Answer: -3.3°F

Step-by-step explanation:

In integers , we represent fall in quantity by negative numbers.

Since, the temperature at noon was 16.8°F . By dropping it by  20.1°F means there is a - 20.1°F  change in the temperature.

Then, the temperature at midnight = 16.8°F + (- 20.1°F)

=  16.8°F - 20.1°F

= -3.3°F

Hence, The temperature at midnight was -3.3°F .

Solve eight and two fourths minus three and one third
soldier1979 [14.2K]

Answer:

5 1/6

Step-by-step explanation:

Rewriting our equation with parts separated

=8+2/4−3−1/3

Solving the whole number parts

8−3=5

Solving the fraction parts

2/4−1/3=?

Find the LCD of 2/4 and 1/3 and rewrite to solve with the equivalent fractions.

LCD = 12

6/12−4/12=2/12

Reducing the fraction part, 2/12,

2/12=1/6

Combining the whole and fraction parts

5+1/6=5 1/6

Jalen made $533.75 while working at his job. He makes $15.25 an hour, how many hours did he work to make that amount of money?
mixer [17]

Answer:

35 hours

Step-by-step explanation:

Typically, people get their paycheck after 2 weeks.

Let say he worked 8 hours a day, a typical amount of hours for the average human who has a occupation.

Multiply the amount of hours by the amount payed every hour.

So 15.25 x 8 is 122

( so in 8 hours jalen made $122)

Add 8 hours, which would now be 16 hours worked.

16 x 15.25 = 244

(so in 16 hours jalen made $244)

Add another 8 hours of work time which would now be 24 hours (1 full day)

24x5.25=366

Add 10 hours on now which would be 34 hours worked (2 days = 48 hours meaning she worked 1 day and 10 hours )

34x15.25=518.50

(getting closer to the amount she earned)

So if we add another hour

which would be 35 hours worked (1 day 11 hours)

35 x 15.25 = 533.75

Therefore, Jalen worked 35 hours.
