Answer:
Mass of bread crumb is 20 times the mass of the ant..
Step-by-step explanation:
Mass of an ant =
kg
Ant carries a weight of bread crumb to its anthill.
Mass of the bread crumb =
kg
Ratio of their masses,
![\frac{\text{Mass of the ant}}{\text{Mass of bread crumb}}=\frac{4\times 10^{-6}}{8\times 10^{-5}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BMass%20of%20the%20ant%7D%7D%7B%5Ctext%7BMass%20of%20bread%20crumb%7D%7D%3D%5Cfrac%7B4%5Ctimes%2010%5E%7B-6%7D%7D%7B8%5Ctimes%2010%5E%7B-5%7D%7D)
![\frac{\text{Mass of the ant}}{\text{Mass of bread crumb}}=\frac{1}{2\times 10^{(-5+6)}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BMass%20of%20the%20ant%7D%7D%7B%5Ctext%7BMass%20of%20bread%20crumb%7D%7D%3D%5Cfrac%7B1%7D%7B2%5Ctimes%2010%5E%7B%28-5%2B6%29%7D%7D)
![\frac{\text{Mass of the ant}}{\text{Mass of bread crumb}}=\frac{1}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BMass%20of%20the%20ant%7D%7D%7B%5Ctext%7BMass%20of%20bread%20crumb%7D%7D%3D%5Cfrac%7B1%7D%7B20%7D)
Mass of the bread crumb = 20×(Mass of the ant)
Therefore, mass of the bread crumb is 20 times the mass of the ant.
Answer: the first one :-)
Step-by-step explanation:
Answer:
The answer is C: 35°
Step-by-step explanation:
The sum of all angles in a triangle is 180°
So, 180°-(60°+85°)
= 180°-145°
= 35°
m∠L = 35°
Hope it helps!
Answer:
7. one triangle
8. two triangles
Step-by-step explanation:
When you are given two sides and one of the opposite angles, you can make a determination as follows:
- If the given angle is <em>opposite the longest given side</em>, there is one solution.
- If the given angle is <em>opposite the shortest given side</em>, there may be 0, 1, or 2 solutions.
For the latter case, the possibilities for sides b, c, and angle C are ...
C > 90° . . . . . . . . no solution
(b/c)sin(C) > 1 . . . no solution
(b/c)sin(C) = 1 . . . 1 solution
(b/c)sin(C) < 1 . . . 2 solutions
(The expression (b/c)sin(C) gives sin(B), so the value must lie within the range of the sine function in order for there to be any solution.)
_____
7. The given angle is opposite the <em>longest</em> given side. There is one solution.
__
8. The given angle is opposite the <em>shortest</em> given side, so we compute
(b/c)sin(C) = (34/28)sin(20°) ≈ 0.41
This is less than 1, so there are two solutions.
