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

Write the equation of a line that passes through the point (0, 3) and (-4, 11). *
Answers
Answer:
[tex] \large \boxed{y = - 2x + 3}[/tex]
Step-by-step explanation:
Goal
Write the equation of a line with given coordinate pointsGiven
Coordinate points which are (0,3) and (-4,11).Step 1
Use the slope formula also known as rise over run to calculate the slope.[tex] \large \boxed{m = \frac{y_2-y_1}{x_2-x_1} }[/tex]
Substitute coordinate points in.
[tex]m = \frac{11 - 3}{ - 4 - 0} \\ m = \frac{8}{ - 4} \longrightarrow \frac{2}{ - 1} \\ m = - 2[/tex]
Step 2
Substitute the value of slope in the slope-intercept form.[tex] \large \boxed{y = mx + b}[/tex]
where m = slope and b = y-intercept.
[tex]y = - 2x + b[/tex]
Step 3
Substitute any given coordinate points in the new equation to find the value of b.Substitute both coordinate points still give the same solution.
Step 3.1 — (0,3)
[tex]y = - 2x + b \\ 3 = - 2(0) + b \\ 3 = 0 + b \\ 3 = b[/tex]
Step 3.2 — (-4,11)
[tex]y = - 2x + b \\ 11 = - 2( - 4) + b \\ 11 - 8 = b \\ 3 = b[/tex]
Therefore, the value of b is 3.
Step 4
Substitute the value of b in the equation.[tex]y = - 2x + b \\ y = - 2x + 3[/tex]
Hence, the equation of a line is y = -2x+3.
(0,-9)after a rotation of 180 counterclockwise about the origin
Answers
Since a rotation from the origin by 180 converts (x,y) to (-x,-y)
The coordinate after a rotation of 180° counterclockwise about the origin is (0, 9).
What is rotation?Rotations are transformations that turn a shape around a fixed point. To rotate a shape we need: a centre of rotation. an angle of rotation (given in degrees) a direction of rotation – either clockwise or anti-clockwise.
The given coordinate is (0, -9).
Rotation rule:
Rotating a point that has the coordinates (x,y) 180° about the origin in a clockwise or counterclockwise direction, produces a point that has the coordinates (-x,-y).
Now, (0, -9) → (0, -(-9))
(0, -9) → (0, 9)
Therefore, the coordinate after a rotation of 180° counterclockwise about the origin is (0, 9).

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.
Answers
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.
equivalent Find the number that makes the ratio equivalent to 1:7. 4:
Answers
Answer:
28
Step-by-step explanation:
Ratios are like fractions. Since you're finding an equivalent ratio, u can set them up like equivalent fractions and put an x where the missing number would go:
[tex]\frac{1}{7} = \frac{4}{x}[/tex]
You can either cross multiply and then solve for x, but it's easier to just think about it. The fractions are equivalent, right? So for them to be the same you'd have to do to the bottom what u do to the top.
To get from 1 to 4, you multiply by 4. By that logic, to get from 7 to x you'd have to multiply by 4 as well. Therefore x = 7x4, which is 28.
So x = 28

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.

8 The perimeter P of a regular pentagon is 90 cm. What is the length x of each
side?
Answers
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.

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).
