Since we are rounding to the nearest inch, we want to look at the tenths place. The rule for rounding is 5 and up, we round up, 4 and below, stay. Since 3 is below 5, we stay. Therefore your answer should be 66 inches of precipitation. Hope this helps!

Rounded to the nearest inch, there are 66 inches or precipitation.

Look at the numbers after the decimal point. Do they round up or down? In normal circumstances, would it round to 0, or to 100? It wouldn't round to 100. Anything 50 and above would round to 100, and this is not 50, nor is it more than 50.

So this rounds to the previous number, which is 66.

An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 50 g of an alloy containing 12% copper with 78 g

givi [52]

Given :

An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 50 g of an alloy containing 12% copper with 78 g of an alloy containing 92% copper.

To Find :

How many grams of copper are in the resulting mixture what percentage of the resulting mixture is copper.

Solution :

Mass of copper in 50 gm alloy = $50\times 0.12 = 6\ gram$ .

Mass of copper in 78 gm alloy = $78\times 0.98 = 76.44\ gram$ .

Total mass of copper, ( 6 + 76.44 ) gm = 82.44 gram.

Percentage of copper in resulting mixture :

$\%=\dfrac{82.44}{50+78}\\\\\%=64.4\ \%$

Hence, this is the required solution.

How many 3 digit palindromes are divisible by 9?

ludmilkaskok [199]

Interesting problem.

A palindrome is a number which is identical when read/interpreted left-to-right or right-to-left. For example, 14241 is a palindrome, so is 444444.

A three digit palindrome must be made up of two distinct digits only, one for the first and last digits, and one for the middle, for example, 424, or 515, etc.

For a number to be divisible by 9, the sum of the digits must add up to a multiple of 9, such as 0, 9, 18, 27, etc.

We can now form a table of the possible 3-digit palindromes divisible by 9, starting with the first/last digits (=A), and finding the middle digit (=B). The number is therefore represented by the pattern ABA.

For example, when A=1, we have the number 1B1. For the number to be divisible by 9, B=7 so that sum=1+7+1=9, which is divisible by 9.

For each value of A (from 1 to 9) we can only find one value of B that makes the number divisible by 9. Thus we can only find nine such numbers, with A equal to 1 to 9.

Here's a list of the numbers

A B number
