Answer:
see explanation
Step-by-step explanation:
Given
F = 
(K - 273.15) + 32
Multiply through by 5 to clear the fraction
5F = 9(K - 273.15) + 160 ( subtract 160 from both sides )
5F - 160 = 9(K - 273.15) ← distribute
5F - 160 = 9K - 2458.35 ( add 2458.35 to both sides )
5F + 2298.35 = 9K ( divide both sides by 9 )
K = 
(b)
When F = 180, then
K = 
= 
= 
≈ 355.37 ( to the nearest hundredth )
Answer:
1/6
Step-by-step explanation:
So for this you need to set them equal to each other! 3x+100=5x-160
now you combine like terms and solve!
Answer:
<em> 1005 girls</em>
Step-by-step explanation:
From the question we are given ratio of boys to girls as 7 : 29
Total ratio will be 7 + 29 = 36
Total students in the school = 1248 students
Number of girls in the school = 29/36 * 1248
Number of girls in the school = 29 * 35
Number of girls in the school = 1005
<em>Hence the approximate total number of girls in the school is 1005 girls</em>
<em></em>
<em>Note that the ratio was assumed since we are not given in question</em>
