Answer:
D: -86.156
F: -3
Step-by-step explanation:
D: Convert Mixed numbers to improper fractions then remove the parenthesis and multiply the fractions. Next you have to multiply the numbers then again multiply the fractions. And once more you Multiply the numbers and finally you have to divide the numbers to get your answer.
F: Convert mixed numbers to improper fractions then cancel out whats not needed Which also means cross-cancel common factor: 4 then apply the rule a(-b)=-ab. Then again you cross-cancel common factor: 2 then last for this you will divide to get your answer.

Answer:
1, 2
Step-by-step explanation:
Increasing the compass by 1cm increases the radius by 1cm also, because one end of the compass is the centre of the circle, and the other end rotates around it.
However, this increases the diameter by 2cm, because the diameter of a circle is always 2 times its radius.

How much liquid is in the measuring cup? You must put the units in your answer. If the units are standard, answer with fractions. If the units are metric, answer with decimals.
Answer:
7/8 cups
Step-by-step explanation:
since there are 8 tick marks between each cups, we know that we are counting by 1/8ths. 1/2 can also be 4/8 in this situation but since the liquid passed that mark we can start counting from there.

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

10 POINTS PLEASE HELP the arthemitic mean of 5, 10, 15, and z is 20. what is z
Answer:
z = 50
Step-by-step explanation:
There are 4 numbers in total (5,10,15,z)
The mean is when you get the total of all the numbers and divide by how many there are
If you do the inverse then that means that 20 x 4 = total of all 4 numbers
80 = 15 + 10 + 5 + z
80 = 30 + z
z = 80 - 30
z = 50
You can check you answer at the end

A little help here? And can anyone explain this?
Answer:
D.
Step-by-step explanation:
According to the dot plot,
3 students spend 0.5 minutes brushing their teeth.
2 students spend 1.5 minutes brushing their teeth.
1 student spends 2.5 minutes brushing their teeth.
2 students spend 3.5 minutes brushing their teeth.
1 students spend 4 minutes brushing their teeth.
So, the number set will be: {0.5, 0.5, 0.5, 1.5, 1.5, 2.5, 3.5, 3.5, 4}
Median: The middle number in a set that is ordered from least to greatest.
In this example, the median is 1.5
Mean: The sum of all values divided by the number of values.
In this set there are 9 values so we’ll divide the sum by 9
In this example, the mean would be:
(0.5 + 0.5 + 0.5 + 1.5 + 1.5 + 2.5 + 3.5 + 3.5 + 4) ÷ 9
18 ÷ 9 = 2
If we compare the mean to the median we can see that the mean is greater because 2 > 1.5

y=?
Explain?
Answer:
-3
Step-by-step explanation:
\((5(-3)+4= -15+4=-11) (2(-3)-5=-6-5=-11)(-11=-11)\)
Answer:
y = -3
Step-by-step explanation:
Isolate y
5y + 4 = 2y - 5
subtract y from both equations
3y + 4 = -5
Add 5 to both sides
3y +9 = 0
subtract 9 from both sides
3y = -9
divide both sides by 3
y = -3

In the rectangle below, the line MN cuts the rectangle into two regions. Find x, the length of segment NB, so that the area of the quadrilateral MNBC is 40% of the total area of the rectangle.
The length of segment NB is 0.833
Finding x, the length of segment NBFrom the question, we have the following parameters that can be used in our computation:
The rectangle
The area of the rectangle is
Area = (20 + x) * 10
The area of MNBC is
Area = 1/2 * 10 * (x + 20 + x - 5)
Area = 5(2x + 15 )
The area of the quadrilateral MNBC is 40% of the total area of the rectangle
So, we have
5(2x + 15) = 40% * (20 + x) * 10
5(2x + 15) = 4* (20 + x)
When evaluated, we have
x = 0.833

Step-by-step explanation:
The total area of the rectangle is 20x10=200
so the area of MNBC is: 40%x200=80
MC= 20-5=15
so (x+15).10/2=80 (according to the trapezoidal area formula)

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide
Answer:
To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.
Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).
Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).
To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
First, find out how much stickers you can put on the long side:
12/3 = 4
Next, find out how much stickers you can put on the wide side:
8/2 = 4
Lastly, calculate them together:
4x4=16
So the answer is 16.

Find the height and area of an equilateral triangle with side lengths of 10 cm.
Height:____cm
Area:______cm²
PLEASE HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
\(Area = 25\sqrt{3}\)
\(Height = 5\sqrt{3}\)
To find the height and area of an equilateral triangle we can start by finding the area using the following equation
\(Area =\frac{\sqrt{3}}{4} side^2\\Area =\frac{\sqrt{3}}{4} 10^2\\Area =\frac{\sqrt{3}}{4} 100\\\)
Which then simplifies down to
\(Area = 25\sqrt{3}\)
Next, we can find the height using the following equation
\(Height = \frac{side\sqrt{3} }{2} \\Height = \frac{10\sqrt{3} }{2}\)
which then simplifies down to
\(Height = 5\sqrt{3}\)

I need help arranging cards in a 4 x 4 grid with numbers 1-9 so that the sum of each row and each column is 20. This what the grid looks like:
Answer:
8, 2, 8, 2
7, 3, 7, 3
6, 4 6, 4
9, 1, 9, 1
Step-by-step explanation:
In the picture, it shows two of each number so I'm gonna base it off the picture but let me know if I should base it off the wording.
So we know that half of 20 is 10. This will be valuable information. So we need the sum of two numbers to equal 10. So for the rows we can just do 8+2+8+2, 7+3+7+3, 6+4+6+4, 9+1+9+1.
Since there are 18 numbers, I'm assuming we don't have to use all of them.
