It’s (x-6)(x+4) so the first one and last one
Hi, here is the solution...
Part B)
The Navy Pier Ferris has the circumference is 56% of the circumference of the first Ferris wheel.
The Navy Pier Ferris Circumference = 439.6 feet
Let's assume "x" be circumference of first Ferris wheel.
56% of x = 439.6
0.56 x = 439. 6 [56% = 0.56]
x = 439.6/0.56
x = 785.
Therefore, the circumference of the first Ferris wheel is 785.
It is diameter = 785/3.14 = 250 feet
So it is radius = 250/2 = 125 feet.
Part C)
The circumference = 785 feet
Speed = Distance/Time
Speed = 785/9
Speed = 87.2 feet per minute.
That's it. Hope you will understand the steps.
Thank you. :)
I think you are to add then divide by 3 hope I helped a little
Step-by-step explanation:
Since B is the midpoint of AC. So,
AB = BC
12x - 12 = 4x + 28
12x - 4x = 28 + 12
8x = 40
x = 40/8
x = 5
Now,
AB = BC = 4(5) + 28
= 20 + 28
= 48 cm
Now
AC = AB + BC
AC = 48 + 48
AC = 96 cm
Answer: 18.96 km/h
Step-by-step explanation:
Gwen:
65 miles = 104.6 km
104.6 km / 2.5 h = 41.84 km/h
Bryn:
15 min = 0.25 h
76 km / 1.25 h = 60.8 km/h
Difference:
60.8 - 41.84 = 18.96 km/h
Hope this helps!
