300 is what percent of 1200

Nadya [2.5K]

Two ways:

$\frac{300}{1200}$ = $\frac{1}{4}$ and 1/4 = 25%

Another way.

300 = n% of 1200
Problem - we can't move n% back two place to change it to a decimal since we don't know what n is. Solution - move the decimal back on the 1200 two places because since of means x, it doesn't matter. Sample .45 x 32 = 45 x .32 Notice that the decimal can be place on either number and it results in the same answer.

So 300 = 12n (1200 moved back 2 places)
now divide by 12
300 = 12n
12 12 and once again n=25(%)

A parabola is given by the equation y = x2 + 4x + 4.

notsponge [240]

Answer:

the vertex of the parabola is:(-2,0)

the focus of the parabola is:(-2, $\frac{1}{4}$ )

the directrix of the parabola is:y= $\frac{-1}{4}$

Step-by-step explanation:

we know that for any general equation of the parabola of the type $y=ax^{2} +b x+c$ the vertex of the parabola is given by (h,k)

where $h=\frac{-b}{2 a}$ and $k=\frac{4 a c-b^{2} }{4a}$

therefore by the given data we have h=-2 and k=0

hence vertex=(-2,0)

the general equation of the parabola of the type $4 a (y-h)=(x-k)^2$ ; the parabola symmetric around the y-axis has the focus from the centre i.e. the vertex (h,k) at a distance a as (h,k+a) and the directrix is given by y=k-a

so focus is $(-2,\frac{1}{4} )$

now the directrix of the parabola is $y=\frac{-1}{4}$ .

tinku is fond of collecting spiders and insects. He knows spiders have 8 legs and insects have 6 legs. he counted 36 legs. How m

kvasek [131]

Let, number of spiders = x
number of insects = y

6x + 8y = 36

remember, legs can't be in fraction or decimal.

So, only (3, 2) fits with that.

So, there are 3 spiders & 2 insects in his collection.

Hope this helps!
