Answer:

8. 15

10. 90

12. 36

Step-by-step explanation:

8.

The mean of the 5 data is 51.

(55 + 60 + 35 + 90 + x) ÷5 = 51

(240 + x) ÷5 = 51

240 + x = 255

x = 15

10.

The mean of the 5 data is 127.

(100 + 112 + 98 + 235 + x) ÷5 = 127

(545 + x) ÷5 = 127

545 + x = 635

x = 90

12.

The mean of the 5 data is 40.

(34 + 56 + 45 + 29 + x) ÷5 = 40

(164 + x) ÷5 = 40

164 + x = 200

x = 36

A pole that is 3.1 m tall casts a shadow that is 1.35 m long at the same time a nearby building casts a window that is 37.75 m l
Veronika [31]
Okay so you have to set it up as 3.1 over 1.35 and 37.75 over x then you solve for that by doing 37.75 times 1.35 which is 50.9625 and then divide by 3.1 and you get 16.4
