Akhtar gets a bonus of 20% of £70Karl gets a bonus of £26
Work out the difference between the bonus Akhtar gets and the bonus Karl gets.

Answers

Answer:

Akhtar gets £12 less than the bonus Karl gets

Step-by-step explanation:

20% of £70 is £14

so, £14 - £26 = -£12
in conclusion, Akhtar gets £12 less than the bonus Karl gets

Answer:

To find the difference between the bonus Akhtar gets and the bonus Karl gets, you can follow these steps:

Calculate Akhtar's bonus:

Akhtar's bonus is 20% of £70. To find this, multiply 20% (or 0.20 as a decimal) by £70:

Akhtar's bonus = 0.20 * £70 = £14

Calculate the difference between Akhtar's bonus and Karl's bonus:

Difference = Akhtar's bonus - Karl's bonus

Difference = £14 - £26

Now, subtract £26 from £14 to find the difference:

Difference = -£12

So, the difference between the bonus Akhtar gets and the bonus Karl gets is -£12. Since Akhtar's bonus is smaller than Karl's, the difference is negative, indicating that Karl receives a higher bonus than Akhtar.

An experiment consists of three steps. There are four possible results on the first step, three possible results on the second step, and two possible results on the third step. The total number of experimental outcomes is:________. a. 9
b. 14
c. 24
d. 36

Answers

In this experiment, the probability of experimental outcomes is 24.

What is probability?

Probability is the chance of happening an incident or event. A probability is calculated by the ratio of the possible outcomes to total number of outcomes.

Given, the possible outcomes on the first step = 4.

The possible outcomes on the second step = 3.

The possible outcomes on the third step = 2.

Therefore, total number of experimental outcomes

= outcomes in first step × outcomes in second step × outcomes in third step

= 4 × 3 ×2

= 24

6x + y = 4
X - 4y = 19

Solving systems by substitution

Answers

6x+y=4
X-4y=19

You are going to want to take -4y and put it to the other side:
X-4y=19
Which is: x=4y+19
6x+y=4
Now substitute x !
6(4y+19)+y=4
Distribute it
24y+114+y=4
Now combine like terms
25y+114=4
Subtract 114 both sides
25y= -110
Y=-4.4

Now you have y so take either equation and substitute the y
X-4(1.4)=19
X+17.6=19
X=1.4
Y=-4.4
The answer is x= 1.4 y=-4.4
