280divided by 8= 35 . Answer: they sold 35 burgers per hour ! hope this helped !
The answer would be C:
It is a radical equation because you are solving for the variable under the radical.
To think of it another way, you must deal with the radical to find the answer
Start by multiplying the amount of passengers by 2 (for amount of meals)
524×2= 1,048
That will equal to 1,048, which is the amount of meals given out for a full plane in one day.
Now multiply that by 7 (for one week) and you'll get your answer!
524×2= 1, 028 × 7 = 7, 336 meals
7, 336 meals are given out in a one week time span on a fully packed plane.
Answer:
128 and 204
Step-by-step explanation <em>(note, it is not the shortest way)</em>:
- if the initial value of the 1st number is 'x' and of the 2d number is 'y', then after decreasing their values is 0.8x and 0.85y. The phrase 'then the sum would be 68 less' means the sum after decreasing is 400-68=332.
- Using this it is possible to make up the system of two equations then resolve it:
- before decreasing x=160 and y=240. After decreasing x=160*0.8=128 and y=0.85*240=204.
Answer: it will take 10 minutes to get back to room temperature.
Step-by-step explanation:
Let us assume that the room temperature is 25 degrees. The current temperature of the soup before the decrease would be 25 + 50 = 75 degrees.
The soup drop about 5 degrees every minute. This is a linear rate. The rate at which the temperature is decreasing is in arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = 75 degrees
d = - 5 degrees (it is decreasing)
n = t
We want to determine how long it will take to get back to 25 degrees, . Therefore,
25 = 75 -5 (t - 1) = 75 - 5t
5t = 75 - 25 = 50
t = 50/5 = 10 minutes
