Considering the area of the right triangle, it is found that Salome used a scale factor of 1/2 to go from triangle R to triangle T.
<h3>What is the area of a right triangle?</h3>
The area of a right triangle is given by half the multiplication of the lengths of it's sides.
In this figure, we have that the sides have lengths of 4 and 5 units, hence the area is given by:
A = 0.5 x 4 x 5 = 10 square units.
The area is one fourth of the area of triangle R. Since we are dealing with an area, that works in squared units, the scale factor is given by:
S = sqrt(1/4) = 1/2.
Hence Salome used a scale factor of 1/2 to go from triangle R to triangle T.

Answer:
x=-5 or x=3
Step-by-step explanation:
when multiplying anything by 0, the answer will be zero
In this case, one of the two factors has to be equal to 0
start by splitting into
(x+5) = 0
solve the equation
subtract 5 from both sides
x = -5
now, repeat for the other binomial
x-3 = 0
add 3 to both sides
x=3
The linear speed of one of the cars is 7.75 feet per second
The cars (seats) of a Ferris wheel are positioned 74 feet from its center.
The radius, r = 74 feet
The Ferris wheel makes 4 revolutions every 4 minutes
Number of revolutions per minute = 1
Angular speed, w = 1 rev/min
Angular speed, w = 0.10472 rad/sec
The relationship between the linear speed (v), and the angular speed (w) is:
v = wr
Substitute w = 0.10472 and r = 74 feet into the formula:
v = 0.10472 x 74
v = 7.75 feet per second
The linear speed of one of the cars is 7.75 feet per second
