Answer:

x=0.04m

Step-by-step explanation:

From the question we are told that:

Diameter d=24cm

Radius r=24/2=>12cm

Igniter distance d_g=9cm

Generally the equation for depth  is mathematically given by

 r^2=4d_gx

Therefore

 x=\frac{r^2}{4d_g}

 x=\frac{12^2}{4*9}

 x=4cm

 x=0.04m

I need to do this it due tommorow
Ierofanga [76]

Answer:

14

Step-by-step explanation:

when you add all the numbers together you get 14, also where you put the line you can see that the line is a 3 and 5 minus 2 is 3. The next corner next to the 3 is 1 cm because if you look at the horizontal 2 it matches up with the horizontal 1 and 2 minus 1 is 1.

2^5/4=2^5/2^a=2^b=c please help
Rudiy27
You just need to equate the expressions to find the values for a,b and c. First, let's settle that 2^5/4=8, and 8 is 2^3. Also, an important tool here is the indicie rule:
\frac{ a^{m} }{ a^{n} } = a^{m-n}
1st expression: 2^5/4=8
2nd expression: It tells us that 2^5/2^a=2^3 (I know that this equals to 8 as all the expressions are equal therefore is the same as our first expression). Using the indicie law, this means that a=2
3rd expression: 2^b must equal to 8 as well, so b=3
4th expression: c=8 as all of the other expressions we have figured out equal to 8 
So a=2, b=3 and c=8
