What two numbers multiply to negative 54 and add up to 3

DENIUS [597]

The roots of 54 are: 1 and 54, 2 and 27, 3 and 18, 6 and 9, then it restarts all over again.

The two numbers have to multiply up to 54, and add up to 3. 9 and 6 have a difference of 3, and the multiplied sum is negative, so this is your pair.

9 and -6 fit this criteria, since they add up to 3 and multiply to 64.

Find the mean and mode for this set of data. 5,6,8,3,5,7,4,11,5,7

katrin [286]

The mode is what number occurs most often. So in this set, the number that occurs most often is 5.

Mode = 5

The mean is the average of all the numbers in the set. To find the average of numbers, you add them all up then divide by how many numbers there are in the set. 5 + 6 + 8 + 3 + 5 + 7 + 4 + 11 + 5 + 7 = 61. 61 divided by 10 = 6.1 The answer is 6.1

Mean = 6.1

Good luck, my guy!

will works 7 hours a day, 6 days a week. he is paid 9.20 an hour. he shares is wages with his mum in the ratio will:mum 5:2

vredina [299]

Answer:

7 weeks.

Step-by-step explanation:

Will works 7 hours a day, 6 days a week. So total number of hours worked by Will is,

$=7\times 6=42$ hours

He earns £9.20 an hour, so total money earned in a week by Will will be,

$=42\times 9.20=\£386.4$

As he shares with his mother in a ration of 5:2, so he gets 2 parts out of 7 parts. (as 5+2=7)

So the actual amount saved by Will is,

$=386.4\times \dfrac{5}{7}=\£276$

The price of the car is £1932, so the number of week that Will will take is,

$=\dfrac{1932}{276}=7$

Which two numbers have a least common multiple of 48?

tekilochka [14]

While neither 9 nor 8 are prime numbers, the factors of 9 are 3*3 and of 8 are 2*2*2. Since they share no factors in common, their product will be the least common multiple. (Multiples of 9 are 18, 27, 36, 45, 54, 63, and 72; Multiples of 8 are 16, 24,32, 40, 48, 56, 64, and 72).
