Answer:
If it has the little line under the > sign then x = 5
Step-by-step explanation:
The circumference of a circle of diameter 13 m is 13π m, about 40.82 m.
(40.82 m)/(2.5 m) = 16.328
16 may be the best approximation of the number of pieces Malia will need. 17 pieces will make a barrier that is longer (larger diameter) than is needed.
Answer:
y = 
Step-by-step explanation:
We are given the point (3, 10).
The second point is 2 on the x-axis and -7 on the y-axis. So our second point is: (3 + 2, 10 - 7) which is (5, 3).
Our formula for slope is m =
= 
So, our equation would be
= 
Using the standard formula of a line, y = mx + b, we can substitute for the slope, m.
y =
+ b
Now, we can substitute a point on the line to determine the y-intercept:
Using the point (3, 10),
10 =
+ b
b = 10 + 
b = 
So our full equation is: y = 
Answer:
9.8 cm
Step-by-step explanation:
Volume of a sphere, V = 4/3 πr³
V = 500cm³
π = 3.14
500 = 4/3 * 3.14 * r³
500 * 3 = 4 * 3.14 * r³
1500 = 12.56r³
r³ = 1500 / 12.56
r³ = 119.42675
r = (119.42675)^1/3
r = 4.9245574
Diameter = 2r
Diameter = 2 * 4.9245574
Diameter = 9.849
= 9.8cm
Answer:
z(195) = (195-200)/50 = -0.1
z(205) = (205-200)/50 = +0.1
P(195 < x < 205) = p(-0.1 < z < 0.1) = 0.0797
