The sales was increased by 44.4%.

Step-by-step explanation:

Lets do this cumulative
90 of 10 % = 9 which is 99
90 of 10 % = 9 which is 108
90 of 10% = 9 which is 117
90 of 10% = 9 which is 126
90 of 4 % = 3.6 which is 129.6
90 of 0.044% = 0.0396 which is 129.99
This comes to nearly 44.44 to be closer there was an increase.
Always rule 1 approximation use 50% of 90 if it is above 130.
Down it to 40% of 90 see if the sales is lower than 130.
It should always start with 50,40,30....10 percents.
Alternative should be 10,1 or decimals.
Approximation using decimals rounding up becomes simple.

Answer: If order does not matter then we can use following formula to find different combinations of 6 numbers out of 46 numbers

Step-by-step explanation: Use following Combination formula

nCr = n! / r!(n-r)!

n=46

r=6

=46!/6!(46-6)!

=46!/[6!(40)!]

=(46*45*44*43*42*41*40!)/(6*5*4*3*2*1)(40!)

Cancel out 40!

=46*45*44*43*42*41/(6*5*4*3*2*1)

=6744109680/720

=9366819

1) Working alone, Beth can tar a roof in 151

Pachacha [2.7K]

Answer:

A) 7.24 hours

Step-by-step explanation:

The together rate is the sum of each separate rate.

In this problem:

Beth's rate is 1/15(suppose there was a small typing mistake there, with 151 none of the options are correct).

Mike's rate is 1/14

The together rate is 1/x

Then

We want to find x.

$\frac{1}{15} + \frac{1}{14} = \frac{1}{x}$

15*14 = 210. So

$\frac{14 + 15}{210} = \frac{1}{x}$

$\frac{29}{210} = \frac{1}{x}$

Cross multiplication

$29x = 210$

$x = \frac{210}{29}$

$x = 7.24$

So the correct answer is:

A) 7.24 hours

Carly mowed 2 more lawns than Rocco each week for 6 weeks. Carley mowed a total of 18 lawns. How many lawns did Rocco mow each w

Reptile [31]

Rocco mowed 1 lawn a week.

You wanna divide Carley’s total mowed lawns by the amount of weeks she mowed for.
18/6 = 3
Carley mowed 3 lawns a week.
We’ll take away two from that because she mowed two more that Rocco each week, resulting in Rocco mowing one lawn a week.
Hope this helps!! :))
