Answer:
Step-by-step explanation:
If the ratio of the sides is 13:14:15, we can say that the length of each side is 13x, 14x and 15x.
Then, if the perimeter is 84 m, we have:
The length of each side is:
Now, to find the area of the field, we can use the following formula:
Where a, b and c are the sides and p is the semi perimeter:
So we have that:
Answer:
The answer is:
58 km/hr
16.1 m/s
Step-by-step explanation:
406 km in 7h
x km in 1h
x= 1 x 406/7
x= 58 km/hr
58 km/hr ⇒⇒⇒⇒⇒⇒ 16.1 m/s
The answer is 4. Let's analyze that question. Firstly, it costs 75 dollars for a booth at the market. This fee is a one time fee. The materials for each chair is 45 dollars, meaning that the price that he's selling it for leaves 20 dollars ( 65 dollars, selling price - 45 dollars, materials price). So, he makes 20 dollars from each chair. However, we still have to pay off the fee. So, we must find how many times we need to multiply 20 dollars until it matches or cancels out the fee (75 dollars). That would be 20 * 4 = 80.
