Answer:
Distance between the plane and the observer is 511.86 miles.
Step-by-step explanation:
From the figure attached,
A plane is flying at point A which is at 200 m height and observer is at point C.
Angle of elevation (∠ACB) of the plane from the observer is 23°.
Let the distance between the observer and the plane is x meters.
By applying sine ratio for angle C,
sin(∠C) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(23°) = [tex]\frac{200}{x}[/tex]
x = [tex]\frac{200}{\text{sin}(23)}[/tex]
x = 511.86 miles
Therefore, distance between the plane and the observer is 511.86 miles.

Solve the original equation 2+1/b+2=3b/b+2 by solving the proportion. The solutions are
a.-6,-1 b. -6,1 c. -1,6 d. 1,6
Answer:
b=1
Step-by-step explanation:
2b+1+2b=3b+2b
4b+1=5b(Simplify both sides of the equation)
4b+1−5b=5b−5b(Subtract 5b from both sides)
−b+1=0
−b+1−1=0−1(Subtract 1 from both sides)
−b=−1
−b
−1
=

Amal has 1/2 pound of baked beans. She divides the beans into 8 equal servings. Write and solve an equation to find how many pounds of baked beans are in each serving
Answer:
1/16 pound or 0.0625 pound beans.
Step-by-step explanation:
According to the problem, calculation of given data are as follows,
Total baked beans = 1/2 pounds
Number of serving = 8
if distribute equal beans in each serving than,
8 serving = 1/2 pound
So, 1 serving = 1/(2×8) pound
= 1/16 pound or 0.0625 pound beans.
Hence, each serving consist of 0.0625 pound baked beans.

Describe how you know whether an equation will be true for all values of x or true for no values of x.
Answer:
Substitute your answer for the variable x. If the equation looks accurate or is correct, then the value of x is the right answer. Not sure if this makes sense
Determining whether an equation is true for all values of x or true for no values of x requires simplifying the equation, determining its domain, checking for variable restrictions, and evaluating the equation for different values of x.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Simplify the equation as much as possible using algebraic manipulations such as combining like terms, factoring, and expanding.
Evaluate the equation for a few different values of x to see if it holds true. If the equation is true for all values of x within the domain, then it will be true for all values of x. If there are any values of x within the domain that make the equation false, then it will be false for no values of x.
If the equation cannot be simplified or the domain cannot be determined, then it may require further analysis, such as graphing or using calculus techniques to determine its behavior.
Thus, determining whether an equation is true for all values of x or true for no values of x requires simplifying the equation, determining its domain, checking for variable restrictions, and evaluating the equation for different values of x.

Answer:
B
Step-by-step explanation:
The formula for a area of the first semi circle is
[tex] \frac{1}{2} \times \pi {r}^{2} [/tex]
where r is the radius
Since 4 is the diameter, 2 is the radius
plug it in
[tex] \frac{1}{2} \times \pi {2}^{2} [/tex]
[tex] \frac{1}{2} \times 4\pi[/tex]
[tex]2\pi[/tex]
so the area of the first circle is 2
[tex]2\pi[/tex]
now let find the second circle
Since the semi circle is twice the area of AB the diameter is 8 so the radius is 4.
Put it in the equation.
[tex] \frac{1}{2} \times \pi {4}^{2} [/tex]
[tex] \frac{1}{2} \times \pi \times 16[/tex]
[tex]8\pi[/tex]
Now let find the third circle
Since it is twice the size of the second circle, the diameter is 16 and the radius is 8.
[tex] \frac{1}{2} \times \pi {8}^{2} [/tex]
[tex] \frac{1}{2} \times 64\pi[/tex]
[tex]32\pi[/tex]
Now let add the area of the semi circle
[tex]32\pi + 2\pi + 8\pi = 42\pi[/tex]

Step-by-step explanation:
After his alarm rings, Clarence has
25 minutes to get ready. He snoozes in
bed for one minute after the alarm rings
the first day, two minutes the second
day, three minutes the third day, etc.
When Clarence is down to 11 minutes to
get ready, how many days has it been?
Answer: 14 days
Step-by-step explanation:
Day 1: 1 minute snooze = 24 minutes
Day 2: 2 minute nooze = 23 minutes ; these examples show snooze time = days.
We can set up an equation for this situation: 25 - s = r ; where s = snooze time and r = time to get ready.
Given the problem, we can fill out this equation with: 25 - s = 11
When you solve this equation, time snoozed = 14.
We already know that snooze time = days, so days = 14.

Wanda, the owner of an e-commerce site, buys skateboards for $50 and then sells them on her site for $83. What is the mark-up, as a percentage?
Answer: 66%
Step-by-step explanation:
Wanda buys the boards at $50 and sells them as $83.
The markup in actual dollar amounts is:
= 83 - 50
= $33
In percentage terms, the denominator will be the cost price:
= Markup / Cost price * 100%
= 33 / 50 * 100%
= 66%
Label each recursive routine as growth or decay (loss) and identify the percent of growth or decay.
a. Start with: 30
Rule: multiply by 1.07
growth by ????? percent
b. Start with: 100
Rule: multiply by 0.86
decay by ???? percent
c. Start with: 75
Rule: multiply by 1.125
growth by ?????? percent
Answer:
a. Rule: multiply by 1.07
1.07 = 107% = 100% + 7%
Growth by 7%
b. Rule: multiply by 0.86
0.86 = 86% = 100% - 14%
Decay by 14%
c. Rule: multiply by 1.125
1.125 = 112.5% = 100% + 12.5%
Growth by 12.5%
