Answer:

First one is 41

Second one is 87

Step-by-step explanation:

Make the shaded part as a trapezoid which is (3+6)*10/2 you just have to get rid of 2*2. So you get 41 as the answer.

The unshaded part will be 16*8 then subtracts the shaded part which is 41. Then you get the answer 87.

Insert three arithmetic means between 25 and 9

Aleonysh [2.5K]

Answer:

21, 17, 13

Step-by-step explanation:

Find the mean of the 2 given values

mean = $\frac{25+9}{2}$ = $\frac{34}{2}$ = 17

Noe find the mean of 25 and 17 and 17 and 9

mean = $\frac{25+17}{2}$ = $\frac{42}{2}$ = 21 and

mean = $\frac{17+9}{2}$ = $\frac{26}{2}$ = 13

Thus the 3 means are 21, 17 and 13, that is

25, 21, 17, 13, 9

Mars2501 [29]

To get this we divide the total miles she ran for the weeks by the no of weeks she ran.

Total miles =5.5 +7.25+10= 22.25 miles altogether.

no of weeks =3.

Average miles = 22.75 /3=7.583333≅7.58(nearest hundredth)
