Answer:

20.5426 (rounded to nearest 0.0001)

Step-by-step explanation:

Square roots can't be really be explained, but there is one think you should know. 422 is 22 more than 400, which is greater than what would be the halfway point (20.5 ^ 2 = 420.25), so √422 is greater than 20.5, but not greater than 20.55 (20.55 ^ 2 = 422.3025). However, it is close to 20.55 though. Thus, you can conclude √422 is about 20.5426.

For the first question, all you need to know is that the (amount you want) divided by (the amount of cards total) is the probability of getting the amount you want at random. for example, if there are 3 red marbles in a bag of ten marbles, you divide 3 by 10 (0.30) the probability of picking up a red marble is 30%. try adding up how many cards you want to pick up by the number of cards total.

If gas costs $3.15 per gallon, how many whole gallons of gas could you buy with $27.00?
Volgvan

Answer: 8 whole gallons.

Step-by-step explanation: If you have only $27.00 and you need to buy gas, but each gallon is $3.15, then you just need to divide your total amount ($27.00) by your cost per gallon ($3.15), and you will get about 8.6 gallons, however this question asks for how many WHOLE gallons you can get, so all you need to do is round down to fit your budget, leaving money for only 8 whole gallons.

WORK: ($27.00) / ($3.15) = 8.6 gallons

A cylinder has a volume of 400 cubic feet. If the height of the cylinder is 25 feet, what is the radius of the cylinder? Use 3.
Lisa [10]

The radius of the cylinder will be  r=2.25ft

<h3>What will be the radius of the cylinder?</h3>

It is given that

Volume of the cylinder = 400 ft^{3}

height of the cylinder= 25 ft^{3}

Now we know that

Volume of the cylinder = \pi r^{2} h

putting values in the formula

400= \pi \times r^{2} \times25

r= \dfrac{4}{\sqrt{3.14} }

r=2.25 ft

Thus the radius of the cylinder will be  r=2.25ft
