sqare root 10^2-2=8
y=100
Answer:
y = 100
Step-by-step explanation:
Assuming you mean sqrt(y) - 2 = 8
Add 2 to each side
sqrt(y) - 2+2 = 8+2
sqrt(y) = 10
Square each side
y = 10^2
y = 100

Which statement is correct about the system of linear equations graphed below? On a coordinate plane, a line with negative slope goes through (0, 3) and (4, 2). A line with positive slope goes through (0, negative 4) and (4, negative 2). The system of equations has one solution because the lines will eventually intersect. The system of equations has one solution because the lines will never intersect. The system of equations does not have one solution because the lines will eventually intersect. The system of equations does not have one solution because the lines will never intersect.
Answer:
the answer is A. The system of equations has one solution because the lines will eventually intersect
Step-by-step explanation: because as the line goes on it will intercect once and if it has only one point of intercect its one solution
The system of equations has one solution because the lines will eventually intersect.
Which statement is true?
We know that for a system of equations, the solutions are the points where the graphs of the equations do intercept.
Also, remember that two lines always intercept if they have different slopes (parallel lines have the same slope and different y-intercept).
In this particular case, we know that one line has a negative slope and the other has a positive slope, so the lines are not parallel. This means that the lines will intercept, so the system has one solution.
With that in mind, the correct statement is "The system of equations has one solution because the lines will eventually intersect."

Over 44% of the 30 students in a class read a
book last month. What are the possible numbers of students in the class
who read a book last month? Justify your answer.
Answer:
I got 13.2 but you could probably round it to 13.
Step-by-step explanation:
44 percent *30 =
(44:100)*30 =
(44*30):100 =
1320:100 = 13.2
The possible number of students in the class who read a book last month is 13 students
Let the total number of students that read the book last month be xIf over 44% of the 30 students in a class read a book last month, hence;
44% of 30 = x
0.44 * 30 = x
Simplifying the expression
x = 13.2
Hence the possible number of students in the class who read a book last month is 13 students

Gia is running for school president. Her best friend designed a rectangular button that measures 2.5 inches by 2 inches. Gina liked the button so much she produced a campaign poster, which measures 5 feet by 4 feet. What scale factor did Gina use to make the poster from the button?
Answer:
24:1
Step-by-step explanation:
To find the scale used to make the poster we just need to find the ratio between the poster and the button, and we do this by dividing the length and width of the poster by the length and width of the button.
So, we have that:
ratio = length poster / length button = 5 feet / 2.5 inches = 2 feet to 1 inch
ratio = width poster / width button = 4 feet / 2 inches = 2 feet to 1 inch
if 1 foot is equal 12 inches, we have a ratio of 2*12 inches to 1 inch = 24 to 1 (24:1)

What is the probability of tossing 3 heads in a row when flipping a coin?
Answer:
0.125
Step-by-step explanation:
Assuming the coin is fair (most coins are not completely fair) and that the person flipping is not able to control the tosses (some people can) then the chance is 0.125. On each flip, the chance is 1/2. The combination is simply the product of three tosses, since the events are independent.

Complete question:
A veterinarian surveys her clients and finds that 32 percent of the households have dogs, 25 percent have cats, and 11 percent have both dogs and cats. Let event C be choosing a client who has cats and let event D be choosing a client who has dogs. Which statements are true? Check all that apply.
1. P(C | D) = 0.78
2. P(D | C) = 0.44
3. P(C ∩ D) = 0.11
4. P(C ∩ D) = P(D ∩ C)
5. P(C | D) = P(D | C)
Answer:
3. P(C ∩ D) = 0.11
4. P(C ∩ D) = P(D ∩ C)
Step-by-step explanation:
Clients that have Cats = P(C) = 25% = 0.25
Clients that have Dogs = P(D) = 32% = 0.32
The number of Clients that have Dogs and Cats = P(D ∩ C) = 11% = 0.11
Sets of data in mathematics are governed by laws which include Distributive law, Commutative law, Associative law, Identity law e.t.c.
The commutative law of sets states that :
A ∩ B = B ∩ A
A ∪ B = B ∪ A
Therefore, based on the commutative law of sets, Option 4 " P(C ∩ D) = P(D ∩ C) " is correct.
Since we are told in the question above that the number of Clients that have Dogs and Cats = P(D ∩ C) = 11% = 0.11 and based on the commutative law that says
P(C ∩ D) = P(D ∩ C)
Therefore, Option 3 " P(C ∩ D) = 0.11"
is correct as well.

