Ok so find the median so put the numbers in order so 82,83,84,85,85,86,86,86,87,87,88,89,90
then start from both sides cross off from both dies at the same time
83,84,85,85,86,86,86,87,87,88,89

84,85,85,86,86,86,87,87,88

85,85,86,86,86,87,87

85,86,86,86,87

85,86,86,86

86,86

so... 86 is the answer. i know its long but its the whole work hope it helped.

Which of the following expressions is equal to 5^6/5^2

Natali5045456 [20]

Answer:

$\dfrac{5^6}{5^2}$ = $5{\cdot}5{\cdot}5{\cdot}5$

Step-by-step explanation:

The given expression is :

$\dfrac{5^6}{5^2}$

We need to find this expression is equal to what.

$\dfrac{5^6}{5^2}=\dfrac{5^4\times 5^2}{5^2}\\\\=5^4\\\\=5\times 5\times 5\times 5\\\\\text{or}\\\\=5{\cdot}5{\cdot}5{\cdot}5$

Hence, $\dfrac{5^6}{5^2}$ is equal to $5{\cdot}5{\cdot}5{\cdot}5$ . Hence, the correct option is (c).

A square has an area of 64 square meters.

34kurt

Answer:

Side is 8 meters, Perimeter is 32 meters

Step-by-step explanation:

One side

Squares have 4 equal sides. Area is found using l*w, but the sides are all equal in squares. Therefore, the area can be found using:

a=s^2

We know the area is 64, so we can substitute that in

64=s^2

Take the square root of both sides

$\sqrt{64}=\sqrt{s^2}$

8=s

One side is 8 meters

Perimeter

Squares have 4 equal sides, and the perimeter is all the sides added up.

p=s+s+s+s

We know the side is 8, so we can substitute that in

p=8+8+8+8

p=4*8

p= 32

The perimeter is 32 meters

If f(x)=4x-7 and g(x)=2x+4 evalvate f(x)+g(x) for x=-3

galben [10]

Answer:

-21

Step-by-step explanation:

We are told to find f(x) + g(x) for x= -3. Therefore, we must evaluate f(-3) and g(-3), then add them together.

First, evaluate f(-3).

f(x)=4x-7

To find f(-3), we need to substitute -3 in for x.

f(-3)= 4(-3)-7

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction First, multiply 4 and -3.

f(-3)= -12-7

Next, subtract 7 from -12

f(-3)= -19

Next, find g(-3).

g(x)=2x+4

To find g(-3), substitute -3 in for x.

g(-3)= 2(-3)+4

Solve according to PEMDAS. First, multiply 2 and -3.

g(-3)= -6+4

Next, add -6 and 4

g(-3)= -2

Now, we can add f(-3) and g(-3) together.

f(-3) + g(-3)

f(-3)= -19

g(-3)= -2

-19 + -2

Add

-21

Help me please I am completely lost

Irina-Kira [14]

Okay, your answer is 182. You really do not need to look at the crazy stuff on the paper about the crazy numbers. Look at the graph. It is counting up by 20's on the left side. But on the right side, the whole time it is counting up by 13's. Your answer is 182.
