Can someone plz help and plz explain your answer.
Questions:
Find the area. Use 3.14 for the value of pi. Round your answer to the nearest tenth. diameter = 18 km
The circumference of a circular garden is 128.74 feet. What is the diameter of the garden? Use 3.14 and do not round your answer.
Answer:
41 feet
Step-by-step explanation:
For a radius r, the circumference is [tex]2\pi r[/tex] and the diameter is [tex]2r[/tex], so to get diameter, we can just divide the circumference by pi and we get the answer. Using 3.14 for pi we get:
[tex]127.74 / 3.14 = 41[/tex]

Answer:
[tex]92\ yd^2[/tex]
Step-by-step explanation:
The given figure is a trapezoid, the formula for finding the area of a trapezoid is the following,
[tex]A=\frac{h(b_1+b_2)}{2}[/tex]
Where (h) is the height of the figure, and ([tex]b_1[/tex]) and ([tex]b_2[/tex]) are the bases. It is given that the height is (8) and ([tex]b_1[/tex]) is (8). The value of ([tex]b_2[/tex]) can be found by adding the value of ([tex]b_1[/tex]) to the "overhang" that ([tex]b_2[/tex]) has over ([tex]b_1[/tex]). Thus, ([tex]b_2[/tex]) is ([tex]8+7[/tex]) or rather ([tex]15[/tex]). Now substitute the values into the equation and solve for the area of the trapezoid,
[tex]A=\frac{8(8+15)}{2}[/tex]
[tex]=\frac{8(23)}{2}[/tex]
[tex]=4(23)[/tex]
[tex]=92[/tex]

An exponential function has the equation y = (0.5)^x-1. Four points from a different function as shown in the table. For what values of x will two functions be equal?
Answer: f(x) = 64 * (3/4)^x
Step-by-step explanation: f(x)=ab^x
When x=0 f(x) = 64
64 = ab^0
b^0 =1 so
64 =a
f(x)=64 b^x
When x=1 f(x) = 48
48 = 64 *b
Divide by 64
48/64 =b
6/8 =b
3/4 =b
f(x) = 64 * (3/4)^x
please help simplify this!
Answer:
Step-by-step explanation:
[tex]\frac{16}{x^{12}}[/tex].
We get this by distributing the 4 into each term. 2^4 is 16 and (x^-3)^4 is x^-12 which is equal to 1/x^12
Answer:
16/x^12
Step-by-step explanation:
Many games involve chance and they usually involved either dice or cards. For this activity, we will look at a common game called 7‐11 where two dice are rolled. If the roll adds up to 7 or 11, the player wins. If the roll adds up to 2, 3, or 12, the player loses. If there is any other sum, it is a draw (no winner or loser). Use this two‐dice roll scenario to complete the problems below.
1. Create a tree diagram to determine all the possible outcomes of rolling two dice.

Answer:
5(2c - 3) = 3(3c - 5)
=> 10c - 15 = 9c - 15c
=> 10c+15c = 9c + 15c
=> 25c = 24
=> c = 24/25
Answer:
c=0
Step-by-step explanation:
Remove the parentheses
10c - 15 = 9c - 15
10c = 9c
Move the variable to the left
10c-9c=0
Collect like terms
then solve it and you'll get c=0

