Stephanie rode her new moped to Rod's house. Traveling the side streets, she avaraged 20 mph. To save time on the return trip, t
Illusion [34]

Answer: the distance traveled on the return trip is 70 miles.

Step-by-step explanation:

Let d represent the distance travelled along the side streets.

Let t represent the time spent travelling along the side street

Traveling the side streets, she avaraged 20 mph.

Distance = speed × time

Therefore, distance travelled along the side streets is

d = 40t

On the return trip, Rob's truck took the freeway, averaging 50 mph. The freeway distance is 2 miles less than the distance on the side streets and they saved 24 minutes(24/60 = 0.4 hours). It means that the distance travelled on the return trip is (d - 2) miles and the time spent is

(t - 0.4) hours. Therefore

d - 2 = 50(t - 0.4)

d - 2 = 50t - 20 - - - - - - - - - - -1

Substituting d = 40t into equation 1, it becomes

40t - 2 = 50t - 20

50t - 40t = - 2 + 20

10t = 18

t = 18/10 = 1.8

d = 40t = 40 × 1.8

d = 72

The distance on the return trip is

72 - 2 = 70 miles.

Find the product of (x + 5)(x - 5).<br> x2 - 10x + 25<br> x2 + 10x + 25<br> x2 - 25<br> x2 + 25
Mekhanik [1.2K]

Answer:

x²-25

Step-by-step explanation:

Hi there!

We are given (x+5)(x-5) and we want to find their product.

As these are binomials, we can multiply them using FOIL, which is First, Outer, Inner, Last

So let's start with the firsts, which would be (x+5)(x-5), or the 2 x's; x*x=x²

Next, let's do the outers, which would be (x+5)(x-5); x * -5 = -5x

Now the inners; (x+5)(x-5); 5 * x = 5x
Finally, the lasts; (x+5)(x-5); 5 * -5 = -25

Now add all of these terms together:

x²-5x+5x-25

We can combine the 5x and -5x together to become x²-25

So the answer is x²-25, which is a difference of squares expression (if we have (a-b)(a+b), then the result is a²-b²).

Hope this helps! :)

Which equation would you use to find how high the bird is flying?
Kisachek [45]

Answer:

tan45 = x over 1100

Step-by-step explanation:

Because tan = opposite/ adjacent

x is the opposite of the 45 angle in the figure shown

1100 is the adjacent of the 45 degree angle

thus tan45 = x/1100
