54044.55 ÷ 100 = 540.4455
Answer:
Angle D is equal to 80.
Step-by-step explanation:
We know that the sides are congruent and that angle ACB is congruent to angle ECD by the vertical angles theorem.
Triangles' angles always add up to 180.
180 - 70 - 30 = 80
angle D is equal to 80.
Answer:
20
Step-by-step explanation:
To calculate the sum of the residuals, subtract the predicted sales from the actual sales in the table below.
Actual sales 55 150 325 510 780 990
Predicted sales 40 150 300 500 800 1,000
This will show the change between them. Add each residual to find the sum.
55 - 40 = 15
150 - 150 = 0
325 - 300 = 25
510 - 500 = 10
780 - 800 = -20
990 - 1000 = -10
These add up to be 15 + 25+ 10 +-20 +-10 = 20
Answer:
The Answer is: $2,200
Step-by-step explanation:
12% of 2500 is:
2500 × .12 = 300
Total new amount will be:
2500 - 300 = $2,200

Answer:
not enough information
Step-by-step explanation:
We know <E is congruent to <N.
We know the lengths of one pair of sides.
That is not enough information to prove that the triangles are similar.
