Mathematics
1 answer:
telo118 [61]3 years ago

Answer:

1. 4.5 g

2. 56.25 g

Step-by-step explanation:

3 % substance solution means :

3 g of dry substance is present in 100 g of solution.

By unitary method:

The weight of dry substance in 1 g of solution = \frac{3}{100}

The weight of dry substance in 150 g of solution = \frac{3}{100}\times150=4.5\ g

Let the weight of solution be w.

8 % solution contains 8 g dry substance in 100 g.

We have to find the weight of the solution(w) which contains 4.5 g of dry substance.

⇒ \frac{8}{100}\times w=4.5\\w=\frac{450}{8}=56.25\ g.

The coordinates of three vertices of square ABCD are A(−212,112),B(−212,−3), and C(2,112).
Lady_Fox [76]

Answer:

<em>P=760</em>

Step-by-step explanation:

Three of the coordinates of the square ABCD are A(-212,112) B(-212,-3) C(2,112). The image below shows the square is not ABCD but ABDC. In fact, this is not a square, as we'll prove later.

Note the x-coordinate of A and B are the same. It means this side is parallel to the y-axis. Also, the y-coordinate of A and C are the same, meaning this side is parallel to the x-axis. The missing point D should have the same x-coordinate as C and y-coordinate as B, i.e. D=(2,-3).

This shape has sides that are parallel to both axes.

To calculate the perimeter we find the length of two sides.

The distance from A to B is the difference between their y-axis:

w=112-(-3)=115

The distance from A to C is the difference between their x-axis:

l=2-(-212)=215

It's evident this is not a square but a rectangle. The perimeter is

P=2w+2l=330+430

P=760
