Answer:
Assuming this has something to do with the interior angles of a triangle?
98 + 50 + x = 180, add 98 and 50.
148 + x = 180, subtract 148 from both sides.
x = 32
I need help finding the slope, The y-intercept, and the equation??
The cost of a pair of pants was reduced from $50 to $40. By what percent did the cost of the pair of pants decrease? 2% 10% 20% 40%
Answer:
C. 20%
Step-by-step explanation:
50*2=100
40*2=80
100-80=20
A percentage is a number or ratio that represents a fraction of 100.
The percentage decrease in the cost of the pair of pants is 20%.
What is a percentage?A percentage is a number or ratio that represents a fraction of 100.
Example:
50% = 50/100 = 1/2
10% = 10/100 = 1/10
25% = 25/100 = 1/4
20% = 20/100 = 1/5
We have,
The initial cost of pair of pants = $50
The final cost of pair of pants after reduced = $40
The percentage decrease in the cost of pair of pants:
= [( Initial cost - Final cost ) / Initial cost] x 100
= [(50 - 40) / 50] x 100
= (10/50) x 100
= 20%
Thus,
The percentage decrease in the cost of the pair of pants is 20%.

Many states run lotteries to raise money. A website advertises that it knows "how to increase YOUR chances of Winning the Lottery." They offer several systems and criticize others as foolish. One system is called Lucky Numbers. People who play the Lucky Numbers system just pick a "lucky" number to play, but maybe some numbers are luckier than others. Let's use a simulation to see how well this system works. To make the situation manageable, simulate a simple lottery in which a single digit from 00 to 99 is selected as the winning number. Any value can be picked, but for this exercise, pick 1 as the lucky number. What proportion of the time do you win

Any value can be picked, but for this exercise, pick 1 as the lucky number. What proportion of the time do you win?
Answer:
10%
Step-by-step explanation:
We are told that To make the situation manageable, simulate a simple lottery in which a single digit from 0 to 9 is selected as the winning number.
This means the total number of single digits that could possibly be a winning one is 10.
Since we are told that only 1 can be picked, thus;
Probability of winning is; 1/10 = 0.1 or 10%

were 12 chocolates remaining in the box. Write an equation for C, in terms oft,
representing the number of chocolates remaining in the box t days after Zoe's
birthday.
Answer:
c=-3t+30
Stay safe
The expression for the number of chocolates remaining will be c = 24 - 4t.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that, Zoe was given a box of assorted chocolates for her birthday. Each night, she to some chocolates. Zoe ate 4 chocolates each night and after 3 nights, there were 12 chocolates remaining in the box.
Let the number of days be represented by t, and the number of chocolates will be C.
The total number of chocolates will be calculated as,
Total = 3 x 4 + remaining chocolates = 12
Total = 3 x 4 + 12
Total = 12
The expression will be written as,
C = 24 - 4t
Therefore, the expression for the number of chocolates remaining will be c = 24 - 4t.

The factored form of a quadratic function is f(x)=(x-p)(x-q).The standard form of a quadratic function is fX)=ax^2+bx+c. The factored
form for a quadratic function tells us the x-intercepts of the quadratic function, while the standard form for a quadratic function tells us they
intercept of the quadratic function.
If p=2 and q=-3, use what you have learned about multiplying polynomials to
1) write the factored form of the quadratic function f(x)
2) write the standard form for the quadratic function f(x)
Answer:
(1) f(x)=(x-2)(x-3)
(2) f(x)=x²-5x+6
Step-by-step explanation:
(1) f(x)=(x-p)(x-q)
f(x)=(x-2)(x-3)
(2) f(x)=x²-3x-2x+6
f(x)=x²-5x+6
