Answer:
I think it's 105.
Step-by-step explanation:
The wording is sort of unclear, but I drew it out and it seems that they are alternate interior angles. Alternate interior angles are congruent! If this is not the right answer, please tell me and I might be able to tell another one.
Well, technically, it has to be either 75 or 105, because all of the special relationships of triangles are either that they are supplementary or they are congruent. So if it's not 105, try 75 :)
Answer: b
Step-by-step explanation:
10 x 10= 100
15 x 10= 150
100+150= 250
K = Kevin's age
D = Daniel's age
K = 3D
K - 4 = 5(D - 4)
Plug in 3D for the K values in the second equation.
3D - 4 = 5(D - 4) Use the Distributive Property
3D - 4 = 5D - 20 Add 4 to both sides
3D = 5D - 16 Subtract 5D from both sides
-2D = -16 Divide both sides by -2
D = 8
Now, plug that D value into the original equation.
K = 3D Plug in the D value
K = 3(8) Multiply
K = 24
Finally, you can double check your math.
4 years ago, Daniel would've been 4 and Kevin would be 20, so Kevin would've been 5 times as old as Daniel. And 8 x 3 = 24.
So, Kevin is 24.
An area of rectangle: a · b
a = 0.4 km
b = 0.07 km
a · b = 0.4 km · 0.07 km = 0.028 km²
Answer:
See below.
Step-by-step explanation:
"Part A:
(1,5.5)
(2,5)
(3,4.5)
(4,4)
(5,3.5)
(6,3)
Every hour (x value) I subtracted 0.5 from the candle height (y value) since it burns at 0.5 inches per hour.
Part B:
Yes, this is a function because there is a constant relationship between the input and the output.
Part C:
Yes, this will continue to be a function because there is still a constant relationship, even though its different than the first one.
(1,5.7)
(2,5.4)
(3,5.1) ect."
