Answer:
50°
I hope it will be useful.
Step-by-step explanation:
Since the triangle is isosceles(see the sides),
opposite angles to the equal sides are equal.
(Property of isosceles triangles)
v.i.z., 2x=100°
The value of y when x = 5 is 45
<h3><u>Solution:</u></h3>
Given that y varies directly with x. This can be written mathematically as:
y ∝ x
---- eqn 1
Where "k" is the constant of propotionality
Given y = 27 when x = 3. Substitute these values in eqn 1
<h3>k = 9</h3>
Substitute k = 9 in eqn 1
y = 9x ----- eqn 2
<u><em>To find: y = ? and x = 5</em></u>
Substitute x = 5 in eqn 2
Thus the value of y when x = 5 is 45
Answer: 15
Step-by-step explanation:
Area of a triangle = base * height.
Since the inside figure is a square, the base of the triangle must be 5.
To find the height: The length of the entire figure is 17; subtract 5 to account for the square, and you know that the remaining 12 must be divided easily on the right and left side; this shows that the height of the triangle on the left must be 6.
Plug these numbers into the formula: 5 * 6 / 2 = 15 :)
The answer is 1/40. You find it by substituting the variables for their corresponding numbers then solve. ((-3) + 2(2))/10(4)
Time is the independent variable and cost is the dependent variable because cost of renting depends on the number of hours rented.
Step-by-step explanation:
The answer for the first box is independent variable because the independent variable is a constant value and is usually of x-coordinate.
The cost is the dependent variable because the y-value depends on the change in x-value. It is given that the cost varies as the time increases. Hence, cost is a dependent variable.
Also, the costing of renting depends on the number of hours rented, since cost is a dependent variable and the the cost raises if the time rented increases.
Thus, Time is the independent variable and cost is the dependent variable because cost of renting depends on the number of hours rented.
