Answer:

<h2>19.596 feet</h2>

Step-by-step explanation:

Use the pythagorean theorem.

a^2 + b^2 = c^2

a = 20ft

c = 28ft

400 + b^2 = 784

b^2 = 384

b = 19.596

A mother shares a box of 20 chocolates in the same ratio as her children's ages . Calculate how many chocolates each child gets
Anni [7]
So a box of 20 chocolates is divided between a group of people based on age So the ratio for Sibusiso, Dorris, and Freddy is 2:3:5 Add these together, and you get 10 So to find how much each person gets, divide total amount of chocolates by total age So (20÷10) = 2 So multiply each age term by 2 and you have your answer (4:6:10) So Sibusiso gets 4, Dorris gets 6 and Freddy gets 10

The gross income of Ginger Hughes is $215 per week. Her deductions are: $15.16, FICA tax; $29.33, income tax; 2% state tax; 1% c
Anika [276]
215 - 44.49  (I added the two deductions mentally) = 170.51

I see the percentages 2%, 1% and 3% add up to 6%
So we want 6% of 215 or .06 x 215 = $12.90

$170.51 - 12.90 = $157.61 net income.
