Answer:
r = 2.5
Step-by-step explanation:
4 X 2.5 = 10
5 x 2.5 = 12.5
10 x 2.5 = 25
Answer:
The area of a rectangle is 520 square inches. The length is 3 more than twice the width. The equation 520 = 2w2 + 3w can be used to find the length and width of the rectangle.
Step-by-step explanation:
1st statement:
l= 2w+3
A= l × w
520= w×(2w+3)
520= 2w²+ 3w
2nd statement:
length of fencing= w+2l
120= w+2l
l= 60-w/2
A= (60-w/2) × w
A= 60w- w²/2
Hence this statement is incorrect
3rd statement:
H= x
B= x-4
P= x-2
Accoriding to pythagoras theorem
H²=P²+B²
x²=(x-4)²+(x-2)²
x²= x²-8x+16 + x²-4x+4
0= x²-12x+20
Hence this statement is incorrect
4th statement:
two consecutive even numbers are given by n and n+2
So this statement is incorrect
the number of athletes who do not play basketball is 26.
Step-by-step explanation:
<u>DATA:</u>
Athletes surveyed = 107 athletes
<u>Athletes who play basketball</u>
Athletes who play baseball = 48 athletes
Athletes who don't play baseball = 33 athletes
Athletes who play basketball = athletes who play baseball + athletes who don't play baseball
Athletes who play basketball = 48 + 33
Athletes who play basketball = 81
<u>EQUATION:</u>
Total athletes = Athletes who play basketball + Athletes who don't play basketball
107 = 81 + x
x = 107 - 81
x = 26
Therefore, the number of athletes who do not play basketball is 26.
