There is a percent formula for all of these types of percent problems.

It is : is/of = %/100

224 is what % of 640
is = 224
of = 640
% = x
now just sub
224/640 = x/100
cross multiply because this is a proportion
(640)(x) = (224)(100)
640x = 22400
x = 22400/640
x = 35......so 224 is 35% of 640

Julli [10]

Answer:

225 rs

Step-by-step explanation:

cost of 1 pen = 20 rs

total cost of 4 pens = 20×4= 80 rs

cost of 1 pencil = 5 rs

total cost of 5 pencils = 5×5 = 25 rs

cost of 1 box = 60 rs

total cost of 2 boxes = 60×2 = 120 rs

Total= 80+25+120 = 225 rs

A bird drops a stick from the top of Miami Tower. The height of the stick after x seconds is given by f(x) = 625 - 16x^2.

Leni [432]

ANSWER

The maximum value is 625

EXPLANATION

The height of the stick that the bird dropped is modeled by the function;

$f(x) = 625 - 16x^2$

This function is already in the vertex form.

Let me rewrite it clearly for you to see.

$f(x) = - 16(x - 0)^2 + 625$

When we compare this to;

$f(x)=a(x-h)^2+k$

we have h=0 and k=625.

k=625 is the y-value of the vertex.

This is the maximum value on the graph of this function.
