What is the value of N?
Answer:
85
Step-by-step explanation:
Since the exterior angles of a triangle always add up to 360:
360 - 133 - 142 = 85
Step-by-step explanation:
all 3 indicated angles are outside angles of a triangle.
the sum of all outside angles of any polygon is 360°.
so,
N = 360 - 133 - 142 = 85°

Answer:
x = 185
Step-by-step explanation:
Given:
Plan A
Fixed cost = $14.80
variable cost = 10 cents per min = $0.1 per minute
Plan B
Fixed cost = $18.50
variable cost = 8 cents per min = $0.08 per minute
Computation:
Assume
Plan A cost = Plan B cost
14.80 + 0.1x = 18.50 + 0.08x
x = 185
find all values of c in the open interval (a, b) such that f'(c)=(f(b)-f(a))/(b-a)
f(x)=√(4-x), [-5,4]
================================================
Work Shown:
Compute the function value at the endpoints
[tex]f(x) = \sqrt{4-x}\\\\f(-5) = \sqrt{4-(-5)} = 3\\\\f(4) = \sqrt{4-4} = 0\\\\[/tex]
With a = -5 and b = 4, we have
[tex]f'(c) = \frac{f(b)-f(a)}{b-a}\\\\f'(c) = \frac{f(4)-f(-5)}{4-(-5)}\\\\f'(c) = \frac{0-3}{9}\\\\f'(c) = -\frac{1}{3}\\\\[/tex]
So,
[tex]f(x) = \sqrt{4-x}\\\\f'(x) = -\frac{1}{2\sqrt{4-x}}\\\\f'(c) = -\frac{1}{3}\\\\-\frac{1}{2\sqrt{4-c}} = -\frac{1}{3}\\\\[/tex]
Use algebra to solve for c
[tex]-\frac{1}{2\sqrt{4-c}} = -\frac{1}{3}\\\\\frac{1}{2\sqrt{4-c}} = \frac{1}{3}\\\\3 = 2\sqrt{4-c}\\\\2\sqrt{4-c} = 3\\\\\sqrt{4-c} = \frac{3}{2}\\\\4-c = \frac{9}{4}\\\\c = 4-\frac{9}{4}\\\\c = \frac{16-9}{4}\\\\c = \frac{7}{4}\\\\[/tex]

Instructions: Find the missing side. Round your answer to the nearest tenth.
Answer:
x ≈ 74.3
Step-by-step explanation:
Using the tangent ratio in the right triangle, that is
tan22° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{30}{x}[/tex] ( multiply both sides by x )
x × tan22° = 30 ( divide both sides by tan22° )
x = [tex]\frac{30}{tan22}[/tex] ≈ 74.3 ( to the nearest tenth )

A parabola can be drawn given a focus of (0, 2) and a directrix of y = 0. Write the
equation of the parabola in any form.
Given:
Focus of a parabola = (0,2)
Directrix: y=0.
To find:
The equation of parabola.
Solution:
The equation of parabola is
[tex]y=\dfrac{1}{4p}(x-h)^2+k[/tex] ...(i)
where, (h,k) is vertex, (h,k+p) is focus, y=k-p is directrix.
Focus : [tex](h,k+p)=(0,2)[/tex]
On comparing both sides, we get
[tex]h=0[/tex]
[tex]k+p=2[/tex] ...(ii)
On comparing y=k-p and y=0, we get
[tex]k-p=0[/tex] ...(iii)
Adding (ii) and (iii), we get
[tex]2k=2[/tex]
[tex]k=1[/tex]
Putting k=1 in (ii).
[tex]1+p=2[/tex]
[tex]p=2-1[/tex]
[tex]p=1[/tex]
Putting h=0, k=1 and p=1 in (i).
[tex]y=\dfrac{1}{4(1)}(x-(0))^2+(1)[/tex]
[tex]y=\dfrac{1}{4}x^2+1[/tex]
Therefore, the equation of required parabola is [tex]y=\dfrac{1}{4}x^2+(1)[/tex].
A pair of pants was on sale for 40% off. The sale price of the pants was $18.00. What was the original price of the pants?
Answer:
The original price of the pants was $30.
Step-by-step explanation:
Let x be equal to the original price of the pants.
Because the pants are 40% off, their final price was 60% of the original price. 60% as a decimal is 0.6. Using this information, we can set up the following equation and solve:
0.6x=18
Divide both sides by 0.6
0.6x/0.6=18/0.6
x=30

simplify to create an equivalent expression 4(3x +2) - 7x
Answer:
5x + 8
Step-by-step explanation:
To create an equivalent expression, we are going to simplify the expression as far as we can. To do this, we are going to first distribute what we can.
1. 4(3x+2) -7x
2. Distribute the 4.
3. 12x + 8 - 7x
4. Combine like terms.
5. 12x - 7x = 5x
6. 5x + 8
Draw a Picture Cynthia has a piece of wood
that is 6 feet long. She cuts it into 3-foot pieces.
How many pieces does she have? Use the
number line to help you solve the problem.
0
2
3
You may divide the entire length of the wood by the length of each piece to get how many pieces she has: 6 feet / 3 feet / piece equals two parts. Cynthia therefore has 2, 3 foot long pieces of wood.
What does math divide mean?Multiplication is the opposite of division. If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group. Creating equal groups or determining how many people are in each group after a fair distribution is the basic objective of division.
How do you multiply by four?There is a method for dividing by 4 that you can use: the the rule is to divide by 2 twice. For example, if you want to divide 12 by 4, you simply divide 12 by 2, which gives you 6, and then divide that number by 2, which, in this case, gives you 3.

A cup of cereal has 12 grams of fiber, which is 40% of the amount of fiber Jared's
doctor recommends he consume each day.
How much fiber does Jared's doctor recommend he consume each day?
Answer:
Jared's doctor recommends he consume 30 grams of fiber each day.
Step-by-step explanation:
Jared's doctor recommends he consume 30 grams of fiber each day. We know this is the answer because, if we divide 12 grams by 40%, we get 30 grams which means, 12 grams is 40% of 30 grams.
Answer:
30 grams
Step-by-step explanation:
Let the doctors recommendation be
12g = 40/100 × x
x = 12g ÷ 40/100
x = 12g × 100/40
x = 12g × 5/
x = 60g/
x = 3g
