Answer:
6 cups to make 126 cookies
Step-by-step explanation:
dozen = 12 cookies
7 x 12= 84
126 - 84 = 42
so you will have to make 42 cookies more and that will be 2 more cups of flour
it total is 6 cups to make 126
Make an equation:
x= 16% x 50
x= 16 50
---- x ---- Cross Multiply
100 1
x= 16
------ = 8
Answer:
The ribbon is 28.4 meters
Step-by-step explanation:
Given the box is 5m high, 6m long, and 8m wide,
we have a right angled triangle with hypotenuse = unknown, x, say
Opposite = 5m and 8m
Then, by Pythagoras theorem
x² = 5² + 8²
x² = 25 + 64
x² = 89
x = √89 ≈ 9.4m
The ribbon is now (5 + 6 + 8 + 9.4)m = 28.4m
You have to isolate the variable just as if there was an equal sign
34280 + d + 1000 > 3680 (subtract 1000 from both sides)
34280 + d > 2680 (subtract 34280 from both sides)
d > -31600
-15 is already rational itself, but it as a fraction:
-15/1
