Answer:
D, 342 meters
Step-by-step explanation:
We can use the definition of sines to solve the problem. Remember, sine = opposite leg over the hypotenuse of the triangle.
[tex]sin(<Q)= \frac{RS}{QR} \\[/tex]
Then, we can substitute QR for 1,000 and [tex]<Q[/tex] for 20 degrees and solve like so:
[tex]sin(20) = \frac{RS}{1,000}[/tex]
[tex]RS = 1000 (sin(20))\\\ RS = 1000(0.342)\\\\RS= 342.0201[/tex]
Rounding that number, we get 342 meters. Hope this made sense!
Answer: D. 342 m
Step-by-step explanation:
The given triangle is a right angle triangle since angle S is 90°.
From the given right angle triangle,
QR represents the hypotenuse of the right angle triangle.
With m∠Q as the reference angle,
QS represents the adjacent side of the right angle triangle.
RS represents the opposite side of the right angle triangle.
To determine RS, we would apply
the Sine trigonometric ratio.
Sin θ, = opposite side/hypotenuse. Therefore,
Sin 20 = RS/1000
RS = 1000Sin20 = 1000 × 0.342
RS = 342 m
What is the slope of the line that passes through the points (-9, -3) and (1, -3)?
Write your answer in simplest form.
Answer:
The slope is 0.
Step-by-step explanation:
m= (y2-y1)/(x2-x1).
y2 is -3, y1 is -3.
x2 is 1 and x1 is -9.
m= -3 -(-3)/ 1- (-9)
m= 0/10
m=0
The slope of the line that passes through the points (-9, -3) and (1, -3) is 0 because the y-coordinates of both points are the same and this results in a 'change in y' of 0.
Explanation:In mathematics, the slope of a line passing through two given points can be calculated by the formula: (y2 - y1) / (x2 - x1). Where y2 and y1 represent the y-coordinates of the two points and x2 and x1 represent the x-coordinates of the two points. However, in this particular case, we see that the y-coordinates of both points (-9, -3) and (1, -3) are the same as -3.
This means our 'change in y', or (y2 - y1), is equal to zero (-3 - -3 = 0). Any fraction with 0 as the numerator (0 divided by any number) is itself equal to 0. Therefore, the slope of the line that passes through the points (-9, -3) and (1, -3) is 0.

Grace is having trouble deciding what to order for dessert. The options are 4 different flavors of ice cream, 3 different flavors of cake, or 2 different flavors pie. If she were to choose one item at random, what is the probability that she will choose a cake?
Answer: The probability that she would choose cake is 0.33 (or 33%)
Step-by-step explanation: The number of all possible outcomes is given as follows;
4 (ice cream) + 3(cake) + 2(pie), that is 4 + 3 + 2 = 9
This means there is a possibility of 9 different outcomes if she decided to choose her dessert at random.
However, there are 3 flavors of cake available which means the possibility of choosing cake is 3.
Therefore the probability that she will choose a cake is give as,
P(Cake) = Number of required outcomes/Number of all possible outcomes
P(Cake) = 3/9
P(Cake) = 1/3 or 0.33
Therefore the probability that she would choose cake is 0.33 or 33%

PLS HELPP Mr. Clark needed to rent a moving van. Company A charges a rate of $90 per hour plus a $50 truck
fee. Company B charges $70 per hour plus a $90 truck fee. For what number of rental hours is the cost
for both companies the same?
Answer:
2 hours
Step-by-step explanation:
According to the information provided you can say that for company A, the total cost is equal to 90 for the number of hours plus the 50 fee. For company B, the total cost is equal to 70 for the number of hours plus 90.
90x+50= 70x+90
x= number of rental hours
Then, you have solve for x:
90x-70x=90-50
20x=40
x=40/20
x= 2
The cost for both companies is the same for 2 rental hours.
Answer:
h = 2 hrs
Step-by-step explanation:
Mr Clark needed to rent a moving Van.
Company A charges
cost = 50 + 90(h)
where
h = number of hours used
Company B charges
cost = 90 + 70(h)
where
h = number of hour used
The number of rental hours when both companies cost is same is when both the cost equation is equal to each other.
Therefore,
50 + 90(h) = 90 + 70(h)
50 - 90 = 70h - 90h
-40 = -20h
divide both sides by -20
h = -40/-20
h = 2 hrs

