The answer would be 3 miles on each of the six days
Answer:
In a week we have 7 days.
On the first day, Clare runs 4 miles.
On the other six days, she runs the same distance, let's call it D.
In total, she runs 22 miles.
Then:
4mi + 6*D = 22 mi
6*D = 22mi - 4mi = 18mi
D = 18mi/6 = 3mi.
Then the other 6 days, Clare runs 3 miles

Graph m(x) on a coordinate plane to determine whether or not the function represents a direct variation. In complete sentences, describe your conclusion and reasoning. Include your graph in your answer.
Answers
Answer:
m(x) = 1.5x . . . . direct variation
Step-by-step explanation:
You want to know if the function m(x) represents direct variation, given a table of values.
Direct variationAn equation for direct variation is ...
y = kx
where k is a constant that can be found as the ratio of any (x, y) pair:
k = y/x
k = -1.5/-1 = 1.5/1 = 3/2 = 6/4 = 1.5
The ratios are constant, hence m(x) is direct variation with a constant of variation of 1.5.
GraphThe graph of direct variation is a straight line through the origin. The given points lie on such a line.

Using the coordinates given i put them into the formula:
y1 - y2
m=_________
x1 - x2
That gave me -16/-12, I simplified & got 4/3.
To find the slope you need at least two points on a line
The formula would be m=y2-y1/x2-x1
16-0/12-0
16/12
Simplified we would divide by 4 since it goes into both numbers

A cylindrical of oatmeal canister has a diameter of 4 inches and a height of 10 inches. The manufacturing company wants to package the oatmeal in square containers to cut back on wasted storage space. If the new carton has a square base with 4 inch sides, what is the minimum height it must have, to the nearest 1/4 inch, to hold the same volume of oatmeal? Use 3.14 for the value of π.
Answers
Step-by-step explanation:
Volume of cylinder = pi r^2 h
Volume of square container = s x s x h
they need to be equal
pi r^2 h = s^2 h
pi (2)^2 * 10 = 4^2 h (diameter = 4 then radius = 2)
40pi / 16 = h = 7.9 in = ~ 8 in to the nearest 1/4 inch

Solve the inequality d/4 > 36 for d
A. d < 9
B. d < 144
C. d > 144
D. d > 9
Answers
Answer: D. d > 9
Step-by-step explanation:
We have the inequality:
d/4 > 36
To solve for d, we need to isolate the variable d on one side of the inequality. We can do this by multiplying both sides of the inequality by 4:
d > 36 x 4
d > 144
Therefore, the answer is (D) d > 9, since any value of d greater than 9 would satisfy the inequality. We can also check that the other answer choices are incorrect:
If d < 9, then d/4 < 9/4, which is less than 36. So, (A) d < 9 is not a valid solution.
If d < 144, then d/4 < 144/4 = 36, which is less than 36. So, (B) d < 144 is not a valid solution.
If d > 144, then d/4 > 144/4 = 36, which satisfies the inequality. So, (C) d > 144 is also a valid solution, but not the most inclusive one.
Answer:
the correct answer is option C: d > 144.

The price of a technology stock was $9.79 yesterday. Today, the price fell to $9.66. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
Answers
Answer: 1.3%
Step-by-step explanation:
The percentage decrease can be found using the formula:
percentage decrease = [(original value - new value) / original value] x 100%
Substituting the given values:
percentage decrease = [(9.79 - 9.66) / 9.79] x 100%
percentage decrease = 1.33%
Rounding to the nearest tenth of a percent, the percentage decrease is 1.3%.
Answer: hope this helps ♡
The percentage decrease is 1.33%.
Step-by-step explanation:
Percentage decrease: dividing the value by the total value and then multiplying it by 100
Total value: $9.79 Value: $9.79 - $9.66 = 0.13
[tex]\frac{0.13*100}{9.79}[/tex] =
(0.13 × 100) ÷ 9.79 =
13 ÷ 9.79 =
1.32788559755 ≈ 1.33%
