Answer:
assuming that the starting temperature is 0 degrees F, the answer would be -12 degrees F
Step-by-step explanation:
Simply multiply 2 by 6 to get 12, and since the temp is dropping that means its below freezing and you have to put a negative sign in front of it.
Answer:
m∠A=42
Step-by-step explanation:
Since they are complementary they must add up to 90°.
(2x+30)+(6x+12)=90
We can just remove parenthesis since you can't really do anything with them.
2x+30+6x+12=90
Combine like terms.
8x<u>+42</u>=90
Do inverse to find the value of x.
<u>8x</u>=48
x=6
Now since we are looking for the m∠A and not x we need to replace the x with the value of x in the ∠A equation.
(<u>2(6)</u>+30)
(<u>12+30</u>)
m∠A=42
Step-by-step explanation: If events are dependent, this means that the outcome of the first event will affect the outcome of the second event.
Let's look at an example.
Gianna has 8 blue socks and 4 red socks in her sock drawer. She chooses one sock at random and puts its on. She then chooses another sock without looking. Find the probability of the following event.
P (red, then red)
These would be dependent events because if she puts a sock on and doesn't replace it, there is 1 fewer sock in the drawer which affects the probability.
