Step-by-step explanation:
We know that
Volume of square pyramid = a² × h/3
=> (12)² × 8/3
=> 144 × 8/3
=> 48 × 8
=> 384 in³
Now,
We need to find ratio for finding the times of the volume
=> 3456/384
=> 9
Hence,
Volume of pyramid B is 9 times greater than the volume of pyramid A
Answer:
34,879 × 10 = 348,790
Step-by-step explanation:
The answer is <em>348,790</em><em> </em>because 34,879 multipled by 10 is <em>348,790</em><em> </em>as shown in the picture above ^^
Answer:
A: 112 cubic inches
Step-by-step explanation:
A = l*w*h/3 = (6*8*7)/3
A = 336/3
Answer:
a=30 , b = 0
Step-by-step explanation:
let the two numbers be represented as a and b
a + b = 30... eqn 1
a - b = 30 ...... eqn 2
we then add the two equations to get values for a and b
a + b + a - b = 30 + 30
a + b + a -b = 60
2a = 60 ( diivide both sides by 2)
a = 30
we then put value for a = 30 into any of the equations to get b
a + b = 30, 30 + b= 30
b = 30 -30 , b = 0
to confirm if the answers are correct, we insert the values for a and b in the two equations.
a + b = 30..... eqn 1, 30 + 0 = 30
a - b = 30 ...... eqn 2 , 30 - 0 = 30
If y varies inversely with x, then we know that:
y = k/x
We are given x and y, so plug in the numbers and solve for k.
1.5 = k/6.4
k = 1.5*6.4
k = 9.6
