So we know that the three boys are friends – Sam, Ryan and
Daniel.
We also know that Daniel is Ryan’s brother and Ryan is Sam’s
brother.
But the question here is why does Sam is not Daniel’s
brother.
Because the answer here is Sam is a girl which makes her a
sister of Daniel, not a brother.
Answer:
3 and 7,
7 and 11,
13 and 17
Step-by-step explanation:
Prime numbers have exactly two factors, the number itself and 1. This just means that nothing "goes into" these numbers. Example: 7. 7 is a prime number; the only number that goes into 7 is 7 (and 1)
First, find all the prime numbers that are less than 20:
2, 3, 5, 7, 11, 13, 17, 19
Next find the pairs that are 4 units apart. 3 and 7 works.
7 - 3 is 4
Also, 13 and 17 works, and 7 and 11.
Answer:
Width = 44 yards
Length = 171 yards
Step-by-step explanation:
Given:
<em>Perimeter of the rectangular field = 430 yards.</em>
Let:
<em>The length of the field be L</em>
<em>The width of the field be W.</em>
From the question:
<em>The length of the field is 5yards less than quadruple the width. This implies that;</em>
L = 4W - 5
But.
Perimeter (P) of a rectangle is given by:
P = 2(L + W) ---------------(i)
Substitute the values of P = 430, L = 4W - 5 and W into equation (i) as follows;
430 = 2(4W - 5 + W)
430 = 2(5W - 5)
430 = 10W - 10
10W = 430 + 10
10W = 440
Divide both sides by 10
W = 44
Therefore, the width of the field is 44 yards.
Remember that,
L = 4W - 5
[Now substitute W = 44]
L = 4(44) - 5
L = 176 - 5
L = 171
Therefore, the length of the field is 171 yards
