Answer:
13.5 euros
Step-by-step explanation:
A partir de la pregunta anterior, las dimensiones del terreno se dieron como 0.3 & 0.9 m
El terreno es de forma rectangular.
Paso 1
Encontramos el área de la tierra
Área = Largo × Ancho
Área = 0.3 m × 0.9 m
Superficie = 0.27m²
Paso 2
Nos dijeron
1 m² = 50 euros
0.27m² = x
Multiplicar cruzada
x = 0.27 × 50 euros
x = 13.5 euros
Alejandro ha pagado 13.5 euros por el terreno

A group of friends wants to go to the amusement park. They have $387.75 to spend on parking and admission. Parking is $5.50, and tickets cost $34.75 per person, including tax. How many people can go to the amusement park?
Answer:
Step 1:
Subtract $19 from total
366.50 - 19 = 347.5
Step 2:
Divide this total by the ticket price
347.50 / 34.75 = 10
Step 3:
You have your answer
10 people can go to the amusement park
Answer:
as many as 11 people
Step-by-step explanation:
n = # of people
5.50 + 34.75n ≤ 387.75
subtract 5.5 from each side to get:
34.75n ≤ 382.25
divide each side by 34.75
n ≤ 11

Solve the system of equations below.
5x + 2y = 9
2x - 3y = 15
Answer:
(3, -3)
Step-by-step explanation:
To solve for a system of equations, use substitution.
First, solve for one variable in an equation.
2x - 3y = 15
Add 3y to both sides.
2x = 3y + 15
Divide both sides by 2 to get x by itself.
x = 1.5y + 7.5
Put this in the other equation.
5x + 2y = 9
Substitute the variable.
5(1.5y + 7.5) + 2y = 9
Distribute the 5 inside the 1.5y + 7.5.
7.5y + 37.5 + 2y = 9
Combine like terms.
9.5y + 37.5 = 9
Subtract 37.5 from both sides.
9.5y = -28.5
Divide both sides by 9.5.
y = -3.
Now take this value and put it in the other equation to get your x.
2x - 3y = 15
Substitute variable.
2x - 3(-3) = 15
Multiply.
2x + 9 = 15
Subtract 9 from both sides.
2x = 6
Divide both sides by 2.
x = 3.

what percent of 4$ is 60 cents
no links
Answer:
15%
Step-by-step explanation:
You kind of have two ways to do this:
Way 1:
Find how many 60 cents fit into $4. To do that, divide $4 by $0.60 or 400 by 60. You get 6.66666667.
You can divide 100 by 6.66666667, and get 15%,
Way 2:
Knowing that 400 cents is 100%, you can divide 60 by the same number that you divide 400 by to get to 100. To get from 400 to 100, you divide by 4, so divide 60 by 4 and get the same answer, 15%
Hope that helps :)

Two friends Ana and Juan are buying books by joining the History Book
Club.
Ana has to pay a yearly fee of $15 to join. She spends a total of $525 for 30
books. How much was the price per book on average?
Juan has to pay a yearly fee of $10 to join. He spends a total of $350 for 23
books. How much was the price per book on average?
Write a function for Ana and Juan each to model the scenario to figure out
the total cost per book. Who has the better deal? Ana or Juan? Why?
Answer:
Ana spent $17 per book on average.
Juan spent $14.78 per book on average.
y = $15 + 17x--------- equation 1
y= $10 + 14.78 x------------- equation 2
Step-by-step explanation:
Ana has to pay a yearly fee of $15 to join.
She spends a total of $525 for 30 books.
The amount spent on books = Total amount - yearly fee
= $525- $15= $510
Price per book on the average = $510/30= $ 17
Ana spent $17 per book on average.
Juan has to pay a yearly fee of $10 to join.
He spends a total of $350 for 23 books.
The amount spent on books = Total amount - yearly fee
= $350- $10= $340
Price per book on the average = $340/23= $ 14.78≅ $15
Juan spent $14.78 per book on average.
The function can be established if y gives the total cost and x gives the number of books
y = $15 + 17x--------- equation 1
y= $10 + 14.78 x------------- equation 2
Juan has a better deal because the yearly fee is less also the price per book is less.

