Answer:
5.36
Step-by-step explanation:
Given that:
<BAD = <CAE, therefore, BD = EC
Let's take x to be the length of BD = EC
BD + DE + EC = BC
BC = 20,
BD = EC = x
DE ≈ 9.28
Thus,
x + 9.28 + x = 20
x + x + 9.28 = 20
2x + 9.28 = 20
Subtract 9.28 from both sides
2x + 9.28 - 9.28 = 20 - 9.28
2x = 10.72
Divided both sides by 2 to solve for x
BD ≈ 5.36
Answer:
3.5 ounces
Step-by-step explanation:
8.32 / 8 = 1.04
1 ounce is $1.04
3.64 / 1.04 = 3.5
#10
15(1/3y-3/5x-2/3y+4/15x)
Calculate
15(-y/3-x/3)
Write all numerator over common denominator
15(-y+x/3)
Multiply by reducing
-5(y+x)
Multiply parenthesis by -5
-5y-5x
#11
24(2/3y-3/4x-2/8y+5/6x)
Reduce fraction
24(2/3y-3/4x-1/4y+5/6x)
Calculate
24(5/12y+x/12)
Multiply parenthesis by 24
10y + 2x
2 1/3, absolute value is how far away that number is from 0
Area of a triangle = 1/2 x base x height
Area = 3.75 sq m
Base = 2.5 m
3.75 = 1/2 x 2.5 x height
3.75 x 2 = 2.5 x height
7.5/ 2.5 = height
height = 3 m
