Let the number be x.
Half of that number = x / 2
One third of the number = x / 3
= x / 2 + x / 3 = 22. LCM = 6.
= (3x + 2 x) / 6 = 22.
5x / 6 = 22. Cross multiply
5x = 6 * 22.
5x = 132 Divide both sides by 5.
x = 132 / 5
x = 26.4
The number is 26.4. Cheers.
So we can write
12% of x = 36
12/100 x = 36
x = 36 x 100/ 12
x= 300
So, 300 cookies were ordered in total.

Answer:
21.8 + (3/2)(7.1)(13)
Step-by-step explanation:
The surface area (SA) is the sum of the base area (B) and lateral area (LA). The lateral area is the sum of the areas of the three face triangles.
SA = B + LA
LA = 3((1/2)bh)) . . . . b is the base length of the triangle, and h is its height
Using appropriate substitutions, we have ...
SA = 21.8 + (3/2)(7.1)(13)
Total jellybeans pulled out: 15 + 20 + 12 + 8 = 55
Proportion of yellow jellybeans: 20 / 55 = 4/11
