Answer:

51 trees

Step-by-step explanation:

Start at one end of the 50-foot line segment.

At position 0 ft, put one tree.

Then 1 ft from 0 ft, put tree number 2.

One more foot over, at position 2 ft from the start, put tree number 3.

Notice that each tree number is one more than the number of feet.

That means at 50 ft from the stat, you put tree number 51.

The ratio of the length of a rectangle to its width is 8 to 5. If the longer side of the rectangle is 20ft, what is the length o

choli [55]

Answer: The answer is 12.5 ft.

Step-by-step explanation: Given that there is a rectangle with ratio of its length to breadth 8 : 5. Also, the longer side of the rectangle is 20 feet. We are to find the length of the shorter side.

Let, '8x' and '5x' be the length and breadth of the rectangle respectively. Since length is the longer side, so we have

$8x=20\\\\\Rightarrow x=\dfrac{20}{8}\\\\\\\Rightarrow x=2.5.$

Therefore, width, length of the shorter side will be

$W=5x=5\times 2.5=12.5~\textup{ft.}$

Thus, the length of the shorter side is 12.5 ft.

Solve each one variable equation.

uranmaximum [27]

Answer:

See below in bold.

Step-by-step explanation:

a. |x| = 6

x = 6, -6.

b. |x − 5| = 4

x - 5 = 4

x = 9.

x - 5 = -4

x = 1.

c. 2|x + 3| = −10

No solution because |x + 3| is an absolute value so is always positive.

Alvin is 9 years older than Elga. The sum of their ages is 89. What is Elga's age?

Mekhanik [1.2K]

Answer:

Alvin: 49

Elga: 40

Step-by-step explanation:

The equation is 89 = x + (x-9).
Remove the parenthesis and combine the like terms. 89 = 2x - 9
Add 9 on both sides. 98 = 2x
Divide by 2 on both sides. x = 49
49 is the age of Alvin. (49-9) 40 is the age of Elga.
