Answer:

$9.65$

Step-by-step explanation:

We are given with a mixed fraction $9\frac{13}{20}$

In order to solve a mixed fraction, we split the terms and perform addition.

which means $9\frac{13}{20}$ can be written as-

$9\frac{13}{20} = 9 + \frac{13}{20}$

⇒ $9\frac{13}{20} = 9 + 0.65$

⇒ $9\frac{13}{20} = 9.65$

∴ $9\frac{13}{20}$ can be written as $9.65$ in decimal

$9\dfrac{13}{20}=9+\dfrac{13}{20}=9+\dfrac{13\cdot5}{20\cdot5}=9+\dfrac{65}{100}=\boxed{9.65}$

Answer:

O 81 km per hour

Explanation

Given parameters:

Number of days traveled = 3 days

Distance covered on the first day = 1080km

Time of travel = 10hrs

Rate of travel = 108km/hr

Time of travel on second day = 12hrs

Rate of travel = 90km/hr

Time of travel on third day = 18hrs

Rate of travel = 60km/hr

Unknown

Average speed = ?

To find the average speed, we sum the distances and divide by the sum of the time.

Average speed = $\frac{Total distance}{total time}$

we do not know the second and third distances;

Distance = speed x time

D2 = 90 x 12 = 1080km

D3 = 60 x 18 = 1080km

Now;

Average speed = $\frac{1080 + 1080 + 1080 }{10 + 12 + 18 }$

Average speed = $\frac{3240}{40}$ = 81km/hr

The average speed is 81km/hr

Using coal, steam, and _____, the fischer-tropsch procedure converts coal into a liquid fuel.

ANTONII [103]

Answer:

Using coal, steam, and OXYGEN, the fischer-tropsch procedure converts coal into a liquid fuel.

Step-by-step explanation:

A series of chemical reactions in which hydrogen and carbon monoxide converges into liquid hydrocarbons by using a metal catalyst. This process is called The Fischer-Tropsch process.

Converting Coal into Liquid Fuel is know as Coal liquification.

IN Liquification process Oxygen, heat is used.

Therefore steam is for heat and oxygen to covert coal into liquid fuel.

if the following line segment is reflected across the x-axis what are the coordinates new endpoints A.) (-1,-6) and (-3,-2) B.)

Tasya [4]

Answer:

A.) (-1,-6) and (-3,-2)

Step-by-step explanation:

The given line segment has coordinates

(-1,6) and (-3,2)

The mapping for a reflection in the x-axis is

$(x,y)\to (x,-y)$

This implies that;

$(-1,6)\to (-1,-6)$

and

$(-3,2)\to (-3,-2)$

The correct choice is A.

Find the value of X. Write your answer in simplest form. What does X equal?

drek231 [11]

Given:

Given that the figure of similar triangles.

The altitude of the triangle is x.

The length of the left part is 30.

The length of the right part is 15.

We need to determine the value of x.

Value of x:

The value of x can be determined using the geometric mean theorem.

Thus, we have;

$\frac{\text { left }}{\text { altitude }}=\frac{\text { altitude }}{\text { right }}$

Substituting the values, we have;

$\frac{30}{x}=\frac{x}{15}$

Cross multiplying, we get;

$30 \times 15= x^2$

$450=x^2$

Taking square root on both sides, we have;

$15 \sqrt{2}=x$

Thus, the value of x is 15√2
