<em>Final Answer: </em>
The answer is A although the sales tax is uniform , since the Corbins made less money so they paid more sales tax from their pocket thats what regressive tax is about.<span />
Step-by-step explanation:
for such regular figures the volume is always
ground area × height.
the volume of the green box (bar on a rectangle) at the bottom is therefore
16×7×3 = 336 in³
the volume of the red object on top (based on a right-angled triangle) we get
5×3/2 × 6 = 5×3×3 = 45 in³
so, the total volume is the sum of both sub-volumes :
336 + 45 = 381 in³
Answer:
It will take 4 minutes and 30 seconds for hot coffee to cool to a temperature of 25 ° C
Step-by-step explanation:
This problem can be modeled by a first order equation
T(t) = TA + kt
In which TA is the temperature at instant zero and r is the rate of warming(g>0) or cooling(k<0). t is the time in minutes.
The initial temperature of the cup of coffee is 70ºC. So TA = 70. The temperature cools at the rate of 10ºC per minute, so k = -10. So, the equation of the model is:
T(t) = 70 - 10t
We want to know the instant of time when T = 25, so:
25 = 70 - 10t
10t = 70 - 25
10t = 45
t = 4.5 minutes
It will take 4 minutes and 30 seconds for hot coffee to cool to a temperature of 25 ° C
<span> Answer: 1 One way to determine the greatest common factor is to find all the factors of the numbers and compare them.
The factors of 26 are 1, 2, 13, and 26.
The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.
The factors of 75 are 1, 3, 5, 15, 25, and 75.
The only common factor is 1. Therefore, the greatest common factor is 1</span>
<span>
The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.
The prime factors of 26 are 2 and 13.
The prime factors of 48 are 2, 2, 2, 2, and 3.
The prime factors of 75 are 3, 5, and 5.
The are no prime factors in common, so the greatest common factor is 1.
Another way to approach this is to look at the differences between the numbers. The difference between 26 and 48 is 22. The difference between 48 and 75 is 27. The greatest common factor of two or more numbers cannot be larger than the smallest difference between the numbers. The greatest common factor of 26, 48, and 75 must also be a factor of the differences between the numbers. So, the greatest common factor of 22 and 27 is also the greatest common factor of 26, 48, and 75. The greatest common factor of 22 and 27 is 1, so the greatest common factor of 26, 48, and 75 is also 1.
