Answer:
Step-by-step explanation:
The water district has been charging its customers a flat rate of $3.25 per HCF. If a family uses an average of 56 HCF per month, the total charge would be
3.25 × 56 = $182
Because of a drought emergency, it is instituting a block rate of $3.60 for the first 20 HCF and $4.85 for the next 40 HCF. If a family uses an average of 56 HCF per month, the total charge would be
(3.6 × 20) + 4.85(56 - 20)
= 72 + 174.6
= $246.6
The increase in the charge is
246.6 - 182 = $64.6
The percent by which their average bill increased under the block system is
64.6/182 × 100 = 35.5%
Answer:
One possible solution is 5 + i√3.
(there are 2 solutions 5 + i√3 and 5 - i√3).
Step-by-step explanation:
(x - 5)^2 + 5 = 2
(x - 5)^2 = -3
Take square roots of both sides:
x - 5 = √-3
x - 5 = i√3
x = 5 ± i√3.
The solutions are both complex numbers.
Answer:
X = 67°
Step-by-step explanation:
The sum of every triangle’s interior angles is 180°. First subtract the given angle, 23°, from 180°. This equals 157°. Next you can see that one of the triangle’s angles has a right angle mark. This mark means it’s a right angle and all right angles are 90°. Take 157° and subtract 90°. This equals 67°. This means the remaining angle equals 67°.
