A company orders 23 boxed lunches from a deli for $201.25. Assume each boxed lunch is the same price. If c represents the total cost in dollars and cents of the lunch order for any number, b, of boxed lunches ordered, write a proportional equation for c in terms of b that matches the context.
(I HAVE ONLY ONE ATTEMPT,PLEASE HELP)
Answers
Answer:
c = 8.75b
Step-by-step explanation:
Since each box costs the same,
The cost of one box = Total cost of 23 boxes ÷ 23
= 201.25 / 23 = 8.75
For b boxes, the total cost would be $8.75b
This should be equal to c which is the variable used to represent the total cost
So the equation is
c = 8.75b

Show that the set {-1, 0, 1} is closed under multiplication
Answers
The statement that the set {-1, 0, 1} is closed under multiplication, is true and can be proven.
As per the question statement, we are provided with a set {-1, 0, 1}.
We are required to determine if the above mentioned set is closed under multiplication or not.
To solve this question, we simply need to verify if the products of every distinct combination of 2 elements from the concerned set, belongs to the set itself or not, i.e., if we take any two elements "x" and "y", say, from the set "Z", then, [(x*y) ∈ Z].
Here, [tex][(-1)*0]=0[/tex], i.e., belongs to set {-1, 0, 1}.
[tex][(-1)*1]=(-1)[/tex] i.e., also belongs to set {-1, 0, 1}.
Finally, [tex](0*1)=0[/tex] i.e., also belongs to set {-1, 0, 1}.
Since, the products of every distinct combination of 2 elements from the concerned set, belongs to the set itself, the statement that the set
{-1, 0, 1} is closed under multiplication, is true and proven.

In how many weeks will the number of infected people reach 568?
Answers
The number of infected people will reach 568 in approximately 4 weeks
Linear equation and functionExponential equations are inverse of logarithmic equation and are represented by the equation below:
y = ab^x
where
a is the base value and x is the exponent
Given the equation that shows the number of infected people from an outbreak of the measles as:
y = 4(6)^t
If the number of infected people reach 568, hence;
568 = 4(6)^t
568/4 = 4(6)^t/4
6^t = 568/4
6^t = 142
Take the natural logarithm of both sides
ln(6^t) = ln142
t = ln142/ln6
t = 4.37

In a given bag of M & M's, 16 were yellow, 15 were green, 21 were brown, and 11 were red.
How many M&M's were in the bag?
What fraction were yellow?

What fraction were brown?
What fraction were red?
Answers
Answer:
There are 63 M&M's in the bag when all of them are added together.
16 out of 63 (16/63) were yellow.
5 out of 21 (5/21) were green. This answer is simplified. The original is 15/63.
1 out of 3 (1/3) were brown. This answer is simplified. The original is 21/63.
11 out of 63 (11/63) were red.
Tip:
To find the fraction of something, put the total on the bottom and the wanted portion on the top.
Example: 5 yellow and 10 red birds were in a cage. Which fraction were yellow?
We put the total of birds (5+10 = 15) on the bottom and the portion wanted ("5 yellow") on the top. The fraction is 5 out of 15 (5/15). This fraction can be simplified because 5 goes into 15 three times (5 x 3 = 15), so divide the fraction 5/15 by 3 to get 1/3. (5 goes into 5 one time.)
How much interest would 2000 earn, with simple interest, in two years at the rate of 1.2%?
Answers
The simple interest, in two years at the rate of 1.2% is 880
In this case, we must calculate how much interest 2000 would earn compounded yearly over two years at a rate of 1.2.
I = 880 in interest earned
Annually, the system may be evaluated in terms of simple interest.
A = P(rt) for the first year, where r = 1.2 and t = 1.
Therefore;
A = 2000(1.2×1).
A = 2400.
As a result, the revised Principal amount for the second year is 2400.
As a result, A' = 2400 (1.21).
A' = 2880.
As a result, the sum owing after two years is 2880.
However, because the initial principal is $2,000,
The interest is defined as I = A' - P, or I = 2880 - 2000.
I = 880 as a result of interest.
Simple interest is computed as S.I. = P R T, where P = Principal, R = Annual Rate of Interest in %, and T = Time, commonly expressed as the number of years. The interest rate is expressed as a percentage r% and is written as r/100.
The principle is the money borrowed from the bank or invested at the outset. P represents the principal.
Rate: The rate of interest at which the principle amount is handed to someone for a specific period of time; the rate of interest can be 5%, 10%, or 13%, for example. R represents the interest rate.
Time is the length of time for which the primary amount is supplied to someone. T represents time.

