Box 1 = 6 & 3/8 kilograms.
Box 2 = 7 & 2/8 kilograms.
6 & 3/8 + 7 &2/8 = 13 & 5/8 kilograms.
Therefore the combined weight of the boxes are 13 & 5/8 kilograms.
Answer:
D. No, Jacob is not correct. The median amount he makes is $84.00 in a day.
Step-by-step explanation:
In this case, the mean is not the best measure of this data.
We can see that there is one value lower than the rest, $58. This brings the mean down.
With the value of $58, the mean is $80.70. If we were to take this value out, the mean would be $85.20, which is higher.
Since the mean is brought down by this value, we should use the median. The median of this data set is $84.
Answer:
i don.tget it
Step-by-step explanation:
Answer:
D)4x + 6/(x + 1)(x - 1)
Step-by-step explanation:
A field is basically a rectangle, so to find the perimeter of our field we are using the formula for the perimeter of a rectangle

where
is the perimeter
is the length
is the width
We know from our problem that the field has length 2/x + 1 and width 5/x^2 -1, so
and
.
Replacing values:


Notice that the denominator of the second fraction is a difference of squares, so we can factor it using the formula
where
is the first term and
is the second term. We can infer that
and
. So,
. Replacing that:


We can see that the common denominator of our fractions is
. Now we can simplify our fraction using the common denominator:




We can conclude that the perimeter of the field is D)4x + 6/(x + 1)(x - 1).
Answer: 60 degree
Explanation: The sum of the three interior angles of a triangle is always 180°.
180-80-40=60 degree.
