Answer:
19 years
Step-by-step explanation:
Initial height of tree when Samiya bought the tree = 3 inches
Growth in the height of tree every year = 5 inches
Number of years = 
Growth in the height of tree in years = 5 inches multiplied by number of years
Growth in the height of tree in years = 5 inches
To find:
Number of years taken by the tree to be 8 ft or 96 inches.
Solution:
The equation for height of tree after years can be written as:
3 + 5 which is to be compared with 96 inches.
Therefore, the equation is:
Therefore, it will take <em>19 years</em> for the tree to reach a height of 96 inches.
Answer:
31/100
Step-by-step explanation:
0.310=0.31
Since the number ends in the hundredths place as a fraction it would be 31/100
Hope this helps! :)
Answer:
Sure Amaya , the grouping is the parenthesis, right?
Step-by-step explanation:
so just add up.. the things outside of the parenthesis
- 
* 4
so exponents come first in the order of what to do... right?
=16 okay , got that part, the next part is
16 * 4 = 64 okay got that part, now
- 64 is what is subtracted from the grouping , got it?
Answer:
The polygon has 43 sides . The polygon can be called 43 - gon or tetracontakaitrigon.
Step-by-step explanation:
In a regular polygon all the sides are equal and also all the angles are equal. The sum of the interior angle of a polygon can be calculated with the following formula;
sum of interior angle = (n−2) × 180°
where
n = number of sides
The sum of the interior angle should be less than 7500 and greater than 7201.
sum of interior angle = (n−2) × 180°
less than 7500 and greater than 7201 = (43 - 2) × 180
less than 7500 and greater than 7201 = 41 × 180
less than 7500 and greater than 7201 = 7380
°
The polygon has 43 sides . The polygon can be called 43 - gon or tetracontakaitrigon.
Answer:
<em>2 solutions</em>
Step-by-step explanation:
Given the expression
2m/2m+3 - 2m/2m-3 = 1
Find the LCM of the expression at the left hand side:
2m(2m-3)-2m(2m+3)/(2m+3)(2m-3) = 1
open the bracket
4m²-6m-4m²-6m/(4m²-9) = 1
Cross multiply
4m²-6m-4m²-6m = 4m² - 9
-12m = 4m² - 9
4m² - 9+12m = 0
4m² +12m-9 = 0
<em>Since the resulting equation is a quadratic equation, it will have 2 solutions since the degree of the equation is 2</em>
