Answers

Answer:

22.28

Step-by-step explanation:

Since you know the diameter of the semi circle which is 4 because the shape is a parallelogram, you find the circumference of the circle and divide it by two because we only need to know wheat half of the circumference is. When you do this you end up with the answer 6.28. Then you add the lengths of the parallelogram to 6.28, disregarding the circumference of the circle which isn't part of the perimeter. Doing this is 6.28+6+4+6 which equals 22.28 units.

Answer:

Answer 21ab

Step-by-step explanation:

First you do 3 times 3a which you get 9a then to 3 times 4b and you get 12b. So 12b plus 9a equals 21ab

Answer:

9a+12b

Step-by-step explanation:

use the distributive property

since the three is on the outside of the parethesis distribute it

3x3a= 9a

then do the same with 4b

3x4b= 12b

final answer

9a+12b

Find the measure of ABC

Answers

Answer:

<ABC = 54 degrees

Step-by-step explanation:

Taking the sum of angle on the straight line ABD as 180 degrees

3x+9 + 9x - 9 =180

12x = 180

x = 180/12

x =  15 degrees

Since <ABC = 3x+9 (vertically opposite angles)

<ABC = 3(15)+9

<ABC = 45+9

<ABC = 54 degrees

Plot the image of quadrilateral ABCD under a reflection across line l.

Please answer!!!!

Answers

Answer:

Step-by-step explanation:

The coordinates of the reflection of a point (x, y), across the y-axis is the point (-x, y)

Please find attached the plot of the image of quadrilateral ABCD under a reflection of the line l

Method:

The coordinates of the vertices of the given quadrilateral ABCD are as follows

A(-2 0), B(-3, 4), C(0, 4), and D(-1, 1)

Due to its orientation, the line l can be taken as being equivalent to the y-axis

The coordinates of the image of (x, y) following a reflection across the y-axis is (-x, y)

Therefore, for the image of the quadrilateral ABCD following a reflection across the y-axis to give the quadrilateral A'B'C'D', the coordinates of A'B'C'D' are;

A(-2 0), reflected across the y-axis gives the image A'(2, 0)

B(-3, 4), reflected across the y-axis gives the image B'(3, 4)

C(0, 4), reflected across the y-axis gives the image C'(0, 4)

D(-1, 1), reflected across the y-axis gives the image D'(1, 1)

The coordinates with which the image of the of the quadrilateral ABCD can be plotted are therefore;

A'(2, 0), B'(3, 4), C'(0, 4), and D'(-1, 1)

The plot of the quadrilateral ABCD and the image A'B'C'D' can be created using MS Excel presented in the attached graph

Pablo is on a road trip which will cover a distance of 840 miles. He plans to break the trip up and will complete it over three days. The distances and average speeds for the first two days are shown below.Day One: 55 hours at an average speed of 66 miles per hour. Day Two: 55 hours at an average speed of 58 miles per hour. If the average speed on the third day is 55 miles per hour, how many more hours will it take for Pablo to complete his trip?

Answers

Answer: 2.87 hours

Step-by-step explanation:

There may be a typo in the question because 55 hours in a day is not logical so you must have meant 5.5 hours.

In that case, the hours he will require on the third day would require the distance left to calculate. Get this distance from the first 2 days.

Day 1 distance travelled = Time * Speed

= 5.5 * 66

= 363 miles

Day 2 distance travelled = Time * Speed

= 5.5 * 58

= 319 miles

Total distance remaining

:= 840 - 363 - 319

= 158 miles

Travelling at 55 miles per hour, the time to be taken is:

= Distance remaining / Speed

= 158 / 55

= 2.87 miles per hour
