You want to put a 5 inch thick layer of topsoil for a new 16 ft by 34 ft garden. The dirt store sells by the cubic yards. How ma
shepuryov [24]

Answer: About 8.5 cubic yards

Step-by-step explanation:

Given : The length of the garden = 16 ft.

The width of the garden = 34 ft.

The depth of the thick layer of topsoil on the garden = 5 inch

=\dfrac{5}{12}\text{ ft.}               [Since 1 foot = 12 inches]

The volume of a rectangular prism :-

V=l*w*h, where l is length , w is width and h is height.

The number of cubic feet of topsoil required will be

V=16\times34\times\dfrac{5}{12}=\dfrac{680}{3}\text{cubic feet}

Since 1 yard = 3 feet

1\text{ foot}=\dfrac{1}{3}\text{ yard}

V=\dfrac{680}{3}\times\dfrac{1}{3}\times\dfrac{1}{3}\times\dfrac{1}{3}=8.3950617284\approx8.50\text{cubic yards}

raketka [301]

Blocks would he need on the 12th step of the pattern is 34.

The correct option is A

<h3></h3><h3>What is series?</h3>

A series is the cumulative sum of a given sequence of terms.

Given:

We can write the series as follows:

1,4,7,10,13,.......

First term =1

common difference= 4-1=3

Using Arithmetic series

a_{12}\\= a+11d

    =  1 +11*3

    = 1+33

    = 34.

Hence, 34 blocks need on 12th step.

Solve by factoring and list only the positive solution: 2x2 - 5x = 88
Semmy [17]
It has to be noted that there are several ways to factor the item. One of these is shown below. 

The general form of a quadratic equation is,
            Ax² + Bx + C = 0

where A and B are numerical coefficients and C is the constant. If we are to express the given equation in this form, 
        2x² - 5x - 88 = 0

The sum of the roots, x₁ and x₂ is -B/A and the product is equal to C/A.

Sum: x₁ + x₂ = -(-5/2) = 5/2
 Product: x₁x₂ = -88/2 = -44

The values of x₁ and x₂ are 8 and -11/2.

The factors are (x - 8) and (x + 11/2)

<em>ANSWERS: 8 and -11/2. </em>

If you have 100 entries out of 1200 what are your chances
swat32
100/1200= x/100
cross multiply

(1200 * x)= (100 * 100)

1200x= 10000
divide both sides by 1200

x= 8.333% winning chance


LOSING CHANCE
100% - 8.333%= 91.667%


RATIO OF WINNING TO LOSING
100 tickets= winning chance
1200 total - 100= 1100 losing chance

100:1100
simplify by 100

1:11 odds of winning to losing


ANSWER: The chance of winning is 8.333% and the chance of losing is 91.667% or 1:11.

Hope this helps! :)
