An architect designs a rectangle flower garden such that the width is exactly two thirds of the length. If 310 feet of antique p

AlladinOne [14]

Width = w
height = h

so w = (2/3) * h

(The perimeter surrounding it)
2w + 2h = 310

2((2/3) * h) + 2h = 310

4h/3 + 2h = 310

10h/3 = 310

10h = 930
h = 93 feet

w = (2/3) * 93

w = 62 feet

-Dominant- [34]

It triples in size every 4 days. In 16 days it will be 3 * 3 * 3 * 3 times bigger.

3 * 3 * 3 * 3 = 81
Therefore, after 16 days, the colony will contain (81 * 150) or 12,150 microorganisms.

Tom [10]

Answer:

$\$60\ per\ hour$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x -----> the number of hours worked

y ----> the amount paid in dollars

In this problem we have a proportional variation, between two variables, x, and y

<em>Find out the constant of proportionality k</em>

For (5,300) -----> $k=y/x$ ----> $k=300/5=60\ \$/h$

For (4,240) -----> $k=y/x$ ----> $k=240/4=60\ \$/h$

For (6,360) -----> $k=y/x$ ----> $k=360/6=60\ \$/h$

The constant k is

$k=60\ \$/h$

The equation is equal to

$y=60x$

The unit rate of change of dollars with respect to time is equal to the constant of proportionality or slope of the linear equation

therefore

$\$60\ per\ hour$

The difference between the product of 6 and a number and negative two times the number

Soloha48 [4]

Will equal 8 times that same number. This is because you have 6x and are subtracting -2x. Subtracting a negative is like adding a positive.
