Answer: 42 = 2*3*7</h3>
Explanation:
Here is list of the first few primes = {2, 3, 5, 7, 11}
Divide 42 over the smallest prime 2 and we get
42/2 = 21
This shows that 2 is a factor (since we get a whole number result).
We don't have another factor of 2 because 21/2 = 10.5 isn't a whole number. But 3 is a factor because 21/3 = 7
Ultimately the numbers 2, 3 and 7 are factors of 42. They are the only prime factors and there's only one copy of each.
42 = 2*3*7
Check out the diagram below. It shows two different ways to generate a factor tree for the number 42.
Answer:
20
Step-by-step explanation:
Given that: $3.25 in dimes and nickels were distributed among 45 boys.
1 nickel = $0.05
1 dime = $0.10
Let number of coins of dimes be x and the number of coins of nickel be 45-x.
Hence,
0.10x + 0.05(45-x)=3.25
0.10x+2.25-0.05x=3.25
0.05x=3.25-2.25
0.05x=1
x= 1/0.05
x=20
45-x
45-20=25
In the coordinate plane, the length of the line segment that connects points at (0, -1) and (-7, -2) is 7.07 units.
<u>Step-by-step explanation:</u>
Here we have ,in coordinate plane we are given two points (0,-1 ) & ( -7,-2 ).
From Straight line concept, we know that Distance between any two pints in a plane i.e distance between points and is given by:
, Here = and =
Putting values in above formula we get:
⇒
⇒
⇒
=
∴In the coordinate plane, the length of the line segment that connects points at 0, -1 and. -7, -2 is .
