The equation variation for the electric circuit is  V = 25R.

How to find the equation variation of an electric circuit?

In each electric circuit, the voltage in a battery is measured in volt and the resistance in the circuit is measured in ohms.

The voltage, V is directly proportional to the resistance, R. In a given circuit the voltage is 200 volts, when the resistance is 8 ohms.

The equation variation for the circuit can be represented as follows:

V α R

V = kR

where

k = constant of proportionality

Therefore,

voltage = 200 volts

resistance = 8 ohms

200 = 8k

k = 200 / 8

k = 25

Therefore, the equation is V = 25R

What is the answer for x+6x

The answer is 7x

Step-by-step explanation:

The x is the coefficent and every x has a coefficent  even if it doesn't have  number because the coefficent   represent how many x's there are so it is one x plus 6 x and that equal seven x. The x can be anything but one of something plus 6 equals 7.

the answer would be 13.89

Answer:

Step-by-step explanation:

well just go throught the factors as far as you can ik from my personal mindset that 14*14= 196 so if i go bk and  calculate 13*13=169 which means its gonna be in between 13 and 14. so to figure this out we have to write it out. so we can try 13.5*13.5=182.25 so we have to go higher  13.89*13.89=192.9321 which means it has to be 13.89 rounded to the nearest hundreth.

Answers

Answer:

Step-by-step explanation:

In other to meet up with her target, Abigail would have to cover 4 miles every day.

Target = 37 miles

Covered miles = 17 miles

Number of miles left to cover :

Target - miles covered

Number of miles left = (37 - 17) miles = 20 miles

Number of miles to cover per day :

20 miles ÷ 5 = 4 miles

Hence, Abigail would have to cover 4 miles every day.

Answer:

π(6 cm) (10 cm)

Step-by-step explanation:

As we know that

The formula to calculate the lateral surface area of the cone is πrl

where

r denotes the radius i.e. 6 cm

l denotes the length i.e. 10 cm

So based on the above information

The expression that shows the lateral surface area of the cone is

π(6 cm) (10 cm)

Therefore the third option is correct

If p varies jointly as q and r, and p = 150 when q = 18 and r = 5, find q when p = 345 and r = 9.​

Answers

Answer:

Step-by-step explanation:

P varies jointly as q and r

 

p=k* q r

 

150 =k *(18)(5)

 

150 = k*(90)

 

150/90 = k

 

5/3 = k

 

find q when p=345 and r =9

 

p=k* q r

 

345 = (5/3) * q *9

 

345 = 45 q / 3

 

1035 = 45 q

 

q=23

The required value of the q in the proportionality relationship is given as q = 23.

Given that,

p varies jointly as q and r, and p = 150 when q = 18 and r = 5, find q when p = 345 and r = 9.​

What is proportionality?

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

P varies jointly as q and r

p =k × q r  - - - - - (1)

150 =k × 18× 5

k = 5 / 3

Put k = 5/3, p = 345 and r = 9 in equation 1

345 = (5/3) × q ×9

q = 23

The required value of the q in the proportionality relationship is given as q = 23.
