<u>Answer:</u>
1130400 km
<u>Step-by-step explanation:</u>
We know the formula for circumference of a circle:
<em>Circumference = 
</em>
So we need the radius of Saturn ring to calculate its circumference.
We are given Saturn's diamter which is 120,000km; and know that Saturn's ring extends for about 120,000 km from the circumference of the Saturn.
Therefore, the radius of Saturn's ring will be 120000 km plus half of the diameter of Saturn:
Radius of Saturn's ring = 120000 + (120000/2) = 180000 km
Circumference of Saturn's rings = 2 x 3.14 x 180000 = 1130400 km
Answer:
Step-by-step explanation:
X =75
The slope intercept form of a line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0). We are given that the slope is 4/5 and the point (0,1) so we know m=4/5 and b=1 so:
y=4x/5+1 now to rearrange into standard form ax+by=c
y=(4x+5)/5
5y=4x+5
5y-4x=5
So the answer is D.
However, by convention, in standard form, the equation is usually expressed with a positive coefficient for x.
5y-4x=5 SHOULD be expresses so the x has a positive coefficient, divide both sides by -1 and you have the technically correct form:
4x-5y=-5
Apparently whomever/whatever posed this question to you was unaware of this convention :P
Answer:
x = 4
Step-by-step explanation:
4x-5 = 2x+3
subtract 2 x from each side and add 5 to each side
2x = 8
x = 4
Answer:
110 words in 5 min, 220 words in 10 min
Step-by-step explanation:
y = mx (there is no intercept because you can't type anything in 0 minutes)
66 = 3m
m = 22
y = 22x
5 minutes:
y = 22(5) = 110 words
10 minutes:
y = 22(10) = 220 words
