Answer:

Sofia has a total of 7 cups + 1 cup = 8 cups of paint.

The proportion of red paint to the total amount of paint is 1 cup / 8 cups = 1/8.

So the fraction representing the proportion of red paint out of the total amount of paint is 1/8.

Answer: 1/8

Step-by-step explanation:

She uses 8 cups of paint and one of those 8 cups is red so it would be 1 red cup out of 8 cups or 1/8

The estimation helps us to get simpler digits to perform operations.

An approximate value close enough to the correct value is called estimation.

Given that, how can an estimate help when multiplying 5.3 x 3.9

So, here we see that, multiplication of two decimal number are getting performed,

To multiply decimal numbers, sometimes gets lengthy, so we use estimation,

Here, the two numbers are, 5.3 and 3.9,

Rounding the numbers for estimation,

The rule of rounding says, that, when the digit after decimal is less than five then we round down and if it is greater than five then we round up,

Therefore,

5.3 = 5

3.9 = 4

Now, as we get two simpler numbers, we can easily multiply them

5 x 4 = 20

That mean, the estimated value of 5.3 x 3.9 is 20

Hence, the estimation helps us to get simpler digits to perform operations.

The required correct answers are;

1 - (1 1/3 x, 1 1/3 y)

4 - (3 1/10 x, 3 1/10 y)

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size.

The following algebraic rules represent a dilation that is an enlargement:

1 - (1 1/3 x, 1 1/3 y)

4 - (3 1/10 x, 3 1/10 y)

The scale factor in both of these rules is greater than 1, which means that the dilation is an enlargement. In rule 1, the scale factor is 1 1/3, and in rule 4, the scale factor is 3 1/10.

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

Given an expression that needs to be rewritten in simplified form

Equation is:

Solving the square root

=> x - 2 * x√x - x²- 4x + 12

The value of a is 12 when transversal t crosses over parallel lines p and s.

A transversal line is one that crosses two or more other lines. A transversal is frequently used in geometry to establish connections between angles created by crossing lines. When a transversal connects two parallel lines, it produces equivalent pairs of alternate interior and alternative exterior angles. These connections can be used to demonstrate the parallelism of two lines. In a broader sense, the term transversal refers to any line that meets another line, regardless of their angle connections. A transversal, for example, might be used to locate the point of intersection of two lines or to divide a form into two distinct pieces.

The standard form polynomial representing the volume of this shipping container is expressed as V = 24x⁵+78x⁴-147x³-624x²-360x

Volume of the shipping container = Lengt * Breadth * Height

Given

Length = 4x² + 3x

Breadth = x² – 8

Height = 6x +15

Volume of the container = ( 4x² + 3x)( x² - 8)(6x+15)

( 4x² + 3x)( x² - 8)  = 4x⁴-32x²+3x³-24x

( 4x² + 3x)( x² - 8) = 4x⁴+3x³-32x²-24x

(4x⁴+3x³-32x²-24x)(6x+15) = 24x⁵+60x⁴+18x⁴+45x³-192x³-480x²-144x²-360x

The inverse function of the given function is

              f ⁻¹(x)  = x³ + 15x² + 75x + 123

What are inverse functions?

A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function f will take y to x if any function f takes x to y. When a function is written as f or F, its inverse is written as f⁻¹ or F⁻¹.

The given function is ∛(x+2) - 5

One of the properties of the inverse function is

f( f ⁻¹ x) = x

We utilise this property to find f ⁻¹ x.

f(x) = ∛(x+2) - 5

f( f ⁻¹x) = ∛( f ⁻¹(x) + 2) - 5

Using the above property

x = ∛( f ⁻¹(x) + 2) - 5

x + 5 = ∛( f ⁻¹(x) + 2)

Cubing both sides,

(x+5)³ =  f ⁻¹(x) + 2

x³ + 15x² + 75x + 125 = f ⁻¹(x)  + 2

f ⁻¹(x)  = x³ + 15x² + 75x + 123

Therefore the inverse function of the given function is

Answer:

The area of a circle with a diameter of 5 m is 19.63 m², rounded to the nearest tenth, it would be 19.6 m². So the answer is c. 19.6 m².

What is circle ?

A circle is a two-dimensional geometric shape defined as the set of all points that are a fixed distance, called the radius, from a central point, called the center. A circle is the set of all points in a plane that are at a given distance from a given point, the center.

The area of a circle is given by the formula A = , where r is the radius of the circle. To find the area of a circle with a diameter of 5 m, we first need to find the radius. We can do this by dividing the diameter by 2:

r = 5 m / 2 = 2.5 m

Then we can substitute this value of r into the formula for the area of a circle:

A =  = π(2.5 m)^2 = 3.14 * 6.25 m^2 = 19.63 m²

So the area of a circle with a diameter of 5 m is 19.63 m², rounded to the nearest tenth, it would be 19.6 m². So the answer is c. 19.6 m².

The walking speed x = (L/t) - (3/65) L + (2/50) L .We can solve this problem using the concept of average speed and the time and distance relationship.

Let's assume the length of the moving sidewalk be L and the speed of the moving sidewalk be v.

When the moving sidewalk is working, the person's speed is v + w, where w is the walking speed.

And, the time taken to travel the distance L is 65s.

So, using the average speed formula, we have:

(v + w) = L/65

And, when the moving sidewalk is not working, the person's speed is w.

And, the time taken to travel the distance L is 50s.

So, using the average speed formula, we have:

w = L/50

Now, we can equate the above two equations to find the walking speed w.

v + w = L/65

w = L/50

Subtracting the second equation from the first equation, we get:

v = (L/65) - (L/50)

Since, L is common in both the numerators, we can simplify the above expression as:

v = (3/65 - 2/50) L

Thus, the speed of the moving sidewalk is (3/65 - 2/50) L.

Let's assume the walking speed be x.

So, the average speed of the person is (v + x) = (3/65 - 2/50) L + x.

And, the time taken to travel the distance L is t.

Using the average speed formula, we have:

(v + x) = L/t

Substituting the value of v, we get:

((3/65 - 2/50) L + x) = L/t

Simplifying the above equation, we get:

x = (L/t) - (3/65 - 2/50) L

Now, substituting the values of L/50 and L/65, we get:

x = (L/t) - (3/65 - 2/50) L

x = (L/t) - (3/65) L + (2/50) L

So, the walking speed x = (L/t) - (3/65) L + (2/50) L.

Therefore, the walking speed can be calculated using the above expression.
