Answer: The equation can be written as 8n = 99.2.
Step-by-step explanation:
In my answer, I used the variable n to distinguish itself as one side of the stop sign. 99.2 is the final perimeter in inches.
A stop sign is an octagonal shape (otherwise, it is made up of 8 equal sides). Therefore, with this information, you can interpret that the length of one side would be equal to the length of all of the other sides.
Hence, the answer can be represented as 8n = 99.2.
Answer:
acute angle measure less than 90 degrees, right angle measure 90 degrees, Obtuse angle measure more than 90 degrees, straight angle equal to 180 degrees, reflex angle is an angle greater than 180° and less than 360°, complementary angle either of two angles whose sum is 90°, supplementary angle either of two angles whose sum is 180°
Answer:
2340
Step-by-step explanation:
(-12)×(13)×(-15)
=(-156)×(-15)[ (+) × (-) = (-)]
=2340[(-) × (-) = (+)]
Answer:
160 miles
Step-by-step explanation:
Distance = speed × time
Speed 1 = 40miles/hr , speed 2 = 50 miles/hr
Time 1 = 3 hrs, time 2 = 4 hrs
Distance 1 = speed 1 × time 1
= 40× 3 = 120 miles
Distance 2 = speed 2 × time 2
= 50 × 4 = 200 miles
Average distance = (distance 1+distance 2 ) ÷ 2
Distance = (200+120) ÷ 2 = 320 ÷2
= 160 miles
