Answer:b
Step-by-step explanation:
Answer:
Records: $6000
Grass Seed: $4000
Toys: $3000
Food: $11000
Step-by-step explanation:
We have to use the number of degrees in each category in comparison to the total number of degrees in a circle, 360 degrees. Records is 90 degrees, so 90:360 = 1:4 = 1/4. So 1/4 of the total pie is $6000. For food, we add the other sub-category's costs, and subtract that from $24000.
The total temperature of the magnesium sample is its original temperature plus the temperature increase which is dependent on time. This total should exceed 650 degrees. Thus, the inequality that best describes the condition is,
255 + 10m ≥ 650
m ≥ 39.5
The answer is letter b.
Answer:
6 hours and 20 minutes
Step-by-step explanation:
7*50=350 so 350+30=380 then 380/60= 6 hours and 20 minutes
