25% of what number is 3

Mathematics
1 answer:
Dovator [93]4 years ago
6 0

Answer:

12

Step-by-step explanation:

25% of what number is 3

25% goes into 100...4 times.

Then 4 times 3 equals to 12.

If you want to check, you would do 25% of 12.

and that would equal 3.

You inherit one hundred thousand dollars. You invest it all in three accounts for one year. The first account pays 4% compounded
77julia77 [94]
Let x = amount invested in the 1st account
      y = amount invested in the 2nd account
      z =  amount invested in the 3rd account

Because the total investment is $100,000, therefore
x + y + z = 100,000             (1)
Interest earned in one year from the accounts is $3,650, therefore
0.04x + 0.03y + 0.02z = 3,650
or
4x + 3y + 2z = 365,000      (2)

Because x = 5y, therefore obtain these 2 equations:
5y +y +z = 100,000
or
6y + z = 100,000          (3)
4*(5y) +3y + 2z = 365,000
or
23y + 2z = 365,000      (4)

Substitute z=1000,000 - 6y from (3) into (4).
23y + 2(100,000 - 6y) = 365,000
23y + 200,000 - 12y = 365,000
11y = 165,000
  y = $15,000
Therefore
  x = 5y = $75,000
  z = 100,000 - 6y = $10,000

Answer:
The amounts invested are
1st account: $75,000
2nd account: $15,000
3rd account: $10,000

What is the perimeter of parallelogram WXYZ
Tomtit [17]

Answer:

Step-by-step explanation:

Given a parallelogram with points

X(4, 0)

W(0, -1)

Y(3, -2)

Z(-1, -3)

We want to find the perimeter, perimeter is the total sum of the lengths

So, we need to find the length of the sides using distance between two points

D = √(x2-x1)² + (y2-y1)²

So, applying this

WX = √(0-4)²+(-1-0)² = √(16 + 1) = √17

XY = √(4-3)² + (0--2)² = √(1+4) = √5

Since the opposite sides of a parallelogram are equal, we don't need to find the other length

Then,

Perimeter = 2(WX + XY)

Perimeter = 2(√17 + √5)

Perimeter = 2√17 + 2√5

The correct answer is B.
