Identify the correct weight to the nearest 1/8 pound, then reduce the fraction if possible.

What is the equation of a line that is parallel to

mariarad [96]

Answer:

23+5y=23x +5

5y=23x-18

y=23/5x - 18/5

<u>y--7=</u>23/5

x-6

5y+35=23x-138

5y=23x-203

y=23/5x -203/5

The expression 4x/5 - 2x/5 is equivalent to...

madreJ [45]

If you would like to know the equality of the expression 4 * x/5 - 2 * x/5, you can calculate this using the following steps:

<span>4 * x/5 - 2 * x/5 = (4 - 2) * x/5 = 2 * x/5
</span>
The correct result is 2 * x/5, which is none of the results written above.

1. What is the area of a circle with a diameter of 12.6 in.?

Rudik [331]

Answer:

Part 1) $A=124.63\ in^{2}$

Part 2) Option b

Part 3) As n increases, ns get closer to $2\pi r$

Part 4) Option c $16\pi\ ft^{2}$

Part 5) Option b. $12.25\pi\ m^{2}$

Step-by-step explanation:

Part 1) What is the area of a circle with a diameter of 12.6 in.?

we know that

the area of a circle is equal to

$A=\pi r^{2}$

we have

$r=12.6/2=6.3\ in$ -----> the radius is half the diameter

substitute the values

$A=(3.14)(6.3^{2})=124.63\ in^{2}$

Part 2) Which explanation can be used to derive the formula for the circumference of a circle?

First find the relationship of the circumference to its diameter by finding that the length of the diameter wraps around the length of the circumference approximately π times.

Use this relationship to write an equation showing the ratio of circumference to diameter equaling π

so

$\frac{C}{D}=\pi$

Rearrange the equation to solve for the circumference

$C=\pi D$

Substitute the diameter for 2 times the radius

$D=2r$

$C=2\pi r$

Part 3) we know that

If n increases

then

the product ns get closer to the circumference of the circle

so

the circumference of a circle is equal to $C=2\pi r$

therefore

As n increases, ns get closer to $2\pi r$

Part 4) What is the area of a circle whose radius is 4 ft?

we know that

the area of a circle is equal to

$A=\pi r^{2}$

we have

$r=4\ ft$

substitute the values

$A=(\pi)(4^{2})=16\pi\ ft^{2}$

Part 5) The circumference of a circle is 7π m.

What is the area of the circle?

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

$C=7\pi\ m$

substitute and solve for r

$7\pi=2\pi r$

$r=3.5\ m$

Find the area of the circle

the area of a circle is equal to

$A=\pi r^{2}$

substitute

the area of a circle is equal to

$A=\pi (3.5^{2})=12.25\pi\ m^{2}$

Here are six number cards -7, -5, -3,3,1,-1 arrange these cards into three pairs with the same total

pantera1 [17]

Answer:

The sum of all of the cards is -7 + (-5) + (-3) + 3 + 1 + (-1) = -12 which means that each pair must have a sum of -12 / 3 = -4. This means that the pairs are -7 and 3, -5 and 1, and -3 and -1.
