16 right 4 down
Step-by-step explanation:
Answer:
y = ¼(x-4)
Step-by-step explanation:
Before solving the question, let's look at one example,
- A is directly proportional to B means A∝B which also means A=kB where k is a constant.
In this case, y is directly proportional to (x-4) means that y∝(x-4) which can also mean that y=k(x-4).
Hence, to find the value of k, substitute x=16, y=3 into y=k(x-4),
3=k(16-4)
k=3/12
k=1/4
After that, substitute the k value into the equation,
<h3>y = ¼(x-4)</h3>
Answer:
Neal thinks that he can sell the tickets for $135.
Step-by-step explanation:
Original price at which Neal bought the tickets = $90
If he expects to sell them at 150% of the original,
150% as a decimal = 150/100 = 1.5
the new resale price = 1.5* $90
= $135
Therefore, Neal thinks that he can sell the tickets for $135.
d =st
distance = speed * time
10 = 4.5 * t
divide each side by 4.5
10/4.5 = t
100/45 = t (can't have a decimal in a fraction so I multiply by 10/10)
divide top and bottom by 5
20/9
2 and 2/9 hours
to get minutes multiply 2/9 by 60
2/9 * 60
120/9
13 3/9
13 1/3 minutes
2 hours 13 1/3 minutes
to the nearest minutes
2 hours 13 minutes
1) Sample space of the spinner={Green, Blue, Purple, Yellow, Red}=5
2) Sample space of the cards={Red, Yellow, Blue, Pink }=4
1) P(spinner stops at purple) = 1/5
2) P(pink card selected) = 1/4
1) AND 2) are conditional probabilities:
P(spinner stops at purple ∩ pink card selected ) = (1/5)(1/4) = 1/20 =0.05
