The student population of a school consist of 300 girls and 500 boys. If 53% of the girls play sports, and 39% of the boys play
Ymorist [56]
Hello!

Convert the percentages to decimals by dividing them by 100, and then multiply them by the amount of boys and girls.

53 ÷ 100 = 0.53 as a decimal

0.53 × 300 girls = 159

This means that 159 of the 300 girls play sports.

Repeat this to calculate how many boys play sports.

39 ÷ 100 = 0.39

0.39 × 500 = 195

This means that 195 out of the 500 boys play sports.

Final Answer:

More boys play sports than girls.

Make t the subject of the formula.<br><br> Please help.
Digiron [165]

Answer:

t = \frac{2-3q}{q+4}

Step-by-step explanation:

q = \frac{2-4t}{t+3}\\\\

Cross multiply,

q(t+3) = 2 - 4t        

Use distributive property: a*(b + c) =(a*b) + (a*c)

qt + 3q = 2- 4t

qt + 4t + 3q = 2

  qt + 4t     = 2 - 3q

    t(q + 4)  = 2 -3q

               t = \frac{2-3q}{q+4}

How can you describe the line that passes through (0,3) and (-1, 0)​
julia-pushkina [17]

let's find the equation of line passing through those two points.

slope of the given line :

  • \dfrac{y_2 - y_1}{x_2 - x_1}

  • \dfrac{3 - 0}{0 - ( - 1)}

  • \dfrac{3}{ 1}

  • 3

now, let's plug the value of slope (m)

and y - intercept (c) in general equation

of line in slope intercept form.

i.e y = mx + c

so, we get the equation of given line as :

  • y = 3x + 3
