To the nearest hundredth, which is the value of x in the solution of the following system? 3.5x - 2.8 = -4.67x + 12.5 Select one: a. -3.75 b. -1.87 c. 1.87 d. 3.75

Answers

Answer:

C. 1.87

Step-by-step explanation:

3.5x - 2.8 = -4.67x + 12.5

3.5x + 4.67x = 12.5 + 2.5

8.17x = 15.3

x = 15.3 ÷ 8.17

x = 1.87270501836

So, the closest choice to 1.87270501836 is 1.87, so the answer is C.

Hence, the answer would be C. 1.87. I am 100% sure on this, for I am a pro.

A. 7 divided by 2

Step-by-step explanation:

The computation is shown below;

[tex]= 6\frac{3}{4} \div 1 \frac{2}{3} \\\\= \frac{27}{4} \div \frac{5}{3}\\\\= \frac{27}{4} \times \frac{3}{5}\\\\= \frac{27\times 3}{4\times 5} \\\\= \frac{81}{20} \\\\= 4 \frac{1}{20}[/tex]

It could be 4.05

So according to the given options, the option 1 is chosen at is closed to 4.05

2. y is inversely proportional to cube of x.
When x = 2, y = 4.
Find y when x = 4
(3 Points)

Answers

Answer:

y = 0.5 at x = 4

Step-by-step explanation:

According to question,

y is inversely proportional to cube of x i.e.

[tex]y\propto \dfrac{1}{x^3}\\\\y=\dfrac{k}{x^3}[/tex]

or

[tex]k=yx^3[/tex]

Put x = 2 and y = 4 in above expression to find k.

[tex]k=4\times (2)^3\\\\=32[/tex]

Now put x = 4 to given equation to find y.

[tex]y=\dfrac{32}{4^3}[/tex]

y = 0.5 or 1/2

So, the value of y is 0.5 when x = 4.

The shadow of a vertical tower is 52.5 meters long when the angle of elevation of the sun is x degrees. The height of the tower is 41 meters. Find the angle of elevation rounded to the nearest degree.

Answers

Answer:

Angle of Elevation = 38°

Step-by-step explanation:

Angle of Elevation formula is given as

tan x = Opposite /Adjacent

Where

x = Angle of Elevation

Opposite = Height of the tower = 41 meters

Adjacent = Shadow of the vertical tower = 52.5 meters

Hence:

tan x = 41 m/52.5m

x = arc tan (41 m/52.5m)

x = 37.988141726°

Approximately to the nearest degree x = 38°
