The length of a diagonal of a square is 72cm. find the length of the sides of the square​

Mathematics
1 answer:
vredina [299]2 years ago
8 0

Answer:

The answer would be 36\sqrt{2\\\\} or 50.91

Step-by-step explanation:

The way you would do this is that the diagonal of the square creates two right triangles. Both of the triangles created are 45, 45, 90 triangles.

In all cases of the 45,45,90 triangles the sides are 1/2 \sqrt{2\\\\}  of the hypotenuse aka the diagonal.  

So to solve, you would just multiply the diagonal by 1/2 \sqrt{2\\\\}  and you have your answer.

Across which axis was point A reflected​
Snezhnost [94]

Answer:

When point A with coordinates (0, -1) is reflected across the x-axis and mapped onto point A', the coordinates of A' will be (0, 1).

i.e A'(0, 1) is the image of point A after a reflection.

Hence, point A is reflected across the x-axis.

Step-by-step explanation:

When we reflect a point A across the x-axis, the value of 'y' gets negated, but the value of 'x' remains unchanged.

In other words, when point P with coordinates (x, y) is reflected across the x-axis and mapped onto point P', the coordinates of P' will be (x, -y).

Thus, the rule is:

P(x, y) → P'(x, -y)

Thus, when point A with coordinates (0, -1) is reflected across the x-axis and mapped onto point A', the coordinates of A' will be (0, 1).

i.e A'(0, 1) is the image of point A after a reflection.

Hence, point A is reflected across the x-axis.

A Copy of machine produces 80 copies in 5 minutes. How many copies would be produced in 40 minutes?
BlackZzzverrR [31]
The answer would be 640. To find the number of how many copies are produced in 1 minute you have to write 80 divided by 5 which equals 16. Now you multiply 16 and the 40 minutes which gives you 640 copies.
