Answer:
X+190=7602
X=7412
Step-by-step explanation:
The odometer read 7412 miles at the beginning of the trip.
A = (1/2)bh [b = 10 m, h = 6 m]
A = (1/2) * 10 * 6 = 30 m²
Answer: 300*0.73^x
Step-by-step explanation:
300 is the initial value and every time x goes up by 1, the value get multiplied by 0.73
when x=3
then the value would be 300*0.73*0.73*0.73 or 300*0.73^3
then for x amount of times the equation would be 300*(0.73 x times ) or 300*0.73^x
There is 3 variable, in this case, painters, walls and time(minutes). You need to find how many painters needed and provided information on the walls and time(minutes).
Increasing walls will cause more painter needed. It was reversed in time which was increased time will cause less painter needed.
In this case, you need to divide the variable walls with time since it reversed so: 27wall/9 minutes
It equal to : 3 walls/minute
Information provided is:
3 painters= 3 walls/3 minutes
Equal to : 3 paintes= 1 wall/minute
To make it 3 walls/minute, the painter needed will be:
(3 walls/minute) / (1 wall/minute) x 3 painters= 9 painters
Answer: 9 painters
