A dart hits the board. What is the probability
that it will hit in Region II, as a decimal to the
nearest tenth?
Answers
Answer: The probability is 0.5
Step-by-step explanation:
The probability will be equal to the quotient between the area of region II, and the total area of the board (supposing that the probability of hitting in any place is equal)
The total area of the figure is equal to
Area = (15' + 35')*(8' + 20') = 50'*28' = 1400 in^2
Now, the area of region II is:
Region II = 20'*35' = 700
Then the probability is:
P = 700/1400 = 1/2 = 0.5

On a certain hot summer's day, 163 people used the public swimming pool. The daily prices are $ 1.50 for children and $ 2.50 for adults. The receipts for admission totaled $ 312.50 . How many children and how many adults swam at the public pool that day?
Answers
Answer: 95 children, 68 adults
Step-by-step explanation:
Let the number of children be y
Let the number of adults be z
The following equation can be gotten from the question:
y + z = 163 ...... equation i
1.5y + 2.5z = 312.5 ....... equation ii
Multiply equation I by 1.5
Multiply equation ii by 1
1.5y + 1.5z = 244.5 ......... equation iii
1.5y + 2.5z = 312.5 ........ equation iv
Then subtract equation iv from iii
-z = -68
z = 68
From equation I
y + z = 163
y = 163 - 68
= 95
95 children and 68 adults swam.

B. an = -8n + 6

Step-by-step explanation:
The terms in the sequence have a common difference d between consecutive terms, that is
d = - 4 - 2 = - 10 - ( - 4) = - 16 - (- 10) = - 22 - (- 16) = - 6
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = - 6, thus

What is the perimeter of the given composite figure
Answers
Answer:
The perimeter of the given composite figure is:
106 ydStep-by-step explanation:
The perimeter is defined as the sum of the sides in a figure, therefore, what you should do in this exercise is to add all the yards of the sides of the compound figure, however, you should notice that there are two sides of which They do not give you the measurement and you must identify it based on the sides that do have it, which would be:
Vertical line measurement = (19 + 4-17) yards Vertical line measurement = 6 yardsIn the previous case, the two measures on the other side that are complete are used, which are 19 yards and 4 yards respectively, then the measurement that is on our same side (17 yards) is subtracted and thus we obtain the value of the vertical line that it did not have, now that of the horizontal line:
Horizontal line measurement = (30-12-15) yards Horizontal line measurement = 3 yardsIn this case, something similar was done, the total measurement of the base was taken and the measurements of the upper zone were subtracted, with which the measurement of the remaining zone was found.
All the measures are added together:
The perimeter of the figure = 30 yd + 17 yd + 12 yd + 6 yd + 15 yd + 4 yd + 3 yd + 19 yd = 106 ydAnswer:

Graph the equation
y=2(x+1)(x-1)
Answers
To graph the equation y = 2(x+1)(x-1), we can start by finding the x-intercepts and y-intercept of the equation.
To find the x-intercepts, we set y = 0 and solve for x:
0 = 2(x+1)(x-1)
0 = 2(x^2 - 1)
0 = 2(x+1)(x-1)
So, the x-intercepts are -1 and 1.
To find the y-intercept, we set x = 0 and solve for y:
y = 2(0+1)(0-1)
y = -2
So, the y-intercept is -2.
Now, we can plot the intercepts on the coordinate plane and sketch the graph of the equation. Since the equation is a quadratic function, the graph will be a parabola.
The x-intercepts are -1 and 1, so we can plot these points on the x-axis. The y-intercept is -2, so we can plot this point on the y-axis.
Next, we can plot a few additional points to help us sketch the graph. For example, we can choose x = -2, -0.5, 0.5, and 2, and find the corresponding y-values:
When x = -2, y = 2(-2+1)(-2-1) = 6
When x = -0.5, y = 2(-0.5+1)(-0.5-1) = 1.5
When x = 0.5, y = 2(0.5+1)(0.5-1) = -1.5
When x = 2, y = 2(2+1)(2-1) = 6
Now, we can plot these points and sketch the graph of the equation, which is a parabola that opens upwards and passes through the points (-2, 6), (-1, 0), (0, -2), (1, 0), and (2, 6).
The graph of the equation y = 2(x+1)(x-1) is shown below:
Graph of y = 2(x+1)(x-1)
Therefore, this is the graph of the equation y = 2(x+1)(x-1).

