Verizon [17]3 years ago
6 0

Answer:

The inequality to determine the number of rotations is given by

 r ≤ 5.25

Therefore the maximum number of rotations possible is 5.

Step-by-step explanation:

i.) The bottom of Ignacio's desktop is  74.5 cm from the floor.

ii.) The tops of his legs are 49.3 cm from the floor.

iii.) the difference between the bottom of Ignacio's desktop and the top of his legs = 74.5  - 49.3 = 25.2 cm.

iv.) Each clockwise rotation of the knob on the chair raises Ignacio's legs by 4.8 cm.

v.) let the number of clockwise rotations be r.

vi.) therefore the inequality to determine the number of rotations is given by

  4.8r ≤ 25.2     therefore r ≤ 25.2/4.8    therefore r ≤ 5.25

Sonja [21]

Answer:

1/6

Step-by-step explanation:

People who answered less than 1/2 were:  2 +  1 + 3 = 6 people.

There are a total of 36 people.

People who answered their calls before the second ring were only 6/36.

When we simplify the fraction, we get 1/6.

So, the answer is 1/6.

castortr0y [4]
 
<span>∵ There is a proportional relationship between the mass and the volume of the places of metal.
Let volume = v and mass = m
So, the relation between volume and mass will take the form:
        v = km
where k is constant and can be calculated as follow:
when m = </span><span>34.932 , and v = 4.1   ⇒⇒⇒ k = v/m = 0.117371
</span>when m = 47.712<span> , and v = 5.6   ⇒⇒⇒ k = v/m = </span>0.117371
when m = 61.344 , and v = 7.2   ⇒⇒⇒ k = v/m = <span>0.117371
when m = </span>99.684 , and v = 11.7  ⇒⇒⇒ k = v/m = <span>0.117371

∴ v = 0.117371 m
</span>
For  v =<span>15.3
∴ m = v/k = 15.3/0.117371 = 130.356 </span><span>gram

</span>The mass of a piece of this metal that has a volume of 15.3 cubic centimeters ≈ 130.4 gram (<span>round to the nearest tenth</span>)
