check the picture below on the top side.
we know that x = 4 = b, therefore, using the 30-60-90 rule, h = 4√3, and DC = 4+8+4 = 16.
now, check the picture below on the bottom side.
since we know x = 9, then b = 9, therefore DC = 9+6+9 = 24, and h = b = 9.
Answer:
the number are 17 and 20
Step-by-step explanation:
we know that 10 is smaller than 17 so we can say the sum of both numbers is 27. thus the number satisfy the given question

Look at the three on line A and then looks at the four on line B they’re both facing the same way.
Answer:
You have a 50% chance of picking a multiple of 3.
Step-by-step explanation:
If we include 1 and 24 as factors of 24, then the possible choices would be:
1, 2, 3, 4, 6, 8, 12, 24
Of those, the only ones that are multiples of 3 are 3, 6, 12 and 24. Meaning that the chance of getting a multiple of 3 is 4/8, or 1/2, i.e. 50%
If we don't include 1 and 23, then we have:
2, 3, 4, 6, 8, 12
and 3, 6 and 12 are divisible by 3.
Which again gives 1/2, or 50%
So regardless of whether 1 and 24 are included, the chance of picking a multiple of three from the factors of 24 is 50%.
Answer:
Step-by-step explanation:
1) Number of white chocolate bars = x
Number of dark chocolate bars = y
Total bars = 15
x + y = 15 --------------(I)
Total cost = Php. 340
20x + 25y = 340 ----------------(II)
2) We can use elimination method to solve this equations.
Multiply equation (I) by (-20) and then add the equations.
(I)* (-20) -20x -20y = - 300
(II) <u>20x + 25y = 340 </u> {Now add and x will be eliminated}
5y = 40
y = 40/5
y = 8
Substitute y = 8 in equation (I)
x + 8 = 15
x = 15 - 8
x = 7
3) Number of dark chocolate bars = 8
