Answer 1
The best measure of center is median
It’s value is 60
Answer 2
The best measure of the center is “median” this means middle number. The answer is 60.

Tip:
To find the median number organize the numbers from least to greatest, like this:

40 40 55 55 55 60 60 65 65 70 70 70

Now just cross the numbers in this order: right to left like this:

40 55 55 55 60 60 65 65 70 70

This way you should find the middle number. If you end up with two numbers as the middle you need to add them and divide by 2 to find the average of the two numbers.

Hope this helps!!

Solve for x

Answers

Answer:

x = 156

Step-by-step explanation:

These angles are supplementary so they add up to 180:

x - 5 + 29 = 180

x + 24 = 180

x = 156

Answer:

x = 156

Step-by-step explanation:

The line equals 180 degrees, and the angle 29 degrees is already given.

180-29 = 151

This means that the other angle must be 151 degrees.

(x - 5)°

If we replace 156 with x, we will get 151 degrees, so that means x = 156.

(156 - 5)° = 151°

51. Find the length of the unknown side x of this triangle, evaluate your answer to two decimal places.

Answers

Answer:

See work, below.

Step-by-step explanation:

The radius of this circle is 10 and so the diameter is 20.  The measure of the angle opposite side x is found as follows:

                      adj side

 cos theta = ------------------- = 18/20.  Find theta:

                      hypotenuse

theta = arccos 18/20 = 0.451 radian.

Now use the sine function to find x:

                                          x                       x

sin 0.451 radian      = ------------------- = ------------- = 0.651

                                    hypotenuse          20

which results in x = 20(0.651) = 13.02

x = 13.02 units

I should have used the Pythagorean Theorem up front.

18² + x² = 20² becomes x² = 400 - 324 = 76, and so x = √76 ≠ 8.72

Teresa is maintaining a campfire. she has kept the fire steadily burning 4 hours with 6 logs. She wants to know how many logs she need to keep the fire burning for 18 hours. Select the equations tessa can use, and determine the number of logs she needs to maintain the fire for 18 hours. Select all that apply.

A. X/6=4/18
B. X/6=18/4
C. X/18=6/4
D. X/4=18/6
E. 4/6=18/X

Answers

D. X/4=18/6

Step-by-step explanation:

Let x be the number of logs=18 hours

6 logs=4 hours

X*4=18*6

4x=108

x=27 logs

so therefore 27 logs are needed to keep the fire burning for 18 hours

The believe the answer is D

A. It shows the unit rate of the graph in hours per mile
B. It shows the unit rate of the graph in miles per hour.
C. It shows the time, in hours, it takes the towboats to travel in 1 mile.
D. It shows the distance traveled, in miles, by the towboat after 5.25 hours.

Answers

I think the Answer is D
The answer is B because the hours would be the bottom intervals of 1 and the distance traveled (in miles) is the constant of 5.25. So, overall in one hour, you would’ve traveled 5.25 miles. (It’s like driving a car... you’d be going at a speed of 5.25 mph (which is kinda slow).

Answer:   x = 30

=======================================================

Explanation:

If a regular polygon has n sides, then each interior angle has the measure of

i = 180(n-2)/n

In this case, we have n = 6 sides, so,

i = 180(n-2)/n

i = 180(6-2)/6

i = 120

Each interior angle of a regular hexagon is 120 degrees.

This means the bottom-right angle of the triangle is 120 degrees. The upper-right angle of that triangle is shown to be x degrees. The remaining angle is also x due to the triangle being isosceles (recall that regular hexagons have all sides the same length). Isosceles triangles have congruent base angles, which are opposite the congruent sides.

Use the fact that for any triangle, the three angles always add to 180, and we get...

x+120+x = 180

2x+120 = 180

2x = 180-120

2x = 60

x = 60/2

x = 30

X=30 fine the whole thing first

Calculate the area of each shape below. Figures are not drawn to scale.

Answers

Answer:

sorry its impossible to take out the ans of this

Answer:

A = 168 m²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 8 + 16 = 24 and h = 14 , then

A = [tex]\frac{1}{2}[/tex] × 24 × 14 = 12 × 14 = 168 m²

True or false: The cross section of a 3D object may look different depending on the direction (horizontal or vertical) of the cut.

Options:
True
False

Answers

True, because it’s not certain it will be symmetrical.

True, as there is no guarantee that it will be symmetrical.

What is Geometry?

Geometry is defined as the study of two-dimensional or three-dimensional figures like quadrilaterals, Triangles, circles their sides, and angles.

Symmetry is defined as if the object is cut by its center line the two cut parts should be the mirror image of each other so that we can call them symmetric to each other.

Depending on the cut's direction (horizontal or vertical), a 3D object's cross-section may appear differently.

Therefore, the given statement is true that the cross-section of a 3D object may look different depending on the direction (horizontal or vertical) of the cut.

I really need help finding the surface area

Answers

There are 4 triangles and the formula for the area of a triangle is 1/2BH so 11x10 is 110 and then take half of that and you’ll get 55. Since there are 4 triangles you need to then multiply that by 4 to get 220. And then you have to find the area of the square base which is 11x11 which will come out to 121. So you add the 220 and 121 to get 341.

Jade buys a blouse and a skirt for 34 of their original price. She pays a total of $31.50 for the two items. If the original price of the blouse is $18, what is the original price of the skirt?

Part A

Which equation represents the situation?
0.75s = 31.50
34(18s) = 31.50
0.75(s + 31.50) = 18
34(18 + s) = 31.50
Part B

Use the Distributive Property to solve the equation.

Answers

Answer:

`Part A:

D. 3/4(18 + s) = 31.50

Part B:

$36

Step-by-step explanation:

I think 34 is 3/4, is that right?

here, s is the cost of the skirt

Part A: The answer would be:

3/4(18) + 3/4(s) = 31.5 =

3/4(18 + s) = 31.5

Part B: 3/4(18) + 3/4(s) = 31.5

4.5 + 3/4s = 31.5

Subtract 4.5 from both sides:

3/4s = 27, 27 is the cost of the skirt now, but we need the original price.

multiply both sides by 4/3:

s = 36
