Answer: a) 1791 seconds

b) 29701 seconds

Step-by-step explanation:

1 us gallon = 0.134 cubic foot

It takes your garden hose 20 seconds to fill your 2-gallon watering can. Converting 2 gallons to cubic foot, it becomes

2 × 0.134 = 0.268 cubic foot

a) The volume of inflatable pool measuring 3 feet wide, 8 feet long, and 1 foot deep.

Volume = 3 × 8 × 1 = 24 cubic feet

If 0.268 cubic foot = 20 seconds

24 cubic feet = (24 × 20)/0.268

= 1791 seconds

b) Volume of a cylinder is πr²h

Diameter = 13 feet

Radius = diameter/2 = 13/2 = 6.5

Volume of the circular pool is

3.14 × 6.5² × 3 = 397.995 cubic feet

If 0.268 cubic foot = 20 seconds

397.995 cubic feet = (397.995 × 20)/0.268

= 29701 seconds

1. (a) Use the integral test to show that P[infinity] n=1 1/n4 converges. (b) Find the 10th partial sum, s10, of the series P[in

scZoUnD [109]

Answer:

Step-by-step explanation:

a) $\int\limits^{\infty} _1 {\frac{1}{n^4} } \, dn\\ =\frac{n^{-3} }{-3}$

Substitute limits to get

= $\frac{1}{3}$

Thus converges.

b) 10th partial sum =

$\int\limits^{10} _1 {\frac{1}{n^4} } \, dn\\ =\frac{n^{-3} }{-3}$

= $\frac{-1}{3} (0.001-1)\\= 0.333$

c) Z [infinity] n+1 1 /x ^4 dx ≤ s − sn ≤ Z [infinity] n 1 /x^ 4 dx, (1)

where s is the sum of P[infinity] n=1 1/n4 and sn is the nth partial sum of P[infinity] n=1 1/n4 .

What is 25% 136 so I know

tigry1 [53]

It's 34.

You can either intuitively know 25% means one-fourth and divide 136 by 4

Or

Convert the percentage to a decimal and multiply. 136 * 0.25 = 34

How can you solve an equation with the variable on both sides plz help

Sergeeva-Olga [200]

I don't know if this is the right one but i hope this helps. this is how i learned it.
step 1=get variables on one side oof the equal sign by using inverse operation (add or subtract smaller variable)
step 2= get constants away from variable to the other side of the equal sign by using inverse operations (add or subtract constant)
step 3: isolate the variable using inverse operation (multiply or divide)

Mr. Loza had to stop at 7-Eleven for gas on his way to school. He bought four gallons of gasoline for $16.80. How much is the pr

mihalych1998 [28]

Answer:

Every gallon costs $4.20

Step-by-step explanation:

If you divide the money he spent and the gallons he needed, you come up with a total price of $4.20 a gallon. For the amounts of gallons he could get with $40 bucks, he would have 9.5 gallons, as you just need to divide 40 by 4.2. I hope this helps :)
