Answer:
) ''You need to consider 200^o = 180^o + 20^o , hence you need to use the next formula to evaluate sin 200^o in terms of k:
sin (alpha + beta) = sin alpha*cos beta + sin beta*cos alpha
Plugging alpha = 180^o , beta = 20^o in the formula yields:
sin 200^o = sin (180^o + 20^o) = sin 180^o*cos20^o + sin 20^o*cos 180^o
Plugging sin 180^o = 0 and cos180^o = -1 in the formula yields:
sin 200^o = - sin 20^o = -k''

Let the total number of problems be x.
After 15 minutes, [tex]x-\frac{1}{4}x=\frac{3}{4}x[/tex] problems are left.
After another 15 minutes, [tex]\frac{3}{4}x\left(1-\frac{1}{3})=\frac{3}{4}x\left(\frac{2}{3} \right)=\frac{1}{2}x[/tex] problems are left.
This is equal to 12, meaning x = 24.

Write the equation of a line that passes the point (-6,9)and is perpendicular to a line that passes through the points (-2,1) and (6,7).
Answer: y = -(4/3)x + 1
Step-by-step explanation:
Let's start with finding an equation of a straight line (y=mx+b) that goes through points (-2,1) and (6,7).
The slope of a line, m, is the change in y for the change in x, or Rise/Run.
This is derived from the two points.
Rise (7-1) = 6
Run (6 - (-2)) = 8
Rise/Run = 6/8 or 3/4
The line is therefore y = (3/4)x + b
Find b by using one of the two points. I'll use (-2,1), but the other would also work.
y = (3/4)x + b
1 = (3/4)(-2) + b
1 = -(6/4) + b
b = 10/4
The line becomes y = (3/4)x + 10/4
--------
A line perpendicular to this will have a slope that is the negative inverse of the original line. The negative inverse of (3/4) is -(4/3).
The perpendicular line will be:
y = -(4/3)x + b
Use point (-6,9) to find b:
y = -(4/3)x + b
9 = -(4/3)*(-6) + b
9 = (24/3) + b
b = (27/3 - 24/3) = 3/3 = 1
The line is y = -(4/3)x + 1

4x = 34×10
x= 340/4
x= 85
the value of x is 85
Answer:
85 copies
Step-by-step explanation:
Number of copies for $4 = 10
Number of copies for $1 = 10 ÷ 4
Number of copies for $34 = [tex]\frac{10}{4}*34[/tex]
= 5*17

Answer:
hi robertlyonsdamron the answer will be B
Step-by-step explanation:
You can use the order of operations to evaluate the expression. Perform the subtraction inside the parentheses: two minus three equals negative one. Evaluate the exponents: two to the sixth power is sixty-four. Multiply and divide in order from left to right: Twelve point six times negative one equals negative twelve point six, and sixty-four divided by four is sixteen. Add and subtract in order from left to right: Negative twelve point six plus sixteen equals three point four.

M is the midpoint of PQ. MQ=5x+8 and PQ = 6x+56, find PM
Answer:
PM = 58
Step-by-step explanation:
The question tells us that the full line has a value of 6x+56. The midpoint divides this line into equal pieces. We are also given the value of half (MQ) of the line (5x+8). By subtracting 5x+8 from 6x+56, we can figure out the value of the other half of the line (PM).
This gives us the expression for PM: x+48
Now, since these are both the two parts of the midpoint, by definition, we know they're equal.
You equal both equations and get x=10
You plug in 10 as x in the expression we got for PM (10+48), which gives us the value 58.

Solving Two Step Equations
9x + 6/3 = 5x + 2
Answer:
x = 0
Step-by-step explanation:
In this case it isn't exactly 2 steps, but you can still solve it.
First, simplify. Divide 6 with 3:
9x + (6/3) = 5x + 2
9x + 2 = 5x + 2
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 2 and 5x from both sides:
9x (-5x) + 2 (-2) = 5x (-5x) + 2 (-2)
9x - 5x = 2 - 2
4x = 0
Divide 4 from both sides of the equation to isolate the variable, x:
(4x)/4 = (0)/4
x = 0/4 = 0
x = 0 is your answer.

Tavon has a gift card for $170 that loses $4 for each 30-day period it is not used. He has another gift card for $150 that loses $3.50 for each 30-day period it is not
used
a. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal
b. What will the value of each card be when they have equal value?
Answer:
37
Step-by-step explanation:
It will take twenty 30-day periods until the value of the gift cards will be equal. The value of each card when they have equal value is $10
What is an expression?
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Let x represent the number of 30-day periods until the value of the gift cards will be equal.
Tavon has a gift card for $90 that loses $4 for each 30-day period it is not used. This means that x 30-day periods, the amount left would be
90 - 4x
He has another gift card for $ 80 that loses $3.50 for each 30-day period it is not used. This means that x 30-day periods, the amount left would be
80 - 3.5x
For the amounts left on each card to be the same, the number of periods would be
90 - 4x = 80 - 3.5x
90 - 80 = - 3.5x + 4x
10 = 0.5x
x = 10/0.5
x = 20
The value of each card when they have equal value is
90 - 4 × 20 = 90 - 80
= $10
Therefore, It will take twenty 30-day periods until the value of the gift cards will be equal. The value of each card when they have equal value is $10
