Answer:

[tex]1350000m = 135000000cm[/tex]

Step-by-step explanation:

Given

[tex]Radius = 1,350,000m[/tex]

Required

Convert to centimetres

In standard unit of conversion

[tex]1m = 100cm[/tex]

Multiply both sides by 1350000

[tex]1350000 * 1m = 1350000 * 100cm[/tex]

[tex]1350000m = 135000000cm[/tex]

===========================================================

Explanation:

The x coordinate of point C is x = 7

The x coordinate of point D is x =  -1

Add up these x coordinates to get 7+(-1) = 6

Then cut that result in half: 6/2 = 3

The x coordinate of the midpoint is 3

The y coordinate of the midpoint is found in a similar fashion. You should find the midpoint is located at (3, -3.5) which is the same as saying (3, -7/2) since -7/2 = -3.5

Answer:

Neither

Step-by-step explanation:

In this question, we have to verify if the equations are parallel, perpendicular, or neither to each other.

Turn the first equation into slope-intercept form so we can get a better understanding:

4x - 3y = 9

Subtract 4x from both sides.

-3y = -4x + 9

Divide both sides by -3.

y = 4/3x - 3

Now lets compare both lines:

y = 4/3x - 3

y = 3/4x + 7

Since the slopes have to be the same in order for the lines to be parallel, we can see that the lines are NOT parallel.

We also know that in order for the lines to be perpendicular, one has to be positive and the other has to be negative. In this case, they both are positive. This means that the lines are NOT perpendicular.

This means that our answer would be neither.

Answer:

The coordinates of the image triangle will be:

Please also check the attached figure.

The green triangle represents the image triangle.

Step-by-step explanation:

We know that when we reflect a point across the y-axis, the y-coordinate remains the same but the x-coordinate reveres its sign.

Thus,

The rule of reflection of the point P(x, y) across the y-axis is:

P(x, y) → P'(-x, y)

In the attached figure, let the coordinates of the triangle are:

Using the rule of reflection across the y-axis:

P(x, y) → P'(-x, y)

Thus, the coordinates of the image triangle will be:

A(1, 1) → A'(-1, 1)

B(1, 3) → B'(-1, 3)

C(3, 3) → C'(-3, 3)

Therefore, the coordinates of the image triangle will be:

Please also check the attached figure.

The green triangle represents the image triangle.

Answer:

y = 42°

Step-by-step explanation:

The third vertex in the triangle with y is adjacent to a right angle, thus is right.

The sum of the 3 angles in a triangle = 180°, then

y = 180° - (90 + 48)° = 180° - 138° = 42°

Answer:

Car A's speed is 75 miles per hour

Step-by-step explanation:

As the distance-time graph represents the straight line. Thus, the slope of any line would remain constant along the line.

We also know that in a distance-time graph, the slope of the line would be equal to the speed of the object.

Taking two points from the graph

Determining the slope

Slope = [y₂-y₁] / [x₂-x₁]

          = [100 - 25] / [1 - 0]

          = 75 / 1

           = 75 miles per hour

Therefore, Car A's speed is 75 miles per hour

Answer:

She will save [tex]\$24.44[/tex] by driving.

Step-by-step explanation:

Given: Jocelyn lives in Granite Falls. She wants to visit Megan in Spokane Valley. She can fly from Seattle to Spokane for [tex]\$96.20[/tex] round trip or she can drive a total of [tex]650[/tex] miles round trip. If her car gets [tex]25[/tex] miles per gallon, and gas costs [tex]\$2.76[/tex]/gallon.

To find: how much money will she save by driving?

Solution:

The total cost for flying Seattle to Spokane is [tex]\$96.20[/tex].

Now, in order to find how much money will she save by driving, we need to first find the total cost for driving a total of [tex]650[/tex] miles round trip.

So, total distance [tex]=650[/tex] miles.

Car covers [tex]25[/tex] miles per gallon.

So, to cover [tex]650[/tex] miles, [tex]\frac{650}{25} =26[/tex] gallons of gas is required.

Now, gas costs [tex]\$2.76[/tex]/gallon.

Therefore, total charge [tex]=26\times2.76=\$71.76[/tex].

So, total money saved[tex]=\$96.20-\$71.76=\$24.44[/tex]

Hence, she will save [tex]\$24.44[/tex] by driving.

Answer:$22.50

Step-by-step explanation: you save $7.50

Sale price of shoes = $22.5

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, we have to divide the given number by the whole number and multiply by 100.

Given,

Cost of shoes = $30

Discount on shoes = 25%

Discount = (25/100) × 30

Discount = 750/100

Discount = $7.5

Sale price = Cost - discount

Sale price = $30 - $7.5

Sale price = $22.5

Hence, $22.5 is the sale price of shoes.

A quadratic equation is an algebraic expression in the form of variables and constants.

A quadratic equation has two roots as its degree is two.

Given, x² + 6x = - 6.

We know in ax² + bx + c = 0, x = ± √(b² - ac)/2a.

∴ x² + 6x + 6 = 0.

Answer:

It is $25 per hour

Step-by-step explanation:

Answer is A

Answer: $25 per hour.

Step-by-step explanation: The waiter earned $250 in 10 hours. 250/10 = $25 per hour.

The area of the first figure is 629.86 sq. meters and for the second figure, the combined area would be 430.18 629.86 sq. meters.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

For the first figure, we need to find the area of the semicircles and the area of the rectangle, then we get the combined area that gives the area of the figure.

The length of the rectangle is 28m. we can see that the diameter of the semicircle is equal to half of the length of the rectangle.

So. D = 14m and radius = 7m

The area of the 2 semicircles = [tex]\pi r^2[/tex]

                                              = π x 7 x 7

                                             = 49π sq. meter

The breadth of the rectangle = 24 - r

                                                 = 24 - 7

                                                 = 17m

The area of the rectangle = length × Width

                                           = 28 x 17

                                           = 476 sq. meter

The combined area = 629.86 sq. meter

B. The area of the 2 semicircles = [tex]\pi R^2[/tex] + [tex]\pi r^2[/tex]

                                                      = π ( 11 x 11 + 4 x 4)

                                                      = 3.14 x (121 + 16)

                                                      = 430.18 sq. meter

Step-by-step explanation:

Ok.....Since I can't graph it, we can make a table

x       y

3       9

1        1

From 9 to 1, you subtract 8 (this is for the y section)

From 3 to 1, you subtract 2 (this is for the x section)

Now all you have to do is divide the y with the x

y/x = 8/2 = 4

And 4 will be your slope for these two points.
