Answer:
yES 2:3 
Step-by-step explanation:
The sides are the same length
 
        
                    
             
        
        
        
We know that
circumference=2*pi*r
for r=65/2----> r=32.5 cm
circumference=2*pi*32.5-----> 204.1 cm
so
one revolution <span>of Emma’s bicycle</span> is equal to 204.1 cm-----> 2.041 m
3.2 km-------> 3200 m
1 revolution---------> 2.041 m
x rev------------> 3200 m
x=3200/2.041 ----> x=1567.86 revolutions
the answer is
1567 complete revolutions
        
             
        
        
        
The answer of  is √ 2
 is √ 2
<u>Step-by-step explanation:</u>
The value of   =  √2/ 2
 =  √2/ 2
The value of  = √2/ 2
 = √2/ 2
=   √2/ 2 +  √2/ 2
=  √2 +  √2 / 2
= 2 √2 / 2
Dividing √2 by 1
= √2
 
        
             
        
        
        
Answer:
20 dimes and 2  quarters
Step-by-step explanation:
 x = number of dimes
 y  = number of quarters
minimum is greater than or equal to ≥
x+y ≥16
no more than is less than or equal to ≤ ,
value of dime is $ 0.10
value of quarter is $0.25 so
0.10x + 0.25y ≤ 3.00
Rewrite inequalities in terms of y:
y ≥16 - x
(0.25/0.25)y ≤ (3.00/0.25)-(0.10/0.25)x→
y≤12 - 0.4x
