Answer:
Yes
Step-by-step explanation:
3 and 5 don't got a GCF
Answer:
18.85 mm.
7.73 mm^2.
Step-by-step explanation:
The side of the square = sqrt 36 = 6 mm.
Now this side = the diameter of the circle.
So the circumference of the circle = π * 6 = 18.85 mm.
The answer to the second part
= area of the square - area of the circle
= 36 - π *3^2
= 36 - 28.27
= 7.73 mm^2.
54 and 72 Goes in the "Divisible by 6 and 9" column
90 goes in the "Divisible by 5 and 9" column
84 and 96 goes in the "Divisible by 2 and 6" column
hope this helps!
Answer:
35
Step-by-step explanation:
We know the factors of Lena's age are 2 and 5. The least common multiple must have these factors and the factors of 14, so will at least have factors of 2, 5, and 7.
Apparently, the dad's age is 5·7 = 35.
___
The GCF is 5; the LCM is 70 = 5×14.
_____
Sometimes, I use a little 3-part diagram to think about LCM and GCF. Here, it would look like ...
(2 [5) 7]
where the numbers in curved brackets (2·5) and the numbers in square brackets [5·7] are factors of the two numbers of concern (Lena's age, her dad's age). The middle number in both brackets [5) is the greatest common factor, and the product of all three numbers is their least common multiple.
Here, the product of outside numbers, 2·7 = 14, represents the ratio of the LCM to the GCF. We know that Lena's age has factors of only 2 and 5, so the numbers in the diagram have to be (2[5)7], where 2 and 7 are on the ends and 5 is in the middle.
