Answer:
594
Step-by-step explanation:
To find the area of a rectangle it is length * width
First break the shape into two shapes that are both rectangle
The find the length of the line on the tallest part, subtract 30 with 14
30 - 14 = 16
Lets first solve the taller one
16 * 24 = 384
Then solve the one on the left
14 * 15 = 210
Then add the both together to get the total area of the two shapes together
384 + 210 = 594
594 is your answer
The number would be 12. If you substitute you will find that 12 is correct.
Answer:
4 Hours
Step-by-step explanation:
Let's say that the rate of the machines 1/x, because every time they complete an order, it takes them x hours. To find x, we have to add the the rates of the individual machines, which would equal the rate of the machines working together. We know that there are four machines working together at the same rate, and it took them 32 hours.
So:
1/x + 1/x + 1/x + 1/x = 1/32
1/4x = 1/32
4x = 32
x = 8
Thus, the rate of the machines is 1/8.
Now we have to find the time of the order with only half of the machines working together. This time, we don't know the combined rate, so I'll substitute it for y.
1/8 + 1/8 = 1/y
1/4 = 1/y
y = 4
The time taken to complete it is 4 hours.
