Answer:
The dimensions of the park is 18yd by 18yd
Step-by-step explanation:
A square-shaped park has an area of 324 yd.
A square is composed of equal length dimensions so if the area is 324 yd² ,the dimensions or length if one side of the square will be the root of 324 yd².
Length= √324
Length= 18 yd
Dimensions of the park is 18 yd by 18 yd
Step-by-step explanation:
3 1/2 = 7 /2
2 1/2 = 5 /2
7/2 - 5/2
= 2/2 = 1

Answer:
b) 690 - 7.5*t
c) 0 < t < 92s time (t) is independent quantity
d) 0 < s < 690ft distance from bus stop (s) is dependent quantity
e) f(0) = 690 ft away from bus stop , f(60.25) = 238.125 ft away from bus stop
Step-by-step explanation:
Part a - see diagram
part b
initial distance from bus stop s0 = 690 ft
distance covered = 7.5*t
s = s0 - distance covered
s = 690 - 7.5*t = f(t)
part c
s = 0 or s = 690
0 = 690 -7.5*t
t = 92 s
Hence domain : 0 < t < 92s time (t) is independent quantity
part d
s = 0 or s = 690
Hence range : 0 < s < 690ft distance from bus stop (s) is dependent quantity because it depends on time (t)
part e
f(0) is s @t = 0
f(0) = 690 ft away from bus stop
f(60.25) is s @t = 60.25
f(60.25) = 690 - 7.5*60.25 = 238.125 ft away from bus stop.
Answer:
B
Step-by-step explanation:
Converting it to z, we can use the formula of z-score:
z-score = 
Where
x is the value we are checking for (here, x = 79)
is the mean, which is 85
is the standard deviation, which is 4 now
<em>Let's plug the information into the formula and solve for the answer:</em>
<em>

<em>B is the correct answer.</em>
Answer:
1.
90+27
2.
90 = 9 x 10
3.
27 = 9 x 3
4.
So apply the distributive property would be:
90 + 27 = 9(10 + 3)
That would be it i'm sure glad to help
