A video game displays 132 frames in 6 seconds on Penelope's computer. What is the rate in frames per second?
juin [17]

Answer:

unit\ rate=22\ frames\ per\ second

Step-by-step explanation:

we know that

To find the unit rate , divide the total frames by the total seconds

Let

x ----> the total frames displayed by the video game

y ----> the total seconds

unit\ rate=\frac{x}{y}

we have

x=132\ frames\\y=6\ seconds

substitute the values

unit\ rate=\frac{132}{6}=22\ frames\ per\ second

Find the perimeter of the figure to the nearest hundredth.
babunello [35]

Answer:

50.28 inches

Step-by-step explanation:

From the Image, we can find the length of the arc of the semi-circle by dividing the circumference of the resulting circle by 2

Radius= 9in

C= 2πr

C=2*3.142*9

C=2*3.142*9

C= 56.556 inches

Hence the length of the arc is

=56.556/2

=28.278 inches

The perimeter of the shape

=28.278+5+12+5

=50.28 inches