01 : 20
Hence, the play lasted for 1 hour 20 minutes.
What is the formula to find the vertex of a parabola?
Answer:
y = a(x - h)^2 + k (please give branliest)
Step-by-step explanation:
(h,k) are coordinates of a point on the parabola
this is derived by ax^2 + bx + c
The formula to find the vertex of a parabola is x = -b/(2a) and y = f(x). The vertex of a parabola is represented by the coordinates (x, y).
Explanation:The formula to find the vertex of a parabola is x = -b/(2a) and y = f(x). In the equation of a parabola y = ax² + bx + c, the vertex can be found by substituting the x-coordinate from the formula into the equation to get the y-coordinate. So, the vertex of a parabola is represented by the coordinates (x, y).
A motel finds it can rent 180 rooms when the room rate is $ 60 per day. For each $ 2 increase in the rate, two fewer rooms are rented. Find the room rate that maximizes daily revenue. The rate that maximizes revenue is $ .
Answer:
$7,200
Step-by-step explanation:
r=p × n
where
r=revenue
p = price per item
n = number of items sold
A change in price changes quantity ( number sold)
Variable x changes with price, then
Let
p+x=a dollar price increase
p-x= a dollar price decrease
n+x= an increase in quantity sold
n-x= a decrease in quantity sold
Therefore,
A $2 dollar increase in price=p+2x
2 decrease in room quantity sold= n-2x
Substituting in the above equation
r=(p+2x)*(n-2x)
P=$60
n=180
Then
r=(60+2x)*(180-2x)
r=10,800-120x+360x-4x^2
r=-4x^2-240x+10,800
Solve the quadratic equation
The maximum value of x in the vertex = - b/2*a
Where
b=240
a=-4
Value of x=-240/2*(-4)
X=30
r=-4x^2-240x+10,800
=-4(30)^2-240(30)+10,800
=-4(900)-7200+10,800
=3,600-7200+10800
=$7,200
The rate that maximises revenue=$7,200
Answer:
The rate that maximizes revenue is $14,000
Step-by-step explanation:
First of all, you should know that the income equation is:
R = p * n
where:
p = price per item n = number of items soldOn the other hand, if p + x means a price increase, while n - x means a decrease in the number of an item sold.
In this case, reference is made to rooms, where 60 + 2x is the increased price and 180-2x is the decrease in rooms for rent.
So:
R=(60+2x)*(180-2x)
Expressing this in another way, applying distributive property:
R=60*180+60*(-2)x+2x*180+2x*(-2)x
R=10,800+240x-4x² equation (A)
This is a quadratic equation that is graphically represented by a parabola. If a, the coefficient that accompanies the term x², has a positive value, the parabola will be oriented upwards. On the contrary, if a has a negative value, the parabola will be oriented downwards. In this case, the value of a is -4, with the parabola facing down. The vertex is a point that is part of the parabola, which has the value as ordered minimum or maximum function. In this case, since the parabola faces downward, the vertex will be its maximum value.
The value of x in the vertex is [tex]-\frac{b}{2*a}[/tex]. In this case:
a=-4b=240Replacing:
[tex]x=-\frac{240}{2*(-4)}[/tex]
Solving:
x=40
To find the rate that maximizes income you simply replace this value in equation (A)
R=10,800+240*40-4*(40)²
R=14,000
The rate that maximizes revenue is $14,000

Answer:
The correct option is;
C 90°
Step-by-step explanation:
Here we have;
Angle V = 90°
Whereby, YX and WX are tangents, and YV and WV are radii then ;
Angle Y = 90° and
Angle W = 90°
Therefore we have sum of angles V, Y, W and X given by the following relation;
V + Y + W + X = 360° (Sum of interior angles of a polygon angle)
Therefore;
90° + 90° + 90° + X = 360°
270° + X = 360
X = 360° - 270° = 90°
Hence the correct option is X = 90°.

Answer:
Step-by-step explanation:
BACD
Final answer:
The numbers from least to greatest are 2.62 (262%), 2.6 (2 3/5), and 26.2.
Explanation:
To arrange the numbers 26.2, 262%, and 2 3/5 from least to greatest in all decimal or percent forms, we need to convert them into the same form.
First, we know that 262% as a decimal is 2.62. The mixed number 2 3/5 can be converted to a decimal by dividing the numerator by the denominator and adding it to the whole number, resulting in 2 + 0.6 = 2.6.
Now we have the numbers in decimal form: 26.2, 2.62, and 2.6.
To order them from least to greatest:
2.62 (262%)2.6 (2 3/5)26.2When converting back to percent form, remember to multiply by 100. Thus, 2.62 is already given as 262%, and 2.6 becomes 260%.

To find measure of angle BAC in a right triangle, we can use the trigonometric functions cos⁻¹(6.9/12), sin⁻¹(6.9/12), and tan⁻¹(6.9/9.8), corresponding to the sides AC and CB with respect to the hypotenuse AB.
Explanation:To find the measure of angle BAC in triangle ABC where angle ACB is a right angle, we can use the trigonometric ratios involving the sides of the triangle. Given that AB is the hypotenuse, CB is the adjacent side to angle BAC, and AC is the opposite side to angle BAC, we can use the following expressions:
cos⁻¹(⅓6.9/12): This represents the cosine of angle BAC, since cosine is the ratio of the adjacent side to the hypotenuse.sin⁻¹(⅓6.9/12): This represents the sine of angle BAC, since sine is the ratio of the opposite side to the hypotenuse.tan⁻¹(⅓6.9/9.8): This represents the tangent of angle BAC, since tangent is the ratio of the opposite side to the adjacent side.Using any of these trigonometric functions, we can calculate the measure of angle BAC by inputting the ratios into a calculator that has the capability to compute the inverse trigonometric functions.
