The correct answer is C: Families in the neighborhood that do not use the pool.

Tamiku [17]3 years ago

Answer: A) All of the families in his neighborhood

Step-by-step explanation:

A) Polling every household in the neighborhood will provide an accurate statistic of those that use the pool, those that do not use the pool, and their finances.

B) This limits the survey to only those who are using the pool on Saturday.

C) This limits the the survey to only those who do not use the pool.

D) 10 families from each of the 20 neighborhoods would be a random selection but there isn't enough information provided to determine if this covers the entire neighborhood or only a portion of the neighborhoods (since it states the 20 closest to him) or if 10 families is a sufficient percentage of the neighborhood population.

Which of the following have two congruent parallel bases? Check all that apply. A. Cone B. Circle C. None of these D. Cylinder E

koban [17]

Answer: D. cylinder F. prism

Step-by-step explanation:

From the given figures in the options , only cylinder and prism have two congruent parallel bases.

A cylinder is a solid figure which has the two congruent parallel bases i.e. circles.

A prism is a solid shape that has two parallel congruent sides which are called bases and they are joined by the lateral faces that are parallelograms.

Rest of other options do not have congruent parallel bases.

the boundary of a rectangular farm field in ireland has a straight rock wall along one side and fences along its other three sid

Inessa [10]

Answer:

781250 $ft^{2}$

Step-by-step explanation:

Let y is the length of the farm field

Let x is the width of the farm field

Given that, no fencing is necessary along the rock wall, so we can find the perimeter of the farm is:

2x + y = 2500 feet

<=> y = 2500 -2x

The are of the farm has the following formula:

A = x*y

<=> A = x(2500 - 2x)

<=> A = 2500x -2 $x^{2}$

To have the maximum area of field in square feet, we need to use differentials to estimate:

$\frac{dA}{dx}$ = 2500 - 4x

Set $\frac{dA}{dx}$ = 0, we have:

2500 - 4x = 0

<=> x = 625 feet.

=> y = 2500 - 2*625 = 1250 feet

So the maximum area of field is:

A = x*y = 625*1250 = 781250 $ft^{2}$

<h2>Required Answer :-</h2>

Given system of linear equations are ,

x + y = 2
-3x + y = 2

And we need to find the Solution of the linear equation . So let's Firstly number the equations .

$\large{\red{\frak{ Given}}}\begin{cases} \sf x + y = 2\qquad ..........(i) \\\\\sf -3x + y = 2 \qquad ..........(ii) \\\end{cases}$

→ Multiplying equⁿ (i) by 3 ,

=> 3 ( x + y ) = 2*3

=> 3x + 3y = 6

→ Adding the two equations ,

=> 3x + 3y -3y + y = 6 + 2

=> 4y = 8

=> y = 8/4

=> y = 2

→ Put y = 2 in (i) ,

=> x + y = 2

=> x + 2 = 2

=> x = 2- 2

=> x = 0

<h3>★ Hence the required solution is ( 0 , 2 ) .</h3>
