akin has some money in a box.if 3/8 of the money Is N4.80, how much money does he have in the box​

Answers

Answer:

N12.8

Assume the money in the box Is M.

therefore, 3/4 of M=N4.80.

Recall N1=100k..... where k 'kobo'

N4.80=X

X=4.80x100. this gives us 480k.

this implies that 3/4 X M= 480k

therefore by cross multiplication, and dividing by 3; 3M=480 X 4

M = (480 X 4) ÷3

M=1280k

converting from kobo' to Naira. the rate of conversion is;

100k = N1

1280k=?

M in naira= 1280/100

M is N12.8

What is the probability of spinning a yellow?
What is the probability of spinning an odd number?
What is the probability of spinning a number less than 5?

Answers

Answer:

Answer given below

Step-by-step explanation:

P (spinning yellow) = 2 / 8 = 1 / 4

P (Spinning an odd number) = 4 / 8 = 1 / 2

P ( spinning a number less than 5) = 4 / 8 = 1 / 2

Hope it helps

The probability of spinning a yellow is 1/4.

The probability of spinning an odd number is 1/2.

The probability of spinning a number less than 5 is 1/2.

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

From the spinner

Blue region = 3

Red region= 1

Yellow region = 2

Purple region = 2

So, the probability of getting Yellow

P (spinning yellow) = 2 / 8

                                = 1 / 4

and, the probability of getting odd number

P (Spinning an odd number) = 4 / 8

                                               = 1 / 2

and, the probability of getting less than 5

P ( spinning a number less than 5) = 4 / 8

                                                         = 1 / 2

solve equation 1 for y: - y = 7 - 4x; divide by -1 to simplify into y = -7 + 4x

Substitute - 7 + 4x into the second equation to obtain:

3(-7 + 4x) - 12x = -21, which yields:

-21 + 12x - 12x = -21, which simplifies 0 = 0

What is the slope of line a?

Answers

Given:

The graph of a line a.

To find:

The slope of the line a.

Solution:

Slope formula:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

From the given graph it is clear that the line a passes through the points (-1,1) and (0,-2). So, the slope of the line a is:

[tex]m=\dfrac{-2-1}{0-(-1)}[/tex]

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

[tex]m=-3[/tex]

The slope of the line a is -3. Therefore, the correct option is C.

Answer:

Step-by-step explanation:

I am assuming you mean tan^2 theta.

The adjacent side of the triangle drawn in Q 4 = 3 (as cos theta = 3/5.

The opposite side of the triangle drawn in Q 4 = sqrt(5^2-3^2) = 4.

The tangent is negative in Q 4

So tan theta = -4/3.

tan^2 theta = 16/9.

Find the argument of the complex number z=1+iv3

Answers

Given:

The complex number is:

[tex]z=1+i\sqrt{3}[/tex]

To find:

The argument of the given complex number.

Solution:

If a complex number is [tex]z=x+iy[/tex], then the argument of the complex number is:

[tex]\theta=\tan^{-1}\dfrac{y}{x}[/tex]

We have,

[tex]z=1+i\sqrt{3}[/tex]

Here, [tex]x=1[/tex] and [tex]y=\sqrt{3}[/tex]. So, the argument of the given complex number is:

[tex]\theta =\tan^{-1}\dfrac{\sqrt{3}}{1}[/tex]

[tex]\theta =\tan^{-1}\sqrt{3}[/tex]

[tex]\theta =\tan^{-1}\left(\tan \dfrac{\pi}{3}\right)[/tex]

[tex]\theta =\dfrac{\pi}{3}[/tex]

Therefore, the argument of the given complex number is [tex]\theta =\dfrac{\pi}{3}[/tex].

What are the intercepts of y = 4x − 2?

A. (2, 0) and (0, 0.5) B. (2, 0) and (0, 5) C. (2, 0) and (0, -2) D. (0.5, 0) and (0, -2)

Answers

Answer:

D. (0.5, 0) and (0, -2)

Step-by-step explanation:

We have the following equation:

[tex]y = 4x - 2[/tex]

x-intercept:

The x-intercept of an equation is the value of x when [tex]y = 0[/tex]. So

[tex]y = 0[/tex]

[tex]4x - 2 = 0[/tex]

[tex]4x = 2[/tex]

[tex]x = \frac{2}{4}[/tex]

[tex]x = 0.5[/tex]

So (0.5,0) is one of the intercepts

y-intercept:

The y-intercept of an equation is the value of y when [tex]x = 0[/tex]. So

[tex]y(0) = 4(0) - 2 = 0 - 2 = -2[/tex]

So (0, -2) is the other intercept.

The correct answer is given by option D.
