In a school 30% of year 10 students are boys. Of these 25% chose to take PE GCSE. Given there are 240 students in year 10 how ma

Arada [10]

So there are 240 students in the class

And if 30% are boys that means

$\frac{30}{100} \times 240 = 72$

so out of the 72 boys if 25% take it

$72 \times \frac{25}{100} = \frac{72}{4} = 18$

Ans: 18 boys take PE GCSE

Try this solution:
rule: the volume of any cylinder can be calculated with formula: V=πr²h, where r - the radius of the base, h - height of the cylinder.
Using the formula written above:
5. V=π*25*6=150*3.1415≈471.2389≈471.2 cm³;
6. V=π*64*4=256*3.1415≈804.2477≈804.3 cm³

What are the x- and y-intercepts of −6x+4y=96 ?

ankoles [38]

* intercepts "x" --> y=0

-6x + 4(0) = 96
-6x = 96
x = $- \frac{96}{6}$

x = 16

(16,0)

*intercepts "y" --> x=0

-6(0) + 4y = 96
4y = 96
y = $\frac{96}{4}$

y = 24

(0,24)

padilas [110]

Answer:

See the attached graphic

Step-by-step explanation:

1. Defense cards could be identify with x and offense cards with y.

2. Find the proportion:

For every 4 defense cards (y), he owns 2 offense cards (x)

Offense cards (x) Defense cards (y)

2 4

3 6

4 8

If Chad has 4 offense cards, then he owns 8 Defense cards. Note that the proportional relationship between defense cards and offense cards is 2:1. In a mathematical expression:

$y=2x$

3. Graph: See the attached graphic. Where y-axis (vertical) represents the defense cards and x-axis (horisontal) represents the offense cards.
