Answer from: iixyloa

The car travels 754 inches in 6 revolutions of wheel.

Distance in one revolution

Since the car covers the circumference of the wheel in one revolution, we have that

C = 2πr where r = radius of wheel = 20 inches

So, C = 2π × 20 in

C = 40π in

So, the wheel covers 40π inches in one revolution.

Distance in 6 revolutions

We require the distance covered by the car in 6 revolutions.

So, distance = number of revolutions × distance per revolution

= 6 × 40π

= 240π

= 753.98 in

≅ 754 in

So, the car travels 754 inches in 6 revolutions of wheel.

Distance covered in round of wheel will be equal to the circumference of the wheel.

Radius of a car wheel = 20 inches
Diameter of car wheel = 2 radius = 2 × 20 inches = 40 inches

Circumference of wheel = π diameter

$circumference \: \: of \: \: wheel = \frac{22}{7} \times 40 \:inches$

$So, \: distance \: \: covered \: \: in \: \: one \: \: round \: \: is \: \: \frac{22}{7} \times 40 \: inches$

Similarly,

$So, \: \: distance \: \: covered \: \: in \: \: 6 \: rounds \: \: = 6 \times \frac{22}{7} \times 40$

So, distance covered in 6 rounds is 754.28 inches

Answer from: Quest

$x=\frac{3}{4}$

step-by-step explanation:

we are given

$-6+2x=6x-9$

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

$-6+2x-2x=6x-9-2x$

$-6=4x-9$

add both sides by 9

$-6+9=4x-9+9$

$3=4x$

divide both sides by 4

we get

$x=\frac{3}{4}$

Answer from: Quest

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
