Please Please Help Me In These Math Questions!!!!’
Harman [31]

Answer:

m∠JLN = 42°

m∠MLK = 90°

m∠KLO = 42°

m∠JLO = 138°

m∠AGE = 160°

Step-by-step explanation:

m∠JLN = 90-48=42°

m∠MLK = 90°

m∠KLO = 42° (∠KLO opposite of ∠JLN, Opposite angles are congruent)

m∠JLO = 180-42=138°

For the second question, things become somewhat more complex.

We know that ∠GHD = 2x° and ∠AGH (x+15)°.

You correctly calculated that x=15°.

∠AGE is equal to both 180-(x+15)° and 180-2x°. Either equation will work just fine.

∠AGE = 180 - (15 + 15) = 180 - 30 = 160°

So m∠AGE = 160°

8. Jaime has 20 min to get to her after- school job. Despite her best efforts, she is
7nadin3 [17]

The calculation of the mean shows that Jamie should not lose her job as she was faster after the talk from the boss.

<h3>How to calculate the mean?</h3>

The mean of the travel time in the first scenario will be:

= (18, 20, 22, 27, 16, 23, 25,26, 19, 28)/10

= 224/10

= 22.4

She she shows consistency, the mean will be:

= (22, 20, 22, 24, 24, 23, 25, 21, 19, 21)/10

= 221/10

= 22.1

Heather has a rectangular yard, she measures it and finds out it is 24 1/2 feet long by 12 4/5 feet wide. She wants to know how
Temka [501]

Answer: $2,446.08

Step-by-step explanation:

Lets convert the length and width into decimal form so it's easier to understand.

24 1/2= 24.5

12 4/5= 12.8

Now we must multiply to get the area. 24.5x12. 8= 313. 6 ft

Each square inch costs .65 so we must multiply .65 by 12 to see how much a foot costs. 12x0.65= 7.8

Now that we know how much each foot cost lets multiply 313.6 by 7.8. 313.6x 7.8= $2446.08
