  1. What I Know
    It takes 70 minutes to mow the whole lawn.
    One location it takes 5 hours with a push mower
    90% was used to cut the lawn with the power mower and the rest with the push
    Q;How many minutes did it take him to mow the whole lawn?

    70 minutes to mow the lawn with the power mower. Its needs to mow 90% of the lawn
    0.9x70=63
    It will take 63 minutes to mow the entire lawn with the power mower.
    It takes 5 hours to mown the lawn with push mower. Now i would need to convert it to minutes.
    5x60=300
    There is 10% left.
    0.10x300=30
    It would take 30 mins with the push mower.
    63+30=93
    The whole lawn will take 93 minutes to mown that lawn.

  2. 90% of 70 is 63 so we need to add 10% of the weak mower to the 63 to get the total amount of time.

    So for the weak mower, 5x60=300 minutes to do 100% of the lawn. And 10% of that is 30.

    63+30=93 minutes. It would take 93 minutes to mow the lawn.

  8. What I know
    - it takes 5 hours to cut the entire lawn using the push mower for 70 minutes
    -90% of the lawn was used by the powerful riding mower
    -Rest was used by the push mower
    ?How many minutes did it take manny to cut the entire lawn

    Solution

    90% o f70 minutes
    90%-= 0.90
    0.90x70=x
    63=x
    It takes 63 minutes to cut 90% of the lawn with the powerful riding mower

    100%-90%=10%
    He has 10% of the lawn to mow with the push mower

    5x60=300 minutes to cut of 10% of the lawn

    10% of 300 minutes

    10%=0.10
    0.10x300=x
    30 =x
    It took him 30 minutes to cut 10% of the lawn with push mower

    63=30=93 minutes to cut the entire lawn using the powerful riding mower for 90% and push mower for 10%

  9. W.I.K

    5 HRS with push mower
    70 Mins with powerful mower
    90% cut with powerful mower the rest with push mower

    ANSWER

    I need to find 90% of 70 mins.
    0.9 X 70= 63 mins for 90%

    10 % of the lawn with push mower
    It takes 5 hrs to mow the lawn with the push mower
    i am going to change this in to minutes
    5X60=300 mins
    since this is 100 % of a lawn we need to find 10 % of this lawn
    0/.10X300= 30 mins

    now i will add both times


    63+30=93 mins


    Final answer

    it will take 93 mins to mow this lawn. 90% powerful mower and 10 % push mower.

  12. Answer:
    90% of 70
    0.90 x 70 = 63
    So it takes 63 mins to cut 90% with Power mower

    there is 10% of the lawn left to do
    90%+10%=100%
    it takes 5 hours to mow the lawn with the other mower
    5hrs is 300 minutes (5x60=300)
    we need to find the remaining 10% so...
    0.10x300= 30
    add both numbers...
    63+30=93

    It takes Manny 93 minutes to cut the entire lawn

  16. Math Problem

    WIK

    -it takes 70 mins to mow the lawn using a powerful riding mower
    -it takes 5 hours to mow the lawn using a pusher mower
    -90% was cut using a pusher mower
    -rest of the 10% of the lawn was cut using a pusher mower


    90%=0.9
    0.9x70=n
    63=n

    It took 63 minutes to mow 90% of the lawn using a powerful riding mower

    5 hours=300 minutes

    10%=0.1

    0.1x300=30 mins
    It took 30 mins to mow 10% of the lawn using a pusher mower.

    30mins+63mins= 93mins

    Therefore, it will take 93 mins to mow the whole lawn.
