Answer:
4(n+7)=
Step-by-step explanation:
4 times the sum of the equation n plus seven
The answer is A $ 167
I=pr^t-p
I=500(104.2/100)^7-500
I=500(1.042^7-1)
I=$167.00 to nearest dollar
Answer:
16
Step-by-step explanation:
Median means the middle number. So you can look at it like this:
<em>a,b,</em> 20, <em>c,d</em>
Those are the variables for the numbers we do not know. We do know that they are all even numbers and they are consecutive, meaning in sequence. So if they are all even, then there should be a gap of 2 between each. They should also be in order. Knowing that, you can subtract 2 from 20 to get b, subtract 2 from b to get a, add 2 to 20 to get c, and add 2 to c to get d.
This should be your answer:
16, 18, 20, 22, 24
Consecutive, and even.
X = velocity of plane
y = velocity of wind
x - y = 1680/5 = 336 mph .....(1) [ plane flying against the wind]
&
x + y = 1680/4 = 420 mph....(2) [ plane flying with the wind]
Adding (1) and (2) to eliminate y gives
2x = 756
x = 378 mph is the speed of the plane with no wind.
