Answer:
A. 6 cm
Step-by-step explanation:
A P E X
V = 25,364.4 cm^3 Is volume
r = 2.7g/cm^3 Is density
To calculate mass you use formula:
m= V*r
To avoid remembering this formula you can see the type of unit on each given variable. We can see that we have g/cm^3 and cm^3. If we multiply them, we negate cm^3 and cm^3 and we are left with g which is unit for mass.
m = 68,486,6 g is the answer.
Answer: 101.08
Step-by-step explanation:
10 pens cost 144.40
1 pen will cost 144.40 /10
7 pens will therefore cost 144.40 / 10 x 7
= 101.08
Put together they will make a 90 degree angle so 15x+8x -2= 90 combine like terms you get 23x-2=90 +2= 92= 23x now 92/23 is 4 so x= 4
