Answer:
Step-by-step explanation:
From the question we are told that:
Table for price per Kg
Watermelon Rs 18.50
Cherry Rs 72
Grapes Rs 120.60
Apples Rs 78.40
Karan Bought:
412 kg watermelon
1 kg 200g cherries
250 g grapes
134 kg apples
Generally the equation for Total Price of Fruits Bought is mathematically given by
\sum (Price Rs* Weight kg )
Therefore the Amount of Money he gets back is
Therefore
He owes the shop keeper 2.74 million Rs
Answer:
15n
Step-by-step explanation:
Given
The above table
Required
The formula of the table
First, calculate the slope (m)
Where:
<em>n = Number of Lawns</em>
<em>y = Earnings</em>
So, we have:
The equation is then calculated as:
This gives:
Hence:
<em>B is correct</em>
Answer:check the pic
Step-by-step explanation:
The intervals apply to the x column. And f(x) is just a different way of saying y. So when y is greater than 0 on the chart, what is true about x. So far as I can tell, the second and last choices are correct.
Answer:
160 mph
Step-by-step explanation:
The relationship between time, speed, and distance is ...
time = distance/speed
__
If p represents the plane's speed, then the speed with the wind is p+20 and the time to go 405 miles is ...
405/(p+20)
The speed against the wind is p-20, and the time to go 315 miles is ...
315/(p-20)
These two times are equal, so we have ...
405/(p+20) = 315/(p-20)
405(p-20) = 315(p+20) . . . . . . cross multiply
90p = 6300 +8100 = 14400 . . . . add 8100 -315p
p = 14400/90 = 160
The speed of the plane in still air is 160 mph.
