Answer:
Alternate interior: angle 2 and angle 13
Vertical: angle 12 and angle 15
Alternate exterior: angle 5 and angle 10
No relationship: angle 1 and angle 16
Corresponding: angle 14 and angle 16
Consecutive interior: angle 4 and angle 11
Step-by-step explanation:
let the price of 6 hats be x
and price of 7 t shirts be x+6
x+x+6=$86
2x=86-6
x=80/2
x=40
price of 6 hats=40
price of a hat =40/6=$6.33
price of 7 t shirts =40+6
price of a t shirt = 46/7 =$6.57
Answer:
1680 ways
Step-by-step explanation:
We have to select 6 different integers from 1 to 10. It is given that second smallest integer is 3. This means, for the smallest most integer we have only two options i.e. it can be either 1 or 2.
So, the selection of 6 numbers would be like:
{1 or 2, 3, a, b, c ,d}
There are 2 ways to select the smallest digit. Only 1 way to select the second smallest digit. For the rest four digits which are represented by a,b,c,d we have 7 options. This means we can chose 4 digits from 7. Number of ways to chose 4 digits from 7 is calculated as 7P4 i.e. by using permutations.
According to the fundamental rule of counting, the total number of ways would be the product of the individual number of ways we calculated above. So,
Total number of ways to pick 6 different integers according to the said criteria would be = 2 x 1 x 840 = 1680 ways
No because a circle has an infinite number of lines of symmetry.
