Answer:
Table D. shows the proportional relationship.
You would plot those points on their corresponding part on the graph, like (2,1), (6,3), (8,4), and (10,5). The first number being the x value and the second number being the y value. Remember, x goes from side to side, and y goes up and down.
I think it is a because it says the temperature is less than -5 degrees Fahrenheit
so you know the sign will have to be t<-5 degrees Fahrenheit now you are left with is t a positive or negative number a positive number would automatically be greater than -5 degrees Fahrenheit so there is no way it can be a positive number thus leaving you with one option.
Answer: a
Answer:
9
Step-by-step explanation:
since they're similair then similair sides will be proportional
CB is similair to EF
=
same thing if you try with the hypotenuse AB similair to DE
=
So, if you multiply r (DF) by 3/4 you will get the similair side AC
rx 3/4=12
r= 12÷ 3/4
r=16
We have to use the law of cosines to solve for the missing angle.
cos(?) = (400^2 + 450^2 - 90^2) / (2*400*450).
Since, we want the exact value, we are going to take the inverse cosine of both sides
? = 10 degrees
