Answer:
3.6, 3.60
Step-by-step explanation:
Equivalent decimal numbers may have different numbers of trailing zeros.
_____
<em>Comments on equivalents</em>
The number can be written in several different forms, including ...
and variations on these.
As a straight standard-form decimal number this representation (3.600) indicates it has 4 significant figures. <em>There is no other equivalent standard-form decimal number that will convey the same information regarding significant figures</em>. The form in scientific notation above will convey that information because it retains the two trailing zeros.
The mixed numbers can be considered to have a precision matching that of the fraction, but when we're concerned about the precision of the answer, we usually use a decimal or scientific notation presentation.
Answer:
44
Step-by-step explanation:
If a serving size is 1/2 ounce, there are 2 servings (2/2) per ounce. Let's multiply this by the total ounces.
22 × 2 = 44
There are 44 servings in the bottle of ketchup.
gg easy
we want to cancel 1 term
first, get them into form am+bn=c where a, b, and c are constants
m-2n=2 is good
m+n=2(n-3) is m+n=2n-6 which is m-n=-6
compare constants
m's have 1 and 1
n's have -2 and -1
let's cancel m's
a. multiply 1st equation by -1
-m+2n=-2
add to 2nd equation
-m+2n=-2
<u>m-n=-6 +</u>
0m+n=-8
n=-8
sub back
m-n=-6
m-(-8)=-6
m+8=-6
m=-14
b. to check
m=-14 and n=-8
m-2n=2
-14-2(-8)=2
-14+16=2
2=2 yep
m-n=-6
-14-(-8)=-6
-14+8=-6
-6=-6 yep
so m=-14 and n=-8 is the solution
