The approximate angle of elevation from the point on the bottom is; D: 53.1°
What is the angle of elevation?We are told she dived into a pool that is 8 ft deep.
Now, she could touch the bottom with her hands 6 ft horizontally. Thus;
We can use trigonometric ratio to determine the approximate angle of elevation from the point on the bottom of the pool where she touched to her entry point.
If the angle of elevation is θ, then we have;
θ = tan⁻¹(8/6)
θ = 53.1°

You have twenty blankets that each take up 704 cubic inches of space. How many blankets could you pack into a 22-inch moving box?
Answer:
32
Step-by-step explanation:
i don't know if its right but i did 704 divided by 22 which equals to 22
We can pack a maximum of 15 blankets into the 22-inch moving box.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To determine how many blankets can fit in a 22-inch moving box, we first need to calculate the volume of the box.
Since the box is 22 inches in all three dimensions (length, width, and height), its volume is:
= 22 x 22 x 22
= 10,648 cubic inches
Next, we need to divide the volume of the box by the volume of one blanket to find out how many blankets can fit inside.
= 10,648 / 704
= 15.125
We can't fit a fraction of a blanket, so we can only pack a whole number of blankets.
Therefore,
We can pack a maximum of 15 blankets into the 22-inch moving box.

A stack of 500 pieces of paper is 1.015 inches tall. What is an appropriate estimate for the thickness of each piece of paper?
Answer: 0.002 inches
Step-by-step explanation:
A stack of 500 pieces of paper is 1.015 inches tall. The appropriate estimate for the thickness of each piece of paper would be gotten by dividing 1.015 by 500. This will be:
= 1.015 / 500
= 0.00203
= 0.002 inches

What is the image point of (7,-7) after a translation of 3 right and 1 down followed by
a reflection over the x-axis?
Answer:
The image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:
P''(10, 8)Step-by-step explanation:
Given the point
(7, -7)
Translation of 3 right and 1 down means we need to add 3 units to the x-coordinate and subtract 1 unit from the y-coordinate
Therefore, the translation rule:
(x, y) → (x+3, y-1)
In our case, let the point P(7, -7)
P(7, -7) → P'(7+3, -7-1) → P'(10, -8)
FOLLOWED BY A reflection over the x-axis
We know that the rule of reflection over the x-axis implies that
(x y) → (x, -y)
i.e. the x-coordinate of the point remains the same, but the y-coordinate changes its sign.
After the first transformation, we had got P'(10, -8)
so
P'(10, -8) → P''(10, -(-8)) → P''(10, 8)
Therefore, the image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:

The following points for the function C(w) can be concluded as
The function C(w) is valid only for {w} greater than 16 ounces.The initial cost is $1.6.The cost of shipping per ounce is $0.35.What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that the Quick Ship company uses the function C(w) to calculate the cost in dollars {C} for shipping an item weighing {w} ounces as
C(w) = 0.35W + 1.6 if {w > 16}

The ratio of paintbrushes to bottles of paint in Ms. Nelson's supply closet is 8 to 3.
If there are 48 paintbrushes, how many bottles of paint are there?
Answer:
Well, 48 divided by 8 is 6. And 6 times 3 is 18. So I belive that there would be 18 bottles of paint.
Step-by-step explanation:
The number of bottles of paintbrushes is 18.
What is a fraction?Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A ratio shows how often one number is contained in another.
For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.
Given that the ratio of paintbrushes to bottles of paint in Ms. Nelson's supply closet is 8 to 3. If there are 48 paintbrushes.
The number of the bottles will be calculated as:-
P / B = 8 / 3
3P = 8B
3 x 48 = 8B
B = 3 x 6
B = 18
Therefore, the number of bottles of paintbrushes is 18.

Find the distance along an ark on the surface of the earth that subtends a central angle of 10 minutes (1 minutes 1/60 degree) The radius of the earth is 3960 miles around to the thousands
Answer:
11.52 miles
Step-by-step explanation:
We know that the length of an arc L = Ф/360 × 2πR where Ф = angle subtended by arc and R = radius of circle.
Now since Ф = 10 minutes = 10 × 1 minute = 10 × (1/60)° = (1/6)° and R = radius of earth = 3960 miles
So L = Ф/360 × 2πR
= (1/6)°/360 × 2π(3960 miles)
= 1/2160 × 7920π
= 3.67π
= 11.52 miles

The unknown values of number for each of the expression is 8, 10, 3000, 1440, and 25.
What is Percentage?A percentage is a portion of a whole number which is expressed as a number between the range of 0 and 100 rather than as a fraction. All of a thing is 100 percent, half of it is 50 percent, and none of something is zero percent. To determine a percentage, we divide the portion of the whole through the whole of itself and multiply it by 100.
x × 150/100 = 12
x = 12 × 100/ 150
x = 1200/ 150
x = 8
x × 50/100 = 5
x = 5 × 100/ 50
x = 500/ 50
x = 10
x × 10/100 = 300
x = 300 × 100/ 10
x = 30000/ 10
x = 3000
x × 5/ 100 = 72
x = 72 × 100/ 5
x = 7200/ 5
x = 1,440
x × 80/ 100 = 20
x = 20 × 100/ 80
x = 2000/ 80
x = 25
Therefore, the values of unknown numbers are 8, 10, 3000, 1440, and 25, respectively.

[tex]m = \frac{y_2 - y_1 }{x_2 - x_1}[/tex]
➊ First: We are going to be solving for the slope.
[tex]m = \frac{ - 9 - 6}{ - 1 - ( - 6)} = \frac{ - 15}{ \: \: \: 5} = - 3[/tex]
➋Second: We find the y-intercept.
[tex]y = mx + b \\ 6 = - 3( - 6) + b \\ 6 = 18 + b \\ \frac{ - 18 = - 18 \: \: \: \: \: \: \: \: \: \: \: \: }{ - 12 = b}[/tex]
