Answer:
a) scale factor = 1.5
b) d length is 7.5
c) Area scale factor is 2.25
Step-by-step explanation:
Given QR =6
And ST =9
Length Scalar factor = enlarged length /previous length
=9/6
=1.5
Length Scalar factor =1.5
b)we know PS enlarged length of PQ
Length scale factor = PS/PQ
1.5 =PS/5
PS =5×1.5
PS =d =7.5
d length is 7.5
c)Formula :
Area scale factor = (length scale factor)2
=(1.5)2
=2.25
Area scale factor is 2.25
This is a horizontal line passing through the point (0,-1).
Slope = zero.
Hope you can read that okay
#831 is one out of the 535 left
1/535
= 0.002
= 0.2%
The probability is 0.2%, which is very low. It's even less than 1%. This means it's still very unlikely to get #831 and more like to get one of the other 534 numbers.
0.2% compared to 99.8%
If you look at these 2 numbers on a number line, you can see 99.8% (the other numbers) is more closer to 100%. This proves Augustin is more likely to chose one of the other numbers and doesn't have to be nervous.
Answer:
1
Step-by-step explanation:
The lateral area of a cylinder is ...
LA = 2πrh
The total area is that added to the areas of the two circular bases:
A = 2πr² +2πrh
We want the ratio of these to be 1/2:
LA/A = (2πrh)/(2πr² +2πrh) = h/(r+h) = 1/2 . . . . cancel factors of 2πr
Multiplying by 2(r+h) gives ...
2h = r+h
h = r . . . . . subtract h
So, the desired ratio is ...
h/r = h/h = 1
The ratio between height and radius is 1.
