Answer:
<h2>One</h2>
Step-by-step explanation:
Given the value 78247 a s a stable number because at least one of its digits has the same value as its position in the number. The 4th number in the value is 4, this makes the number a stable number.
The following are the 3-digits stable numbers that appears in 78247
The first number is 824. This digits are stable numbers because 2 as a number is situated in the same place as the number (2nd position).
Hence, there are only 1 stable 3-digit numbers in the value 78247 since only a value exists as 2 in the value and there is no 1 and 3 in the value.
Answer:
Given:
length of the wire = 0.20 meters
magnetic field strength = 0.45 newtons/amperes meter
speed = 10.0 meters per second
emf = B * l * v
B = flux density ; l = length of the wire ; v = velocity of the conductor
emf = 0.45 newtons / ampere meter * 0.20 meters * 10.0 meters/seconds
emf = 0.90 volts
The emf produced is 0.90 volts.

Answer:
(A)
Step-by-step explanation:
Given the equations:

Substitution simply means replacing the variable y in the second equation with its equivalent x+3 from the first equation.
Substitution of y into
gives us:

The correct option is A.
Answer:
The answer is D
Step-by-step explanation:
∠C + ∠E = 180°(consecutive angles)
7x +11° + 7x + 1° = 180°
14x + 12° = 180°
14x = 168°
x = 12°
∠E = 7x + 1°
= 7(12°) + 1
= 85°
the whole statement is true, make sure you read all of your choices next time and list them below.
