Answer:
2250ml
Step-by-step explanation:
The concentrate-to-water ratio is 2:9. This means 2ml of concentrate requires 9ml of water. We have 500ml of concentrate, which is 250 times more than 2ml, so to find the amount of water, we also multiply 9ml by 250:
2ml concentrate : 9ml water
(Multiply both sides by 250)
500ml concentrate : 2250ml water
With a combined volume of a 4-foot cube and a 6-foot cube equal to the volume of a 10-foot cube? Use a diagram to justify your answer.
The combined volume of a 4-foot cube and a 6-foot cube is not equal to the volume of a 10-foot cube.
What is the volume of the cube?The volume of a cube is calculated by cubing the length of its side.
here,
Let's denote the length of the sides of the 4-foot and 6-foot cubes as "a" and "b", respectively. Then the length of the side of the 10-foot cube is "c", and we know that:
a³ + b³ = c³
We want to confirm if the combined volume of a 4-foot cube and a 6-foot cube is equal to the volume of a 10-foot cube. We can calculate the volumes of the cubes as follows:
Volume of 4-foot cube: a³ = 4³ = 64 cubic feet
Volume of 6-foot cube: b³ = 6³ = 216 cubic feet
Volume of 10-foot cube: c³ = 10³ = 1000 cubic feet
The sum of the volumes of the 4-foot and 6-foot cubes is:
64 + 216 = 280
Therefore, the combined volume of a 4-foot cube and a 6-foot cube is not equal to the volume of a 10-foot cube.

The altitude of an airplane coming in for a landing is represented by the equation shown below, where y represents the altitude,
in feet, of the airplane and x represents the number of minutes the plane has been descending:
y=-1025x + 30,750
Part A:
Create a table for the values when x = 0, 5, 8, 10, 30.
Include worked-out equations used to identify the values within the table.
Part B:
Identify the altitude after 5 minutes and after 30 minutes. Use 1-2 sentences to explain the altitude at these two times and
describe what is happening to the airplane at these time intervals.
Part A:
Look at photo
Part B:
After 5 minutes, the altitude of the airplane is 20,500 feet. This means that the airplane has been descending for 5 minutes and has lost an altitude of 10,250 feet.
After 30 minutes, the altitude of the airplane is -29,250 feet. This means that the airplane has been descending for 30 minutes and has lost an altitude of 60,000 feet. The negative value of the altitude indicates that the airplane has landed or is close to landing.
At both 5 minutes and 30 minutes, the airplane is descending. The rate of descent is constant, as represented by the slope of the equation, and is equal to -1025 feet per minute. At 5 minutes, the airplane is still at a high altitude, while at 30 minutes the airplane has landed or is close to landing, as indicated by the negative value of the altitude.
Answer:
Step-by-step explanation:
Part A:
x | y | Equation
0 | 30,750 | y = -1025*0 + 30,750
5 | 27,250 | y = -1025*5 + 30,750
8 | 23,750 | y = -1025*8 + 30,750
10 | 20,250 | y = -1025*10 + 30,750
30 | -20,250 | y = -1025*30 + 30,750
Part B:
After 5 minutes, the altitude is 27,250 feet. This means that the airplane has been descending steadily for 5 minutes and is now at a lower altitude than when it started.
After 30 minutes, the altitude is -20,250 feet. This means that the airplane has been descending steadily for 30 minutes and is now much lower than when it started. The airplane is close to the ground and about to land.
Will your battery capacity go down if you update your iphone?
Unfortunately, a lot of software apps tend to use up battery life even if you aren't currently using the phone. This leads to the phone feeling more sluggish over time. To help combat this, it's helpful to clear out any unused apps and clear up the cache.
Even if software was perfectly written the most efficiently, and apps weren't intrusive, the physical nature of the battery itself has limitations. The capacity of the battery will slowly decay each time you charge or use your phone. Even just sitting idle it slowly loses capacity. This loss is very small that it's hard to detect. But add it up over time and the losses will get more noticeable. This is why you cannot simply charge a battery an infinite number of times. As with all things in life, there's a limit.
Summary: Yes the capacity will go down but ever so slightly. It depends how often the updates are done and what software is being updated. Ideally the updated software should be more efficient with the battery life. However, life isn't perfect and there will likely be flaws.

