The number of boys in the schools is 104.
Step-by-step explanation:
Given,
The ratio of boys and girls is 8:9
Number of girls = 117
Let us take,
Number of boys = 8x
Number of girls = 9x
To find the number of boys.
According to the problem,
9x = 117
or, x = 
= 13
Hence, the number of boys = 13×8 = 104
Answer:
<em>The diagram to the left is not a dilation</em>
Step-by-step explanation:
If the diagram to the left is a dilation, then AB // A'B'.
Applying Thales theorem: PA/PA' = PB/PB'.
Or 2/(2+4) = 3(3+5)
Or 2/6 = 3/8, this is incorrect
=> AB and A'B' are not parallel. As a result, the diagram is not a dilation.
Hope this helps!
The number of scented candles ... x
the number of unscented candles ... y
x + y = 28
$16 * x + $10 * y = $400 ... 16 * x + 10 * y = 400
If you would like to know how many scented and how many unscented candles did the shop sell today, you can calculate this using the following steps:
x + y = 28 ... x = 28 - y
16 * x + 10 * y = 400
____________________
16 * (28 - y) + 10 * y = 400
16 * 28 - 16 * y + 10 * y = 400
448 - 400 = 16 * y - 10 * y
48 = 6 * y /6
y = 48 / 6
y = 8
x = 28 - y = 28 - 8 = 20
Result: The candle shop sold 20 scented candles and 8 unscented candles today.
