A Fire Safety Officer examined 120 schools, looking for faults in fire exit signs, fire extinguishers and fire alarm systems. He found 18 schools without proper fire exit signs, 24 schools with insufficient fire extinguishers and 15 schools with faulty fire alarm systems. 5 schools had exactly two faults, 4 schools had all the three faults, only one school had faults in fire extinguishers and the fire alarm system, and 8 schools had faults in the fire alarm systems only. Draw a clearly labelled Venn diagram to illustrate the given information. Hence, find the number of schools (a) without any of the three faults; (b) who had only insufficient fire extinguishers; (c) without proper fire exit signs only.

106 emergencies

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
