Answer:
22.5 miles per hour
Step-by-step explanation:
<u>Given system of equations</u>
5(s-w)=900
4(s+w)=900
<u />
<u>Set equations equal to each other</u>
5(s-w)=4(s+w)
5s-5w=4s+4w
s-5w=4w
s=9w
<u>Solve for w using the substitution s=9w</u>
4(s+w)=900
4(9w+w)=900
4(10w)=900
40w=900
w=22.5
Therefore, the speed of the wind is 22.5 miles per hour
Answer:
Step-by-step explanation: when you first open the graphing tool you have to click relationship and choose custom. put in gwen’s equations (y=100+10x) then go to relationship and choose custom again and put in tristan’s equation (y=12.5)
also click on the settings button at the bottom of the graph and put the x axis to -100 min and 100 max and for y axis put -1000 min and 1000 max or you could choose your own numbers but thats just what i put
Basically, this problem is going to require you to solve for the area and multiply it with the given cost unit.
Area = Length*Height
Area = 100 ft * 8 ft = 800 ft²
Total Cost = (Unit Cost)(Area)
Total Cost = ($2/ft²)(800 ft²)
<em>Total Cost = $1,600</em>
Answer:
= 30 km
Step-by-step explanation:
12.5 * 240/100
<em><u>= 30 km</u></em>
The value of the probability is 0.54
<h3>How to determine the probability?</h3>
The given parameters are:
P(A) = 0.35
P(B) = 0.54
From the question, we understand that the events are independent.
This means that
P(B|A) = P(B)
Substitute P(B) = 0.54
P(B|A) = 0.54
Hence, the value of the probability is 0.54
