Answer:
211 cm
Step-by-step explanation:
upper rectangle + lower rectangle (11-8=3) + end triangles
(8x20) + (3x12) + (1/2x3x5 each x2)
160+36+15=211
You can see that an odd number of steps is simply multiplying the number of steps by a number that moves up one each time. For instance, 1*1, 3*2, 5*3, etc. It's a bit harder with the even numbers. Their pattern is multiplying half the number of steps by 1.5, but the ones place value moves up a number each time, for example, 2*1.5, 4*2.5, 6*3.5. This means that 10 steps is 10 * 5.5, or 55 blocks and that 100 is 5,050 steps.
90=6x+3x
90=9x
90/9=x
10=x
3x=3*10=30
6x=6*10=60
hope this helped
Based on your distance from the state border and the cruise control speed, the minimum and maximum hours you will have cruise control on is:
- Minimum - 1/3 hours
- Maximum - 1.5 hours
<h3>How long will cruise control be on?</h3>
You are 55 miles from the state border. You want to put the cruise control off within 35 miles of the border on either side.
This means that you might put it off in:
= 55 - 35
= 20 miles
The time to 20 miles is the minimum time the cruise control will be on:
= 20 miles / 60 miles per hour
= 1/3 hours
If you put it off 35 miles after the border, the distance is:
= 55 + 35
= 90 miles
The maximum time is:
= 90 / 60
= 1.5 hours

Answer:
Step-by-step explanation:
The discriminant tells you where the graph of the parabola goes through the x-axis, if at all. If the discriminant is negative there are no real zeros and the parabola does not cross or touch the x-axis; if the discriminant is positive the parabola will go through the x axis in 2 places; if the discriminant is 0 the parabola will touch the x-axis in 1 place. Our discriminant is 0 since the parabola only touches the x-axis but does not go through.
