A concession stand at a basketball game sells hamburgers and soda. Each hamburger costs $2.99 and each soda costs $1.99. At the end of the evening, the concession
stand made a total of $447. There was total of 187 hamburgers and sodas
combined sold. Which system of equations can be used to determine how many
hot dogs were sold and how many hamburgers were sold?

step-by-step explanation:

no of data

divide by no of mode

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

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.
