Answer:

The amount of water must be added to this task = 60 cm^{3}

Step-by-step explanation:

Let amount of water added = x cm^{3}

Then from the given conditions

A chemist would like to dilute a 90-cc solution that is 5% acid to one that is 3% acid. So

90 (0.05) = 0.03 ( 90 + x )

4.5 = 2.7 + 0.03 x

0.03 x = 1.8

x = 60 cm^{3}

Therefore the amount of water must be added to this task = 60 cm^{3}

Ralph Chase plans to sell a piece of property for ​$160,000. He wants the money to be paid off in two ways monica ​short-term no
DerKrebs [107]

Answer:

  • short-term: $90,000
  • long-term: $70,000

Step-by-step explanation:

Let x represent the amount borrowed on the short term. Then 160000-x is the amount of the long-term note. The total interest is ...

  0.11x +0.08(160000-x) = 15500

  0.03x + 12800 = 15500 . . . . simplify

  0.03x = 2700 . . . . . . . . . subtract 12800

  x = 2700/.03 = 90,000 . . . . short-term note

  160,000 -90,000 = 70,000 . . . . long-term note

The short-term note was for $90,000; the long-term note was for $70,000.

Which best describes the relationship between the two triangles below?
Nostrana [21]

Answer:

They are SIMILAR triangles

Step-by-step explanation:

Given triangles MNL and FHG with two of their angles to be 51° and 36° respectively. Their third angle is expressed as:

180°-(51°+36°)

= 180°-87°

= 93°

Their third angle is 93°

Since both triangles have the same angles in them, both triangles are considered as similar triangle even though the value of their sides are different due to angle differences in both.

Note that individual triangles are scalene triangles since their angles are not the same but the both triangles are similar triangles based on their relationship.