A frog leaps 2 feet. The highest point in the jump is 6 inches. Assume the frog starts at (0, 0). Write a quadratic function in vertex form for the path of the jump. Specify the units you use.
Answer:
[tex]\displaystyle f(x)=-\frac{1}{24}\left(x-12\right)^2+6[/tex]
Where f(x) models the height, in inches, of the frog's leap after it had leapt x inches.
Step-by-step explanation:
We are given that a frog leaps two feet, with the highest point in the jump being six inches.
Assuming the frog starts at (0,0), we want to find a quadratic function in vertex form for the path of the jump.
First, we will convert the length of the jump to inches. Two feet is equivalent to 24 inches.
Next, since the frog started at (0, 0), in order to jump a length of 24 inches, it must have ended at (0, 24). These two points will also be our two roots: x = 0 and x = 24. We can use the factored form of a quadratic:
[tex]f(x)=a(x-p)(x-q)[/tex]
Where p and q are the roots.
Substitute in the roots:
[tex]f(x)=a(x-0)(x-24)=ax(x-24)[/tex]
Now, since the frog reached a maximum height of six inches, the y-coordinate of the function at its vertex point is 6.
Since a parabola is symmetrical along its axis of symmetry, the axis of symmetry is always halfway between the two roots.
Therefore, the x-coordinate of our vertex is:
[tex]\displaystyle x=\frac{24-0}{2}=12[/tex]
So, when x = 12, f(x) = 6. Substitute:
[tex]6=a(12)(12-24)[/tex]
Solve for a:
[tex]\displaystyle- 144a=6\Rightarrow a=-\frac{1}{24}[/tex]
Therefore, our function is:
[tex]\displaystyle f(x)=-\frac{1}{24}x(x-24)[/tex]
Now, we can place this into vertex form:
[tex]\displaystyle f(x)=a(x-h)^2+k[/tex]
Where a is the leading coefficient and (h, k) is the vertex.
Our leading coefficient is -1/24, and the vertex is (12, 6). Hence, our function is:
[tex]\displaystyle f(x)=-\frac{1}{24}\left(x-12\right)^2+6[/tex]
Where f(x) models the height, in inches, of the frog's leap after it had leapt x inches.

Explain how to solve the equation and how to check the solution. 40 = 8y
answer is
Use the inverse operation to isolate the variable. Undo multiplication by dividing by 8 on both sides of the equation. Simplify by completing the divisions, 40 ÷ 8 = 5, and 8 ÷ 8 = 1. The solution is y = 5. Check the solution by substituting 5 for y in the original equation, and then simplify. 8 × 5 = 40 and 40 = 40 is a true statement, so 5 is the solution.
Answer:
U already know the answer, then why ask?? I'll explain it once again, tho :)

Francisco is playing a game with 3 green, 2 yellow, 4 red, and 3 black marbles in a bag. He has calculated the probability of drawing a yellow marble, not replacing it, and then drawing a red marble. Explain the error in his solution.
(StartFraction 2 over 12 EndFraction) (StartFraction 4 over 12 EndFraction) = StartFraction 8 over 144 EndFraction
pls help!
Answer:
mag sagot ka module mo yan
Answer:
The probability is not 4/12 for the red marble, but 4/11
Step-by-step explanation:
Francisco calculated to probability of drawing a yellow marble correctly, but since he isn't replacing it, the amount of marbles in the bag is not 12, but 11. Since there are 4 red marbles, the probability is 4/11
Vanessa and Dominic are buying chicken for a barbecue. The table shows prices for different packages of chicken.
Vanessa says the constant of proportionality is 4. Dominic says it is .
Who is correct? Explain your reasoning.
A. Vanessa is correct because 6 – 2 = 4.
B. Dominic is correct because is the smallest number.
C. Dominic is correct because the quotient when dividing the values in the top row by the values in the bottom row is always .
D. Vanessa is correct because the quotient when dividing the values in the bottom row by the values in the top row is always 4.
24-1 = 23
6-1/4 = 5 3/4
23/5 3/4 = 4
The constant is 4, so Vanessa is correct
The answer is:
D. Vanessa is correct because the quotient when dividing the values in the bottom row by the values in the top row is always 4.

Answer: Should be 130
Step-by-step explanation:
A is 80 180-80 is 100. Since it’s an isosceles you can divide by 2 and the two angles would be the same. 100/2 is 50 because two remote interior angles is equal to the exterior angle, 50+80 is 130, d is 130
Answer:
Angle D is 130 degrees
Step-by-step explanation:
180-80=50
Angles b and c are the same and will both be 50 degrees.
The angle of a straight line is 180 degrees.
Since angle c is 50 degrees, then the other angle (d) will have to be 130, so that together the total of the two is 180 degrees.
I hope this helps :)

The kite shown below is translated 8 units to the right and 1 unit up.
Which property will remain the same?
A.
the coordinates of the x-intercept
B.
the coordinates of the vertices
C.
the perimeter of the kite
D.
the angle between the top vertex and the origin
Answer:
C. The perimeter of the kiteStep-by-step explanation:
Answer A is not correct because if the kite moves both right and up, the x and y coordinates will change
Answer B is the same as answer A. The kite moved so the coordinates will change.
Answer D is also the same. If the kite moves both on the x and y axis, any angle and distance will change.
Answer C is correct. Since C does not rely on the coordinates, it will always be the same. The position of a shape does not change it´s perimeter.
