The earth has a diameter of 7926.41 miles. What is the circumference of the earth?

2 answers:

8 0

Diameter= 2r= 7926.41

Now lets do the math

2r/2= 7926.41/2

r= 3963.205

Circumference= 2 x pi x r= 2 x 3.1415 x 3963.205= 24900.817 miles

Make sure you label!

Circumference of a circle is: 2(pi)r

Since it's the diameter that is given, then 2r is just the diameter.

Circumference of the Earth = (7926.41 miles)(3.14159265358979...)

= 24901.55 miles

Step-by-step explanation:

We reflect We triangle across both axis so the x and y values will both switch.

Our triangle is originally in the second quadrant but then go to the 4the after we reflect it.

Find slope intercept form of 5x+8y=120 passing through (4,5)

yarga [219]

Answer:

$y=-(5/8)x+(15/2)$ or $y=-0.625x+7.5$

Step-by-step explanation:

The question is

Find the slope intercept form of the line parallel to the line 5x+8y=120 passing through (4,5)

step 1

Find the slope of the given line

we have

$5x+8y=120$

isolate the variable y

$8y=-5x+120$

$y=-(5/8)x+15$

The slope of the given line is m=-5/8

step 2

Find the slope of the line parallel to the given line

we know that

If two lines are parallel, then their slopes are the same

The slope of the parallel line to given line is m=-5/8

step 3

Find the equation of the line into slope intercept form

The equation of the line into slope intercept form is equal to

$y=mx+b$

we have

m=-5/8 and point (4,5)

substitute and solve for b

$5=-(5/8)(4)+b$

$b=5+(20/8)$

$b=60/8=15/2=7.5$

substitute

$y=-(5/8)x+(15/2)$

$y=-0.625x+7.5$

What number is missing? explanation please

-BARSIC- [3]

The missing number is 12

because the pattern is that the the numbers below and to the right of a number equals that number. ex: 3+4=7. so in order to find the missing number you have to do the opposite of addition, which is subtraction. (17-5=12)
