The number of pounds required for the counter top is


The required expression is
.
Answer:
x = - 0.89
Step-by-step explanation:
x - 8.2 = - 9.09
x = - 9.09 + 8.2
x = - 0.89
Answer:
B) 4 3/4
Step-by-step explanation:
We are looking for the total weight of the fish that weight more than 1 1/4 lbs
There are 2 fish that weight 1 1/2 and 1 that weights 1 3/4
2 ( 1 1/2 ) + ( 1 3/4)
Change the 1st mixed number to improper fractions
2 ( 2*1+1)/2 + (1 3/4)
2 * (3/2) + 1 3/4
3 + 1 3/4
4 3/4
Answer:
4 or FISH
Step-by-step explanation:
The surface charge density:
S(igma) = Q / A
A = 1.6 * 10^(-2) * 1.6 * 10^(-2) = 2.56 * 10^(-4) m²
The electric field: E = S / E(psilon) o
E = 0.711 * 10^^(-9) / ( 2.56 * 10 ^(-4) * 8.85 * 10 ^(-12) ) =
= 0.3138 * 10 ^6 = 3.138 * 10^5 V/m
a ) Δ V = E d
Δ V = 3.138 * 10^5 V/m* 1.2 * 10^(-3) m = 376.56 V
b ) When d = 2.40 mm:
Δ V = 3.138 * 10^5 V/m * 2.40 *10^(-3) m = 753.12 V
