Hello!

This is a right triangle therefore we can use the Pythagorean theorem.

The Pythagorean theorem is $a^{2} + b^{2} = c^{2}$

c is the hypotenuse which is the side across the right angle

a and b are the other sides

Put in the values we know

$24^{2} + 7^{2} = c^{2}$

square the numbers

$576 + 49 = c^{2}$

Add

$625 = c^{2}$

Take the square root of 625

25 = c

The answer is 25

Hope this helps!

Two important ingredients for baking bread are yeast and flour. To make a loaf of bread of at most 30 servings, maintain a yeast

IceJOKER [234]

Answer:

If 0.25 oz of yeast is used, then 50oz of flour is needed.

It would require 0.5 oz of yeast for 90 oz the flour.

Step-by-step explanation:

We know that the proportion of yeast (y) and flour (f) is 1: 200 when a maximum of 30 servings of bread is made. This is:

$\frac{y}{f} = \frac{1}{200}$

So if we use 0.25 oz of yeast:

$y = 0.25\\\\y = (f)\frac{1}{200}\\\\0.25 = (f)\frac{1}{200}\\\\0.25 * 200 = f\\\\f = 50\ oz$

if 0.25 oz of yeast is used, then 50oz of flour is needed.

If you make 60 servings of bread with 90 oz. Of flour, then you should keep the following ratio:

$\frac{y}{f} =\frac{1}{180}$

So, if we use f = 90 0z of flour:

$f = 90\ oz\\\\f = 180y\\\\90 = 180y\\\\y = \frac{90}{180}\\\\y = 0.5\ oz$

It would require 0.5 oz of yeast.

<u>Given</u>

Had 200 pesos originally
spends 'y' pesos on a notebook
Bought 4 colored pens with the rest of the money

<u>Solving</u>

Let money of the pen = x, money of notebook = y
4x + y = 200
4x + 80 = 200
4x = 120
x = <u>30 pesos</u>

A rectangular piece of land to be developed as a memorial park has an area of 75 m^2. The length of the lot is three times the w

Lelechka [254]

Let length = l

width = w

length = 3 times width = 3w

Area of the land = 75 sq. m

Area = length × width = 3w×w = 75

3w²=75

w²=25

w=5 m

length = 3×15 = 15m

Now lets make the figure with the path of width x meters

(Refer the attached figure for easy understanding)

The inner length is the length of the rectangle reduced by x meters on either side due to the path

that is 15-x-x = 15-2x

the inner width is the width reduced by x meters in either side

= 5-x-x = 5-2x

Now lets calculate the inner area = inner length × inner width

(15-2x)×(5-2x)

= $75-30x-10x+4x^{2}$

= $75-40x+4x^{2}$ sq. m

Now the function to calculate the cost

f(x) is given by $3.00 × area of the inner land

f(x) = 3 × {75-40x+4x²)

= 225-120x+12x²

or

= 12x²-120x+225
