Step-by-step explanation:
They started shopping at 11:45 am.
It took 1 hour to shop and 30 minutes to eat, again it took 1 hour 30 min to play games, if you add up, total 3 hours .
Use proportions to find the height of the building-
=
The x is the height of the building.
It is over 1 (the height of the other building) because both are heights.
Similar triangles are in proportion so the other fraction is in proportion to it.
Cross multiply(x times .2) (8 times 1). You will get this equation-
.2x=8
Solve for x by dividing-
x=40
Since this was done in meters, the answer is-
The building is 40 meters.
Answer:
Step-by-step explanation:
Since this is a 4th degree polynomial, 2 of the roots will not be real. Finding them is next to impossible off a calculator until the real ones are found first. That's simple enough process.
and
Divide both sides by 5:
Rewrite to get
which simplifies down to
Taking the square root of both sides gives you the real roots of x = 2 and -2.
That leaves you with 2 roots that are imaginary. After you factor out the 2 and the -2 by synthetic division, you are left with the depressed quadratic
Factor out the 5:
So the final answer is D.
Answer:
13.50
Step-by-step explanation:
First find the discount
18 * 25%
18 * .25
4.5
Subtract this from the price
18 - 4.5
13.5
The new price is 13.50
