What is a linear expression?

The linear expression can be defined as the relation between two variables, if we plot the graph of the linear expression we will get a straight line.

If in the linear expression, one variable is present, then the expression is known as the linear expression in one variable.

It is given that:

The relationship between F and C is:

F = (9/5)C + 32

To convert temperature from degrees Celsius to degrees Fahrenheit for c:

Make the subject as C:

(9/5)C = F - 32

As we know,

The expression can be defined as the combination of constants and variables with mathematical operators.

9C = 5(F - 32)

C = 5(F - 32)/9

Thus, the expression in terms of F is C = 5(F - 32)/9 if the relationship between F and C is F = (9/5)C + 32.

a box of cereal states that there are 96 calories in a 3/4-cup serving. what is the unit rate of calories per cup? how many calories are there in 3 cups of ceral

Answers

Going the basic algebra route:

Let x = unit rate for calories per cup,

Then (3/4)*x = 84

and x = 84*(4/3) = 112 calories per cup

The number of calories is there in 3 cups of cereal will be equal to 384.

What are arithmetic operations?

The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.

They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.

As per the given information in the question,

Total calories in 3/4 cup = 96

Let's assume that the number of calories per cup is x.

Then,

3/4 cup = 96

1 cup = x

Use cross-multiplication,

0.75x = 96

x = 96/0.75

x = 128 calories

Then, the calories in 3 cups will be,

= 128 × 3

= 384

Any quadrilateral which can be inscribed in a circle, is called a cyclic quadrilateral.


The main theorem about these quadrilaterals is the following:

In any cyclic quadrilateral, the sum of the measures of the opposite angles is 180°.

This means, m(∠S)+m(∠Q) =180°, 

thus 

(7x-2)+(5x+14)=180

12x+12=180

12x=168

x=168/12=14

Thus the measures of angles Q and S are respectively:

7x-2 = 7*14-2=96 (degrees) and 

5x+14=5*14+14=6*14=84 (degrees)

Every 2/3 hour, Harris can sew 1/6 pair of jeans. What is Harris's rate in pairs of jeans per hour? Drag and drop the correct value into the box.

Answers

Divide the number of pairs of jeans by the time.

(1/6)/(2/3) = 1/6 * 3/2 = 3/12 = 1/4

He can sew 1/4 pair of jeans per hour.

The rate in pairs of jeans per hour is 1/4

For every 2/3 hour Harris can sow 1/6 pair of jeans

Therefore the rate of Harris's jeans in pairs can be calculated as follows

= 1/6 ÷ 2/3

= 1/6 × 3/2

= 3/12

= 1/4

Hence the rate in pairs of jeans per hour is 1/4

Molly bought a pair of gloves and a skirt. The gloves cost £4. She sold teh gloves and the skirt for a total of £48. She made 100% profit on the cost of the gloves. 20% profit on the total cost. Work out the percentage profit on the cost of the skirt

Answers

A) Sale value = 48

Profit on the total cost = 20% = 0.20

=> Total cost + 0.20 total cost = Sale value

=> 1.20 total cost = 48

=> total cost = 48 / 1.20

=> total cost = 40

B) Cost of the gloves = 4

=> Cost of the skirt = total cost - cost of the gloves

=> Cost of the skirt = 40 - 4 = 36

C) Price of the skirt = total value - price of the gloves

Total value = 48

Price of the gloves = cost of the gloves + margin

margin of the gloves = 100% on the cost = cost

Price of the gloves = cost of the gloves * 2

Price of the gloves = 4 * 2 = 8

=> Price of the skirt = 48 - 8 = 40

D) Profit on the skirt = price of the skirt / cost of the skirt = 40 / 36 = 1.1111

Profit % = 11,11 %



Final answer:

The profit-maximizing quantity for Doggies Paradise Inc. is determined by comparing marginal revenue and marginal cost for each output level and is found to be at five units, which results in a profit of $40.

Explanation:Profit Maximization Calculation

To calculate the profit-maximizing quantity for Doggies Paradise Inc., we construct a table showing total revenue, marginal revenue, total cost, and marginal cost for each output level from one to five units. Given the price of $72 per dog coat, the fixed costs of $100, and the various total variable costs for each output level, we can determine the profit-maximizing quantity by comparing marginal revenue and marginal cost.

Calculate total revenue by multiplying the number of units by the price ($72).Calculate total cost by adding fixed costs ($100) to the total variable costs for each output level.Determine marginal revenue and marginal cost for each additional unit produced.Identify the output level where marginal revenue equals marginal cost; this is the profit-maximizing quantity.Subtract total cost from total revenue to find profits at this output level.

If Doggies Paradise Inc. produces and sells five units, they will achieve a profit of $40, as total revenue will be higher than total costs, indicating that the fifth unit is adding to the profits.

Consider a civilization broadcasting a signal with a power of 2.0×104 watts. The Arecibo radio telescope, which is about 300 meters in diameter, could detect this signal if it is coming from as far away as 141 light-years. Suppose instead that the signal is being broadcast from the other side of the Milky Way Galaxy, about 70000 light-years away.

Answers

For light: Inverse Square Law 


The signal is weaken by the inverse square of the difference of distances this means that one over the square of the difference. 


Therefore, 70000LY / 141 LY =496.45 and that squared =246462.602 times less signal, or 1/246462.602.


 2 For a circular telescope like the Arecibo radio telescope that equals Pi times the radius squared. Sensitivity of the telescope depends on its area.
The new telescope needs 246462.60 times that area to have enough sensitivity 


(150 x 150 x Pi) = 70 685 sq m area for the Arecibo telescope and that times 246462.60
= 1.74212 x 10^10


What is the diameter of a circle with that area?

 
1. Divide the area by Pi = 5.548156 x 10^9
2. Take the square root of the result to find the radius = 74485.94293

Jacob has 16 toy cars.3/8 of the cars are red and the rest are blue.how many cars are blue

Answers

5/8 (10) of the cats are blue.

Answer:

The number of blue toy cars that Jacob has is 10.

Solution:

Given:

Total number of toy cars = 16

Number of red cars = [tex]\frac{3}{8}[/tex] of the total number of cars = [tex]\frac{3}{8}\times16[/tex]

On dividing 8 and 16 we get 2 i.e. [tex]3\times2=6[/tex]

[tex]\therefore[/tex] Total red cars = 6

To find: the number of blue toy cars

Number of blue toy cars = Total number of toy cars - Number of red cars

[tex]\Rightarrow 16-6=10[/tex]

Hence, blue cars = 10

The volume of a cube depends on the length of its sides. This can be written in function notation as v(s). What is the best interpretation of v(3) = 27?

Answers

The volume of a cube formula is v(s)=s^3. If you plug in 3 for s, you will find that v(s) would in fact equal 27. Thus the length of the sides are 3 and the volume is 27.

Answer:

Step-by-step explanation:

The volume of the cube depends on the length of its sides.

Volume can be represented by the function

V(s) = s³

Where s represents the length of one side.

Now V(3) = 27

or V(3) = 3³   will represent the volume of the cube with a side of length 3 unit.

The one with a dilation

Answer:  A) Triangle MNO is reflected across the y-axis and then dilated by a scale factor of 1.8 to form triangle M"N"O".

Step-by-step explanation:

We know that we prefer rigid motions to create congruent images.

There are four kinds of rigid motions:  

1) translation 2) reflection 3) rotation 4) glide reflection.

But a dilation is a transformation that creates an image having similar shape as the original, but with a different size.

So it does not create congruent images.

Hence transformations will produce similar, but not congruent, figures is :
