Ms. Hanley and Ms. Simpson's classes are trying to see which class can raise the most money for their end of year party.
• Ms. Hanley's class has already raised $150 dollars and each student is going to
donate $4 more dollars.
Ms. Simpson's class has already raised $100 dollars and each student is going to
donate $9 more dollars.
Which equation can be used to find t, the number students needed to donate for
each class so that the total amount raised is the same for both classes?
A. 9t + 150 = 4t + 100
B. 4t + 150 = 9t + 100
C. 9 + 150t = 4 + 100t
D. 4 + 150t = 9 + 100t

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

pls ask

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 have no clue what you just said. write a question in english?
