Yes, you are correct on 6 and 7.
#8: A standard number cube has six sides (numbers 1 through 6). There is only one 5, therefore,

would be the fraction.
#9:The spinner having three sides. Pretend there are only two sides, the red and white [2]. Again having three side, the fraction would be [/tex]\frac{2}{3} [/tex]. I apologize if I explained this one a little weird. Need anymore help or have any questions? Message me or just comment. Hope I helped a little.
Answer:
Step-by-step explanation:
you have to find the area of each side
for the two triangles(front and back sides) A=BH/2 so 45 but since there are two triangles you multiple by 2 so 90
For two rectangular sides(the ones on the sides) A=LW so 144.2 but there are two so 288.4
For the bottom rectangle A=LW so 140
Then add them together
90+288.4+140= 518.4
Answer:
(a) 
(b) 
(c) 
Step-by-step explanation:
Given
Variation: Direct
Represent ear pressure with p and depth with d.
So, we have:

when 
Solving (a): Write a variation
We have:

Write as an equation

Where: k is the constant of variation
when 
So, we have:

Make k the subject


Substitute 0.43 for k in 

Solving (b): Pressure at 50 feet
Substitute 50 for d in 


The pressure is 21.5 pounds per square
Solving (c): The safe depth
The safe depth stops at a pressure of 65psi.
Substitute 65 for p in 

Make d the subject


-- approximated
<em>The safe distance for an amateur is 151.163ft</em>
A. 12
B.8
C.8
D.16
