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%
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

Haven't done this kinda problem in a while but I got 4/3 cm/s
Step-by-step explanation:
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
4/3 as the answer

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.

Answers
Answer:
There are 55 large boxes
and 70 small boxes.
Step-by-step explanation:
Let's assume that the number of large boxes is x, and the number of small boxes is y. We then can use how many pounds each box weighs to form a system of equations.
System:
[tex]50x+25y=4500\\x+y=125[/tex]
Step 1: Solve for a variable
[tex]x+y=125[/tex] is also [tex]y=-x+125[/tex]
Step 2: Substitute
[tex]50x+25(-x+125)=4500[/tex]
Step 3: Simplify
[tex]50x+-25x+3125=4500\\25x=1375\\x=55[/tex]
Step 4: Solve for y
[tex]y=-55+125\\y=70[/tex]

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

A school board randomly samples 80 students to determine their opinion on requiring school uniforms for the next school year. The table shows the results of the survey.
If there are 3,000 students in the district, how many students do you expect to be undecided about school uniforms?
Answers
Answer: 900
Step-by-step explanation:
If 24 out of 80 students are undecided, that is 24/80, or 3/10 (0.3).
To find how many would be undecided out of 3,000 students, multiply 3/10 by 3,000/1, and you get 900, which is your answer

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.