Answer:
6) x = 6
7) x = 4
8) x = 4
9) x = 6
10) x = 6
Step-by-step explanation:
This is based on Dr. Henry Borenson's method of using pawns to explain algebraic equations. Frankl I find using variables more intuitive
Let each pawn represent an x in the equations
6.
x + 8 = 10 + 4
x = 10 + 4 - 8
x = 14 - 8 = 6
7.
x + x = 4 + x
2x = 4 + x
2x - x = 4
x = 4
8.
x + x + x + 2 = 7 + 7
3x + 2 = 14
3x = 14 - 2
3x = 12
x = 12/3
x = 4
9.
2x + 4 = x + 10
2x - x = 10 - 4
x = 6
10
3x = x + 10 + 2
3x = x + 12
3x - x = 12
2x = 12
x = 6
Find the value of x.
The angles x and 3x - 12 are two vertical angles and the measure of the vertical angle x is equal to 48°.
What are vertically opposite anglesVertical angles also called vertically opposite angles are formed when two lines intersect each other, the opposite angles formed by these lines are vertically opposite angles and are equal to each other.
We shall evaluate for the measure of x as follows:
x + x + 3x - 12 + 3x - 12 = 360° {sum of angles at a point}
2x + 6x - 24 = 360°
8x - 24 = 360°
8x = 360° + 24 {add 24 to both sides}
8x = 384°
x = 384°/8 {divide through by 8}
x = 48°
Therefore, since the angles x and 3x - 12 are two vertical angles we have derived the measure of the vertical angle x to be equal to 48°.

A rectangular room is 2 meters longer than it is wide, and its perimeter is 24
meters. Find the dimension of the room.
The length is : _____ meters and the width is _____
meters.
If a rectangular room is 2 meters longer than it is wide, and its perimeter is 24 meters then the dimensions of the room: 7 meter x 5 meter
What is the perimeter?Perimeter is a mathematical term, it indicates total outer boundary of a figure, we define it only for two dimensional figures.
Perimeter = Sum of length of the all the sides
Let x be the width of the room in meters.
Then the length of the room is 2 meters longer, which means it is x+2 meters.
In this case, we know that the perimeter is 24 meters.
So we can set up an equation:
Perimeter = 2Length + 2Width
Substituting the values we know:
24 = 2(x+2) + 2x
Simplifying the equation:
24 = 2x + 4 + 2x
24 = 4x + 4
20 = 4x
x = 5
So the width of the room is 5 meters, and the length is x+2 = 7 meters.
Therefore, the dimensions of the room are 7 meters by 5 meters.

The minimum length of the box to hold the smaller mirror is 10 inches for largest mirror fits in a box that is 18 inches wide by 20 inches long her smaller mirror.
What is proportion ?
In mathematics, proportion refers to the equality of two ratios. Two ratios are said to be proportional if they have the same relative size, meaning they represent the same relationship between quantities.
For example, if we have two ratios, such as 2/3 and 4/6, they are proportional because they represent the same relationship between two quantities. We can say that 2 is to 3 as 4 is to 6, and we can simplify both ratios by dividing the numerator and denominator of each by their greatest common factor, which in this case is 2.
Since the smaller mirror is similar in proportion to the larger mirror, the ratio of their corresponding sides is the same. Therefore, the width of the smaller box is half of the width of the larger box (9 inches is half of 18 inches).
To find the minimum length of the smaller box, we need to use the same ratio of sides. The length of the larger box is 20 inches, so the length of the smaller box should be half of 20 inches, which is 10 inches.
Therefore, the minimum length of the box to hold the smaller mirror is 10 inches.

