Our friend's mistake when wanting to make a new mixture of pink paint is that she is only going to add 2 parts of white paint, the correct formula would be 3.

Painting is the practice of applying paint, pigment, color or other medium to a solid surface.

To mix 3 gallons of pink paint we must take into account the following information:

1 gallon of pink paint is equal to 3 parts red paint and 1 part white paint.

To find out how many parts we need to prepare 3 gallons of pink paint we must multiply the mix values for a gallon by 3.

Red paint:

3 x 3 = 9

White paint:

1 x 3 = 3

Therefore, we need to use 3 parts white paint and 9 parts red paint to make 3 gallons of pink paint.

K'(-2, 1) is the coordinate of the image of point K, found by multiplying the original x-coordinate of the point K (2) by -1. To reflect the triangle over the y-axis, the x-coordinate of each point is multiplied by -1.

Triangle is a three-sided geometric shape which has three angles and three sides. The three sides of a triangle are typically referred to as the base, the height, and the hypotenuse. A triangle can be classified as either right, obtuse, or acute depending on the measure of its angles. Right triangles have one right angle, obtuse triangles have one obtuse angle, and acute triangles have three acute angles.

The coordinate of the image of point K is K’(-2, 1). This means that the x-coordinate of the point is -2 and the y-coordinate of the point is 1. This can be found by multiplying the original x-coordinate of the point K (2) by -1. The y-coordinate of point K remains the same, so the y-coordinate of the image of point K is 1.

Therefore, the coordinate of the image of point K is K’(-2, 1).

If the wax cost $1.38 a square foot, the cost of wax to cover the area of the floor is $1,569.75.

The correct option is B.

The total area of the floor is calculated from the shape of the floor.

The floor is made up of a trapezoid and a rectangle.

The area of a trapezoid can be calculated as:

A = (a + b)/2 * h

where

a and b are the lengths of the bases and h is the height.

The trapezoid has a height of 15 feet and bases of 35 feet and (20 - 20) or 10 feet. So its area is:

A = (35 + 10)/2 * 15

A = 337.5 square feet

The rectangle has a base of 20 feet and a height of 40 feet. So its area is:

A =20 * 40

A = 800 square feet

The total area of the figure is the sum of the areas of the trapezoid and triangle:

A = 337.5 + 800

A = 1137.5 square feet

Finally, to find the cost of the wax, we multiply the area by the cost per square foot:

Cost = 1137.5 * $1.38

Cost  = $1569.75

The equation of the line is y = ( 1/2 )x + 1 and the y intercept is b = 1

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P ( 0 , 1 )

Let the second point be Q ( 4 , 3 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 3 - 1 ) / ( 4 - 0 )

Slope m = 2/4

Slope m = 1/2

Now , the equation of line is y - y₁ = m ( x - x₁ )

The exponentiation rule for raising a power to another power (a^b)^c = a^{bc} therefore a power to a power is equal to the powers multiplied together.  so if the base is equal to (32/5) and the power is -2x. some number raised to the x is equal to (32/5)^-2x therefore because -2^x is equal to -2x the answer is B which is the original base (32/5) with the exponent -2 when raised to the x will be equal to (32/5)^-2x.

Therefore, B is the answer

Answer:

Let x be the measure of the smaller angle. Then the measure of the larger angle is 3x - 12.

We can write this as an equation:

larger angle = 3 * smaller angle - 12 or 3x - 12 = larger angle.

Alternatively, we can write it as:

smaller angle + larger angle = 180 (since they form a straight line)

Substituting larger angle with 3x - 12, we get:

x + 3x - 12 = 180

Simplifying:

4x - 12 = 180

4x = 192

x = 48

Therefore, the measure of the smaller angle is 48 degrees, and the measure of the larger angle is 3(48) - 12 = 132 degrees.

The measure of the larger angle is 12 less than 3 times the measure of the smaller angle x = 48

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’ meaning “corner.”

Angles can mean is an acute angle.

Let smaller angle = x

Larger angle = 3x - 12

x & (3x - 12) are supplementary

So, x + 3x - 12 = 180°

4x - 12 = 180

4x = 180 +12

4x = 192

x = 192/4

⇒ x = 48°

Hence, the measure of the larger angle is 12 less than 3 times the measure of the smaller angle x = 48

The steps for subtracting mixed numbers are the transformation of improper fractions, subtraction of denominator, then subtracting numerator, making it the smallest term, and reverse.

Finding the difference between two mixed numbers is required when subtracting mixed numbers. The steps for subtracting mixed numbers are as follows:

Step 1: Transform the mixed values into improper fractions in step 1. To achieve this, divide the total by the denominator, then add the numerator. The new numerator is the outcome, and it is positioned above the denominator.

Step 2: Identify a common denominator in step two. You must identify a common denominator to subtract fractions with various numerators.

Step 3: Subtract the fractions in step three. Subtract the numerators from the fractions while maintaining the same denominator.

Step 4: Make the outcome simpler. Simplify the outcome if you can by breaking the fraction down into its smallest terms. 13/4 in this instance may be expressed as 3 1/4.

Step 5: Reverse the incorrect fraction to a mixed number in step 5. Divide the numerator by the denominator to return the improper fraction to a mixed number. The full number serves as the numerator, and the remainder serves as the quotient.

Right circular cylinder is the cylinder in which the line joining center of top circle of the cylinder to the center of the base circle of the cylinder is perpendicular to the surface of its base, and to the top.

We are given that;

Diameter of pillar= 10cm

Volume = 12,042 cubic centimeters

Now,

First, we need to find the radius of the pillar. The diameter of the pillar is given as 10 centimeters, so the radius is half of that:

r = 10/2 = 5 centimeters

Now we can substitute the given volume and radius into the formula and solve for the height:

12,042 = π(5)^2h

Divide both sides by π(5)^2:

h = 12,042 / (π(5)^2)
