If TU = 4x, UV = 2x + 14, and TV = 7x – 5, what is UV?
T
4x
U
2x + 14
7x - 5
Simplify your answer and write it as a proper fraction, mixed number, or integer
Submit
Answer: UV = 52
Concept:
Additive property of length, or the segment addition postulate, states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.
Solve:
Given information
TU = 4x
UV = 2x + 14
TV = 7x - 5
Given expression deducted from the additive property of length
TV = TU + UV
Substitute values into the expression
7x - 5 = 4x + 2x + 14
Combine like terms
7x - 5 = 6x + 14
Subtract 6x on both sides
7x - 5 - 6x = 6x + 14 - 6x
x - 5 = 14
Add 5 on both sides
x - 5 + 5 = 14 + 5
x = 19
Find UV by substituting the value of x
UV = 2x + 14 = 2 (19) + 14 = [tex]\boxed{52}[/tex]

let 45 be y
let unknown be X
to get x
X=( lcm * gcf) / y

What is 3x+8x=13+31?
Answer:
x = 4
Step-by-step explanation:
3x+8x=13+31
Combine like terms
11x =44
Divide by 11
11x/11 = 44/11
x = 4
The answer you are looking for is x=4.
Solution:
3x+8x=13+31
Combining and adding similar terms,
11x=44
Dividing both sides by 11,
So, therefore,
The final answer is x=4.

In a survey, survey of 1200 students who have passed SEE 150 like to admit in science Faculty 600 in humanity first and 240 like to admit either of faculties and the rest were found not to be admitted in both faculties
Hence, not to be admit in any faculty = N
Science + Humanity - Either + None = 200
=> 150 + 600 - 240 + N = 1200
=> 750 - 240 + N = 1200
=> N = 700

Answer:
k = -10
Step-by-step explanation:
In order to solve for k, we need to isolate the variable. This means we need k to be on one side of the equation by itself.
We are given:
[tex]-\frac{6}{5}k=12[/tex]
The first thing I would do is multiply both sides of the equation by 5:
[tex](5)-\frac{6}{5}k=12(5)[/tex]
This leaves us with:
[tex]-6k=60[/tex]
Now, in order to get k by itself, we need to divide by -6 on both sides:
[tex]\frac{-6k}{-6}=\frac{60}{-6}[/tex]
Therefore:
[tex]k=-10[/tex]

After the release of radioactive material into the atmosphere from a nuclear power plant at Chernobyl (Ukraine) in 1986, the hay in Austria was contaminated by iodine 131 (half-life 8 days). If it is safe to feed the hay to cows when 10% of the iodine 131 remains, how long did the farmers need to wait to use this hay?
Given the data provided, it follows that the farmers must wait for 26 days before feeding the hay to cows.
What is half life?The term half life is defined as the time taken for half of the original amount of the radioactive sample to remain.
Now we know that;
half life = 8 days
Original amount = No
Amount left after t days = 0.1No
time taken = t days
Hence;
0.693/8 = 2.303/t log (No/0.1No)
0.087 = 2.303/t
t = 2.303/0.087
t = 26 days

6. (4 points) (a) The edge of a cube was measured to be 6 cm, with a maximum possible error of 0.5 cm. Use a differential to estimate the maximum possible error in computing the volume of the cube. (b) Using a calculator, find the actual error in measuring volume if the radius was really 6.5 cm instead of 6 cm, and find the actual error if the radius was actually 5.5 cm instead of 6 cm. Compare these errors to the answer you got using differentials.
Answer:
A) ± 54 cm^3 ( maximum possible error in volume )
B) i) 58.625 cm^3 ii) 49.625 cm^3
Step-by-step explanation:
A) using differential
edge of cube = 6 cm , maximum possible error = 0.5 cm
∴ side of cube ( x )= ± 0.5 cm
V = volume of cube
dv /dx = d(x)^3 / dx
∴ dv = 3x^2 dx ---- ( 1 )
input values into 1
dv = 3(6)^2 * ( ± 0.5 )
= ± 54 cm^3 ( maximum possible error in volume )
B) Using calculator
actual error in measuring volume when
i) radius = 6.5 cm instead of 6 cm
V1= ( 6.5)^3 = 274.625 , V = ( 6)^3 = 216
actual error = 274.625 - 216 = 58.625 cm^3
ii) radius = 5.5cm instead of 6cm
actual error = 49.625 cm^3