Walter needs new grass in the circular pen for his chickens. The pen has 308 feet of fencing. What is the area of the pen?
Answer: 7546feet²
Step-by-step explanation:
Since the pen has 308 feet of fencing, this is the perimeter of the circular pen and we can get the raduus which goes thus:
Circumference of a circle = 2πr
2πr = 308
2 × 22/7 × r = 308
44/7 × r = 308
r = 308 × 7/44
r = 49
Therefore, area of the circular pen will be:
= πr²
= 22/7 × 49 × 49
= 7546feet²

Mr. Weiss is ordering parts for his wheelchair on the Internet. The website is offering 15% off orders over $250.
Mr. Weiss selects a battery charger originally priced at $179, but marked down 35%. He also selects a mount for
his tablet computer for $99. In order to receive the 15% off, Mr. Weiss adds a cell phone holder for $56. What is
the total cost of Mr. Weiss's order after the discounts?
Answer:
$230.65
Step-by-step explanation:
$179 marked down by 35 % = $116.35
computer mount= $99
cell holder= $56
total= $271.35
marked down by 15% = $230.65 (230.6475)

What is the sum of the infinite series formula?The general formula for finding the sum of an infinite geometric series is S=a/r-1, where s is the sum, a1 is the first term of the series, and r is the common ratio.
Given that, sum = 4 + 16 + 64 + 256 + 1024
Using sigma notation, this can be expressed as:
[tex]^5\sum_{n=1}=4(4)^{n-1}[/tex]
Therefore, option A is the correct answer.

Expand and combine like terms.
(5 - 2x^4) (5 + 2x^4) =
Answer:
25 - 4x^8
Step-by-step explanation:
Use FOIL here.
Combine the first terms of both expressions.
5 * 5 = 25
Combine the outer terms of both expressions.
2x^4 * 5 = 10x^4
Combine the inner terms of both expressions.
-2x^4 * 5 = -10x^4
Combine the last terms of both expressions.
-2x^4 * 2x^4 = -4x^8
(a^x * a^y = a^(x+y).)
Now add those terms.
25 + 10x^4 - 10x^4 - 4x^8
Combine like terms to get:
25 - 4x^8.

A store is having a sale on jelly beans and almonds for 3 pounds of jellybeans in 2 pounds of almonds the total cost is $10 for 5 pounds of jellybeans in 6 pounds of almonds the total cost is $24 find the cost of each pound of jellybeans and each pound of almonds
Answer:
each lb of jellybeans = $1.50
each lb of almonds = $2.75
Step-by-step explanation:
let j = jellybean cost for each pound
let a = almond cost for each pound
3j + 2a = 10
5j + 6a = 24
Using elimination method:
15j + 10a =50
15j + 18a = 72
------------------------
-8a = -22
a = 2.75
using 3j + 2a = 10
3j + 2(2.75) = 10
3j + 5.5 = 10
3j = 4.5
j = 1.5
Find the surface area of a sphere with a diameter of 12 mm.
Answer:
A≈4.52×10-4m²
Step-by-step explanation:
Unit Conversion:
d=0.012m

A=4πr2
d=2r
Solving for A
A=πd2=π·0.0122≈4.52389×10-4m²
Answer:
1809.5574 mm²
Step-by-step explanation:
Input Data :
Length = 12 mm
Objective :
Find what is the surface area of the sphere for given input data?
Formula :
Surface Area = 4πr2
Solution :
Surface Area = 4 x 3.1416 x 122
= 4 x 3.1416 x 144
Surface Area = 1809.5574 mm²
What is the perimeter of a rectangle whose vertices are (2,7) (8,7) (211) (8,11)?
A) 24
b) 12
c)32
d) 40
e) 20
Answer:
e) 20
Step-by-step explanation:
Segment lengths:
|(2, 7) -> (8, 7)| = |(8-2, 7-7)| = |(6, 0)| = 6
|(8, 7) -? (8, 11)| = |(8-8, 11-7)| = |(0, 4)| = 4
because we know it's a rectangle, we can infer that the other two sides also have lengths 4 and 6, so the perimeter is 4+4+6+6=20

Answer:
Hello! answer: 105
Step-by-step explanation:
When doing these for squares you have to do base × height and for triangles you do base × height ÷ 2 So Lets do the triangles sense there more complex so we can get them out of the way. The base for the triangles our 5 and the height is 8 so we will do 5 × 8 = 40 now we will just divide that by 2 so 40 ÷ 2 = 20 now sense we have four identical triangles we will just multiply 20 by 4 so 20 × 4 = 80 now for the 1 in the middle its nice and simple just 5 × 5 so 5 × 5 = 25 now we just add 80 + 25 and 80 + 25 = 105 So 105 is the area!
