Answer:
Total number of eggs in basket = 56
Step-by-step explanation:
Let z be the total number of eggs
Green eggs = × z ........1
Blue eggs = × z .......2
Rest of eggs = 26 ........3
The addition of 1, 2 and 3 is equal to z
× z +
+ 26 = z
+ 26 = z ∵GCF for 4 and 7 is 28
+ 26 = z
15z + (26 × 28) = 28z ∵ multiply both sides by 28
15z + 728 = 28z
28z - 15z = 728 .......... rearranging above equation
13z = 728 ⇒ z = ⇒ z = 56
Total number of eggs = z = 56
Answer:
Building is 56.58 feet long.
Step-by-step explanation:
Consider the provided information.
An aerial photograph from a U-2 spy plane is taken of a building suspected of housing nuclear warheads.
When the photograph is taken, the angle of elevation of the sun is 30°.
By comparing the shadow cast by the building in question to the shadows of other objects of known size in the photograph, scientists determine that the shadow of the building in question is 98 feet long.
As we know:
The value of tan 30 degrees is
Hence, Building is 56.58 feet long.
