Step-by-step explanation:

50 = (3y + 5) ; y = 15

70 = (2x + 4) ; x = 33

33 + 15 = 48

Answer:

It is: C. x + y = 39

Step-by-step explanation:

Since the first angles are always added unless they are in a fraction, but since that is not the case they are added and gives 39.

And if you want to know the measures of x, y.

X: is 55º

Y: it is 79º

180(3)

540

Choice B, would be the correct answer.

The y's on choice A, C, D are not increasing by a constant rate. However, choice B the y's are increasing by 8 every time. Thus, choice B would be the correct answer. Hope this helps :)

Answer:

B

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

The kind of symmetry the figure given above posses is a line and point symmetry.

A point Symmetry also known as origin symmetry is a Symmetry which occurs when every part of an object has a matching part. That is, the same distance from the central point but in the opposite direction.

The objects looks the same when viewed from opposite directions.

A line of symmetry is a line that cuts a shape exactly into two equal half. That is, if you fold the shape along the line, both halves would match exactly.

Therefore, the figure given above has both point and line Symmetry.

Answer:

Step-by-step explanation:

you do the length x width x height

[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]

Step-by-step explanation:

The answer to the blank space in number 2 is 8 because you would need to take the bigger denominator and then divide it by the lower denominate to find out the equivalent fraction. And for number two, you would divide 28 by 7 which equals 4, so you then take 4 and take the numerator and multiply the numerator by 2, so that's 2 times 4 which is 8. So the answer 8 in the blank space. Since I already explained how to do it here, I'll just give you the rest of the answers.

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

Answer:

Explained below...

Step-by-step explanation:

So, I believe that for the first question, you are finding the volume. Volume is what makes up the inside of a 3- dimensional shape.

So, as you may know, the formula for volume is length x width x height.

This means you will multiply 1, 4, and 6 feet. (1 * 4 * 6, which equals 24) So, I would say 24 pounds? I am unsure, but I hope this helps!

For question 2, you will have to find the area of each rectangle. With a concluding fact that the opposing sides are similar, this will make things easier.

First, locate all of your measurements for area (A = l * w) So, for the smaller rectangle, or two short sides, you will multiply 1 by 4, which is 4. For the longer sides, you will multiply 1 by 6, which is 6. For the top and bottom, you will multiply 6 by 4, which is 24.

Don't forget to remember that there are two of each rectangle!

Considering he will have to cover a total of 68 feet, I am sadly unsure of how many.

Hope this helps! :)

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.

The most appropriate for the data set represented by the graph is mean absolute deviation.

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.
