Step-by-step explanation:

4*-2 + 3*-3 = -8 - 9= -17

4*1 +3*-2= 4-6= -2

-2*-2 + 3*-3= 4-9= -5

-2*1 + 3*-2= -2 -6 = -8

-4*-2+6*-3=8-18= -10

-4*1+6*-2=-4-12= -16

the result matrix is

-17 -2

-5 -8

-10 -16

When you have a scale factor as percentage, is better to convert that percentage into a fraction by divide it by 100%. That way, it will be much easier to scale your figures.

1. The scale factor we need to apply to our rectangle is 60%. Firts, lets convert our scale factor into a fraction: $\frac{60}{100} = \frac{3}{5}$ . Next, we just need to multiply each side of our rectangle by our fraction:
length= $16( \frac{3}{5})=9.6$
width= $8( \frac{3}{5} )=4.8$
So, our new rectangle will have a length of 9.6 units and a width of 4.8 units.

2. This time the scale factor is 120%. Just as before, lets convert it into a fraction: $\frac{120}{100} = \frac{6}{5}$ , and just as before lets multiply each side of our triangle by our fraction:
base= $10( \frac{6}{5} )=12$
side= $8( \frac{6}{5} )=9.6$
So, our new isosceles triangle will have a base of 12 units and tow sides of length 9.6 units each.

3. This time the scale factor is 150%. Just as before, lets convert it into a fraction: $\frac{150}{100} = \frac{3}{2}$ , and just as before lets multiply each side of our polygon by our fraction:
$12( \frac{3}{2} )=18$
$15( \frac{3}{2} )=22.5$
$13( \frac{3}{2} )=19.5$
So, our new polygon will have a side of 12 length units, tow sides of 15 length units, and two side of 15 length units.

4. This time our factor is 75%. Just as before, lets convert it into a fraction: $\frac{75}{100} = \frac{3}{4}$ , and just as before lets multiply each side of our parallelogram by our fraction:
side= $25( \frac{3}{4} )=18.75$
So, our new parallelogram will have tow sides of length 18.75 units.

Please help me<br><br> b minus 3/4 = 7/10

RoseWind [281]

B - 3/4 = 7/10
add 3/4 to both sides to isolate the b
b = 7/10 + 3/4
b = 28/40 + 30/40
b = 58/40
b = 1 18/40
b = 1 9/20

a cd usally sells for 17.00 if the CD is 30% off and the sales tax is 8% what is the total price of the CD including tax

Ksenya-84 [330]

Answer:

$12.85

Step-by-step explanation:

First we need to find the sale price of the CD

Sale price = old price - old price * discount rate

= 17 - 17* .3

= 17 - 5.1

= 11.9

The sale price of the CD is 11.90

Now we need to find the tax

tax = sale price of cd * tax rate

= 11.9 * .08

= .95

The final cost of the CD is sale price of CD plus the tax

Total cost = sale price of CD + tax

= 11.90 + .95

=12.85
