So they give us this
V=IR
V= 1.8
I=0.4
R=?
So we insert the thing that we know.
1.8=0.4*R
We need to leave our unknown value alone. So if our value of 0.4 is multiplying the unknown value it passes to the other side dividing.
So we have this.
Lastly we solve.
R=4.5ohms
1. Radius is half of the diameter so d = 2r
2. Circumference = 2pir OR pid. But the perimeter of a polygon, you just add the sides
Answer:
Find the value of x in each of the given figures.
Step by step explanation :
a. .. Let the triangle be ABC
we have to find the value of A
so
ATTQ ( According to the question) we have ::
B = 25°
C = 105° + ___ = 180° ( adjacent angles)
C = 75 ° = 180° - 105° ( transfer 105° from LHS to RHS)
The sum of all interior angles of a triangle is 180° .
so, A+B+C = 180°
A+ 25° + 75° = 180°
A+ 100° = 180°
A= 180° - 100°
A = 80°
therefore answer is 80°
b. .. Let the triangle be ABC.
we have to find the value of x
ATTQ , we have
A= 3x+2°
B=2x°
C = 152° + ___ = 180°
C= 180°- 152° = 28°
The sum of all interior angles of triangle is 180°
so, A+B+C = 180°
3x+2° + 2x° + 28° = 180°
first add the variables then numbers
5x° + 30° = 180°
5x° = 180° - 30°
5x ° = 150°
x° = 150° / 5
x = 30°
therefore answer is 30°

thank you so much..
You flip 3 coins 20 times and record the number of heads. The results are listed below. 2, 1, 0, 2, 2, 0, 2, 2, 3, 2, 1, 2, 1, 2

Assuming a is 0, b is 1, c is 2, d is 3
a= 2, b= 7, c= 9, d= 2
We simply substitute the values of x and check if the values of y match.
y(1) = 19,000
y(2) = 18,050
y(3) = 17,148
y(4) = 16,290
As is visible from the table, the first value quoted is incorrect.
