Answer:

55 white

Step-by-step explanation:

So ratio 5:4 is essentially saying, for each 5 white marbles, there are 4 red ones. This can be represented in the equation: 5x+4x=99. We specifically want an integer solution. Because what is 1.2 of a marble? And what is -1 marbles? So as x increases by 1, the entire thing increases by 9. This gives you the equation: 9x=99 which gives you x=11. So there are 55 white and 44 red.

The constant of proportionality is 1/3

x       1        2        3        4        5        

y       3       6        9        12       15

From the question, we are to determine the constant of proportionality

The given equation is

k = x ÷ y

From the given information,

When x = 1, y = 3

∴ k = 1 ÷ 3

k = 1/3

Thus, the constant of proportionality is 1/3

Now, we will determine the values of y for the values x = 3, x = 4, and x = 5

Since

k = x ÷ y

Then,

y = x ÷ k

When x = 3

y = 3 ÷ 1/3

y = 3 × 3

y = 9

When x = 4

y = 4 ÷ 1/3

y = 4 × 3

y = 12

When x = 5

y = 5 ÷ 1/3

y = 5 × 3

y = 15

Hence, the constant of proportionality is 1/3

and three more values are

Answer:

5) x = 5

6) x = 8

Step-by-step explanation:

5) Since RT is 40 and RS is 15, ST = RT- RS=25

Since ST also equals 5x, 5x = 25 and x = 5.

6) Since ∠CBD and ∠DBA are supplementary, they add up to [tex]180^\circ[/tex], and because ∠CBD = [tex]90^\circ[/tex], ∠DBA = [tex]90^\circ[/tex].

Since ∠DBA - ∠DBE = ∠EBA, ∠EBA = [tex]90^\circ-40^\circ=50^\circ[/tex].

Step-by-step explanation:

The line [tex]y = -2[/tex] is a horizontal line.

Therefore, a line that is parallel to the given line and passes through point (-1, 1) is another horizontal line with the y-value of the point.

Therefore, the line is [tex]y = 1[/tex]

Slope-intercept form of a linear equation:

 [tex]y=mx+b[/tex]

where:

Given linear equation:

[tex]y=-\dfrac{1}{3}x+2[/tex]

Therefore, the slope of this equation is -1/3.

If two lines are perpendicular to each other, the product of their slopes will be -1.   Therefore, the slope (m) of the line perpendicular to the given line is:

[tex]\implies m \cdot -\dfrac{1}{3}=-1[/tex]

[tex]\implies m=3[/tex]

The mean of the distribution that follows the uniform probability distribution is 29.5 minutes.

The mean is the average or the most common value in a data set of numbers.

Since the distribution follows the uniform probability distribution, which is a type of probability distribution that gives all outcomes equal chances, it implies that the set of 18 values between 21 and 38 can result in a total value of 531 minutes.

The total value between 21 and 38 minutes = 531 minutes

The total number of values = 18

The average or mean = 29.5 (531/18)

By using the perimeter formula for an orthogonally oriented rectangle set on a Cartesian plane, we find that the perimeter of the figure is 68/3 units.

In this question we have a rectangle oriented with respect to the two orthogonal axes of a Cartesian plane. In this case, the vertices of the figure are of the form:

A(x, y) = (a, b), B(x, y) = (c, b), C(x, y) = (a, d), D(x, y) = (c, d)

And the perimeter of this rectangle is equal to this:

p = 2 · |a - c| + 2 · |b - d|

If we know that a = - 5, b = 2, c = 2, d = - 7/3, then the perimeter of the rectangle is:

p = 2 · |- 5 - 2| + 2 · |2 - (- 7/3)|

p = 14 + 26/3

p = 68/3

Answer:

2400 miles

Step-by-step explanation:

So the first equation is pretty straight forwards, it's in the slope-intercept form y=mx+b where m is the slope, and b is y-intercept, since as x increases by 1, the value y increases by m, which by definition is what the slope is, so m is the slope. In this context the slope is how many miles in x hours. So Space Explorer B flies 400 miles per hour. The amount of miles that Space Explorer A flies per mile can be calculated by dividing the 36400 by the 13 hours it had to travel. This gives you 2800 miles. So to find how many fewer miles Space Explorer B travels than Space Explorer A you subtract the 2 slopes. 2800 - 400 = 2400. So Space Explorer B travels 2400 fewer miles than Space Explorer A

The set that can represent an exponential function is the one in option c.

An exponential function is of the form:

So, as x increases by one unit, we multiply the previous number by b.

From the given options, the only one that can represent an exponential function is the third one:

(1, 1/2) , (2, 1/4) , (3, 1/8) ( 4, 1/16)

As you can see, as x increases, the value of y keeps being divided by 2.

This exponential function is:

[tex]f(x) = 1*(1/2)^x = (1/2)^x[/tex]

Evaluating it, we get:

[tex]f(1) = (1/2)^1 = 1/2\\\\f(2) = (1/2)^2 = 1/4\\\\f(3) = (1/2)^3 = 1/8\\\\etc...[/tex]
