So basically, 9 cakes need 225 grams of flour
Therefore 1 cake needs:
= 25 grams of flour
Moreover, 20 cakes need: 20 × 25 = 500 grams of flour
500 g > 475 g
Marian does not have enough flour to make 20 cakes
Answer:
93 degrees
Step-by-step explanation:
First, you would need to observe the image and see where to start off. You can see that there is a triangle below the "?" and you would be able to get the answer if you can find the measures of the small triangle(because of vertical angles) So,
180-127= 53.
180-146=34.
Since the angles of a triangle adds up to 180 degrees, 53+34+x=180.
x=93
Now, just flip the angle around and "?" = 93 degrees.
You're thinking b=1 will always give an integer, certainly true.
Then you think b=-1 will also always give an integer, so
Answer: ±1
Then you remember that a/b may not be a reduced fraction, so other bs beside the unit make give integers. The condition for an integer is
b | a
read 'b divides a' meaning a is a multiple of b.
Then you realize that a and b might not even b integers themselves.
Let's say the above answer is correct with the additional criteria that a and b are integers with no common factors.
sinh(ln(4)) = (exp(ln(4)) - exp(-ln(4)))/2 = (4 - 1/4)/2 = 15/8 = 1.875
sinh(4) = (exp(4) - exp(-4))/2 ≈ 27.28992
