Answer:
x = 20°
y = 70°
Step-by-step explanation:
the angle adjacent to the 40° angle must be 140° because the two angles form a straight line (which contains 180°)
in the isosceles triangle with the 'x', that means the other two angles must be equal and are (180-140) ÷ 2, which equals 20°
to find 'y', consider the larger right triangle with angles of 90° and 20°; angle y must equal 180 - (90 + 20) = 70°

Answer:
$27.12
Step-by-step:
So, we first need to learn how much money the tax is. We can find it like this
8.5 8.5x12.50
------ x 12.50 = ----------------
100 100
106.25
= ------------- = 1.0625 ~~ $1.06
100
The tax is $1.06
So now, the only thing left is to add
12.50 + 1.06 = $13.56
13.56x2 = $27.12 (for both gifts)
In total, both gifts cost $27.12 with tax.
In total, both gifts cost
Answer:
0.89898989.... is the correct answer
Fraction form: 
Step-by-step explanation:
0.89898989.... is the correct answer because it can be written as in the simplest form. and 0.89898989.... is rational because it is a repeating number.
Any rational number is a number that can be written as a fraction, a repeating decimal, a whole number, an integer, etc. As long as the number is a number with infinite digits like π.
L=k/r^2,
r^2 is the denominator cause L varies inversely with the square of distance
The answer is B
