Answer:

Step-by-step explanation:

Given

Call out fee =  £35

Per hour =  £30

Time = 2 hours

Per light switch = 12 minutes

Required

Cost of wiring a house with 10 light switches

First, the minutes on the 10 light switches should be calculated'

If time per light switch is 12 minutes;

then

Time for 10 = 12 minutes * 10

Time for 10 = 120 minutes

[Convert to hours]

Time for 10 = 2 hours

Next is to calculate the total time spent altogether

Time = 2 hours + Time spent on 10 light switches

Time = 2 hours + Additional 2 hours

Time = 4 hours

Total Charges = Call out fee + Charges per hour * Time

Total Charges = £35 +  £30 * 4

Total Charges = £35 +  £120

Total Charges = £155

Margarita [4]

The investment will be worth $4686.62 after 5 years.

<u>Step-by-step explanation</u>:

Principal, P = 3700

Rate, r = 4.75% = 0.0475

Number of years, t = 5 years

Number of times compounded, n = 5 times

Amount = P(1 + r/n)^nt

⇒ 3700 (1 + 0.0475/5)^25

⇒ 3700 (5.0475/5)^25

⇒ 3700 (1.0095)^25

⇒ 4686.62

∴ Amount = $4686.62

Vesnalui [34]

Answer:

The correct option is;

26.8

Step-by-step explanation:

The given parameters are;

The perpendicular bisectors of the sides of ΔMNP = Segments OQ, OR, and OS

Therefore;

in Segment MN, segment QM = segment QN, by definition of bisected line

Segment OQ = Segment OQ by reflexive property

∠OQM = ∠OQN = 90° by definition of perpendicular bisector

∴ ΔOQN ≅ ΔOQM, by SAS rule of congruency

Segment MO ≅ Segment ON by Congruent Parts of Congruent Triangle are Congruent, CPCTC

Segment MO = Segment ON = 26.8, by definition of congruency

Segment MO = 26.8
