The Russian ice breaker you mall can move forward through 2.3 m thick ice at a speed of 5.5 km/h. Right and solve a multiplicati

viktelen [127]

Answer:

The Multiplication equation to find the number of hours taken to travel the distance is $5.5\times x=82.5$ .

It will taken <u>15 hours</u> by Russian ice breaker to travel a distance of 82.5 km through the ice.

Step-by-step explanation:

Given:

Thickness of the ice = 2.3 m

Speed while moving forward = 5.5 km/h

Distance to travel through the ice = 82.5 km

We need to write and solve the multiplication equation to find the number of hours taken to travel the distance.

Solution:

Let the number of hours taken to travel the distance be 'x'.

Now We know that;

By Distance formula;

Distance traveled is equal to Speed while moving forward multiplied by the number of hours taken to travel the distance.

framing in equation form we get;

$5.5\times x=82.5$

Hence The Multiplication equation to find the number of hours taken to travel the distance is $5.5\times x=82.5$

On Solving above equation we get;

Dividing both side by 5.5 we get;

$\frac{5.5x}{5.5}=\frac{82.5}{5.5}\\\\x=15 \ hrs$

Hence It will taken <u>15 hours</u> by Russian ice breaker to travel a distance of 82.5 km through the ice.

Charlotte is running at a rate of 9\,\dfrac{\text{km}}{\text{h}}9

finlep [7]

<h3>Answer: Charlotte's speed in meter/second is 2.5m/s.</h3>

Step-by-step explanation:

Given speed of Charlotte in kilometer per hour = 9 km/h

We need to find the Charlotte's speed in meter per second.

We know 1 kilometer = 1000 meter

And 1 hour = 3600 seconds.

Plugging those values of km and hour in given speed in km/h, we get

$9\ \frac{km}{h} = 9\times \ \frac{1000m}{3600 seconds}$

$=\frac{10m}{4s}= 2.5\ m/s$ .

Therefore,

<h3>Charlotte's speed in meter/second is 2.5m/s.</h3>

Identify the domain of the function shown in the graph.

ivanzaharov [21]

For this case, we find the equation of the line, for this we look for points where the line passes:

$(x1, y1) = (- 2,0)\\(x2, y2) = (- 10, -4)$

We found the slope:

$m = \frac {y2-y1} {x2-x1} = \frac {-4-0} {- 10 - (- 2)} = \frac {-4} {- 10 + 2} = \frac {- 4} {- 8} = \frac {1} {2}$

Thus, the equation of the line is:

$y = \frac {1} {2} x + b$

We substitute a point to find "b":

$0 = \frac {1} {2} (- 2) + b\\0 = -1 + b\\b = 1$

Finally:

$y = \frac {1} {2} x + 1$

Now, the domain is given by all the values for which the function is defined.

It is observed that "x" can take any value, that is, it is defined for all real numbers.

Option A
