★ ∆ ABC is similar to ∆DEF
★ Area of triangle ABC = 64cm²
★ Area of triangle DEF = 121cm²
★ Side EF = 15.4 cm
★ Side BC
Since, ∆ ABC is similar to ∆DEF
[ Whenever two traingles are similar, the ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides. ]
❍ <u>Putting the</u><u> values</u>, [Given by the question]
• Area of triangle ABC = 64cm²
• Area of triangle DEF = 121cm²
• Side EF = 15.4 cm
❍ <u>By solving we get,</u>
<u>Hence, BC = 11.2 cm.</u>

Answer:
Option C
Step-by-step explanation:
Given
Total length of ribbon lucy has=4 inches
She wants to divide it into 6 equal sized pieces so
Length of each piece=4/6
This can also be written as:
Length of each piece=4*(1/6
)
Now we will look at the options one by one:
For A, Each piece has 6/4 inches of ribbon.. This statement is not true as we have to divide 4 inches into 6 pieces so 4 is supposed to be in the numerator.
For B, breaking down 4/6 gives us 4*(1/6), so the statement is not true.
For C , as we can see that the expression is 4*(1/6), each piece will have 1/6 of inches of ribbon.
So option C is the correct answer..

Answer:
No, A″C″B″ is located at A″(1, 1), C″(4, 3), and B″(1, 5)
Step-by-step explanation:
Line AB is horizontal, so reflection across the x-axis maps it to a horizontal line. Then rotation CCW by 90° maps it to a vertical line. The composition of transformations cannot map the figure to itself.
A reasonable explanation is the last one:
No, A″C″B″ is located at A″(1, 1), C″(4, 3), and B″(1, 5)
61 is the prime number.
39 is divisible by 3 and 13.
27 is divisible by 9 and 3.
76 is divisible by several numbers, including 2.
