Step-by-step explanation:
as I can see this the answer is
x = 25/78
in decimal
x = 0.320
The problem involves joint variation with variables y, x, and z. After finding the constant of variation, we substitute the given values into the joint variation equation and determine that x = 16.67
First, we establish the equation of joint variation, which in this context is y = kxz, where 'k' is the constant of variation. When y=13, x=26, and z=6, we insert these values into the equation to solve for 'k'. This gives us k = y/(xz) = 13/(26*6) = 0.08333.
Now that we have the constant 'k', we can find the value of 'x' when y=25 and z=18. We rearrange our equation to solve for 'x', resulting in x = y/(kz). Substituting the known values, we get x = 25/(0.08333*18) = 25/1.5 = 16.67. Therefore, if y varies jointly with x and z, and y=25 when z=18, then x = 16.67.

Step-by-step explanation:
What was the difference between the high and low temperatures?
The solution is, The area is 280.8 inches² of one triangular section.
Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
here, we have,
given that,
If the base of the panel is 31.2 inches and the height is 18 inches,
we know that,
Area of triangle = base × height ÷ 2
here, we have,
b = 31.2
h= 18
so, we get,
A = 18 × 31.2 ÷ 2
we know,
18 × 31.2 ÷ 2 = 280.8
so, A = 280.8
The area is 280.8 inches².
Hence, The solution is, The area is 280.8 inches² of one triangular section.
