Benone would finish mower garden in 8 hours. Pandele would finish in 10 hours mowing same garden. How long would finish mower garden together?

$Benone-(1)/(8)\ mower\ garden\ per\ hour\n\nPandele-(1)/(10)\ mower\ garden\ per\ hour\n\n(1)/(8)+(1)/(10)=(*)\n\nfind\ LCD((1)/(8);\ (1)/(10))\n\nList\ of\ the\ multiples\ of\ 8:0;\ 8;\ 16;\ 24;\ 32;\ \boxed{40};\ 48;...\nList\ of\ the\ multiples\ of\ 10:0;\ 10;\ 20;\ 30;\ \boxed{40};\ 50;\ ...\n\nLCD((1)/(8);\ (1)/(10))=40\n\n(1)/(8)=(1\cdot5)/(8\cdot5)=(5)/(40);\ (1)/(10)=(1\cdot4)/(10\cdot4)=(4)/(40)$

$(*)=(5)/(40)+(4)/(40)=(9)/(40)-together\ per\ hour$

$t-time\ when\ together\ finish\ the\ garden\n\n(9)/(40)\cdot t=1\ \ \ \ \ \ |multiply\ both\ sides\ by\ (40)/(9)\n\n\boxed{t=(40)/(9)\ (h)=4(4)/(9)\ h=4h+(4)/(9)h=4h+(4)/(9)h=4h+(4)/(9)\cdot60\ min\approx4h27min}$

In 1 hour, Benone _ _ _ g / 8 ;
In 1 hour, Pandele _ _ _ g / 10 ;

In 1 hour, Benone and Pandele _ _ _ g / 8 + g / 10 = 5g / 40 + 4g / 40 = 9g / 40;
Benone and Pandele would finish garden together in 40 / 9 hours = 4 hours 26 minutes 40 seconds;

The table represents the recommended exercise intensity for an aerobic program based on the number of visits since beginning the program.A 2-column table with 6 rows titled Intensity of Exercises. The first column is labeled Number of Visits with entries 1, 2, 3, 4, 5, 6. The second column is labeled Exercise Intensity with entries 60%, 60%, 60%, ?, ?, ?.

The program recommends a constant intensity for 3 visits, increasing intensity over 3 visits, and then decreasing intensity for 3 visits before restarting the pattern. Which sets of values could be the intensities of Amber’s exercise during the fourth, fifth, and sixth visits? Select three options.

63%, 63%, 63%
66%, 69%, 72%
66%, 62%, 58%
63%, 65%, 67%
67%, 72%, 77%

Answer:

66%, 69%, 72%

63%, 65%, 67%

67%, 72%, 77%

Step-by-step explanation:

it says that people recommend the same intensity for three then increasing for three then decreasing thus repeating this cycle

so anyways for the fourth fifthe and sixth visit itll be an increasing sensitivity

Anyways for the fourth fifth and sixth visit, it'll be an increased sensitivity.

We have given that,

What is the intensity?

The intensity or flux of radiant energy is the power transferred per unit area, where the area is measured on the plane perpendicular to the energy's propagation direction.

Hello,

1) if 5x-1>0 then |5x-1|=5x-1
==> |5x-1|<1==>5x-1<1==>5x<2==>x<2/5

2) if 5x-1<0 then |5x-1|=-5x+1
==>|5x-1|<1==>-5x+1<1==>-5x<0==>x>0
