Answer: The answer would be
D - 12.25x + 3.99 = 77.49
Step-by-step explanation:
If each shirt costs $12.25, that would be 12.25 times “x” amount of shirts. Then, you add the $3.99 shipping amount. Which all equals 77.49.
Answer:
Options (A), (B)
Step-by-step explanation:
Option A.
Two sides of the given triangle are equal. Therefore, the given triangle is an isosceles triangle.
Option (B).
Given triangle has a right angle. Therefore, it's a right triangle.
Option (C).
Only two sides of the given triangle are equal. Therefore, it's not an equilateral triangle.
Option (D).
Although this triangle has two acute angles (less than 90°) but the third angle is 90°. Therefore, this triangle is not an acute triangle. It's a right triangle.
Option (E).
A scalene triangle is a triangle having all sides different in measure but the given triangle is an isosceles triangle. Therefore, it's not a scalene.
Option (F).
Any angle of this triangle is not more than 90°. Therefore, the given triangle is not an obtuse triangle.
The price now is (80/100)x70 = (5600/100) = $56;
The answer to this question would be: A.13
In this question, the mean is 20.2 and the standard deviation is 2.4. That means the range for of 1 standard deviation would be 20.2 +- 2.4= 17.8- 22.6
The number that included in that range would be 18-22. Then you just need to add them all
18 =2
19 =3
20 =4
21 =3
22 =1
The answer would be: 2+3+4+3+1 = 13
