If i but a round wall clock and if the radius is 10m what is the circumference of the clock? ?

Answers

Answer 1

Answer: Circumference= radius(squred) times Pi(3.14)....

C= 10(10) times 3.14

314 is the answer

Answer 2

Answer: Circumference of circle= 2*idonthaveapisymbol*r2pirOrPi x diameter = 3.14 * 202(3.14)(10)

a charter bus travels 210 miles in 3 1/2 hours. assume the distance traveled is directly proportional to the time traveled. write and solve a direct variation equation to find how far the bus travel in 6 hours.

Answers

The constant of variation is 60 miles.

Direct variation formula: y = kx

y = 210
x = 3 1/2 miles
k = ?

k = y/x
k = 210 / 3 1/2 miles

*convert mixed fraction into a simple fraction
3 1/2 = (3*2+1)/2 = 7/2
k = 210 ÷ 7/2

Remember the rule of dividing fractions: multiply the 1st fraction by the reciprocal of the 2nd fraction.
1st fraction = 210 ⇒ 210/1
2nd fraction = 7/2 ⇒ reciprocal = 2/7

k = 210/1 * 2/7 = (210*2)/(1*7) = 420/7 = 60

The constant of variation is 60 miles.

To check:
y = kx
y = 60 (3.5)
y = 210 miles

We set up an equation: 210 miles/ (3 1/2 hours)= ? miles/ 6 hours

Cross multiply:
? miles* 3 1/2 hours= 210 miles* 6 hours
⇒ ? miles= 210 miles* 6 hours/ (3 1/2 hours)= 360 miles.

The bus would travel 360 miles in 6 hours~

Answers

15-3q+6=9

21-3q=9

-21 -21

-3q=-12

Divide bye 13 each side

Q=4

15 - 3q + 6 = 9 (re-arrange)
15 + 6 - 3q = 9 (add)
21 - 3q = 9 (subtract -21 from both sides)
-3q = 9 - 21 (add)
-3q = -12 (divide both sides by -3)
q = +4

The slope of a line is 0 and the y-intercept is 6 what is the equation of the line written in slope-intercept form

Answers

Answer:

The slope-intercept form of the the line is y=6.

Step-by-step explanation:

The slope intercept form of a line is

$y=mx+b$

where, m is slope and b is y-intercept.

It is given that the slope of a line is 0 and the y-intercept is 6.

Substitute m=0 and b=6 in the above equation.

$y=(0)x+6$

$y=0+6$

$y=6$

Therefore the slope-intercept form of the the line is y=6.

y = 6. Since there is no slope, if you plug 0 into y = mx + b where m = slope, then you get y = (0)x +b, which leads to y = b. Since b = y-intercept, b = 6. Therefore your equation is y = 6
