What is the solution of x=9y and 3y - 3x =24
Answers
Answer:
Step-by-step explanation:
The solution to the system of equations `x=9y` and `3y - 3x =24` can be found by substituting the value of `x` from the first equation into the second equation. This gives us `3y - 3(9y) = 24`, which simplifies to `-24y = 24`. Solving for `y`, we get `y = -1`. Substituting this value of `y` into the first equation, we get `x = 9(-1) = -9`. So the solution to the system of equations is `(x,y) = (-9,-1)`.

The ordered pairs model an exponential function, where w is the function name and t is the input variable.
{(1, 60), (2, 240), (3, 960), (4, 3840)}
What is the function equation in sequence notation?
ANSWER: 60(4)t−1
just took the test
Answers
Answer: w(t) = 60 * 4^(t-1).
Step-by-step explanation:
The given ordered pairs model an exponential function of the form w(t) = ab^t, where w is the function name, t is the input variable, a is the initial value, and b is the growth factor.
From the first ordered pair (1, 60), we can see that the initial value a is 60. From the second and third ordered pairs (2, 240) and (3, 960), we can see that the output value is multiplied by 4 when the input value increases by 1. This means that the growth factor b is 4.
So, the function equation in sequence notation is w(t) = 60 * 4^(t-1).
The square on the right is a scaled copy of the square on the left. Identify the scale factor. Express your answer as a whole number or fraction in simplest form.
Answers
The scale factor between a square of dimensions 7 by 7 and a scaled copy of dimensions 21/2 by 21/2 is 3/2 or 1.5.
We know that the dimensions of the square on the left are 7 by 7, and the dimensions of the square on the right are 21/2 by 21/2.
To find the scale factor, we can divide the dimensions of the square on the right by the dimensions of the square on the left
scale factor = (21/2) / 7
We can simplify this fraction by dividing both the numerator and the denominator by the greatest common factor, which is 7
scale factor = (21/2) / 7 = (21/2) * (1/7) = 3/2
Therefore, the scale factor is 3/2, or 1.5.

Claude has a 10-pound package of hamburger meat and an
11.5-pound package of hamburger meat. Can he make the number of
hamburger patties shown? Choose Yes or No.
A. 87 1/4-pound hamburger patties
B. 45 1/2-pound hamburger patties
C. 30 1/2 -pound and 274-pound hamburger patties
D. 29 3/4 -pound hamburger patties
Answers
Answer: We can solve this problem by finding the total weight of the meat and then dividing by the weight of each patty to see if we can make the desired number of patties.
Let's add the weights of the two packages of meat:
10 + 11.5 = 21.5
For option A, we need 87 1/4-pound patties.
Each pound of meat will yield 4 patties of this size, so 21.5 pounds of meat will yield:
21.5 x 4 = 86 patties
Since we need 87 patties, Claude does not have enough meat for option A.
For option B, we need 45 1/2-pound patties.
Each pound of meat will yield 2 patties of this size, so 21.5 pounds of meat will yield:
21.5 x 2 = 43 patties
Since we need 45 patties, Claude does not have enough meat for option B.
For option C, we need 30 1/2-pound patties and 2 74-pound patties.
Each pound of meat will yield 2 patties of the smaller size and 1 patty of the larger size, so 21.5 pounds of meat will yield:
(21.5 x 2) + (2 x 1) = 43 + 2 = 45 patties
Since Claude only has 21.5 pounds of meat, he does not have enough for option C.
For option D, we need 29 3/4-pound patties.
Each pound of meat will yield 1.5 patties of this size, so 21.5 pounds of meat will yield:
21.5 x 1.5 = 32.25 patties
Since we only need 29.75 patties, Claude has enough meat for option D.
Therefore, the answer is Yes, Claude can make 29 3/4-pound hamburger patties.

Exactly one-year later,
(a) Mean of the ages will be 13 years and 3 months.
(b) Range of the ages will be same 2 years and 7 months.
Part (a) : To find the mean of the ages of the same group of students exactly one year later, we add one year to each student's age and find the new mean.
New mean is : 12 years and 3 months + 1 year = 13 years and 3 months;
So the mean of the ages of the same group of students exactly one year later is 13 years and 3 months.
Part (b) : The range of their ages would still be 2 years and 7 months because we are adding the same amount to all of their ages, the difference between the youngest and oldest member of the group would remain the same.

Therefore , the solution of the given problem of unitary method comes out to be 50 tyre rotations, you will have covered around 376.99 inches (or about 31.41 feet).
What is a unitary method?The well-known simple approach, real variables, and any crucial elements from the very initial And specialised inquiry can all be used to finish the work. Customers may then be given another chance to try the product in response. If not, significant impacts on our understanding of algorithms will vanish.
Here,
The circumference of the circle the bike tyre forms is equal to the distance travelled in one rotation of the tyre. The following formula determines a circle's circumference:
=> C = 2πr
where the mathematical constant is roughly equivalent to 3.14159 and r is the circle's radius.
Your bicycle tyre's radius in this instance is 12 inches. The tyre's circumference is as follows:
=> C = 2π(12) = 24π inches
You may easily calculate how far you will travel after 50 spins by multiplying the tyre's circumference by the number of turns:
=> Covered distance: 50 × 24π ≈ 376.99 inches

The calculated distance between the tree and the zip line is 9.21 units
Evaluating the distance between the tree and the zip lineFrom the question, we have the following parameters that can be used in our computation:
y = -6/7x + 7
This represents the zip line
Convert the equation to standard form
This gives
7y = -6x + 49
So, we have
6x + 7y - 49 = 0
This means that
A = 6, B = 7 and C = -49
From the point (6, 14), we have
x = 6 and y = 14
The distance between the tree and the zip line is then calculated as
[tex]d = \frac{|ax + by + c|}{\sqrt{a^2 + b^2}}[/tex]
By substitution, we have
[tex]d = \frac{|6 * 6 + 7 * 14 - 49|}{\sqrt{6^2 + 7^2}}[/tex]

Using trigonometry and the Pythagorean theorem, the length of the hypotenuse AC is found to be 3.5 cm, and using the Pythagorean theorem again, the length of BC is found to be approximately 1.75 cm.
Using trigonometry and the given angle and side length information, we can solve for the length of side BC (x).
We know that
sin(A) = opposite/hypotenuse
sin(30) = AC/7
AC = 7 × sin(30)
AC = 3.5 cm
Using the Pythagorean theorem, we have
BC² = AC² - AB²
BC² = (3.5)² - (7)² sin²(30)
BC² = 3.0625
BC = √3.0625
BC = 1.75 cm (rounded to two decimal places)

Answers
The ball reaches a height of 40 meters at approximately 3.38 seconds after it is kicked.
To determine if the ball reaches a height of 40 meters, we can substitute h(t) = 40 into the equation and solve for t.
40 = -2t² + 4t + 27
Rearranging the terms, we get:
2t² - 4t - 13 = 0
We can solve for t using the quadratic formula:
t = [4 ± √(4² - 4(2)(-13))]/(2(2))
t = [4 ± √(176)]/4
t ≈ 3.38 or t ≈ -0.88
Since time cannot be negative, we can discard the negative solution. Therefore, the ball reaches a height of 40 meters at approximately 3.38 seconds after it is kicked.
