<h2>
Average rate of lowering per minute = 36.67 ft/min</h2>
Step-by-step explanation:
After 10 minutes, the bell is at a depth of 600 ft
After 10 minutes
Depth of bell = 600 ft
After 40 minutes the bell is at a depth of 1,700 ft.
After 40 minutes
Depth of bell = 1700 ft
Time gap = 40 - 10 = 30 minutes
Depth fallen = 1700 - 600 = 1100 ft
We have
Depth fallen = Average rate of lowering per minute x Time gap
1100 = Average rate of lowering per minute x 30
Average rate of lowering per minute = 36.67 ft/min
Answer:
180 hamburgers
120 hotdogs
Step-by-step explanation:
In this question, we are asked to calculate the number of hamburgers and hotdogs sold by a company given the amount made by them and the total number of these snacks sold
We proceed as follows;
Let the amount of hotdogs sold be x and the amount of hamburgers sold be y.
We have a total of 300 snacks sold, mathematically;
x + y = 300 ..........(I)
Now let’s look at the prices.
x number of hotdogs sold at $2, this give a total of $2x hotdogs
y number of hamburgers sold at $3, this give a total of $3y.
Adding both to give total, we have ;
2x + 3y = 780.......(ii)
This means we have two equations to solve simultaneously. From equation 1, we can say x = 300 -y
Now let’s insert this in the second equation;
2(300-y) + 3y = 780
600-2y + 3y = 780
y = 780-600 = 180
Recall; x + y = 300
x = 300 -y
x = 300-180 = 120
The answer would be you can’t simplify the first one but the second would be 15 square root 5
Hope this helps
