A tank is full of water. Find the work required to pump the water out of the spout. Use the fact that water weighs 62.5 lb/ft3
The work required to pump the water out of the spout is 5000ft⋅lb
Given
The volume V=12(4ft)(5ft)(6ft)=60ft3,
Then the weight is w = γV = (62.5lb /ft³) (60ft³) = 3750lb.
Since work is force × distance, you need a distance here, and the appropriate one is the distance you must raise the center of mass to get the H2O out of the spout.
Since the center of mass of a uniform triangular area is 13 of the way from any side, the distance is (4ft)/3 so the work is (3750lb) (4ft)/3=5000 ft-lb.
In calculus, the area of a horizontal section yft from the lowest point is (5ft) × (6ft) × y / (4ft) = 7.5y ft2.
We have to lift that slice 4ft−y, so work is
w = [tex]\int\limits^4_0[/tex] (62.5)(4 − y) (7.5y)
dy = (62.5)[15y2−2.5y3]40 = 5000ft⋅lb
The work required to pump the water out of the spout is 5000ft-lb

A ferry traveling along the river at a constant rate covers of the distance between two ports in of
an hour. At this rate, what fraction of the distance between the two ports can the ferry travel in one
hour?
(A) 3/24 (B) 1/3 (C) 7/18 (D) 25/42
The formula speed = distance ÷ time can be rearranged, just like any other equation. The formula can be rearranged in three ways: speed = distance ÷ time , distance = speed × time.
Speed tells us how slow or fast an object moves. Distance refers to extent of space between two events. Time refers to an interval separating two events.
ASSUME a ferry travels 1/7th of the distance between two ports in 3/5 hours , then it will be able to cover 5/6th part of the distance between two ports in 3.5 hours.
Distance that the ferry would be able to trave in 1 hour can be found out by :
unit rate=distance / time
=1/7÷3/5
Reciprocal:
=1/7×5/3
=5/21th of distance per hour
The distance that the ferry would be able to travel in 3.5 hours:
= (5/21 ) ×3.5
=(5/21)×(7/2)
Further solving:
=(5/3)×(1/2)
5/6th of the distance between two ports.

Angle B is a complement of angle A and the measurement of angle A = 65.2°. Find the measurement of angle B
Answer:
24.8°
Step-by-step explanation:
Complementary angles sum 90°
65.2° + B° = 90°
B° = 90° - 65.2°
B° = 24.8
Angle B from the information given is 24. 8°
How to determine the angleNote that complementary angles sum up to 90°
From the information given, we have that
Angle A + Angle B = 90°
If angle A = 65. 2°
Angle B = 90 - 65. 2
Angle B = 24.8°
Thus, angle B from the information given is 24. 8°

Answer:
x=0. The explanation is below.
Step-by-step explanation:
So, it is run 2 rise 6. We can fact-check that with 1 to 3 to 5 and 1 to 7 to 13. So, the slope is 3 because of rise over run. So, we can make an equation with y = mx + b. m = 3 because that is the slope. 1=3(1) + b. b=-2. So, the equation is y=3x-2. We can find any x using y and vice versa if we find the equation.
For this part, -2=3x-2. 3x=0. x=0.

Part A: Describe how you can use similar triangles to explain why the slope of the graph between points A and B is the same as the slope of the graph between points A and C.
Part B: What are the initial value and slope of the graph, and what do they represent? (6 points) Please try to explain it as simply as possible
The answers are:
Part A: The slope of AB and BC are the same.Part B :The initial value is 60 m and the slope is 40 m/min.What is the triangles about?Note that the graph depict the depth, y, in meters, of a shark that moves from the surface of an ocean for a given amount of time, x, in minutes.
So:
Part A :
We look at the two right triangles: Δ ABD and Δ BCE, and where D(2,100) and E(1,60) points.
Since the triangle are the same and thus, the slope of line segment AB: tan θ = AD/BD
= 140 - 100 / 2 - 1
= 40
Since the the slopes of line segment BC will be:
tan a = BE/CE
= 100 - 6 / 1 - 0
= 40
So, θ = α and the slope of AB and BC are similar.
Part B :
Using the graph, one can see that the initial value of the graph is 60 m and it stands for the initial position of the shark
e.g. at point t = 0 min, the shark was seen at a depth of 60 m from the water surface.
So therefore, since the slope of the graph is 40 it implies that the rate of change of distance from the Ocean surface of the shark in regards to the time in minutes have to be 40 m per min.
Therefore, The answers are:
Part A: The slope of AB and BC are the same.
Part B :The initial value is 60 m and the slope is 40 m/min.

