Answer:
12-157.5 13-6ft
Step-by-step explanation:
the first one just look up 65% of 450 and minus the number you get by 450
the second one do the butterfly method
the heights on top and shadows on bottom
12x=72
x=6
PLEASE HELP! Triangle A’B’C’ is a dilation of triangle ABC.
2 answers:
Answer: 0.5
Step-by-step explanation:
We know that the scale factor for dilation is the ratio of the side-length of the image to the side-length of the pre-image.
From the given figure, In Pre-image ΔABC , we have AC=18
In Pre-image ΔA'B'C', we have A'C'=9
Now, the scale factor will be :_
Now, the scale factor for this dilation = 0.5

Answer:
35.9 grams
Step-by-step explanation:
We use the formula:
Where
q is heat released
m is mass
C_p is the constant 2.44
ΔT is change in temperature
We put the info in the formula and solve for m (mass):
The mass of ethanol is 35.9 grams
notice... the dog's pen perimeter, does not include the side that's bordering the garden's, since that side will use the heavy duty fence, instead of the light one
so, the sum of both of those costs, will be the C(x)
so, just take the derivative of it, and set it to 0 to find the extremas, and do a first-derivative test for any minimum
