One batch of cookies makes 18. How many batches will you need to make to be sure you
have at least 100

6

Step-by-step explanation:

100/18=5 1/2

18*6=108

Answer : 18x5=90 18x6=108

Step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