4. Mr.X is thinking of two numbers. -The sum of the numbers is 212. -The difference between them is 88. Solve a system of equations to determine the value of each number.
Answer:
62 and 150
Step-by-step explanation:
let the 2 numbers be x and y , x > y , then
x + y = 212 → (1)
x - y = 88 → (2)
add the 2 equations term by term to eliminate y
2x + 0 = 300
2x = 300 ( divide both sides by 2 )
x = 150
substitute x = 150 into (1)
150 + y = 212 ( subtract 150 from both sides )
y = 62
the 2 numbers are 62 and 150
Alone LiZ can complete a project in 12 hours and Julia could do it alone in 24 hours. Liz worked on the project alone 2 hours before Julia joined her. How many hours did they work together to finish ?
Answer:
Julia and Liz worked 10 hours to finish the project.
Step-by-step explanation:
I don't know if I am 100% right, but I believe this is the answer.
If you take the 24 hours it will take Julia to finish the project on her own and subtract the time it would take Liz you would have 12 hours left then take the 2 hours Liz has already been working on the project you would have 10 hours for both of them to finish the project together.

Given △qrs ~ △xyz, what is the value of tan(q)? three-fifths three-fourths four-fifths four-thirds
The value of tan(Q) = 3/4, given that ΔQRS ~ ΔXYZ. Computed using properties of similar triangles. Hence, the second option is the best choice.
According to the properties of similar triangle, the corresponding sides of similar triangles are in proportion.
In the question, we are given that ΔQRS ~ ΔXYZ.
By properties of similar triangles, we know that:
QR/XY = RS/YZ = SQ/ZX.
From this, we can show that:
RS/SQ = YZ/ZX ...(i).
We are asked to find the value of tan(Q).
By trigonometric ratios, we know that:
tan(Q) = Perpendicular/Base = RS/SQ.
From (i), we know that RS/SQ = YZ/ZX.
From figure, we know that YZ = 9, and ZX = 12.
Thus, YZ/ZX = 9/12 = 3/4.
Thus, tan(Q) = RS/SQ = YZ/ZX = 3/4.
Hence, the value of tan(Q) = 3/4, given that ΔQRS ~ ΔXYZ. Computed using properties of similar triangles. Hence, the second option is the best choice.

Q = {x | x ∈ N, 1 ≤ x ≤ 15, x ∈ {1, 3, 6, 9, 10, 15}}

Q = {x | x ∈ N, 1 ≤ x ≤ 15, x ∈ {1, 3, 6, 9, 10, 15}}

angle bisectors of each angle of the triangle
the incenter of the triangle
Option B is right perpendicular bisectors of the sides of the triangle
What circumcircle?If we draw a circle through all the vertices of a triangle then the circle obtained is the circumcircle of the given triangle. We have in a triangle there are some properties inherent.
One is the perpendicular bisectors of all sides are concurrent. These three concur at a point called the circumcentre of the triangle.
When we draw a perpendicular bisector for a side AB, we get that all points on the perpendicular bisector are equidistant from A and B.
When we take the point of intersection of the perpendicular bisector of AB and BC, we have the intersecting point S(say) is equidistant from A and B and also from B and C
In short, this is equidistant from all 3 vertices and hence is the centre of the circumcircle of triangle ABC

In this circle, the area of sector COD is 50.24 square units.
The radius of the circle is ____ units, and mAB is ____ units.
Answer:
Radius = 8 units
Length of arc AB = 8.37758 units
Step-by-step explanation:
The sector COD is 1/4 the size of the circle.
the vertex angle is 90° and a circle has 360° at the center.
So the area of sector COD/area of Circle = 90/360 = 1/4
This means the area of the circle is 4 * 50.24 = 200.96 square units
Area of circle = πr² where r is the radius
πr² = 200.96
r² = 200.96/ π = 63.9676 ≅ 64
Therefore r = √64 = 8 units
The circumference of the circle is 2πr = 16π units
arc AB has a vertex angle of 30°.
30°/360° = 1/6
So the length of the arc is 1/6th the circumference of the circle =
(1/6) * 16π = 2.67π units or 8.37758 units
