Answer:
4.5-8-11.5-15
Step-by-step explanation:
The sequence is adding 3.5 each time
Answer:
D
Step-by-step explanation:
Area of triangle= ½ ×base ×height
Since the length of the base and the height of the triangle is equivalent to the length of a side of the square, s,
area of triangle
= ½ ×s ×s
= ½s²
Given that the area of the triangle is 12.5 units²,
½s²= 12.5
Multiply both sides by 2:
s²= 12.5(2)
s²= 25
Square root both sides:
s= 5 units
(reject negative value since s > 0)
Answer:
180.1%
Step-by-step explanation:
As a rule, when converting from a number to a percentage, you multiply by 100. Therefore, 1.801 = 180.1%
First, the rectangle:
We have the measurements of a length of 4, and width of 2. The area of a rectangle is Length times Width, therefore:
4x2=8 ft squared for the rectangle.
Now the Triangle:
We see that the whole left side is 4ft, and that the rectangle's width is 2ft; therefore, the left side of the triangle is 2 ft (4-2).
The area of a triangle is 1/2Base times Height. The base is 4, and the height is 2; therefore:
1/2x4x2=4 ft squared.
Now we add our areas for the total:
4+8=12 ft squared
I hope this Helps!
I think it might be line D.