Cylinder A has a base of 3 and height of 3 cylinder be has the base of 2 and the height of 4. What is the ratio of the volume of cylinder A to the volume of cylinder B?
Answer:
1.6875
Step-by-step explanation:
For cylinder A, the base = diameter = 3, the height of the base is 3.
The radius of cylinder A (r) = diameter / 2 = 3/2 = 1.5
The volume of a cylinder is given by the equation:
Volume (v) = πr²h
Therefore volume of cylinder A = πr²h = π × 1.5² × 3 = 6.75π
For cylinder B, the base = diameter = 2, the height of the base is 4.
The radius of cylinder B (r) = diameter / 2 = 2/2 = 1
The volume of a cylinder is given by the equation:
Volume (v) = πr²h
Therefore volume of cylinder A = πr²h = π × 1² × 4 = 4π
The ratio of the volume of cylinder A to the volume of cylinder B = volume of cylinder A / volume of cylinder B = 6.75π / 4π = 1.6875

Describe the transformations from, y=x2, the original parent function

Going from y = x^2 to y = (x-6)^2 has the graph shifted 6 units to the right
The replacement of "x" with "x-6" shifts the xy axis 6 units to the left. All new inputs are 6 units smaller than before. If you shift the xy axis 6 units to the left and keep the parabola still, then it gives the illusion the parabola moved 6 units to the right.

Mr. Sanford left half of his fortune to April, his daughter. He left of the remaining half to his uncle Jed. He left half of the remaining half to his favorite charity. He left the remaining $30,000 to the local animal shelter. What was the total amount of Mr. Sanford’s fortune?
9514 1404 393
Answer:
$240,000
Step-by-step explanation:
Let f represent Mr. Sanford's fortune.
1/2x went to April, so 1/2x remains.
1/2(1/2x) = 1/4x went to Jed, so 1/2x -1/4x = 1/4x remains.
1/2(1/4x) = 1/8x went to charity, so 1/4x -1/8x = 1/8x remains.
That remaining 1/8x was $30,000, so the total amount of Mr. Sanford's fortune was ...
8 × $30,000 = $240,000

Answer:
Step-by-step explanation:
y = x + 2 and y = x + 7 are parallel straight lines which have the same slope, 1. The graph of y = x + 2 becomes the graph of y = x + 7 if we translate it (graph of y = x + 2) up 5 units.
Write the equation x2=7x in standard form.
Answer:
i believe it's x2-7x=0
Step-by-step explanation:
To write the equation x^2 = 7x in standard form, subtract 7x from both sides and rearrange the terms in descending order of exponents.
Explanation:The equation x^2 = 7x is a quadratic equation. To write it in standard form, we need to move all the terms to one side and set the equation equal to zero.
Subtracting 7x from both sides, we get x^2 - 7x = 0.
Next, we rearrange the terms in descending order of exponents: x^2 - 7x = 0.

How many seconds will it take the object to reach the ground?
It will take approximately 5.05 seconds for the object to reach the ground.
Explanation:In order to determine how long it will take an object to reach the ground, we need to consider the height from which the object is dropped. Let's assume the height is 75.0 m.
The time it takes for an object to fall to the ground can be calculated using the equation t = sqrt(2h/g), where t is the time, h is the height, and g is the acceleration due to gravity (approximately 9.8 m/s^2).
Plugging in the values, t = sqrt(2 * 75.0 / 9.8) = sqrt(150 / 9.8) ≈ 5.05 seconds.
Therefore, it will take approximately 5.05 seconds for the object to reach the ground.
