At least means that we need to use $\geq$

So if x is how much a sack of potatoes weight, then our inequality will be

$x \geq 20$

An aluminum rod 0.500 m in length and with a cross-sectional area of 2.20 cm2 is inserted into a thermally insulated vessel cont

netineya [11]

Answer:

a). V $_{He}$ = 14.6208 litres : b). = 0.29844 Litres/sec

Step-by-step explanation:

a).

Step 1.

Volume when one half of rod is inserted = (50/2)*(2.2) = 55cm³

Step 2.

As we know that,

V $_{He}$ = (ρV $_{c}$ IΔT) $_{Al}$ / (ρL $_{v}$ ) $H_{c}$ where $H_{c}$ = 290 - 4.2 = 285.8K

sepecififc heat of aluminum = 0.215 cal/g

density = 2.7 g/cm3

= (2.7)*(55)*(0.215)*(285.8) / (0.125)*(20900)*(1/4186)

V $_{He}$ = 14.6208 litres

b).

Step 1.

As we know that

P = kA(dT/dx) = 31*2.2*[(290-4.2)/25]

= 779.6624 W

Step 2.

Now, approximate boil rate of helium is:

P/ρL $_{v}$ = [(779.6624)*(10^3g/kg)] / [(0.125)*(20900)]

= 0.29844 Litres/sec

Please help me with this thanks

If x = 1, then 3*1 = 3 which when modded with 5, we get 3 as a remainder. In other words, 3/5 = 0 remainder 3. We don't use the quotient at all when it comes to modular arithmetic. All we care about is the remainder.

If x = 2, then 3*2 = 6 which leads to remainder 1 when we divide by 5. Therefore, 3x = 1 (mod 5) when x = 2.

If x = 3, then 3*3 = 9 = 4 (mod 5) because 9/5 = 1 remainder 4.

So 3x = 4 (mod 5) when x = 3.

<h3>The final answer is C) 3</h3>

We don't need to check D since x = 3 is a solution and it's smaller than x = 4.

If you wanted to check x = 4, then 3*4 = 12 = 2 (mod 5) because 12/5 yields a remainder of 2.

Here is a little tip for this: The unit above cancels the unit below. So in this problem you are asked to convert pounds to ounce. So your equation will look like this.

ounce = 2.93 pounds $( \frac{16 ounces}{1 pounds} ) = 46.88$
Your ratio should involve the conversion factor. So 16 and 1 is involved canceling A and D. Then, Notice that you started with poubls. Then the ratio must have pounds at the bottom to cancel the units leaving ounces.
