Answer:
Step-by-step explanation:
we have that
The scale drawing is

we know that
Using proportion find out the actual dimensions of the volleyball court
Let
x -----> drawing court lengths in cm
y ----> court lengths in cm
For x=40 cm

For x=80 cm

Find the equation for the proportional relation ship between drawing court lengths x in centimeters and court lengths in y centimeters
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
For x=40 cm, y=900
substitute
----->
The equation is
Answer:
Around 24 degrees
Step-by-step explanation:
*Make sure calculator is on degree mode*
Try to draw out triangle--it helps
Need to use law of sines... this is where an angle and the side that opposes it are equal to each other. For example, Angle U is equal to 9.7

Multiply 4 and sin90 and then divide the product by 9.7
Use
on calculator to convert the answer into degrees
Answer:
a) F
b) B, E, D
Step-by-step explanation:
a) The segment with the greatest gradient has the largest change in y-values per unit change in x-values
From the given option, the rate of change of the <em>y </em>to the<em> </em>x-values of B = the gradient = (4 units)/(2 units) = 2
The gradient of F = (-3units)/(1 unit) = -3
The gradient of A = 4/4 = 1
The gradient of C = -2/5
The gradient of D = 2/6 = 1/3
The gradient of E = 3/4
The segment with the greatest gradient is F
b) The steepest segment has the higher gradient
From their calculated we have;
The gradient of segment B = 2 therefore, B is steeper than E that has a gradient of 3/4, and E is steeper than D, as the gradient of D = 1/3
Therefore, we have;
B, E, D.
8/1 x 2/3 = 16/3. 16/3 = 5 1/3
And integer is a whole number, negative or positive, with no decimals or fractions.
A is true.
B is true.
A rational number is a number that doesn't have an infinite number of decimal.
C is true.
D is false.
<u>The answer is D</u>
