Martina Is Currently 18 Years Older Than Her Cousin Joey. In 5 Years She Will Be 3 Times As Old As Joey

Answers

Answer 1

Answer:

The age of Joey is 4 years  and

The age of Martina is 22 years .

Step-by-step explanation:

Given as :

Martina is 18 years older than her Joey

In 5 years, Martina will be three times older than Joey

Let The age of Martina = M years

And The age of Joey = J years

Now, According to questions

M = J + 18          ........1

(M+5) = 3 × (J+5)

Or, M + 5 = 3 J + 15

Or, M - 3 J = 15 - 5

∴ M - 3 J = 10                ..........2

Solving eq 1 and 2

Put the value of M from eq 1 into eq 2

So, (J + 18) - 3 J = 10

Or, J - 3 J = 10 - 18

Or, - 2 J = - 8

∴ J =

i.e J = 4 years

So, The age of Joey = J = 4 years

Now, Put the value of J in eq 1

So, M = J + 18

Or, M = 4 + 18

∴ M = 22 years

So, The age of Martina = M = 22 years

Hence,The age of Joey is 4 years  and The age of Martina is 22 years . Answer

Calculate the current in an Inductor if the energy stored is 240J and the Inductance is 24H.​

Answers

Answer:

Current, I = 4.47 Amperes.

Step-by-step explanation:

Given the following data;

Inductance = 24H

Energy stored, Eind = 240J

To find the current;

The energy stored in an inductor is given by the formula;

Eind = ½LI²

240 = ½*24*I²

Cross-multiplying, we have;

480 = 24I²

I² = 480/24

I² = 20

Taking the square root of both sides, we have;

Current, I = 4.47 Amp

Write a cosine function that has a midline of 2, an amplitude of 4 and a period of
8/3

Answers

Answer: f(x) = 4*cos(pi*(6/8)*x) + 2

Step-by-step explanation:

A generic cosine function is written as:

f(x) = A*cos(w*x + p) + M

where:

A = amplitude

w = angular frequency

p = phase

M = midline.

We know that:

the midline is 2, then  M = 2

the amplitude is 4, then A  = 4

There is no information about the phase, so p = 0.

And we know that the period is 8/3.

The period is written as T, and the relation between the period and the angular frequency is:

T = 2*pi/w

Then we have:

8/3 = 2*pi/w

w = (2*pi)*(3/8) = pi*(6/8)

where pi = 3.14

Then we have:

w =  pi*(6/8)

A = 4

M = 2

p = 0

Then the cosine function is:

f(x) = 4*cos(pi*(6/8)*x) + 2.

The probability that it is red 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.

Given:

A bag with 8 marbles

4 red marbles,

3 blue marbles,

and 1 yellow marble.

So, the probability that it is red

= 4 / ( 8)

= 1/2

Hence, the probability that it is red is 1/2.

What is a triangle?

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

x and 100° together form a straight angle.

x + 100 = 180

x = 180 - 100

x = 80

Now,

45° + x + y = 180

45 + 80 + y = 180

y = 180 - 125

y = 55°

Thus,

y = 55°.
