Answer:
The answer should be "B" (The area of △RST is equal to the area of △LMN.)
To answer this you need to find the LCD (least common denominator) 2/3times4=8/12 and 3/4times3=9/12 and 9+8=17 then 17-12=5 so she bought 1 5/12 yards of ribbon
Answer:
12
Step-by-step explanation:
43 + 29 = 72
? = 72 - 60 = 12
therefore, 43 + 29 = 12 + 60
10 × 2 tens = 20 tens = 200
Answer:
=14.69km²
Step-by-step explanation:
We can use the Hero's formula to calculate the area
A= √(s(s-a)(s-b)(s-c))
s is obtained by adding the lengths of the three sides of the triangle and then dividing by 2, a, b and c are the ides of the triangle.
S=(5+6+7)/2
=9
A=√(9(9-6)(9-5)(9-7))
=√(9×3×4×2)
=√216
=14.69km²
