Answer:
The scale factor James used to go from Rectangle N to Rectangle P is 3 or 3:1
Step-by-step explanation:
Given that Rectangle N has an area of 5 square units. That is An = 5
Rectangle P has an area of 45 square units. That is Ap = 45
The scale factor James used to go from Rectangle N to Rectangle P will be in the form
An/Ap = N^2/P^2
Where N and P are the factors
(N/P)^2 = 5/45
N/P = sqrt root (1/9)
N/P = 1/3
Cross multiply
P = 3N
The scale factor James used to go from Rectangle N to Rectangle P is therefore equal to 3 or 3:1
Remember, you can do anything to an equation as long as you do it to both sides
and for inequalities, if you multiply or divide both sides by a negative, you have to flip the direction of the inequality sign
so
-6y+3>9-7y
add 7y to both sides
y+3>9
minus 3 both sides
y>6
Answer:
Yes
Step-by-step explanation:
The line is good because it is representing the data accuratly because it is in the middle of all the data points and since all the point are near the line, it is accurate.
Answer: 90 minutes
Step-by-step explanation:
Area of the side = 15 x 18 = 270 sq. ft.
3 sq. ft take a minute to paint
270 sq. ft. will take 270 / 3
= 90 minutes
