The answer is J
The rides she wants to ride cost 4+6+3 tickets so that goes on one side. She already has 7 tickets so you need to know 7 plus what will get her on those rides so those go on the other side. So you have:
7+t=4+6+3
Then you solve for t
7+t=13
t=13-7=6
Hope that helps.
Answer:
You only have to sort (numbers with numbers and variables with variables) then do the operations (+/-).
Step-by-step explanation:
Using it's concept, it is found that there is a 0.45 = 45% experimental probability of the coin landing on tails.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
For an experimental probability, these number of outcomes are taken from previous trials.
In this problem, 9 out of 20 trials resulted in tails, hence the experimental probability is given by:
p = 9/20 = 0.45 = 45%.

Answer:
-90 , 30
Step-by-step explanation:
sina = cos(2a)
= 1 - 2(sina)^2
2(sina)^2 + sina -- 1 = 0
( sina + 1 )( 2sina - 1 ) = 0
sina = -1 or sina = 1/2
=> a = -90 degrees or => a = 30 degrees
Answer: h=3v/pir^2 +1
Step-by-step explanation:
sorry i can't use the pi symbol so i'll be referring to pi as pi
^2 is squared
1/3pir^2(h-1) =v
<u>simplify 1/3pir^2</u>
pi/3r^2(h-1)=v
<u>multiply both sides by 3 and simplify </u>
3*pi/3r^2(h-1)=3v <-- simplify = pir^2(h-1)=3v
<u>divide both sides by pir^2</u>
pir^2(h-1)/ pir^2 = 3v/ pir^2
<u>simplify </u>
h-1 = 3v/pir^2
<u>add 1 to both sides</u>
h-1 +1 = 3v/pir^2+1
answer/ simplify:
h=3v/pir^2 +1
