80 POINTS MATHIn the diagram at the right, in which position are the tips of the scissors farther apart? Explain your reasoning..

Answers

hey mate..

the position at which the tips of the scissors will be FARTHER APART is at position B.

as the angle made by the scissors at the centre is greater in position B.

Answer:

the degree angle of scissor B is greater as its angle number is greater than A

32 is a greater number than 26 therefore the degree of angle 32 is wider than the degree of 26

Adrian shops for school clothes and spends a total of $93.42. If the local tax rate is 8%, how much was the cost without taxes?

Answers

Based on the amount that Adrian spent in total, the cost without taxes was $86.50.

The cost of the clothes was $93.42 including tax.

Assuming the original cost is x, the equation is:

Total cost = Original cost x ( 1 + tax)

Solving would give:

93.42 = x × (1 + 8%)

93.42 = 1.08x

x = 93.42 / 1.08

= $86.50

In conclusion, the cost without taxes was $86.50.

Answer:

85.95

Step-by-step explanation:

If the local tax was 8% and we want to know what is was without the tax then we need to do 93.42 times .92

$93.42*.92=85.9464$

Since money only goes to the hundredths place we need to round there

$85.95$

Answer:

$x=6\ny=-8$

Step-by-step explanation:

$(1)/(3)x-(1)/(8)y=3\n 7y+9x=-2$

One method could be rewriting the second equation as x in terms of y and solving by replacing in the first equation.

$7y+9x=-2\n9x=-2-7y\nx=(-7y-2)/(9)$

Replace...

$(1)/(3)x-(1)/(8)y=3$

$(1)/(3)((-7y-2)/(9))-(1)/(8)y=3$

$(-7y-2)/(27)-(1)/(8)y=3$

$-(7)/(27)y-(2)/(27)-(1)/(8)y=3$

add $(2)/(27)$ on both sides.

$-(7)/(27)y-(1)/(8)y=3+(2)/(27)$

Combine like terms

$((-7)(8)-(1)(27))/((27)(8)) y=((3)(27)+2)/(27)$

$(-56-27)/(216) y=(81+2)/(27)$

$(-83)/(216)y =(83)/(27)$

Now, to get rid of the fraction and isolate y, multiply by the reciprocal or the inverted fraction.

$((216)/(-83)) (-83)/(216)y =(83)/(27)((216)/(-83))$

$y=(216)/(-27)$

Simplify

$y=-8$

Now replace the value of y in either equation to find x.

$7y+9x=-2\n7(-8)+9x=-2\n-56+9x=-2$

add 56

$56-56+9x=-2+56\n9x=54\n$

Divide by 9

$(9x)/(9)=(54)/(9)\n x=6$

To check whether these values are accurate, replace in either equation both values and you should have an equality. In this case I'll do it in both equations.

$(1)/(3)x-(1)/(8)y=3$

$(1)/(3)(6)-(1)/(8)(-8)=3$

$2-(-1)=3\n2+1=3\n3=3$

-----------------------------------------------------------------

$7y+9x=-2\n7(-8)+9(6)=-2\n-56+54=-2\n-2=-2$
