Answer:
140 oranges
Step-by-step explanation:
From the Question, we know that the pyramid has 7 layers
The number of oranges in the first layer is = 1
Hence, the number of oranges in a pile is calculated as:
1² + 2² + 3² + 4² + 5² + 6² + 7²
= 1 + 4 + 9 + 16 + 25 + 36 + 49
= 140 oranges
Answer:
y=1/2x+5/2
Step-by-step explanation:
4-3=1
3-1=2
m=1/2x
So now you have y=1/2x
Insert into equation
y=1/2x+?
Now sub you slope in to last points, and you get 5/2
So now you final answer is:
y=1/2x+5/2
Answer:
6.42$
Step-by-step explanation:
6.00 divided by 100 equals 0.6 multiplied by 7 equals 0.42 so the sales tax is 0.42 cents and the total is 6.42$
Answer:
To the nearest hundredth, the rate of flow will be 75.38 mm/hr
Step-by-step explanation:
Here in this case, we are to express the rate at which the water flow and round it up to the nearest hundredth.
We are told that water flows through the pipe at a rate of 490 mm every 6.5 hours.
Now, the rate will be 490/6.5 = 75.384615384615 mm/hr
Rounding this value to the nearest hundredth, we have 75.38 mm/hr
Answer: The answer is 1.5
Step-by-step explanation: First you want to add 5x + x which equals 6x. Then you want to add -5+-4 which = -9. Then you add 9 to the -9 to get rid of it. But you have to do it on both sides so you add 9+0 which =9. Finally you divide 9 by 6 which equals 1.5
