A scale drawing of a rectangular park is 5 inches wide and 7 inches long. The actual park is 250 yards long. What is the area of the actual park?
someone please anwser ASAP its due today
Answer:
Part 1
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
Step-by-step explanation:
Which expression is equivalent to: (x +9)(x+3)
a. x2 + 6x + 6
b. x2+27x+12
c. x2+ 12x+27
d. x2+ 12x + 12
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.

Factor and find the zeros k^2+7k+12
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

How do you solve 4(t+25)=4(t+50)−4(0.15t)
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:
x= -p+q+y
Step-by-step explanation:
-x on each side
y-x=p-q
-y on each side
-x=p-q-y
÷everything on both sides by ‐1
We have to divide by -1 because x can't be negative
x = -p+q+y
I really hope this is right because I don't want to let you down.

9. A water pail in your backyard has a small hole in it. You notice that it has drained a total of 3.5 liters in 4 days. What is the average change in water volume each day?
10. The price of one share of ABC Company declined a total of $45.75 in 5 days. What was the average change in the price of one share per day?
11. To avoid a storm, a passenger-jet pilot descended 0.44 miles in 0.8 minutes. What was the plane’s average change of altitude per minute?
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.
10. $

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
