Recall that the formula for the perimeter of a rectangle is: 2Length+2Width
With this in mind, we have that the original design is 96×60, where 90 is length and 60 is width, so it would simply be:
2(96+l) + 2 (60+w) = New Perimeter
Or simplified, it'd be:
2l + 2w + 312 = New Perimeter
lets say there are 100 girls.
4/5 of 100 is 80, so 80 girls have brown hair.
3/4 of the 80 who have brown hair have long hair.
3/4 of 80 is 60.
so we know that out of 100, 60 have long brown hair.
in simplest fraction form, 60/100= 3/5
Answer:
true
Step-by-step explanation:
4+3+9=3+4+9
use the commutative property to rearrange the terms.
4+3+9=4+3+9
equality is true because both members are identical.
Answer:
62.79cm
Step-by-step explanation:
<u>We are using TRIGONOMETRY</u>. To find the area of a triangle with 2 lengths and a non-right angle, we will use the sine rule.
Area of Triangle = 1/2 * a * b * sin(c)
(Where a & b represent our lengths, and sin(c) represents our angle.)
Area of Triangle = 1/2 * 10 * 13 * sin(105)
Area of the Triangle = 62.79cm
