Answer:
The value of y given the values of x and z in the question is -734.85
Step-by-step explanation:
This is a joint variation question.
First, we are made to know that y varies jointly as x and z.
The equation for this can be written as;
y = k * x * z
Where k is the constant of proportionality.
Let’s calculate k first.
117 = k * (-3) * (-11)
33k = 117
K = 117/33 = 3.55
Now, we proceed to get what y is when x = -9 and z = 23
Let’s plug these values into the initial equation written.
y = k * x * z
We use the value of k calculated above;
y = 3.55 * (-9) * (23) = -734.85
To reduce a fraction divide the numerator and the denominator by their greatest common factor, GCF. ... The numerator and the denominator of the fraction are coprime numbers (no common prime factors, GCF = 1), the fraction cannot be reduced (simplified): irreducible fraction.
Answer:
Rhombus
Step-by-step explanation:
Shape of a playground is a quadrilateral
It is given that all sides of a quadrilateral are= 27 feet
Since all the sides of a quadrilateral are equal that it can be either a rhombus or it can be a square
Two angle are 65° each
And other two angers are 115° each
65°+ 115°= 180°
It forms a co-interior angle
Hence the quadrilateral is a parallelogram
Since all the four sides of parallelogram are equal, than the given figure must be rhombus
Hence, geomatric shape best describes the shape of the playground is Rhombus.
It is 180 because it rotates
When you are checking your answers, your formula should read out as 9(2.222) - 8 = 12, which is simply filing in the x value that you calculated (it comes out to 11.998 which is correct). You wrote it out as 9(2.22) - 8 = -6, which is why your checking process was incorrect
