Answer: C and D
Step-by-step explanation:
20% is equal to 0.2. And if we're adding from the previous day it's 1 whole + 0.2, which is 1.2. Times the variable.
And 1/5 is equal to 0.2. So its the variable and 20% added again.

Shelby purchases DVDs from a website. Each DVD costs $11, and the shipping and handling fees are $6.95. Shelby is charged a total of $50.95. How many DVDs did she purchase?
Answers
DVD cost , $11 .
Shipping and handling fees , $6.95 .
Total money charged , $50.95 .
Let , total money is T .
So,
[tex]11x+6.95=T[/tex] ( Here x is number of DVD )
[tex]11x+6.95=50.95\\\\11x=44\\\\x=4[/tex]

✦ First you need to know the area of a triangle:
✧ ½ x b x h
✦ Now write you formula out:
✧ ½ x 5 x 4
✦ Now just solve:
✧ 5 x 4 = 20
✧ 20 / ½ = 10
So it'd be 10 m²

Answer:
the opposite of a negative number is positive.
Step-by-step explanation:
Negative numbers are numbers that are less than 0. The opposite of a positive number is negative, and the opposite of a negative number is positive. Since the opposite of 0 is 0 (which is neither positive nor negative), then 0 = 0.

Tara is 2 years older than Ryan. The sum of their
ages is greater than 58. Describe Ryan’s age.
Answers
Ryan = 28 years
Tara = 30 years
Ryan is over 28 years old.
Step-by-step explanation:T = R + 2
T + R = 58
Replace T
(R + 2) + R = 58
2R = 56
R = 56 : 2
R = 28 years
T = 30 years
Solve the right triangle. Side AB is 2.9, but I don't know how to find two missing angles with three sides and a 90-degree angle. Please explain your answer.
Answers
Angle A = 68 degrees
Angle B = 22 degrees
Side AB = 2.9 cm
The three values are approximate
=========================================================
Explanation:
a = BC = 2.7 and b = AC = 1.1 are the two legs of the right triangle.
Use the pythagorean theorem to find the length of the hypotenuse
a^2 + b^2 = c^2
2.7^2 + 1.1^2 = c^2
8.5 = c^2
c^2 = 8.5
c = sqrt(8.5)
c = 2.91547594742266
c = 2.9
The hypotenuse is c = AB = 2.9
--------------------
We then use trig ratios to find the two missing angles.
Let's say we ignore the hypotenuse and focus on the two legs of the triangle.
With respect to reference angle A, side BC is opposite and AC is adjacent
Use the tangent ratio to get
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = 2.7/1.1
tan(A) = 2.45454545454546
A = arctan(2.45454545454546)
A = 67.8336541779176
A = 68
Note: arctan is the same as inverse tangent or [tex]\tan^{-1}[/tex]. Make sure your calculator is in degree mode.
-------------------
Similarly,
tan(angle) = opposite/adjacent
tan(B) = AC/BC
tan(B) = 1.1/2.7
tan(B) = 0.4074074074074
B = arctan(0.4074074074074)
B = 22.166345822082
B = 22
Or you could use the value of A to get B = 90-A = 90-68 = 22. This works because A+B = 90 as we're working with a right triangle. In other words, A and B are complementary angles.
-------------------
In summary we found
A = 68
B = 22
AB = 2.9

lou thinks the expression 27x^3-64 factors to (3x-4) (9x^2+12x+16). is he correct? How can you check his work? Show all work to justify your thinking.
Answers
Answer:
Step-by-step explanation:
(a³ - b³) = (a - b) (a² + ab + b²)
27x³ - 64 = 3³x³ - 4³
= (3x)³ - 4³ {a = 3x & b= 4)
Substitute in the above formula.
= (3x -4)([3x]² + 3x*4 + 4²)
= (3x - 4)(9x² + 12x + 16)
The expression 27x^3-64 factors to (3x-4) (9x^2+12x+16).

if a=120 degrees find the measures of b,c, and d
Answers
Answer:
<b=120°,<c=60° & <d=60°
Step-by-step explanation:
Here,
given that <a=120°
<a is vertically opposite to <b
We know,vertically oppposite angles are equal
So,<a=<b=120°
<a & <c lies on a straight angle.
So,<c=180°-120° (Sum of two angles on a straight angle is 180°)
<c=60°
Again,<c is vertically opposite to <d.
So,<d=60°.
