width = 5.5 feet and
length = 8 feet
Step-by-step explanation:
Given:
Let Width = w
then length = 2.5 + w
Area = 44.8 square feet
Required:
Find length and Width
Formula:
Putting values to find length and width
So, value of w = 5.5 and -8.1
Since width can't be negative so,
Width = w = 5.5
Length = 2.5+w = 2.5+5.5 = 8
So, width = 5.5 feet and
length = 8 feet

Answer: the top of the ladder is 20ft below the ground.
Step-by-step explanation:
The ladder makes an angle, θ with the ground thus forming a right angle triangle with the wall of the house.
The length of the ladder represents the hypotenuse of the right angle triangle.
The ground distance between the base of the house and the base of the ladder represents the adjacent side of the right angle triangle.
Therefore, to determine the height at which the ladder rest on the building, x, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
25² = x² + 15²
625 = x² + 225
x² = 625 - 225 = 400
x = √400 = 20 ft
Answer:
7a²/16
Step-by-step explanation:
Area of the triangle PTS
½ × a × a
a²/2
Length of PS:
sqrt(a² + a²)
asqrt(2)
Length of MS:
¼asqrt(2)
Triangles MCS and TPS are similar
With sides in the ratio:
¼asqrt(2) : a
sqrt(2)/4 : 1
Area of triangle SMC:
A/(a²/2) = [(sqrt(2)/4)]²
2A/a² = 1/8
A = a²/16
Area of PTMC
= a²/2 - a²/16
= 7a²/16
So this pie is 3/3rds and they ate 2/3rds of the pie so your problem will be
3/3 - 2/3 so your answer is
1/3
