840,000 is closer to 800,000 than 900,00. Therefore the answer is 800,000
1st rock = 19.28 grams
2nd rock = 25.30 grams
3rd rock = 46.3 grams
Add 1st and 2nd rock to get the combined mass
19.28 + 25.30 = 44.58 combined mass of 1st and 2nd rock
Subtract:
3rd rock mass - combined mass of 1st and 2nd rock
46.30 - 44.58 = 1.72 grams
1.72 grams greater was the mass of the 3rd rock than the combined mass of the two rocks.
Answer:
You should remove parentheses to make it in radical form
Step-by-step explanation:
Answer:
We see that the big triangle is an equilateral triangle, so all its angles will measure 60°. Therefore x° will be 60° - 30° = 30°, as he's the base angle of an isosceles triangle having the other base angle of 30°. y will simply be 180° - 60° (remembering that the sum of the angles in a triangle is always 180°).
