Question 5 (ID=172336)
Beth spins the spinner below and gets purple. Spinning the spinner a second time is
OA:
a dependent event because the outcome of the second spin depends on the outcome of the first spin.
OB:
a dependent event because the outcome of the second spin does not depend on the outcome of the first spin.
O C:
an independent event because the outcome of the second spin depends on the outcome of the first spin.
D:
an independent event because the outcome of the second spin does not depend on the outcome of the first spin.
Mark Question For Review

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

-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

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
