A ladder is leaning against a building so that the distance from the ground to the top of the latter is 1 foot less than the len

masha68 [24]

Answer:

$25\text{ feet}$

Step-by-step explanation:

The ladder, ground, and building form a right triangle where the vertical distance between the top of the ladder and the bottom of the ground is one leg, the horizontal distance between the bottom of the ladder and the building is another leg, and the length of the ladder is the hypotenuse.

For any right triangle, the Pythagorean Theorem states that the sum of the squares of both legs is equal to the hypotenuse squared ( $a^2+b^2=c^2$ ), where $c$ is the hypotenuse.

Let the length of the ladder be $\ell$ (hypotenuse of right triangle). The distance between the top of the ladder and the ground (vertical distance) can be represented as $\ell -1$ .

From the Pythagorean Theorem, we then have:

$7^2+(\ell-1)^2=\ell^2$

Expand using $(a-b)^2=a^2-2ab+b^2$ :

$49+\ell^2-2\ell+1=\ell^2$

Subtract $\ell$ from both sides and add $2\ell$ to both sides:

$49+1=2\ell$

Combine like terms:

$50=2\ell, \\2\ell =50$

Divide both sides by 2:

$\ell=\frac{50}{2}=\boxed{25\text{ feet}}$

Therefore, the length of the ladder is 25 feet.

Jared is going to plant 20 small plants around the edge of a circular garden that is 8 feet in diameter. If he spaces the plants

Hatshy [7]

Answer:

The space between the plants is approximately 1.26ft

Step-by-step explanation:

Given

Circular Garden

Number of plants = 20

Diameter of garden = 8ft

First, the circumference of the garden needs to be calculated; This is so because the plants that will be placed at the edge of the garden will occupy the circumference of the circle.

Calculating the circumference....

Circumference = 2πr

Where r = radius

r = ½ * diameter.

r = ½ * 8ft

r = 4ft

So,

Circumference = 2π * 4

Circumference = 8π ft

Given that the plants will be spaced evenly.

The distance between them = Circumference ÷ Number of plants

Distance = 8π/20

Distance = 0.4π ft.

Solving further to get actual distance (take π as 22/7)

Distance = 0.4 * 22/7

Distance = 8.8/7

Distance = 1.2571428571 ft

Distance = 1.26ft (Approximated)

Hence, the space between the plants is approximately 1.26ft

Pls help! Which multiplication problem is represented by the model?

Alinara [238K]

Answer:

1/2 x 4/5

Step-by-step explanation:

Step 1. Multiply the numerators:

1/12 × 4/5 = 4 x 1 = 4

Step 2. Multiply the denominators:

5 x 12 = 60

Step 3. Simplify the fraction:

4/60 = 1/15
