Just keep multiplying by fractions equal to ' 1 '
until you have the units you need:
(6.4 x 10⁻⁸ mi/day) x (1 day / 24 hr) x (5280 ft/mi) =
(6.4 x 10⁻⁸ x 5280 / 24) (ft/hr) = 1.408 x 10⁻⁵ ft/hr
Answer:
1.408 x 10⁻⁵ ft/hr

The angle of elevation must be 68.202 degrees
Solution:
Given that, 14 foot ladder is used to scale a 13 foot wall
We have to find the angle of elevation must the ladder be situated in order to reach the top of the wall
The figure for this solution is attached below
The ladder, wall and the ground forms a right angled triangle
ABC is a right angled triangle
AB is the height of wall = 13 feet
AC is the length of ladder = 14 feet
We have to find the angle of elevation
Let the angle of elevation be "x"
For right angled triangle ABC, We can use the definition for sine
Here, in figure, opposite = AB and hypotenuse = AC
Thus the angle of elevation must be 68.202 degrees
The angle of elevation the ladder will be situated in order to reach the top of the wall is 68°.
What is a right triangle?
A right triangle has one of its angles as 90 degrees. The angle of elevation can be found using trigonometric ratios.
Therefore, the angle of elevation can be calculated as follows;
The length of the ladder is the hypotenuse.
The opposite side is the height of the wall.
Therefore,
sin ∅ = opposite / hypotenuse
sin ∅ = 13 / 14
∅ = sin⁻¹ 0.92857142857
∅ = 68.2129901712
∅ = 68°

The exact quotient of 162 ÷ 19 is 8 with a remainder of 10.
To estimate the quotient of 162 divided by 19, you can use rounding or long division.
Rounding:
Round 162 to the nearest tens place, which is 160.
Round 19 to the nearest tens place, which is 20.
Divide 160 by 20: 160 ÷ 20 = 8.
So, the estimated quotient of 162 ÷ 19 is approximately 8.
Long Division:
Perform long division to find the exact quotient of 162 ÷ 19:
8
___________
19 | 162
- 152
-----
10
Hence, the exact quotient of 162 ÷ 19 is 8 with a remainder of 10.

6 people= 12 servings so 1 person= 2 servings
We have 112 people so we need 112 x 2= 224 servings
So she will make 224 servings with an 8 servings pan, 224/8= 28 pans.
The minimum number of pans she need in order to serve 112 people is 28 pans!
