Q

Answer:  

Step-by-step explanation:

The fraction of the solution present in the contaminant is 3/5.

First, we convert 50% to fractions.

Changing a percentage to a fraction is equivalent to dividing a number by 100.

500% = 500/100

Taking this into account, we get 3/(500/100).

Then, when we divide a number by a fraction, we multiply the result by the inverse of the fraction.

= 3/(500/100)

= 3 x 100/500

Further simplifying;

= 300/500

= 3/5

Therefore, the value of the fraction of contaminant solution is 3/5.

The dimensions of the rectangle are 59 by 50 inches

The given parameters are

Length (l) = 1/2 width (w) + 9

Perimeter (P) = 318

Perimeter is calculated as

P = 2 (l + w)

Substitute l = 1/2w + 9 in P = 2(l + w)

So, we have

2 * (1/2w + w + 9) = 318

Evaluate the like terms

2 * (1.5w + 9) = 318

Divide by 2

1.5w + 9 = 159

So, we have

1.5w = 150

Divide by 15

w = 100

Substitute w = 100 in l = 1/2w + 9

l = 1/2 * 100 + 9

Evaluate

l = 59

Hence. the dimensions of the rectangle are 59 by 50 inches

The boiling point of water is 256 °F warmer than the boiling point of liquid propane.

In the question, we are given that the boiling point of a liquid is the temperature at which the liquid starts to boil. The boiling point of water is 212°F. Propane gas is used for cooking in gas grills. Liquid propane has a boiling point of -44°F.

We are asked to find how much warmer the boiling point of water is than the boiling point of liquid propane.

To find the warmth of the boiling point of water in comparison to the boiling point of liquid propane, we subtract the boiling of liquid propane from the boiling point of the water.

Thus, The warmer the boiling point of water is in comparison to the boiling point of liquid propane = The boiling point of water - The boiling point of liquid propane,

or, The warmer the boiling point of water is in comparison to the boiling point of liquid propane = 212 °F - ( -44 °F),

or, The warmer the boiling point of water is in comparison to the boiling point of liquid propane = 212 °F + 44 °F = 256  °F.

Thus, the boiling point of water is 256 °F warmer than the boiling point of liquid propane.

The slope associated with points (2, 6) and (-1, 3) is 1 so it is not a negative slope.

A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

Given the points,

(2, 6) and (-1, 3)

The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by

Slope = (y₂ - y₁)/(x₂ - x₁)

So,

Slope = (3 - 6)/(-1 - 2)

Slope = (-3)/(-3) = 1

Step-by-step explanation:

A line has a function:

y = ax + b

The length of the hypotenuse in this right-angled triangle =  6.98 cm².

The Pythagorean theorem states that the total of the squares on the legs of a right triangle equals the square upon that hypotenuse (the side opposite the right angle)—or, in popular algebraic notation, a2 + b2 = c2.

The basic formula for calculating the area of a triangle is the half square product of its base as well as height, i.e., A = 1/2 b h. This formula applies to all triangles, whether they are scalene triangles, isosceles triangles, or equilateral triangles.

Hypotenuse (c) = 8 cm

Base (b) = 3.9 cm

Length =

C² = (a² + b³)

a² = C² - b²

a = √((8)² - (3.9)²)

The pressure of the circular table top has a radius of 90 cm. A force of 810 N is applied to the whole table top =  287.23 N/m².

A force seems to be an influence that could also cause an object's motion to change. A force can cause a mass item's velocity or acceleration to alter. The force can be expressed intuitively as a push or perhaps a pull. Because it has both magnitude and direction a force is a vector quantity.

The force applied against the surface of an item per unit area across which that force is spread is referred to as pressure (symbol: p or P).

Force = 810N

Radius of the circular table = 90cm.

Pressures  = force /area

Finding the area of circular table = πr²

                                                       = π x 90 x 10⁻² (1 cm = 10⁻²)

                                                       = 2.82 m²

substituting the value in the formula.

Pressures  = force /area

                  = 810/2.82

                  = 287.23 N/m²

Ashley and her four friends will need 5 hours and 19.57 minutes to make 1575 bags if Ashley takes 2/3 of a minute and each friend takes 75% longer.

The first sexagesimal fraction of an hour, or one-fifth of an hour, or 60 seconds, is known as the minute. On rare occasions, due to leap seconds, a minute in the UTC time zone has 61 seconds (A negative leap second might be inserted, producing a minute of 59 seconds; however, this has never occurred in more than 40 years under this system.) The minute can be used with SI units even if it isn't a SI unit. Minute or minutes is represented by the SI unit min (without a dot). Occasionally, people would slangy refer to minutes of time by the prime symbol.

Calculations:

For a bag, Ashley needs about 2/3 of a minute.

Her friends takes 75%  Longer to prepare a bag

time taken by her friends =  2/3  + (75/100)(2/3)

Based on the calculations, the sum of the areas of the rectangles is equal to: A. 0.25 square unit.

Mathematically, the area of a rectangle can be calculated by using this formula;

A = LW

Where:

By critically observing the figure (see attachment), we can logically deduce the following information:

Width of rectangle A = 2 units

Width of rectangle B = 2 units.

Width of rectangle C = 4 units.

Next, we would determine the length and area of each of the rectangle.

The length of the first rectangle is given by:

Length of rectangle, y = 3^-x

Length of rectangle, y(0) = 3⁻⁰ = 1 units.

Length of rectangle, y = 3^-x

Length of rectangle, y(2) = 3⁻² = 0.11 unit.

Area of first rectangle = 2(0.11)

Area of first rectangle = 0.22 square unit.

For the second rectangle, we have:

Length of second rectangle, y = 3^-x

Length of second rectangle, y(4) = 3⁻⁴ = 0.012 unit.

Area of second rectangle = 2(0.012)

Area of second rectangle = 0.025 square unit.

For the third rectangle, we have:

Length of third rectangle, y = 3^-x

Length of third rectangle, y(8) = 3⁻⁸ = 0.00015 unit.

Area of third rectangle = 4(0.00015)

Area of third rectangle = 0.0006 square unit.

Now, we can calculate the sum of the areas of the rectangles:

Total area = 0.22 square unit + 0.025 square unit + 0.0006 square unit.

Total area = 0.246 ≈ 0.25 square unit.

Total area of rectangle = 0.25 square unit.
