Answer:

Yes, Renaldo will be reach on time for his Soccer practice.

Step-by-step explanation:

For traveling for 3.2 miles bus takes 30 minute times.

So, traveling a 1-mile bus will take 30 ÷ 3.2 minutes.

Now, Renaldo reaches the dentist's office at 4:30 p.m.

Then he has an appointment for 1 hour

So, Renaldo leaves the dentist's office at 5:30 p.m.

Now he has to travel 4.8 miles, it will take time = 4.8\times\frac{30}{3.2} = 45 minutes

So, Renaldo will reach Soccer field at

5 hours 30 minute + 45 minutes = 6 hours 15 minutes = 6:15 p.m

Hence, Renaldo will reach Soccer field before 6:30 p.m.

Paul drove 225 miles to visit his parents. The graph below shows the distance traveled and the total time of the trip. Write and
ziro4ka [17]

50mph

Step-by-step explanation:

The image of the motion of Paul's derive is attached already.

From the line graph we can obtain a lot of information that will help us unravel the average speed of Paul within the given time frame.

What is average speed?

 Average speed is the rate of change of total distance covered with time taken .

Average speed = \frac{total distance }{time}

To find the total distance covered;

 Distance at time 1 = 75miles

  Distance at time 4 = 225miles

Distance covered between 1 - 4 = 225 - 75 = 150miles

Time taken for the journey = 4 - 1 = 3hrs

Input the values in the equation;

   Average speed = \frac{150}{3} = 50mph

30 POINTS HELP ANSWER ASAP AND EXPLAIN STEP BY STEP HOW TO SOLVE The two non-parallel sides of an isosceles trapezoid are each 7
weeeeeb [17]
See diagram
I wrote that the degrees are 70 each because it is isocolese and 140/2=70


a.
to solve for the diagonal, I'm going to use trig to find the height and the base then use pythagorean theorem to find the diagonal

so
see I've drawn an auxiliry line to make a right triangle on the leftmost side
so
we want to find the height and base
sin(70°)=h/7
so 7sin(70°)=h≈6.57785

cos(70°)=base/7
so 7cos(70°)=base≈2.39414

now
the entire long base is 22, so that big triangle with the diagonal as the hyptonuse is 22-2.39414=19.6059
use pythagorean theorem, like 6.57785²+19.6059²=diagonal²
we get that the diagonal is about 20.68ft




b.
we got that the base was 7cos(70°)
2 of those bases so 22-14cos(70°)=17.2117ft or rounded 17.21ft




a. 20.68ft
b. 17.21ft
