The electrical resistance of aire is directly proportional to its length. If a 45-foot long wire has a resistance of 9 ohm(s), f

wolverine [178]

The resistance is proportional to the length.
You know that 45/9=5
So the ratio (proportionality) is 5.
So, for a 75 ft wire, the resistance is 75/5 = 15 ohms

HELP PLEASE NEED ANSWERS

r-ruslan [8.4K]

Answer:

Answer: -30

Step-by-step explanation:

${(8 - 10)}^{2} - 30 \div 5 \times 6 + 2$

BODMAS

let's first solve the bracket:

$= {( - 2)}^{2} - 30 \div 5 \times 6 + 2 \\ = 4 - 30 \div 5 \times 6 + 2$

then let's divide:

$= 4 - (30 \div 5) \times 6 + 2 \\ = 4 - 6 \times 6 + 2$

then let's multiply:

$= 4 - (6 \times 6) + 2 \\ = 4 - 36 + 2$

simplify:

$= - 30$

The reflexive property makes triangle XYW congruent or equal to ZWY by

Marta_Voda [28]

Answer: D: SSS Congruency

Step-by-step explanation:

- SSS congruency stands for side-side-side congruency

- if the 3 side lengths are equal for both triangles they are equivalent

- the reflexive property states that an angle, line segment, or shape is always congruent to itself

- so the reflexive property is just saying that WY = YW, therefore creating 3 equal sides for both triangles

- so the triangles are congruent by SSS

hope this helps :)
