Step-by-step explanation:
A man weighing 800 N is hanging from a 2 mm diameter titanium wire with a cross-section of 3 x 10^-6 m^2. Will the wire break?
Answer:
Since stress is greater than ultimate strength, the wire will break.
Step-by-step explanation:
The titanium wire is experimenting an axial load. Ultimate strength equals [tex]2.20\times 10^{8}\,Pa[/tex]. The wire shall break if and only if stress is at least equal to ultimate strength. The equation for axial stress ([tex]\sigma[/tex]), measured in pascals, in the wire with circular cross-section is:
[tex]\sigma = \frac{4\cdot F}{\pi\cdot D^{2}}[/tex] (1)
Where:
[tex]F[/tex] - Axial force, measured in newtons.
[tex]D[/tex] - Cross-section diameter, measured in meters.
Please notice that axial force is the weight of the man hanging from wire.
If we know that [tex]F = 800\,N[/tex] and [tex]D = 0.002\,m[/tex], then the axial stress experimented by the titanium wire is:
[tex]\sigma = \frac{4\cdot (800\,N)}{\pi\cdot (0.002\,m)^{2}}[/tex]
[tex]\sigma \approx 2.546\times 10^{8}\,Pa[/tex]
Since stress is greater than ultimate strength, the wire will break.

What is equivalent to 7x(4x-5)
7x(4x-5)
Distribute
28x^2-35x
Ans : 28x^2-35x
Answer:
28x - 5
Step-by-step explanation:
coeffecients with the same variable can be multiplied added subtracted divided so i multiplied 7 and 4 because they have the same variable which is X so it would be 28x and you can't multiply 7x by 5 because it doesnt have a variable consider multiplying if it has the same variable when it has a variable. so it would just be 28x - 5
Please help!!! I’m stuck
Answer:
20/29
Step-by-step explanation:
Since 20inches is the opposite side size to the angle. Opposite = 20.
[tex] \cos( \alpha ) = \frac{adj}{hyp} [/tex]
Note: Hypothenus is the longest side of a right angle triangle which is 29inches.
Thus,
[tex] \cos( \alpha ) = \frac{20}{29} [/tex]
Find the difference:

There are 45 students who participate in track. Of these, 18 do an event other than running. What percent of the students do an event other than running?
Answer:
27
Step-by-step explanation:
To find out how many people do something OTHER than running, you have to take the total amount of students participating and subtract the number of runners. 45 - 18 = 27.
Answer:
40%
Step-by-step explanation:
18÷45 = 0.4 × 100 = 40%

What conclusion can you make from the information below?
Three boys (Dmitri, Ken, and Adam) have three different favorite colors (red,green, and blue)
• Dmitri does not like red
• Adam does not like red.
A. Dmitri's favorite color is blue.
B. No one likes green
C. Ken's, favorite color is red
D. Ken's favorite color is not red.
========================================================
Explanation:
We're told that Dmitri and Adam do not like red. So that must mean that Ken likes red. This immediately leads to choice C as the answer. This is assuming that each boy picks one of the three colors (and no colors can be repeated).
----------------
Extra info:
Choice A is false because we're not sure if Dmitri likes blue or green. We don't have enough info. Choice B is false because someone has to pick green. There are three boys and three colors. Again I'm assuming each person picks one color and the colors aren't repeated.Choice D is false because it contradicts choice C.Look at the information below, decide what type of substance the paint is.

Write the equation of a line that is parallel to the line y=4x+2 and passes through the point (4,1)
Answer:
y = 4x-13
Step-by-step explanation:
The standard equation of the line is y = mx+c
m is the slope
c is the intercept
Given the equation y = 4x+2
The slope m = 4
Substitute m = 4 and the given point into the formula y = mx+c
1 = 4(4)+c
1 = 14+c
c = -13
Get the equation
Recall that y = mx+c
y = 4x + (-13)
y = 4x-13
Hence the required equation is y = 4x-13

The ratio of students to teachers at a school is 19 : 1. At this school, there are 400 people (teachers and students). How many of these 400 people are students? (enter number only, without the unit)
Answer:
There are 380 students and 20 teachers.
Answer:
380
Step-by-step explanation:
Let 19x = no. of students
x = no. of teachers
Then, x + 19x = 400
20x = 400
x = 20
19x = 19(20) = 380
