[tex]\huge\boxed{\text{6 by 10 inches}}[/tex]
Step-by-step explanation:
In order to solve for this, we can make two equations, where a is the length of the first side and b is the length of the second side.
[tex]ab=60[/tex] (Area)[tex]2a+2b=32[/tex] (Perimeter)We can now solve this systems of equations by using substitution.
Let's change the equation [tex]ab=60[/tex] into the form [tex]a= mb+c[/tex].
We can divide both sides by b.
[tex]a = \frac{60}{b}[/tex]
We can now plug [tex]\frac{60}{b}[/tex] in as a into [tex]2a+2b=32[/tex].
[tex]2(\frac{60}{b}) + 2b = 32[/tex]
Let's simplify this equation:
[tex]\frac{120}{b} + 2b = 32[/tex] [tex]2b^2 + 120 = 32b[/tex] [tex]2b^2 - 32b + 120 = 0[/tex] [tex]b^2 - 16b + 60 = 0[/tex] [tex]-10 \cdot -6 = 60\\-10 + -6 = -16[/tex] (Quadratic factoring, [tex]x_1 \cdot x_2=c, x_1 + x_2 = b[/tex]) [tex](b-10)(b+6)[/tex] [tex]b = 10\ \text{or}\ 6[/tex]Now, since we have both roots of this quadratic, we know that the two sides will be 10 and 6 inches long.
Hope this helped!

Al and Betty want to create a playlist of songs for their drive back and forth to school. Since Al and Betty have different tastes in music, they decide to compromise by only playing Al’s favorite rap and Betty’s favorite pop music that they can both agree upon.
Betty wants to include at least as many pop songs as rap songs. Al, in return, wants to include at least five rap songs. To provide enough variety to make the playlist interesting, they decide to include at least 20 songs altogether.
To create the playlist, Al and Betty will need to purchase the songs. They will have to pay $1.50 for each rap song and $1.00 for each pop song. How many of each type should they put on their playlist to minimize their cost?
Answers
Since’s Al’s only requirement was to have at least 5 rap songs, and rap songs are more expensive, only adding 5 is the cheapest way to go.

The area of the triangle below is 4.14 square inches. What is the length of the buse?
Answers
Answer:
3.6
Given:
are of triangle=4.14
height=2.3
Step-by-step explanation:
area of the triangle=1/2 × base × height
4.14 = 1/2 × base × 2.3
4.14 = 2.3/2 × base
by cross multiplying,
4.14 × 2 = 2.3 × base
8.28 = 2.3 × base
8.28/2.3 =base
To remove the decimal point, multiply with 100 in both numerator and denominator
8.28×100 / 2.3×100 = base
828/230 = base
base = 3.6
hope it helps you!
Answer:
3.6 inches.
Step-by-step explanation:
Area = 1/2 * base * height
4.14 = 1/2 * base * 2.3
1/2 * base = 4.14 / 2.3
base = 4.14 * 2 / 2.3
= 3.6.

A.Divide both sides by
B.Subtract from both sides.
C.Multiply both sides by
D.Add to both sides.
Answers
Answer:
C. Multiply both sides by 4.
Step-by-step explanation:
You are isolating the variable, g, and so you will do the opposite of all operations that occurs with the variable, g.
Note the equal sign, what you do to one side, you would do to the other. Isolate the variable, g, by multiplying 4 to both sides of the equation:
[tex]\frac{g}{4} * 4 = 24 * 4[/tex]
[tex]g = 24 * 4[/tex]
[tex]g = 96[/tex]

Choice D matches the description of a trapezoid, not a parallelogram. That description will not guarantee the figure is a parallelogram.
Owen measured a line to be 17.9 inches long. If the actual length of the line is 17.8 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?
Answers
Answer:
0.6%
Step-by-step explanation:
Percent Error = the absolute value of (actual value observed-expected value)/(expected value) x100%
(17.8-17.9)/(17.9) = -0.006
Absolute value is 0.006
0.006 times 100% equals 0.6%
The percent error of the measurement in the length is 10%.
What is percent error in measurement?Percent error is the difference between estimated value and the actual value in comparison to the actual value and is expressed as a percentage.Given is that Owen measured a line to be 17.9 inches long. The actual length of the line is 17.8 inches.
We can calculate the percentage error as -
%e = {(A.V. - E.V.)/(A.V.)} x 100
%e = (17.9 - 17.8) x 100
%e = 0.1 x 100
%e = 10%
Therefore, the percent error of the measurement in the length is 10%.

César ha cortado el segmento de cuerda de mayor longitud para amarrar una maleta.
Cómo determinar el segmento más largo utilizado de cuerdas
Una fracción es un número real formado por dos números enteros, un numerador y un denominador, respectivamente.
En esta pregunta debemos determinar quien tiene la mayor longitud de cuerda y para ello debemos aplicar propiedades tal que ambas fracciones tengan el mismo denominador. En consecuencia, la persona que tendría la mayor fracción tendría además el mayor numerador. A continuación, procedemos a realizar las siguientes operaciones:
40/100, 9/25
Al dividir cada término de la primera fracción por 4, tenemos lo siguiente:
10/25, 9/25
Por tanto, César ha cortado el segmento de cuerda de mayor longitud para amarrar una maleta. [tex]\blacksquare[/tex]

5b) 4
Step-by-step explanation:
You'll use Pythagorean theorem throughout this problem a lot. So, to find X, You have a right triangle with one leg of 6, and one leg of 2. 2 squared plus 6 squared equals c squared. 4 + 36 = c squared then you get 40 = c squared.
To get c by itself you'd square root both sides. So that leaves you with X = the square root of 40.
Now, to get Y, you have another triangle with a leg of 4, and another leg of the square root of 40. 4 squared = 16, and the square root of 40 squared is just 40. So, 16 + 40 = c squared. 56 = c squared, then again, to get the c value by itself you need to square root both sides, leaving you with Y = the square root of 56.

Exponential equationsGiven the expression that represents the interest earned on a money given as (1.0045)^4t
In order to calculate the approximate yearly percent, we will substitute t = 1 into the expression as shown:
f(t) = (1.0045)^4t
f(1) = (1.0045)^4(1)
