Answer:
The answer would be 4 tablets.
Step-by-step explanation:
When read the question carefully you will divide 24 hour which is all the hours in the day. And six 24 divided by 6 equals 4 tablets each day.
Set proportions:
15/72 = x/60
Cross multiply:
15 * 60 = 72 * x
900 = 72x
Divide
12.5 = x
To start off, let's do the rectangle. So 3 times 6 is 18ft^2. One step done. Now we have to find the area of the triangle and add it to our other area to get the total area. The area of triangle is A=BH1/2. So since we used 3ft already, we have to subtract 15-3 which is 12. Since the length of the triangle does not extend all the way, we add 6 to 6, which is 12 ft. Now we can multiply 12 times 12, which is 144 ( according to A=BH times 1/2). Now we have to multiply 144 by 1/2, which is 144/2, which is 72ft^2. Now we can add the area of the rectangle by the area of the triangle to get the total area of the figure. So 72ft^2 * 18ft^2= 90ft^2. Therefore, the area of the entire figure is 90ft^2.
Answer:
Step-by-step explanation:
Recall that the perimeter of a shape is found by adding each of the sides together.
If the lengths of the sides are , then the perimeter would be
K/5 + 3 - 3k = -6k
Steps
Subtract 3 from both sides
k/5 + 3 - 3k - 3 = -6k - 3
Then simplify,
k/5 - 3k = -6k - 3
Add 6k to both sides
k/5 - 3k + 6k = -6k - 3 + 6k
Simplify,
k/5 + 3k = -3
Next, multiply both sides by 5
k/5 * 5 + 3k * 5 = -3 * 5
So,
k + 15k = -15
16k = -15
Then, divide both sides by 16
16k/16 = -15/16
Simplify,
k = -15/16
