distance from point A to point B. Round your answer to the nearest tenth of a foot if
necessary.
Answers
Answer:2304.9
Step-by-step explanation:
Answer:
2304.9 ft
Step-by-step explanation:
You want the distance from point A, which is 1246 ft horizontally from a lighthouse to point B, given the angles of elevation to the light are 14° and 5° from points A and B, respectively.
TangentThe tangent relation for sides in a right triangle is ...
Tan = Opposite/Adjacent
In a model of this geometry, the height (h) of the lighthouse is the side opposite the angle of elevation. This lets us write two equations:
tan(14°) = h/1246
tan(5°) = h/(1246 +d) . . . . . where d is the distance from A to B
SolutionSolving these equations for d, we have ...
h = 1246·tan(14°) = (1246+d)·tan(5°)
d·tan(5°) = 1246·(tan(14°) -tan(5°))
d = 1246·(tan(14°)/tan(5°) -1) ≈ 2304.9 . . . . feet
The distance from point A to point B is about 2304.9 feet.

Answers
Answer:
Step-by-step explanation:
You just need to remember to first convert percentages to decimal form by dividing the percent by 100. Then you can work out the calculations.
Also, remember that if the problem is asking you to find a percentage, you need to turn your decimal answer to a percentage by multiplying by 100.
I used x to represent what we are looking for:
6.5% of $400 = x
0.065 * 400 = $26
12.5% of 100 = x
0.125 * 100 = $12.5
x of 650 = 130
130/650 = 0.2 which equals 20%
x of $4.50 = $5.40
5.40/4.50 = 1.2 which equals 120%
x of $28 = $8.40
8.40/28 = 0.3 which equals 30%
56% of x = $21.84
21.84/0.56 = 39
55% of x = $495
495/0.55 = 900
x of 400 = 120
120/400 = 0.3 which equals 30%
4% of 975 = x
0.04 * 975 = 39
Answer:
See below
Step-by-step explanation:
a. 6.5% of $400:
[tex]= \frac{65}{100}[/tex]× ($400)
= $260
b. 12.5% of $100:
[tex]= \frac{12.5}{100}[/tex] × ($100)
= $12.5
c. 130 is what percent of 650:
[tex]=\frac{130}{650}[/tex]×100%
= 20%
d. $5.40 is what percent of $4.50:
[tex]= \frac{5.40}{4.50}[/tex]×100%
= 120%
e. $8.40 is what percent of $28:
[tex]= \frac{8.40}{28}[/tex]× 100%
= 30%
f. 56% of what number is $21.84:

does this make sense?
Answers
The pattern for the hypotenuse in the Pythagorean spiral is √(a² + b²)
How to get the patternThe Pythagorean spiral is formed by drawing squares whose side lengths are given by the Pythagorean triples, which are sets of three positive integers (a, b, c) that satisfy the equation a² + b² = c².
In the Pythagorean spiral, the hypotenuse of each square is the diagonal of the square, which is given by the square root of the sum of the squares of the sides. For a square with side lengths a and b, the hypotenuse (diagonal) is given by:
√(a² + b²)
Since the side lengths of each square in the Pythagorean spiral are given by the Pythagorean triples, the hypotenuse of each square can be calculated using the Pythagorean theorem. Therefore, the pattern for each hypotenuse in the Pythagorean spiral is that it is given by the square root of the sum of the squares of the side lengths, where the side lengths are integers that form a Pythagorean triple.

Explain how to find 20% of 160
Answers
Answer: 20% of 160 is 32.
Step-by-step explanation:
The percentage is from the word percent which means one part in a hundred. It is a part of the base or the whole determined by the rate. Usually, the percentage is smaller than the base. However, there are also cases where the percentage is greater than the base. This happens when the percent is greater than 100%.
To find the percentage, you have to multiply the base and the rate. The base is the 100% or original amount or the whole while the rate is the ratio of the percentage to the base and it has the percent sign (%). Remember that you have to convert the rate to a decimal number by moving the decimal point twice to the left.
Let us now find the 20% of 160.
20% = 0.2
percentage = 160 × 0.2

B is significantly more affordable and better than A, renting for $1.62 per square foot.
Yard and feet conversion:Yard and feet are used to estimate the length. Both of the units are used in the royal and US customary system of measurements. The value of one yard is equal to three feet.
To compute Square yard to Square Feet, where Square yard is equal to 9 Square Feet, multiply the value in Square yard by 9. one can also use the Square yard to Square Feet calculator.
1 yard² = 9 feet²
A rents for $33 per yard squared
hence A rents $33 for 9 feet squared
hence A rents $3.67 per feet squared( $33/9) which is costlier than $1.49 per feet squared
Thus, as B is more economical, it is better.

What is an expression?
In mathematics, an expression is a combination of numbers, symbols, and operators (such as +, -, ×, ÷, and parentheses) that represents a quantity or a mathematical relationship. Expressions can be simple or complex, depending on the number of terms and the complexity of the operations involved.
The given expression is
[tex]\frac{6x^2y^{-1}}{\sqrt[4]{16x^5y^2} }[/tex]
To simplify the given expression and write it in the form of ax^by^c, we can start by using the properties of exponents and simplifying the numerator and denominator separately:
Numerator: [tex]6x^2y^(-1) = \frac{6x^2}{y}[/tex]
Denominator: [tex]\sqrt[4]{(16x^5y^2)} = (16x^5y^2)^{(1/4)} = 2x^{(5/4)}y^{(1/2)}[/tex]
Putting the simplified numerator and denominator together, we have:
[tex]\frac{6x^2y^{-1}}{\sqrt[4]{16x^5y^2}} = \frac{6x^2}{y} \cdot \frac{1}{2x^{5/4}y^{1/2}} = \frac{3}{\sqrt{2} \cdot x^{3/4}y^{3/2}}[/tex]
Now we can see that the given expression can be written in the form of ax^by^c, where a = 3, b = -3/4, and c = -3/2. Therefore, the product of a, b, and c is:
a * b * c = 3 * (-3/4) * (-3/2) = 27/8.
Hence, the product of a, b, and c is 27/8.

