Angle B and angle C are supplementary If the measure of angle B is 14 times the measure of angle C, what is the difference between
the angles measures
Pls help asap
Answer:
The difference between the angle measure is 152 degrees
Step-by-step explanation:
Supplementary angles are angles that add up to 180
So if one angle is x in this case, the other will be 14x
Adding both ;
x + 14x = 180
15x = 180
x = 180/15
x = 12
The other angle is 14 * 12 = 168
The difference between the two will be;
168-12 = 156

Stan has $95. He wants to buy as many movies as he can. All movies are originally
$12.00 and are on sale for 10% off. Tax is 5%
Answer:
Step-by-step explanation:
Each movie is $12.00. 10% off of 12% is 12-1.2 = 10.8
The final amount spent is 5%, that means we can multiply the end amount spend by 1.05
The maximum Stan can spend is $95
[tex](10.8m)*1.05\leq 95\\(10.8m)\leq 90.4762\\m \leq \frac{90.4762}{10.8}\\m\leq 8.3774[/tex]
Now, you can't buy 0.3 of a movie, so the most Stan can buy is 8 movies

Here are the first four terms of an arithmetic sequence. 3 10 17 24 Find, in terms of n, an expression for the nth term of this arithmetic sequence.
Answer:
[tex]a_{n}[/tex] = 7n - 4
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 3 and d = a₂ - a₁ = 10 - 3 = 7 , thus

Lakita wants to go to trade school and study electronics for a two-year program. Her tuition and books will cost about $5,500 per year. She will also spend about $100 a month commuting from her parents’ house to school. How much will her education cost her in total?
Answer:
$13,400
Step-by-step explanation:
Given the following data;
Tuition and book per year = $5,500
Transportation per month = $100
In 2 years;
Total tuition and book = $5,500 * 2 = $11,000
Total tuition and book cost = $11,000
Transportation;
There are 12 months in a year, in 2 years = 12 * 2 = 24 months.
Thus, total on transportation = $100 * 24 = $2,400
Total transportation cost = $2,400
[tex] Overall \; cost = Total \; tuition \; and \; book \; cost + Total \; transportation \; cost[/tex]
Substituting into the above equation, we have;
Overall cost = $11,000 + $2,400
Overall cost = $13,400.
Hence, Lakita's education will cost her $13,400 in total.

graph the inequality
Answer:
y > 1/2x - 1
First, draw the dashed line y = 1/2x - 1 (slope intercept ; y = mx + b).
Start at -1 on the y-axis, and continue going 2 units to the right, and 1 unit up for the right side of the graph.
Then starting at -1 on the y-axis, continue going 2 units to the left, and 1 unit down for the left side of the graph.
Explanation:
Convert standard form (Ax + By = C) by isolating y from the rest of the equation.
Ax + By = C → y = -Ax/B + C/B → y = mx + b.
Given a standard form equation in inequality form,
x - 2y < 2.
Set it to slope-intercept as an inequality to find the slope and y-intercept.
When negating (making opposite) a variable, you flip the inequality.
x - 2y < 2 → x - 2y - x < 2 - x → -2y < -x + 2 → 2y > x - 2 → y > 1/2x - 1.

Use the Remainder Theorem to determine whether or not x + 3 is a divisor of p (x) = 2x^3 + 4x^2 - 2x + 12
PLEASE SHOW WORK.
Step-by-step explanation:
This is answer. I'm sri lankan. But our a/l exam have this mathematics questions
The remainder when the polynomial p(x) = 2x³ + 4x² - 2x + 12 is divided by x + 3 is -6.
A polynomial is an expression consisting of the operations of addition, subtraction, multiplication of variables.
The remainder theorem states that for a polynomial, f(x) divided by a linear polynomial , x - a, the remainder is equal to f(a).
Given the polynomial; p(x) = 2x³ + 4x² - 2x + 12, since it is divided by x + 3, hence:
x + 3 = 0
x = -3
p(-3) = 2(-3)³ + 4(-3)² - 2(-3) + 12 = -6
Hence the remainder when the polynomial p(x) = 2x³ + 4x² - 2x + 12 is divided by x + 3 is -6.

i) because it is a parallelogram AC=OB and therefore AC=b
to find OC you do OA+AC which is a+b
OC=a+b
ii) to find BA you do BO+OA
BO=-b as it is the opposite direction
OA=a
so therefore BA=a-b
iii)CA is the opposite of AC which was b so CA=-b

Answer:
The measurement of largest angle is 83°
Step-by-step explanation:
Given angles are:
(2x+1)° , (x+15)° and x°
The sum of internal angles of a triangle is 180°
We will use this sum to find the value of x first
[tex](2x+1)+(x+15)+x = 180\\2x+1+x+15+x = 180\\4x+16 = 180\\4x = 180-16\\4x = 164\\\frac{4x}{4} = \frac{164}{4}\\x = 41[/tex]
Now the measurement of angles are:
x = 41
[tex]2x+1 = 2(41)+1 = 82+1 =83\\x+15 = 41+15 = 56[/tex]
Hence,
The measurement of largest angle is 83°
