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 proportionalityTherefore,
voltage = 200 volts
resistance = 8 ohms
200 = 8k
k = 200 / 8
k = 25
Therefore, the equation is V = 25R

Find the surface area of the
rectangular prism.
4 ft.
12 ft.
9 ft.
[? ] sq ft.
Answers
Answer:
384Step-by-step explanation:
Given,
Dimensions of the rectangular prism = 9ft, 12ft and 4ft
Therefore,
Surface area of the rectangular prism
= 2( lb + bh + lh)
[tex] = 2(12 \times 9 + 9 \times 4 + 12 \times 4) {ft}^{2} [/tex]
[tex] = 2(108 + 36 + 48) {ft}^{2} [/tex]
[tex] = 2 \times 192 {ft}^{2} [/tex]
[tex] = 384 {ft}^{2} [/tex]
Hence,
Surface area of rectangular prism is 384 sq. ft (Ans)
Which expression represents the lateral surface area of the cone?
8 cm
6 cm
10 cm
LA-xi
0 (x)(3 cm)(10 cm)
O (*)(6 cm)(8 cm)
O (*)(6 cm)(10 cm)
N
Answers
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
Hence, the same would be relevant

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.
