8 The perimeter P of a regular pentagon is 90 cm. What is the length x of each
side?
Answer:
18cm
Step-by-step explanation:
You would do 90/5 which is 18. Each side of the pentagon is 18cm.
Answer:
X = 18
Step-by-step explanation:
This is a regular pentagon, meaning that each side is the same. Now, since we know the perimeter, we can divide that by 5 to find each side's length (x). 90/5 = 18, so the length x of each side is 18.
The perimeter Of a rectangle is 30 inches if it’s Lance is three times it’s width find the dimensions.
Answer:
Width: 3.75
Length: 11.25
Answer:
the width is 3.75 inches. The length will be 3*3.75=11.25 inches.
Step-by-step explanation:
30 inches=2(L+W) Divide each side by 2. 15 inches=L+W Substitute for L.

Answer:
32
Step-by-step explanation:
The number that has the same value as [tex](4^{-1})(2^3 \div 4^{-2})[/tex] is 32
The numeric expression is given as:
[tex](4^{-1})(2^3 \div 4^{-2})[/tex]
Evaluate the exponents
[tex](4^{-1})(2^3 \div 4^{-2}) = \frac 14 * 8 \div \frac 1{16}[/tex]
Express as products
[tex](4^{-1})(2^3 \div 4^{-2}) = \frac 14 * 8 * 16[/tex]
Evaluate the products
[tex](4^{-1})(2^3 \div 4^{-2}) =32[/tex]
Hence, the number that has the same value as [tex](4^{-1})(2^3 \div 4^{-2})[/tex] is 32

Norma and Albert both clean pools. Each charges a flat fee to clean a pool. Norma cleans 12 pools in 8 hours and earns $270. Albert cleans 9 pools in 7.5 hours and earns $195.75.
Answer:
Step-by-step explanation:
Noma cleans 12 pools in 8 hours
How many pools in how many minutes?
8 x 60= 480
He cleans 12 pools in 480 minutes
How many minutes does he take to clean a pool?
480/12 = 40
He cleans a pool in 40 minutes.
How much does he earn to clean a pool?
since he cleans 12 pools to earns $270
then 270/12 =22.5
Therefore, he charges $22.5 to clean a pool in 40 minutes.
Albert 9 pools in 7.5 hours
How many pools in how many minutes?
7.5 x 60= 450
He cleans 9 pools in 450 minutes
How many minutes does he take to clean a pool?
450/9 = 50
He cleans a pool in 50 minutes.
How much does he earn to clean a pool?
since he cleans 9 pools to earns $195.75
then 195.75/9 =21.75
Therefore, he charges $21.75 to clean a pool in 50 minutes.

Find the length of arc CD. Use 3.14 for pi. Round to the nearest tenth.
9.2
.......................
The length of arc is 9.1506 cm.
What is Length of Arc?The length of an arc refers to the distance along the curve of a circle between two points on that curve. It is a measure of the portion of the circumference of a circle or any other curved shape.
The Formula for Length of Arc is θ/360 x 2πr.
We have,
Radius = 7.9 cm
Angle = 66.4 degree
Now, length of Arc
= θ/360 x 2πr
= 66.4 / 360 x 2 x 3.14 x 7.9
= 0.18444 x 2 x3.14 x 7.9
= 9.1506 cm
Thus, the length of arc is 9.1506 cm.

APRENIZAJE ESPERADO: Resuelve problemas de potencias con exponente entero y aproxima raíces cuadradas.
Partes de una potenciación:
La base es la cantidad que se multiplica por sí misma tantas veces como lo indique el exponente, en este caso la base es el número 6.
El exponente indica la cantidad de veces que la base se tiene que multiplicar por sí misma, en este ejemplo el exponente es el 3, el cual indica que el número 2 se tiene que multiplicar 3 veces por sí mismo, es decir 2 x 2 x 2. (Ojo: multiplicar 2 x 3 es un procedimiento equivocado en este caso de la potenciación).
La potencia es el 8; es el resultado de multiplicar 2 x 2 x 2
ACTIVIDAD: Con base a lo anterior, completa la tabla siguiente.

You place a cup of 205°F coffee on a table in a room that is 72°F, and 10
minutes later, it is 195°F. Approximately how long will it be before the coffee
is 180°F? Use Newton's law of cooling:
Every 10 min it goes down 10 degrees.
We need it to go down 205-180=25 degrees.
Since it goes down 1 degree per min, it would take 25 min. I don't know about the law part though.
Answer:
27 minute is correct via A P E X
