Whats between 0.4 and 0.5

2 answers:

8 0

There are infinitely many numbers between 0.4 and 0.5, but I'd imagine what you're asking is "what number is halfway between 0.4 and 0.5?"

Remember that trailing zeroes (the zeroes after the end of a decimal fraction) don't alter the number itself, so we can also write 0.4 and 0.5 as 0.40 and 0.50, 40 hundredths and 50 hundredths. Since 45 is halfway between 40 and 50, it makes sense that 45 hundredths - 0.45 in decimal form - is halfway between 40 and 50 hundredths.

How do you do 32y + 12y

mestny [16]

Hi there!

Answer:

=44y

*The answer must have a positive sign.*

Step-by-step explanation:

<h2>Lesson: Distributive Property</h2>

Distributive property: →→→→ $a(b+c)=ab+ac$

First, you add by the numbers from left to right.

$32+12=44$

Final answer is 44y.

I hope this helps you!

Have a nice day! :)

Find the missing side of the missing side. The length of the missing side is: ?m

WARRIOR [948]

Your answer is 76m.

a^2+b^2=c^2

57^2+b^2=95^2

3249+b^2=9025

b^2=5776

Take sqr on both sides and you get:

b=76m

A landscape architect wished to enclose a rectangular garden on one side by a brick wall costing $20/ft and on the other three s

makvit [3.9K]

Answer:

The dimensions of the garden that minimize the cost is 9.018 feet(length) and 13.528 feet(width)

Step-by-step explanation:

Let the length of garden be x

Let the breadth of garden be y

Area of Rectangular garden = $Length \times Breadth = xy$

We are given that the area of the garden is 122 square feet

So, $xy=122$ ---A

A landscape architect wished to enclose a rectangular garden on one side by a brick wall costing $20/ft

So, cost of brick along length x = 20 x

On the other three sides by a metal fence costing $10/ft.

So, Other three side s = x+2y

So, cost of brick along the other three sides= 10(x+2y)

So, Total cost = 20x+10(x+2y)=20x+10x+20y=30x+20y

Total cost = 30x+20y

Substitute the value of y from A

Total cost = $30x+20(\frac{122}{x})$

Total cost = $\frac{2440}{x}+30x$

Now take the derivative to minimize the cost

$f(x)=\frac{2440}{x}+30x$

$f'(x)=-\frac{2440}{x^2}+30$

Equate it equal to 0

$0=-\frac{2440}{x^2}+30$

$\frac{2440}{x^2}=30$

$\sqrt{\frac{2440}{30}}=x$

$9.018 =x$

Now check whether it is minimum or not

take second derivative

$f'(x)=-\frac{2440}{x^2}+30$

$f''(x)=-(-2)\frac{2440}{x^3}$

Substitute the value of x

$f''(x)=-(-2)\frac{2440}{(9.018)^3}$

$f''(x)=6.6540$

Since it is positive ,So the x is minimum

Now find y

Substitute the value of x in A

$(9.018)y=122$

$y=\frac{122}{9.018}$

$y=13.528$

Hence the dimensions of the garden that minimize the cost is 9.018 feet(length) and 13.528 feet(width)
