506 x - 92 y + 90 = 498 - 4 x + 6 y

Geometric figure:

line

y = (255 x)/49 - 204/49

510 x - 98 y - 408 = 0

506 x - 92 y + 90 = 6 (y + 83) - 4 x

Real solution:

y = (255 x)/49 - 204/49

Solution:

y = (255 x)/49 - 204/49

Integer solution:

x = 49 n + 40, y = 255 n + 204, n element Z

Solution for the variable y:

y = 51/49 (5 x - 4)

Answer:

Step-by-step explanation:

Lets take 4905 and 802

Firstly to figure out which of these two numbers is bigger we first look at the highest place value that either one of these two numbers have

In this case its 4 in the thousands place in the number 4905

Next we look at which number 802 has in the thousands place

In this case there is no number or 0

4 is bigger than 0 so we know that 4905 is bigger than 802

Lets take another example

4905 and 8204

Here both numbers have a number in the thousands place on is 8 and the other is 4

8 is bigger than 4 so 8204 must be larger

I'm just saying comparing integers should come very easily and you really don't need to think much to figure this out

I'm guessing you mean how do you compare numbers which are non-integers like 4/6 or  4/5  and this is quite easy

There are multiple ways but one method is to just multiply the denominator of one fraction with the numerator of the other and do the same for the other fraction

lets take 4/6 and 4/5

4*5=20

and 4*6= 24

4/6 we can assign 20

and 4/5 is 24

the bigger number is 24 so 4/5 is bigger

Step-by-step explanation:

Answer:

35.34 and 16.66

Step-by-step explanation:

Given data

let the numbers be x and y

the smaller number = x

the larger number = y

x+y=52--------1

The larger number is 2 less than twice the smaller number

y=2x-2-------2

put y= 2x-2 in eqn 1

x+2x-2=52

3x-2=52

3x=52-2

3x=50

x= 50/3

x= 16.66

put x=16.66 in eqn 1 to find y

x+y=52

16.66+y= 52

y=52-16.66

y= 35.34

Hence the numbers are

35.34 and 16.66

Check

35.34+16.66= 52

Answer:

Options B and E.

Step-by-step explanation:

We want to see for which systems the point (-3, 2) is a solution (a solution of a system means that both equations intersect in that point).

The point (-3, 2) is a solution of the system only if this point belongs to both linear equations in the system.

Then for each system, we need to replace x by -3 and y by 2 in both equations and see if the equality is true or not.

A)

6x - y = 15

-3x + 4y = -18

In the first equation we have:

6*(-3) - (2) = 15

-18 - 2 = 15

-20 = 15

This is false, so we can discard option A.

B)

2x + y = -4

3x + 2y = -5

In the first equation we have:

2*(-3) + 2 = -4

-6 + 2 = -4

-4 = - 4  

This is true, now let's look at the other equation.

3*(-3) + 2*(2) = -5

-9 + 4 = -5

-5 = - 5

This is also true, then the point (-3, 2) is a solution for both equations, then the point (-3, 2) is a solution for the system.

C)

x + 8y = 19

4x - 5y = 2

In the first equation we have:

(-3) + 8*(2) = 19

-3 + 16 = 19

13 = 19

This is false, then we can discard option C.

D)

8x + y = 22

-2x - 5y=4

In the first option we have:

8*(-3) + 2 = 22

-24 + 2 = 22

-22 = 22

This is false, so we can discard option D.

E)

5x - y = -17

x + 4y = 5

In the first option we have:

5*(-3) - (2) = -17

-15 - 2 = -17

-17 = -17

This is true, now let's look at the other equation:

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

-3 + 8 = 5

5 = 5

This is also true, then the point (-3, 2) is a solution for both equations in the system, which means that the point (-3, 2) is a solution for the system.

Then the correct options are B and E.

Answer:

396 in.^2

Step-by-step explanation:

The cushion is shaped like a cylinder with 14 inch diameter and 2 inch height.

We need to find the surface area of the cylinder.

diameter = 14 in.

radius = diameter/2 = 7 in.

height = 2 in.

A = 2(pi)r^2 + 2(pi)rh

A = 2(3.14159)(7 in.)^2 + 2(3.14159)(7 in.)(2 in.)

A = 395.84 in.^2

A = 396 in.^2

The amount of fabric that Maggie will need for manufacturing the cushion is 395.84 sq. inches.

Supposing that a considered cylinder has radius of 'r' units and height 'h' units, then the surface area of that cylinder would be:

[tex]S = \pi r^2 + \pi r^2 + 2\pi r h = 2\pi r(r + h) \: \rm unit^2[/tex]

The table's diameter is of 14 inches. That means, its radius is of 14/2 = 7 inches.

The cushion is going to have 2 inches extra from all sides, so approximately, it is going to be like a cylinder with radius 7 inches and height 2 inches.

The fabric needed for making cushion (from outer side only) in terms of area is same as the surface area of cylinder with radius of 7 inches and height of 2 inches.

Thus, the amount of fabric that Maggie will need for manufacturing the cushion is [tex]S = 2\pi r(r + h) = 2\pi \times 7(7 + 2) \approx 395.84 \: \rm in^2[/tex]

Answer:

817.71

Step-by-step explanation:

Hi!

This involves applying trigonometry.

Because we are trying to figure out the height of Burj Khalifa, we are trying to find the length of AB. We already have CB, which is the adjacent side with respect to the angle. Then, AB would be the opposite side with respect to the angle given.

Remember SOH CAH TOA? Well, we have the adjacent and opposite sides involved in this, so we use the tangent function!

It will be as follows:

tan(73) = AB / 250

AB = (250)(tan(73))

AB = 817.71 meters
