A two-digit number read from left to right is 20% greater than the same number read from right to left. Find the number.
Answers
Final answer:
The number that is 20% larger when read from left to right than when read from right to left is 24.
Explanation:
The question asks for a two-digit number which is 20% larger when read from left to right than it is when read from right to left. Let's denote the digit in the tens place as 'a' and the one in the units place as 'b', then the two-digit number can be written as 10*a + b. When reversed, this becomes 10*b + a.
According to the question, 10*a + b is 20% (or 1.2 times) greater than 10*b + a. So, we can set up the following equation: 1.2(10*b + a) = 10*a + b.
When you solve this equation, the solution is a = 2 and b = 4, so the number the question is asking for is 24

The given pattern is a mathematical sequence where each number is obtained by multiplying the previous number by 9 and subtracting 1. The solution to the pattern is 8, 72, 647, 5822, 52499.
Explanation:
The given pattern is a mathematical sequence where each number is obtained by multiplying the previous number by 9 and subtracting 1. The pattern continues by multiplying the new number by 9 and subtracting 1 again.
Let's break down the steps for each number in the sequence:
- 1 x 9 - 1 = 8
- 8 x 9 - 1 = 72
- 72 x 9 - 1 = 647
- 647 x 9 - 1 = 5822
- 5822 x 9 - 1 = 52499
Therefore, the solution to the given pattern is 8, 72, 647, 5822, 52499.

Answer:
249.15 million
Step-by-step explanation:
151(1.65)=249.15
To calculate the US population in 1990, we increase the 1950 population of 151 million by 65%, resulting in an estimated population of about 249.15 million.
To answer the question, we need to find out how much the United States population increased from 1950 to 1990. We know that the US population in 1950 was 151 million and that it increased by 65% by 1990.
First, we need to calculate the amount that represents the 65% increase from 151 million. We can do this by multiplying 151 million by 65/100. This will give us about 98.15 million.
Then, we add this increase to the initial population in 1950, which gives us the 1990 population. So, if we add 98.15 million to 151 million, we get a 1990 population estimate of approximately 249.15 million.

Cost of goods available for is equal
80000+160000=240000
Retail value is equal
100000+200000=300000
This means that the cost of goods sold is 80% (240000÷300000) and gross profit is 20%
Sales= 250000 and it's cost is equal 200000 (250000×0.8)
Ending inventory
