What is 56.398 rounded to the nearest tenth?

Vesna [10]

Well when you round to the nearest 10 it will be 1 number after the point (this is due to that 10 only has one 0.) now we know that if there is a number bigger than 5 besides the number they ask you in this case the first after the point you will add 1 to that number. in this case you will add 1 to the 3. this will give you the answer of 56.4

Hope this helps

Someone help me please I'm so desperate

ludmilkaskok [199]

Answer:

126 tiles

Step-by-step explanation:

The while tiles are 3/4 of a foot (or 9 inches) x 9 in, so their area is 81 sq in. There are 14 blue tiles, so 14 x 81 = 1134 sq inches that need to be covered.

Each tiles is 3 x 3, so its area is 9 sq in. 1134 / 9 = 126 tiles

Ricky rides his bike 12 miles every day he stops 7 miles to rest write and solve an equation to find out how much further he has

kondor19780726 [428]

<h3><u>Question:</u></h3>

Ricky rides his bike 12 miles every day. He stops after 7 miles to rest. write and solve an equation to find out how much further he has to ride

<h3><u>Answer:</u></h3>

Ricky has to further ride for 5 miles

<h3><u>Solution:</u></h3>

Given that, Ricky rides his bike 12 miles every day

Let "x" be the remaining distance in miles he has to ride further

Total distance = 12 miles

Also, given that he stops after 7 miles to rest

Therefore, already covered distance = 7 miles

Therefore, we can frame a equation as,

remaining distance + already covered distance = total distance

x + 7 = 12

Solve the above equation for "x"

x = 12 - 7

x = 5

Thus Ricky has to further ride for 5 miles

The company’s cost of manufacturing a single 1-inch binder is $0.25. What is the expected profit (in dollars) that the company w

pav-90 [236]

It should be noted that the mean and the standard deviation of the data given in will be 4.26 and 1.1011 respectively.

<h3>How to solve the mean.</h3>

From the complete information, the mean will be calculated as:

= (0.02 × 1) + (0.09 × 2) + (0.12 × 3) + (0.15 × 4) + (0.62 × 5)

E(X) = 4.26

The standard deviation will be calculated thus:

E(X²) = (0.02 × 1²) + (0.09 × 2²) + (0.12 × 3²) + (0.15 × 4²) + (0.62 × 5²)

E(X²) = 19.36

The standard deviation will then be the difference between the square root of 19.36 and 4.26². This will be 1.1011.

The expected profit of the company will be:

= 0.75 × E(X)

= 0.75 × 4.26

= $3.20

The mean of the total number of binders purchased will be:

= 4.26 + 2.74 = 7

The standard deviation will be 1.6658.

Lastly, the total expected profit will be:

= 0.75E(X) + 1.45E(Y)

= 0.75(4.26) + 1.45(2.74)

= 3.195 + 3.973

= 71.68
