First we need to find the length. So we do 126/3 to get 42. The length is 42. Now to find perimeter we do 2(42)+2(3) or 42+42+3+3.
Both ways are right ways. The perimeter is 90 meters.
Hope that helps!!
First you need to make both bases the same:
Lets remove the ^p and ^4
To make the base of 42 equal to 41, you would have 41^x = 41
X - ln(42) / ln(41) = 1.00648904
Now you have 41^1.00648904(p) = 41^4
Now the bases are equal so we need to set the exponents to equal:
1.00648904(p) = 4
Divide both sides by 1.00648904 to solve for P
P = 4 / 1.00648904
P = 3.97421114
125 divided by 100 is 1.25, 1.25 times 15 is 18.75.She tips $18.75
Divide total bought by 3 and multiply by 20cents:
210/3 = 70
70 x 0.20 = $14.00
Subtract the amount they paid by the amount they made:
14.00 - 6.50 = $7.50
The profit made was: $7.50
Answer:
longest side=3.6
let ratio 3:5:6:9be 3x,5x,6xand9x
perimeter= sum of all side
9.2=3x+5x+6x+9x
9.2=23x
x=9.2÷23
x=0.4
9x=9×0.4=3.6
6x=6×0.4=2.4
5x=5×0.4=2
3x=3×0.4=1.2
