First, we see that at 0 minutes, the container is completely full at 900ml. If you look on the graph, you can see that the container is at 800ml after 10 minutes. This is key because it tells us that the container leaks 100ml every 10 minutes. We can then figure up that 900, when losing 100ml every 10 minutes, will eventually run dry after 90 minutes. You can set up a proportion to check your work, which would look like this: 10 over 100 is equal to x over 900.

Suppose you work for a large coffee distributor that has a secret coffee blend it sells to local stores. You
mix the Tanzanian blend with the Queen City blend, but always in the same proportion. Yesterday, you
mixed 40 pounds of the Tanzanian blend with 8 pounds of the Queen City blend. Today, there is 20 pounds
of the Tanzanian coffee left in stock. How many pounds of the Queen City coffee should you mix with it to
get your secret blend?
Answers
Quantity of Tanzanian blend used in my secret coffee blend = 40 pounds
Quantity of Queen city blend used in my secret coffee blend = 8 pounds
The ratio of Tanzanian blend to Queen city blend in my coffee blend = 40 : 8
Quantity of Tanzanian blend with me = 20 pounds
Quantity of Queen city bend needed to make my secret coffee blend =
Let the quantity of Queen city blend I will need be x .
[tex] \frac{40}{8} = \frac{20}{x} [/tex]
[tex]8 \times 20 = 40 \times x[/tex]
[tex]160 = 40x[/tex]
[tex]x = \frac{160}{40} [/tex]
[tex]x = 4[/tex]
Therefore , I need to mix 4 pounds of queen city blend with my 20 pounds of Tanzanian blend to get my secret coffee blend .
4 pounds of the Queen City coffee should you mix with it to get your secret blend.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given that,
Yesterday If we mixed 40 pounds of the Tanzanian blend with 8 pounds of the Queen City blend.
In the same proportion, today there is 20 pounds of the Tanzanian coffee left in stock.
We need to calculate how many pounds of the Queen City coffee should you mix with it to get your secret blend.
Let x be the pounds of the Queen City coffee should you mix with it
Let us form a equation
40/8=20/x
Apply cross multiplication
40x=160
Divide both sides by 40
x=4
Hence 4 pounds of the Queen City coffee should you mix with it to
get your secret blend.

Answer:
x= 3, y= 8
or x= -1, y= 0
Step-by-step explanation:
y= 2x² -2x -4 -----(1)
y -2x= 2
y= 2x +2 -----(2)
Substitute (1) into (2):
2x² -2x -4= 2x +2
2x² -2x -4 -2x -2= 0 (bring all terms to the left)
2x² -4x -6= 0 (simplify)
x² -2x -3= 0 (÷2 on both sides)
(x -3)(x +1)= 0 (factorise)
x -3= 0 or x +1= 0
x= 3 or x= -1
Substitute into (2):
y= 2(3) +2 or y= 2(-1) +2
y= 6 +2 or y= -2 +2
y= 8 or y= 0
An aircraft factory manufactures airplane engines. The unit cost (the cost in dollars to make each airplane engine) depends on the number of engines made. If engines are made, then the unit cost is given by the function . What is the minimum unit cost?C(x)=x^2-520x+73458
Answers
Answer:
Minimum unit cost = 5,858
Step-by-step explanation:
Given the function : C(x)=x^2−520x+73458
To find the minimum unit cost :
Take the derivative of C(x) with respect to x
dC/dx = 2x - 520
Set = 0
2x - 520
2x = 520
x = 260
To minimize unit cost, 260 engines must be produced
Hence, minimum unit cost will be :
C(x)=x^2−520x+73458
Put x = 260
C(260) = 260^2−520(260) + 73458
= 5,858

Answers
Answer:
10,500.93 feet
Step-by-step explanation:
From the question, we are told that Tom walks 3.2km every morning.
1 mile = 1.609km
1 mile = 5280 feet
Step 1
1.609km = 1 mile
3.2km = x mile
Cross Multiply
x mile × 1.609km = 3.2km × 1 mile
x mile = 3.2km × 1 mile/1.609.
= 1.9888129273 miles
1 mile = 5280 feet
1.9888129273miles = y
Cross Multiply
y = 1.9888129273 × 5280 feet/1 mile
= 10500.932256 feet
Approximately = 10,500.93 feet
Therefore, Tom walks for 10,500.93 feet

Given the following :
Initial speed (u) = 1 m/s
How long does it take the bean bag to reach maximum height?
At maximum height, the final velocity v = 0
Acceleration due to gravity g = - ve (upward motion) =? - 9. 8m/s²
Using the relation:
v = u + gt

Step-by-step explanation:
(4, 5) is 4 units to the right of the y-axis and 5 units above the x-axis.
When you reflect point (4, 5) over the x-axis, the new point is still 4 units to the right of the y-axis, so its x-coordinate is still 4. The distance that was above the x-axis now is below the x-axis, so the y-coordinate is -5.
