Step-by-step explanation:
If he started reading from where he left off, and it's 5:30 and he is at page 160, and then he got to page 280 by 8:00, that is 2 hours and 30 minutes. so bring the reading time down into easier numbers so that 5-> 30 minute terms, then find out how many pages he read in 30 minutes. The difference between 160 pages and 280 pages is 120 pages. 120 divided by 30 equals 4. the amount of time between 3:30 and 5:30 is 2 hours which is 4-> 30 minute terms. So if it takes 30 minutes to read 4 pages then multiply 4 with 4 which equals 16, and finally subtract 16 from 160 and that's going to equal 144 pages.
(Sorry about the paragraph but i figured ide give you my reasoning and work just in case if i was wrong, ide like to know what i did if i am wrong. And if I'm right then that's how you show your work!)
Answer:
108 m
Step-by-step explanation:
If the shadow is 0.8 m but actual parking meter is 1.2 m it means the shadow shrinks original by a factor of similarly, if the shadow for the building is 72 m it means it has already been shrunk by a factor of and to get the actual height of the building then we can say that the height be A
Therefore, the actual building is 108 m
Answer:
Therefore this triangle is not possible. This is the reason the architect was not hired.
Step-by-step explanation:
i) In a triangle we know that the sum of any two sides should be greater than or equal to the remaining side.
ii) The sides of the triangle are 21 feet, 37 feet, 15 feet.
iii) If we add the two smaller sides we get 21 feet + 15 feet = 36 feet which is less than the remaining side which is 37 feet.
Therefore this triangle is not possible. This is the reason the architect was not hired.
