Answer:

3/4 of a foot will cost $2.25.

Step-by-step explanation:

This question is solved by rule of three, due to proportions.

One foot of lace costs 3 dollars. How much is 3/4 of a foot going to cost?

1 foot - 3 dollars

3/4 foot - x dollars

$x = 3 \times \frac{3}{4} = \frac{9}{4} = 2.25$

Answer:

38.7

Step-by-step explanation:

$\frac{sinA}{A}=\frac{sinB}{B}=\frac{sinC}{C}$

A, B and C are the sides of the triangle and sinA, sinB and sinC are the opposing angles

$\frac{sin95}{43}=\frac{A}{27}$

$A = sin^{-1} (\frac{27*sin95}{43} )=38.72018809$

alexira [117]

Answer:(6,-2)

Step-by-step explanation:

M is the midpoint of AB then ,

M = $\frac{A+B}{2}$

$5=\frac{x+4}{2}$ , $-2=\frac{y-2}{2}$

$10=x+4$ , $-4=y-2$

$x=6$ , $y= -2$

so, B= (6,-2)
