Answer:
GCF = 2 :)
Step-by-step explanation:
The greatest common factor is the biggest number that each number is divisible by.
There is no number greater than 2 that 14, 4 and 42 are all divisible by! :)
No because 21=(11)+9
21 can’t equal to 20
First you need to find the area of the plate.
The formula for the area of a circle is Area = pi *r^2
The radius (r) is given as 6 inches.
We will use 3.14 for pi
Area = 3.14 x 6^2
Area = 3.14 x 36
Area = 113.04 square inches.
Now to find the density, divide the total bacteria by the area:
Density = 120,000 / 113.04 = 1061.57 which rounds up to 1,062 bacteria/ square inch.
Answer:
Step-by-step explanation:
By Pythagoras' Theorem, a² + b² = c².
Substituting the values of a and b, we get:
7² + 25² = c²
49 + 625 = c²
c² = 674
c ≈ 26.0 (to 1 d.p.)
