Step-by-step explanation:

Please forgive me if I am wrong :)

Answer:

there was a 56% decrease change

There is a [tex]\boldsymbol{52\%}[/tex] percentage change as a number changes from [tex]50[/tex] to [tex]76[/tex].

Type is increase in percentage.

A percentage is a figure or ratio that is stated as a percentage of one hundred. The percent sign, " [tex]\%[/tex] ", is frequently used to represent it.

Difference between new and old number [tex]=76-50[/tex]

                                                                      [tex]=\boldsymbol{26}[/tex]

Percentage change [tex]=\frac{76-50}{50}\times 100[/tex]

                                  [tex]=\boldsymbol{52\%}[/tex]

So, there is a [tex]\boldsymbol{52\%}[/tex] increase.

Answer:

2267 km

Step-by-step explanation:

1890 km/3.5 hours = 2267 km/4.2 hours

2268 km far will the plane fly in 4.2 hours if it maintains the same air speed.

How far will the plane fly in 4.2 hours if it maintains the same air speed?

The formula speed = distance ÷ time can be rearranged like any other equation. The formula can be rearranged in three ways: speed = distance ÷ time. distance = speed × time.

Given,a plane flies 1890 km in 3.5 hours.

So, distance = 1890 km and time = 3.5 hours.

We know,

Distance = Speed × Time

For example, If speed of a car is 20 m/s and the car travel 60 s then the car cover total distance

[tex]= 20 \times 60 = 1200 \: m[/tex]

Again

[tex]speed = \frac{distance}{time}[/tex]

According to question,

Speed

[tex] = \frac{distance}{time} \\ = \frac{1890}{3.5} \\ = 540 [/tex]

So, speed of the plane is 540 km/hour.

Again given time is 4.2 hours

So, Distance = Speed × Time

[tex] = 540 \times 4.2 \\ = 2268 \: km[/tex]

Answer:

x = 2  ⇒  point (2, 0)

Step-by-step explanation:

The x-intercept is the place where the line crosses the x-axis. This is also when y = 0.

So, set y equal to 0 and solve for x:

6x - 5y = 12

6x - 5 * 0 = 12

6x = 12

x = 12/6 = 2

The x-intercept, thus, is at x = 2.

Answer:

Step-by-step explanation:

Company A = 18 eagles for $49.32

Price per eagle = $49.32 / 18

= $2.74

Company B = 16 eagles for $43.36

Price per eagle = $43.36 / 16 eagles

= $2.71

Company C = $41.55 for 15 eagles

Price per eagle = $41.55 / 15 eagles

= $2.77

The company which has the best buy is company C, they sell 1 eagle for $2.77 (highest selling price among the three companies)

Step-by-step explanation:

Answer:

Width of the rectangular prism

It is given to us that the volume of the rectangular prism is calculated by the given formula :-

v = lwh

Where,

v = volume

l = length

w = width

h = height

Now,

In the question we are given :-

v = 138.24 cubic inches

h =  9.6 inches

l = 3.2 inches

w = ?

Substitute these values in the volume formula given :-

138.24 = 3.2 * w * 9.6

138.24 = 30.72 * w

w = 138.24/30.72

w = 4.5

⇒ The width of the rectangular prism is 4.5 inches.

The required width of the rectangular prism is 4.5 inches.

Given information:

The volume of the rectangular prism is defined as,

[tex]V=lwh[/tex]

where l is the length, w is the width, and h is the height of the prism.

The volume of the prism is 138.24 cubic inches.

The height of the prism is 9.6 inches, and the length of the prism is 3.2 inches.

So, the width of the prism can be calculated as,

[tex]V=lwh\\138.24 =3.2\times w\times 9.6\\138.24 =30.72\times w\\w=\dfrac{138.24}{30.72}\\w=4.5\rm \; inch[/tex]

Therefore, the required width of the rectangular prism is 4.5 inches.