The area of a triangle is given by
A = 1/2 bh where b is the base and h is the height
The base length is 6 and the height is 6
A = 1/2 (6) * 6
A =18
Answer:
B. 18 units²
Step-by-step explanation:
You find the area of the triangle with the dotted lines first:
[tex]\frac{1}{2}[/tex]*b*h
[tex]\frac{1}{2}[/tex]*9*6=
27
The area of the triangle including the dotted lines is 27 units²
Now we need to find the area of the small dotted triangle using the solid line triangle as a hypotenuse.
[tex]\frac{1}{2}[/tex]*b*h
[tex]\frac{1}{2}[/tex]*3*6=
9
The area of the small dotted triangle is 9 units²
To find the area of the solid lined triangle, you need to subtract the area of the small dotted line triangle (9 units²) from the triangle with the dotted lines (27 units²) which is:
27-9=18
The solid lined triangle is 18 units²

Answers
Answer: (x, y) —> (-x, y)
Step-by-step explanation:
This is because the translation rule for reflection across the y-axis is (x, y) —> (-x, y)
(x, y) --> (-x , y)
Step-by-step explanation:
When reflecting across the y-axis, you will want to switch the sign of the x-coordinate. If the x-coordinate is positive, you will want to switch it to negative and vice versa.
Examples:
(3,5) --> (-3,5)
(-6,-2) --> (6,-2)

If you are going to reflect across the x-axis, you will change the y-coordinate, so it is the opposite of reflecting across the y-axis.

Answer:
$33.18
Step-by-step explanation:
$33.18 is the answer because...
Step one first we have the money in the cash register of $82.92. Unfortunately she has to pay a phone bill of $78.24 so we subtract 82.92 and 78.24 which leaves the person with $4.68.Step two so she has $4.68 but now she gets an outstanding $125 paycheck. So we add $4.68 and $125 to get $129.68 as her new balance.Now the person's balance is $129.68 it says in the question she debited $40 from the ATM. So we subtract $129.68 and $40 to get $89.68.Step four she also had to pay $56.50 for the persons tennis lessons so we subtract $89.68 and $56.50 to get our final answer of $33.18Hope this helped :)The current balance is calculated by starting with the initial balance of $82.92 and then subtracting debits and adding credits from various transactions. After all adjustments, the current account balance is $33.18.
To calculate the current balance, we'll start with the first number under Balance and adjust it based on the recorded transactions.
Start with the initial balance: $82.92
Subtract the debit for the phone bill: $82.92 - $78.24 = $4.68
Add the deposit from the paycheck: $4.68 + $125.00 = $129.68
Subtract the ATM debit: $129.68 - $40.00 = $89.68
Finally, subtract the debit for tennis lessons: $89.68 - $56.50 = $33.18
Therefore, the current balance is $33.18.

What is the distance of Line S T?
7 km
StartFraction 128 Over 11 EndFraction km
22 km
49.5 km
Answers
The answer is C = 22km
Final answer:
To determine the distance of line ST, we use the fact that triangles PQR and SRT are similar, which allows us to set up a proportion with the given side lengths. Solving this proportion reveals that the length of ST is 22 kilometers.
Explanation:
To find the distance of line ST, we need to recognize that if lines PQ and ST are parallel (PQ | | ST) and we are given the lengths of the sides PQ and PR in triangle PQR and side RT in triangle SRT, we can infer that triangles PQR and SRT are similar by the Angle-Side-Angle (ASA) postulate since they share angle P (or R in triangle SRT) and have proportional corresponding sides.
Using the lengths PQ = 16 kilometers and PR = 24 kilometers from triangle PQR and RT = 33 kilometers from triangle SRT, we can set up a proportion to solve for the unknown length ST.
The proportion based on the similarity of triangles is:
PQ/PR = ST/RT
Substituting the given values, we get:
16/24 = ST/33
Solving for ST, we multiply both sides by 33:
ST = 33 * (16/24) = 22 kilometers.
Therefore, the distance of line ST is 22 kilometers.
