Answer:
A) 21d + 48 = 426
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
if the x is the like repeating one, then its the 21 per day, see it has per in it
for the 48, its just additional so we put it equal to 426 since thats the total amount giving us the equation
21d + 48 = 426
21d = 378
d= 18
it took 18 days

sin^-1(sin 17°)
Answer:
uhm 0 degrees
Step-by-step explanation:
The value of the inverse trigonometric expression sin⁻¹(sin 17°) will be 17°.
What is inverse trigonometry?Simply put, inverse trigonometric operations are the opposites of the fundamental trigonometric parameters sine, cosine, secant, cosecant, tangent, and cotangent.
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The inverse trigonometric expression is given below.
⇒ sin⁻¹(sin 17°)
We know that the value of sin⁻¹(sin θ) is θ.
Then the value of the inverse trigonometric expression will be
⇒ sin⁻¹(sin 17°)
⇒ 17°
Thus, the value of the inverse trigonometric expression sin⁻¹(sin 17°) will be 17°.

Alyssa is jogging near Central Park. She runs along 65th Street for about 0.19 miles, turns right and runs along Central Park West for about 0.28 miles. She then turns right again and runs along Broadway until she reaches her starting point. How long is her total run to the nearest hundredth of a mile?
A: 0.68 miles
B: 0.81 miles
C: 1.15 miles
D: 1.44 miles
Answer: B: 0.81 miles
Step-by-step explanation:
The find the total distance, you must look for firs the missing side. To get use the formula that is derived from the Pythagorean theorem which states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
The formula for this is: a^2 + b^2 = c^2
So let the first side or a be .19
and the second side be .28
and now we are looking for c which is the missing side
.19^2 + .28^2 = c^20.0361 + 0.784 = .1145
get the square root of .1145
√.1145 = it is approximately 0.34
get the total distance by adding three sides
= .34 + .19 + .28
= 0.81

Answer:
176 cm
Step-by-step explanation:
Area of a triangle = h b/2

Area of a rectangle = l * w
12 * 11 = 132 cm
Add both areas together
44 + 132 = 176 cm
Point P is at (3,-3) it undergoes the transformation (x - 2, y + 3). Where is P' at?
Answer:
The coordinates of P' are [tex]P'(x,y) = (1, 0)[/tex].
Step-by-step explanation:
The coordinates of the point P' is determined by the following expression:
[tex]P'(x, y) = P(x,y) + T(x,y)[/tex] (1)
Where:
[tex]P(x,y)[/tex] - Original point.
[tex]P'(x,y)[/tex] - Translated point.
[tex]T(x,y)[/tex] - Translation vector.
If we know that [tex]P(x,y) = (3, -3)[/tex] and [tex]T(x,y) = (-2, 3)[/tex], then the coordinates of point P':
[tex]P'(x,y) = (3, -3) + (-2, 3)[/tex]
[tex]P'(x,y) = (1, 0)[/tex]
The coordinates of P' are [tex]P'(x,y) = (1, 0)[/tex].

Circumference and Area questions look at the picture
Note that the formula for the circumference of a circle is πd, while the formula for the area of a circle is πr².
π≈3.14
A. C=πd
Simply plug in the numbers into the formula.
Diameter=Radius*2
17*2=34
C=34(π)
B. (π)(5²)
Plug in the numbers into the formula. Remember that half of the diameter is the radius.
C. (π)(4.5)
There are two possible formulas that could be used to calculate the circumference of a circle: πd and 2πr.
The expression above is simply multiplying the circle's radius times pi. Therefore, it is not a method that could be used to find the circumference of a circle.
D. (π)(6.5²)
Remember that the formula for calculating the area of a circle is πr².
Half of the diameter is 6.5 (13.5/2=6.5). 6.5 cm. is the radius. Now just plug the numbers into the formula.
(π)(6.5²)
Therefore, the last answer choice is the correct answer.
In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Arun sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below. 128 visitors purchased no costume. 3 visitors purchased exactly one costume. 5 visitors purchased more than one costume. Based on these results, express the probability that the next person will purchase exactly one costume as a fraction in simplest form.
Answer:
3/136
Step-by-step explanation:
128 + 3 + 5 = 136

Please help me with this problem.
Bernice uses the equation C = 2h + 8 to find the total cost, C, in dollars, of renting a boat for h hours. If Bernice does not spend more than $32, what is the maximum number of hours she can rent the boat?
a 8
b 12
c 20
d 22
Answer:
A
Step-by-step explanation:
Since she's not spending more than $32, the equation is 2h + 8 ≤ 32.
Isolate h to find the maximum number of hours she can rent the boat:
2h + 8 ≤ 32
First, subtract 8 from both sides.
2h ≤ 16
Then divide both sides by 2.
h ≤ 8
h, the number of hours, must be less than or equal to 8, so 8 is the maximum number of hours Bernice can rent the boat for.

