to the nearest cubic yard how much top soil is needed to create a flower bed with 4 ft wide by 25 ft long by 6 in deep?

6 inches = 1/2 foot

Volume of the flower bed = 4-ft x 25-ft x 0.5-ft = 50 cubic feet

1 cubic yard = 27 cubic feet

Volume of the flower bed = 50/27 = <u>1 and 23/27</u> cubic yards, about 1.85 yd³ .

Rounded to the nearest cubic yard, that's <u>2 </u>of them.

What are simultaneous equations

Masja [62]

Answer:

Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. Each of these equations on their own could have infinite possible solutions.

What is the equation for g, which is f(x) = 2x2 + 3x − 1 reflected across the y-axis? Group of answer choices g(x) = −2x2 − 3x −

Sergio [31]

Answer:

$g(x) = 2x^2 - 3x - 1$

Step-by-step explanation:

Given

$f(x) = 2x^2 + 3x - 1$

Required

Determine g(x), if f(x) is reflected across the y axis

<em>When a function (x,y) is reflected across the y axis, the new function becomes (−x,y).</em>

<em />

In other words,

$g(x) = f(-x)$

Calculating f(-x)

$f(-x) = 2(-x)^2 + 3(-x) - 1$

$f(-x) = 2x^2 - 3x - 1$

Substitute g(x) for f(-x)

$g(x) = 2x^2 - 3x - 1$

<em>Hence;</em>

$g(x) = 2x^2 - 3x - 1$

How do I write each number as a power of the given base? <br><br>example: 49; base 7

VLD [36.1K]

$7^n=49$
we know that 7*7=49 so thus $7^2=49$
$7^n=7^2$
therefor n=2
it is written as $7^2$

An economy package of cups has 460 green cups. If the green cups are 20% of the total package, how many cups are in the package?

Oksi-84 [34.3K]

2300 cups because if 460 is 20%, multiply the 460 x 5 to get 100%
