Is the list 3,-5,-2.4,1 a whole number, interger or a rational number

We can define a whole number as "a positive numbers, including zero, without any decimal or fractional parts".

We can define an integer number as "a whole number that can be positive, negative, or zero".

Finally, a rational number is "any number that can be expressed as the quotient or fraction of two integers".

In our list:

3 is a whole number because it's positive and doesn't have any decimal or fractional part.

-5 is an integrer because is a negativewhole number.

-2.4 is a rational number because it can be written as -24/10.

1 is a whole number because it's positive and doesn't have any decimal or fractional part.

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.

step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
