What is the most useful about mathematics for human kind?

Mathematics
1 answer:
Dominik [7]3 years ago
6 0

It's useful so when you go to the grocery store you know how much of whatever you need and you can multiply, divide, and subtract if needed. Without mathematics we wouldn't be able to calculate things. If you're a cashier for example, you need to know how to count change and count the money the person gives you. If you're a customer, you need to know how much to give the cashier and that involves mathematics. I hope this helped!!!

Find the measure of y. Polygon Angle-Sum theorems
Alchen [17]

Answer:

z = 70°

y = 103°

Step-by-step explanation:

From the picture attached,

110° + z° = 180° [Supplementary angles]

z = 180 - 110

z = 70°

Since sum of interior angles of a polygon = (n - 2)×180°

where n = number of sides of the polygon

For a quadrilateral (n = 4),

Sum of interior angles = (4 - 2) × 180°

                                     = 360°

z° + y° + 100° + 87° = 360°

70° + y° + 187° = 360°

y = 103°

Therefore, measure of the angles x = 70° and y = 103°.

Solve.<br><br> Log8 (6x) = Log8 2 + Log8 (x-4)
Romashka-Z-Leto [24]

Write both sides as powers of 8, then simplify:

8^{\log_86x}=8^{\log_82+\log_8(x-4)}=8^{\log_82}8^{\log_8(x-4)}

\implies6x=2(x-4)

\implies6x=2x-8

\implies4x=-8

\implies x=-2

However, on the left hand side, this would mean we'd have, \log_8-12, which is undefined (assuming the real-valued logarithm), so this equation has no real solution.
