Which system represents the problem? Click on the correct answer.
The staff at Aretha's Furniture built 60
chairs and stools in one day. It takes one
person 3 hours to produce a chair and
Zhours to build a stool. How many of
each were made if the staff of 12 people
worked 8 hours each?
x + y = 60; 2x + 3y = 12
x + y = 96; 2x + 3y = 60
You can use a system of equations to find
the answer. Let x = the number of chairs,
and y = the number of stools.
x + y = 60; 3x + 2y = 12
x + y = 60; 3x + 2y = 96
someone help me please

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to

pls mark as brainliest

cant open file sorry!

step-by-step explanation:

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.
