Sara was making a cookies and she needs ½ cup of Chocolate chips and 2/3 cup of sugar. She accidently put in 1 cup of sugar. How many cups chocolate chips does she need now?

3/4 cups of Chocolate chips is needed

Step-by-step explanation:

Sara was making a cookies and she needs ½ cup of Chocolate chips and 2/3 cup of sugar. She accidently put in 1 cup of sugar. How many cups chocolate chips does she need now?

From the above question:

2/3 cup of sugar = ½ cup of Chocolate chips

1 cup of sugar = x

Cross Multiply

2/3 cup of sugar × x = ½ cup of Chocolate chips × 1 cup of sugar

x = ½ cup of Chocolate chips × 1 cup of sugar/ 2/3 cup of sugar

x = 1/2 ÷ 2/3

x = 1/2 × 3/2

x = 3/4 cups of Chocolate chips

Therefore, for 1 cup of sugar , 3/4 cups of Chocolate chips is needed

(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
