What is Area of Rectangle?The area of Rectangle is length times of width.
Given,
Gayla draws a rectangle.
Second rectangle:
Jared then draws a different rectangle by increasing both the length and the width by 5%.
Third rectangle:
Lyda draws a third rectangle by increasing both the length and the width of Gayla’s by 5 inches.
Let us assume 1 inches as 1 percentage.
So second rectangle and third rectangle are resulting rectangles scale drawings of one another
Hence, second rectangle and third rectangle are resulting rectangles scale drawings of one another

PLEASE HELP
-33.33333333333333 %A change from 27 to 18 represents a negative change (decrease) of -33.33333333333333%
Use the formula found below on this webpage to find the percent changeby replacing the given values:Percent change = New - Old|Old| 100%Percent change = 18 - 27|27| x 100 = -927 x 100 = -33.33333333333333decrease)
Where: 27 is the old value and 18 is the new value. In this case we have a negative change (decrease) of -33.33333333333333 percent because the new value is smaller than the old value.
The Answer is: -33.33333333333333% or 33.3Nicole has x dimes and y nickels. She has at least 15 coins worth a maximum of $1
combined. Solve this system of inequalities graphically and determine one possible
solution.
Answer:
Step-by-step explanation:
[tex]X + Y \geq 15\\\\10X + 5Y \leq 100[/tex]
we want to put it into terms of Y
[tex]y \geq 15 - x\\and\\5y \leq 100 - 10x\\y \leq 20 - 2x[/tex]
the graph is in the attached image. Any point in the shaded overlap region where x is greater than or equal to 0 (assuming you cannot have negative coins) works, e.g. (2, 14)
The solution of the inequalities is required.
One of the solutions is [tex](5,10)[/tex]
Number of dimes is [tex]x[/tex]
Number of nickels is [tex]y[/tex]
Minimum number of coins is 15.
So, [tex]x+y\geq 15[/tex]
Maximum total value of the coins is $1
So, [tex]0.1x+0.05\leq 1[/tex]
The equations are
[tex]x+y=15[/tex]
[tex]0.1x+0.05y=1[/tex]
Points of the first equation
[tex](0,15)[/tex] and [tex](15,0)[/tex]
Graph the points and draw a line through them.
Points of the second equation
[tex]x=0[/tex]
[tex]y=\dfrac{1}{0.05}=20[/tex]
[tex]y=0[/tex]
[tex]x=\dfrac{1}{0.1}=10[/tex]
[tex](0,20)[/tex] and [tex](10,0)[/tex]
Graph the points and draw a line through them.
The shaded regions can be determined by substituting the point in the equations.
One of the solutions is [tex](5,10)[/tex]
This means there are 5 dimes and 10 nickels.
[tex]5+10=15\geq 15[/tex]
[tex]0.1\times 5+0.05\times 10=1\leq 1[/tex]
Hence, one of the solutions is [tex](5,10)[/tex].

Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
-5 + 22 = r - 4 + 3r + 5
Step 2: Solve for r
Combine like terms: 17 = 4r + 1Subtract 1 on both sides: 16 = 4rDivide 4 on both sides: 4 = rRewrite: r = 4Step 3: Check
Plug in r to verify it's a solution.
Substitute: -5 + 22 = 4 - 4 + 3(4) + 5Add/Subtract: 17 = 3(4) + 5Multiply: 17 = 12 + 5Add: 17 = 17triangle ABC ~ triangle XYZ , where AB = 18 cm, BC = 30 cm , and CA = 42 cm . The longest side of triangle XYZ is 25.2 cm. What is the perimeter of triangle XYZ ?
Answer:
The perimeter of triangle XYZ is 54 cm
Step-by-step explanation:
In similar triangles, their corresponding sides are proportional, which means the ratios of the corresponding sides are equalTheir perimeters have the same ratio as their corresponding sides, which means P1 = r × P2, where r is the ratio of similarityTheir areas have the square of the ratio as their corresponding sides, which means A1 = r² × A2∵ Δ ABC is similar to Δ XYZ
∵ The longest side in Δ XYZ is 25.2 cm
→ That means its corresponding side in Δ ABC is the longest side
∵ AB = 18 cm, BC = 30 cm, CA = 42 cm
∴ The longest side in Δ ABC is CA
∴ CA is the corresponding side of the side of length 25.2 cm
∴ The ratio of similarity = [tex]\frac{25.2}{42}[/tex] = 0.6 ⇒ (r)
∵ The perimeter of Δ ABC = AB + BC + CA
∴ The perimeter of Δ ABC = 18 + 30 + 42
∴ The perimeter of Δ ABC = 90 cm
→ Use the 2nd fact above
∵ P of Δ XYZ = r × P of Δ ABC
∵ r = 0.6 and P of Δ ABC = 90
∴ The perimeter of Δ XYZ = 0.6 × 90
∴ The perimeter of Δ XYZ = 54 cm