The piecewise function for the given problem is;
C(x) = $61.29 x ≥ 400
C(x) = $61.29 + 0.6(x - 400) if x ≥ 400
How to identify the Piecewise Function?A piecewise function is defined as a function that has different definitions depending on which values of x are being used. Piecewise functions are called "piecewise" due to the fact that they are made of "pieces" with different function definitions. To evaluate a piecewise function for a given value of x, find which interval your value fits in, and then use that definition of the function to evaluate.
First, we will find the monthly cost if the 400-minute monthly limit is not exceeded. Then, the total cost would be;
47.35 + 13.94 = 61.29 with just the plan and taxes. So if x ≤ 400, then;
C(x) = 61.29
Now if the 400 minutes is exceeded, the bill will also include $0.60 per additional minute. To find the number of additional minutes, we can take the total number of minutes x and subtract 400. In general, the cost would be;
C(x) = $61.29 + 0.6(x - 400) if x ≥ 400

what is 3 1/4-1 3/4 on number line place a point on 3 1/4 and on the difference may use skip counter to show 1 3/4
Answers
The difference between 3.25 and 1.75 is done and marked on the number line as below.
What is meant by a number line?
A number line is a representation of a graduated straight line that is used to represent real numbers visually. It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point. This line is used to compare integers on an endless line that extends on both sides, either horizontally or vertically, at equal intervals.
We are asked to plot the difference between 3 [tex]\frac{1}{4}[/tex] and 1 [tex]\frac{3}{4}[/tex] on the number line.
3 [tex]\frac{1}{4}[/tex] = 3 + 1/4 = 3 + 0.25 = 3.25
1 [tex]\frac{3}{4}[/tex] = 1 + 3/4 = 1 + 0.75 = 1.75
Difference = 3.25 - 1.75 = 1.5 = 1 [tex]\frac{1}{2}[/tex]
This can be shown on the number line below.
Each division has the value of 1/4 = 0.25.
We have marked 3[tex]\frac{1}{4}[/tex] = 3.25 on the number line.
Since we are subtracting 1 [tex]\frac{3}{4}[/tex] = 1.75 from 3.25, we move 7 divisions backward from 3.25 as 7 * 0.25 = 1.75.
So after moving 7 divisions backwards, we land on 1.5, which is the difference we found earlier.
Therefore the difference between 3.25 and 1.75 is done and marked on the number line as below.

Answer:
20 cubic yards
Step-by-step explanation:
You want to know the volume in cubic yards of a layer of topsoil that is 6 inches deep over an area 31 feet by 34 feet.
UnitsYou know that ...
36 inches = 1 yard3 feet = 1 yardThen the dimensions of the volume being applied are ...
6 inches = 6/36 yards
31 feet = 31/3 yards
34 feet = 34/3 yards
VolumeThe volume is the product of the dimensions of the space:
V = LWH
V = (31/3 yd)(34/3 yd)(6/36 yd) ≈ 19.519 yd³
About 20 cubic yards are needed to fill the garden.
What is the frequency of the function given? f(x)=9cos(4πX)+10
Answers
Answer:
Step-by-step explanation:
The frequency of a cosine function is related to the number of cycles that the function completes in a unit interval (usually in 2π radians).
The frequency of a cosine function with the form f(x) = A * cos(Bx + C) is given by B/(2π), where A, B, and C are constants.
For the function f(x) = 9cos(4πx) + 10, the frequency is given by 4π / (2π) = 2 cycles per unit interval.
So, the frequency of the function f(x) = 9cos(4πx) + 10 is 2 cycles per unit interval.

Answers
Hannah needs 150.71 gallons of soda and 17.29 gallons of fruit drink to make 168 gallons of punch that costs $1.66 per gallon.
What is meant by budget?
Budget is a planning and monitoring tool used by management to coordinate all of the company's activities. Budgeting is the process of estimating income and expenses for a given time frame.For any individual, group of people, organisation, or government. A budget is a plan for financial calculations for a specified time period, usually a month or a year, but not always.Budgeting is the process of estimating a company's revenues and expenses for a given time period.Examples of budgets prepared for this purpose include the sales budget, which makes a projection of the company's sales, and the production budget, which makes a projection of the company's production, among others.Let's assume that Hannah needs to use x gallons of soda and y gallons of fruit drink to make 168 gallons of punch.
We know that the cost of soda is $1.57 per gallon and the cost of fruit drink is $2.41 per gallon, and Hannah's budget requires that the punch cost $1.66 per gallon.
So we can set up the following system of equations:
x + y = 168 (total amount of punch)
1.57x + 2.41y = 1.66(168) (total cost of punch)
Simplifying the second equation:
1.57x + 2.41y = 278.88
Now we can use substitution or elimination method to solve for x and y.
Using substitution:
x = 168 - y
1.57(168 - y) + 2.41y = 278.88
264.36 - 1.57y + 2.41y = 278.88
0.84y = 14.52
y = 17.29
So Hannah needs 17.29 gallons of fruit drink.
Using x + y = 168, we can find that she needs 150.71 gallons of soda.
Therefore, Hannah needs 150.71 gallons of soda and 17.29 gallons of fruit drink to make 168 gallons of punch that costs $1.66 per gallon.
