Answer:
A and E
When doing problems like these it is easier just to see what numbers are divisbale by the ration.
Example:
A: 21/30
21 is divisable by 7 and 30 is divisbale by 10
E: 35/50
35 is divisable by 7 and 50 is divisbale by 10
8 grams reduced by 30%....if it is reduced by 30%, then there is a total of 70%
70% of 8.....turn ur percent to a decimal..." of " means multiply
0.70 * 8 = 5.6 grams <==
10 grams reduced by 40%.....so it contains 60%
60% of 10 =
0.60 * 10 =
6 grams <==
so brand A, the 8 grams reduced by 30%, now has less fat <==
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
