Terrence finished a word search in the time it took Frank. Charlotte finished the word search in the time it took Terrence. Frank finished the word search in 32 minutes. How long did it take Charlotte to finish the word search?
Answer:
Charlotte finished the word search in 16 minutes
Step-by-step explanation:
Terrence finished a word search in 3/4 the time it took frank. charlotte finished the word search in2/3 the time it took terrence. Frank finished the word search in 32 min. how long did it take charlotte to finish the word search
Frank finished the word search in 32 min
Terrence finished a word search in 3/4 the time it took frank
Terrence = 3/4 of 32 min
= 3/4 × 32 minutes
= (3×32)/4
= 96/4
= 24 minutes
Terrence finished a word search in 24 minutes
Charlotte finished the word search in 2/3 the time it took Terrence
Charlotte = 2/3 of 24 minutes
= 2/3 × 24
= (2×24)/3
= 48/3
= 16 minutes
Charlotte finished the word search in 16 minutes

Val needs to find the area enclosed by the figure. The figure is made by attaching semicircles to each side of a 42m-by-42m square. Val says the area is 1005.48 m^2. Find the area enclosed by the figure. Use 3.14 for pi. What error might Val have made?
Thanks in advance!
I don't have anymore points so please make a good and accurate answer.
Answer:
Area of the enclosed figure = 3148.74 [tex]m^{2}[/tex]
Step-by-step explanation:
Area enclosed by the figure = 2 x area of the semicircle + area of the square
For the semicircle,
radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{42}{2}[/tex]
= 21 m
area of a semicircle = [tex]\frac{1}{2}[/tex] x [tex]\pi r^{2}[/tex]
= [tex]\frac{1}{2}[/tex] x 3.14 x [tex](21)^{2}[/tex]
= 692.37 [tex]m^{2}[/tex]
area of a square = length x length
= 42 x 42
= 1764 [tex]m^{2}[/tex]
Thus,
area enclosed by the figure = 2 x 692.37 + 1764
= 3148.74 [tex]m^{2}[/tex]
The total area enclosed bu the figure is 3148.74 [tex]m^{2}[/tex]

Answer:
{0, 1, 16, 81}
Step-by-step explanation:
If the domain of this function is the set {0, 1, 4, 9}, we find the set representing the range by evaluating the function at each of the four values in the domain.
f(0) = 0
f(1) = 1
f(4) = 16
f(9) = 81
and so the range is the set {0, 1, 16, 81}.

McCoy's parents start a bank
account for him with $200.
His parents agree to pay him $30 a I
week to clean the house and mow
the lawn. Write an equation he could!
use that will show the total amount
saved (y) and the number of weeks
works(w).
Answer:
The ideal equation form to write this in would be "y=mx+b" because it involves a starting amount (which is represented by "b") and a certain constant amount of something ("m") being fed into that starting amount over time ("x" which will be substituted for "w" because the math problem wants us to substitute). Plugging in the number's you get:
y=30w+200
Step-by-step explanation:
y---> total amount saved after plugging in all numbers including time
m--> amount of money/stuff being added to the starting point over time
x---> can represent time, or basically any independent variable that decides how long has the stuff been being fed into the overall number
b---> the starting point (in this case it is 200, in other cases it can be anything, even a negative number)
Have a wonderful day!

