Which inequality is represented by this graph?
Answer:
y≤-1/3x+1
Step-by-step explanation:
Rise/run, aka the slope, would be 1/3 because you move down/up one, and to the side 3. It is -1/3 because the line is going up to down.
Since the y-intercept is 1, you would be adding 1 to the end of the equation.
Can someone please help me ?
Answer:
D
Step-by-step explanation:
Since it is 28 meters deep, it would be -28. And it increases 0.012 meters per minute, and time is t, so that would be 0.012t. So the equation is 0.012t - 28 = 30.

Three rooms have doors that are labelled "Unicorns", "Radioactive Dragons", and "Unicorns and Radioactive Dragons". You know that each door is incorrectly labelled. You are allowed to peek inside only one of the rooms exactly once, and then you have to make a decision.
Answer:
I will peek into one room and see if there is dragon, a unicorn or both present and then name the doors accordingly.
Step-by-step explanation:
The logic puzzle aims to create smart intelligence in kids. The three doors are wrongly labelled. If the door name is unicorn then there cannot be a dragon inside the door and if the door name is dragon then both cannot be present inside the door.

4. Marlene purchases dollars worth of stock on her broker's advice and pays her
broker a 1.5% broker fee. She sells her stock when it increases to y dollars two
years later, and uses a discount broker who charges $21 per trade.
A. Express Marlene's net proceeds algebraically.
Answer:
y - 1.015x - 21
Step-by-step explanation:
Given that:
Let worth of stock = x
Broker fee = 1.5% of x = 0.015x
Total cost incurred to purchase stock = x + 0.015x = 1.015x
Worth of stock after 2 years = y
Broker fee = $21 per trade :
Amount Realized from sale = y - $21
Net proceed = Amount Realized from sale - cost incurred to purchase
= (y - 21) - (1.015x)
= y - 21 - 1.015x
= y - 1.015x - 21

Answer:
705 cm
Step-by-step explanation:
Ron and Hermione are lifting feathers into the air with magic. Hermione can lift a feather 3,525
centimeters (cm) into the air. That is 5 times as high as Ron can lift a feather.
How high can Ron lift a feather with his magic?
Hermione = 3,525 cm
Hermione = 5 × Ron
Substitute Hermione = 3,525 cm into
Hermione = 5 × Ron
3,525 = 5 × Ron
Ron = 3,525 / 5
= 705
Ron = 705 cm
Answer: 705

Two containers are leaking water.Container A Leaked at a rate of 2/3 a gallon every 1/4 an hour. Container B leaked at a rate of 3/4 a gallon every 1/3 an hour. Which container is is losing water faster?
Answer:
container A is losing water faster
Step-by-step explanation:
Given;
the rate of water loss in container A = 2/3 a gallon every 1/4 an hour
the rate of water loss in container B = 3/4 a gallon every 1/3 an hour
Determine the rate of water loss for each container;
Container A:
Volume of water loss, V = 2/3 a gallon
time of water loss, t = 1/4 an hour = 15 minutes
rate of water loss, Q = V/t
[tex]Q = (\frac{2 }{3}\ gallon) *(\frac{1}{15 \ mins} )\\\\Q = \frac{2}{45}(\frac{gallon}{mins}) = 0.0444 \ gpm[/tex]
Container B:
Volume of water loss, V = 3/4 a gallon
time of water loss, t = 1/3 an hour = 20 minutes
rate of water loss, Q = V/t
[tex]Q = (\frac{3}{4} \ gallon)*(\frac{1}{20 \ mins})\\\\Q = \frac{3}{80} (\frac{gallon}{mins}) = 0.0375 \ gpm[/tex]
The rate of container A is higher than container B, thus container A is losing water faster

solve the system by Elimination x+8y=0 -4x-10y=22
Answer:
y = 1, x = -8
Step-by-step explanation:
[tex]x + 8y = 0\\-4x - 10y = 22[/tex]
we can multiply the top equation by 4 and cancel out the x's
[tex]4x + 32y = 0\\-4x - 10y = 22\\22y = 22\\y = 1[/tex]
[tex]x + 8(1) = 0\\x = -8\\-4(-8) - 10(1) \\32 - 10 = 22\\[/tex]

Answer:
C. 4
Step-by-step explanation:
The Y-intercept of a line is where the line intersects with the y-axis, it is also when x=0. To find the intercept simply go along the axis until you run into the line, in this case, you hit the line when y=4. If the intercept is not shown on the graph you can use the slope-point equation and then simplify for the intercept.

Step-by-step explanation:
Kelsey has to pay $200 to rent a booth at the craft fair. The materials for each pendant cost $7.80, and she plans to sell each pendant for $13.50. To make a profit, she must make more money than she spends. Kelsey has already made 10 pendants.
Part C
It takes Kelsey 5 hours to make 12 pendants. If she works 8 hours per day for 3 days before the craft fair, can she make enough additional pendants to sell so that she can make a profit of at least $50? Explain.
Step-by-step explanation:
Let's calculate how much she will spend:
She has to pay $200 for the rent.
She made 10 pendants that costed $7.80 each, that's a total of 10*$7.80 = $78.
Therefore, she will spend $200 + $78 = $278.
Let's define x as the amount of pendants she makes.
To make a profit, the amount of pendants she makes, multiplied by $13.50 that is the price, has to be greater than $280 added to the amount of pendants she makes, multiplied by $7.80 that is the cost.
We write that as
13.50x > 280 + 7.80x
Let's subtract 7.80x on both sides:
13.50x -7.80x > 280 + 7.80x - 7.80x
5.70x > 280
Now we divide by 5.70 on both sides:
5.70x/5.70 > 280/5.70
x > 49.1
To make profit, she needs to make and sell more than 49 pendants.
The length of a book cover is 28.3 cm and the width of the book cover is 21 cm. What is the minimum width?explain
Answer:
The minimum width of the book = 20.9 cm
Step-by-step explanation:
The length of the book cover = 28.3 cm
The width of the book cover = 21 cm
Given that the uncertainty in measurement should be included due to the likelihood of error in measurement, the uncertainty in measurement can be presented as follows;
Measurement = (Best estimate + Uncertainty) units
Whereby the display of the measuring device is limited to one decimal place, we can have the measurement of the width, w, as follows;
Width of the book = (21 ± 0.1) cm
The range of the width of the book is therefore 20.9 cm to 21.1 cm
The minimum width of the book = 20. cm
3. A random survey of the quality of Raleigh city parks is taken. Sixty-five percent of the people surveyed were pleased with the condition of the parks. If 280 people were surveyed, then how many were pleased?
Answer: 182 people
Step-by-step explanation:
The following can be deduced from the question:
Number of people surveyed = 280
Percentage of people pleased = 65%
The number of people that were pleased will be:
= Percentage of people that were pleased × Number of people surveyed
= 65% × 280
= 65/100 × 280
= 0.65 × 280
= 182
182 people were pleased with the condition of the park
