230 per hour. multiply 230 by the number of hours to find total posters.

The equation is Total = 230 x hours written as T = 230x, where x is the number of hours.

you have the total, so replace t with the value and solve for x:

1265 = 230x

Divide both sides by 230:

x = 1265 / 230

x = 5.5 hours.

Mean is the average. To find the average, add the four scores together and divide by 4.

The expression is Mean = ( score 1 + score 2 + score 3 + score 4)/4

Replace what is known:

20 = (25 + 15 + 18 + p)/4

Simpligy:

20 = (58 +p) /4

Multiply both sides by 4:

80 = 58 + p

Subtract 58 from both sides:

p = 80 - 58

p = 22

-10 F is colder than -4 degrees?
Aleks04 [339]

Answer: yes, it is a smaller temperature, which means that is "colder"

Step-by-step explanation:

I guess that the question is:

Is -10°F colder than - 4°C?

Ok, when we have a temperature T in Celcius, the equation to transform this quantity to the Fahrenheit scale is:

T' = (T*9/5) + 32°

Replacing T by the temperature in celcius, we get:

T' = (-4°*9/5) + 32° = 24.8°F

This means that -4°C is equivalent to 24.8°F

And -10°F is a smaller value than 24.8°F (which mean that is colder)

This implies that -10°F is colder than -4°C

Then the statement is true.
