Answer:
1/10 or 3kids
Step-by-step explanation:
First you want to take 3/5 into 10nths so you do 3/5 times two and you get 6/10 then you add up 6/10 and 3/10 and you get 9/10. 30÷ 9/10 is 27 so 3 kids are having other things
Answer:
a = 16
Step-by-step explanation:
inversely proportional
y = k/x
a = k/b
5 = k/4
solve for k
multiply by 4 on each side
20 =k
a = 20b
if b = 4/5
a = 20 * 4/5
a = 16

Answer:
24179 square inches
Step-by-step explanation:
In ΔRST, r = 620 inches, s = 840 inches and t=230 inches. Find the area of ΔRST to the nearest square inch.
We use the formula
Heron's formula = √s(s - a)(s - b)(s - c)
Where s = a + b + c/2
Solving for s
s = 620 + 840 + 230/2
s = 845
Solving for the area of the triangle
= √845 × (845 - 620) × (845 - 840) × (845 - 230)
= √584634375
= 24,179.213696893 square inches
Approximately = 24179 square inches
