Use a ruler for this problem. Take a picture of the measurement & then I could help you.
Answer:
X=0 or no solution
Step-by-step explanation:
-2x+4=-3x+4
cancel equal terms on both sides of the equation
-2x=-3x
move the variable to the left-hand side and change its sign
-2x+3x=0
collect like terms
x=0
Answer:
Step-by-step explanation:
<u>In 4 seconds the rock will be at:</u>
- 2*4 = 8 in from the surface
<u>Add 5 feet to this to get the required distance:</u>
- 5 ft + 8 in = 5*12 in + 8 in = 68 in

Step-by-step explanation:
The volume of a rectangular prism (cuboid) can be figured from its dimensions, or from the base area and height:
V = LWH . . . . . volume is the product of length, width, height
V = Bh . . . . . . . volume is the product of base area and height
__
Hopefully, you recognize that these are basically the same formula, since the base area is the product of length and width.
For the given figures, the volumes are ...
A = (1/2 m)(1/4 m)(1/4 m) = 1/32m³
B = (32 m²)(7.25 m) = 232 m³
C = (1/2 m)(1/2 m)(1/4 m) = 1/16 m³
D = (3 1/2 m)(8 1/2 m)(9 3/4 m) = 290 1/16 m³
E = (26 1/3 m²)(5 m) = 131 2/3 m³
__
The volumes from greatest to least are ...
D B E C A
The z-score is given by:
z=(x-mean)/s.d
the z-score giving us P(0.95)=1.96 and -1.96
thus;
-1.96=(x-1500)/300
-588=x-1500
x=-588+1500
x=912
also:
1.96=(x-1500)/300
588=x-1500
x=588+1500
x=2,088
therefore the sample size of the student picked will be given by:
2,088-912
=1,176
