1 and 1/2 divided by 4 and 2/8

Answer:

3.14 cm²

Step-by-step explanation:

The formula to find the area of a circle is:

A = πr²

Here,

r ⇒ radius ⇒ 1 cm

Let us find it now.

A = πr²

A = 3.14 × 1 × 1

A = 3.14 cm²

Answer:

45/49

Step-by-step explanation:

The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.

9/14 * 10/7 = 90/98

divide the numerator and the denominator by 2.

90 * 2 = 45

98 * 2 = 49

45/49

The equation for the proportion, p, of consumers who shop with coupons is: p = C/N where C is the number of consumers who use coupons and N is the total number of consumers asked.

An equation is a mathematical statement that indicates the equality of two expressions. It consists of two expressions separated by an equal sign (=). The expression on the left side of the equal sign is equivalent to the expression on the right side. Equations can have one or more variables, which are usually represented by letters such as x, y, or z. The goal in solving an equation is to determine the value(s) of the variable(s) that make the equation true. This involves manipulating the expressions on both sides of the equal sign using algebraic operations such as addition, subtraction, multiplication, and division, to isolate the variable on one side of the equation. Equations are used in many areas of mathematics and science to represent relationships between variables and to solve problems. They are also used in various fields such as engineering, physics, and economics to model real-world situations and make predictions based on mathematical analysis.

Here,

This equation represents the ratio of the number of consumers who use coupons to the total number of consumers. It is commonly used in statistics and market research to measure the prevalence of a certain behavior or preference among a population. By calculating the proportion of consumers who use coupons, businesses can make informed decisions about their pricing strategies, promotions, and advertising campaigns.

I used a calculator

Answer:

The selling price of the diamond necklace at Shamin Jewelers after 10% discount is:

$442 * 0.9 = $397.80

The selling price of the same necklace at the competitor's store after 34% and 14% discount is:

$527 * 0.66 * 0.86 = $247.08

So, Shamin Jewelers needs to offer an additional discount to meet the competitor's price:

$397.80 - $247.08 = $150.72

To calculate the additional rate of discount, we divide the difference by the original selling price at Shamin Jewelers and multiply by 100:

($150.72 / $442) * 100 = 34.11%

Therefore, Shamin Jewelers must offer an additional 34.11% discount to meet the competitor's price.

The calculated IQR of the list of numbers is 3

From the question, we have the following parameters that can be used in our computation:

1, 2, 4, 3, 3, 8, 5, 6

Sort the above number in ascending order

So, we have

1, 2, 3, 3, 4, 5, 6, 8

Split the above numbers to 2

So, we have

1, 2, 3, 3

4, 5, 6, 8

In the above, we have

Q1 = (2 + 3)/2 = 2.5

Q3 = (5 + 6)/2 = 5.5

using the above as a guide, we have the following:

IQR = 5.5 - 2.5

The angle which is complementary to ∠BFC in the given figure is ∠CFD.

When two angles' measurements add up to 90 degrees, they are said to be complimentary. When two angles' measures sum up to 180 degrees, they are said to be supplementary.

Given:

The angle EFD is a right-angle triangle,

Here, the sum of ∠ BFD and ∠EFD is 180°  (Supplementary angle),

∠ BFD + ∠EFD = 180

∠ BFD = 180 - 90

∠ BFD = 90°

The angle BFD is also a right angle triangle if  EFD is a right angle triangle,

For complementary angle,

∠ BFC + ∠ CFD = 90°

Thus,  ∠ CFD is complimentary to ∠ BFC

The number of pounds of strawberries sold and the number of pounds of grapes sold is 32 and 20 respectively.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given that the selling price of strawberries each pound = $2.50,

The selling price of grapes each pound = $2

The total earning = $160

Let x is the no of a pound of strawberries and y is the no of a pound of grapes sold, then equation will be,

x = y + 12 and 2.50x + 2y= 160

Solve the equation by substitution method;

x = 32 and  y = 20

Therefore, the number of pounds of strawberries sold is 32

the number of pounds of grapes sold is 20.

Answer:

In mathematics, the extrema of a function refer to the maximum and minimum values that the function can take on. These values can be local extrema, which occur within a certain range of the function, or global extrema, which are the maximum and minimum values over the entire domain of the function.

To find the extrema of a function, one can use a variety of techniques, such as taking the derivative of the function and setting it equal to zero to find the points of stationary values, or using the second derivative test to determine whether a stationary point is a local maximum or minimum.

Interpreting the extrema of a function can provide valuable information about the behavior of the function. For example, the global maximum of a function might represent the highest possible value that the function can attain, while the global minimum might represent the lowest possible value. Local extrema can also be important, as they can indicate changes in the slope or concavity of the function, which can have important implications for applications such as optimization or modeling real-world phenomena.

The length of the fencing is 62.4 feet.

The width of the fencing is 17.6 feet.

Given,

The measurement of the Christmas garland = 160 feet

The width of the fencing = w

The length of the fencing, l = 4w - 8

We have to find the length and width of the fencing.

Here,

Perimeter can be taken as 160. Because garland will cover the entire fencing.

Perimeter = 2(l + w)

160 = 2(4w - 8 + w)

160 = 2(5w - 8)

160/2 = 5w - 8

80 + 8 = 5w

88/5 = w

width = 17.6 feet

Now,

l = 4w - 8

l = 4 × 17.6 - 8

l = 70.4 - 8

length = 62.4 feet

That is,

The length of the fencing is 62.4 feet.

The width of the fencing is 17.6 feet.

Answer:

Total cost= $5,425

Step-by-step explanation:

Giving the following information:

Month Machine _Hours Amount

January 200 $2,800

February 350 3,000

March 450 4,000

April 500 5,000

May 600 5,200

June 580 5,800

First, we need to calculate the fixed and variable costs. To do it, we will use the high-low method:

Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)

Variable cost per unit= (5,800 - 2,800) / (600 - 200)

Variable cost per unit= $7.5 per hour

Fixed costs= Highest activity cost - (Variable cost per unit * HAU)

Fixed costs= 5,800 - (7.5*600)

Fixed costs= $1,300

Fixed costs= LAC - (Variable cost per unit* LAU)

Fixed costs= 2,800 - (7.5*200)

Fixed costs= $1,300

Now, we can determine the total cost for 550 hours:

Total cost= 1,300 + 7.5*550

Total cost= $5,425
