The fractional part that Alison is still missing is <u>3/10</u>.

<h3>What is a fraction?</h3>

A fraction is a part of an absolute value or number.

Fractions are always less than one.

Fractions are denoted by a numerator (upper part or dividend) less than the denominator (the lower portion known as the divisor).

There are proper and improper fractions.

The fraction found under the coffee table = 3/10

The fraction found under the couch = 4/10

The total fractional part found so far = 7/10 (3/10 + 4/10)

The fractional part that Alison misses = 3/10 (1 - 7/10)

Thus, Alison still misses <u>3/10</u>, which is fractionally 30% of the puzzle pieces.

A canoe requires 8 hours of fabrication and a rowboat 5 hours. The fabrication departments has at most 107 hours of labor availa
Elina [12.6K]

Answer: A

Step-by-step explanation: Canoe → 8h →X

                                            Rowboat → 5h → Y

Fabrication department has at most 107, which means it need to be <u>less</u> than 107 hours.

This way, the amount of time to fabricate X canoes = 8X plus the amount of time to fabricate Y Rowboat = 5Y must be less than 107.

8X + 5Y < 107

Answer:

V = 24.28 in ^3

Step-by-step explanation:

The area of the base is

A =5/2 × s × a  where s is the side length and a is the apothem

A = 5/2 ( 2.13) * .87

A = 4.63275

The volume is

V = Bh  where B is the area of the base and h is the height

V = 4.63275 ( 5.24)

V =24.27561 in^3

Rounding to the  hundredth

V = 24.28 in ^3

A marble factory makes single marbles, then puts them in boxes of 10, cartons of 100, and crates of 1,000. How can the marble fa
Tju [1.3M]

Given, a marble factory makes single marbles and then puts them in boxes of 10, cartons of 100 and crates of 1000.

There are 21,650 marbles. We have to find how many boxes, cartons and crates are there.

We have to write 21,650 in the form of 1000, 100 and 10.

We can write 21,650 in the form of 1000 as, (21)(1000) = 21000

Now there (21650-21000) = 650 left.

We can write 650 in the form of 100 as, (6)(100) = 600

So there, (650-600) = 50 left.

Now we can write 50 in the form of 10 as, (5)(10) = 50.

So we can write 21,650 as,

21650 = (21)(1000)+(6)(100) + (5)(10)

So there are 21 crates, 6 cartons and 5 boxes in the marble factory package.

We have got the required answer here.
