Answer:

36°

Step-by-step explanation:

(6x)° + 54° = 90°

(complementary angles)

(6x)° = 90°- 54°

(6x)° = 36°

[tex]x = \frac{2y + 21}{5} [/tex]

Step-by-step explanation:

1) Add 18 to both sides.

[tex]2y + 3 + 18 = 5x[/tex]

2) Simplify 2y + 3 + 18 to 2y + 21.

[tex]2y + 21 = 5x[/tex]

3) Divide both sides by 5.

[tex] \frac{2y + 21}{5} [/tex]

4) Switch sides.

[tex]x = \frac{2y + 21}{5} [/tex]

Hope it helps.

sorry if its wrong.

The equation 2y + 3 = 5x - 18 can be rearranged to make x the subject as x = (2y + 21) / 5.To make x the subject of the equation 2y + 3 = 5x - 18, we need to isolate x on one side of the equation.

Let's rearrange the equation step by step:

2y + 3 = 5x - 18

First, let's move the constant term (-18) to the other side by adding 18 to both sides:

2y + 3 + 18 = 5x

2y + 21 = 5x

Next, we can divide both sides by 5 to isolate x:

(2y + 21) / 5 = x

Therefore, the equation 2y + 3 = 5x - 18 can be rearranged to make x the subject as x = (2y + 21) / 5.

Answer:

41 mph (miles per hour)

Step-by-step explanation:

Answer:

.34

Step-by-step explanation:

Khan

The required value of probability P(130< x < 150) is 0.34.

A Z-score is stated as the fractional model of data point to the mean using standard deviations.

here, z = x - μ / σ

where, μ = mean and σ = standard deviation

Here,
From the quesiton put value in z score formula,
z = 130 - 150 / 20
z = -1

P (z < - 1) = P(x<130) = 0.15866

P (x > 130) = 0.84134
Now,
P(130< x < 150) = 0.5 - P(x<130)
P(130< x < 150) = 0.5 - 0.15866 = 0.34134

Thus, the required value of  P(130< x < 150) is 0.34.

Step-by-step explanation:

Here, we want to find the approximate solution to the system of linear equations

We start by plotting the graph of the lines

We have the plot as shown below;

the red line represents the first equation while the blue line represents the second equation

We have the solution as the point at which the two lines meet

The solution to this is;

Explanation:

The value of k determines the slope, or rate of change, of how fast the balloon is climbing per second.

For example, if k = 5, then that means the balloon is going upward at 5 feet per second (equivalent to roughly 3.41 mph)

If k = 5, then y = kt becomes y = 5t. Note how we have the following

and so on. Each time t goes up by 1, d goes up by 5. This is one way to see how the speed is 5/1 = 5 ft per second.

Answer:

8.12

Step-by-step explanation:

We obtain the distance between x and y

d = sqrt[(x2 - x1)² + (y2 - y1)²]

d = sqrt[(1 - 2)² + (2 - 6)²]

d = sqrt[1 + 16)

d = sqrt(17)

d² = 17

From Pythagoras rule;

Hypotenus = sqrt(Adjacent² + opposite²)

Hence,

Hypotenus = sqrt(17 + 7²)

Hypotenus = sqrt(17+ 49)

Hypotenus = sqrt(66)

Hypotenus = 8.124

Hypotenus = 8.12

c. -11

d. -9

Step-by-step explanation:

if x is less than -2, then u have to use the equation 5(x)-1

if x is greater than or equal to -2, then you have to use the equation (x)-9

Answer:

Step-by-step explanation:

This is a ‘piece wise function’ meaning it has different functions depending on the value of the independent variable, x.

So for questions a and b where x<-2 you sub the x value into the top equation, 5x-1.

f(-4)=5(-4)-1=-20-1=-21

f(-3)=5(-3)-1=-15-1=-16

Since the second two x values are not less than -2, you sub the x values into the second equation x-9

f(-2)=-2-9=-11

f(0)=-0-9=-9

Answer:

x = 3 and x = 8

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, then

WA = DR , substitute values

12x - 9 = 5x + 12 ( subtract 5x from both sides )

7x - 9 = 12 ( add 9 to both sides )

7x = 21 ( divide both sides by 7 )

x = 3

------------------------------------------------------

The diagonals of a parallelogram bisect each other, then

QS = [tex]\frac{1}{2}[/tex] QT , that is

Step-by-step explanation:

x = -35,814 ft ⋅ (1 sec)/(-4 ft) = 8,953.5 sec

The required model suggests that it would take approximately 8957.5 seconds for DeepSea Challenger to reach the bottom.

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

To find the time it takes for the DeepSea Challenger to reach the bottom, we need to find the value of x when y = -35,814 ft.

We can substitute the desired depth into the equation y = -4x:

-35,814 = -4x

35,814 = 4x

x = 35,814 / 4

x = 8953.5 seconds

So, the model suggests that it would take approximately 8957.5 seconds for DeepSea Challenger to reach the bottom.
