What is addition?

Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.

Here, we have,

now, we get,

 136

+212

=348

I didn't regroup because 6+2, 3+1, and 1+2 don't have answers that contain two digits. Two digit number answers need to be regrouped.

Hence, the sum is 348.

A.

earnings=bonus+pay
pay=pay per hour times number of hours
h=number of hours
9.5=pay per hour
pay=9.5h
bonus=60

earnings=9.5h+60
at least 460
greater than or equal to 460
9.5h+60>460

B. solve for h
9.5h+60>460
subtract 60
9.5h>400
divide oth sides by 9.5
h>42.1
at least 42.1 hour (about 42 hours and 6 minutes, if the job is rounding, then say 43 hours)

What js the value of the expression 10 -16÷2​

Answers

16÷2=8 then 10_8=2 the answer is 2

Final answer:

The value of the expression '10 - 16 ÷ 2' is determined by first performing the operation of division, then subtracting that result from the remaining number. The value of this mathematical expression is 2.

Explanation:

The subject of your question is Mathematics, specifically an arithmetic order of operations problem. This question falls under the Middle School level. The expression given with the question is 10 -16÷2.

In mathematics, when you are solving such expressions, the order of operation matters. The precedence rules that define the order of operations state that division and multiplication (whichever appears left to right) have higher precedence than addition and subtraction. This rule is often remembered with the acronym PEMDAS, which stands for Parentheses, Exponentiation, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Using these rules, we first perform the operation of division (16 ÷ 2). The result of that division is 8. The next step is to subtract that result from 10.  So, it will be 10 - 8 and we obtain a value of 2 for the expression.

What is the greatest common factor of 32 and 48

Answers

Turn each number into the product of it's prime factors.

32=16x2=2x2x2x2x2=2^5

48=24*2=6x4x2=2x3x2x2x2

Pick the highest number that occurs. In this case it is 2. Now we have to see how many times it appears in both. It appears 5 times in 32 and 4 times in 48. 4 is the highest number of times it appears in the numbers so:

2^4=2x2x2x2=16

The Greatest Common Factor (GCF) of 32 and 48 is 16.
The factors for 32 are −32,−16,−8,−4,−2,−1,1,2,4,8,16,32.

The factors for 48 are −48,−24,−16,−12,−8,−6,−4,−3,−2,−1,1,2,3,4,6,8,12,16,24,48.
