Jason wants to add a fence to his yard to make it the shape of a rectangle. What is the measure of angle MKJ in the portion of the yard not inside the fence?

Answers

Answer:

[tex]\angle MKJ = 34[/tex]

Step-by-step explanation:

Given

[tex]\angle LKJ = 124[/tex]

Required

Find [tex]\angle MKJ[/tex]

From the attachment:

The measure of [tex]\angle MKJ[/tex] is calculated using the following expression:

[tex]\angle MKJ + \angle LKM = \angle LKJ[/tex]

Where

[tex]\angle LKM = 90[/tex] -- right-angled.

The expression becomes

[tex]\angle MKJ + 90 = 124[/tex]

[tex]\angle MKJ = 124 - 90[/tex]

[tex]\angle MKJ = 34[/tex]

Find the area of all the shapes and then add them together I believe...

Answer:

468 Square Centimeters

Step-by-step explanation:

Surface area can be calculated by adding the areas of each face on a prism:

The rectangle to the left is a 9 by 10. The formula for the area of a rectangle is length times width, so we can get the area by multiplying 9 and 10: 9*10=90To the right of that rectangle is another rectangle. This time it's a 10 by 12, as we can see in the picture. Multiply 10 and 12: 10*12=120The last rectangle, on the right, is a 15 by 10. Multiply 15 and 10: 15*10=150Now look at the triangle on the top. The formula for the area of a triangle is base times height divided by 2. The base of the triangle in this case is the bottom side, 12. The height is how tall the triangle is, 9. Multiply 9 and 12: 9*12=108. Divide that by 2: 108/2=54Finally, look at the triangle on the bottom. It is exactly the same as the one on the top, with a base of 12 and a height of 9. Since it is exactly the same, we know that it has the same area too: 54Add up the areas: 90+120+150+54+54=468

please let me know if the answer or explanation is incorrect, hope this helps :)

Find the distance between (5, 9) & (-7, -7). Round to the nearest tenth.

Answers

Distance equals end minus start

(-7,-7)-(5,9)=
(-7-5,-7-9)=(-12,-16)

(-12,-16) gives us the distance point coordinates. Now to find the magnitude we can take sqrt((-12)^2+(-16)^2)=20

So the distance between the two points is 20

Frank wants to know how many people live in each household in his town. He conducts a random survey of 10 people and asks how many people live in their household. His results are shown in the table.

1 6 2 4 4 3 5 5 2 8

Calculate the MAD of the number of people per household.

Answers

Answer:

1.6

Step-by-step explanation:

The average of this ten number is (1+6+2+4+4+3+5+5+2+8)/10=4

So the MAD is (|1-4|+|6-4|+|2-4|+|4-4|+|4-4|+|3-4|+|5-4|+|5-4|+|2-4|+|8-4|)/10

=(3+2+2+0+0+1+1+1+2+4)/10

=1.6

Answer:

15.05 miles

2 :09:12

5 hours 19 minutes 18 seconds

Step-by-step explanation:

Given :

28/4/18:

Time : 1 :03 : 25

Fastest mile = 02 : 25

Distance = 15.05 miles

03/5/18:

Time : 2:06: 41

Fastest mile = 02 : 53

Distance = 28.70 miles

08/5/18:

Time : 2 :09:12

Fastest mile = 02 : 45

Distance = 26.39 miles2

1.) shortest distance cycled :

From the data:

15.05 < 26.39 < 28.70

Shortest distance cycled = 15.05 miles

The longest the cycled:

1 :03 : 25 < 2:06: 41 < 2 :09:12

Longest = 2 :09:12

Total cycling time :

1 :03 : 25 + 2:06: 41 + 2 :09:12

(1 + 2 + 2)= 5 hrs

(03 + 06+ 09) = 18 minutes

(25 + 41 + 12) = 78 seconds = 1 minute 18 seconds

18 minutes + 1 minute = 19 minutes

Total = 5 hours 19 minutes 18 seconds

Look at thee isosceles triangle what angle is B?
(I am so so tired is 2 in the morning)

Answers

Isosceles means the bottom right angle is also 65, so to add up to 180, the final angle (B) must be 50.

Answer:

m∡b = 50°

Step-by-step explanation:

this is an isosceles triangle so the other base angle also measures 65°

there are 180° in a triangle so m∡b = 180-(65+65) or 50°
