The number of students in a class is 60. The number of boys is seven-fifths the number of girls. Find the number of boys in the
Fynjy0 [20]

Step-by-step explanation:

Let the number of girls = x

Therefore, no. of boys = \frac{7}{5} \times x

\because \: no \: of \:  boys + no \: of \: girls \:  = 60 \\  \\  \therefore \:  \frac{7}{5} x + x = 60 \\  \\ \therefore \:  \frac{7x + 5x}{5} = 60 \\  \\  \therefore \:  \frac{12x}{5} = 60 \\  \\  \therefore \: x = 60 \times  \frac{5}{12}  \\  \\ \therefore \: x = 5 \times 5 \\  \\ \therefore \: x = 25  \\  \\  \therefore \:  \frac{7}{5} x =  \frac{7}{5}  \times 25 = 7 \times 5 = 35 \\

Thus, no of boys in the class is 35.

What is the length of stack J M with bar on top space in the rectangular prism? Round your answer to the nearest tenth.
musickatia [10]
Volume of the rectangular prism = l * w * h
Diagonal = √l² + w² + h²
                 = √ 16² + 12² + 8²
                = √464
                 = 21.5

Which of the following is the equation of the line that is perpendicular to y=−18x−2 and goes through the point (-2,-3)?
Irina-Kira [14]
Given that the equation of the line is:
y=-18x-2
the equation is in the form of y=mx+c, where m is the slope. Thus the slope of equation is -18. The line perpendicular to this equation has a slope of 1/18, hence the equation will be given by the formula:
m(x-x1)=y-y1
given that the line passes through point (-2,-3) the equation of the line will be:
1/18(x--2)=y-(-3)
1/18(x+2)=y+3
simplifying this gives us:
y=1/18x+1/9+3
y=1/18x6+3 1/9
