The sum of two numbers is 50. The first number is 43 less than twice the second number. Write and solve a system of equations to find the two numbers.
Answer: 19 and 31
Step-by-step explanation: Make the first number x, the second number y.
The sum of x and y is 50: x+y=50
x is 43 less than 2y: x=2y-43
replace x in equation x+y=50 with x=2y-43: 2y-43+y=50
combine like terms: 3y-43=50
add 43 to both sides: 3y=93
divide both sides by 3: y=31
replace y in equation x+y=50 with y=31: x+31=50
subtract 43 31 from both sides: x=19
the solution to the question is the first number is 19, the second number is 31
The two numbers that sum up to 50 with one being 43 less than twice the other, we set up a system of equations, solve for one variable, and then substitute it back into the other equation, resulting in the numbers 19 and 31.
The question asks us to find two numbers whose sum is 50 and where the first number is 43 less than twice the second number. To solve this, we can create a system of equations to represent the given conditions. Let the first number be x and the second number be y.
According to the question, the sum of the two numbers is 50, which gives us our first equation:
x + y = 50 (Equation 1)
The first number x is 43 less than twice the second number y. This provides the second equation:
x = 2y - 43 (Equation 2)
We now have a simple system of two linear equations:
x + y = 50
x = 2y - 43
We can substitute the second equation into the first to solve for y:
(2y - 43) + y = 50
3y - 43 = 50
Add 43 to both sides:
3y = 93
Divide both sides by 3:
y = 31
We can now substitute y = 31 back into Equation 2 to find x:
x = 2(31) - 43
x = 62 - 43
x = 19
Therefore, the two numbers are 19 and 31.

Every Halloween, trick-or-treaters love going to Erica's house to see her spooky decorations and get some of her delicious caramel chews.
There is a proportional relationship between the number of kids in a group, x, and the total number of caramel chews Erica gives to that group, y.
x (kids) y (caramel chews)
2 6
4 12
5 15
6 18
Write an equation for the relationship between x and y.
y=
Answer:
[tex]y=3x[/tex]
Step-by-step explanation:
Let
x ----> the number of kids in a group
y ----> the total number of caramel chews Erica gives to that group
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]
Find the value of the constant of proportionality k
take a ordered pair from the data in the table and determine the value of k
For x=2, y=6 ----> [tex]k=\frac{y}{x}[/tex] ----> [tex]k=\frac{6}{2}=3\ caramels/kid[/tex]
therefore
[tex]y=3x[/tex]
In 2000, the average price of a football ticket for a Minnesota Vikings game was $48.28. During the next 20 years, the price increased an average of 6% each year. Write a model giving the annual price p (in dollars) of a ticket t in years after 2000.
[tex]y = 48.28(1.06)^t[/tex] is the model giving the annual price p (in dollars) of a ticket t in years after 2000 is found
Solution:
Given that,
In 2000, the average price of a football ticket for a Minnesota Vikings game was $48.28
During the next 20 years, the price increased an average of 6% each year
The increasing function is given by:
[tex]y = a(1+r)^t[/tex]
Where,
y is the value after t years
t is the number of years
a is the initial value
r is rate of increase in decimal
From given,
a = 48.28
[tex]r = 6 \% = \frac{6}{100} = 0.06[/tex]
Substituting the values we get,
[tex]y = 48.28(1+0.06)^t\\\\y = 48.28(1.06)^t[/tex]
Thus the model giving the annual price p (in dollars) of a ticket t in years after 2000 is found

a) [tex]\frac{dy}{dx} = \frac{1-3lnx}{x^4}[/tex]
b) [tex]\frac{dy}{dx} = \frac{-2}{3\sqrt[3]{1-x} }[/tex]
Explanation:
a) [tex]y=\frac{lnx}{x^3}[/tex]
[tex]y = \frac{lnx}{\sqrt[3]{x} }[/tex]
[tex]y = lnx. x^-3[/tex]
Differentiating the above equation in terms of x
[tex]\frac{dy}{dx} = \frac{1}{x} \times x^-3 - 3lnx\times x^-^4\\\frac{dy}{dx} = \frac{1}{x^4} - \frac{3lnx}{x^4} \\\frac{dy}{dx} = \frac{1-3lnx}{x^4} \\[/tex]
b) [tex]y = \sqrt[3]{1-x^{2} }[/tex]
Differentiating the above equation in terms of x
[tex]y = \sqrt[3]{(1-x)^{2} } \\\frac{dy}{dx} = (1-x)^\frac{2}{3} \\\frac{dy}{dx} = \frac{2}{3}\times (1-x)^\frac{-1}{3} \times -1\\\frac{dy}{dx} = \frac{-2}{3\sqrt[3]{1-x} }[/tex]
Thus,
a) [tex]\frac{dy}{dx} = \frac{1-3lnx}{x^4}[/tex]
b) [tex]\frac{dy}{dx} = \frac{-2}{3\sqrt[3]{1-x} }[/tex]

