Question

Let me know if you can answer these :)

Answer 1

10. 285

11.
`6(3)/(4)`

16.a. Stiles Family

Reason-The Styles family uses twice as much as the other two, because the electric consumption per person (which is =745 KWh) is much higher than the other two.

16.b. Mendelez family

Reason-The Mendelez family uses the least amount of water, because the water usage per person (which is =875 gallons) is much lower than the other two.

Explanation:

10. In 6 mins, no. of machine parts produced = 114

in 1 min, no. of machine parts produced = 114/6

in 15 min, no. of machine parts produces
`(114 *15)/(6)\\=285`

11. To make 8 jumbo muffins take, amount of baking powder used =
`1(1)/(2) =(3)/(2)`

To make 1 jumbo muffin, amount of baking powder used =
`(3)/(2) / 8` =3/16

To make 3 dozens = (3 * 12 )= 36 muffins, amount of baking powder used = 36 *3/16

`=(27)/(4)` =
`6(3)/(4)`

-------------------------------------------------------------------------------------------------------------

16. a. Electricity consumed by 1 person in the Mendelez family :

=1560/4

=390 KWh

Electricity consumed by 1 person in the Barton family:

=2130/6

=355 KWh

Electricity consumed by 1 person in the Styles Family:

=1490/2

=745 KWh

The Styles family uses twice as much as the other two, because the electric consumption by 1 person is much higher than the other two.

16.b. Water consumed by 1 person in the Mendelez family = 3500/4=875 gallons

Water consumed by 1 person in the Barton family = 6400/6=1050 gallons

Water consumed by 1 person in the Styles family =2500/2=1250 gallons
