There are two types of trees: elm and pine. There should be at least 16 total trees but no more than 30. The ratio of elm trees to pine trees will be 3:2. Give an example of how many trees of each type the designer could plan for the park. Show or explain how you found your answer.

Answers

Answer: 18 pine trees / 12 elm trees

Step-by-step explanation:

To meet the requirement of at least 16 but no more than 30 trees with a 3:2 ratio of elm to pine trees, we can choose:

Elm Trees: 3x

Pine Trees: 2x

Where x is a positive integer. To stay within the given constraints:

3x + 2x ≥ 16 (at least 16 trees)

5x ≥ 16

x ≥ 16/5

x ≥ 3.2

We need to find the largest integer value for x while staying below 30 (no more than 30 trees). Since x must be an integer, the largest valid value for x is 6 (as 7 would exceed 30).

So, for the example:

Elm Trees = 3x = 3 * 6 = 18

Pine Trees = 2x = 2 * 6 = 12

In this case, there would be 18 elm trees and 12 pine trees, totaling 30 trees, which falls within the range of at least 16 but no more than 30 trees and maintains the 3:2 ratio of elm to pine trees.

Compare partial products and regrouping how the methods are alike and different

Answers

Partial products are different in regrouping in terms of how numbers are clustered from a set equation as a whole delivering it individual but naturally to all the numbers involved in the set.
Regrouping is just like the commutative or associative property of numbers.
Associative property of addition is used when you want to group addends. This is mainly used to cluster set of numbers or in this case, addends. How do you use the associative property when you break apart addends? Simple you group them using the open and closed parentheses or brackets. Take for an example 1 + 1 + 2 = 4. Using the associative property you can have either (1 + 1) + 2 = 4 or 1 + (1 + 2) = 4 clustered into place.

Hello,

The tangential angle of mesure x intercept the same arc intercepted by the inscribed angle of mesure 70 have the same mesure:

x=70°

e)

There is a rectanglar triangle with a angle of 64°

The complement is 90°-64°=26°

The inscribed angle of mesure x has a mesure which is the half of the center angle of 26°

So x=13°

Multiplies to -2 adds to 6

Answers

xy=-2
x+y=6

minnus x from second equation
y=6-x
sub for y
x(6-x)=-2
6x-x^2=-2
add x^2 both sides and minus 6x both sides
0=x^2-6x-2
use quadatic formula

if you have
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^(2)-4ac} }{2a}


x^2-6x-2=0
a=1
b=-6
c=-2
x=\frac{-(-6)+/- \sqrt{(-6)^(2)-4(1)(-2)} }{2(1)}
x=(6+/- √(36+8) )/(2)
x=(6+/- √(44) )/(2)
x=(6+/- 2√(11) )/(2)
x=3+/- √(11)

x=3+ √(11) or x=3- √(11)
aprox
x=6.31662 or -0.316625

those are the numbers

6.31662 and -0.316625
