37 there are 15 plates in a kitchen cabinet. the diameter of each plate is either 7 inches or 12 inches. the diameter of all 15 plates combined is 140 inches. which system of equations can be used to find the number of 7-inch plates, x, and the number of 12-inch plates, y, that are in the cabinet? a x + y = 140 12x + 7y = 15 b 7x +12y = 140 7x + 12y = 15 cx + y = 15 7x + 12y = 140 d x + y = 15 12x + 7y = 140

it would be 7x+12y=140

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.

y=sec x is the correct answer
