Answer:
The value of Z = 0.3066... Or 0.31.
Step-by-step explanation:
The formula of direct proportional is a=kb (where k is constant). Given that a=z=0.2 and b=x=15, equation is 0.2=15k,
k=0.2/15
k=0.0133333333333
If x is 23 then what is z?
z=0.0133333333333(23)
z=0.3066666 or 0.31
Answer:
A :)
Step-by-step explanation:
I believe the answer is A because on a line it equals 180 and because the angle of 8 is equal to 171, you still need to find 9 more degrees. You set 2x-33 equal to 9 and solve as a two step equation, and get the answer 21. Hope this helps :)
Answer:
The value of y is -2
Therefore the given point (8,y) becomes (8,-2)
Step-by-step explanation:
Step-by-step explanation:
Given that the line through the points (8, y) and (9, 1) and slope m is 3
To find y to the line through the points (8, y) and (9, 1) :
The formula for slope is
Let , be the given points (8, y) and (9, 1) respectively
Now substitute the values of the points and m=3 in the formula
( adding the like terms )
Therefore y=-2
Therefore the value of y is -2
Therefore the given point (8,y) becomes (8,-2)
Part (a)
<h3>Answer: 12.1</h3>
-----------------------
Work Shown:
We'll apply the sine rule since we have a known opposite side of AB = 10 and an unknown hypotenuse we want to find BD.
Focus on triangle ABD
sin(angle) = opposite/hypotenuse
sin(D) = AB/BD
sin(56) = 10/x
x*sin(56) = 10
x = 10/sin(56)
x = 12.062179
x = 12.1
Make sure your calculator is in degree mode.

Part (b)
<h3>
Answer: 15.1</h3>
-----------------------
Work Shown:
Draw an xy coordinate grid.
Place point A at the origin (0,0).
Point B is 10 units above this, so B is at (0,10).
Point C is at (18,10) since we move 18 units to the right of B.
Point D is at approximately (6.745085, 0). The 6.745085 is from solving tan(56) = 10/x for x.
Refer to the diagram below.
Apply the distance formula for the points C and D.
Segment CD is roughly 15.1 cm long.
