Who's gonna answer my last math question??

Answer:

Add 4 to both sides of the equation

8n-4=52

8n-4+_4=52+_4

Answer: x>9

Step-by-step explanation:

3 < x/2+1  

switch sides: x/2+1 > 3

Multiply sides by 3: 3x/2+1 > 3*3

Simplify: x>9

Answer:

The 3rd table

Step-by-step explanation:

The x values are dividing by 5 to  get the y values. The table is proportional because it's a pattern not just random values.

100 - 16 = 84

.84*573 = 481.32

which is more than 458.40

Answer:

A = 64 pi

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

The radius is 8

A = pi * 8^2

A = 64 pi

[tex] \huge \huge \huge\square[/tex]

Here All Sides Are Equal So,

Area = side × side= side²

So Assuming Side As 'l'

so, l×l = l²

Answer:

x = 3 and y = 6

Step-by-step explanation:

The given equations are :

2x-y=0 ......(1)

3x-2y=-3 .....(2)

We need to solve equations (1) and (2).

Equation (1) can be written as :

2x = y

Put the value of y in equation (2)

3x-2(2x)=-3

3x-4x = -3

-x = -3

x = 3

Put the valye of x in equation (1)

2(3)-y=0

y = 6

Hence, the value of x = 3 and y = 6.

Answer:

$16

Step-by-step explanation:

Given data

Total amount= $132,624

Cost of each hard drive=  $112

Total number of hard drive=1184

Cost of all the hard drives=  112*1184

Cost of all the hard drives=$132608

Balance will be= 132,624-132608

Balance will be= $16

Answer:

857.766cm^3

Step-by-step explanation:

Given data

Lenght = 3m

Internal radius r = 3m

External radius R= 10m

Volume of pipe= πr^2h

Volume of metal= External - Internal

Volume= πR^2h-πr^2h

Volume= πh(R^2-r^2)

Volume= 3.142*3(10^2-3^2)

Volume= 3.142*3(100-9)

Volume= 9.426*(91)

Volume= 857.766cm^3

Hence the volume of the metal is 857.766cm^3

Answer:

-1/2

Step-by-step explanation:

Find the slope by rearranging the equation into y = mx + b form, where m is the slope.

2x + 4y = -16

Subtract 2x from both sides:

4y = -2x - 16

Divide each side by 4:

y = -1/2x - 4

So, the slope is -1/2.

Step-by-step explanation:

C.

[tex]30x^2 + 44x +16 = 0\\\\2(15x^2 + 22 + 8) = 0\\\\2(15x^2 + 12x + 10x + 8) = 0\\\\2(3x(5x + 4)+2(5x + 4))=0\\\\2((3x + 2)(5x + 4)) = 0\\\\Zeroes : 3x + 2 = 0 => x = \frac{-2}{3}\\[/tex]

             [tex]5x+ 4 = 0 => x = \frac{-4}{5}[/tex]

Point (2, 5)

Point (6, 7)

Step 2: Find slope m

Answer:

Step-by-step explanation:

since it's a square we know the two sides are equal.  So set them equal and solve for X

a)

4x + 3 = 3x +17

4x-3x = 17 -3

x = 14

Since we now know X  plug it into the expression for the angle

b)

5(14) + 4y = 90    ( 90°  b/c we know the angle is equal to that )

70 4y = 90

4y = 90-70

4y = 20

y = 20/4

y = 5

c)

we can find the perimeter by just plugging in X to either of the expressions for the side and then multiplying that by 4,  since there are 4 sides

4(14) +3

56 +3

59

now times 4 for each side

59*4= 236

Answer:

The answer is "The Last choice".

Step-by-step explanation:

Please find the complete question in the attached file.

It is the phrase that perfectly represents the usage of a simulation for an estimate of the likelihood of the birthday of 2 randomly chosen persons on a Monday.

In a week there are 7 days, so seven choices are available, and just one Monday. Therefore, it is probable that [tex]\frac{1}{7}[/tex] will occur on a Monday to a birthday individual.

The first person will have a probability [tex]\frac{1}{7}[/tex].

The second person also has a probability [tex]\frac{1}{7}[/tex] .

Answer: A

Step-by-step explanation: Because there 3 data points in each quartile which are lower quartile, median, and upper quartile to form four groups in the dataset.

Choice B is not correct because you don't know how many people have no pets. Choice C is not correct because it is exactly 75% of people own one or more pets. Choice D is not correct because 3/4 have between 1 and 6 pets not 1/2.

Hope it helps :)

Answer:

20 times

Step-by-step explanation:

This is calculated as:

The number of coal China consumes ÷ The number of coal Japan consumes

The number of coal China consumes =4 × 10⁹

The number of coal Japan consumes

= 2 × 10⁸

4 × 10⁹/2 × 10⁸

= 20 times

Answer:

6.4  cones full of water

Step-by-step explanation:

Given data

Radius of cone= 6inches

Slant height= 10 inches

Volume of cone= 1/3πr^2h

V= 1/3*3.142*6^2*10

V=  1/3*3.142*36*10

V=  1/3*1131.12

V= 377.04 cubic inches

Radius of right cylinder= 8 inches

Height= 12 inches

Volume of cylinder= πr^2h

Volume= 3.142*8^2*12

Volume= 3.142*64*12

Volume=2413.056 cubic inches

Hence the number of cone full of water needed to fill the cylinder is

=Volume of cylinder/volume of cone

=2413.056/377.04

=6.4  cones full of water
