A community park is shaped like a trapezoid with a height of 30 yd, a top base of 25yd,and a bottom base of 33yd. The park has a
Likurg_2 [28]

Answer: 819.73 yd²

<u>Step-by-step explanation:</u>

A_{trapezoid} = \frac{b_{1}+b_{2}}{2}*h

                       = \frac{25+33}{2}*30

                       = \frac{58}{2}*30

                       = 29 * 30

                       = 870

A_{circle} = \pi r^{2}

                  = π(4)²

                  = 16π

                  ≈ 50.27

Area of the park = A_{trapezoid} - A_{circle}

 = 870 - 50.27

= 819.73

Which sequence is represented by = 10 − 29 where x represents the term number and y represents the term?
lina2011 [118]

Answer:

X = 18

Step-by-step explanation:

Question: The sum of three numbers in order is 57. the equation that represents this is x (x 1) (x 2) = 57. which value of x from the set {16, 17, 18, 19} makes the equation true?

Answer: First you can use the equation to work out the value of x.

x + (x + 1) + (x + 2) = 57

Simplify the equation.

3x + 3 = 57.

Now solve the equation.

57 - 3 = 54

54/3 = 18

In short, The value of x is 18.

Micheal buys two bags or chips and three boxes of pretzels for $5.13 . He then buys another bag of chips and 2 boxes of pretzels
trapecia [35]

Answer:

So a bag of chip costs $2.39

Step-by-step explanation:

Let x = cost of a bag of chip

Let y = cost of a box of pretzel

Micheal buys two bags of chips and three boxes of pretzels for $5.13

This means

2x + 3y = 5.13 - - - - - - - - - -1

He then buys another bag of chips and 2 boxes of pretzels for $3.09

This means

x + 2y = 3.09 - - - - - - - - - - - -2

Solving equation 1 and equation 2 simultaneously and using the elimination method,

Multiply equation 1 by 1 and equation 2 by 2

2x + 3y = 5.13

2x + 6y = 6.18

Subtracting,

-3y = -1.05

y = -1.05/-3= $0.35

Put y= 0.35 in equation, x + 2y = 3.09

x + 2(0.35)= 3.09

x + 0.7= 3.09

x = 3.09-0.7 = $ 2.39

So a bag of chip costs $2.39
