Well, first let's identify which answers are incorrect, then it will be easier to figure out which are correct.
A. Equilateral: An equilateral triangle is a triangle with 3 equal sides. Since there are 180 degrees in a triangle, an equilateral triangle would have three sides of 60 degrees, and none of 45 degrees. Answer? Incorrect.
B. Isosceles: An isosceles triangle has two sides that are equal. 45 and 45 are equal, therefore, this answer is: Correct!
C. Scalene: A scalene triangle has three unequal sides, therefore, this answer is incorrect.
D. Obtuse: An obtuse triangle has one angle that is more than 90 degrees, therefore, since 45 and 45 equal 90 already, this answer is: incorrect.
E. Right: A right triangle has one right angle (angle that equals 90 degrees) since 45 + 45 = 90, and 90 + 90 = 180, this answer is: Correct!
F. Equiangular: This last choice is practically the same as the first, therefore the answer is: incorrect.
The two correct answers are: B Isosceles, and E Right!
Answer:
B 9
Step-by-step explanation:
Use the rule of exponents for a division. To divide two powers with the same base, write the same base and subtract the exponents.
Now do it with your numbers.
Answer: B 9
There’s a 30% difference between the percent of increase and percent of decrease. There is a 50% increase when it goes from 30 to 45. And a 20% decrease from 45 to 36.
Answer:
3/4
Step-by-step explanation:
There are 4 cards total
The card not less than 6 are 6,7,8 = 3 cards
P( not less than 6) = number of cards not less than 6 / total
= 3/4
