A grocery store sells crackers in three box sizes. Which size box is the best buy? 8 oz for $2.00 12 oz for $2.64 16 oz for $3.20

A B) hexagon is the shape with 6 sides.

A hexagon is a polygon with six straight sides and six angles. In geometry, hexagons are commonly used in various designs and structures due to their symmetry and stability.

Regular polygon refers to a polygon with equal sides and equal angles, such as a hexagon. Hexagons have the property of being equilateral and equiangular, making them regular polygons.

Six Electron Groups form an octahedron, which is a polyhedron made up of identical equilateral triangles and has six identical vertices, showcasing the connection between the number six and geometric shapes.

Therefore, option B is correct.

Answer:

The correct option is C.

Step-by-step explanation:

The given table represent the number of contestants in each round of the competition.

The average rate of change of f(x) from x = 3 to x = 5.

[tex]m=\frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]

[tex]m=\frac{f(5)-f(3)}{5-3}[/tex]

[tex]m=\frac{4-16}{2}[/tex]

[tex]m=\frac{-12}{2}[/tex]

[tex]m=-6[/tex]

The average rate of change of f(x) from x = 3 to x = 5 is -6, it represents the average rate at which the number of contestants decreased from the third round to the fifth round.

Therefore option C is correct.

round miles up to 84

round gallons down to 2

 and divide

84 /2 = 42 miles per gallon ( estimate)

Step-by-step explanation:

Let r₁ be the rate of filling of small pipe, r₂ be the rate of filling of large pipe  and V be the volume of swimming pool.

[tex]\texttt{Rate of small pipe},r_1=\frac{V}{t_1}\\\\\texttt{Rate of large pipe},r_2=\frac{V}{t_2}=\frac{V}{0.5t_1}=2r_1[/tex]

If both pipes are combined it takes 213 hours, that is

              [tex]t=\frac{V}{r_1+r_2}\\\\213=\frac{V}{r_1+2r_1}\\\\V=639r_1[/tex]

Now we need to find how much time it takes to fill the pool by large pipe,

That is

               [tex]t_2=\frac{V}{r_2}=\frac{639r_1}{2r_1}=319.5hours[/tex]

By large pipe only it will take 319.5 hours to fill the pool.          

1. The measure of angle A is [tex]\(22^\circ\).[/tex]

2. The measure of angle B is[tex]\(68^\circ\).[/tex]

To find the measures of angles A and B, we can use the fact that they are complementary, meaning their measures add up to[tex]\(90^\circ\).[/tex]Let's set up an equation using the given information:

[m_A + m_B = 90]

Given that[tex]\(m_A = 3x - 8\)[/tex]and (m_B = 5x + 10), substitute these expressions into the equation:

3x - 8 + 5x + 10 = 9

Combine like terms:

8x + 2 = 90

Subtract 2 from both sides:

8x = 88

Divide by 8:

x = 11

Now that we know the value of (x), we can find the measures of angles A and B:

[tex]\[m_A = 3x - 8 = 3(11) - 8 = 33 - 8 = 25\][/tex]

[tex]\[m_B = 5x + 10 = 5(11) + 10 = 55 + 10 = 65\][/tex]

Therefore, the measure of angle A is \(25^\circ\) and the measure of angle B is [tex]\(65^\circ\).[/tex] To check, we can verify that these angles are indeed complementary:

25 + 65 = 90

So, angles A and B satisfy the condition of being complementary.

Answer:

Collinear, coplanar, and between the points

Step-by-step explanation:

Collinear means that the points are in the same line.

Coplanar means that the points are in the same plane.

Between the points is used when three points are in the same line an you want tro express that one of them is between the others.

So those three relationships can apply for the three points.

noncollinear not apply because it means that the points don't lie in a line.

To calculate an increase, multiply the original value by the percentage increase. For simple interest, use the formula Interest = Principal * Rate * Time. Percentage increase in mass can be found with the formula: [(Final mass - Initial mass) / Initial mass] * 100%. These methods result in a new train fare of £24.21, a bank balance after 5 years of £472, and a 25% increase in the puppy's mass.

1. To work out the new fare, we first need to calculate how much the fare has increased by. 2.8% of £23.55 is found by multiplying 23.55 by 0.028, which comes out to £0.66 (rounded to the nearest penny). Adding this increase to the original fare gives us a new fare of £24.21.

2. The simple interest can be calculated using the formula Interest = Principal * Rate * Time. In this case, Heidi's investment of £400 (the principal) is earning 3.6% (the rate) in interest every year for 5 years (the time). So, the interest Heidi earns equals £400 * 3.6% * 5 = £72. Adding this to the original amount gives us £472.

3. The percentage increase in the puppy's mass is calculated as follows: [(2.25 kg - 1.8 kg) / 1.8 kg] * 100%. So, the mass has increased by 25%.

It would take 3.625 gallons of gasoline to fill a 14.5-gallon tank that is already 3/4 full.

The question asks how many gallons of gasoline are needed to fill a 14.5-gallon tank that is already 3/4 full. To find the amount needed to fill the tank, we first determine how much gasoline is currently in the tank by multiplying 14.5 gallons by 3/4:

14.5 gallons × 3/4 = 10.875 gallons

This means that there are 10.875 gallons of gasoline in the tank at the moment. To find out how much more gasoline is needed to fill the tank, we subtract this amount from the tank's total capacity:

14.5 gallons - 10.875 gallons = 3.625 gallons

Therefore, it would take 3.625 gallons of gasoline to fill the tank.

"The correct expression to show the total number of empty spaces in the bike racks is [tex]\( 4 \times 15 - 16 \).[/tex]

To arrive at this expression, we start by calculating the total capacity of all the bike racks combined. Since there are 4 bike racks and each can hold 15 bikes, the total capacity is [tex]\( 4 \times 15 \).[/tex] This gives us the maximum number of bikes that can be parked in all the racks.

Next, we subtract the number of bikes that are currently parked in the racks from the total capacity. There are 16 bikes parked. Therefore, the expression to find the number of empty spaces is:

[tex]\[ \text{Total capacity} - \text{Number of bikes parked} \][/tex]

Substituting the given numbers into the expression, we get:

[tex]\[ 4 \times 15 - 16 \][/tex]

This expression represents the total number of empty spaces in the bike racks. When evaluated, it will give us the number of spaces available for additional bikes to be parked."
