Notice that form 3 pm to 6:30 pm 3.5 hours have passed.
Since the function
represent the average number of cars that pass through an intersection x hours after 3:00 p.m, we are going to replace
with 3.5 to find <span>the average number of cars that pass through the intersection at 6:30 p.m
</span>
We can conclude that the <span>average number of cars that pass through an intersection at 6:30 pm is approximately 117. </span>
Answer:
x=2.1
Step-by-step explanation:
we are given with values z = 4.0 and y = 8.4
Substitute the given values in the equation and solve for x
Plug in 4.0 for z and 8.4 for y in the equation
multiply x on both sides
divide both sides by 4.0
x=2.1
Answer:
New CP = Rs 387.5
Step-by-step explanation:
Cost Price = Rs. 500
Loss %age = 10% of 500
So, Loss = Rs 50
<u><em>Finding the selling price:</em></u>
Selling Price = CP - Loss
SP = 500 - 50
SP = Rs 450
Now, The fruit seller wants to gain a profit of 12.5% without changing the selling Price:
<u><em>Firstly, Let's talk about the Profit :</em></u>
Profit %age = 12.5% of 500
Profit = 12.5 * 5
Profit = Rs 62.5
He wants to gain a profit of Rs 62.5
<u><em>So, The cost Price</em></u>
The cost price would be reduced by Rs 62.5
New CP = 450 - 62.5
New CP = Rs 387.5
First find how many units of solution there is:
500* 2% = 500(.02) = 10 units
You need 10 units of solution in 'x' units of a 10% solution.
x*10% = 0.1x = 10 units -----> x = 10/0.1 = 100
100 units are needed
Answer:
247
Step-by-step explanation:
1,4,11,26,57,120. see the pattern that emerges from the series:
4–1 = 3; 3–1 = 2 = 2^1
11–4 = 7; 7 - 3 = 4 = 2^2
26 - 11 = 15; 15 - 7 = 8 = 2^3
57 - 26 = 31; 31 - 15 = 16 = 2^4
120 - 57 = 63; 63 - 31 = 32 = 2^5
so the next number should be 64+63 = 127+120 = 247.
check: 247–120 = 127; 127–63 = 64 = 2^6. correct.
so the next number is 247. 2^n+(n-1)
