Awalmart truck driver estimates that it will take him 12 hours to drive 1152 km. after 5 hours, he has driven 520 km. (a) according to his original estimate, how far would he drive in 1 hour? show your number sentence and solution. (b)is he on schedule to arrive on time? use a unit rate to explain your reasoning.

Yes, he will be there on time

Step-by-step explanation:

Based on his original estimate - divide miles by hours

    1152/12 = 96 km/hour

Based on his actual time milage - divide miles by hours

    520/5 = 104 KM/hour

Yes, he is driving faster than he estimated.

answer: the equation matches the regression

step-by-step explanation:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
