Answer:

Step-by-step explanation: Arrange your numbers in numerical order.

Count how many numbers you have.

If you have an odd number, divide by 2 and round up to get the position of the median number.

If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

\huge\text{Hey there!}

\large\text{When you see or hear the word \underline{median} think of its asking you}\\\large\text{\underline{what number is in the MIDDLE?} or it’s asking for the \underline{middle number}}

\large\text{Some people can easily find the median by putting your given numbers}\\\large\text{from least (smallest) to greatest (biggest)}}

\large\text{49, 50, 51, 55, 58, 59,  63}

\large\text{Make sure that you have the SAME amount in each sides of your numbers}

\large\text{The median in this given set seems to \underline{55} because it has 3}\\\large\text {numbers on each sides of it.}

\boxed{\boxed{\large\text{Answer: \huge \bf 55}}}\huge\checkmark

\text{Good luck on your assignment and enjoy your day!}

The diagram shows 3 identical circles inside a rectangle.
Ilya [14]

Answer:

11700 mm²

Step-by-step explanation:

A rectangle is a quadrilateral with two equal, opposite and parallel sides. Each of the angles in a rectangle is 90°.

The horizontal distance of the rectangle = r + r + r + r = 4r

The vertical distance = r + h + r = 2r + h

Where h is the distance between the midpoint of the 2 up circles and the midpoint of the down circle.

Using Pythagoras:

 (2r)² = h² + r²

h² + r² = 4r²

h² = 3r²

h = √3r²

h = r√3

Vertical distance = 2r + h = 2r + r√3

Area of rectangle = vertical distance * horizontal distance

Area = 4r * (2r + r√3) = 8r² + 4r²√3 = 4r²(2 + √3)

Substituting:

Area = 4r²(2 + √3) = 4(28²)(2 + √3) = 11703.711 mm²

Area = 11700 mm² to 3 s.f

Need help ASAP! Directions in picture ;)
Len [333]

Answer:

<h2>112°</h2>

Step-by-step explanation:

Angle 8 will also be 112° because both of them( Angle 2 and Angle 8) are exterior alternate angles and exterior alternate angles are always equal.

So Angle 8 = 112°

Which expression can be used to find the surface area of the following triangular prism?
Orlov [11]

Answer:

214.

Step-by-step explanation:

To get Surface area take

(cross section area) × 2 +(perimeter of crossection area × length)

the cross section area is a triangle

so area of a triangle =1/2 base times height

1/2×8×2=8

let's get perimeter of cross section

the cross section is still at triangle so let's find its perimeter.

5+5+8=18

18×length of which is 11

18×11=198

and 188 + 16=214. that's the answer

maybe you can get a expression from the work that I've just done cuz I can't see the answers clearly in the picture you have taken.if you don't mind just send the picture back then I'll get the answer.

From the above question:

5 people = 3 pounds of tomatoes

the table describes some of the solutions of the inequality 3m&gt;21. Which graph best describes the solutions of 3m&gt;21?
Travka [436]

Answer:

Option 3

Step-by-step explanation:

Given inequality is,

3m\geq 21

To find the solutions of the given inequality solve this inequality first.

\frac{3m}{3}\geq \frac{21}{3}

m\geq 7

This inequality will be represented by an arrow starting from 7 and directing towards infinity.

Since, inequality is having a sign notation of greater than equal to, arrow will start with a dark circle located at 7.

Therefore, Option 3 (from the top) will be the answer.
