David's last equation to solve is x/100+3/100=8/100. Write and solve an equivalent equation with easier numbers that would give

JulijaS [17]

$\sf\dfrac{x}{100}+\dfrac{3}{100}=\dfrac{8}{100}$

Subtract 3/100 to both sides:

$\sf\dfrac{x}{100}=\dfrac{5}{100}$

Cross multiply:

$\sf100x=500$

Divide 100 to both sides:

$\sf~x=5$

Or we could just multiply both sides of the equation by 100, to give us:

$\sf~x+3=8$

Subtract 3 to both sides:

$\sf~x=5$

A hot tub has capacity of 1458 liters 487 liters and 750 ml were put in how much more needs to be put in

Colt1911 [192]

Well the easiest way we can do it is convert liters in to milliliters and since there are 1000 milliliters in a liter multiply 1458 by 1000 and 487 by 1000 which will get you 1458000 milliliters of capacity and the 487 liters turns into 487000 mililiters we add this to the 750 milliliters to get 487750 milliliters. Now it is all a matter of subtracting to find out how much more needs to be put in. 1458000-487750=970250 milliliters. So the amount needed to fill the hot tub is 970250 ml or if you want to convert it back to liters 970.250 l

58 yd<br> 73 yd<br> Use 3.14 Instead Of Pie Symbol

defon

Answer:

$771096.8 \: yd^{3}$

Step-by-step explanation:

If you are trying to find the volume, you would use the formula:

$\pi \: r ^{2} (h)$

You would plug in the radius (r), which is 58, and then plug in the height, which is 73.

Make sure you remember to use 3.14 and not the pi key if you are using a calculator.

The final answer is 771,096.8 yd^3
