Answer:
57.1428571429 miles per hour <em>Round off the answer to what your teacher asked.</em>
Step-by-step explanation:
Since we want final answer in miles per hour, lets change the 30 mins to 0.5 hours
Phase 1 =25miles per 0.5 hours
Phase 2 = (200miles-25miles) per 3 hours
Speed = distance/time
Average speed = total distance/ time
Total distance is 200miles because both phases say from new york that means it travels 25 miles away from new york then 3 hours later it is 200 miles away from new york
total time =3 hours+0.5 hours = 3.5 hours
Average speed = 200/3.5
Average speed = 57.1428571429 miles per hour

We know that
<span>Monica can walk 3.8 kilometers in 40 minutes
and
</span><span>she can jog twice that distance in the same amount of time
that means
in 40 minutes Monica can jog (3.8 km*2)-----> 7.6 km
1 hour=60 minutes
</span>by proportion<span>
7.6 km/40 minutes=x km/60 minutes
x=7.6*60/40----> x=11.4 km
the answer is
11.4 km</span>
To simplify a fraction, you must find a number both the numerator and denominator can be divided into, and divide. Say I have 4/6. Both numbers are divisible by 2, so I simplify the fraction to 2/3. As we can no longer divide, the fraction is in simplest form. Hope this helps!
The area of circle can be found using the formula πr² and since we know that semi circle is half the circle so its formula will be 1/2πr².
First we will find the radius.
20/2 = 10
Radius is 10.
A = 1/2(3.14)(10)²
A = 157
Hope this helps :)
The value for r is mathematically given as
r<-82
This is further explained below.
<h3>What are inequalities?</h3>
In mathematics, an inequality is a relation that compares two numbers or expressions in a way that is not equal. The most common use is doing a size comparison between two numbers on a number line.
Generally, eighty-two less than r is less than −164 is mathematically given as
r-82 <-164
r<-82
Therefore
r<-82
