Answer:
The length side of the pre-image is 16 units
Step-by-step explanation:
we know that
The length side of the image is equal to the length side of the pre-image multiplied by the scale factor
or
The length side of the pre-image is equal to the length side of the image divided by the scale factor
in this problem we have that
The scale factor is 1/2
The length side of the image is 8 units
therefore
8/(1/2)=16 units
The length side of the pre-image is 16 units
17.01+5+2+3= 27.01 (total expense)
100-27.01= 72.99 (change)
5+2= 7 (total winnings)
72.99+7.00= 79.99 (total change).
The answer is: [D]: "42" .

Consider the "1/9" to be close to "1/10" ; (that is; "0.1" ; since "0.1 = 1/10" ) .
Note that a "negative value" multiplied by a "negative value" equals a "positive value".
Round the "14.1" to "14" ; and the "2.9" to "3" ;
_______________________________________
-14.1 * -2.9 ≈ 14* 3 = 42 .

Answer:
yes
Step-by-step explanation:
First we should find a GCF for the number of boys and girls.
The gcf for the two would be 4.
Divide.
20/4 = 5
28/4= 7
therefore the ratio for boys to girls would be 5 to 7
