You and god bless

in an isosceles triangle, a leg is 3 more than 1/3 of the base. if the perimeter is 31, find the length of each side.

Step-by-step explanation:

let the base=3x

other sides=(1/3)(3x)+3=x+3

perimeter=3x+2(x+3)=3x+2x+6=5x+6

5x+6=31

5x=31-6=25

x=25/5=5

x+3=5+3=8

3x=3*5=15

sides are 8,8,15

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

i'm not really sure how to answer that
