How shall i find the square root of 169 without using calculator?? please describe briefly..
kvv77 [185]
Without experience that would help you recognize it right away, I think
you would just need to try numbers until you find it.

Pick a number, multiply it by itself with pencil and paper, and see if it works.

(2)² = 4     too small
(3)² = 9     too small, and not growing fast enough; this could take all day 
(10)² = 100    still too small
(15)² = 225    oops, too big; go back down
(12)² = 144    too small
(14)² = 196    too big
(13)² = 169    just right;  hope the bears don't come back too soon

8. Suppose Betty saves $200 each month in her 401(k) account. How much less will her monthly take-home pay be? (Assume a combine
Dominik [7]

Note: Check the file attached below for the complete question

Answer:

Betty's monthly take home is $20 less

Step-by-step explanation:

Betty's monthly income = $2300

Betty's monthly savings = $200

Amount left after savings = $2300 - $200

Amount left after savings = $2100

Federal and State Income tax rate = 20% = 0.2

Tax amount paid = $420

Monthly take home = $2100 - $420

Monthly take home = $1680

Compared to $150 per month savings, Betty's monthly take home is $20 less

Designer Dolls, Inc., found that the number N of dolls sold varies directly with their advertising budget A and inversely with t
denis-greek [22]

here we are told that

number of dolls sold varies directly with advertising costs

number of dolls varies inversely with price of a doll


so initially

1800 dolls sold when advertising costs were $ 34 000

and price of a doll was $ 25


next they increased the advertising costs to $ 42 000

as we know number of dolls sold varies directly with advertising costs

so here when the advertising costs increase the number of dolls sold too should increases as its directly proportional relationship


we arent told that the price of a doll is changed so there's no effect on the number of dolls sold due to changes in price of a doll


only effect on number of dolls sold is due to increase in advertising costs

increase in advertising cost leads to increase in number of dolls sold


from the given options, only in one option the number of dolls sold are more than 1800 dolls. option is C with 2224 dolls


therefore correct answer is C. 2224 dolls
