You've gone to fruit stand to get some fresh produce. You
notice that the person in front of you gets 5 apples and 4 oranges
for 10 dollars. You get 5 apples and 5 oranges for 11 dollars.
Create a system of equations that represents this situation.
Step-by-step explanation:
Let $x be the price of an apple and $y be the price of an orange.
5x + 4y = 10
5x + 5y = 11
btw the solution is
y = 1
x = 6/5
What fraction of 400 gallons is 180 L? Give your answer in simplest form. 1 gallon = 4.5 L.
Answer:
400 gallons are 1100 / 63 of 126 L.
Step-by-step explanation:
Given
1 Gallon = 4.5 L
To determine
What fraction of 400 gallons is 180 L
as
1 Gallon = 4.5 L
so
400 Gallons = 400 × 4.5
= 1800 L
In order to determine the fraction of 400 gallons is 180 L, just divide 1800 by 180, so
Fraction = 2200 ÷ 126
= 1100 ÷ 63
Therefore, 400 gallons are 1100 / 63 of 126 L.

The missing options are:
a) $23.24b) $19.64c) $29.14d) $26.74We have:
John spends $2.75 on donuts for his office employees every weekday. On Sunday mornings he takes his wife and kids to the donut shop and spends $12.99.
Let the total number of working days in a week be 5
Total money spend on employees = 5×2.75 = $13.75
Total money spend on donuts throughout the week = 13.75 + 12.99
= $26.74
Thus, the total money spends on donuts throughout the week is $26.74 option (d) is correct.

Step-by-step explanation:
Rate of Change
The average velocity is defined as the rate of change of the distance with respect to time. The table shows the distances of an object as a function of time.
It's required to find the average velocity between 8 s and 20 s.
The rate of change can be approximated as the slope between two points. We take from the table the points (8,32) and (20,10) and calculate the slope.
The slope can be calculated with the equation:
[tex]\displaystyle v=\frac{d_2-d_1}{t_2-t_1}[/tex]
[tex]\displaystyle v=\frac{10-32}{20-8}=\frac{-22}{12}[/tex]
Simplifying:
[tex]\displaystyle v=-\frac{11}{6}[/tex]
Choice: B. [tex]\mathbf{-\frac{11}{6}\ \frac{inches}{second}}[/tex]

Use trigonometry
The ratio of the adjacent side of a right triangle to the hypotenuse is called the cosine:
cos x = 18/25 = 0.72cos x = 0.72x = arccos 0.72x = 43.9455° ≈ 44.0° roundedA submarine was at the surface of the water. 21 seconds later, it was at a depth of 294 meters. What was the average change in the submarines depth each second?
Step-by-step explanation:
21 seconds = -294 meters
=> 1 second = -294/21 = -14 meters
Hence the average change is -14 meters per second.
The average change in the submarines depth is -14 meters per second.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
A submarine was at the surface of the water.
21 seconds later, it was at a depth of 294 meters.
We have to find the average change in the submarines depth each second.
According to given question we have
21 seconds = -294 meters
=> 1 second = -294/21 = -14 meters
Hence ,the average change in the submarines depth is -14 meters per second.

Answer:
x=35, y=35
Step-by-step explanation:
To be honest, you don't even have to do any maths to figure this one out if you know the theory.
Basically, any angles standing on the same arc (like x and y) are equal. So we know x=y, and the first option(x=35,y=35) is the only option where x is the same as y.
The area of a square can be represented by the expression x^10. Which monorail represents a side of a square
Answer:
The length of the side of a square is [tex]\mathbf{x^5}[/tex]
Step-by-step explanation:
Area of square = [tex]x^{10}[/tex]
We need to find length of the side
The formula used will be:
[tex]Area\:of\:square=(length)^2[/tex]
Putting value of area of square, we can find length
[tex]Area\:of\:square=(length)^2\\x^{10}=(length)^2\\Switching\:sides\\(length)^2=x^{10}\\Taking\:square\:root\:on\:both\:sides\\\sqrt{(length)^2}=\sqrt{x^{10}}\\(length)^{\frac{2}{3} }=x^{\frac{10}{2}} \\length=x^5[/tex]
So, length of the side of a square is [tex]\mathbf{x^5}[/tex]

The length of a rectangle is
2
meters less than
3
times the width. The perimeter is
44
meters. Find the width.
Answer:
They did not state exactly what the width or length is. So in this case, let's name the number of width to be x. And thus we can derive to the conclusion of,
Step-by-step explanation:
Width : x
Length : x-44 (from the 1st sentence of question)
So, We all know that a rectangle has 2 Lengths and 2 widths. So we can derive the conclusion that,
2(x)+2(x-44)=150150
2x+2x-88=150150
4x-88= 150150
4x= 150150+88=150238
4x=150238
x= 150238÷4
=37559.5
Answer:
The width is 8 meters and the length is 3(8)-2=22 meters. Hope this helps (owo)/ brainlist please.
Step-by-step explanation:
Let x= the width
then 3x-2= length (because the length is 2 meters less than 3 times the width)
P=2l+2w
60=2(lenght)+2(width)
60=2(3x-2)+2x
60=6x-4+2x Distribute
60=8x-4 Combine like terms
64=8x Divide both sides by 8
8=x

A factory produces 161 cars in 7 hours at this rate how many cars will the factory produce in 1 week Assume the factory runs 24 hours a day 7 days a week
Answer:
3864 cars.
Step-by-step explanation:
First, to simplify the equation, we figure out how many hours are in a week.
24 x 7 = 168.
You can also figure out how many cars are made in a single hour.
161 / 7 = 23.
Now, we use the two in one final equation to get our final answer.
23 x 168 = 3864.

if x=2y-5 and z=16y^3, what is z in terms of x
Answer:
z in terms of x is [tex]\mathbf{z=16\left(\frac{x+5}{2}\right)^3}[/tex]
Step-by-step explanation:
We are given:
[tex]x=2y-5\: and\: z=16y^3[/tex]
We need to find z in terms of x
First we can find value of y from x =2y-5
[tex]x =2y-5\\x+5 = 2y\\y=\frac{x+5}{2}[/tex]
Now, we can put value of y in [tex]z=16y^3[/tex] to find z in terms of x
[tex]z=16y^3\\Put\:y=\frac{x+5}{2}\\z=16(\frac {x+5}{2})^3[/tex]
So, z in terms of x is [tex]\mathbf{z=16\left(\frac{x+5}{2}\right)^3}[/tex]
The selling price of an item is $600. It is marked down by 10%, but this sale price is still marked up
from the cost of $450. Find the markup from cost to sale price.
The markup is $ (Round to the nearest dollar as needed.)
Step-by-step explanation:
Sale price
= Marked down by 10% from selling price
= 90% of selling price
= 0.9 * $600
= $540.
Sale price - Cost price
= $540 - $450 = $90.
The markup from cost to sale is $90.
The markup from cost to sale price will be $90.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
The selling cost of a thing is $600. It is discounted by 10%, however, this deal cost is as yet increased from the expense of $450.
The sale price is given as,
Sale price = 0.90 x $600
Sale price = $540
The markup cost to sale will be given as,
⇒ $540 - $450
⇒ $90
The markup from cost to sale price will be $90.
