Hello.

The answer would be <span>C. 88.4.

You have to add the total  distance (yards) and then divide it by the total time (minutes).

So you would divide 8</span>84 yards by 10 minutes to get 88.4

Have a ncie day

Average speed = (total distance covered) / (time to cover the distance)

total distance covered = (516 + 368) = 884 yards
time to cover the distance = (6 + 4) = 10 minutes

Average speed = (884 yards) / (10 minutes)  =  88.4 yds/min (C)

Write and solve an equation of ratios:

5 *10^9 years       100 m
------------------- = --------------
   5 * 10^3 yrs            x

Reducing the first fraction,
              
             100 m
10^6 = ----------
                 x
                                100 m
Solving for x,  x = ------------- = 10^(-4) m, or [10^(-1)] * [10^(-3))]
                                10^6
this comes out to one tenth of 1 millimeter.

A circle with a radius of 15.4 meters. Which statements are true about the circle shown? Check all that apply. The diameter of t
Dafna1 [17]

Step-by-step explanation:

the diameter of a circle is simply 2×radius.

2×15.4 = 30.8 m

the diameter is 30.8 m is true.

the circumference of a circle is

2×pi×radius

2×pi×15.4 = 30.8×pi m

the circumference is 30.8pi m is true.

therefore, the circumference can be found using

2(pi)(15.4)

is true.

now, doing the pi multiplication :

30.8 × pi = 96.76105373... m

the approximate circumference is 96.7 m is true.

6 diameters would be

30.8×6 = 184.8 m

that is much longer than the circumference.

so, more than 6 diameters could be wrapped around the circle is false, if we understand it that this is supposed to wrap the circle once without any overhanging remainder.
