A box has a length of 15 in., a width of 7 in., and a height of 9 in. If Tara plans to cover the box with wrapping paper, how much wrapping paper will she need?

Answers

Answer 1

Answer: We have to calculate the area of the box.

area (box)=2(lenght x width) + 2(lenght x height) +2(width x height)

area (box)=2(15 in x 7 in) + 2(15 in x 9 in) + 2(7 in x 9 in)=
=2(105 in²)+2(135 in²)+2(63 in³)=210 in²+270 in²+126 in²=606 in².

Answer: she need 606 in² of wrapping paper.

A bottlenose dolphin is 10 feet below sea level. Then it begins to dive at a rate of 9 feet per second. What is the equation of the line that represents its elevation, y, after x seconds?A.
y = 9x − 10
B.
y = -9x − 10
C.
y = 9x + 10
D.
y = -9x + 10

Answers

B is the correct answer

Answer:

B. y=-9x-10

Step-by-step explanation:

The dolphin is starting 10 feet below sea level so the y-intercept (or b in slope-intercept form) would be negative 10. Diving means going down, or a negative slope, so the slope would be -9. When you plug those numbers into y=mx+b, you would get y=-9x-10.
