Mekhanik [1.2K]3 years ago
5 0

Answer:

7000

Step-by-step explanation:

Recall the form of the difference of squares.

x^2 - y^2 = (x+y)(x-y)\\\\\\

Now let's apply it to your numbers:

85^2 - 15^2 = (85 + 15)(85 - 15)

Simplify:

(100)(70) = 7000

A vendor bought 80 pineapples ₱18.50 each. Three pineapples got rotten, but then he sold the rest at ₱25.00 each. how much did h
Hatshy [7]

Answer:

₱445

Step-by-step explanation:

₱18.50(x)

x = number of pineapples purchased

₱18.50(80) = ₱1480

80 - 3 = 77

₱25.00(z)

z = number of pineapples resold.

25.00(77) = ₱1925

₱1925 = ₱1480 = ₱445

can you give a description of the relationship between the years since the tree was transplanted and its height in inches? if so
brilliants [131]

The relationship between the years since the tree was transplanted and its height in inches is linear and represented graphically by a line with positive slope and positive y-intercept

Step-by-step explanation:

Their is a linear relation between the years since the tree was transplanted and its height in inches because

  • The tree has a constant rate of increasing of its height per year
  • Assume that the initial height of the tree when it planted is b inches
  • Its height increases m inches per year
  • Its height (y) after x years can be expressed in the formula y = m x + b

y = m x + b is the form of the linear equation, where

  • m is the slope of the graph of the equation
  • b is the y-intercept (value y at x = 0)

The relationship between the years since the tree was transplanted and its height in inches is linear represented graphically by a line with positive slope and positive y-intercept

PLEASE HELP WILL MARK BRSINLIEST!!!!!

Answer:

a) Yes

b) Not a right triangle

Step-by-step explanation:

<h3><u>Part (a)</u></h3>

The sum of the lengths of any 2 sides of a triangle is greater than the length of the 3rd side.

7 + 8 = 15 > 9

7 + 9 = 16 > 8

8 + 9 = 17 > 7

Therefore, a triangle with side lengths 7, 8 and 9 <u>can</u> be made.

<h3><u>Part (b)</u></h3>

To determine if the triangle is a right triangle, use Pythagoras' Theorem:

a² + b² = c² (where a and b are the legs, and c is the hypotenuse)

The hypotenuse is the longest side, therefore:

  • a = 7
  • b = 8
  • c = 9

Substituting these values into the formula:

⇒ a² + b² = c²

⇒ 7² + 8² ≠ 9²

⇒ 113 ≠ 81

As  7² + 8² ≠ 9²  then the triangle is <u>not</u> a right triangle.
