Answer: 1167 girls.

Step-by-step explanation:

Given : Fraction of students at a school are boys=\dfrac{4}{7}

If there are 2723 students at the school, then by using multiplication operation.

The number of boys in the school=\dfrac{4}{7}\times2723

=1556

Now, the number of girls in school= Total students- Number of boys

=2723-1556=1167

Hence, there are 1167 girls.

The value of Bulls Eye stock has decreased 8% each year for the past several years. If in 2010 the stock was worth
Ivenika [448]

Answer:

$ 32.95

Step-by-step explanation:

Cost of Stock at 2010= $ 50

Declining rate each year= 8%

We have to find cost of stock at 2015

Cost of stock after 5 years= $ 50 (1-\frac{8}{100} )^{5}

Value of stock after 5 years=  $ 50 (\frac{100-8}{100} )^{5}

Value of stock after 5 years=  $ 50 (\frac{92}{100} )^{5}

Value of stock after 5 years=  $ 32.95

Hence, the correct answer is $ 32.95

Point A is on a number line halfway between −17−17 and 55. Point B is halfway between point A and 0. What integer does the point
julia-pushkina [17]
Find A first by using formula: (a+b)/2= midpoint
so: A = [(-17)+(55)]/2
         = 36

Now find B using midpoint formula:
B: (a+b)/2 
=36+0/2
=18

One of the two solutions to the equation $5x^2 - 11x - 36 = 0$ is $x = 4$. What is the other solution?
Firdavs [7]

Following are the calculation to the given equation:

Given:

\to 5x^2 - 11x - 36 = 0

one solution:

x=4

To find:

other solution=?

Solution:

\to 5x^2 - 11x - 36 = 0\\\\\to 5x^2 - (20-9)x - 36 = 0\\\\\to 5x^2 - 20x+9x - 36 = 0\\\\\to 5x(x - 4)+9(x - 4) = 0\\\\\to (x - 4) (5x+9) = 0\\\\\to x - 4=0 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 5x+9 = 0\\\\\to x = 4 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 5x = -9\\\\\to x = 4 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x = \frac{-9}{5}\\

Therefore, another solution is "-\frac{9}{5}".
