you want to buy some beans . a 6 - ounce package costs $2.16 . a 15 - ounce package costs $5.55 . a 26 - ounce package costs $9.10 . which package is the best buy

Answers

Answer:

26-ounce package

Step-by-step explanation:

Divide the cost for a 6-ounce and a 15-ounce package separately by the number of ounces listed above. 1 ounce for a 6-ounce package costs around $0.36 and 1 ounce for a 15-ounce package cost around $0.37. If we put the 26-ounce package in place, then each ounce cost $0.35. We want to buy the one that is the cheapest out of all of them and since the 26-ounce package cost more cheaper than the other packages, then you should buy the 26-ounce package since it is the best deal.

What is the area of the rhombus?

16.75 cm2
33.5 cm2
139.5 cm2
279 cm2

Answers

Answer:279 cm²Step-by-step explanation:

Formula used,

Area of rhombus = Base × height

Substituting the values,

$ \longrightarrow$Area = 18 × 15.5

$ \longrightarrow$ Area = 279 cm²

Therefore, 279 cm² is the area of the rhombus .

Answer:

D) 279 cm²

Step-by-step explanation:

Area of a rhombus formula:
$A=bh$

This formula is also used for squares and rectangles.

So, we can substitute in our values such as:

A=(18)(15.5)

simplify

A=279

Now, add our label and units:

There are 5 blue socks in Josh’s drawer. After he removes 3 non-blue socks, the probability to pick a blue sock at random becomes . How 1/7 many non-blue socks were in Josh’s drawer originally?

Answers

Answer: There is 5 non blue sock in Josh's drawer

Step-by-step explanation:

The denominator shows the total of nonblue and blue socks. So there are 7 non-blue and blue socks in the drawer after he removes 3 non blue socks.To find how many non-blue where in the drawer originally you need to find how many non blue are in the draw after removing the three. So you subtract 7 from 5 which gives you 2. So there are 2 non-blue socks in the drawer after removing the three. Now you need to find how many non-blue were there before he removed the three. So add the 3 non blue socks that he removed to the two that were there after which gives you five.

there are 5 non blue socks

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there

Answers

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

What is the height of a cylinder with a radius of 3 and a volume of 189?

Answers

Answer:

6.68 units (2 d.p.)

Step-by-step explanation:

The formula for the volume of a cylinder is:

$\boxed{V=\pi r^2 h}$

where:

V is the volume.r is the radius of the circular base.h is the height.

Given values:

V = 189 cubic unitsr = 3 units

To find the height of the cylinder, substitute the given values into the formula and solve for h:

$\implies 189=\pi \cdot 3^2 \cdot h$

$\implies 189=9\pi \cdot h$

$\implies \dfrac{189}{9 \pi}=\dfrac{9\pi \cdot h}{9 \pi}$

$\implies \dfrac{189}{9 \pi}=h$

$\implies h=6.6845076...$

Therefore, the height of a cylinder with a radius of 3 units and a volume of 189 cubic units is 6.68 units (2 d.p.).

Answer:

h≈6.68

Step-by-step explanation:

6.68 is the height of a cylinder with a radius of 3 and a volume of 189

By matching the statistical measures with their corresponding values, we have:

Median: 23.5

Mean: 22.5

Mode: 20, 24, 25, 26

Lower Quartile: 21.5

Upper Quartile: 24.5

To match the statistical measures with their corresponding values, we need to analyze the dataset and identify the appropriate measures. Here's the breakdown:

Median: The median is the middle value of the dataset when it is arranged in ascending order. In this case, since we have 12 data points, the middle two values are 23 and 24. Therefore, the median is the average of these two values, which is 23.5.

Mean: The mean is calculated by summing up all the values in the dataset and dividing by the total number of values. Adding up the given values, we get 262. Dividing this sum by 12 (the number of values), we obtain a mean of 22.5.

Mode: The mode represents the value(s) that appear(s) most frequently in the dataset. In this case, the values 20, 24, 25, and 26 all appear twice, making them the modes of the dataset.

Lower Quartile: The lower quartile divides the dataset into four equal parts, with 25% of the data falling below it. To find the lower quartile, we need to locate the value that is greater than or equal to 25% of the data. In this case, the 25th percentile falls between the values 21 and 22. The lower quartile is the average of these two values, which is 21.5.

Upper Quartile: The upper quartile divides the dataset into four equal parts, with 75% of the data falling below it. Similar to the lower quartile, we need to locate the value that is greater than or equal to 75% of the data. In this case, the 75th percentile falls between the values 24 and 25. The upper quartile is the average of these two values, which is 24.5.

Write the system of equations in Slope-Intercept Form from the graph below.

Answers

Answer:

y > -2x +3 . . . . line Ay ≤ x . . . . . . . . line B

Step-by-step explanation:

You want the equations for the inequalities shown on the graph.

Line A

The downward sloping dashed line crosses the y-axis at y=3. It has a "rise" of -2 units for each 1 unit to the right. Its slope is rise/run = -2/1 = -2.

The equation for this boundary line can be written ...

y = -2x +3

The graph is shaded above this line, which is not included in the solution. The inequality graphed is ...

y > -2x +3

Line B

The upward sloping solid line crosses the y-axis at y=0 and has a rise of 1 for each run of 1 unit to the right. Its slope is 1/1 = 1, and its y-intercept is 0.

The equation for the boundary line can be written ...

y = 1x +0

The graph is shaded below the solid boundary line, so the boundary is included in the solution. The inequality graphed is ...

y ≤ x

Answers

Answer:

A. the slope of the line is 40

b. The equation of the line is 40x - y + 600 = 0

c. The equation is g(x) = 4x + 600

The balance is 628 RS

How to find the The slope of the line

Formula = Δy/Δx

= 720 - 600 / 3 - 0

= 120 / 3

= 40

The equation of a line is given as y - y₁ = m(x - x₁)

m = 40 which is the slope.

When we substitute we have

y - 600 = 40(x - 0)

We have to substitute x as 0

y - 600 = 0

y = 600

therefore y = 40x + 600

This implies that 40x - y + 600 = 0

c. y - 600 = 40x

g(x) - 600 = 4x

hence

g(x) = 4x + 600

d. x is 7 days

g(x) = 4*7 + 600

= 628

The balance in the bank after 7 days is 628Rs

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?

Answers

Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

We know that the circumference of a circle is given by:

C = 2πr

where C is the circumference and r is the radius of the circle.

In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:

18 = 2πr

Solving for r, we get:

r = 9/π ≈ 2.864 feet

Now we can use the formula for the area of a circle:

A = πr^2

Substituting the value we found for r, we get:

A = π(2.864 ft)^2 ≈ 25.85 ft^2

Therefore, the approximate area inside the circular park is approximately 25.85 square feet.
