Answer:

4. 480.38m² 6. 3.35

Step-by-step explanation:

Assuming you're looking for the area of the shaded region, you must first be aware that the entire circle has a 360 angle.

From there. for no. 4:

You subtract 87 from 360 to find the angle of the major arc.

360-87=273

From there you must also know the formula to find the area of a sector which is:

(x/360)×pi×r²

In our case 273 is x and 14.2 is r so

(273/360)×pi×14.2²= 480.38

Do the same steps to find 6

Louann and Carla received equal scores on a test made up of multiple choice questions and an essay. Louann got 14 multiple choic

Gnoma [55]

Louann= 14x+24
Carla= 16x+14
So basically this is just like solving equations. The way I did this was just put random numbers for x and then solve it.
First attempt:
14(7)+24=16(7)+14
98+24=112+14
122=126
Okay the first one didn't work so I use 6 for x.
Second attempt:
14(6)+24=16(6)+14
84+24=96+14
108=110

So 6 didn't work and you already should know that the answers should be between 1 and 5.

So now I going to do 5 for x
Third attempt:
14(5)+24=16(5)+14
70+24=80=14
94=94

And so the answer is 5! :D The multiply choice questions were worth 5 points and Louann and Carla had 94 for their scores! I hope this help you out and clear for you! :D
