Answer:
tan(47)=53/z
Step-by-step explanation:
Using trig ratio tan(x)=O/A
there x is the angle of elevation, O is the side opposite the angle (the lighthouse) and A is the side adjacent the angle (distance between boat and bottom of lighthouse)
Therefore, tan(47)=53/z
[tex]\\ \tt\hookrightarrow tan47=\dfrac{H}{B}[/tex]
[tex]\\ \tt\hookrightarrow tan47=\dfrac{53}{B}[/tex]
[tex]\\ \tt\hookrightarrow B=\dfrac{53}{tan47}[/tex]

Recycled CDs, Incorporated, offers a choice of 5 used CDs for $20, with each additional CD costing $6. Write a cost function for purchasing 5 or more CDs. What will the cost of buying 9 CDs be? Let x represent the number of CDs over 5.
the answer will be
48$ dollars
Answer:
20 + 6x
$44
Step-by-step explanation:
So 5 CD's for 20 dollars is $4 ea. then each one added will be +6 with the variable (x).
so you can't have the first 5 becuase x is used for every one OVER 5.
So
$ or price = 20 + 6x
plug 4 in because 9-5 = 4
20 + 6(4)
20 + 24
$44

)) A cylinder has a height of 9 meters and a diameter of 34 meters. What is its volume?
Use a = 3.14 and round your answer to the nearest hundredth.
Answer:
Volume of a sphere is (pi)*(r^2)*(h), where r is raduis, h is height, and pi is 3.14.
Diameter is 24/2 = 12
We just need to plug everything in.
(3.14)*(12^2)*(14) = 6330.24

4%
6%
40%
60%
Answer:
40%
Step-by-step explanation:
Flips 600 times, that's the total flips. ###/600
Heads flipped 240 times, and that's what you're looking for. 240/600
240/600 simplified is 2/5 (0.4)
You're looking for a frequency/percentage so you're looking at the decimal
Decimal number = Percentage

1. The table shows the prices of 3 boxes of laundry detergent of different sizes. Which size box costs the least per ounce? Explain your answer. Size Price 150 OZ 100 oz $18.97 $11.97 $8.97 56 OZ
The table is an illustration of unit rates
Box 2 has the least price per ounce
How to determine the least per ounce
The given parameters are:
Box 1 = $18.97 per 150 Oz
Box 2 = $11.97 per 100 Oz
Box 3 = $8.97 per 56 Oz
Divide the price by the sizes, to get the rates
[tex]Box 1 = \frac{18.97}{150} =0.126}[/tex]
[tex]Box 2 = \frac{11.97}{100} =0.1197}[/tex]
[tex]Box 3 = \frac{8.97}{56} =0.160[/tex]
By comparison, 0.1197 is the least
Hence, box 2 has the least price per ounce

Help please!!! I really don’t know how to do this!
Answer:
I'm going to do 1 as an example and using what I've taught you, you have to do the rest. Hope my explanation helps.
Step-by-step explanation:
We are given the points (-2, -4) and (-1, -1)
We need to find the slope.
The equation to do so is y2 - y1 / x2 - x1
lest say:
-2 is x1
-4 is y1
-1 is x2
-1 is y2
-1 - (-4) / -1 - (-2)
3/1 = 3
slope (m) = 3
We already know the y-intercept is 2
The equation of a line is y = mx + b
For this problem we just have to substitute what we already know.
y = (slope)x + y-intercept
y = 3x + 2
*TIP*
If the y-intercept is negative, let's say: b = -5 (using slope 8)
the equation will be y = 8x - 5
Hope this helps. I wish you all the best. :)

Please I need help with this problem
Step-by-step explanation:
First problem looks right. Although he started with 145, not 25. Savings and checking combined is the total amount of cash he had before he started working, which is why it's added to the total amount of money he has.
He saves 55 every week. because the multiplier on w, which is weeks is 55. So for every week 55 is added to the multiplication. Ex 2 weeks is 110, 3 is 165, 4 is 220 etc..
He wanted a total of 650 usd. Doesn't matter where it is the total is what matters. Doesn't matetr if hes spending, storing or even burning the money..
So first make 55w+145=650 then solve
Minus 145 from both sides
55w = 505
About 9 weeks one day and 6 hours. This is a rough estimate since the answer is 9.18181818 weeks.
The area of this polygon is 228 square meters
What is the length of the side labeled with a question mark
Enter your answer in the box
Answer: 7
Step-by-step explanation:
Let the unknown length be x
Cut the polygon into 2 pieces
6 * 24 + x * (18 - 6) = 228
144 + 12x = 228
12x = 84
x = 7
The length of the side labeled with a question mark in the given polygon is 7 meters.
What is area?Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.
Given that, the area of this polygon is 228 square meters.
We know that, the area of a rectangle is Length×Breadth
Area of a large rectangle = 24×6
= 144 square meters
Let the length of unknown side be x.
Area of a small rectangle = 12×x
Total area = Area of a large rectangle+Area of a small rectangle
228=144+12x
12x=228-144
12x=84
x=84/12
x=7 meters
Therefore, the length of the side labeled with a question mark is 7 meters.

find the radius of cylinder with a volume of 108pi ft3 and height of 12 ft
The volume of a cylinder is the amount of space in it
The radius of the cylinder is 3 feet
How to calculate the radiusThe volume of a cylinder is:
[tex]V = \pi r^2 h[/tex]
Where r represents the radius, and h represents the height
So, we have:
[tex]108\pi = \pi r^2 * 12[/tex]
Divide both sides by 12pi
[tex]9 = r^2[/tex]
Take the square roots of both sides
3 = r
Rewrite as:
r = 3
Hence, the radius of the cylinder is 3 feet

2x² + 3 = 39 extracring square roots
Answer:
x=9
Step-by-step explanation:
first, subtract 3 from both sides so 2x^2=36, then, divide both sides by 2 so x^2=18 and divide 18 by 2 and 9^2=18
Answer:
x = ± 3[tex]\sqrt{2}[/tex]
Step-by-step explanation:
2x² + 3 = 39 ( subtract 3 from both sides )
2x² = 36 ( divide both sides by 2 )
x² = 18 ( take square root of both sides )
x = ± [tex]\sqrt{18}[/tex] = ± [tex]\sqrt{9(2)}[/tex] = ± ( [tex]\sqrt{9}[/tex] × [tex]\sqrt{2}[/tex] ) = ± 3[tex]\sqrt{2}[/tex]
