How would you explain the differences between graphing x > 4 and x ≥ 4 to a peer who missed this lesson?

Answer:

m∠S = 29.5

Explanation:

     Q

S [tex]\huge\boxed {\sf \triangle}[/tex] R

In this triangle, QR = SQ, which means its an isosceles triangle, angle S and R is similar.

Thus solve:

m∠S = (180° - 121°)/2

m∠S = 29.5°

∆QRS is isosceles

So

<Q=<S=121°

Answer:

K = 16

Step-by-step explanation:

64 / 4 = 16

Answer:

k = 16

Step-by-step explanation:

Find k if 64 ÷ k = 4

64 / k = 4

64 / 4 = k

k = 16

The fraction of the fence completed in one hour at a rate of  [tex]\frac{2}{5}[/tex] of the

fence in  [tex]\frac{3}{4}[/tex] hours is  [tex]\frac{8}{15}[/tex].

The fraction of the fence completed in [tex]\mathbf{\frac{3}{4}}[/tex] of an hour = [tex]\frac{2}{5}[/tex]

Required:

The fraction of the fence the student completes per hour;

Solution;

The time [tex]\mathbf{\frac{2}{5}}[/tex] of the fence is completed =  [tex]\frac{3}{4}[/tex] of an hour

Therefore;

[tex]The \ in \ \mathbf{\frac{\dfrac{3}{4} \ hour}{\dfrac{3}{4} \ hour}} = 1 \ hour \ the \ frraction \ completed = \dfrac{\dfrac{2}{5} }{\dfrac{3}{4} \ hour} = \dfrac{8}{15} \ per \ hour[/tex]

The fraction of the fence completed per hour = [tex]\underline{\frac{8}{15}}[/tex]

Step-by-step explanation:

A. First, convert 30 minutes to a hour.

[tex] \frac{30 \: mins}{1} \times \frac{1 \: hour}{60 \: mins} = 0.5 \: hours[/tex]

[tex]4 + 0.5 = 4.5 \: hours[/tex]

Now, we can subsitue.

Part A: 1.

[tex]d(t) = 6 + 5.5 \cos( \frac{\pi}{6}(4.5) ) [/tex]

[tex]d(t) = 6 + 5.5 \cos( \frac{3\pi}{4} ) [/tex]

Part B:

Answer:

-10(2x + 1/5)

~

1/2(x -4)

Step-by-step explanation:

-10(2x + 1/5)

Distribute -10 to all terms within the parenthesis by multiplying:

-10 * 2x = -20x

-10 * 1/5 = -10/5 = -2

-20x - 2 is your answer.

~

1/2(x -4)

Divide 2 to all terms within the parenthesis:

(x - 4)/2 = (x/2) - (4/2) = (x/2) - 2

[tex]\frac{x}{4} -2[/tex] is your answer.

Answer:

Here's an equation 9 (x+2)
Here's the answer to that equation 9x+18

Step-by-step explanation:

You basically multiply 9 times (x+2) but since you don't know what x is you multiply 9  to each number (or variable) individually. So 9(x) + 9(2). The resulting equation is 9x + 18

[tex]9(x+2)[/tex]
[tex]9(x)+9(2)[/tex]
[tex]9x + 18[/tex]

x = 5, AB = 14, BC = 8

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

Explanation:

The triangles are similar, which can be proven through the angle angle theorem.

The similar triangles allow us to form the proportion below.

EB/DB = AB/BC

7/4 = (2x+4)/(x+3)

7(x+3) = 4(2x+4)

7x+21 = 8x+16

21-16 = 8x-7x

5 = x

x = 5 is part of the answer

Then we can use that x value to find the following

AB = 2x+4 = 2*5+4 = 14 is the length of AB

BC = x+3 = 5+3 = 8 is the length of BC

[tex]\frac{7}{20}[/tex] or 0.35

Step-by-step explanation:

[tex]\frac{3}{4} * \frac{7}{20} \\3*7=21\\4*15=60\\\frac{21}{60} \\[/tex]

Now simplify.

[tex]\frac{21}{60}[/tex] = [tex]\frac{7}{20}[/tex]

Step-by-step explanation:

step 1: add the ratios

1/2 + 1/4 + 1/5 = 0.95

step 2: divide each ratio by the total sum of the ratios and multiply by a 100

(1/2 ÷ 0.95) × 100 = 52.63 rounded off equals to 53

(1/4 ÷ 0.95) × 100 = 26.31 rounded off equals to 26

(1/5 ÷ 0.95) × 100 = 21.05 rounded off equals to 21

These ratios should add up to a 100

so the ratio are 53 : 26 : 21

Answer:

part a: is c

part b: $33.25

Step-by-step explanation:

PART A: I did 6x68.45=410.70

8x39.71=317.68

3x52.25=156.75

410.7+317.68+156.75=885.13

so the closest thing to it is c

PART B: i did

5x2.89=14.45

10x9.91=79.10

48x0.36=17.28

14.45+79.10+17.28=110.83

144.08-110.83=33.25

so the case of air fresheners was $33.25

Answer:

x=21°

Step-by-step explanation:

in the isosceles triangle, if two sides are equal,then the angles opposite those sides are equal.

so, 2x=42° ( exterior angle of a triangle is equal to the sum of the two opposite interior angles)

x=21°

Answer: y = x - 4

Step-by-step explanation:

Slope intercept form is y = mx + b

    Given:

-2x = -8 -2x

    Add 2x and 2y to both sides of the equation:

2y = 2x - 8

    Divide both sides of the equation by 2:

y = x - 4
