Answer:7 Feet below ground

Step-by-step explanation:

1st: Since it says our hole is dug down 8ft to begin with we can start with x=-8

2nd: After a short break, it says we dug down another 3 feet which is -8-3=-11 which shows we are 11 feet below ground where the negative number showcases we are below ground level.

3rd:

After this we are shown a tractor accidentally fills in the hole with 4ft of dirt which signifies that we lose some of our holes height below ground so we would add four: -11+4=-7 this shows that we are finally seven feet below ground.

Travka [436]

Answer:

0.395

Step-by-step explanation:

The computation of the probability that none of the three shoppers purchased electronics is shown below:

So, first we have to determine the number of shoppers without considering the purchase i.e

= Total number of shoppers - electronics

where,

Total number of shoppers = Offices supplies + electronics + clothing + beauty supplies - electronics

= 18 + 25 + 40 + 12 - 25

= 95 - 25

= 70

Now the probability is

= \frac{70}{95}\times\frac{69}{94}\times\frac{68}{93}

= 0.395

A triangle is such that the largest angle is 3 times the smallest angle. The third angle is 23 less than the largest angle. Find
Leokris [45]

largest angle:  3x

smallest angle:  x

third angle:  3x - 23

The sum of the angles of a triangle equals 180°

(3x) + (x) + (3x -23) = 180

7x - 23 = 180

7x = 203

x = 29

largest angle:  3x  = 3(29)  = 87

third angle:  3x - 23   = 3(29) - 23   = 87 - 23   = 64

Answer: 29°, 64°, 87°
