The table shows the battery life of four different mobile phones:

Mobile Phone Battery Life
Phone Battery Life (hours)
A 20
B 25
C 10
D 18

If 8.45% of the battery life of each mobile phone is used in a day by a typical user, for which mobile phone is 2.1 hours of battery life used in a day? (1 point)

Phone A

Phone B

Phone C

Phone D

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
