1/4 because there are 8 letters in vacation and two a’s meaning it’s a 2/8 chance simplify that to 1/4 (25%)
given,
height of triangle(h)=3.5 in.
base of triangle (b)=4 in.
length of side of triangle(s)= 4 in.
length of prism(l)=9 in.
we have,
surface area of traingular prism( A)=bh+2ls+lb
=4×3.5+2×9×4+9×4
=14+72+36
=122 square inches

Answer:
The image will be congruent to the pre-image because n=1
Step-by-step explanation:
The image dimensions are the original dimensions multiplied by the scale factor. If the scale factor is 1, the image is the same size as the original, hence congruent to the pre-image.

Answer: 9/38</h3>
Reason:
There are 10 red cards out of 10+10 = 20 total.
10/20 = 1/2 is the probability of selecting a red card.
If the red card is not put back (i.e. "no replacement"), then the chances of getting another red card is (10-1)/(20-1) = 9/19
Multiply the two fractions mentioned to get the final answer.
(1/2)*(9/19) = (1*9)/(2*19) = 9/38
I believe the answer is 0.022
