rate:
60 x 1.05 = 63
He paid $63 total.
32,410/5=6482
6482*28=181496
181496/63360=2.86miles
Answer:
See below ~
Step-by-step explanation:
Let the bases be x and x + 6.
Substituting the known values into the formula :
- A = 1/2 x (a + b) x h
- 48 = 1/2 x (x + x + 6) x 4
- 2x + 6 = 24
- 2x = 18
- x = 9
The base lengths are :
- x = 9 inches
- x + 6 = 9 + 6 = 15 inches
