Speed was increased 20% to 48 mph. What was the speed before the increase

Mathematics
1 answer:
grigory [225]3 years ago
8 0

Answer:

40 mph

Step-by-step explanation:

If the speed increased by 20%, now the speed is 120% of the original speed.

48 mph is 120%, so dividing by 6 will get 8 which is 20%.

If 8 is 20%, you can multiply it by 5 to get 40, which is 100%. This means 40 mph is the original speed.

Hope this helps!

The sum of two trinomials is 7x2 - 5x + 4. if one of the trinomials is 3x2 + 2x - 1, then what is the other trinomial?
Margarita [4]

Answer:

  b.  4x^2 -7x +5

Step-by-step explanation:

When you know a sum and one of its contributors, you can find the other by subtraction. The other trinomial is ...

  (7x^2 -5x +4) - (3x^2 +2x -1)

  = (7 -3)x^2 +(-5 -2)x +(4 -(-1))

  = 4x^2 -7x +5 . . . . . matches B

aleksandrvk [35]

9514 1404 393

Answer:

  D. the midline is 2

Step-by-step explanation:

The maximum is the largest value of the function: 5. (not 2)

The minimum is the smallest value of the function: -1. (not -2)

The amplitude is half the difference of the minimum and maximum: (5-(-1))/2 = 3. (not 2)

The midline is the average of the minimum and maximum: (5-1)/2 = 2.
