Answer:
95 degrees
Step-by-step explanation:
One and 4 are vertical, meaning they are congruent
4 and 8 are corresponding meaning they are congruent
8 & 7 are supplementary meaning they add up to 180 degrees

Answer: 3.905 rounded
Step-by-step explanation: The thousandth in this number is 4.
Round it up since when its 5 or more you add 1 more/raise the score
The answer is 3.905
The answer stays in school kids I'm not really sure on the answer to ask your teacher.
Answer:
Area:
4 x 4 = 16
Finding area of semi circle:
4 is your diameter so half of it is your radius which is 2 since half of 4 is 2!
2^2<---your radius being squared = 4
4(radius squared) x 3.14(pi) = 12.56
12.56 divided by 2 since its a semi circle is = 6.28
6.28 + 16 = 22.28 is your area
Perimeter is:
4 + 4 + 4 (all sides of a square are equal therefore one or two given lengths will be all the sides) = 12
Circumference:
Radius is 2,
2(you just always have to multiply this number when finding circumference) x 3.14(pi) x 2(radius), 2 x 3.14 x 2 = 12.56
12.56 divided by 2 = 6.28
6.28 + 12 = 18.28 is your perimeter.
Just a refresh:
Circumference Formula:
2(always use this number when finding circumference) x pi(3.14 or 22/7 depending on what they tell you to use for pi) x radius
Area of a Circle Formula:
Radius squared x pi(3.14 or 22/7 whatever they tell you to use for pi)
Another thing you should remember:
Whenever it gives you 1/4 of a circle or 1/3 or a semi circle or any fraction, REMEMBER TO DIVIDE BY THAT DENOMINATOR TO WHAT YOU GET FROM EITHER CIRCUMFERENCE OR AREA OF A CIRCLE!
Answer:
Total number of horses used = 16
Step-by-step explanation:
Two pony express riders each rode part of a 176 mile trip. Each rider rode the same number of miles.
They changed horses every 11 miles.
Total number of horses = Number of horses used by each pony express rider x Number of pony express rider
Total number of horses used = 8 x 2 = 16
Total number of horses used = 16
