x = -6

Step-by-step explanation:

4(x-6)+4=6x-8

Multiply by four in parenthesis.

4x-20=6x-8

Add 20 on both sides.

4x=6x+12

Subtract 6.

-2x=12

Divide -2

Answers

Answer:

Key for H and M. ( H-Hour)(M-Mile)

6m= h divided by 10=6

Step-by-step explanation:

6 times 10= 60 minutes. So 1 mile every 10 minutes. This was hard, but it clicked at the end. Good luck, and remember to sub out the divided and multiply by with the signs!

Answers

Answer:

Height of the tree is 40.0 meters.

Step-by-step explanation:

From ΔABC,

m∠ABC = 90°

Since, m∠ABC = m∠CBD + m∠ABD

90° = 6° + m∠ABD

m∠ABD = 90°- 6° = 84°

By triangle sum theorem in ΔABD,

m∠ABD + m∠BDA + m∠DAB = 180°

84° + 29° + m∠BDA = 180°

m∠BDA = 180° - 113°

             = 67°

By sine rule in ΔABD,

[tex]\frac{\text{sin}(\angle BDA)}{d}= \frac{\text{sin}(\angle ABD)}{h}[/tex]

[tex]\frac{\text{sin}(67)}{37}= \frac{\text{sin}(84)}{h}[/tex]

h = [tex]\frac{\text{sin}(84)\times 37}{\text{sin}(67)}[/tex]

h = 39.98

h ≈ 40.0 meters

Therefore, height of the tree is 40.0 meters.

The sine rule is the ratio of the side length to the sine of the opposite angles. Then the height of the tree is 40 meters.

What is trigonometry?

Trigonometry deals with the relationship between the sides and angles of a triangle.

Because of prevailing winds, a tree grew so that it was leaning 6º from the vertical.

At a point d = 37 meters from the tree, the angle of elevation to the top of the trees is a = 29° (see figure).

∠ABC = 90

We have

In ΔABC

∠ABC = ∠CBD + ∠ABD

∠ABD = 90 - 6

∠ABD = 84

By triangle sum in ΔABD, we have

∠ABD + ∠BDA + ∠DAB = 180

                            ∠BDA = 180 - 84 - 29

                            ∠BDA = 67

Then by the sine rule, we have

[tex]\begin{aligned} \dfrac{\sin \angle BDA}{d} &= \dfrac{ \sin \angle ABD }{h}\\\\\dfrac{\sin 67}{37} &= \dfrac{\sin 84}{h}\\\\h &= \dfrac{\sin 84} \times 37{\sin 67}\\\\h &= 39.98 \approx 40 \end{aligned}[/tex]

Elizabeth changed her time for the mile walk from 30 minutes to 24 minutes. What was the percent of change?​

Answers

-20%

Basically, we are trying to find the change from 30 to 24 in terms of percent. We do this in three steps:

1) Find the difference between 30 and 24 as a number.

2) Divide the result from Step 1 by the starting number 30.

3) Multiply the result from Step 2 by 100 to get it in terms of percent.

The three steps above can be made into a formula. Thus, to find the percent change from 30 to 24, we use this formula:

((Y-X)/X)*100 = Percent Change

X is the starting number 30, and Y is the ending number 24 that it changed to. When we enter these numbers into the formula, we get:

((24-30)/30)*100 = -20.00%

Thus, the answer to the question "What is the Percent Change from 30 to 24?" is:

-20.00%

Theodore and Sarah have a small business selling custom-made T-shirts. They currently sell 205 shirts per month and charge $15 per T-shirt. Sarah thinks they can increase their revenue by increasing their selling price, but Theodore knows from experience that each $1 increase in price will decrease the number of T-shirts they sell by 9 shirts per month. Find an expression for the total monthly revenue Theodore and Sarah's business can generate if they change the selling price of their T-shirts. Let x represent the number of $1 increases in the price of the T-shirts.

Answer:

2223

Step-by-step explanation:

We need to find the value of 2021-2223+2425.

Firstly subtract 2223 from 2021.

2021-2223 = -202

Now add -202 and 2425. So,

2425 +(-202) = 2223

So, the value of 2021-2223+2425 is 2223. Hence, this is the required solution.