If sin t= 7/9, and t is in quadrant I, find the exact value of sin(2t) , cos(2t) , and tan(2t) algebraically without solving for t .
Step-by-step explanation:
we know :
sin(2t) = 2×sin(t)×cos(t)
cos(2t) = cos²(t) – sin²(t) = 2×cos²(t) – 1 = 1 – 2×sin²(t)
tan(t) = sin(t)/cos(t)
tan(2t) = sin(2t)/cos(2t) = (2×tan(t))/(1 – tan²(t))
sin²(t) + cos²(t) = 1
as t is in quadrant I, 2t must be in either quadrant I or II.
sin(t) = 7/9
sin²(t) = (7/9)² = 49/81
cos²(t) = 1 - sin²(t) = 1 - 49/81 = 81/81 - 49/81 = 32/81
cos(t) = sqrt(32)/9
sin(2t) = 2×sin(t)×cos(t) = 2×7/9 × sqrt(32)/9 =
= 14×sqrt(32)/81 ≈ 0.98
cos(2t) = cos²(t) - sin²(t) = 32/81 - 49/81 = -17/81 ≈
≈ -0.21
tan(2t) = sin(2t)/cos(2t) =

A bag of garden soil weighs 42 pounds and holds 2 cubic feet. Find the weight of 15 bags in kilograms and the volume of 15 bags in cubic yards.
Answer:
285.76 kilograms 1.1 cubic yard
Step-by-step explanation:
Answer:
1.11121 cubic yards.
Step-by-step explanation:
First, let's convert the weight of 1 bag of garden soil from pounds to kilograms:
1 lb = 0.45359237 kg
42 lbs = 42 * 0.45359237 kg = 19.05 kg
So, the weight of 1 bag of garden soil is 19.05 kilograms.
Next, let's find the weight of 15 bags of garden soil:
15 bags * 19.05 kg/bag = 285.75 kg
So, 15 bags of garden soil weigh 285.75 kilograms.
Next, let's find the volume of 15 bags of garden soil in cubic yards:
1 cubic foot = 0.037037 cubic yards
2 cubic feet * 15 bags = 30 cubic feet
30 cubic feet = 30 * 0.037037 cubic yards = 1.11121 cubic yards
So, 15 bags of garden soil have a volume of 1.11121 cubic yards.

Jll company in 2012 had sales of 800,000 in 2022 sales were up 75% . Calculate the sales for 2021.
Answer:
860,000.
Step-by-step explanation:
If the sales in 2022 were up 75% from 800,000, the sales in 2022 would be 800,000 + (800,000 * 75%) = 800,000 + 600,000 = 1,400,000.
To find the sales for 2021, we'll have to use the average annual growth rate to find the sales in between 2012 and 2022.
Let's assume that the sales grew linearly, so the average annual growth rate would be (1,400,000 - 800,000) / (2022 - 2012) = 600,000 / 10 = 60,000.
The sales in 2021 would then be 800,000 + 60,000 = 860,000.

After Amal gives one third of his sweets to Balu, Balu's number of sweets becomes x + (1/3)x = (4/3)x.
After Balu gives one third of his sweets to Chandran, Chandran's number of sweets becomes 40 + (1/3)(4/3)x = 40 + (1/3)x.
After Chandran gives one third of his sweets to Amal, Amal's number of sweets becomes (2/3)x + (1/3)(40 +(1/3)x) = (2/3)x + (1/3)x + 40/3 = (5/3)x + 40/3.
Since all three of them now have the same number of sweets, we can set the number of sweets each of them has equal:
(4/3)x = (5/3)x + 40/3.
Now, we will isolate x by rearranging the equation. Subtracting (5/3)x from both sides, we get:
(4/3)x - (5/3)x = 40/3
Simplifying the left side:
-x/3 = 40/3
Dividing both sides by -1/3:
x = 40
Thus, Balu originally had 40 sweets.
