64% is the answer to this

S_A_V [24]3 years ago

3 0

Answer:

64 percent

Step-by-step explanation:

50 is half of 100. Multiply 50 by 2 to make it easier. Since you multiply 50 by 2, you also need to multiply 34 by 2, which would mean 64% of the barrel is full.

Round each amount to the nearest hundred to find an estimate of 9635-4891

Snezhnost [94]

Answer:

4700

Step-by-step explanation:

Rounding to 100: Look at the tenth value. If this value is greater than or equal to 5, round up. If this value is less than 5, round down.

9635 = 9600

4891 = 4900

9600 - 4900 = 4700

You can check if it's accurate by comparing it to the original.

9635 - 4700 = 4744

3x - 4y = -16<br> 2x - 4y = -8<br> what is x and y

FinnZ [79.3K]

Answer:

x = -8 , y = -2

Step-by-step explanation:

Solve the following system:

{3 x - 4 y = -16 | (equation 1)

2 x - 4 y = -8 | (equation 2)

Subtract 2/3 × (equation 1) from equation 2:

{3 x - 4 y = -16 | (equation 1)

0 x - (4 y)/3 = 8/3 | (equation 2)

Multiply equation 2 by 3/4:

{3 x - 4 y = -16 | (equation 1)

0 x - y = 2 | (equation 2)

Multiply equation 2 by -1:

{3 x - 4 y = -16 | (equation 1)

0 x+y = -2 | (equation 2)

Add 4 × (equation 2) to equation 1:

{3 x+0 y = -24 | (equation 1)

0 x+y = -2 | (equation 2)

Divide equation 1 by 3:

{x+0 y = -8 | (equation 1)

0 x+y = -2 | (equation 2)

Collect results:

Answer: {x = -8 , y = -2

A business organization needs to make up a 7 member fund-raising committee. The organization has 6 accounting majors and 7 finan

photoshop1234 [79]

Answer: 658 ways.

Step-by-step explanation:

To find the number of ways the number "r" items can be chosen from the available number "n", the combination formula for selection is used. This formula is denoted as:

nCr = n! / (n-r)! × r!

Where n! = n×(n-1)×(n-2) ... ×3×2×1.

If we have 6 accounting majors and 7 finance majors and we are to choose a 7-member committee from these with at least 4 accounting majors on the committee, then the possibilities we have include:

[4 accounting majors and 3 finance majors] Or [5 accounting majors and 2 finance majors] or [ 6 accounting majors and 1 finance major].

Mathematically, this becomes:

[6C4 × 7C3] + [6C5 × 7C2] + [6C6×7C1]

525 + 126 + 7 = 658 ways.

Note: it is 6C4 because we are choosing 4 accounting majors from possible 6. This applies to other selection possibilities.
