Answer:
12 pies
Step-by-step explanation:
To solve this problem, the best method will be to use a proportion! To set this proportion up, you must understand the values that the problem is giving you. The problem states that 7 cups of flour makes 3 pies. This wording tells us that those two values will both be on one side of the proportion. It does not matter which value is on top or bottom, as long as they are together on one side! For this problem, I'll set up the left side of the proportion like this:
Next, you'll include your third value and your x on the right side of the proportion. Make sure that your third value aligns with its matching value on the other side. For example, since our third value here is the 28 cups of flour, it must be on the bottom on the right side since your 7 cups of flour is on the bottom of the left side. This is what the proportion should now look like:
To solve, just cross multiply and divide! 3 times 28 is 84. Then, divide the 84 by the 7 and you'll get a final answer of 12 pies!
Let a = runner 2, a + 500 = runner 1.
a + (a + 500) = 5000
2a + 500 = 5000
2a = 4500
a = 2250
Runner 1 ran 2,750 meters. Runner 2 ran 2,250 meters.
Answer:
area is length x width multiply one side by the other
Step-by-step explanation:
Answer:
dr/dR= s/(s-r)
b) taking all values positive.. the answer is INCREASING
Step-by-step explanation:
a) R= r*s/(s+r)...
making r subject of formulae ... r = R*s/(s-r)
diff of (r) wrt R= s/(s-r)...
b) from the eqt R=r*s/(s-r)
and increase in r would always lead to an increase in R.. due to the multiplication power of the numerator. also with the condition that all values are positive..
