Answer:

Step-by-step explanation:

 *   *    *

let the middle digit is a letter.

as first and second letters are same so consider them as one letter.

It can be filled in 26 ways.

third place is filled in 10 ways (0,1,2,3,4,5,6,7,8,9)

total number of ways=26×10=260 ways

again consider second place is a digit.

so consider second and third place as one digit.

it can be filled in ways=10

first place can be filled in ways=26

Hence number of ways=26×10=260

so total number of ways=260+260=520

Answer:  slope = [tex]\frac{6}{4}[/tex]

Step-by-step explanation:

To find the slope, choose two points. (0,0) and (4,6)

slope = (y2 - y1) / (x2 - x1) = (6 - 0) / (4 - 0) = 6 / 4

Answer:

[tex]x[/tex] intercept is at (6, 0).

[tex]y[/tex] intercept is at (0, 2).

Step-by-step explanation:

Given the equation of graph:

[tex]3x+9y=18[/tex]

To find:

[tex]x[/tex] and [tex]y[/tex] intercepts of the graph and then plotting the graph.

Solution:

[tex]x[/tex] intercept is the point on graph where the value of [tex]y[/tex] coordinate is zero.

[tex]y[/tex] intercept is the point on graph where the value of [tex]x[/tex] coordinate is zero.

Putting [tex]y=0[/tex] :

[tex]3x=18\\\Rightarrow x = 6[/tex]

So, [tex]x[/tex] intercept is at (6, 0).

Putting [tex]x=0[/tex] :

[tex]9y=18\\\Rightarrow y = 2[/tex]

So, [tex]y[/tex] intercept is at (0, 2).

Plotting the points of [tex]x[/tex] and [tex]y[/tex] intercepts on the graph and joining them to form the graph of given equation.

Answer:

800x40=32000

Step-by-step explanation:

Basically its 800 40 times.

Answer:

32,000

Step-by-step explanation:

First put 800 over 40

Second, multiply the 3rd zero by the first zero of 40

Multiply the 2nd zero by the same zero of 40

Multiply 8 by 4 and the result should be 800

Then you multiply 800 by 4.

0 x 4 is 0

0 x 4 is 0

8 x 4 is 32

(Make sure you add the zero from 40)

Put it together and you get 32,000

Answer:

[tex](0,-3)[/tex]

[tex](5,0)[/tex]

[tex](10,3)[/tex]

[tex](20,9)[/tex]

Step-by-step explanation:

Given

[tex]3x - 5y = 15[/tex]

Required

Form 4 pairs of (x,y) values

This question will be answered based on assumptions of x and y values;

Haven said that:

For point 1

Take x = 0

Substitute 0 for x in [tex]3x - 5y = 15[/tex]

[tex]3(0) -5y = 15[/tex]

[tex]-5y = 15[/tex]

Solve for y

[tex]y = 15/-5[/tex]

[tex]y = -3[/tex]

So; the first pair is:

[tex](0,-3)[/tex]

For point 2:

Take y = 0

Substitute 0 for y in [tex]3x - 5y = 15[/tex]

[tex]3x - 5(0) = 15[/tex]

[tex]3x = 15[/tex]

Solve for x

[tex]x = 15/3[/tex]

[tex]x = 5[/tex]

So, the pair is

[tex](5,0)[/tex]

For point 3:

Take x = 10

Substitute 10 for x in [tex]3x - 5y = 15[/tex]

[tex]3(10) - 5y = 15[/tex]

[tex]30 - 5y = 15[/tex]

Collect Like Terms

[tex]-5y = 15 - 30[/tex]

[tex]-5y = -15[/tex]

Solve for y

[tex]y = -15/-5[/tex]

[tex]y = 3[/tex]

So, the pair is:

[tex](10,3)[/tex]

For point 4:

Take y = 9

Substitute 9 for y in [tex]3x - 5y = 15[/tex]

[tex]3x - 5(9) = 15[/tex]

[tex]3x - 45 = 15[/tex]

Collect Like Terms

[tex]3x = 45 + 15[/tex]

[tex]3x = 60[/tex]

Solve for x

[tex]x = 60/3[/tex]

[tex]x = 20[/tex]

So, the pair is:

[tex](20,9)[/tex]

Step-by-step explanation:

i got a A on my TGA

the answer is 15cm (pls mark brainlest)

Answer:

3:40

Step-by-step explanation:

We need both measurements in the same units.

1 m = 100 cm

2 m = 2 × 1 m = 2 × 100 cm = 200 cm

15 cm to 2 m = 15 cm to 200 m

Divide both numbers in the ratio by 5 cm.

15 cm to 200 cm = 3:40

Answer:

[tex]\mathsf{y=-\dfrac13x+5}[/tex]

Step-by-step explanation:

Slope-intercept form of a linear equation:  [tex]\mathsf{y=mx+b}[/tex]

(where m is the slope and b is the y-intercept)

From inspection of the graph, the y-intercept is at (0, 5)

Therefore, b = 5

Choose another point on the line, e.g. (3, 4)

Now use the slope formula to find the slope:

[tex]\mathsf{slope=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]

where:

[tex]\implies \mathsf{slope=\dfrac{5-4}{0-3}=-\dfrac13}[/tex]

Therefore, the equation of the line is:

[tex]\mathsf{y=-\dfrac13x+5}[/tex]

Answer:

[tex]y=-\frac{1}{3} + 5[/tex]

Answer:

x = 8.75

Step-by-step explanation:

The given angles are corresponding and congruent, thus

8x - 25 = 4x + 10 ( subtract 4x from both sides )

4x - 25 = 10 ( add 25 to both sides )

4x = 35 ( divide both sides by 4 )

x = 8.75

Step-by-step explanation:

Using the given equation the rock will fall 16*(2)^2

= 16 * 4

= 64 feet in 2 seconds.

Therefore the rock will not hit the water in 2 seconds.

Answer: 104 ft²

Step-by-step explanation:

To find the area of the figure, we can find the area of the rectangle and the triangle. After that, we add the two areas together.

Rectangle

A=bh

A=10×8           [multiply]

A=80

----------------------------------------------------------------------------------------------------------------

Triangle

A=bh/2

A=6×8/2         [multiply]

A=48/2           [divide]

A=24

Now that we have the areas, we can add them together.

A=80+24        [add]

A=104 ft²

Now, we know that the area is 104 ft².

We will see that the change in momentum is P' - P = -17.6 kg*m/s, and the percentage of kinetic energy lost is 30.56%.

The momentum is given by the product between the mass and the speed.

So the original momentum is:

P = 0.32kg*30m/s = 9.6 kg*m/s

After the bounce, the new velocity is -25m/s, then the new momentum is:

P' = 0.32kg*-25 m/s = -8 kg*m/s

The change in momentum is:

P' - P = -8 kg*m/s - 9.6 kg*m/s = -17.6 kg*m/s

The kinetic energy is:

KE = (1/2)*M*v^2

The initial kinetic energy is:

KE = (1/2)*0.32kg*(30 m/s)^2 = 144 J

The final kinetic energy is:

KE =  (1/2)*0.32kg*(-25 m/s)^2 = 100 J

The percentage lost is:

P = 100%*(144 J - 100J)/(144 J) = 30.56%
