Let x be the price of Tanya's item. Tanya spent 5x, because she bought 5 of them.

The cost of Tony's item is x-1.75, because the price is 1.75 less than Tanya's. He spent 6(x-1.75), because he bought 6 of them.

They spent the same amount of money, so we have

$5x=6(x-1.75) \iff 5x=6x-10.5 \iff -x=-10.5\iff x=10.5$

So, Tanya's item costs 10.5, and Tony's item costs 8.75.

In fact, we have

$10.5\cdot 5 = 52.5 = 8.75\cdot 6$

Find the volume of this object.

natka813 [3]

Well to start off, the cone. It says switch ‘’ to 3 and for r (radius), we know the diameter is 6, and the radius is half of it. So the radius is 3 in.
so far it’s 3•3..to the power of two times ‘H’ (height) the height is 10, as you can see in the picture. So the equation we have so far is:
3•3^2•10 / 3 the answer to that is 90in
For the rectangle, the volume for rectangular prisms is length • width • height
so it’s 8 • 8• 1 which equals, 64 inches.
Now all you got to do is Add both answers.
90+64 = 154 in. That’s the answer

17. Which of the following is the correct formula for finding power in a DC circuit? A. P = I2R B. P = VR C. P = IR D. P = V2I

netineya [11]

Answer:

Choice A. P = I² · R where

P is the power in the DC circuit,
I is the current through the circuit, and
R is the total resistance of the circuit.

Step-by-step explanation:

Electrical power is the rate at which the electrical force does work. So what is electrical work? That's the work $W$ that the electrical force do when it moves charges $Q$ across a potential difference $V$ :
