DRAWING CONCLUSIONS "Hang time" is the time you are suspended in the air during a jump. Your hang time t (in seconds) is given by the function t = 0.5h , where h is the height (in feet) of the jump. Suppose a kangaroo and a snowboarder jump with the hang times shown. a. Find the heights that the snowboarder and the kangaroo jump. Round your answer to the nearest tenth.

The snowboarder jumps about___ I feet and the kangaroo jumps about___feet.

b. Double the hang times of the snowboarder and the kangaroo and calculate the corresponding heights of the each jump. Round your answer to the nearest

tenth.

The snowboarder jumps about___ feet and the kangaroo jumps about___feet.

c. When the hang time doubles, does the height of the jump double? Explain.

___, because when the hang time doubles, the height___by a factor of___.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

part d

step-by-step explanation:

theresa talked her parents into getting sd cards for her phone and her brother’s phone. inserting an sd card into a phone gives it more storage. they both get 8-gigabyte sd cards. how many bits of storage come with each sd card? type your answer in both scientific and standard notation.

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3
