Lera25 [3.4K]
 Simple Interest Formula: A = P(1 + rt)

1555 = 1000(1+(0.05*t))

1.55 = 1 + (0.05*t)

0.55 = 0.05t

11 = t

The answer is 11. Whether that is 11 years or months or whatever depends on your exact question.

Triangle ABC is rotated 100° counterclockwise about point P to create ΔA′B′C′. What is m∠C′A′B′
gizmo_the_mogwai [7]

Answer:

Angle CAB

Step-by-step explanation:

Given that a triangle ABC is rotated 100 degrees counterclockwise about a point P. New triangle formed is Triangle A'B'C'.

A rotation is a transformation in which the object is rotated about a fixed point. The direction of rotation can be clockwise or anticlockwise. The fixed point in which the rotation takes place is called the center of rotation.

Here fixed point is P and angle is 100 degrees

The property of rotation is rotation is a transformation of transforming a geometric figure to a similar figure.

In other words, by rotation here ABC will be similar to A'B'C'

Hence angles of ABC will remain equal to angles of A'B'C' in that order.

So m/_ C'A'B'=m /_CAB

Answer:

31.5

Step-by-step explanation:

Assuming that the lowest point and the highest point on the Ferris wheel are opposite each other, the difference of height will be the distance between the two points, and thus, the distance across fo the Ferris wheel. Divide this value by (2) to find the radius of the strucutre.

75 - 12

= 63

63 / 2

= 31.5
