Find the value of x. Round to the nearest tenth.

Use this to find the value of x: tan (x) = 4/3

Answers

Using tan(x) = 4/3

X = arctan(4/3)

X = 53.1 degrees

Answer:

Step-by-step explanation:

tan x = 4/3

tan x=1.333333

divide both sides by tan

x=1.33333/tan

x=tan inverse of 1.33333

x=53.130

x=53.13 to the nearest tenth

The ratio of girls to boys in a swimming club was 2 : 4. There were 14 girls. How many total members were there in the club?

Answers

Answer:

42

Step-by-step explanation:

the ratio 2:4 can be reduced to 1:2,

where the number of girls corresponds to the 1 and the number of boys corresponds to the 2.

If there are 14 girls, then there must be 28 boys (14 x 2 = 28).

Now to get the total number we need to add the total number of boys and girls together.

So 14 + 28 = 42

Hope it helps :)

Answer:

32

Step-by-step explanation:

14 + 28 = 32

2 x 7 = 14

4 x 7 = 28

find the particular solution to the exact differentiable equation dy/dx=(2e^x)-cosx passing through the point (0,3)

Answers

Answer:

y = 2eˣ - sin x + 1  

Step-by-step explanation:

dy/dx = 2eˣ - cos x

(0, 3)

Integrate dy/dx to find the original function.

y = 2eˣ - sin x + C

Solve for C by substituting the point given.

3 = 2e⁰ - sin(0) + C 3 = 2 - 0 + C 1 = C

Now we can substitute C into the original function.

y = 2eˣ - sin x + 1  

This is the particular, or explicit, solution to the differentiable equation.

Answer:

x < 3

(*￣3￣)╭

Answer:

The answer is x < 3.

Step-by-step explanation:

1) Simplify 3x - 3 - 6 to 3x - 9.

[tex]0 > 3x - 9[/tex]

2) Add 9 to both sides.

[tex]9 > 3x[/tex]

3) Divide both sides by 3.

[tex] \frac{9}{3} > x[/tex]

4) Simplify 9/3 to 3.

[tex]3 > x[/tex]

5) Switch sides .

[tex]x < 3[/tex]

Therefor, the answer is x < 3.

John took a taxi from his house to the airport. The taxi company charged a pick-up fee of $4.70 plus $2.50 per mile. The total fare was $24.70, not including the tip. How many miles was the taxi ride? ​

Answers

Answer:

8

Step-by-step explanation:

You can solve this by creating a linear equation.

Slope: 2.50

Y-intercept: 4.70

y=2.50x+4.70

Since we know that the total fare was 24.70 we can plug it into the y.

24.70=2.50x+4.70

Now solve for the equation.

20=2.50x

8=x

So he went 8 miles with the taxi.

Total number or mile taxi run is 8 miles.

Given that;

Pick up charge = $4.7

Charges per mile = $2.5 per mile

Total fare = $24.7

Find:

Number of mile taxi ride

Computation:

Total fare = Pick up charge + [Total number or mile taxi run][Charges per mile]

24.7 = 4.7 + [Total number or mile taxi run][2.5]

[Total number or mile taxi run][2.5] = 24.7 - 4.7

[Total number or mile taxi run][2.5] = 20

Total number or mile taxi run = 20 / 2.5

Total number or mile taxi run = 8 miles

solve for x
(21x-9)
27
x=​

Answers

Answer:

x = 6

Step-by-step explanation:

∠ AFB and ∠ EFC are vertically opposite angles and are congruent , then

21x - 9 = 117 ( add 9 to both sides )

21x = 126 ( divide both sides by 21 )

x = 6

The measured valued of x is 6.

What are Vertical Angle?

Vertical angles are generated by the junction of two straight lines that are not contiguous. Vertical angles are positioned across from each other in the corners of the "X" created by two straight lines.

We have,

<AFB = 21x- 9

and, <DFC = 27

Using Vertical Angle

<AFB = (<EFD + <DFC)

21x - 9=  (90 + 27)

21x - 9 = 117

21x = 117 + 9

21x = 126

x = 6
