Answer:
Length = 10 cm
Width = 10 cm
Height = 12 cm
Step-by-step explanation:
Cost of a cardboard with a square base and top = 0.3 cents per cm²
0.3 cents = $0.003 (0.3/100)
Total cost for material = $3.6
The volume of the box = $3.6/$0.003 = 1,200cm³
The formula for volume = length × width × height.
Since the base and top are square, the length and width must have equal sizes.
Let us assume that
length = 10cm
width = 10cm
these will give an area of 100cm².
Volume = length * width * height
= Area * height
= 10 * 10 * height
= 100cm² * height
Therefore, the height will be the volume divided by area
= 1,200cm³/100cm²
= 12cm
Volume = 10 * 10 * 12
= 1,200cm³

The function graphed above is:
Increasing on the interval(s)
Decreasing on the interval(s)
Answer:
[tex]Interval = (-2,1.5)[/tex]
[tex]Interval = (-\infty, -2)\ u\ (1.5,\infty)[/tex]
Step-by-step explanation:
Given
See attachment for graph
Solving (a): Increasing interval
To do this, we simply identify the interval at which the value of the graph increases.
The value has an increased interval between -2 and 1.5 (of the x-axis).
Hence, the increasing interval is:
[tex]Interval = (-2,1.5)[/tex]
Solving (b): Decreasing interval
To do this, we simply identify the interval at which the value of the graph decreases.
The value has decreased intervals between - infinity and -2 and also 1.5 and infinity (of the x-axis).
Hence, the decreasing interval is:
[tex]Interval = (-\infty, -2)\ u\ (1.5,\infty)[/tex]

if I have the numbers 8,4,11,13 and need a 5th number to make my mean 10 what would the blank number be?
Answer:
14
Step-by-step explanation:
If you want to solve this question, you would need to know the sum of your number right now and after you add the blank number.
First one is: 8 + 4 + 11 + 13 = 36.
Second one: Sum = mean x [how many numbers there are], which means:
sum = 10 x 5 = 50.
Then, subtract the 36 from 50, and you get the answer: 14.

For a concert event, there are $30 reserved seat tickets and $20 general admission tickets. There are 1500 reserved seats available, and fire regulations limit the number of paid ticket holders to 2800. The promoter must take in at least $61,000 in ticket sales. Find a system of inequalities describing the different numbers of tickets that can be sold. (Let x be the number of $30 tickets and y be the number of $20 tickets.) number of tickets sold
Answer:
The system of inequalities is as follows:
30x + 20y ≥ 61,000
x ≤ 1500
x + y ≤ 2800
x ≥ 0
y ≥ 0
Step-by-step explanation:
The system of inequalities can be explained as follows:
30x + 20y ≥ 61,000 <= Indicating a take in of at least $61,000 in ticket sales.
x ≤ 1500 <= Indicating that 500 reserved seats are available.
x + y ≤ 2800 <= Indicating limit of the paid ticket holders to 2800.
x ≥ 0 <= Indicating ticket x must be equal or greater than 0.
y ≥ 0 <= Indicating ticket y must be equal or greater than 0.

Have the conditions for inference been met?
A varsity swimmer at a large high school wants to
estimate the amount of time (in hours), on average,
athletes at this school train or practice each day. This
swimmer selects 10 members of her swim team and
asks them how many hours they typically train or
practice. Use the data to construct a 90% confidence
interval to estimate the true mean number of hours
athletes at this school train or practice each day.
No, the sample is not random.
No, the graph of the data shows skewness and has
outliers.
No, the 10% condition cannot be verified, because it
is not known how many seniors are in the
population.
Yes, the student selected a random sample; 10 is
less than 10% of the population of athletes, and the
graph of the data shows no clear skewness or
outliers.
0.5, 1, 1, 2, 2, 2, 2.5, 2.5, 3, 3
Answer: the answer is A
Step-by-step explanation: because the original question does not state that the swimmer “randomly selected” the members. It only says the swimmer “selects” 10 members. Therefore, it is A (The sample is not random)

In triangle PQR.
Sis the point on PR such that angle RSQ = 90°
RQ = 14 cm
RS -- 10 cm
SP - 5 cm
Work out the length of PQ.
PQ=11
PS^2+SR^2=QR^2
PS^2+PS^2=PQ^2
9514 1404 393
Answer:
11 cm
Step-by-step explanation:
The law of cosines can be helpful here. In order to find PQ, we must know the cosine of the angle R. Fortunately, SOH CAH TOA reminds us it is ...
Cos = Adjacent/Hypotenuse
cos(R) = 10/14 = 5/7
__
The law of cosines gives us the relation ...
PQ^2 = PR^2 +QR^2 -2·PR·QR·cos(R)
PQ^2 = 15^2 +14^2 -2(15)(14)(5/7) = 121
PQ = √121 = 11
The length of PQ is 11 cm.
_____
Alternate solution
This can be solved using the Pythagorean theorem twice.
QS^2 = QR^2 -SR^2 = 14^2 -10^2 = 96
PQ^2 = PS^2 +QS^2 = 5^2 +96 = 121
PQ = √121 = 11

Someone bless my day with answering this math question I’m stuck on it (photo)
Answer:
The answer is B.
Step-by-step explanation:
If xy + y² = 6, then the value of dy/dx at x= -1 is
Hi there!
[tex]\large\boxed{\text{At (-1, -2), }\frac{dy}{dx} = -\frac{2}{5}}}[/tex]
[tex]\large\boxed{\text{At (-1, 3), }\frac{dy}{dx} = -\frac{3}{5}}}[/tex]
We can calculate dy/dx using implicit differentiation:
xy + y² = 6
Differentiate both sides. Remember to use the Product Rule for the "xy" term:
(1)y + x(dy/dx) + 2y(dy/dx) = 0
Move y to the opposite side:
x(dy/dx) + 2y(dy/dx) = -y
Factor out dy/dx:
dy/dx(x + 2y) = -y
Divide both sides by x + 2y:
dy/dx = -y/x + 2y
We need both x and y to find dy/dx, so plug in the given value of x into the original equation:
-1(y) + y² = 6
-y + y² = 6
y² - y - 6 = 0
(y - 3)(y + 2) = 0
Thus, y = -2 and 3.
We can calculate dy/dx at each point:
At y = -2: dy/dx = -(-2) / -1+ 2(-2) = -2/5.
At y = 3: dy/dx = -(3) / -1 + 2(3) = -3/5.
