The equation that shows 3 less than the product of 4 and m is 3 < 4m

Formation of equation is a means of transforming statements into equations

The product of 4 and m is 4m

If 3 is less than the product of 4 and m, this is expressed as:

3 < 4m

Divide both sides by 4

3/4 < m

m > 3/4

Hence the equation that shows 3 less than the product of 4 and m is 3 < 4m

The Arithmetic Mean and Median of the given set of data ( 2, 5, 13, 15, 19, 21 ) are 12.5 and 14 respectively.

Arithmetic mean is simply the average of a given set numbers. It is determined by dividing the sum of a given set number by their number of appearance.

Mean = Sum total of the number ÷ n

Where n is number of numbers

Median is the middle number in the data set.

Given the sets;

Mean = Sum total of the number ÷ n

Mean = (2 + 5 + 13 + 15 + 19 + 21) ÷ 6

Mean = 75 ÷ 6

Mean = 12.5

Median is the middle number in the data set.

Median = ( 13 + 15 ) ÷ 2

Median = 14

Therefore, the Arithmetic Mean and Median of the given set of data ( 2, 5, 13, 15, 19, 21 ) are 12.5 and 14 respectively.

Answer:

25/8 = 3.125

Step-by-step explanation:

Answer:

5 × 5 ÷ 8 = 3 ¹/₈

Step-by-step explanation:

Using the order of operations we need to work from left to right.

Therefore we should carry out the multiplication first.

5 × 5 means "5 lots of 5"

⇒ 5 × 5 = 5 + 5 + 5 + 5 + 5 = 25

Now we need to divide 25 by 8.

8 + 8 + 8 = 24

Therefore, 8 goes into 25 three times with a remainder of 1.

So,  5 × 5 ÷ 8 = 3 ¹/₈

To get a probability of 3/5, 16 red marbles must be added.

There are 8 red, 9 yellow, and 7 green marbles, for a total of:

8 + 9 + 7 = 24.

The probability of getting a particular color of marble is given by the quotient between the number of marbles of that color and the total number of marbles.

Here, we want to get a probability of drawing a red marble equal to 3/5.

So, if we add x red marbles, the probability of getting a red marble will be:

P = (8 + x)/(24 + x)

And that must be equal ot 1/5, then we write:

(3/5) = (8 + x)/(24 + x)

If we multiply both sides bt (24 + x), we will get:

3*(24 + x)/5 = 8 + x

Now we can solve that for x.

3*24/5 - 8 = x - x(3/5) = (2/5)*x

x = (3*24/5)*(5/2) - (5/2)*8 = 16

So 16 red marbles must be added, the correct option is b.

Answer:

120+5x+15+5x+15=180

10x=180-120-15-15

x=30°

Answer: 9^o

Step-by-step explanation:

(all angles in an isoceles triangle adds up to 180 degrees)
5 x + 15 + 120 = 180
5x  = 180 - 120 - 15
5 x = 45

   x = 9^o

Answer:2863.6ft

Step-by-step explanation: x=100/tan2 makes the awnser.

By the combined area of the triangles and the base. The total surface area of the regular pyramid would be 197.1 ft^2.

The area of the triangle is defined as the product of half the base and the height of the triangle.

The area of the triangle = 1/2 x b x h

we need to find the areas of each triangle in the pyramid.

The area of base = 15.6

The area of each outer triangle = 1/2 x 9 x 12

 = 54

There are 3 triangle

3 x 54 = 162

The total area will become

162 + 35.1

= 197.1

Therefore, The total surface area of the regular pyramid = 197.1 ft^2

If the 35 teaspoons of blue paint are there. Then for the purple paint, we need to add 42 teaspoons of red paint.

A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A percentage is a mathematical expression in which two things are equal.

A mixture of purple paint contains 6 teaspoons of red paint and 5 teaspoons of blue paint.

The dimension of the rectangular model shows that the length is 9 inches and the width is 8 inches

The area of a rectangle is the multiplication of the length and the width of the rectangle.

The area of the rectangle is expressed as:

Area (A) = length (L) × width (w)

A = l × w

Given that:

72 = (2x - 7) × (x)

72 = 2x² - 7x

2x² - 7x - 72 = 0

Using the quadratic calculator

x = 8 or x = -9/2

Step-by-step explanation:

We know that the surface area is the sum of the area of the prism's faces.

It should be noted that the area of any face is equal to the area of its opposite face. Thus, we get the following equation for the surface area:
