Answer:
30 to 50 more feet
Step-by-step explanation:
Add up all the sides to find the perimeter of the shape for the pen:
18 + 22.5 + 5 + 4.5 = 50
Since 50 is less than 80 to 100, then Annie has 30 to 50 more feet she can use for the pen.
17.4.....add all the numbers and divide by 10
Answer:
70√2 units²
Step-by-step explanation:
(see attached for reference notes on parallelograms)
we are given ABCD is a parallelogram where
Short Length, AB = 10 units
Long Length, BC = 14 units
Angle A = 45°
The area of the parallelogram is hence,
= AB x BC sin 45°
= 10 x 14 x sin 45
= 140 sin 45° (recall from special angles, that sin 45° = 1/√2)
= 140/√2 (remove radical from denominator by multiplying by √2/√2)
= (140/√2) x (√2/√2)
=70√2 units²
Take 12500-11625, which is 875.
Divide 875 by the original price, 12500, to get 0.07.
Multiply 0.07 by 100.
Your answer should be a 7% reduction.
