Answer:
441
Step-by-step explanation:
The ratio of sidelengths squares is the ratio of the areas, so the ratio of the area of the smaller triangle's area to the larger triangle's is 25:49.
Using ratios, you figure out that the area of the larger triangle must be 225/25 *49, which is equal to 9*49 = 441
Answer:
33 1/3
Step-by-step explanation:
7/21=1/3
1/3*100=100/3
100/3=33 1/3
D is the correct answer.
When you add fractions, the answer is always rational.
1/5+-2/3= 3/15-10/15 = -7/15
A B and C are all irrational because they are nonterminating and nonrepeating decimals, which cannot be represented as a ratio of two integers. When you add a fraction to an irrational number, the result is still irrational.
7x+4 is the solution.