Perimeter and area for these 2 please! Give explanation! BIG POINTS
Answer: For the figure on the left {c}, the Area is 30m (squared) and the Perimeter is 46m.
For the figure on the right {d}, the Area is 32cm (squared) and the Perimeter is 34cm
Step-by-step explanation: (Please refers to the attached diagram)
We shall start with the diagram on the left. The first thing is to break it down into regular shapes, such as rectangles, squares, etc. The dotted line that runs from point C to point G divides the figure into two rectangles which are ABCG {or X} and GDEF {or Y}. Line AG measures 10m since it’s the same length as line BC. Similarly line GF measures 2m since it’s the same length as line DE. So rectangle “X” has dimensions;
L = 10, W = 1
Area of a rectangle = L x W
Area = 10 x 1
Area = 10m
Similarly rectangle Y has dimensions L= 10m and W = 2m
Hence area of rectangle “Y” is computed as
Area = L x W
Area = 10 x 2
Area = 20m
Area of the entire figure is derived as
Area of rectangle X + Area of rectangle Y, which is
10m + 20m = 30m {squared)
The perimeter of rectangle X is given as Perimeter = 2(L + W)
Perimeter = 2(10 + 1)
Perimeter = 2(11)
Perimeter = 22m
Also, perimeter of rectangle Y is derived as
Perimeter = 2(L + W)
Perimeter = 2(10+ 2)
Perimeter = 2(12)
Perimeter = 24m
Therefore the perimeter of the entire figure is derived as
Perimeter of rectangle X + perimeter of rectangle Y, which is
22m + 24m and that equals 46m
For the second figure on the right side of the page, we shall also break it down with the dotted lines that runs from point E to point G. That leaves us with rectangle ABGF {or P} and rectangle EGCD {or Q}.
Rectangle “P” has dimensions L= 4 and W = 2
Area of rectangle P = 4 x 2
Area of rectangle P = 8cm
Similarly area of rectangle Q is given as Area of Q = 8 x 3
Area of Q = 24cm
Area of the entire figure is derived as
Area of P + Area of Q,
8cm + 24cm
= 32cm {squared}
To compute the perimeter of rectangle P
Perimeter of a rectangle = 2(L + W)
Perimeter of rectangle P = 2(4 + 2)
Perimeter of rectangle P = 2(6)
Perimeter of rectangle P= 12cm
Similarly Perimeter of rectangle Q = 2(L + W)
Perimeter of rectangle Q = 2(8 + 3)
Perimeter of rectangle Q = 2(11)
Perimeter of rectangle Q = 22cm
Hence, perimeter of the entire figure is derived as perimeter of rectangle P + perimeter of rectangle Q which equals
12cm + 22cm and that equals
34cm.

What are the terms in the expression, 2 + 6 + 10b – 8a?
The terms in the expression 2 + 6 + 10b - 8a are 2, 6, 10b, and -8a, where 2 and 6 are constants, and 10b and -8a are variable terms.
Explanation:The terms in the expression 2 + 6 + 10b – 8a are 2, 6, 10b, and –8a. A term is a single mathematical expression which can be a number, a variable, or numbers and variables multiplied together. Here, the numbers 2 and 6 are called constant terms because they don’t change, 10b is a variable term which means it has a number (coefficient) and a variable (b), and similarly, –8a is a variable term with a negative coefficient and the variable a.

The fuel gauge in Nick's car says that he has 26 miles to go until his tank is empty he passed a fuel station 19 miles ago and the sign says that there is a town only 8 miles ahead if he takes a chance and drives ahead to the town and there isn't fuel station any more does he have enough fuel to go back to the last station
Answer:
No
Step-by-step explanation:
The distance from Nick's current spot to the town ahead and back to this spot is 2·8 = 16 miles. Additionally, it is 19 miles back to the gas station, so a total of 35 miles to the gas station via the town ahead. Nick does not have enough gas for that.
If there is no gas in the town ahead, there will need to be a station within 18 miles further on, or Nick will be walking 9 miles to the station he just passed.

What is the probability that a randomly chosen positive factor of 72 is less than 10?
and
A list consists of all possible three-letter arrangements formed by using the letters A, B, C, D, E, F, G, H such that the first letter is D and either the second or third letter is A. If no letter is used more than once in an arrangement and one three-letter arrangement is randomly selected from the list, what is the probability that the arrangement selected will be DCA?
Problem 1
S = sample space = set of all possible outcomes
S = set of positive factors of 72
S = {1,2,3,4,6,8,9,12,18,24,36,72}
n(S) = number of items in sample space
n(S) = 12
E = event space = set of outcomes we want to happen
E = set of factors of 72 such that they are less than 10
E = {1,2,3,4,6,8,9}
n(S) = number of items in event space
n(S) = 7
P(E) = probability get a value in set E (that is also in set S as well)
P(E) = probability we get a positive factor of 72 that is less than 10
P(E) = n(E)/n(S)
P(E) = 7/12
Answer: 7/12============================================
Problem 2

n(S) = 12
E = event space
E = {DCA}
n(E) = 1
P(E) = probability we get an item in set S that is in set E also
P(E) = probability we get DCA from set S listed above
P(E) = n(E)/n(S)
P(E) = 1/12

Which value is an output of the function? -6,-2,4,7
Without knowing the function itself, it's impossible to definitively say which of the values (-6,-2,4,7) is an output. Any of these numbers could potentially be an output depending on the function.
Explanation:In the context of this question, an output of a function refers to the result you get after substituting an input (or value from the domain) into the function. For example, if we have a function f(x) = x+2, and we input the value 3 (from our domain), our output (or range) will be 5. Unless we know the actual function, it's difficult to determine which of the listed values (-6,-2,4,7) is an output because any of these could potentially be an output depending on the function. Thus, without additional context, the statement 'Which value is an output of the function?' cannot be definitively answered.

determine whether the realtionship between the circumference of a circle and its diameter is a direct variation. if so, identify the constant of porportionatlity. justify your response
Step-by-step explanation:
Let the radius of a circle be r
The circumference of a circle is(C) [tex]=2\pi r[/tex]
[tex]=\pi d[/tex] [∵2r =d= diameter]
Therefore [tex]C = \pi d[/tex]
Since the value of [tex]\pi[/tex] is always constant. Here the diameter and the circumference are the variables.
So, [tex]C \propto d[/tex]
Therefore the constant of proportionality is [tex]\pi[/tex]
