Answer:
CDE=50 degrees ACD=100,BAC=30 degrees.
Answer:
20 is 10% of 200
Step-by-step explanation:
We have, 10% × x = 20
or,
10
100
× x = 20
Multiplying both sides by 100 and dividing both sides by 10,
we have x = 20 ×
100
10
x = 200
If you are using a calculator, simply enter 20×100÷10, which will give you the answer.
Answer:
Step-by-step explanation:
Let's put in some numbers to make this easier to understand.
Let's say she has to travel 20 km.
On Monday, she travels at 4 kph. This takes 5 hours.
On Tuesday she travels 25% faster, at 5 kph. This takes 4 hours.
To figure percent reduction we take
100 % * (old - new) / old
100 % * (5 hr - 4 hr ) / 5 hr
100 % * 1 hr / 5 hr
100 % * 0.20
20% reduction.
The garden with the largest area is garden b with an area of 6000 feet squares
<h3>What is the area of a rectangle?</h3>
The area of a rectangle is simply known as the number of unit squares that can fit into the rectangle.
The formula for calculating the area of a rectangle is written thus;
Area of a Rectangle = (Length × Breadth)
<h3>How to determine the area</h3>
Using the formula:
Area of a Rectangle = (Length × Breadth)
For garden a;
Length = 25 feet
Breadth = 120 feet
Substitute the values into the formula
Area of garden a = 25 × 120 = 3000 feet squares
For garden b;
Length = 50 feet
Breadth = 120 feet
Substitute the values into the formula
Area of garden b = 50 × 120 = 6000 feet squares
Therefore, the garden with the largest area is garden b with an area of 6000 feet squares.