Help pls ! This is trigonometric function
Answer:
Amplitude: 4
Period: π
midline: y = 1
Step-by-step explanation:
r(x) = -4 sin(2x) + 1
r(x) = a sin(bx + c) + d where |a| is the amplitude and |b| for the period
a = -4 |a| = 4 : Amplitude = 4
b = 2 |b| = 2 period of sin(x) = 2π
period of sin(bx + c) = 2π/|b| = 2π/2 = π
range of sin(2x) ... -1 ≤ sin(2x) ≤ 1
range of -4 sin(2x) + 1: -4+1 ≤ -4 sin(2x) + 1 ≤ 4+1
-3 ≤ -4 sin(2x) + 1 ≤ 5
midline: y = (-3 + 5) / 2 = 1 y = 1
Answer:
Part A: The amplitude [tex]\displaystyle r[/tex]is [tex]\displaystyle 4.[/tex]
Part B: The period of [tex]\displaystyle r[/tex]is [tex]\displaystyle \pi.[/tex]
Part C: The equation of the midline of [tex]\displaystyle r[/tex]is [tex]\displaystyle y = 1.[/tex]
Step-by-step explanation:
[tex]\displaystyle \boxed{r(x) = -4cos\:(2x - \frac{\pi}{2}) + 1} \\ \\ r(x) = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 1 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{\frac{\pi}{4}} \hookrightarrow \frac{\frac{\pi}{2}}{2} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{\pi} \hookrightarrow \frac{2}{2}\pi \\ Amplitude \hookrightarrow 4[/tex]
OR
[tex]\displaystyle r(x) = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 1 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{\pi} \hookrightarrow \frac{2}{2}\pi \\ Amplitude \hookrightarrow 4[/tex]
Keep in mind that although this IS a sine function, if you plan on writing your equation as a function of cosine, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the centre photograph displays the trigonometric graph of [tex]\displaystyle r(x) = -4cos\:2x + 1,[/tex]in which you need to replase "sine" with "cosine", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the sine graph [photograph on the left], accourding to the horisontal shift formula above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the cosine graph [centre photograph] is shifted [tex]\displaystyle \frac{\pi}{4}\:unit[/tex]to the left, which means that in order to match the sine graph [photograph on the left], we need to shift the graph FORWARD [tex]\displaystyle \frac{\pi}{4}\:unit,[/tex]which means the C-term will be positive, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{\frac{\pi}{4}} = \frac{\frac{\pi}{2}}{2}.[/tex]So, the cosine graph of the sine graph, accourding to the horisontal shift, is [tex]\displaystyle r(x) = -4cos\:(2x - \frac{\pi}{2}) + 1.[/tex]So, with all that being said, to find the period, again, take a look at the above information next to [tex]\displaystyle Wavelength\:[Period].[/tex]Now, the amplitude is obvious to figure out because it is the A-term. Moreover, the midline is the centre of your graph, also known as the vertical shift, which in this case the centre is at [tex]\displaystyle y = 1,[/tex]in which each crest is extended four units beyond the midline, hence, your amplitude. Now, there is one more piese of information you should know -- the sine graph in the photograph farthest to the right is the OPPOCITE of the sine graph in the photograph farthest to the left, and the reason for this is because of the negative inserted in front of the amplitude value. Whenever you insert a negative in front of the amplitude value of any trigonometric equation, the whole graph reflects over the midline. Keep this in mind moving forward. Now, with all that being said, no matter how far the graph shifts vertically, the midline will ALWAYS follow.
I am delighted to assist you at any time.
what is the value of x and y?
Answer:
The right answer is x = 8, y = 40.
Step-by-step explanation:
Since this triangle is isosceles we know that...
∠ACB = ∠ABC
40° = (5x)°
40 = 5x
x = 40 / 5
x = 8
We also know that the sum of all angles inside the triangle is equal to 180°, therefore...
∠BAC = 180° - ∠ACB - ∠ABC
(2y + 20)° = 180° - 40° - 40°
2y + 20 = 100
2y = 100 - 20
2y = 80
y = 80 / 2
y = 40
From this, we know that the right answer is x = 8, y = 40.

Jason's business computers need servicing. The expression 81x + 108 represents a contractor's total charges in dollars for fixing the problem. The expression 103x + 64 represents an electronic store's total charges in dollars for the same work. In both expressions, x is the number of hours it took to complete the job. What is the difference in the total charges for a repair job that takes 45 minutes? Explain.
Answer:
The Jason's company charges more than the contractor's company.
Step-by-step explanation:
There are two expressions given for total charges for two companies as 81 x+108 and 103 x+64.
Here x represents number of hours.
We are asked to find difference in total charges if that takes 45 minutes.
45 minutes = [tex]\frac{3}{4}[/tex] hours.
Plug in this value for x.
81x+108 =[tex]81*\frac{3}{4} +108[/tex]
Simplify it
60.75 +108 =168.75
Now, for 103x+64 =[tex]103 *\frac{3}{4} +64[/tex]
Simplify it,
77.25+64=141.25
If we see the total charge for both companies for 45 minutes, the Jason's business computers charges more than contractor's company.

what is the measure in degrees
Answer:
B = 155°, C = 25°, D = 155°
Step-by-step explanation:
Assuming you require B, C, D
A and B are adjacent angles and are supplementary , that is
A + B = 180°
25° + B = 180° ( subtract 25° from both sides )
B = 155°
A and C are vertically opposite angles and are congruent, then
C = 25°
B and D are vertically opposite angles and are congruent , then
D = 155°
