Three equivalent fractions for 30/48

The result is the mean of 3.9 miles and median of the team's distances is 3.5 miles.

Mean and median are two ways to measure the center of a set of numbers. Mean is the average of all the numbers in the set, while median is the middle number in the set. Mean is more affected by extreme values, while median is not. Mean is generally used when data is normal, and median when data is skewed.

Mean and median are both measures of central tendency, or measures of the center of a data set. Both measures are used to summarize a data set, but the mean is more affected by outliers, or extreme values, while the median is not.

The mean of the team's distances is 3.9 miles, and the median is 3.5 miles. To calculate the mean, add all the distances together (3.5 + 2.5 + 4 + 3.25 + 3 + 4 + 6) and divide by the number of distances (7). The result is the mean of 3.9 miles. To calculate the median, first order the distances from least to greatest (2.5, 3, 3.25, 3.5, 4, 4, 6) and take the middle number (3.5). The median of the team's distances is 3.5 miles.

The answer is y=x+4

You would had the 4 to the side with the x on it.

Answer:

Below

Step-by-step explanation:

Slope-intercept form is  :    y = mx + b

y - 4 = x       add 4 to each side of the equation

y = x + 4      Done.

The solution set for the absolute value equation |2x-4|=20 is {-14, 14}.

An absolute value equation is one that contains an absolute value expression, such as ||x| - 1| = 2.

These types of equations are solved by breaking them down into two separate equations and solving each one separately:

one with the original absolute value expression and a positive value for the other side, and the other with the negated absolute value expression and a negative value for the other side.

The steps to solving an absolute value equation are as follows:

1. Write the equation in the form |expression| = value, where expression is the absolute value expression and value is the constant on the right-hand side.

2. Separate the equation into two equations: expression = value and expression = -value.

3. Solve each equation for the variable.

4. Check the solution(s) to ensure that they satisfy the original equation.

Answer:

  £67.78

Step-by-step explanation:

Given that rolls come in a package of 20 for £2.87 and ham slices come in a package of 30 for £6.32, you want the minimum cost of enough packs for more than 90 sandwiches, each of which uses 1 roll and 2 ham slices.

One package of 20 bread rolls is enough for 20 sandwiches. One package of 30 ham slices is enough for 15 sandwiches. The least common multiple of these numbers is the number of sandwiches that will use a whole number of each of the kinds of packages:

  LCM(20, 15) = 60 = 3·20 = 4·15

We want to make a number of sandwiches that is more than 90. The least multiple of 60 that is more than 90 is 120.

120 sandwiches will require 120/20 = 6 packages of bread rolls, and 120/15 = 8 packages of ham slices.

The cost of 6 packages of bread rolls and 8 packages of ham slices is ...

  6×£2.87 +8×£6.32 = £17.22 +50.56 = £67.78

The least Tina can spend on packs of bread and ham is £67.78.

In the given figure by using the alternative angles rule we know that x = 82°.

Alternate angles are a unique type of angle in geometry.

The collection of non-adjacent angles on either side of the transversal is known as alternate angles.

Alternative Interior Angles: Angles are created on the inside, or interior, of two other lines when a third line known as the transversal crosses them. These other lines are typically parallel.

The alternate internal angles are those that are perpendicular to one another.

So, in the given figure:

∠ABD = ∠BDC = 35° (Alternate angles)

Then, ∠DBC will be:

82 + 35 + x = 180

117 + x = 180

x = 180 - 117

x = 63°

Then, ∠DBC = ∠BDA = 63° (Alternate angles)

Now, ∠DAB = 63 + 35 + x = 180

= 63 + 35 + x = 180

= 98 + x = 180

= x = 180 - 98

= x = 82°

Therefore, in the given figure by using the alternative angles rule we know that x = 82°.

Answer: To find the coordinates of D1.5(ABCD), we need to perform a dilation with center D and scale factor 1.5 on the coordinates of each point.

The coordinates of point D are (-5, -10). To dilate point A, we can subtract the coordinates of D from the coordinates of A, multiply by 1.5, and then add the coordinates of D back:

D1.5(A) = 1.5[(2, 0) - (-5, -10)] + (-5, -10) = 1.5(7, 10) + (-5, -10) = (6.5, 5)

Similarly, we can dilate points B and C:

D1.5(B) = 1.5[(8, -4) - (-5, -10)] + (-5, -10) = 1.5(13, 6) + (-5, -10) = (14.5, -4)

D1.5(C) = 1.5[(4, -6) - (-5, -10)] + (-5, -10) = 1.5(9, 4) + (-5, -10) = (7.5, 4)

Therefore, the coordinates of D1.5(ABCD) are A'(6.5, 5), B'(14.5, -4), C'(7.5, 4), and D(-5, -10).

