Answer:

11/12

Step-by-step explanation:

5/8 + 3/4 = 1 3/8

-2/3 - 5/6 = 1 1/2

1 3/8 divided by 1 1/2 = 11/12

Answer:

A=3

Step-by-step explanation:

divide both sides by 7

a=3

The cost for 866 miles will be $53.31.

The car car averages 32 mpg and gas costs $1.97 per gallon.

Therefore,. the cost for 866 miles will be:

= 27.0625 × $1.97

= $53.31

The cost is $53.31.

Step-by-step explanation:

The price of one section represent  $2.

We will use the tape diagram to represent the sale price and regular price of the item.

We know that percentage is used to represent the fractions of a whole number.

Here, the regular price is the whole number, and the discount and discounted price represent the fractions.

The coupon she used is 30%, which means 30% off the regular price is the discounted price. We know that 30% + 70% = 100%. This means Mia paid 70% of the regular price for the backpack.

Refer to the attached image for the tape diagram.

By looking at the tape diagram attached, it is clear that 7 sections are used to show the discounted price.

If the discounted price is $14,

The price of one section = $14/7 =  $2

Therefore, the price of one section is $2.

⇒The regular price = 10 × price of one section = 10 × $2 = $20.

So, Peter needs to pay $20 to buy a similar backpack.

The area of the Triangle ABC will be 18 cm²

In the question, It is given that ∠B = 75° and ΔABC is Right angeled at ∠C = 90° and AB = 12CM.

We know that the Area of Δ is defined by : [tex](\frac{1}{2} *b*h)[/tex]

In the picture below, we have base and height BC and AC respectively.

We don't have the values for AC and BC. So to find the values of Base & Height we will use Trigonometric Ratios.

We know Sin(∠) = Perpendicular/Hyoptenuse and,

Tan(∠) = Perpenciular/Base. Putting values into the respective ratios and taking ∠B = 75°, we get

=>  [tex]Sin(B) = \frac{AC}{BC} = > Sin(75) = \frac{AC}{12}[/tex]

=>  [tex]AC = 0.96 * 12 = > AC = 11.59[/tex]

Similarly, [tex]Tan(B) = \frac{AC}{BC} = > Tan(75) = \frac{11.59}{BC}[/tex]

=>  [tex]BC = \frac{11.59}{3.73} = > BC = 3.10[/tex]

Now, we have AC = 11.59cm and BC = 3.10cm putting these values in the Area of the Triangle we get :

Area = [tex]\frac{1}{2} *b*h[/tex]  => Area = [tex]\frac{1}{2}[/tex] * BC * AC

Area =  [tex]\frac{1}{2}[/tex] * 3.10 * 11.59  =>  Area = 18

Hence, we get the Area of Δ ABC = 18cm²

Step-by-step explanation:

Ethan makes in a week = $812.5

Given :

Total sales for the week = $1250

a guaranteed salary = $500

paid a commission on top of his base salary (Percentage commission) = 25%

Time and work problem:

Work Done = Time Taken × Rate of Work

Rate of Work = 1 / Time Taken

Time Taken = 1 / Rate of Work

If a piece of work is done in x number of days, then the work done in one day = 1/x

Total Wok Done = Number of Days × Efficiency

Efficiency and Time are inversely proportional to each other

X:y is the ratio of the number of men who are required to complete a piece of work, then the ratio of the time taken by them to complete the work will be y:x

Solution :

Amount of commission earned = 25% of $1250

= 25/100 × $1,250

= 0.25 × 1250

= $312.5

Total earnings = Base salary + Amount of commission earned

= $500 + $312.5

= $812.5

Ethan makes in a week = $812.5

In the real world, in artificial design, or in abstract concepts, a pattern is a regularity. As a result, a pattern's components repeat in a predictable way. Any of the senses can directly witness patterns, which are types of patterns made of geometric shapes and frequently repeated like wallpaper designs. On the other hand, abstract patterns in science, math, or language might only be visible through analysis. In actuality, direct observation entails recognizing visual patterns, which are common in both nature and art. Natural visual patterns are frequently chaotic, hardly ever precisely repeat, and frequently contain fractals. Spirals, meanders, waves, foams, tilings, fissures, and patterns produced by rotational and reflective symmetries are examples of natural patterns.

