A park is rectangular with a length of ⅔ miles. If the area of the park is 3/9 square miles, what is the width?

Zielflug [23.3K]

Answer:

Area of the rectangular park = 2/3 square mile

Let us assume the width of the rectangular park = x

Then

The length of the rectangular park = 2 2/3 * x mile

= 8x/3 mile

Then

Area of the rectangular park = Length * Width

2/3 = (8x/3) * x

2/3 = 8x^2/3

(2 * 3)/3 = 8x^2

2 = 8x^2

x^2 = 2/8

x^2 = 1/4

x^2 = (1/2)^2

x = 1/2

So the width of the park is 1/2 feet.

Write an equation for each context. Draw a model first if necessary, and make sure you define your variable and what it represen

Bad White [126]

Answer:

(a)$2248.8

(b) 14, 28, 16 and 7 candies

Step-by-step explanation:

(a) the model can be represented by the nth term of an arithmetic progression

L = a + (n-1)d

L= the amount in his account after 6 month; $12484

a= the amount in his account six month before; $1240

n = 6, being the sixth month of his deposit

d = the amount deposited monthly

12484 = 1240 + 5d:

12484-1240 = 5d

5d= 11244

d = 2248.8

(b) let the 1st box contain = x

2nd = 2x; 3rd = x + 2, 4th = 1/4(2x)

Hence; x + 2x + x +2 + 1/4(2x) = 65

4x + x/2 = 65-2

9x/2 = 63 ; 9x = 126. ; x = 14

The 5 players get in all 5 racket + 5 cans since Simon is a member

Therefore, 5r + 5c = 415

But each can cost $4,

5r + 5* 4 = 415; 6r = 415-20

5r = 395 ; r = 395/5

r = $ 79

The racket cost $79 each.

Estimate the percent of each number. 47% of 77

Anettt [7]

ANSWER

36 .19

EXPLANATION

We want to estimate

$47\% \: of \: 77$

This is the same as

$\frac{47}{100} \times 77$

$\frac{47}{100} \times \frac{77}{1}$

We multiply the numerators to get,

$\frac{3619}{100}$

We convert to decimals to get

$36.19$

Sarah is saving to buy a new phone. She needs $150, and she has already saved $63. Write an equation to model this situation. Le

goblinko [34]

Answer: 150-x=63$

Step-by-step explanation:

to solve most missing number equations using addition or subtraction its usually pretty simple

1. figure out the first number. the first number is usually the goal amount. so 150

2. were do i put x? in an equation 150-63 would equal the amount she needs. so when you subtract x from 150 you'd get 63. you already know the goal number 150 goes first and the equation equals 63 so x is going to be whats subtracted from 150

3. put it all together 150(goal)-x(unknown number)=63(the amount she already had)

4.solve 150-87=63

5.check your work 150-63=87