The true statement about the polynomials is (b) No, it's only with polynomials with a degrees of 1

Given that the polynomials f and g have a degree of 3

The composition of two functions, f ∘ g (read as "f composed with g"), is not commutative in general, meaning that f ∘ g is not necessarily equal to g ∘ f.

This holds true for polynomials of degree 3 as well.

In fact, if f and g are two different polynomials of degree 3, then f ∘ g and g ∘ f will be different polynomials in general.

The equation f ∘ g = g ∘ f holds true is when f and g are constant polynomials, that is, polynomials of degree 0 or 1.

The ratio used to depict the relationship between the dimensions of a model or scaled figure and the corresponding dimensions of the real figure or object is called the scale. On the other hand, a scale factor is a value that is used to multiply all of an object's parts in order to produce an expanded or decreased figure.

Given, A road map is drawn to a scale of 1mm: 50m

i) To find the distance on the map which represents 20 km on the road, we need to use the scale of the map.

Since 1 mm on the map represents 50 m on the road, we can set up a proportion:

1 mm / 50 m = x mm / 20,000 m

Cross-multiplying and solving for x, we get:

x = (1 mm / 50 m) * 20,000 m = 400 mm

Therefore, the distance on the map which represents 20 km on the road is 400 mm.

ii) To find the distance on the road which corresponds to 228 on the map, we can again use the scale of the map.

Since 1 mm on the map represents 50 m on the road, we can set up a proportion:

1 mm / 50 m = 228 mm / x m

Cross-multiplying and solving for x, we get:

x = (228 mm / 1) / (50 m / 1) = 4.56 km

Therefore, the distance on the road which corresponds to 228 on the map is 4.56 km.

Alex will need 150 tiles to make his mosaic.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the tiles in a two-dimensional plane is called the area of the tiles.

To determine the number of tiles needed to create the mosaic, we need to find out the area of the wall mosaic and then divide it by the area of each tile.

First, let's find the area of the wall mosaic. We can do this by counting the number of squares within the rectangular shape, which is the plan for the mosaic.

By counting, we can see that there are 30 squares in the horizontal direction and 20 squares in the vertical direction. Therefore, the area of the wall mosaic is:

Area of wall mosaic = 30 x 20 = 600 square cm

Now, let's find the area of each tile. The problem tells us that each tile is a square with a side length of 2 cm. Therefore, the area of each tile is:

Area of each tile = 2 x 2 = 4 square cm

Finally, we can find the number of tiles needed by dividing the area of the wall mosaic by the area of each tile:

Number of tiles needed = Area of wall mosaic ÷ Area of each tile

= 600 ÷ 4

= 150

Therefore, Alex will need 150 tiles to make his mosaic.

(a) The number of cans of spray paint that needs to be purchased is 3.

(b) The cost to paint the wooden prism is $12.00.

To determine the cost of painting the wooden prism, we need to calculate the surface area of the prism and then divide it by the coverage of each can of spray paint.

Let's assume the wooden prism has dimensions of 6 feet by 4 feet by 3 feet.

Part A:

The surface area of the prism can be calculated as follows:

The top and bottom faces have an area of 6 ft x 4 ft = 24 ft² each

The two side faces have an area of 6 ft x 3 ft = 18 ft² each

The front and back faces have an area of 4 ft x 3 ft = 12 ft² each

Therefore, the total surface area of the prism is:

2(24 ft²) + 2(18 ft²) + 2(12 ft²) = 96 ft²

Since each can of spray paint covers 40 ft², we need:

96 ft² ÷ 40 ft²/can = 2.4 cans

We can't purchase a partial can of spray paint, so we need to round up to the nearest whole can.

Therefore, we need to purchase 3 cans of spray paint.

Consider the expression |x+3|5x-2|-(x+3)(4x+3)|. To rewrite this expression in the form (x+3)|ax+b|, we will need to use the distributive property and combine like terms.

First, let's distribute the (x+3) term:

|x+3|5x-2| - (x+3)(4x+3) = |5x^2 + 13x - 2| - |4x^2 + 15x + 9|

Next, let's combine like terms:

|5x^2 + 13x - 2| - |4x^2 + 15x + 9| = |x^2 - 2x - 11|

Now, we can factor the expression inside the absolute value:

|x^2 - 2x - 11| = |(x+3)(x-5)|

Finally, we can rewrite the expression in the form (x+3)|ax+b|:
