Answer:
z=20.8
x=16.97
y=12
Step-by-step explanation:
The triangle on the right is a 30,60,90 triangle, a special right triangle with simple rules to find the side lengths. sides A,B, and C where C is the hypotenuse (24 in your diagram). The short side A is= 1/2 of side C (12 in your diagram). The long side B is= side A*√3 (20.8 in your diagram).
The triangle on the left is another special right triangle called a 45,45,90. The rules for this triangle are C= A*√2, and B=A. Because of the rules in the 30,60,90 triangle, we know that side A is 12. This means that side B (y)=12. Side C (x)= 16.97.
Hope this helped! Sorry if my explanation is confusing, but the rules for special right triangles can be easily found online and then calculated :)
Answer:
y=-4x-24
Step-by-step explanation:
The equation of a line is always in the form y=mx+c. By subbing in the values given by the two points, we get:
0=-6m+c
-24=c
∴0=-6m-24
6m=-24
m=-4
∴the equation is: y=-4x-24
Total time = 10/10
So time left = 10/10 - 2/10 - 7/10
= 10/10 - 9/10
= 1/10 (answer)
If you use a calculator its easy
16.72 - 1.24 = 15.48
15.48 divided by 12 is 1.29
for sales tax 1.24 divided by 12 is .10
so for each one She spent $1.39
