Step-by-step explanation:
Matea recorded that water levels in one part of the river fell 1.05 millimeters per year for 2.48 years. Describe how you could estimate the total variation in water level.
NO SAMPLE RESPONSES FROM ED PLEASE
Answer:
The total variation in water level is -3.3
Step-by-step explanation:
Round 1.05 mm to the nearest whole number the result is -1.1 then round 2.48 which the result will be equal to 3. The total variation in water level is -3.3
The total variation in water level is -2.6.
We have,
Matea recorded that water levels in one part of the river fell 1.05 millimeters per year for 2.48 years.
The decrease of the rate -1.05 mm/year can be rounded to -1.
Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.
Thus, the total variation in water level is -2.6.

Name a combination of coins that is 130% of the value of a dollar.
Answer:
5 quarters, 1 nickel
Step-by-step explanation:
A combination of coins which is equivalent to 130% of a dollar is equal to 8 quarters,2 dimes and 2 nickels.
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given: A dollar and to find its 130% equivalent in the form of coins.
A nickel is worth 5 cents
A dime is worth 10 cents
A quarter is worth 25 cents
Now a dollar is equivalent to 100 cents
Thus 130% of a dollar is equivalent to
130/100 ×100 +100 =230 cents
Therefore a combination of 8 quarters which is equal to 200 cents and 2 dimes and 2 nickel is equal to 230 cents as
8×25+2×10+2×5=230 cents.
Hence, A combination of coins which is equivalent to 130% of a dollar is equal to 8 quarters,2 dimes and 2 nickels.

On Monday, Jill used 12 quart of paint in 34 hour. On Tuesday, Jill was distracted by texting and used 12 quart of paint in 54 hour. What is the difference in her usage rates in quarts per hour?
A)1/4
B)2/3
C)4/15
D)16/15
Answer:
C
Step-by-step explanation:
The difference in her usage rates in quarts per hour is 4/15, the correct option is C
What is the average rate of change?The average Rate of Change of the function f(x) can be calculated as;
[tex]f(x) = \dfrac{f(b) - f(a)}{b-a}[/tex]
Given;
Jill used 12 quart of paint in 34 hour
Jill was distracted by texting and used 12 quart of paint in 54 hour
Now,
1/2 per 3/4 hour = (4/3)(1/2) = 2/3 per hour
1/2 per 5/4 hour = (4/5)(1/2) = 2/5 per hour
2/3 - 2/5 = 10/15 - 6/15 = 4/15
Therefore, the rate difference will be 4/15
