GIVEN:
We are given two points on a line and these are;
Required;
We are required to determine the slope of the line passing through these points.
Step-by-step solution;
The slope of a line is given by the formula;
The variables are;
We can now substitute these into the formula and then simplify;
ANSWER:
The slope of the line passing through the given points is;
First convert the distance to miles
<span>9.5 × 10^12 km x 0.62 miles/km </span>
<span>= (0.62 × 9.5) x 10^12 miles </span>
<span>= 5.9 × 10^12 miles </span>
<span>But we want to triple that, because it is 3 light years (not just 1): </span>
<span>3 x 5.9 × 10^12 miles </span>
<span>≈ 18 × 10^12 miles </span>
<span>≈ 1.8 × 10^13 miles </span>
<span>Next divide by the speed to get the time (in hours). </span>
<span>t = 1.8 × 10^13 miles / 17000 miles/hour </span>
<span>Let's convert the speed to scientific notation: </span>
<span>t = 1.8 × 10^13 / 1.7 x 10^4 </span>
<span>t = (1.8 / 1.7) × (10^13 / 10^4) <-- when dividing powers with the same base, subtract the exponents </span>
<span>t ≈ 1.1 × 10^9 </span>
<span>Let's convert that back to standard notation. </span>
<span>Answer: </span>
<span>1,100,000,000 hours</span>
Answer:
42 unit²
Step-by-step explanation:
the hexagon is made up of 2 triangles, both have base 7 and height 2, and one middle rectangle with width 7 and length 4
area = (2 x 7) / 2 x 2 + 4 x 7 = 14 + 28 = 42
Answer:
53/100?
Step-by-step explanation:
I mean you can't really simplify it any more. There's no LCD, GCD. Can't divide it evenly.
To solve it I just looked at the number of places, (3 which mean 100.)
Then I looked at the numbers, (53.)
So you just turn that into a fraction...
Answer:
C. 4:13
Step-by-step explanation:
there are 4 students in the 4th grade and 4+9= 13 so it is 4:13
