Answer:
Step-by-step explanation:
-3y = -2x + 4
3y = 2x - 4
y = 2/3x - 4/3
perp; -3/2
y + 3 = -3/2(x - 4)
y + 3 = -3/2x + 6
y = -3/2x + 3

Each employee in a company is either right-handed or left-handed.
32 of the 54 employees are female.
18 of the 41 right-handed employees are male.
Complete the frequency tree for this information.
Answer:
23 females are right handed and 9 are left handed
Step-by-step explanation:
So to get this answer :
18 OF THE 41 RIGHT HANDED EMPLOYEES ARE MALE.
The statement means that there are 41 right handed employees and 18 of those are male thus the remaining are FEMALE.
To find the number of right handed employees who are female just subtracted 18 from 41 ( becaus etotal number of right handed males is 18 and the total number of right handed employees is 41.)
SO 23 FEMALES IN THE COMPANY ARE RIGHT HANDED.
Because 23 females are right handed that means to get the number of left handed females you subtract the total number of right handed females from the total number of females in the company THUS:
32 - 23 = 9 LEFT HANDED FEMALES

Answer:
B, 7/24
Step-by-step explanation:
(x=theta)
sec(x) = 1/cos(x) so 1/cos(x) = 25/24
[tex](\frac{1}{cosx})^-1 = (\frac{25}{24} )^-1\\\\cos(x) = 24/25[/tex]
Then use the cos^-1 function on your calculator to find out theta.
Then tan your found value of theta.
You should find that tan (theta) = 7/24

Cuánto ganaría un accionista que tiene 100 acciones, si cada acción que él compró aumenta de $20.00 a $30.00
Answer:
$2,000 and $3,000
Step-by-step explanation:
The computation is shown below:
Given that
The Number of shares is 100
The Increase from $20 to $30
If the per share is $20, so the earning of the shareholder is
= 100 shares × $20
= $2,000
And ,if the per share is $30, so the earnings of the shareholder is
= 100 shares × $30
= $3,000

Step-by-step explanation:
Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
Find the area, to the nearest hundredth, of the figure
Answer:
Step-by-step explanation:
hypotenuse = √(14.4² + 6²) = √243.36 = 15.6 mi
area of triangle = 0.5×6×14.4 = 43.2 mi²
radius of semicircle = 15.6/2 = 7.8
area of semicircle = πr² = 60.84π mi²
total area = 43.2 + 60.84π ≅ 234.33 mi²
What is the sum of 5.3 x 10 to the fifth power and 3.8 x 10 to the fourth power in scientific notation
Answer:5.6 x 10^5
Step-by-step explanation:
When ever we hear sum, what comes to our mind must be addition
Here we are Adding 5.3 x 10 to the fifth power= 5.3 x 10^5 to
3.8 x 10 to the fourth power = 3.8 x 10^4
First,
Expanding the scientific notation we have that
5.3 x 10^5 = 530,000
3.8 x 10^4= 38,000
Add = 568,000
Putting back in Scientific notation we have 568000 = 5.6 x 10^5
Answer:
5.68 x 10 to the 5th power

For how many minutes did Katie run? Explain how you determined your answer.
Answer:
part A 210 Part B 4.4
Step-by-step explanation:
PART A 42 TIMES 5 210
that will be the rate she ran.
PART B 1.1 times 4 that will be the minute.
The denominator of a basketball is approximately 9 inches. what is the volume?
Answer: v=43πr3 where r is the radius. You have the diameter, that is the double of the radius, so r=92=4.5 inches. v=43π4.53=381.69 cubic inches.
Answer:
381.7
Step-by-step explanation:
to get the volume of a sphere the formula is:
V=4 /3πr3
(remember basketball isn't a circle because it is 3-d)
you plug in the radius to that formula and boom you got your answer!
(remember radius is half the diameter, and half of 9 is 4.5)
so your answer would be:
381.7

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.

Find p(-3) if p(x)= 4x^3 - 5x^2 + 7x - 10.
Answer:
p(-3) = -184
Step-by-step explanation:
p(-3) = 4(-3)^3 - 5(-3)^2 + 7(-3) -10
= 4(-27) - 5(9) - 21 - 10
= -108 - 45 - 21 - 10
= -184

The Miller Family shares a cell phone plan. Last month, Jodie used 3/4 of the minutes. Her son Billy used 4/5 of the remaining minutes. What fraction of the minutes did Billy use?
Answer: The fraction of the minutes did Billy use = [tex]\dfrac15[/tex].
Step-by-step explanation:
Let x = Total minutes given in the plan.
Last month, Jodie used [tex]\dfrac34[/tex] of the minutes.
Remaining minutes = [tex]x-\dfrac34x=\dfrac14x[/tex]
Billy used = [tex]\dfrac45(\dfrac14x)=\dfrac{x}{5}[/tex] minutes
Fraction of the minutes used by Billy = [tex]\dfrac{\dfrac{x}{5}}{x}=\dfrac15[/tex]
Hence, the fraction of the minutes did Billy use = [tex]\dfrac15[/tex].
