The answer is 30. you can find the unit rate but the calculator was invented a long time ago so i used that ;)
Answer:
(a) AD=6 cm
(b) 66 cm²
(c) 38 cm
Step-by-step explanation:
(a) To get the length of AD, we can use pythagoras on the triangle part. Let's say the dotted line intersects DC at E. Then since AB and DC are parallel, AD is equal to BE. EC = 8 cm simply by subtracting AB from DC (15-7=8).
Then pythagoras says that 8²+BC²=10². So BC = √(100-64) = 6. And since BC=AD, AD is also 6.
(b) Area of the rectangle DEBA is 7*6 = 42. Area of triangle ECB is base times half height: 8*3 = 24. Sum is 42+24 = 66 cm²
(c) Perimeter is 7+10+15+6 = 38 cm. Add all the side lengths.

8 inches
Divide 56 by 7 which equals 8 so Fred's frog jumped 8 inches.
Step-by-step explanation:
Total money paid=$110+$5.5=115.5
Cost of each shirt=$8
Therefore,
No. of T shirt req.=115.5/8=14.4
So they req. 15 T-Shirts
