Translate the sentence into an equation. Seven times the sum of a number and 4 is equal to 9. Use the variable b for the unknown number.

Answers

Answer 1

Answer:

7 ( b + 4 ) = 9

Step-by-step explanation:

Let the number be = b

It is given that the :

The number is added to 4.

And the value is equal to 9 when it is 7 times the sum of the number, b and 4.

Thus according to the question, the sentence can be translated in equation form as :

7 ( b + 4 ) = 9

Thus in other word, we can say that the addition of (b + 4) when it is multiplied for 7 times, we get the result as 9.

In the year 2006, a person bought a new car for $24000. For each consecutive year after that, the value of the car depreciated by 10%. How much would the car be worth in the year 2010, to the nearest hundred dollars?

Answers

Answer:

$15,746.400

Step-by-step explanation:

The computation of the car value in the year 2010 is shown below:

Since the new car brought in the year of 2006 at $24,000

And, it would be depreciation by 10%

So, in the year 2010 the car value would be

= $24,000 × (1 - 0.10)^4

= $24,000 × 0.9^4

= $15,746.400

Best luck with your studying

Answer:

x = - 3.75

y = 28.75

Step-by-step explanation:

[tex] \begin{cases} x + y = 25\\\\ 5x + y = 10 \end{cases} [/tex]

Since, x + y = 25

Therefore, y = 25 - x..... (1)

5x + y = 10......(2)

Plug y = 25 - x in equation (2), we find:

5x + 25 - x = 10

5x - x = 10 - 25

4x = - 15

x = - 15/4

x = - 3.75

Plug x = - 3.75 in equation (1), we find:

y = 25 - (- 3.75)

y = 25 + 3.75

y = 28.75

(x, y) = (-3.75, 28.75)

Answers

Answer: 89.4427

Step-by-step explanation: I apologize if I am wrong; I used Pythagorean Thyreom, and I used the formula a=√c^2-b^2 since we are solving for side a.

a=√120^2−80^2

a=√14400−6400

a=√8000

a=89.4427

What is a right-angle triangle?

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

The length of a guy's wire supporting a cell tower is 120 meters.

The guy wire is anchored to the ground at a distance of 80 meters from the base of the tower.

We know that the Pythagoras theorem.

[tex]\rm H^2 = P^2 + B^2[/tex]

We have

H = 120 m

B = 80 m

Then by the Pythagoras theorem, we have

[tex]\rm P = \sqrt{H^2 - B^2}\\\\P = \sqrt{120^2 - 80^2}\\\\P = \sqrt{14400 - 6400}\\\\P = \sqrt{8000} = 89.44[/tex]

Thus, the height of the tower is 89.44 m.
