Answer:
The required rate of interest = 14.285%
Step-by-step explanation:
Here, The principal amount = 7,000
The final paid amount = 9,000
Time = 2 years
Let us assume the rate of interest = R
Now, Simple Interest = Amount - Principal
= 9,000 - 7,000 = 2,000
So, the SI on the given principal for 2 years = 2,000

or, R = 14.285%
Hence, the required rate of interest = 14.285%
Rates are used to measure a quantity over another.
<em>The 1.8 million cars use </em>
<em> liters each year</em>
Given

--- distance

First, we calculate the number (n) of gallons used by each car

Solve for n

So, we have:


Convert miles to kilometers



The number of gallons (N), used by all the cars is:


Convert to liters


In scientific notation to 2 decimal places, we have:

<em>Hence, the number of liters used is </em>

Answer:
So there are 500 pairs of numbers that have a sum of 1001. Thus, the sum of numbers from 1 to 1000 is 500*1001 = 500,500.
Step-by-step explanation:
Answer:
y= 34/23
x= 123/46
Step-by-step explanation:
Solve for x
8x-5y= 14
x= 14/8 +5/8y
Sub x into second equation
– 5х+бу = -3
-5(14/8 +5/8y) + 6y= -3
-29/4 +23/8y = -3
y= 34/23
Sub y into any equation and solve for x
8x=483/23
x= 123/46
The answer is 13/85. You could find out the answer by doing the reprical multiplication.