Solve 3/5k-5=7/10k by eliminating the fraction. Explain how you determine what to multiply each term by and all the steps to solving the equation.
9514 1404 393
Answer:
k = -50
Step-by-step explanation:
The fraction denominators are 5 and 10. The least common multiple of those values is 10. This means we can eliminate fractions by multiplying both sides of the equation by 10:
6k -50 = 7k
Subtracting 6k from both sides of the equation leaves you with the solution:

En la casa de la familia de Trevor viven 6 personas (incluyendo a Trevor) y hay 3 baños. En el último mes, cada
persona se bañó durante un promedio de 480 minutos y utilizó un promedio de 72 litros de agua al bañarse
(en todo el mes). El agua cuesta 0.20 dólares por litro.
¿Cuánto dinero gastó la familia de Trevor en total en agua al bañarse el mes pasado?
dólares.
Answer:
La familia de Trevor gastó 86.4 dólares al bañarse en todo el mes.
Step-by-step explanation:
El costo del agua viene dado por:
[tex] C = \$0.20/L [/tex] (1)
Y cada persona de la familia de Trevor gasto en promedio 72 litros de agua. Si la familia tiene 6 integrantes (incluido Trevor) entonces:
[tex] A = 72 L*6 = 432 L [/tex] (2)
Entonces, toda la familia usó 432 litros de agua en promedio en todo el mes.
Para saber el dinero total gastado por la familia debemos multiplicar la ecuación (1) y la ecuacion (2):
[tex] C = \$0.20/L*432 L = \$86.4 [/tex]
Por lo tanto, la familia de Trevor gastó 86.4 dólares al bañarse en todo el mes.
Espero que te sea de utilidad!
Usando proporciones, hay que la familia de Trevor gastó 86.4 dólares en total en agua al bañarse el mes pasado.
En la casa, hay 6 personas.Cada persona utilizó un promedio de 72 litros de agua.Por eso, en todo, 6 x 72 = 432 litros de agua fueron usados.
Cada litro cuesta $0.2. De esa forma, el total de dinero gasto es de:
T = 0.2 x 432 = 86.4.La familia de Trevor gastó 86.4 dólares en total en agua al bañarse el mes pasado.

A person has $28,000 invested in stock A and stock B. Stock A currently sells for $50 a share and stock B sells for $60 a share. If stock B triples in value and stock A goes up 50%, his stock will be worth $69,000. How many shares of each stock does he own?
Answer:
Number of stock A = 200
Number of stock B = 300
Step-by-step explanation:
Let :
Number of stock A shares = a
Number of stock B shares = b
Worth of stock A = 50 * a = 50a
Worth of stock B = 60 * b = 60b
50a + 60b = 28000 - - - (1)
Triple the value of stock B:
3 * 60 = 180
Value of stock A goes up by 50%
(100 + 50)% * 50 = 1.5 * 50 = 75
75a + 180b = 69000 - - - (2)
50a + 60b = 28000
75a + 180b = 69000
Multiply equation 1 by 3 and subtract
150a + 180b = 84000
75a + 180b = 69000
75a = 15000
a = 15000/75
a = 200
75(200) + 180b = 69000
15000 + 180b = 69000
180b = 69000 - 15000
180b = 54000
b = 300

Write the linear equation in Slope-Intercept Form y = mx + b of the line that passes through the given points, then graph
the line.
Answer:
y = 3x + 7.
To graph the line mark off the 2 points and draw a line through them.
Step-by-step explanation:
The slope = (-2-7) / (-3-0)
= -9/-3
= 3.
The value of b is found using the point-slope form of a line:
y - y1 = m(x - x1)
using m = 3, (x1, y1) = (0, 7):
y - 7 = 3(x - 0)
y = 3x + 7.
Two rectangular boxes have the same volume. One box is a cube, and the other box has dimensions 8 ft by 4 ft by 16 ft. How many feet long is an edge of the cube?
Answer:
8 feet
Step-by-step explanation:
All you have to do is find the area of one box and find the root to find the cube edge, as it says they have the same volume.
Lets find the volume of the rectangular box.
8 x 4 x 16 =
32 x 16 =
512.
The volume of the cube is 512 feet cubed, but you are looking for the edge.
The edge cubed should be equal to 512 feet cubed.
So 512 cube root is 8, because 8 x 8 x 8 is 512.
8 feet.
