Answer:

PART A: 28 hours, PART B: 16800 minutes

Step-by-step explanation:

Delia Brushes her teeth = 1/6 hour

PART A

Total Week= 1 week

Total number of days in a week= 7 days

Total number of hours in a day= 24 hours

Total number of hours in a week= 24× 7 hours

Total number of hours in a week= 168 hours

Number of hours that Delia brushes her teeth = $\frac{1}{6}$ × 168 hours

Number of hours that Delia brushes her teeth = 28 hours

Hence, the correct answer is 28 hours

PART B

Total number of days in a week= 7 days

Total number of hours in a week= 168 hours

Total number of minutes in a week= 168 × 60

Total number of hours in a week= 100800 Minutes

Number of minutes that Delia brushes her teeth = $\frac{1}{6}$ × 100800

Number of hours that Delia brushes her teeth = 16800 minutes

Hence, the correct answer is 16800 minutes

Steps for showing percent of 2028÷30%

4vir4ik [10]

2028/x=100/30
(2028/x)*x=(100/30)*x we multiply both sides of the equation by x
2028=3.3333333333333*x we divide both sides of the equation by (3.3333333333333) to get x
2028/3.3333333333333=x 
608.4=x 
x=608.4
so there for its 608.4 hope this helps.

A life guard in a tower 20 ft above sea level spots a struggling surfer at an angle of depression of 15 . How far is the surfer

GalinKa [24]

Answer: $19.31\ ft$

Step-by-step explanation:

Given

The tower is at a height of $h=20\ ft$

the angle of depression is $15^{\circ}$

Suppose the surfer is x ft away from the base of the tower

$\therefore \text{From the figure, we can write}\\\\\Rightarrow \cos 15^{\circ}=\dfrac{x}{h}\\\\\Rightarrow x=h\cos 15^{\circ}\\\Rightarrow x=20\cos 15^{\circ}\\\Rightarrow x=19.31\ ft$
