Answer:
36degrees
Step-by-step explanation:
2x + 26 = 3x + 21
2x - 3x = 21 - 26
-x = -5
x = 5
m<B = (3x+21)°
m<B = 3(5) + 21
m<B = 15+21
m<B = 36degrees

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

Answer:
46.65%
Step-by-step explanation:
Discount = $ 114.30
Discount percent = [tex]\frac{discount price}{Normal price}*100\\[/tex]
[tex]= \frac{114.30}{245}*100\\\\= 46.65[/tex]

Answer:
156 ft^3
Step-by-step explanation:
1) find the volume of the parallelepiped:
V = side^2 x height = 6^2 x 3 = 108 ft^3
2) find the base area of the pyramid:
base area = side^2 = 6^2 = 36 ft^2
3) find the volume of the pyramid:
V = (base area x height)/3 = (36 x 4)/3 = 48 ft^3
4) find the total volume
V = 108 + 48 = 156 ft^3
For the rectangular prism the volume would be:
6*6*3 which equals 108
For the top prism the volume is:
6*6*4 which equals 144
Add 144 and 108 and you should get 252.

Answer:

Step-by-step explanation:
Consider the value of y
If there is a common difference between consecutive terms then relationship is linear.
A 7, 12, 18
12 - 7 = 5 and 18 - 12 = 6 ← not common so not linear
B 8, 16, 24
16 - 8 = 8 and 24 - 16 = 8 ← common then linear
C 5, 7, 10
7 - 5 = 2 and 10 - 7 = 3 ← not common so not linear
D 4, 16, 30
16 - 4 = 12 and 30 - 16 = 14 ← not common so not linear
Thus table B represents a linear relationship

Which measure of spread is the most appropriate for the data set represented by the graph?
A. range
B. quartiles
C. interquartile range
D. mean absolute deviation
E. either range or interquartile range
Answers
The most appropriate for the data set represented by the graph is mean absolute deviation.
What is Mean absolute deviation (MAD)?It is a measure of variability or variation that indicates the average distance or average absolute distance between each data point or data value and the mean of a data set
We can calculate the variability of a data set by different measure thay include range, interquartile range, mean absolute deviation, standard deviation, etc.
Quartiles or ranges may be useful but they are limited as they tend to skip a lot of data in the group.
While, absolute deviation can help us get a more representative idea of spread for a data set like the one given in this question, where the elements have close difference.
Hence, the most appropriate for the data set represented by the graph is mean absolute deviation.

Benjamin believes that 1/2 % is equivalent to 50%. Is he correct? Why or why not? Please explain.
Answers
Answer:
Benjamin is correct.
Step-by-step explanation:
1/2 converted to a decimal (1 divided by 2) is 0.50, which when converted to a percentage is 50%.
1 ÷ 2 = 0.5
.5 × 100 = 50 ⇒ 50%
So, 1/2% = 50%
Also, 1/2 is 50%. So, that should automatically prove that he is correct.
