Answer:
the answer 200.
Step-by-step explanation:
50 X 1= 50
50 X 2= 100
50 X 3= 150
50 X 4= 200
or
50
x 4
First, 0 X 4= 0
Then you do the 5 X 4= 20
So now you have 200
Hope I helped :)
Answer:
- 278.4°F
Step-by-step explanation:
Temperature of Object ( T ) = 1200° F
Temperature of surrounding ( M ) = 80°F
Time ( t ) = 1 hour
dT / dt ∝ ( M - T )
dT /dt ∝ | ( 80 - 1200 ) |
dT / dt = k ( 1120 )
(1200 - 830 ) / 1 = k ( 1120 )
hence k = ( 1200 - 830 ) / 1120
= 370 / 1120 = 0.33
<u>what is the object's temperature (x )after 4 hours </u>
( 1200 - x ) / 4 = 0.33 ( 1120 )
( 1200 - x ) / 4 = 369.6
hence x = 1200 - ( 4 * 369.6 )
= - 278.4 ° F
X is cheeseburgers and y is hamburgers
x + y= 351
2x+y=351
Now I can do 351 divided by 3 which gives me 117. Since 117+117+117 is 351 and the number of cheeseburgers sold was twice the amount as hamburgers. I will say that there was 117+117 cheeseburgers sold and there were 117 hamburgers sold.
Hope it makes sense.....
B none of them are repeating
Five per person and there will be four extra
