Answer:
B, C, E are true
Step-by-step explanation:
A = l*w
The original rectangle is 6 by 4 with A = 24
The 1st enlargement = 6*3 by 4*3
18 by 12 with A = 216
The second enlargement is 18*3 by 12*3
54 by36 with A =1944
A.The area of the first enlargement is 72 square inches.
False it is 216
B.The area of the second enlargement is 1,944 square inches.
True
C.The area of the second enlargement is (3 squared) squared times the original area.
216/24 =9 True
D.The area of the second enlargement is 3 times the area of the first enlargement.
1944/24 = 9 False
E.The ratio of the area of the first enlargement to the area of the original equals the square of the scale factor.
The scale factor is 3 3^2 =9 216/24 =9
True
Answer: 176,995.52
Step-by-step explanation:
Pi equals 3.14, so 3.14 x 56,368 = 176,995.52
How To: Given a relationship between two quantities, determine whether the relationship is a function. Identify the input values. Identify the output values. If each input value leads to only one output value, classify the relationship as a function.
Answer:
x = 5
Step-by-step explanation:
Using similar triangles theorem
In similar triangles, ratio of their corresponding sides are equal.
Let the point where a line cuts BC = D
Length (AB/BD) = length(AC/CD)
15/3x = 9/(2x-1)
Cross multiply
15(2x-1) = 9(3x)
Expand the brackets
30x -15 = 27x
Collecting like terms
30x-27x = 15
3x = 15
Divide through by 3
x= 15/3
x= 5