Find the percentage of him drawing a blue marble.
4/10 = 0.4
He has a 40% chance of picking blue.
Find 40% of 30.
12
He would draw a blue marble around 12 times.
Answer:
C
Explanation:
So in the bag, there are 10 marbles, and 4 of them are blue, so if he drew from the bag 10 times, we can assume the fraction:
4/10
Next, we see that the denominator, or the number times Cade is drawing from the bag is 30, which makes us multiply most sides of the fraction by 3:
12/30
So I would say 12/30, but again, he wouldn't draw a blue exactly 4 times, and it may be more or less, so either 8/12....

Answer:
114cm²
Step-by-step explanation:
Okay, so you can split this thingy up into a rectangle and another rectangle, so that's what we're going to do (see pic below)
So now we take off that 7 from the 13:
13 - 7 = 6
So now we find the area of that little area:
6 x 5 = 30
Now we do the other rectangle:
12 x 7 = 84
Now we add them together:
84 + 30 = 114
So the area of the shape is 114cm²

Find a rational function that satisfies the given conditions. Answers may vary, but try to give the simplest answer possible:
Vertical asymptotes x = -4, x = 5;
x-intercept (-2, 0)
Answer:
[tex] \frac{x + 2}{ {x}^{2} - x - 20 } [/tex]
Step-by-step explanation:
Since the roots are -4 and 5, we can write that as
[tex](x + 4)(x - 5)[/tex]
Apply foil method to find our denominator.
We get
[tex] {x}^{2} - x - 20[/tex]
So that our denominator.
Since our denomiater gives us interger asymptote, our degree in our numerator must be 1 so the answer has to be a single interger or a single term.
Since our x intercepts is -2, we use
[tex](x + 2)[/tex]
So our rational denomiater is
[tex] \frac{x + 2}{ {x}^{2} - x - 20 } [/tex]

Harry bought a broken motor scooter, fixed it, and sold the scooter for $150. That was $25 less than 2 times the amount he paid for it. Which equation can be used to find, p, the amount of money Harry originally paid for the scooter?
Answer:
p/2 - 25 = 150
Step-by-step explanation:
I'll try my best.
$150 would be the initial value, so we would use that for the base.
$25 less means subtract 25 dollars in this context.
2 times means multiply by 2.
"$150 was $25 less than 2 times the amount he paid for it ([tex]p[/tex])."
[tex]\frac{p}{2} -25 = 150[/tex]
If you were to solve this:
[tex]\frac{p}{2} -25 = 150[/tex]
[tex]\frac{p}{2} =175[/tex]
[tex]p=350[/tex]
The answer I get from the equation would be $350.
If you input 350 into it:
[tex]\frac{(350)}{2} -25[/tex]
[tex]175 -25[/tex]
[tex]150[/tex]
Answer:
P = 150 ÷ 2 - 25 = p
Step-by-step explanation:
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you know two points that a line passes through, this page will show you how to find the equation of the line.
Given: Harry bought a broken motor scooter, fixed it, and sold the scooter for $150. $25 less than 2 times the amount he paid for it.
To find: Which equation can be used to find, p, the amount of money Harry originally paid for the scooter?
Solution: It says; "That was $25 less than 2 times the amount he paid for it"
With that said, find the amount that is 2 times more than 150. To find that, the opposite of times is division, so divide 150 by 2
[tex]150[/tex] ÷ [tex]2 =[/tex] [tex]75[/tex]
Now that has been found, the next thing to find is $25 less, less means subtract. To calculate the amount Harry originally paid for the scooter, subtract 25 from 75
[tex]75 - 25 = 50[/tex]
Therefore, the amount of money Harry originally paid for the scooter is $50
Hence, the equation can now be found as; P = 150 ÷ 2 - 25 = p
