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:

12 days

3 degrees

Step-by-step explanation:

Let y be the temperature of the cities after x days have passed.

Temperature of New York City

[tex]y=-3+\dfrac{1}{2}x[/tex]

In Juneau the temperature falls by 1 degree per 4 days. So, in 1 day the temperature falls be [tex]\dfrac{1}{4}[/tex] degree.

The minus sign is due to the fact that the temperature is falling

Temperature in Juneau Alaska

[tex]y=6-\dfrac{1}{4}x[/tex]

We need to find the value of x for which y will be equal

[tex]-3+\dfrac{1}{2}x=6-\dfrac{1}{4}x\\\Rightarrow \dfrac{1}{2}x+\dfrac{1}{4}x=6+3\\\Rightarrow \dfrac{3}{4}x=9\\\Rightarrow x=\\\Rightarrow x=9\times \dfrac{4}{3}\\\Rightarrow x=12\ \text{days}[/tex]

[tex]y=-3+\dfrac{1}{2}x=-3+\dfrac{1}{2}\times 12\\\Rightarrow y=3\ \text{degrees}[/tex]

Hence, in 12 days the temperature will be same in both the cities will be 3 degrees.

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

Step-by-step explanation:

5x = 24 and  24/5 = x

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

The minimum number of hours is 5/6 and the inequality is x ≥  5/6 hours.

An inequality is a relationship that compares two numbers and perhaps other mathematical expressions that are not equal. It is most commonly used to compare the sizes of two numbers on a number line.

Let x = the number of hours practicing the drums

we know that Julian needs to spend at least seven hours each week practicing

the drums x ≥ 7  hours

He has already practiced 5*(1/3) hours this week.

Convert mixed number to an improper fraction 5*(1/3)  = 16/3hours.

Subtract 16/3 from 7,

7 - (16/3)

= 5/3

Divide 5/3 by 2,

(5/3)/2

=5/6

Hence,

The inequality that represent the minimum number of hours he needs to practice on each of the two days is x ≥  5/6 hours.

The correct number line is one with value at 1, facing the right and unshaded

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]

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].

The original cost of Sam’s investment is $10,000

Sam calculated his real return to be $10,700

Required:

the interest made from the investment is

10700-10000= $700

Step two:

The ROI is a percentage that tells us the interest made

interest/investment*100

=700/10000*100

=0.07*100

= 7%

The ROI is 7%

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.

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.

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.

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/
