Answer:

2/10 or in its simplest form 1/5

Step-by-step explanation:

there is 2 grey marbles so 2/10 (there is 10 marbles altogether)

so half of 2 is 1 and half of 10 is 5

so the answer is 1/5

(Counting number of grey marbles/ (number of total marbles) = 2/10 simplest form= 1/5

An employee earns a 12% commission rate on the cameras he sells. If he earns $384 in commission, what were his total sales?

Vlad1618 [11]

I do questions like these a little different than most people so...

384/12= 32 (32 is 1% of his sales)
32*100= 3200

His total sales were $3200.

Which equation represents the line that passes through the points (2,7) and (1,5)

Dimas [21]

Answer:

First we get the slope of line with points (2,3) & (1,5):

m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29

m=%285-3%29%2F%281-2%29=2%2F%28-1%29

m=-2, slope

Knowing the slop, we can get the intercept in point (1,1):

y=mx%2Bb, SLOPE- INTERCEPT

1=-2%281%29%2Bb

b=1%2B2=3

so, the eqn of the line: highlight%28y=-2x%2B3%29

The line with points (2,3) & (1,5): same slope because parallel, we'll check

VIA POINT SLOPE FORM:

m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29

m=%285-3%29%2F%281-2%29=2%2F-1 ----> m=-2, same right?

For the intercept thru pints (2,3):

Via SLOPE INTERCEPT FORM, we pick points (2,3)

3=-2%282%29%2Bb

b=3%2B4=7 ----> y intercept. The same value if you pick points (1,5).

Eqn of line: y=-2x%2B7 (Green line) parallel to y=-2x%2B3 (Red line)

See the graph,

--- see red line, it passes at point (1,1). Also green line passes points (2,3) & (1,5)

Jerrod’s family drove 1,778 miles from Denver, Colorado, to New York City. They averaged 61.7 miles per hour on the trip. Which

a_sh-v [17]

Answer:

The best estimate for the number of hours the family drove is 28.8 Hours.

Step-by-step explanation:

The distance Jarrod's family drove is 1778 miles and their average speed was 61.7 miles/hour, and we need the best estimate for the number of hours the family drove. For this we use the distance formula

$D=vt$

and use solve for t:

$t=\frac{D}{v}$ $=\frac{1778\:miles}{61.7\:miles/hr} = \boxed{28.8\:hours.}$

Thus the best estimate for the hours driven is 28.8 hours.

<em>It is only an estimate because the speed given is the average speed.</em>
