H = height of triangle
b = length of triangle base
A = area of triangle
Recall the formula for area of a triangle :
A = 1/2 bh
Plug in what was given in the problem :
h = b - 5
A = 42
A = 1/2 bh
42 = 1/2 b (b-5)
They will usually have a dash in the line, or the same number next to both of them.
Hope this helped!
Answer: x = 27°
Step-by-step explanation: Both are alternate interior angles
The multiplicative inverse of 1000/450 is 9/20
<h3>How to determine the inverse of the number?</h3>
The multiplicative inverse of a number x is:
Inverse = 1/x
The number is given as: 1000/450.
So, we have:
Inverse = 1/(1000/450)
Evaluate the expression
Inverse = 450/1000
Simplify
Inverse = 9/20
Hence, the multiplicative inverse of 1000/450 is 9/20

Step-by-step explanation:
The formula for distance traveled (in this case the distance a submarine descends) over a period of time is:
d=rt
where
d is the distance traveled (or descended),
r is the rate of travel and
t is the time.
In this problem we are told the rate,r is 96.4 feet per minute. And, we are told the time, t
to calculate for which is 5 minutes.
Substituting these into the formula and calculating gives:
d=90feetmin
t=5min
d=96.4feetx5
d=482feet
