The number 3.4 can be classified as

a rational number

Step-by-step explanation:

3.4 is a terminating decimal. That means that after the 4 in 3.4 there are no other numbers (the number "ends" after the 4) Also, 3.4 can be written as a RATIO of two numbers (looks like a fraction)

3.4 = 3 4/10 = 3 2/5

= 15/5 + 2/5

= 17/5

If you put 17÷5 in a calculator it would say 3.4

3.4 = 17/5

3.4 is a rational number.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
