Tell whether the rates are equivalent. Justify your answer.
60 centimeters every 2.5 years
30 centimeters every 15 months10
Answers
Answer:
30 centimeters every 15 months is correct the other one isnt.
Step-by-step explanation:
The rates are equivalent, and we can justify this by converting the time units to make a valid comparison.
To determine if the rates are equivalent, we need to compare the ratios of centimeters to time between the two rates.
Rate 1: 60 centimeters every 2.5 years
Rate 2: 30 centimeters every 15 months
Let's convert both rates to a common time unit to make a valid comparison. We can convert years to months or months to years.
Converting Rate 1:
2.5 years * 12 months/year = 30 months
Rate 1 becomes 60 centimeters every 30 months.
Now, let's compare the rates:
Rate 1: 60 centimeters every 30 months
Rate 2: 30 centimeters every 15 months
The rates are equivalent because the ratios of centimeters to time are the same for both rates. In both cases, the ratio is 2 centimeters per month.
Therefore, the rates are equivalent, and we can justify this by converting the time units to make a valid comparison.

Suppose m is the line with equation y = −4 and ΔA'B'C is mapped to ΔA"B"C" by applying the glide reflection T⟨3, 0⟩ ∘ Rm. What are the coordinates of ΔA″B″C″?
Answers
Answer:
[tex]A" = (-1,-3)[/tex] [tex]B" = (-2,-6)[/tex] [tex]C" = (1,-7)[/tex]
Step-by-step explanation:
Given
See attachment for graph
[tex]A' = (-4, -5)[/tex]
[tex]B'=(-5, -2)[/tex]
[tex]C' = (-2, -1)[/tex]
First, reflect over [tex]y =-4[/tex]
The rule is: [tex](x,y) ==> (x,y+h)[/tex]
Where [tex]h =-4[/tex]
So:
[tex]A' = (-4, -5)[/tex] [tex]==>[/tex] [tex]A'' = (-4, 1-4) = (-4, -3)\\[/tex]
[tex]B'=(-5, -2)[/tex] [tex]==>[/tex] [tex]B'' = (-5, -2-4) = (-5, -6)[/tex]
[tex]C' = (-2, -1)[/tex] [tex]==>[/tex] [tex]C'' = (-2, -3-4) = (-2, -7)[/tex]
So, we have:
[tex]A" = (-4,-3)[/tex] [tex]B" = (-5,-6)[/tex] [tex]C" = (-2,-7)[/tex]
Next translate A''B''C'' by T(3, 0), we have;
The rule is: [tex](x,y)==>(x+3,y+0)[/tex]
[tex]A" = (-4,-3)[/tex] [tex]==>[/tex] [tex]A" = (-4 + 3, -3+0) = (-1, -3)[/tex]
[tex]B" = (-5,-6)[/tex] [tex]==>[/tex] [tex]B" = (-5 + 3, -6) = (-2, -6)[/tex]
[tex]C" = (-2,-7)[/tex] [tex]==>[/tex] [tex]C" = (-2 + 3, -7) = (1 , -7)[/tex]
Hence, A''B''C'' are:
[tex]A" = (-1,-3)[/tex] [tex]B" = (-2,-6)[/tex] [tex]C" = (1,-7)[/tex]

There are 19 5s in 95.
Now we multiply 19 by 3 to find out how many feet it represents.

-6|4p+2|+8 > -34
Answers
Answer
p>5/4 or p<-9/4
Step-by-step explanation:
1. first isolate the absolute value by subtracting 8 and then dividing by -6
2. you then split the absolute value inequality into 4p+2>7 and 4p+2<-7
3. When you solve those, you get p>5/4 and p< -9/4
Answer:
[tex] - \frac{9}{4} < p < \frac{5}{4} [/tex]
Step-by-step explanation:
1) Subtract 8 from both sides.
[tex] - 6 |4p + 2| > - 34 -8[/tex]
2) Simplify -34 - 8 to -42.
[tex] - 6 |4p + 2| > - 42[/tex]
3) Divide both sides by -6.
[tex] |4p + 2| < \frac{ - 42}{ - 6} [/tex]
4) Two negative numbers makes a positive.
[tex] |4p + 2| < \frac{42}{6} [/tex]
5) Simplify 42/6 to 7.
[tex] |4p + 2| < 7[/tex]
6) Rewrite the inequality without the absolute value.
[tex] - 7 < 4p + 2 < 7[/tex]
7) Subtract 2 from the whole equation.
[tex] - 7 - 2 < 4p < 7 - 2[/tex]
8) Simplify.
[tex] - 9 < 4p < 5[/tex]
9) Divide the whole equation by 4.
[tex] - \frac{9}{4} < p < \frac{5}{4} [/tex]
Therefor, the answer is - 9/4 < p < 5/4.

In the year 2006, a person bought a new car for $24000. For each consecutive year after that, the value of the car depreciated by 10%. How much would the car be worth in the year 2010, to the nearest hundred dollars?
Answers
Answer:
$15,746.400
Step-by-step explanation:
The computation of the car value in the year 2010 is shown below:
Since the new car brought in the year of 2006 at $24,000
And, it would be depreciation by 10%
So, in the year 2010 the car value would be
= $24,000 × (1 - 0.10)^4
= $24,000 × 0.9^4
= $15,746.400
