Answer:

975 girls

Step-by-step explanation:

To find 65% of 1500, multiply 1500 by .65 (to convert percentages to decimals, just move a decimal point over two spaces).

1500*.65=975

You can check that this answer is right with logic. Most of the students will be girls (more than 50%) and 975 makes up most of 1500.

An ice cream shop sells cones at the volume of 94.2 cubic meters they want to double the volume of the cones without changing th

marin [14]

The volume of a cone is $V=\pi r^2\frac{h}3$ where r = radius and h = height. If the cone has a volume of 94.2 cm³ (I assume you didn't mean m³ because that would be ridiculously huge) and a height of 10 cm, we can plug these values into the formula to find the radius. Don't do any rounding.

$94.2 = \pi r^2\frac{10}3 \\ 282.6 = \pi r^2 *10 \\ 28.26 = \pi r^2 \\ 8.99543738355 = r^2 \\ 2.99923946752=r$

Now we know that's going to be the radius of our new cone as well since we're keeping the diameter the same. The volume is going to be double 94.2 which is 188.4. Let's solve for the height.

$188.4 = \pi (2.99923946752)^2\frac{h}3 \\ 188.4 = \pi(8.99543738355)\frac{h}3 \\ 188.4 = 28.26\frac{h}3 \\ 565.2 = 28.26h \\\\ \boxed{h = 20, r\approx 3}$

HD Straight line graphs

Taya2010 [7]

Answer:

The equation of the sraight line 3x- y+ 6 =0

Step-by-step explanation:

Explanation:-

Given that the gradient of the function

|gradf| = 3 and point (-1,3)

Given that the slope of the line

m = 3

The equation of the straight line passing through the point(-1,3) and slope m =3

$y -y_{1} = m(x-x_{1} )$

y-3 = 3(x-(-1))

y-3 = 3x+3

3x +3-y+3=0

3x- y+ 6 =0

Final answer:-

The equation of the sraight line 3x- y+ 6 =0
