Answer:
yes
Step-by-step explanation:
6:3 and 8:4
6:3
Divide by 3
6/3: 3/3
2:1
8:4
Divide by 4
8/4: 4/4
2:1
They are the same so they form a proportion
Answer:
WX = 7.9
Step-by-step explanation:
By applying tangent rule (law of tan) in the given right triangle WXY.
tan(W) =
tan(27)° =
0.509525 =
WX =
WX = 7.85
WX ≈ 7.9
Therefore, length of side WX is 7.9 units.
Answer:
Relationship is linear as r is closest to 1.
Step-by-step explanation:
From statistics we know that,
Putting all the values from the table,
we get corelation factor as 0.9995
Therefore, the relationship is linear as r is closest to 1.
Answer:
x=11
BC=19
Step-by-step explanation:
AB+AC=AC this is because B is in between A and C. So now we can substitute all of the line segments, so we have
x+2x-3=30 Now you add 2x and x
3x-3=30 Now you add 3 to both sides so you can get 3x alone on one side
3x=33 Now you divide both sides by 3 so you get the x alone on one side
x=11
The next step is to substitute x to find BC.
BC=2x-3 Substitute the x with 11
BC=2(11)-3 Then multiply 2 and 11 because that is the rule with parenthesis
BC=22-3 then subrtact the 3 from 22
BC=19
You can check your work by doing AB+BC=AC
11+19=30 substitute your answers and then add them together
30=30
