3=111

Step-by-step explanation:

Answer:

The median of a list of numbers is the center number when you order the numbers from least to greatest.

Since there are 9 numbers; the center number is the fifth number. Four numbers below and four numbers above. Median is 4.44 and the mean or average is 4.09.

Step-by-step explanation:

List in order from least to greatest

(3.25, 3.25, 3.66, 3.83)  4.44  ( 4.52, 4.57, 4.69, 4.74) Notice 4 numbers below 4.44 are lower and 4 numbers above 4.44 are higher.  So the median number is 4.44

For the mean you add all the number and divide the sum by the number of numbers you have. We know you have 9 numbers from the first part. So, add the numbers from the list (3.25 +3.25+ 3.66 + 3.83 + 4.44 + 4.52 + 4.47 + 4.69 + 4.74)  = 36.85  Then divide by 9 = 4.09

You need to give us the choices. However, I will try and give you the answer.

The highest common factor is 8

8(x^2 - 3)     This is the answer I think the question expects.

8(x - √3 )(x + √3)  this is also possible

-30÷5=-6

this is the ans

Answer:

The answer is below

Step-by-step explanation:

The volume of a box with a length of l, width of w and a height of h is given by the formula:

volume of the box = length * width * height = lwh

The volume of a cylinder with a height of h, and radius r is given by the formula:

volume of the cylinder = π * radius² * height = πr²h

Since the box and the cylinder have the same height and the cylinder is wide enough for the box to be placed inside, this means that the box has a volume greater than that of the cylinder. Hence:

If the box can take 8 cups, the cylinder would be able to take 10 cups.

Step-by-step explanation:

Answer: A is right. B is acute, C is obtuse, and D is right.

Step-by-step explanation:

The right triangles have the square in the corner.

Triangle C is a little bit bigger than a right triangle.

Triangle B is acute because its smaller than a right triangle.

the total no of population=1650

13:17 first add the two numbers 13+17=30

then 13/30×y =715 , i make 13 at the numerator because it's males ratio

after that 30/13×13/30y =715 ×30/13

y =715×30/13

y =1650

after u find the total no it's simple to find the no of females

17/30×1650=935

Option 2  [tex]\frac{4\sqrt{6} }{3}[/tex]

Step-by-step explanation:

[tex]\frac{4\sqrt{2} }{\sqrt{3} } = \frac{4\sqrt{2} \sqrt{3} }{\sqrt{3}\sqrt{3} } = \frac{4\sqrt{6} }{3}[/tex]

Answer:

15/28 loads of laundry needs to be washed.

Step-by-step explanation:

Answer:

I love Math anyways

The ans is in the picture with the  steps how i got it

(hope this helps can i plz have brainlist :D hehe)

Step-by-step explanation:

Answer:

1. Move the variables to one side: 3(-4+4) = -3n

2. Distribute. You will end up with 0 = -3n

3. Divide both sides by -3. n = 0

Step-by-step explanation:

Answer:

n=0

Step-by-step explanation:

3(-4+4)+5n=2n

first distribute

-12+12+5n=2n

combine like terms

5n=2n

subtract 2n on both sides

3n=0

divide by 3 on both sides

n=0/3

which is also equal to

n=0

Answer:

X=1

Step-by-step explanation:

Answer:

x = 36°

Step-by-step explanation:

x + 20° + 4x = 200° { exterior angle of a triangle is equal to the sum of two opposite interior angles }

5x = 200° - 20°

5x = 180°

x = 180° / 5

x = 36°

Hope it will help :)

Answer:

5.5

Step-by-step explanation:

2x -3 = 8

then

2x = 8 + 3 = 11

means

2x = 11

then

x = 11 ÷ 2

x = 5.5

___________________

we change the sign (- or +)

then take the number to the other side of the equal (with the changed sign)

leaving the x alone so that we can answer the equation..

to make sure

2×5.5 -3 = .....

it will be 8

Answer:

[tex]2.5h = 3g[/tex]

Step-by-step explanation:

Given

[tex]Sugar = 2\frac{1}{2}\ cups[/tex]

[tex]Bars = 3\ pans[/tex]

Required

Determine the equation for h pans and g cups

We have that:

[tex]Sugar = g[/tex]

[tex]Bars = h[/tex]

To do this, we make use of the following equivalent ratios.

[tex]Bars : Sugar = Bars : Sugar[/tex]

So, we have:

[tex]3 : 2\frac{1}{2} = h : g[/tex]

Express fraction as decimal

[tex]3 : 2.5 = h : g[/tex]

Express as fraction

[tex]\frac{3}{2.5} = \frac{h}{g}[/tex]

Cross multiply

[tex]2.5h = 3g[/tex]

Answer:

4 cubes will be shown in the right view of the model and the 1st option is the top view for the model.

Answer:

204

Step-by-step explanation:

The area of the top triangle = 5*12/2 =                        30

The area of the bottom triangle =                                30

The hypotenuse of the top triangle is

5^2 + 12^2 = hypotenuse^2

25 + 144 = hypotenuse^2

169 = hypotenuse squared.

hypotenuse = sqrt(169)

hypotenuse = 13

Now the back face = 13 * 8 =                                       104

The area of the left side rectangular  face = 5*8 =     40

The total area = 30 + 30 + 104 + 40 =                        204

Answer:

It is the second one.

Step-by-step explanation:

a and e are equal because they are mirrored. d and b are equal because they are on the same  line and at the same point where the parallel lines go through. b and f are also mirrored. That leaves c and e which don't match.

Answer:

160yds²

Step-by-step explanation:
