Answer:
1. VW = 22
2. x = 87
Step-by-step explanation:
Question 1:
SU = 11 (given)
SU = ½(VW) => midsegment theorem
11 = ½(VW) => Substitution
Multiply both sides by 2
2*11 = VW
VW = 22
Question 2:
UV = x + 13
RT = x - 37
RT = ½(UV) => Midsegment Theorem
x - 37 = ½(x + 13) => Substitution
Multiply both sides by 2
2(x - 37) = x + 13
2x - 74 = x + 13
2x - 74 + 74 = x + 13 + 74
2x = x + 87
2x - x = x + 87 - x
x = 87

The length of the altitude of the equilateral triangle is a√3/4 units.
What is a triangle?A triangle is a two - dimensional figure with three sides and three angles.The sum of the angles of the triangle is equal to 180 degrees.∠A + ∠B + ∠C = 180°Given is to find the length of the altitude of the equilateral triangle.
An equilateral triangle is a triangle whose all sides are equal. All the angles of a given equilateral triangle are 60 degrees.
The length of the altitude of the equilateral triangle can be found out using the Pythagoras theorem.
Draw a median from one vertex on the opposite side to that vertex and apply Pythagoras theorem to one of the right triangle.
We can find the length of the altitude to be -
L = a√3/4
Therefore, the length of the altitude of the equilateral triangle is a√3/4 units.

Janae solved the equation 3.67 = c − 2.13 , and found the value for c. Janae's solution was c =1.54 Do you agree or disagree with her solution. Explain. Show your work.
Answer:
Solution;
given equation : 3.67 = c - 2.13
On solving equation, we get
c = 3.67 +2.13
c = 5.8

Fill in the missing areas for Claire's garden table:

A 50
If you have the answers for this one please list all of them below with the answer for the table (if you took the test)
Answer:
[tex]\begin{array}{cccccc}x & {1} & {2} & {3} & {4} & {5} \ \\ y & {14} & {13} & {12} & {11} & {10} \ \\ A & {14} & {26} & {36} & {44} & {50}\ \end{array}[/tex]
Step-by-step explanation:
Given
[tex]\begin{array}{cccccc}x & {1} & {2} & {3} & {4} & {5} \ \\ y & {14} & {13} & {12} & {11} & {10} \ \\ A & { } & { } & { } & { } & {50}\ \end{array}[/tex]
Required
Complete the table of Areas
Using the complete column:
Where x = 5, y = 10 and A = 50,
We can deduce that, the area is calculated as:
[tex]A = 5 * 10 = 50[/tex]
i.e.
[tex]A = x * y[/tex]
So, for other values of x and y, the area is calculated as thus:
[tex]x = 1; y = 14[/tex]
[tex]A = 1 * 14 = 14[/tex]
[tex]x = 2; y = 13[/tex]
[tex]A = 2 * 13 = 26[/tex]
[tex]x = 3; y=12[/tex]
[tex]A = 3 * 12 = 36[/tex]
[tex]x =4;y =11[/tex]
[tex]A = 4 * 11 = 44[/tex]
So, the complete table is:
[tex]\begin{array}{cccccc}x & {1} & {2} & {3} & {4} & {5} \ \\ y & {14} & {13} & {12} & {11} & {10} \ \\ A & {14} & {26} & {36} & {44} & {50}\ \end{array}[/tex]
The ideal output of a particular oil-rig in the Mexican Gulf is at least 2000 barrels per day. If the output is lesser than that, the foreman raises an red flag at the end of the day. Old Joe the Retired Statistician watches from the shore every day. After 28 days, the red flag was raised on 16 of those days. Could Joe conclude that the oil-rig is operating at a non-ideal condition most of the time
Answer:
Mexican Gulf Output of a Oil-Rig
Based on 57% red flag days, Joe, the retired statistician, who watches from the shore for the red flag every day, cannot conclude that the oil-rig is operating at a non-ideal condition most of the time, but more of the time.
Step-by-step explanation:
Ideal output of a particular oil-rig, at least = 2,000 barrels per day
When output is lesser than 2,000, a red flag is raised by the foreman
Number of days counted = 28
Number of days when red flag was raised = 16
Proportion of days when the red flag was raised = 16/28
= 0.57
or 57%

0.36(18)+0.04x=0.12(24+x)
Answer:
x = 45
Step-by-step explanation:
0.36(18) + 0.04x = 0.12(24 + x)
6.48 + 0.04x = 2.88 + 0.12x
0.04x - 0.12x = 2.88 - 6.48
-0.08x = -3.6
0.08x = 3.6
x = 3.6/0.08
x = 45

A football is kicked into the air. The height of the football can be modeled by the equation
h = -16x^2 + 16x, where h is the height reached by the ball after x seconds. When does the
ball touch the ground?
Answer:
x = 0 and x = 1
Step-by-step explanation:
Given that,
A football is kicked into the air. The height of the football can be modeled by the equation :
[tex]h = -16x^2 + 16x[/tex]
Where
h is the height reached by the ball after x seconds
When it touches the ground, h = 0
So,
[tex]-16x^2 + 16x=0\\\\16x(-x+1)=0\\\\x=0\ and\ x=1[/tex]
So, it will touch the ground at x = 0 and x = 1 seconds.
Find the work W done by a force of 3 pounds acting in the direction 60° to the horizontal in moving an object 4ft (0,0) to (4,0)
Answer:
[tex]\frac{3}{2}i + \frac{3\sqrt{3} }{2}[/tex]j
Step-by-step explanation:
The work done by the force in moving the object is 10 ft-lb.
What is force?Force is an influence or interaction that can change the motion or shape of an object with mass.
It can be described as a push or a pull that has both magnitude and direction.
Force is equal to the product of the mass of the object and its acceleration.
Given,
F = 3 p
d = 4 ft
The work formula:
W = F x d
W = 4 p x cos 60° x 5 ft
= 10 ft lb.
Hence, the work done by the force in moving the object is 10 ft-lb.
