Answer:
Each side of the square in centimetres = 10.80 centimetres
Step-by-step explanation:
To convert from one unit to another or in between units we make use of conversion factors or conversion formulas
The conversion factor for the conversion of units in centimetres to units in inches is given as about 2.54 centimetres being equivalent to 1 inch
Therefore;
1 inch = 2.54 centimetres
4.25 inches = 2.54 × 4.25 = 10.795 ≈ 10.80 centimetres
Therefore, each side of the square in centimetres = 10.80 centimetres.
Answer:4
Step-by-step explanation:
Answer:
-5x-3y^3
Step-by-step explanation:
x-3y^3+3x^3-5x-x^3-x-2x^3
Part A:
The given values in form of ordered pairs are:
(2,1), (3,1), (4,-3), (3,-3)
A relation can be a function if one value of x is paired with exactly one value of y. In this case, x value of 3 is paired with two y values 1 and -3. So this relation is not a function.
Part B:
f(h) = 15h + 5
f(8) can be found by substituting h=8 in above equation.
So,
f(8) = 15(8) + 5 = 125
h represents the number of hours and f(h) represents the earnings of Kylie. So f(8) shows that Kylie earned $125 from 8 hours of work in the cafe
Part C:
For r hours of work, we can write:
f(r) = 15r + 5
So, the ordered pair can represent this relation as:
(r, f(r))
or
(r, 15r+5)
Answer:
10
Step-by-step explanation:
Given:it takes them 1.5 hours to plant one acre.
So, in order to plant all 15 acres it would take
15/1.5 = 10 hours
