A. 1.395
2.31 - 0.915 = 1.395
Answer:
Last option, a translation of 1.5 units left, 0.5 unit up, then a reflection across the x-axis
Step-by-step explanation:
Let's pick any random point. So let's just chose point L. Comparing point L to point L', we can already see that the options given are incorrect. For example, the first option with just translations is incorrect because when we do translate point L 1.5 units left and then 1.5 units down, it does not line up with point L'. For the second and third options, we know that L(-2.5, 1.5) and L'(-4,-2). Therefore, there must be some sort of shift left, right, up, or down, to go from coordinates with decimals to coordinates with whole numbers, leaving the last option, D, as the correct one.
The answers are 9.8 and 10/3
Answer:
3x+3=-36 is the equation
The answer is -13,-12,-11
Step-by-step explanation:
So consecutive integers, so lets say it’s x, if it’s consective it means the next number after, (Ex: 1,2,3,4,5) so the pattern is x+x+1+x+2 and so on. In this a
cade it’s 3 numbers so x+x+1+x+2 which is 3x+3.
Were trying to find -36 so 3x+3=-36
Solve the equation and you’ll get -13.
Add 1 to -13 and add 2 to -13 and you have your 3 consecutive numbers!
-13+1=-12 -13+2=-11. The original is -13
check: -13+-12+-11=-36 is correct
The equation is
3x+3=-36
We know that
[surface area of sphere]=4πr²
[surface area of hemisphere]=2πr²
(sphere)
r=12 in
[surface area of sphere ]=4π12²--------> 576π in²
(hemisphere)
r=12 in[surface area of hemisphere ]=2π12²--------> 288π in²
[the ratio of the surface area of sphere to the surface area of hemisphere]
=576π/288π-------> 2
the answer is
the ratio is 2
