Answer:

Step-by-step explanation:
This triangle is a 30°-60°-90° triangle, so you should always remember the rule shown in the picture. Because y is across from the 60° angle, it will be
. 3 is x because it is across from the 30° angle, so y will be
.
Answer:
The Multiplication equation to find the number of hours taken to travel the distance is
.
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;

Hence The Multiplication equation to find the number of hours taken to travel the distance is 
On Solving above equation we get;
Dividing both side by 5.5 we get;

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

Step-by-step explanation:
Given lines,
y = 2x - 5,
y = -x + 1
Subtracting these two equations,
0 = 3x - 6


By first equation,

Thus, point of intersecting would be (2, -1).
Now, the equation of a line is y = mx + c,
Where,
m = slope of the line,
So, the slope of the line
is 1/2.
∵ two parallel lines have same slope.
Hence,
Equation of the parallel line passes through (2, -1),



Answer:
2.5 years
Step-by-step explanation:
Given data
P=9000
r= 1.25%
A= 9281.25
The simple interest expression is given as
A=P(1+rt)
substitute
9281.25= 9000(1+0.0125*t)
9281.25=9000+112.5t
collect like terms
9281.25-9000=112.5t
281.25= 112.5t
t= 281.25/112.5
t= 2.5
Hence the time is 2.5 years
