It’s 4

The area of a rhombus is diagonal 1 x diagonal 2 / 2. Since we know the area is 120 and the diagonal 1 is 15 we would divide them and get 8. But then you would do divide 8 by 2 because of the last part of the formula for a rhombus and get 4.

Hope that helps!

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

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 15 hours 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 15 hours by Russian ice breaker to travel a distance of 82.5 km through the ice.
