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:

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:

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

x > 1

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

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].

================================================

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]

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

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

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 )
