Answer:
2325 mL
Step-by-step explanation:
Let x = total volume of the tank. When we fill 4/5 of water into the tank, the amount of water we have can be expressed by 4x/5. Then we only keep 1/3 of that amount (poured away 2/3 of the water), so the amount of water is 4x/15. Thus we set up the equation like this:
4x/15 = 620
4x = 9300
x = 2325
Thus the tank can contain a maximum of 2325 mL.

20 points for answer!
Answer:
VVV
Step-by-step explanation:
A number that is increased by 50% and then decreased by 50% is called sequential percentage calculation or successive percentage calculation.
50 percent minus 50 percent is 0 percent, but you cannot simply take 0 percent of a number to get the correct answer when you want to increase a number by 50 percent and then decrease the result by 50 percent.

Answer:
x must be 4
Step-by-step explanation:
Write and solve an equation of ratios. Start with the ratio of the hypotenuses:
x + 2 x
----------- = --------
x + 5 x + 2
Cross multiplying results in (x + 2)^2 = x^2 + 5x
performing the indicated squaring, (x + 2)^2 = x^2 + 4x + 4. And therefore:
x^2 + 4x + 4 = x^2 + 5x
Simplifying, we get 4x + 4 = 5x, so x must be 4

Answer:
105 minutes
Step-by-step explanation:
The pond is a prism. Its volume is the area of the trapezoidal base (the front and back faces) multiplied by the height (the 1 m edge).
Area of base of pond (front face) = (1/2)(B + b)h
Base = (1/2)(1.5 m + 0.6 m)(2 m) [Here, height is the height oif the trapezoid, so it is 2 m]
Base = 2.1 m²
Volume = Base × Height
Volume = 2.1 m² × 1 m [Here, height is the height of the prism, so it is 1 m]
Volume = 2.1 m³
The volume of the upper 30 cm (= 0.3 m) of the pond is:
V = LWH
V = 2 m × 1 m × 0.3 m
V = 0.6 m³
The volume of water decreased 0.6 m³ in 30 minutes.
In 60 minutes, it would decrease by 1.2 m³.
60 minutes = 1 hour
The flow rate is 1.2 m³ / hour.
The total volume of the pond is 2.1 m³.
Emptying out the pond completely means removing 2.1 m³ of water at the flow rate of 1.2 m³/hour.
flow rate = volume/time
time × flow rate = volume
time = volume / flow rate
time = 2.1 m³ / 1.2 m³/hour = 1.75 hour
time = 1.75 hour × 60 minutes/hour = 105 minutes
Answer: 105 minutes

Hi!
The ratio in the picture is 3:12. There are 3 tbsp of vinegar for every 12 tbsp of water.
[tex]\frac{3}{12}[/tex] can be simplified to [tex]\frac{1}{4}[/tex] by dividing the numerator and denominator by 3.

A seesaw is 3 metres long. It is balanced when child A sits 0.8 m from the pivot and child B sits 0.6 m from the pivot. Child A has a weight of 300 N. i. Draw a force diagram to represent this system. (Ensure that you label the force and distances given.) ii. Use the principle of moments to determine the weight of child B.
Answer:
i) see attached diagram
ii) 400 N
Step-by-step explanation:
Since we don’t know the mass of the seesaw, take moments about M (so we don’t have to consider R or mg).
Moment = Force x Perpendicular Distance to the Pivot
As the system is in equilibrium, total anti-clockwise moment = total clockwise moment:
⇒ 300 × 0.8 = b × 0.6
⇒ 0.6 b = 240
⇒ b = 400 N

Answer:
y = 28°
Step-by-step explanation:
The triangle is a right triangle which has 90 degrees.
The 3x falls under 90 degrees.
So:
→ 2y + 90° + 34° = 180°
→ 2y = 180° - 124°
→ 2y = 56°
→ y = 28°
Triangle
XYZ = right triangle
3x = 90°
X + Y + Z = 180°
34° + 3x + 2y = 180°
34° + 90° + 2y = 180°
2y = 180° - (34° + 90°)
2y = 56°
y = 28°

Two cars leave a rest stop at the same time and proceed to travel down the highway in the same direction. One travels at an average rate of 49 miles per hour, and the
other at an average rate of 68 miles per hour. How far apart are the two cars after 4.5 hours?
Answer:
The answer is going to be 85.5 miles apart.
Step-by-step explanation:
if the first car is going 49 miles for every hour and the second at 68 we now have our two numbers. then we know its 4.5 hours so our equation goes like this.
(68*4.5)-(49*4.5)=y
We do our rules with pemdas and what not.
we get
306-220.5=y
We subtract and bam
y= 85.5 miles apart.

Jackson made a drawing for his residence including a villa and a garden, as in the given figure. Using the scale drawing, what is the perimeter of the villa in real life?
Answer:
60 meters.
Step-by-step explanation:
Here the villa has length of 6 cm and breadth of 4 cm
Find perimeter using:
2(length + breadth)
2(6 + 4)
20 cm
Here in scale the drawing perimeter is 20 cm
3 meter = 300 cm ......this is for real.
1 cm here --> 20 cm
300 cm in real --> (20*300) cm
Real perimeter = 6000 cm
If 6000 cm converted to m:
(6000/100) = 60 meters.
Find perimeter using:
[tex]2(length + breadth)[/tex]
[tex]2(6+4)[/tex]
[tex]20 cm[/tex]
Here in scale the drawing perimeter is [tex]20 cm[/tex]
[tex]3 meter = 300 cm [/tex]
[tex]1 cm → 20 cm[/tex]
[tex]300 \: cm → (20×300) cm[/tex]

The owner of an orange grove must decide when to pick one variety of oranges. She can sell them for $24 a bushel if she sells them now, with each tree yielding an average of 4 bushels. The yield increases by half a bushel per week for the next 5 weeks, but the price per bushel decreases by $1.50 per bushel each week. In how many weeks should the oranges be picked for maximum return?
Answer:
4
Step-by-step explanation:
Let's say the amount of bushes sold (yield) is b, and the price per bushel is p.
When calculating total revenue, we want to multiply price by quantity. Quantity here is b, and price is p. Therefore, p*q = revenue = return.
Let's say that the amount of weeks is w.
Price after w weeks = 24 - 1.50 for each week = 24 - 1.50w
Yield after w weeks = 4 + 0.5 for each week = 4 + 0.5w
Revenue after w weeks = p * b = (24-1.50w) * (4+0.5w) = 96 - 6w + 12w - 0.75w² = -0.75w²+6w + 96.
We want to maximize revenue. First, we can find when the derivative of the function is 0.
d/dw(-0.75w²+6w + 96) = -1.5w + 6 = 0
subtract 6 from both sides
-1.5w = -6
divide both sides by -1.5 to isolate w
w = 4
plug that into our equation
-0.75(4)²+6(4) + 96 = -12 + 24 + 96 = 108
Because this function has a negative coefficient for the w², we can say that it is a parabola opening up downward, so when the derivative = 0, we have found the maximum of the function. Therefore, 4 is our answer
