Answer:
Just so you hear, Whirlybot, these circle problems are always "tricks" and they are tough. You have to remember a bunch of implied things
Step-by-step explanation:
One thing to recall is that the angle from the tangent point to O at the center is also a 90° angle. so you now know, that the line from the point where the circle touches the tangent line to the center is a right angle and you have part of that 90° already. the 50 is one part and there for the next part is 40 ° Since we now know that the line from the tangent to the center is forming an internal angle with that line going to X of 40 ° we know that X is also 40 ° b/c the triangle formed by the line to the center is going to be the same length as the line from the center to the X. That's an Isosceles triangle. they have the same angles at the two same length legs.
I know, I went thur a whole pile of logic, but that's what makes this kind of problem tough. you just have to keep thinking about things you know.
X = 40 °
Answer:
85-4x<40
12 cars
Step-by-step explanation:
85-4x<40
Solve for x.
-4x<-45
x<11.25
If he build 11 cars, the amount of tires would be over 40, so if he builds<u> 12 </u>cars, it will be below 40.
5 2/3 gallons of fuel ... 2 hour trip
x gallons of fuel = ? ... 1 hour
If you would like to know how many gallons were used each hour, you can calculate this using the following steps:
5 2/3 * 1 = 2 * x
17/3 = 2 * x /2
x = 17/6 = 2 5/6 gallons of fuel
The correct result would be 2 5/6 gallons of fuel.
Answer: no
Step-by-step explanation:
because you can do what is known as the vertical line test to determine if it is a function you do that by plotting it and if it goes in a vertical line then it is a function
