Answer:

[tex] 6.4 * 10^{3} km[/tex]

Step-by-step explanation:

Scientific notation can be defined as a way of expressing and writing a very small or large real number in decimal form. Generally, to use the scientific notation, we will multiply the real number by a power of 10.

Given that the length of Amazon River is 6,400 kilometers.

[tex] \frac{6400}{1000} = 6.4[/tex]

[tex] 1000 = 10^{3}[/tex]

Therefore,

6, 400 kilometers = 6.4 × 10³ kilometers.

Answer:

6 yards

Step-by-step explanation:

The pylon is 6 yards tall.

There are mainly two types of fractions proper fraction and improper fraction.In proper fraction numerator is smaller than the denominator and in improper fraction denominator is smaller than the numerator.

According to the given question

A pylon has some part of it below the ground and some part is above the ground and we have to find the total length of it.

Given [tex]\whole{3}\frac{1}{2}[/tex] yards is below the ground and [tex]\whole2\frac{1}{2}[/tex] yards above the ground.

∴Total length of the pylon is (7/2 + 5/2) yards.

= 12/2 yards.

= 6 yards.

The answer is £775 for hiring a car

The required answer would be the cost of hiring the car in euros is €775.

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

In August 2008, Eddie hired a car in Italy. The cost of hiring the car was £620

The exchange rate was £1 = €1.25

We have to determine the cost of hiring the car in euros (€).

According to the given question,

For the required solution, we have to multiply the exchange rate by the cost of hiring the car

The cost of hiring the car in euros (€) = 620 × exchange rate

The cost of hiring the car in euros (€) = 620 ×  €1.25

Apply the multiplication operation to get

The cost of hiring the car in euros (€) = €775

Therefore, the required answer would be the cost of hiring the car in euros is €775.

The equation in the standard from is 2x + 3y = -18.

The linear equation is the algebraic form of equation whose variable has the exponent of one. It is the combination of two variables and a constant value present in them.

For the given situation,

The equation is y = -2/3 x - 6

The standard form of linear equation is Ax +By = C,

where A,B,C are numbers and x,y are intercepts.

⇒ [tex]y=\frac{-2}{3}x -6[/tex]

Taking LCM on RHS,

⇒ [tex]y=\frac{-2x-18}{3}[/tex]

⇒ [tex]3y=-2x-18[/tex]

Rearrange the equation in the standard from,

⇒ [tex]2x+3y=-18[/tex]

Hence we can conclude that the equation in the standard from is           2x + 3y = -18.

Answer: 20

Step-by-step explaination: -4 minus 5x=20 because 4x5=20+-x=20

Answer:

x = 2

Step-by-step explanation:

To start, you want to isolate x.

To do so, get all the x terms to one side.

2x + 1 = 4x - 3

Subtract -4x on both sides.

-2x + 1 = -3

Then, subtract 1 on both sides.

-2x = -4

Finally, divide -2 on both sides.

x = 2

Step-by-step explanation:

The graph is a straight line graph. A straight line graph is used to represent a linear equation. A linear equation is represented by the equation: y = mx + c, where y is the dependent variable, x is the independent variable, m is the slope (rate of change) and c is the intercept.

A line passing through the point [tex](x_1,y_1)\ and\ (x_2,y_2)\[/tex] can be represented by the equation:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]

Let y represent the distance in miles and x represent the time in hours. From the graph, the line pass through (0.5, 100) and (3.5, 700). Hence using:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-100=\frac{700-100}{3.5-0.5} (x-0.5)\\\\y-100=200(x-0.5)\\\\y-100=200x-100\\\\y=200x-100+100\\\\y=200x\\\\To\ travel\ 480 \ miles,we\ substitute\ y=480\ and\ find\ x\\\\480=200x\\\\x=480/200\\\\x=2.4\ hours[/tex]
