Answer:
Step-by-step explanation:
The given figure is a trapezoid. The perimeter of a plane figure is expressed as the the distance around the figure. Therefore
Perimeter = a2 + b2 + a1 + b1
Perimeter = 4.7 + 5.8 + 8.5 + 6.89 = 25.89 feet
The formula for determining the area of a trapezoid is expressed as
Area = 1/2(a + b)h
Where
a and b are the length of The bases are the 2 sides of the trapezoid which are parallel with one another.
h represents the height of the trapezoid.
From the diagram,
a = 4.7 feet
b = 8.5 feet
h = 5.8 feet
Area = 1/2(4.7 + 8.5)5.8
Area = 1/2 × 13.2 × 5.8
Area = 38.28 feet²
The answer is 15. 37 plus 18 equals to 55 and 22 plus 18 equals to 40. 55 minus 40 equals to 15.
Answer:
We know that our triangle has one side along the line:
y = (1/4)*x
And other side along the line:
y = -(1/4)*x.
Now, we want to find the vertex.
And we know that the vertex is the point where the two sides conect, so the vertex must be a common point of both lines.
Then we have:
y = (1/4)*x = -(1/4)*x
x = -x
The only solution to that equation is x = 0.
now we evaluate our lines in x = 0 and get:
y = (1/4)*0 = 0
y = -(1/4)*0 = 0
Then the lines intersect in the point (0, 0)
Then the vertex must be in the point (0, 0)
Well the 1/8 is for the whole sandwich because it is double the cheese that Ms. Sarah said. So Ms. Sarah is correct because it is for half of the sandwich.
Answer:
v = 85/t
Step-by-step explanation:
Velocity is the change in displacement of a body with respect to time. It is expressed as
velocity = displacement/time
v = d/t
Given
d = 85km
t = t
Substitute tis parameters into the function;
v = 85/t
Hence the velocity v as a function of travel time t in hours is expressed as;
v = 85/t
