mylen [45]

Answer:

B. 120

Step-by-step explanation:

<u>so his average speed is 20 mph in heavy traffic, and 50 mph in light traffic</u>

in 1 hour of heavy traffic, he would have gone 20 miles because if his average speed is 20 mph (miles per hour) in heavy traffic, then in 1 hour he would have gone 20 miles

20(1) = 20

in 2 hours of light traffic, he would have gone 100 miles because if his average speed is 50 mph (miles per hour) in light traffic, then in 2 he would have gone 100 miles

50(2) = 100

in total, if you add the 20 and 100, you find out how far abdul traveled:

20 + 100 = 120

so in 1 hour of heavy traffic and 2 hours in light traffic, abdul would have traveled 120 miles

(1.6x10^12) divided by (8.01x10^23) =?
oksano4ka [1.4K]

Answer:

1.99750312 * 10 ^(-12)

Step-by-step explanation:

When we divide numbers in scientific notation

1.6*10^12

----------------

8.01 * 10^23

We divide the numbers out front and subtract the exponents on the powers of 10

(1.6/8.01) * 10^(12-23)

.199750312 * 10^(-11)

But this is not proper scientific notation.  We need 1 number in front of the decimal.  If we move the decimal 1 place to the left, we subtract 1 from the exponent

1.99750312 * 10 ^(-11-1)

1.99750312 * 10 ^(-12)

Write the equation of the line that passes through (3, 4) and (2, –1) in slope-intercept form.
Norma-Jean [14]
First you have to find slope (m)

m = (y2 - y1) / (x2 - x1)
m = (-1 - 4) / (2 - 3)
m = (-5) / (-1)
m = 5

now you have to use point-slope
y - 4 = 5 (x - 3)
y - 4 = 5x - 15
y = 5x - 11 is your answer
