Answer:
CD = √11 and CE = √11
Step-by-step explanation:
We know that m∠D is 45° (by using the sum of interior angles in a triangle) so therefore, ΔDCE is a 45 - 45 - 90 triangle (the 45, 45, and 90 refer to the angle measures). The ratio of sides in a 45 - 45 - 90 triangle is 1 : 1 : √2 where the 1s are the sides and the √2 is the hypotenuse. We need to solve for x in x : x : √22. If you notice that √22 = √2 * √11, we can use this to find x, therefore, x = 1 * √11 = √11 so CD = √11 and CE = √11.
they are giving you the answer AB=AC, so what that means is that the angles are congruent to each other so if angle AC=15 and angle DC=5 all the angles will be the same.
We are given with the following:
Effective annual interest, i = 0.0425
Future worth, F = $25000
Number of years, n = 18
We use the formula to solve for the present worth of the money:
P = F / (1 + i)^n
P = 25000 / (1 + 0.0425)^18
P = 11818.73

Answer:
5, 0.55, 2.00, 3 cm.
Step-by-step explanation:
If you're asking about the unit rates, then..
a. For 1 day, there is 5 mm of rain. 15 / 3 = 5
b. One chocolate bar costs $0.55. 2.20 / 4 = $0.55
c. $14.00 / 7 = 2.00 Indu saves $2.00 for one day.
d. 12 / 4 = 3 cm. For one month, philip grew 3 cm.
I hope this helped :)