If there is an increase in the equilibrium quantity of hamburgers, the supply shift in the market must have been greater than the demand shift.

Assuming that all demand-shift factors remain constant, the hamburger demand curve illustrates the relationship between hamburger price and quantity required by consumers. The factors influencing how many hamburgers consumers desire to purchase at a particular price are known as demand determinants.

If the price of hamburgers increases, the demand curve will move from the previous price to the new price. However, if any of the demand-shift variables change, such as the cost of hot dogs, the cost of hamburger buns, or the income of hamburger consumers, the demand curve will alter.

Demand is where the demand curve is located. Demanded quantity is the volume that customers want to purchase.

The position of the supply curve is referred to as supply. The quantity of supplies you desire to sell is referred to as the quantity supply.

In this instance, an increase in supply will result in a fall in the equilibrium price and a movement all along the demand curve. The quantity demanded changes, while the demand curve does not.

Given function:

Let the inverse is y = f⁻¹(x).

Swap x and y in the given function and solve for y:

The inverse of the given function is:

Answer:

f-¹(x) = √(x)/3

Step-by-step explanation:

Now we have to,

→ find the inverse of f(x)=9x²

Then the inverse function will be,

→ f(x) = 9x²

→ y = 9x²

→ 9y² = x

→ y² = x/9

→ y = √(x/9)

→ [ y = √(x)/3 ]

Hence, the inverse is √(x)/3.

I assume you want the volume of the shape with the given cross sections. In the [tex]x,y[/tex]-plane, the base is set

[tex]\left\{(x,y) ~:~ 0\le x\le 2 \text{ and } 0 \le y \le 2-x\right\}[/tex]

Each cross section is a square plate with side length [tex]2-x[/tex] (the vertical distance between the [tex]x[/tex]-axis and the line [tex]y=2-x[/tex]) and thickness [tex]\Delta x[/tex], hence volume [tex](2-x)^2\,\Delta x[/tex].

As [tex]\Delta x\to0[/tex] and the number of cross sections grows to infinity, the total volume of the plates converges to volume of the solid [tex]S[/tex], given by the definite integral

[tex]\displaystyle \int_0^2 (2-x)^2 \, dx = \int_0^2 x^2 \, dx = \frac{2^3-0^3}3 = \boxed{\frac83}[/tex]

(where we make the substitution [tex]2-x\mapsto x[/tex])

The volume of the cone with radius 3 and height of the cone 6 is 56.52.

Any shape's volume in geometry is the area it takes up in a three-dimensional space. As a result, the space occupied by a cone in three dimensions is known as its volume.

The formula for the radius of a cone is given as:

r = √( 3 × V / π × h)

Where h is the height of the cone, V is the volume of the cone.

Now, squaring the above equation.

(r)² = [  √( 3 × V / π × h) ]²

r² = [ √ (3 × V) / √ ( π × h ) ]²

3V = π × r² × h

V = π × r² × h / 3

We have,

r = 3, h = 6, and π = 3.14

V = ( 3.14 × (3)² × 6 / 3 )

V = 3.14 × 3 × 6

V = 56.52

=======================================================

Explanation:

I'll use the substitution method.

Let's solve the second equation for x.

2y - x = -19

-x = -19-2y

x = 19+2y

Then plug that into the first equation

3x + 4y = -23

3( x ) + 4y = -23

3(19+2y)+4y = -23

3*19 + 3*2y + 4y = -23

57+6y+4y = -23

57+10y = -23

10y = -23-57

10y = -80

y = -80/10

y = -8

Use this y value to find x.

x = 19+2y

x = 19+2(-8)

x = 19-16

x = 3

---------------------------

Summary:

We found that x = 3 and y = -8

The ordered pair solution is therefore (x,y) = (3, -8)

Technically you could have stopped once reaching y = -8, since choice B is the only one that fits the description. But it helps to have practice.
