Answer:
49 stones
Step-by-step explanation:
Write the following proportion based on the given ratio of marbles (m) to stones (s), and naming the unknown number of stones to find, with the letter "X":
6 m / 7 s = 42 m / X s
cross multiply to get the unknown in the numerator:
6 * X = 42 * 7
divide both sides by 6 to isolate X entirely on the left of the equal sign
X = ( 42 * 7 ) / 6
X = 49
Therefore, there are 49 stones
It looks like the limit you want to compute is
Since 
, this limit corresponds exactly to the derivative of 
at 
. Recall that
By the chain rule,
Since 
exists, 
is differentiable at so it must be continuous.
Answer:
The answer is 4!!
Step-by-step explanation:
A Passport picture is normally in the rectangular formation meaning, if the width of the top of the passport picture is 3, then the bottom is 3 as well.
That lets you figure out, since perimeter is all sides added together, 3+3 = 6 so 6 is both widths combine.
With this 6 in mind, if the perimeter of the entire passport is 14cm, and you have 6cm as both widths combine, now you need to find the length of this object.
Now here, since 6 is both widths combined, simply here you do 14cm - 6cm which is 8.
8 is the total length, meaning both sides added. See now that is the answer if you are finding out the total length (which is ha not the question).
Since you are trying to find only 1 side of the length, since there are 2 sides, you do 8 divided by 2, and BAM you get which is actually your answer as well!
PS. I don't even know if this is right though it should be right, use a calculator if you are doubtful :D
Happy New year!
Answer:
C. -20 and F. 20
Step-by-step explanation:
-20 x -20 = 400
20 x 20 = 400
Answer:
$55.07 Answer C is closest
Step-by-step explanation:
The original price of the 2 sweaters was 2($45.89) = $91.78
To find the price at 40% off, multiply this $91.78 by
1.00 - 0.40, or 0.60:
0.60($91.78) = $55.07 Answer C is closest.
