Jennifer is wrapping presents. one of the rectangular gift boxes has dimensions 1 in. • 7 in. • 3 in. and the other has dimensions 2 in. • 7 in. • 9 in. how much wrapping paper will she need to wrap both gifts in total? explain; )

Total amount of wrapping required = 252 inch²

Step-by-step explanation:

Dimensions of the 1st box are given by,

Length = 1 inch, Width = 7 inch and Height = 3 inch

As, Surface area of a rectangular box =

So, Surface area of the 1st box =

i.e. Surface area of the 1st box =

i.e. Surface area of the 1st box = 2 × 31 = 62 inch²

Further, we have,

Dimensions of the 2nd box are given by,

Length = 2 inch, Width = 7 inch and Height = 9 inch

So, Surface area of the 2nd box =

i.e. Surface area of the 2nd box =

i.e. Surface area of the 2nd box = 2 × 95 = 190 inch²

Thus, the total amount of wrapping required = 62 + 190 = 252 inch².

she would want to sell 10 full-year subscriptions and at least 9 half-year subscriptions to get a total of at least $300. 

i hope this answer you! if you have any further questions or concerns, feel free to ask! : )

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
