Answer:
72 in²
Step-by-step explanation:
We obtain the value of EC:
From Pythagoras :
EC = √CD² - DE²
EC = √10² - 6²
EC = √100 - 36
EC = √64
EC = 8
To obtain AE:
AE = √AB² - BE²
AE = √(√52)² - 6²
AE = √52 - 36
AE = √16
AE = 4
Hence, we can obtain the areas of each triangle :
△ABE = △ADE
△BCE = △CDE
AREA OF △ABE = 1/2 * base * height
= 1/2 * 4 * 6 = 12 in²
AREA OF △BCE = 1/2 * base * height
= 1/2 * 6 * 8 = 24 in²
HENCE, total area of fabric :
(2 * 12) + (2 * 24)
24 in² + 48 in²
= 72 in²
Ok so
250 left for student desks
250≥8n
n=number of desks
solve
divide both sides by 8
31.25≥n
round down since we cannot have a decimal desk
31 desks
but, the teacher has 1 desk also so add 1
31+1=32
Simplified ; log(6)
Decimal ; 0.77815125
Hope this was helpful !
Answer:
first you need to divide -1.8 from both sides so that would end up like this :
n=30
Step-by-step explanation:
Answer:
1) $0-22,500.
2) $500.
Step-by-step explanation:
1) A good scale to use for this question would be $0-22,500 at least. You would start with 0 because if you have $0 then you will get no car. And all the way to at least $22,500 because that is the average cost of an SUV at that dealership within 10 years and to go any lower than that would make it inaccurate.
2) 500 would be the best interval to use for this question because 22,500 ends in 500 which means when you count by 500 you will easily get to 22,500 without counting by 1's.
Hope This Helps!
