Answer:
90, 90, 90, 135, 135
Step-by-step explanation:
The sum of the measures of all angles is 540 deg.
The measures of the angles are: x - 45, x - 45, x, x, x - 45.
Add the expressions of the measures of the angles and set equal to the sum of the measures, 540 deg. Then solve for x. Then use the value of x to find each angle measure.
x + x + x - 45 + x - 45 + x - 45 = 540
5x - 135 = 540
5x = 675
x = 135
x - 45 = 135 - 45 = 90
Answer: 90, 90, 90, 135, 135

Answer:
The rate of change for the number of parakeets seen is 1/2
Step-by-step explanation:
The sightings can be approximated by the equation:
y = (1/2)*x + 3
Which represents a line. Any line can be writen by an equation in the following form:
y = m*x + b
Where m is the slope of the lane or it's rate of change and b is the value for "y" when "x" equals zero. Applying this knowledge to the equation of the bird sightings we can se that the sightings grows 1/2 for every one unit that x grows, therefore the rate of change is 1/2.
The percentage increase in team sales is 44% and this can be determined by using the unitary method.
Given :
The sales increase from 90 units to 130 units.
The following steps can be used in order to determine the percentage increase in sales:
Step 1 - The unitary method can be used in order to determine the percentage increase in sales.
Step 2 - According to the given data, the team sales are 90 units which are 100%. After increasing the sales becomes 130 units.
Step 3 - So, let the percentage of 130 units be 'x'. So, the value of 'x' is:
Step 4 - So, the percentage increase in sales is:
The percentage increase in team sales is 44%.
