Answer:
I got 7%
Step-by-step explanation:
110 x .15 = 16.5
110-16.5=93.5
93.5 x .10 = 9.35
93.5 + 9.35= $102.82
Thats the discount price
110 - 102.82 + 7.18
7.18/102 = .0698
.0698 x 100 = 6.98
7%
I have this on my middle school test and it's my first time doing it so yea. I hope it helps even if it's already too late.
I had to edit it beforee
180/3x then you get you answer
Yo sup??
a.For this part just draw a triangle with sides 4,8 and 8 inches respectively.
The sides having 8 inches should make equal angle with the base side.
b.One angle is 20
The other two angles be x and y
but x=y because its an isosceles triangle
x+y+20=180
2x=160
x=80
Hope this helps.
Answer:
Yes, they will be.
Step-by-step explanation:
Congruent means when they are the same shape and same size.
If triangle ABC is dilated to <u><em>form</em></u> triangle DEF, that means that they will have the same shape and the same size.
So yes Triangles ABC and DEF will be congruent to one another because they will be the same shape, and they will have the same size as well.
Hope this helped!

Answer:
x = 2 + 6i, x - 6i.
Step-by-step explanation:
To factor this you need 2 numbers whose product is + 40 and whose sum is -4. There are no such numbers so we could use the method of completing the square:
x^2 - 4x + 40 = 90
x^2 - 4x = -40
(x - 2)^2 - 4 = -40
(x - 2)^2 = -36 - So the roots are complex numbers:
x - 2 = +/-√36
x = 2 + 6i, x - 6i.
