How do you write ten thousandths as a decimal

Help me out with this question please!

Answer:

1) Length of BC + Length of DE = 17 cm

2) The perimeter of the shape ABCDEF is 58 cm

Step-by-step explanation:

1) The given parameters are;

The length of the rectangular sheet of paper = 17 cm

The width of the rectangular sheet of paper = 12 cm

Therefore, we have;

The length of the side of the cut out square piece = DE = CD

By the definition of a square, the length of all sides of the square are equal

The length of BC + The length of one side of the square = The length of the rectangular paper = 17 cm

The length of BC + The length of one side of the square DE (or CD) = 17 cm

2) The perimeter, 'P', of the shape ABCDEF is given as follows;

P = Length of AB + Length of BC + Length of CD + Length of DE + Length of EF + Length of FA

Therefore, we have;

P = Length of AB + Length of BC + Length of DE + Length of CD + Length of EF + Length of FA

Length of BC + Length of DE = 17 cm

Similarly, we have;

Length of CD + Length of EF = 12 cm

∴ P = Length of AB + 17 cm + 12 cm + Length of FA

P = 12 cm + 17 cm + 12 cm + 17 cm = 58 cm

The perimeter of the shape ABCDEF = P = 58 cm.

an older person is 3 years older than eight times the age of a younger person the sum of their ages is 48 what are their ages

lubasha [3.4K]

Let the age of the older person be x, and the age of the younger y.

"An older person is 3 years older than 8 times the age of a younger" can be represented by the equation x = 8y + 3
"The sum of their ages is 48" can be represented by x + y = 48

We can now create a system:
x = 8y + 3 (1)
x + y = 48 (2)

Let's use the value of x in the equation (1) in equation (2) to find the value of y:
x + y = 48
8y + 3 + y = 48
9y + 3 = 48
Subtract 3 from each side to have the variables on a side and the numbers on the other:
9y + 3 - 3 = 48 - 3
9y = 45
Divide both sides by 9 to get y alone on a side and its value on the other side:
(9y)/9 = 45/9
y = 5

Let's replace y by it's value in the equation (1) to find x:
x = 8y + 3 = 8*5 + 3 = 40 + 3 = 43.

So the older person is 43 years old, and the younger person is 5 years old.

You can recheck your answer (very important):
x + y = 43 + 5 = 48 (The sum of their ages is 48)
8y + 3 = 8*5 + 3 = 43 = x (an older is 3 years older than eight times the age of a younger)
The answer has been approved.

Hope this Helps! :)

For a treasure hunt game 300 balls are hidden.of 30% of the balls that are hidden 40% of them are yellow and the rest are white.

dexar [7]

Answer:

Sally's team found 50 balls

Step-by-step explanation:

300 balls are hidden.

300x30%x40%

=36 balls are yellow

Sally's team finds 20% of 36 and 80% of the white balls (300x30%-36).

20%x36+80%x(300x30%-36)

=7 (approximately or else they would've found 7.2 yellow balls) +80%x(90-36)

=7+43 (approximately)

=50
