If the actual park is 250 yards LONG, I think it means that its LENGTH is also 250 yards

Part 2

It's a proportion:

5=x

7=250

5*250:7=178.6 yards

The area is 178.6 yards wide and 250 yards long

Answer:

A=61.5cm^2

Step-by-step explanation:

Area= 5*1/2(lh)

A=5*1/2(6*4.1)

A=5*1/2*24.6

A=5*12.3

A=61.5cm^2

Answer: 9-11 below

Step-by-step explanation:

9. Well, we're given that the hole drains color(red)(3.5color(white)(l)"L" in color(green)(4color(white)(l)"d", so we can write the rate as

(color(red)(3.5color(white)(l)"L"))/(color(green)(4color(white)(l)"d"))

Now we perform this division, and afterward the denominator will be 1 and thus it will tell us the number of liters drained per day:

(color(red)(3.5color(white)(l)"L"))/(color(green)(4color(white)(l)"d")) = color(blue)(ulbar(|stackrel(" ")(" "(0.875color(white)(l)"L")/(1color(white)(l)"d")" ")|)

Therefore, color(blue)(0.875color(white)(l)"liters" are drained every day on average.

decrease per day

Explanation:

We can divide the total price decrease by the number of days it took to reach that decrease to find the average decrease per day:

11. The average change of altitude per minute would simply be the ratio of distance descended over time. That is:

average change of altitude = distance / time

average change of altitude = 0.44 mile / 0.8 minutes

average change of altitude = 0.55 mile / minute

Answer:

c

Step-by-step explanation:

x*x=x^2

x*9=9x

x*3=3x

9x+3x=12x

9x3=27

x^2+12x+27

Answer:

C

Step-by-step explanation:

To solve use the FOIL method, First, Outside, Inside, Last. This means to multiply the first terms, the ones on the outsides, the ones on the insides, and finally the last ones.

First, multiply x*x= [tex]x^{2}[/tex]

Then, multiply x*3= 3x

Next, multiply 9*x= 9x

Finally, multiply 9*3= 27

To simplify put all of the products together, [tex]x^{2}[/tex]+3x+9x+27, then add like terms [tex]x^{2}[/tex]+12x+27, so the answer is C.

Answer:

12.5

Step-by-step explanation:

Ruth's shadow length over her height: 3/5

The length of the shadow of the slide over the slide"s height: 7.5/x

Use these ratios to solve for x: 3/5=7.5/x = 3x = 37.5

x= 12.5

Answer:

500/3.

Step-by-step explanation:

4(t+25)=4(t+50)−4(0.15t)

4t + 100 = 4t + 200 - 0.6t

Subtract 4t from both sides

100 = 200 - 0.6t

-0.6t + 200 = 100

-0.6t = -100

0.6t = 100

6t = 1,000

3t = 500

t = 500/3, or 166.6666667, or 166 and 2/3.

Hope this helps!

Step-by-step explanation:

4(t+25)=4(t+50)-4(0.15t)

4t+100=4t+200-0.6t

4t-4t+0.6t=200-100

0.6t=100

Answer:

I'm confused to what this means

Answer:

(k+3)(k+4)

The zeros are -3 and -4

Step-by-step explanation:

k2+7k+12

The middle number is 7 and the last number is 12.

This means we need two numbers that:

Add together to get 7

Multiply together to get 12

to fit in this equation (k+_)(k+_)

in this equation, it would be 3 and 4

3+4 = 7

3*4 = 12

Now we fill in the blanks to get

(k+3)(k+4)

To get the zeros, use the equations

k+3=0 and k+4=0

You end up with

k=-3 and k=-4
