Will be marked brainliest and get ! if a machine produces 280 appliances per hour, the total number of appliances produced in x hours can be represented as a function f(x)=280x. a )how many appliances can be produced in 3.5 hours? b)how many more appliances can be produced in 7h than in 4.25h answer both questions!

a) For this first part, all we need to do is "plug in" 3.5 for , which gives us a value of .

b) For this second part, we will find the number of appliances produced in 7 hours and then subtract the number of appliances produced in 4.25 hours:

Our answers are a) 840 and b) 770.

what is the original number? you forgot to add it.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

happy to
