Answer:
b . 6 is the length of the hypotenuse
 
        
             
        
        
        
Easy
first term is n=1
so 10th term is n=10
5(10)+100=50+100=150
150 is 10th term
        
             
        
        
        
Answer:
216 cookies
Step-by-step explanation:
From the question,
Let the total cookies in the first place be x cookies.
Their ratio = 5:12:9
Total  = 5+12+9 = 26.
Weiming share = (5/26)x = 5x/26
If weiming sold 28 cookies
⇒ (5x/26)-28
⇒ (5x-728)/28
Hence Weiming new share = (5x-728)/28 cookies
The new ratio is 1:8:6
The total cookies becomes = x-28
Therefore,
(1/15)(x-28) = (5x-728)/28
(x-28)/15 = (5x-728)/28
Crossmultiply
28(x-28) = 15(5x-728)
28x-784 = 75x-10920
Collect like terms
28x-75x = -10920+784
-47x = -10136
x = -10136/-47
x = 215.7
x ≈ 216 cookies
 
        
             
        
        
        
Answer:
280 cm2
Step-by-step explanation:
1)find the area of square 
A=LW
 =10×10
 =100 
2) find the area of triangle
A=B×H÷2
 =10×9/2
 =45
Coz,there are 4 triangle we multiple by 4
 =45×4
 =180
3)find the total surface area by adding the two
 =100+180
 =280cm2
 
        
             
        
        
        
Answer:
Undefined
Step-by-step explanation:
m = Δy / Δx
m = (12 − -8) / (-6 − -6)
m = 20 / 0
m = undefined
The slope is undefined.
