Answer:
27 sides.
Step-by-step explanation:
THe sum of the exterior angles in all polygons add up to 360 degrees.
So the number of angles = the number of sides = 360 / 13.333..
= 27.
(5) Angle ADC is the sum of angles ADB and BDC.
(6) Yes, because lines AG and EC form two pairs of vertical angles, including ADC and EDG, as well as ADE and CDG.
(7) Angle HJK is clearly a right angle, and a right angle has measure 90°.
20+3=23 divided by 2 ==11.5
Answer:
32
4 cups
Step-by-step explanation:
Hello there!
Speed has the following formula:
S =
, or
Speed is equivalent to
Distance divided by Time.Let's check out our problems to solve for the speed.
16.)
We have 770 miles, which is a measure of distance.
We have 120 minutes, which is a measure of time.
Let's substitute our variables with these numbers.
S =
Simplify.
S = ~6.41 Mi/min
17.)
We have 2.5 mi, which is our measurement of distance.
We have 0.5 h, which is our measurement of time.
S =
Simplify.
S = 5 Mph (When you divide by 0.5 you are multiplying the numerator by 2).
18.)
We have 244 km, our distance.
We have 2.5 h, our time.
S =
Simplify.
S = 97.6 km/h
I hope this helps!
