14) At a school 5/8 of the teachers are male
There are 72 teachers
work out how many teachers are female
Answer:
45
Step-by-step explanation:
72 ÷ 8 = 9. Every 9 teachers is [tex]\frac{1}{8}[/tex]. Since there are [tex]\frac{5}{8}[/tex]teachers that are male, 9 x 5 = 45 female teachers, which leaves 25 male as well

Suppose the graph of a cubic polynomial function
has the same zeroes and passes through the
coordinate (0, -5).
Describe the steps for writing the equation of this
cubic polynomial function.
DONE
Answer:
Use the zeroes to determine the roots.
Write the polynomial as a product of the leading coefficient, a, and the factors, where each factor is x minus a root.
Use the y-intercept (0, –5) to solve for the leading coefficient.
Substitute the leading coefficient into the polynomial function for a and simplify.

The sum of two consecutive integers is 41. What are the two integers?
Answer:
Step-by-step explanation:
Let the smaller of two consecutive integer be x therefore other integer is x+ 1
As per statement the sum of two consecutive integers is 41. To find out the integers.
x + (x + 1) = 41
x + x + 1 = 41
2x + 1 = 41
2x = 41 - 1
2x = 40
x = 40/2
x = 20
The smaller of two consecutive integers is 20, thus other integer is x + 1 = 20 + 1 = 21
The two consecutive integers are 20 and 21
Answer the two consecutive integers are 20 and 21

A 180 pound person is hanging onto a 15-foot rope. Assuming the rope is uniform and that it weighs 2 pound per foot, set up (but do not evaluate) the integral that would calculate the work required to pull the person up 15 feet. Explain what of the values in your expression represent by labeling each.
Answer:
The answer is "g= 32 FPS"
Step-by-step explanation:
Given value:
[tex]mass = 180\\\\length= 15 \\\\\lambda = \frac{ mass}{ length} = 2 \ \text{pound per foot} \\\\\bold{Formula}\\\\ \to w \int_{a}^{b} F \cdot d \ dx = \int_{0}^{15} (2x+180) \ g \ dx[/tex]
by solving the value we get the value of g that is equal to 32.

Describe two differences in the atomic structure of nitinol and the atomic structure of either nickel or titanium that result in different physical properties of the elements used to make nitinol. CAN ANYONE HELP, PLEASE!!!!
Nitinol is an alloy of nickel and titanium, it has two structures, austenite or martensite, and nickel and titanium are elements, that contain 28 and 22 electrons respectively.
What is nitinol?Nitinol is an alloy containing an equal quantity of elements of nickel and titanium.
It is a superelastic alloy and has shape memory capacity.
It retains its shape after reforming into another shape by an increase in temperature.
Thus, the difference is that Nitinol is an alloy of nickel and titanium, it has two structures, austenite or martensite, and nickel and titanium are elements, that contain 28 and 22 electrons respectively.

The mass of a cube, M (kg), is proportional to the cube of the length of its edge, L(m). The mass of the cube is 80 kg when the length of its edge is 35 cm. Work out M (to 2 DP) when L=0.3 m
Answer:
M=K*L
(K is the constant we use)
when L=35cm, M=80,
meaning K=80/0.35=228.571428571
so when L=0.3
we do 0.3*228.571428571=68.5714285713
rounded to 2dp= 68.57kg
9514 1404 393
Answer:
50.38 kg
Step-by-step explanation:
The mass is proportional to the cube of edge length, So, if the edge length is decreased by a factor of 30/35 = 6/7, the mass is decreased by a factor of (6/7)³. That is, the smaller cube will have a mass of ...
(80 kg)(6/7)³ ≈ 50.38 kg
__
If you want to write an equation, you can write the equation for the proportionality:
M = kL³
80 kg = k(0.35 m)³
k = 80/0.35³ kg/m³
Then for the shorter length, we have ...
M = k(0.3 m)³ = 80(0.3/0.35)³ kg = 80(6/7)³ kg ≈ 50.38 kg . . . . as above
Solve for x: 5x + 15 = 28

Answer:
x=2.6
Step-by-step explanation:
1)write equation
2)put line through equal sign(if on paper, its way easier to put a line through.)
3)subtract 15 from 15
4)subtract 15 from 28(13)
If it were to be a negative 15 youd add 15. Never add or subtract to a number with a letter!
5)what's left over is 5×=28 divide 5 on both sides.

Determine whether each sequence is an arithmetic sequence. Write yes or no. Explain. 7, 10, 13, 16, ...
Answer:
The given sequence is an arithmetic sequence.
Step-by-step explanation:
Given sequence is:
7, 10, 13, 16, ...
Here
[tex]a_1 = 7\\a_2 = 10\\a_3 = 13\\a_4 = 16[/tex]
In order for a sequence to be an arithmetic sequence the common difference between the consecutive terms of the sequence should be same. Common difference is denoted by d.
So,
[tex]d = a_2 - a_1 = 10-7 = 3\\d = a_3 - a_2 = 13-10 = 3\\d = a_4-a_3 = 16-13 = 3[/tex]
As we can see that the common difference is same for consecutive terms.
The given sequence is an arithmetic sequence.

A snowplow has maximum speed of 45 miles per hour on a dry highway. Its maximum speed decreases by 1.6 miles per hour for every inch of snow on the highway. According to this model, at what snow depth will the snow plow be unable to move?
Answer:
28.125
Step-by-step explanation:
If it is going 45mph and every hour it decreases 1.6mph per inch of snow added. so 45 divided by 1.6 is 28.125.
The length of human pregnancies from conception to birth varies according to a distribution that is approximately Normal with mean 266 days and standard deviation 16 days.
Required:
a. How short are the shortest 2.5% of all pregnancies?
b. Between what values do the lengths of the middle 95% of all pregnancies fall?
c. How long do the longest 2.5% of pregnancies last?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Mean (m) = 266 days
Standard deviation (s) = 16 days
A.) p(( Z ≤ (x - m) /s) = 2.5%
p(( Z ≤ (x - 266) /16) = 0.025
(x - 266) /16 = - 1.96 (Z probability calculator)
x - 266 = - 31.36
x = - 31.36 + 266
x = 234.64
B.)
p(( Z ≤ (x - m) /s) = 2.5%
p(( Z ≤ (x - 266) /16) = 0.025
(x - 266) /16 = - 1.96 (Z probability calculator)
x - 266 = - 31.36
x = - 31.36 + 266
x = 234.64
p(( Z ≤ (x - m) /s) = 2.5%
p(( Z ≤ (x - 266) /16) = 0.025
(x - 266) /16 = 1.96 (Z probability calculator)
x - 266 = 31.36
x = 31.36 + 266
x = 297.36
Hence,
234.64 < x <297.36
C.)
p(( Z ≤ (x - m) /s) = 2.5%
p(( Z ≤ (x - 266) /16) = 0.025
(x - 266) /16 = 1.96 (Z probability calculator)
x - 266 = 31.36
x = 31.36 + 266
x = 297.36
