Kaylani is going to make a blanket by sewing a 4-foot long piece of ribbon along the diagonal of a piece of rectangular fabric. She wants the length of the blanket to be 18 inches longer than the width. What is the approximate perimeter of the blanket? Round to the nearest inch.
Answer:
As the largest side is
15
yards and smaller sides are
9
yards and
12
yards
from Pythagoras theorem, if the triangle is right angled square of largest side should be equal to sum of the squares of smaller two sides.
Square of largest side is
15
2
=
225
and squares of smaller two sides are
9
2
=
81
and
12
2
=
144
.
As
225
=
81
+
144
, the triangle is right angled.

Answer:
since 3x^2-7x+4=0 is in the form ax^2+bx+c=0, a=3, b=-7, c=4
Answer:
7 - - 5 = 12
Step-by-step explanation:
Answer:
16%
percentage is calculated by 100
A. 2500 × 1/100 = 25%
B. 4100 x 1/100 = 41%
41% - 25%
16%
therefore bridge A is 16% shorter than bridge B
