Answer:

The distance is 5.20m

Step-by-step explanation:

Here, we want to get the height of the ladder

To get this, we need to understand that we have a right triangle, with the base of the triangle as 3 m, the angle at the downward part is 60, and we want to get the height of the triangle

The angle here faces the height we want to calculate

This height is known as the opposite

What we have is the adjacent

Now, the trigonometric identity that relates the opposite and the adjacent is the tan

The tangent of an angle is the ratio of the opposite to the adjacent

Mathematically;

tan 60 = h/3

h = 3 tan 60

h = 5.20 m

The ladder is at a height of 5.20 m above the ground

Using the PEDMAS rule, the solution to the problem is calculated as: 16/3 = 5.3.

<h3>How to Apply the PEDMAS Rule?</h3>

Given a mathematical expression that involves solving it using several operations, the PEDMAS rule guides us in the order of operation such problem can be solved.

Given the expression, 7/6 ÷ 0.25 × 7/8, the first operation to perform based on the the PEDMAS rule is multiplication/division.

7/6 ÷ (0.25 × 7)/8

7/6 × 8/(0.25 × 7)

= 1/6 × 8/(0.25 × 1)

= 1/6 × 8/0.25

= 1/6 × 32

= 32/6

= 16/3 = 5.3

Jacob used 1/7 of a liter of water to fill 1/9 of the fish aquarium. How many liters of water are needed to fill the aquarium?
laila [671]
Jacob used 1/7 of a liter of water.
He needs to fill 1/9 of the fish aquarium.
Find how many liters would Jacob need to fill the aquarium
=> Let x = liters of water need to fill the aquarium
=> x/1 = 1/7 divided by 1/9
=> x = 1/7 x 9/1
=> x = 9/7, since this is an improper fraction, let’s convert it to mixed fraction
=> x  = 1 and 2/7
So, Jacob need 1 and 2/7 liter of water to fill the whole aquarium.
