If he puts 300 sunfish into the pond, he will put 225 perch in the pond.

<h3>What is a ratio?</h3>

A ratio is the comparison of one thing to another. Generally, ratios compares value.

They store the children pond keeping a ratio of 4 sunfish to 3 perch. Therefore, the ratio of sunfish to perch will be as follows

4:3

If he 300 sunfish into the pond , the number of perch that will be in the pond can be calculated as follows:

4 / 3 = 300 / x

cross multiply

4x = 900

x = 900 / 4

x = 225

A cuboid is 4cm long, 7cm wide and 10cm high..A similar cuboid is 25cm high,calculate its length and width.....

coldgirl [10]

The dimensions of the larger cuboid are 25/10 = 2.5 times those of the smaller one. {length, width} = 2.5*{4 cm, 7 cm) = {10 cm, 17.5 cm}

The area of a rectangle garden is 2g^2+34g+140. If the width is 2g+14 what is the length?

ASHA 777 [7]

We know that
[area of rectangle]=length*width
area=2g²<span>+34g+140
</span><span>width =2g+14
</span>
step 1
find the roots of 2g²+34g+140

using a graph tool-----> to resolve the second order equation
see the attached figure
the solution is
g=-10
g=-7
so
2g²+34g+140=(2g+14)*(g+10)

therefore

the length is (g+10)

the answer is
the length is (g+10)

Differentiate <br> \[\ln \sin^2 x\]

iragen [17]

Y = ln {[sin(x)]^2}

use the chain rule

y' = 1 /[sin(x)]^2 * 2sin(x)*cos(x) = 2cos(x) / sin(x) = 2 cot(x)

Answer: 2 cot(x)
