Answer:
h = 2
b = 3
Step-by-step explanation:
to find 'h' we can use the ratio of sides in a 30-60-90° triangle which, respectively, is 1 : : 2
so we can set up this proportion:
h/2 = 1/
cross-multiply:
h = 2
to find 'b' we can use the ratio of sides in a 45-45-90° triangle which, respectively, is 1 : 1 :
we can set up this proportion:
3/b = 1/
cross-multiply:
b = 3
Answer: 14%
Step-by-step explanation:
The probability of a chocolate cupcake being sold would be equal to the amount of chocolate cupcakes divided by the total number of cupcakes.
= 2/(2+1+5+6)
= 2/14
= 1/7.
We convert 1/7 to a percent.
When rounded to the nearest whole percent, we get the probability as 14%.
