Answer:
8 in
Step-by-step explanation:
RA = 4 in, RB = 2 in
oil height in A = hA = 2 in
Find oil height in B = hB
volume of oil in A = VA = π*RA² * hA
equal amount means volume of oil in B VB = VA
But VB = π*RB² * hB
so π*RA² * hA = π*RB² * hB
then
hB = hA *(RA/RB)² = 2 * (4/2)² = 8 in
Answer:
6+1x=y
Step-by-step explanation:
-just add 6 because you will only pay it once to enter the fair
-place x for the number of rides the person gets on and 1 next to it to multiply
- place Y at the end because we don't know how much the person spent
For the first one a = 2.5. For the second one m = 4. For the third one m = -4
Answer:
4
Step-by-step explanation:
0*(1/3125)+1*(4/625)+2*(32/625)+3*(128/625)+4*(256/625)+5*(1024/3125)
Equation 2 is 6 times the equation 1.
<u>Explanation:</u>
Given:
-5x - 8y = 4 -1
-30x - 48y = 24 -2
The 2nd equation can be simplified in following steps:
-30x - 48y = 24
Dividing both left and right hand side by 2. We get
-15x - 24y = 12
Dividing the equation further by 3 on both the sides. We get
-5x - 8y = 4 -3
We can see that on simplification of equation 2, it becomes same as equation 1.
Therefore, equation 2 is 6 times the equation 1.
