sergeinik [125]

Let
x-----> distance school to the park
y-----> distance park to the house

we know that
x=1/3 mile
y=1/2 mile

[distance from school to the house]=x+y----> (1/3+1/2)
The common denominator is (3*2)---> 6
=(2*1+3*1)/(3*2)----> 5/6 mile

the answer is
5/6 miles

Suzanne wants to put a fence around her square garden. If the garden covers an area of 49ft^2, how many feet of fencing does she

lina2011 [118]

Answer:

The area for a square is given by:

$A = x^2$

And we can find the dimension for one side like this:

$x = \sqrt{A}$

Replacing we got:

$x = \sqrt{49 ft^2}= 7ft$

Then since we are interested in the how many feet of fencing does she need, we can find the perimeter given by:

$P = 4x$ and replacing we got:

$P = 4*7 ft = 28 ft$

Step-by-step explanation:

For this case we know that Suzanne want to put a fance around a square garden with an area of 49 ft^2

The area for a square is given by:

$A = x^2$

And we can find the dimension for one side like this:

$x = \sqrt{A}$

Replacing we got:

$x = \sqrt{49 ft^2}= 7ft$

Then since we are interested in the how many feet of fencing does she need, we can find the perimeter given by:

$P = 4x$ and replacing we got:

$P = 4*7 ft = 28 ft$

Suppose the population of a town is 15,200 and is growing 2% each year. Write an equation to model the population growth. Predic

larisa [96]

For this case, what you need to know is that to model this problem, you must use equations of the potential type:
y = A * (b) ^ t
Where:
A: initial population.
b: growth rate.
t: time.
Substituting values we have:
y = 15200 * (1.02) ^ t
After 10 years we have:
y = 15200 * (1.02) ^ 10
y = 18529
Answer:
An equation to model of the population growth is:
y = 15,200 ∙ 1.02 ^ x
the population after 10 years is:
about 18,529

A student needs to make a circular cardboard piece with an area between 154 square inches and 616 square inches. The function f(

Nezavi [6.7K]

The area of the circle by definition is given by:
$f (r) = \pi * r ^ 2
$
For f (r) = 154:
$154 = \pi * r ^ 2
$
Clearing r we have:
$r ^ 2 = 154 / 3.14

 r = \sqrt{154/3.14} 

 r = 7$
For f (r) = 616:
$616 = \pi * r ^ 2$
Clearing r we have:
$r ^ 2 = 616 / 3.14 r = \sqrt{616/3.14} r = 14$
Answer:
a reasonable domain for f (r) is:
7 <r <14
