Answer:
Here's one way to do it
Step-by-step explanation:
Divide the hexagon into triangles, for example, as in the diagram below.
The triangles are all inside the hexagon, so the sum of their interior angles is the sum of those of the hexagon.
The sum of the interior angles of a triangle is 180°.
There are four triangles, so
Sum of interior angles = 4 × 180° = 720°
Answer: 11
Step-by-step explanation:
If 15 workers can paint 18 houses in 24 days, how many days will 40 workers take to paint 22 houses?
--------------
# of days are inversely related to # of workers and directly related
to # of houses.
--------------
d = kh/w
---
Solve for "k" using "15 workers can paint 18 houses in 24 days"
24 = k*18/15
k = 15*24/18 = 15*(4/3) = 20
--------------
Equation:
d = 20h/w
---
Solve: How many days will 40 workers take to paint 22 houses?
d = 20*22/40
d = 11 days
2p² - p - 10 = 0
2 = a
- 1 = b
- 10 = c
To factor, find two numbers that multiply to equal a·c and also that have a sum of b
2p² + 4p - 5p - 10 = 0
2p (p + 2) - 5 (p + 2) = 0
<h3>Answer: ( 2p - 5 ) ( p + 2 ) = 0</h3>
Y+9=10
always remember that sum means addition
hope this helps <3
You need to find the GCF of both numbers. Both of these numbers have a GCF of 1 so the answer is already in simplest form. Unless you want it in a decimal which in that case you just divide. 5.34
