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.

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]
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

Fill in the table for this input-output rule:
Answer:
1. 1
2. 2
3. -3
4. 51
Step-by-step explanation:
To do this, in each input number (I will represent the number as x), you have to do the number in the input number, x. You have to divide x by 2, then add 1.
x/2 + 1 would be the answer (this is an example).

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.
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.
The radius is 2.1. What is the area of this circle? Round your answer to the nearest tenth. Use 3.14 for pi.
Answer:
Hey!
The area would be 13.85Step-by-step explanation:-
Area of a circle's equation is π[tex]r^{2}[/tex] (pi [tex]r^{2}[/tex])
Since the radius is 2.1 and value of pi is 3.14cm,
area is
[tex]2.1^{2}[/tex] x 3.14
4.41 x 3.14
= 13.85
The area of this circle is 13.6.
What is the area of the circle?Area of a circle is the region occupied by the circle in a two-dimensional plane.
The area of the circle is;
[tex]\rm Area \ of \ circle=\pi r^2\\\\Where\ r =radius[/tex]
The radius is 2.1.
Substitute all the values in the formula
[tex]\rm Area \ of \ circle=\pi r^2\\\\ Area \ of \ circle=3.14 \times 2.1^2\\\\ Area \ of \ circle=13.6[/tex]
Hence, the area of this circle is 13.6.

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

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]

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

Answer:
a and c
Step-by-step explanation:
so we know that -2 is the greatest number in this inequality and with that, the 'equation' would look like this-
x<-2
now let us solve a-d-
0.25-2.50=-2.50
-4.25-(-2.75)=-1.5
-3.25-1.75=-5
-4.50-(-5.25)=0.75
**with negative numbers the 'smaller' the number is the greater it actually is ex. -2.50<-1** it works this way because the 'larger' the number gets the further away it becomes from 0 or whole numbers making it smaller than the negative numbers closer to zero such as -1**
hopefully, that makes sense
now let us see which equations fit our inequality- **we'll let the bolded ones mean that they fit the inequality**
a)-2.50<-2
b)-1.5<-2
c)-5<-2
d)0.75<-2
good luck :)
i hope this helps
