Answer:
80 km/ h
Step-by-step explanation:
1 mile = 1.6 kilometers
50 miles x 1.6 = 80 kilometers
Answer:
1 4/17
Step-by-step explanation:
3 1/2 ÷ 2 5/6
= 7/2 ÷ 17/6
= 7/2 * 6/17
= 21/17
= 1 4/17
Answer:
x=25 degrees
Step-by-step explanation:
x= 90 degrees - given(65 degrees)
x=90-65
x=25 degrees.
The angles add up to 90 degrees.
Answer:
Greatest possible number of solutions of these set of equations are 2
Step-by-step explanation:
We have been given two functions in the question.
x² + y² = 9
9x + 2y = 16
We know that the equation of circle is given by:
(x - h)² + (y - k)² = r²
However, if (h, k) is equals to (0, 0), the equation of circle becomes:
x² + y² = r²
Which is similar to the fist equation
x² + y² = 3²
Hence first equation is a circle.
As the second equation is a linear equation, it is simply a line.
We know that a line passing through the circle can intersect it at only 2 points.
Where points of intersection between both circle and line shows the solution.
So.
There are 2 possible solution to this set of equations
5(3n-2) is for sure the expression
