Answer:
(2.25,-0.5)
Step-by-step explanation:
If you were to graph the equations, they intersect at the points 2.25, and -0.5.
Answer:
32
Step-by-step explanation:
first simplify the exponent
4^2 = 16
so u would get
2 + 16 / 2 • 5 - 10
then divide and multiply to get
2 + 8 • 5 - 10
2 + 40 - 10
then add and subtract
42 - 10 = 32
Answer:
Total weight = 70.5 kg
Step-by-step explanation:
Rectangular frame is made from 5 straight pieces of metal. One of them goes through the diagonal of the rectangle.
2 pieces form the length of the rectangular frame, hence, they have a length of 12 m each
2 pieces from the width of the rectangular frame, hence, they a length of 5 m each
To find the length of the diagonal, we can use Pythagoras Theorem:
Hypotenuse² = Base² + Perpendicular²
Hypotenuse² = 5² + 12²
Hypotenuse² = 169²
Hypotenuse = 13
Hence, the length of the piece of metal placed at the diagonal is 13cm
Find the sum of all lengths of the metal pieces.
Total length = 12 + 12 + 5 + 5 + 13
Total length = 47 m
Total weight = 1.5 × Total length
Total weight = 1.5 kg/m × 47m
Total weight = 70.5 kg
