Answer:
a) 9x + 7y = 279
3x + 5y = 135
b) X (Weight of each large box) = 18.75 kilograms
Y (Weight of each small box) = 15.75 kilograms
Step-by-step explanation:
Let's assume:
X is weight of each large box
Y is weight of each small box
First, multiply the opposite number to get the same value of y:
9x + 7y = 279 ..... ×5
3x + 5y = 135 ...... ×7
Second, here comes the outcome of the multiplication from both side:
45x + 35y = 1,395
21x + 35y = 945
24x = 450
x = 18.75 kg
if x = 18.75, then:
3x + 5y = 135
3×(18.75) + 5y = 135
56.25 + 5y = 135
5y = 135 - 56.25
5y = 78.75
y = 15.75 kg
If you try to input the x and y value into the part a) equation, then you will get the same total weight for first and second delivery respectively.
Hope it helps. Thanks!

A=m/360pi times radius to the power of 2. Given the measure m of the angle and the radius r of a circle.
Find the measure of the angle if the area of the sector is 5 square centimeters and the radius is 2 centimeters. Round your answer to the nearest tenth.
\(A=\dfrac{m}{360}*\pi r^2\)
A = area of sectorm = measure of angle in degreesr = radiusSolving the Question
We're given:
A = 5 cm²r = 2 cmm = ?Plug the given information into the equation and solve for m:
\(A=\dfrac{m}{360}*\pi r^2\\\\5=\dfrac{m}{360}*\pi (2)^2\\\\5=\dfrac{m}{360}*4\pi \\\\\dfrac{5}{4\pi}=\dfrac{m}{360}\\\\m=\dfrac{5*360}{4\pi}\\\\m=143.2\)
Answerm = 143.2°
Answer:
m = 143.2 degrees.

10 = 0.5n + 1.5
0.5n + 1.5 = 10
0.5n x 10 + 1.5 x 10 = 10 x 10
5n + 15 = 100
5n + 15 - 15 = 100 - 15

Answer:
The first table matches with the last equation.
The second table matches with the first equation.
The last table matches with the second equation.
Step-by-step explanation:
What I did was plug in the number in the x section for each table to see if the result of x times the number such as 4 resulted in the same number, y, that was paired with the x number based on the table.
Ex: Using table 1,
y=4x
y=4(2) --> I substituted the x for row 1 x in table 1
y=8
Check:
The first table shows that for row 1, the y was 8 so our match was correct.

Answer:
Refer to the explanation
Step-by-step explanation:
Well, I'm not too sure whether or not there was supposed to be a dollar amount for the cost of a Museum Ticket, but this is what I came up with:
y = the total amount of the ticket
x = the number of family members
a = processing fee per ticket
b = cost of ticket
y = b(x) + a
please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

How can I find the cube root of 64?
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

William is a very busy professional DJ. Last year, he worked at 10-anniversary parties and 26 other events.
What is the probability that one of the events William worked on last year, selected at random, was an anniversary party?
Write your answer as a fraction or whole number.
Answer:
hello
Step-by-step explanation:
The required probability that William worked on last year was an anniversary party is 1/ 36.
As mentioned in the quesiton,
William is a very busy professional DJ. Last year, he worked at 10-anniversary parties and 26 other events.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Total sample space = 26 + 10 = 36
Number of favorable outcomes = 1
the probability that William worked on last year is was an anniversary party,
= Favorable outcome/sample space
= 1 / 36
Thus, the required probability that William worked last year is 1/ 36.
