You install 404 feet of fencing along the perimeter of a rectangular yard.
Gemiola [76]

Answer:

The length of the yard is 102

Step-by-step explanation:

If the width of the yard is 100 feet, and it's a rectangular, that means the other side of the rectangle is also equal to 100 feet. So so far we have 200 feet of the yard covered. Then we do 404-200=204. So the combined length of both the sides is 204. Since they both equal the same length, we can then do 204/2 to get 102. So one side length is 102 and the L, W, L, W of the rectangle is 102, 100, 102, 100. In other words, the rectangle is 102 by 100.

The larger of two numbers is twice the smaller increased by five. Find the two numbers if three times the larger exceeds double
irina [24]

The larger number is 13 and smaller number is 4

<em><u>Solution:</u></em>

Let the larger number be "a"

Let the smaller number be "b"

<em><u>Given that larger of two numbers is twice the smaller increased by five</u></em>

larger number = twice the smaller increased by five

larger number = twice the smaller number + 5

a = 2b + 5 --- eqn 1

<em><u>Also given that three times the larger exceeds double the smaller by 31</u></em>

Here "exceeds" denotes addition and "times" denotes multiplication

"double" denotes being multiplied by 2

three times the larger number = double the smaller number + 31

3a = 2b + 31 ---- eqn 2

<em><u>Let us solve eqn 1 and eqn 2 to find values of "a" and "b"</u></em>

Substitute eqn 1 in eqn 2

3(2b + 5) = 2b + 31

6b + 15 = 2b + 31

6b - 2b = 31 - 15

4b = 16

<h3>b = 4</h3>

From eqn 1,

a = 2b + 5

a = 2(4) + 5

a = 8 + 5

<h3>a = 13</h3>

Thus the larger number is 13 and smaller number is 4

The value of the 9 is ten times the value of the 9 in 329,513. The value of the 2 is one-tenth the value of the 2 in 7,562. The
nexus9112 [7]

Answer: The number is 90,000.26

Step-by-step explanation:

Extracting key information from the question:-

*** The value of the "9" in Lea's riddle is 10 times the one in 329,513

*** The value of the "2" in the riddle is 1/10 the value of the 2 in 7,562.

*** The value of the 6 in the riddle is one-tenth the value of the 6 in 4.68

*** We are required to solve this possible and reveal the number.

Now, in the number 329,513 the place value of 9 is 9,000. According to the information provided, the value of the 9 in the riddle is ten times the value of the 9 in 329,513.

So, multiplying 9000 by 10 gives:-

9,000 × 10

= 90,000

Again, the value of the 2 in the riddle is one-tenth (1/10) the value of the 2 in 7,562. The value of 2 in 7,562 is 2 units, therefore one-tenth of this 2 units will give:-

1/10 × 2

= 0.2

Similarly, the value of 6 in the puzzle is one-tenth (1/10) the value of the 6 in 4.68; The 6 here is 6 hundredth = 0.6

Therefore, the value of 6 in the puzzle is:

1/10 × 0.6

= 0.06

In order to discover the number in Lea's riddle, we will then add up the calculated values:-

= 90,000 + 0.2 + 0.006

= 90,000.26

This number is the answer to Lea's riddle.
