Answer:
10a: △ABC is an Equilateral triangle with all acute angles.
10b: △BCD is A scalene triangle with all acute angles.
10c: △BDE is An Isosceles triangle with one obtuse angle.
Step-by-step explanation:
10) Looking at the diagram at the bottom left;
- △ABC has 3 equal internal angles and as such, it means it will have 3 equal angles.
Thus, we can classify it as; Equilateral triangle with all acute angles.
- △BCD has 3 unequal angles. Thus, it's 3 sides are not equal. Also all the angles are less than 90°.
We can classify it as;
A scalene triangle with all acute angles
- △BDE has 2 equal angles and one angle greater than 90°. This means it has 2 equal sides.
Thus, we can classify it as;
- An Isosceles triangle with one obtuse angle.
Answer: A
Explanation: It’s A because 28,500 - 23,700 = 4,800. 4,800 / 3 = 1,600. 23,700 - 4,800 = 18,900 - 1,600 = $17,300. Hope this helps :)
Let's say x=cherries and y=grapes. (desmos only does x and y :( ).
the equation would be 9=4x+1.50y
Answer:
P(not brown) = 0.60
Step-by-step explanation:
You add all of them, then you subtract the amount of brown marbles.