How to solve for the amount of moneyWe would first have to define x to be the point where the money that they have would be equal

Sean would have $20 + $2x
Max would have $5x
When both amounts are equal, we would have sean = max
= $20 + $2x = $5x
Take like terms
20 = 5x - 2x
20 = 3x
divide through by 3
x = 20 / 3

What was the length of one side of the garage originally? What is the length of one side of the garage now? What was the percent increase in the length of one side?
Answers
The length of one side of the garage originally is 18.17 feet.
The length of one side of the garage now is 22.25 feet.
The percent increase is 22.4%.
What is the increase in the length of the garage?A square is a quadrilateral with four sides of equal length. A square has two diagonals of equal length that intersect at right angles.
Given the area of a square, the length of one side can be determined by calculating the square root of the area.
Area of the square = length²
Length of one side of the square = √area
√330 = 18.17 ft
Area of the garage after it was increased : (1 + percentage increase) x initial area
(1 + 0.5) x 330
1.5 x 330 = 495 feet²
Length of the side of the garage after it is increased = √495 = 22.25 feet
The percentage increase = (22.25 / 18.17) - 1 = 0.224 = 22.4%

b. The slope of the line perpendicular to y = 3/4x - 1 is: -4/3.
What is the Slope of Lines that are Perpendicular and Lines that are Parallel?If two lines are parallel to each other, they will have the same slope value. On the other hand, if the two lines are perpendicular to each other, they will have slopes that are negative reciprocals of each other.
Thus, given the equation, y = 3/4x - 1, the slope of this line is 3/4.
The negative reciprocal of 3/4 is -4/3.
Therefore, we can conclude that:

1. D. [tex]x = 7\sqrt{2}, y = 7[/tex]
2. B. [tex]x = 3\sqrt{2}, y = 2[/tex].
3. C. x = 6, y = 3.
4. C. [tex]x = 2\sqrt{5}, y = \frac{2\sqrt{15}}{3}[/tex]
What are the relations in a right triangle?There are three relations in a right triangle, given as follows:
The sine of an angle of the triangle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle of the triangle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle of the triangle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.For the first triangle, we have that:
tan(45º) = 7/y
1 = 7/y
y = 7.
Applying the Pythagorean Theorem:
x² = 7² + 7²
x = sqrt(2 x 49)
[tex]x = 7\sqrt{2}[/tex]
Hence the correct option is:
D. [tex]x = 7\sqrt{2}, y = 7[/tex]
For the second triangle, we have that:
tan(45º) = y/3
1 = y/3
y = 3.
Applying the Pythagorean Theorem:
x² = 3² + 3²
x = sqrt(2 x 9)
[tex]x = 3\sqrt{2}[/tex]
Hence the correct option is:
B. [tex]x = 3\sqrt{2}, y = 2[/tex].
For the third triangle, we have that:
[tex]\tan{30^\circ} = \frac{y}{3\sqrt{3}}[/tex]
[tex]\frac{\sqrt{3}}{3} = \frac{y}{3\sqrt{3}}[/tex]
y = 3 x 3/3
y = 3.
Then:
[tex]\sin{30^\circ} = \frac{y}{x}[/tex]
0.5 = 3/x
x = 6.
Hence the correct option is:
C. x = 6, y = 3.
For the fourth triangle, we have that:
[tex]\sin{30^\circ} = \frac{y}{\frac{4\sqrt{15}}{3}}[/tex]
[tex]0.5 = \frac{y}{\frac{4\sqrt{15}}{3}}[/tex]
[tex]y = \frac{2\sqrt{15}}{3}[/tex]
[tex]\cos{30^\circ} = \frac{x}{\frac{4\sqrt{15}}{3}}[/tex]
[tex]\frac{\sqrt{3}}{{2}} = \frac{x}{\frac{4\sqrt{15}}{3}}[/tex]
[tex]x = 2\sqrt{5}[/tex]
Hence the correct option is:
C. [tex]x = 2\sqrt{5}, y = \frac{2\sqrt{15}}{3}[/tex]
