40 times 30 equals whatttttttt

Answer:

y=1

x=3

Step-by-step explanation:

Multiply 2x by three because if you substitute to y, you would have the multiply.

Write what is left. 6y+4y=10

Combine like terms   10y=10

y=1

x=3

Check      3=3(1)

                     6+4=10

So this solution is correct

Angle D and angle B are congruent because they are corresponding angles. Angle E and C are also congruent because they are corresponding angles.

Halfway Between 0 and 121

Halfway Between

When you ask "What number is halfway between 0 and 121?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=0 and Y=121.

Halfway Between Line

To find the number halfway between 0 and 121, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 0 and 121 into our formula, we get:

(0 + 121)/2 = 60.5

Thus, the number halfway between 0 and 121 is 60.5

Answer:

solution given;

half way between 0 and 121=?

let a=0

and

b=121

we have

halfway =[a+b]/2=[0+121]/2=60.5

half way between 0 and 121 is 60.5

Answer:

The answer is

[tex] a = \frac{11}{7} \\ b = \frac{6}{7} [/tex]

Step-by-step explanation:

[tex] \frac{3 + \sqrt{2} }{3 - \sqrt{2} } \times \frac{3 + \sqrt{2} }{3 + \sqrt{2} } \\ = \frac{9 + 3 \sqrt{2} + 3 \sqrt{2} + 2}{9 - 3 \sqrt{2} + 3 \sqrt{2} - 2 } \\ = \frac{11 + 6 \sqrt{2} }{7} \\ = \frac{11}{7} + \frac{6}{7} \sqrt{2} \ [/tex]

In comparison

Then

[tex]a = \frac{11}{7} \\ b = \frac{6}{7} [/tex]

Answer:

x = 0, y = 2

Step-by-step explanation:

Substitute the first equation into the second equation so 3x + 3(x+2) = 6. Simplify this to get x = 0. Plug x = 0 back into the first equation to get y = 2.

Answer:

x = 0, y = 2

Step-by-step explanation:

y = x + 2

3x + 3y = 6

3x + 3(x + 2) =6

3x + 3x +6 = 6

6x = 0

x = 0

y = x + 2 = 0 + 2 = 2

The sequence is arithmetic

Step-by-step explanation:

Here we want to determine the sequence is arithmetic

If the sequence was arithmetic, the difference between the terms would be constant

We have this as;

10-(-12) = 22

32-10 = 22

54-32 = 22

As we can see, the difference is constant and so we have it that the sequence is arithmetic

Answer:

Yo, thx for the free points man

Step-by-step explanation:

Answer:

x = 12

Step-by-step explanation:

x = length of side of square A

'x-3' represents length of side of square B

Perimeter of square A = 4x

Perimeter of square A = 4x - 12

we can set up the following proportion based on ratio of 4:3

4x / 4 = 4x - 12 / 3

cross-multiply:

4(3x) = 4(4x-12)

12x = 16x - 48

-4x = -48

x = 12

Step-by-step explanation:

Answer:

We conclude that, at 4 minutes, both will have the same height which is 200 feet.

Step-by-step explanation:

Given the system of equations

[tex]y=400+50x[/tex]

[tex]y=300+25x[/tex]

Important Tip:

Graphing the system of equations

The graph of the equation y = 400 + 50x

First, determine the y-intercept of the equation y = 400 + 50x by substituting x = 0

[tex]y = 400 + 50x[/tex]

[tex]y = 400 + 50(0)[/tex]

[tex]y = 400 + 0[/tex]

[tex]y = 400[/tex]

Thus, we determine that the ordered pair (0, 400) represents the y-intercept of the equation y = 400 + 50x.

Next, determine the x-intercept of the graph of the equation y = 400 + 50x by substituting y = 0

[tex]y = 400 + 50x[/tex]

[tex]0=400+50x[/tex]

switch sides

[tex]400+50x=0[/tex]

Subtract 400 from both sides

[tex]400+50x-400=0-400[/tex]

Simplify

[tex]50x=-400[/tex]

Divide both sides by 50

[tex]\frac{50x}{50}=\frac{-400}{50}[/tex]

Simplify

[tex]x=-8[/tex]

Thus, we determine that the ordered pair (-8, 0) represents the x-intercept of the equation y = 400 + 50x.

Important Tip:

The red graph on the diagram represents the equation y = 400 + 50x having the y-intercept (0, 400) and x-intercept (-8, 0)

Please check the attached diagram.

The graph of the equation y = 300 + 25x

Now, determine the y-intercept of the equation y = 300 + 25x by substituting x = 0

[tex]y = 300 + 25x[/tex]

[tex]y = 300 + 25(0)[/tex]

[tex]y = 300 + 0[/tex]

[tex]y = 300[/tex]

Thus, we determine that the ordered pair (0, 300) represents the y-intercept of the equation y = 300 + 25x.

Next, determine the x-intercept of the graph of the equation y = 300 + 25x by substituting y = 0

[tex]y=300+25x[/tex]

[tex]0 = 300 + 25x[/tex]

switch sides

[tex]300+25x=0[/tex]

Subtract 300 from both sides

[tex]300+25x-300=0-300[/tex]

Simplify

[tex]25x=-300[/tex]

Divide both sides by 25

[tex]\frac{25x}{25}=\frac{-300}{25}[/tex]

Simplify

[tex]x=-12[/tex]

Thus, we determine that the ordered pair (-12, 0) represents the x-intercept of the equation y = 300 + 25x.

The blue graph on the diagram represents the equation y = 300 + 25x having the y-intercept (0, 300) and x-intercept (-12, 0)

Please check the attached diagram.

Analyze the POINT OF INTERSECTION:

As we already know that the point of intersection of the two lines would give us the point at which both have the same height.

The diagram indicates that:

at x = -4, the value of y = 200.

It is the point where both lines meet.

Thus, the point of intersection of the two lines is:

(x, y) = (-4, 200)

Conclusion:

As x represents the time in minutes and y represents the height in feet.

Thus, we conclude that at x = 4 minutes, both will have the same height i.e. y = 200 feet

Therefore, we conclude that, at 4 minutes, both will have the same height which is 200 feet.

Answer:

Inside the circle, a distance of [tex]\sqrt{34}[/tex] from the center of the circle.

Step-by-step explanation:

Center of circle is at (0,0)

One point of the circle is at (0,[tex]\sqrt{38}[/tex])

Since the only known point is in the y-axis, the radius of the circle must be [tex]\sqrt{38}[/tex].

[tex]\sqrt{38}[/tex] = 6.164

So the point (-5,-3) is still inside the circle as the distance from point (-5,-3) to the center of the circle is [tex]\sqrt{(5)^2+(-3)^2}[/tex] or [tex]\sqrt{34}[/tex] which is less than the radius of the circle.

Point N(-5, -3) lies inside the circle.

We have,

To determine the location of point N(-5, -3) in relation to the given circle centered at C(0, 0), we can calculate the distance between point C and point N.

- If the distance is equal to the radius of the circle, then N lies on the circle.

- If the distance is greater than the radius, N lies outside the circle.

- If it is smaller, N lies inside the circle.

Let's calculate the distance between C(0, 0) and N(-5, -3):

Distance = √[(x2 - x1)² + (y2 - y1)²]

= √[(-5 - 0)² + (-3 - 0)²]

= √[25 + 9]

= √34

Since the distance (√34) is less than the radius of the circle, which is √38 (distance between C and M), we can conclude that the point N(-5, -3) lies inside the circle centered at C(0, 0).

Thus,

Point N(-5, -3) lies inside the circle.
