Mathematics

liubo4ka [24]3 years ago
5 0

Answer:

The probability is 1/4.

Step-by-step explanation:

To find the probability of two events occurring, find the probability of each event and multiply the two probabilities:

The probability of 1 coin landing on tails is 1/2.

The probability of another coin landing on tails is 1/2.

Multiply the probabilities:

1/2 * 1/2 = 1/4

Write a real world problem you could answer by solving the equation -8+60=28
aksik [14]

<em>"Mitchael owes $8 to his bank, so he decides to add $60 in April at a rate of $2 per day. How many days Mitchael needs in order to get $28 in his account?"</em>

<h2>Explanation:</h2><h2 />

Hello! Remember you have to write clear questions in order to get good and exact answers. The given equation doesn't make any sense so I'll assume the correct one is:

-8+60x=28

So let's write a real world problem you could answer by solving the equation:

<em>"Mitchael owes $8 to his bank, so he decides to add $60 in April at a rate of $2 per day. How many days Mitchael needs in order to get $28 in his account?"</em>

So by isolating x (number of months):

x=\frac{28+8}{60} \\ \\ x=0.6 \ month \\ \\ \\ Since \ we \ need \ the \ number \ of \ days: \\ \\ April \ has \ 30 \ days, \ so: \\ \\ x-day=0.6\times 30=18 \ days

So Mitchael would need 18 days in order to get $28 in his account

Help me plz find the value of x for which QR is parallel to RS
erik [133]

Given:

QR is parallel to RS.

To find:

The value of x.

Solution:

In the given figure, we have,

PR=12

RT=2x-2&#10;

QS=21

ST=3x-1

Using basic proportionality theorem (BPT), we get

\dfrac{PR}{RT}=\dfrac{QS}{ST}

\dfrac{12}{2x-2}=\dfrac{21}{3x-1}

On cross multiplication, we get

12(3x-1)=21(2x-2)

36x-12=42x-42

36x-42x=12-42

-6x=-30

Divide both sides by -6.

x=\dfrac{-30}{-6}

x=5

Therefore, the value of x is 5.
