HELP ME PLS I NEED TO FIGURE OUT 8/15 TIMES -3/10!!!!! PLS TELL ME

2 answers:

8 0

The answer is: " - 4/25 " ; or, write as: " - 0.16 " .
___________________________________________________
Explanation:
___________________________________________________
Method 1):
_______________________________________________________
8/15 * -3/10 ; the (-3) cancels to "-1" and the "15" cancels to "5" ;
{"Since: (15÷3=5} ; and since: (-3÷3= -1} ;

the "8" cancels to a "4" ; and the "10" cancels to a "2" ;
{"Since: (8÷2=4) ; and since: {10÷2 =5} ;

And we can rewrite the problem as:
4/5 * -1/5 ;
_______________________________________________________
→ 4/5 * -1/5 = (4*-1) / (5*5) ;

= - 4/25 ;
{or, write as: "-0.16 " }.
_________________________________________________________
Method 2)
_________________________________________________________
8/15 * -3/10 = (8*-3) / (15*10) '

= -24/150 = ? ;

Divide each side of this "fraction" by: "6" ;

(-24÷6) / (150÷6) = " - 4/25 "; or, write as: " - 0.16" .

Given the preimage and image,find the dilation scale factor.

Oliga [24]

Answer:

The dilation scale factor is $\frac{1}{2}$ .

Step-by-step explanation:

The image is the dilated form of its preimage if and only if the following conditions are observed:

1) $K' = \alpha_{1} \cdot K$

2) $T' = \alpha_{2} \cdot T$

3) $P' = \alpha_{3} \cdot P$

4) $J' = \alpha_{4} \cdot J$

5) $\alpha_{1} = \alpha_{2} = \alpha_{3} = \alpha_{4}$

If we know that $K = (2, 0)$ , $K' = (1, 0)$ , $T = (3, 0)$ , $T' = (1.5,0)$ , $P = (1, 5)$ , $P' = (0.5, 2.5)$ , $J = (0, 3)$ and $J' = (0, 1.5)$ , then the coefficients are, respectively:

$\alpha_{1} = \frac{1}{2}$ , $\alpha_{2} = \frac{1}{2}$ , $\alpha_{3} = \frac{1}{2}$ , $\alpha_{4} = \frac{1}{2}$

As $\alpha_{1} = \alpha_{2} = \alpha_{3} = \alpha_{4}$ , we conclude that the dilation scale factor applied in the preimage is equal to $\frac{1}{2}$ .

Determine the value of x for which rls if<br> .<br> m2i = 80 - X; and<br> mz2 = 90 - 2x<br> .

Slav-nsk [51]

Answer:

x = 10

Step-by-step explanation:

For the lines to be parallel, the two angles must have the same measure:

80 - x = 90 - 2x

x = 10 . . . . . . . . . add 2x-80

The value of x must be 10 to make the lines parallel.
