320

Step-by-step explanation:

Well, the volume of a pyramid is 1/3 b * h

What is the height of one of these pyramids? Well, they tell you that it's 10. What is the base? It's 6 * 8 = 48

10 * 48 * 1/3 = 160

Now multiply by 2 because there are two pyramids. One on top and one one bottom. 160 * 2 = 320

For what values of x does 25× - 5ײ-3?
dusya [7]

Answer:

X = 3, -1; B

Step-by-step explanation:

Use log properties, log 5 on both sides, log 5 of 25 is 2 that times the exponent, so 2*x = 2x, and on the other side, log 5 and base of 5  cancels. So 2x = x^2 -3, which can be solved using factoring:

x^2 -2x -3 = (x-3)(x+1) = 0, x=3,-1

A television costs $350 before sales tax is applied. The final cost of the television was $378.
lana [24]
To get the answer we can use proportion. We know that 350 its 100% and 378 its 100% + taxes.
350% ------------ 100
378% ------------ x
cross multiply now
350*x=378*100
350x=37800      /:350
x=108 
Now we see that taxes its 8%, because final price its 100% + taxes = 108%
