Four people applied for a job as an assistant manager at a store. Only two of these people will be hired.
Answer:
50% of the applicants will be hired.
Step-by-step explanation:
Given that four people applied for a job as an assistant manager at a store, but only two of these people will be hired, the following calculation must be performed to determine the percentage of people who will enter the job:
4 - 2 = 2
4 = 100
2 = X
2 x 100/4 = X
200/4 = X
50 = X
Thus, 50% of the applicants will enter the job.
solve for X
please answer will give brainliest!!
Answer:
x=19.55
hope it help you..
Answer:
19.55
Step-by-step explanation:
x/8.5 = 2.3
x = 8.5 × 2.3
x = 85 × ⅒ × 23 × ⅒
x = 85 × 23 × ⅒ × ⅒
x = 1955 × 1/100
x = 1955/100
x = 19.55

Answer:
the book has 40 pages
Step-by-step explanation:
so he has read 90 percent and has 4 pages left. So 10 percent is 4 pages.
10 times 10 is 100. 4 times 10 is 40. The entire book is 40 pages.
10 percent equals 4 pages
20 percent percent 8 pages
30 percent is 12 pages
40 percent is 16 pages
50 percent is 20 pages
60 percent is 24 pages
70 percent is 28 pages
80 percent is 32 pages
90 percent is 36 pages
100 percent is 40 pages
13. You are buying plants and soil for your garden. The soil costs $4.00 per bag and the plants cost $10.00 each. You want to buy at least 5 plants and can spend no more than $100.00 total
Answer:
Part a) The system of linear inequalities is
y\geq 5y≥5
4x+10y\leq 1004x+10y≤100
Part b) The graph in the attached figure
Part c) A solution could be (5,7) (see the explanation)
Step-by-step explanation:
The complete question is
You are buying plants and soil for your garden. The soil cost 4.00 dollars per bag and the plants cost 10.00 each. You want to buy at least 5 plants and can spend no more than10.00each.Youwanttobuyatleast5plantsandcanspendnomorethan100
a) write a system of linear inequalities to model the situation
b) Graph the system of linear inequalities
c) Identify and interpret a solution to the system
Part a) write a system of linear inequalities to model the situation
Let
x -----> the number of bags of soil
y ----> number of plants
we know that
The word "at least" means "greater than or equal"
y\geq 5y≥5 ----> inequality A
The word "no more" means "less than or equal"
4x+10y\leq 1004x+10y≤100 ----> inequality B
Part b) Graph the system of linear inequalities
we have
y\geq 5y≥5 ----> inequality A
4x+10y\leq 1004x+10y≤100 ----> inequality B
using a graphing tool
the solution is the triangular shaded area
see the attached figure
Part c) Identify and interpret a solution to the system
we know that
If a ordered pair is a solution to the system, then the ordered pair must lie on the shaded area of the solution
i take the point (5,7)
the point (5,7) lie on the shaded area of the solution
so
is a solution of the system
That means ----> You are buying 5 bags of soil and 7 plants for your garden
Verify the solution
Remember
If a ordered pair is a solution to the system, then the ordered pair must satisfy both inequalities
Verify inequality A
7\geq 57≥5 ----> is true
so
The ordered pair (5,7) satisfy inequality A
Verify inequality B
4(5)+10(7)\leq 1004(5)+10(7)≤100
90\leq 10090≤100 ---> is true
so
The ordered pair (5,7) satisfy inequality B
therefore
The ordered pair (5,7) is a solution to the system
Four times a number is equal to three times the quantity of one more than the number. What is the number?
a. 1
b. 2
c. 3
d. 4
e. 5
Answer:
x = 3
Step-by-step explanation:
Equation: 4x = 3(1 + x)
Distribute the 3: 4x = 3 + 3x
Subtract 3x from both sides: x = 3
. The average life of a certain type of small motor is 10 years with a standard deviation of 2 years. The manufacturer replaces free all motors that fail while under guarantee. If she is willing to replace 3% of the motors that fail, how long a guarantee (in years) should she offer
Answer:
She should offer a guarantee of 13.76 years.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
The average life of a certain type of small motor is 10 years with a standard deviation of 2 years.
This means that [tex]\mu = 10, \sigma = 2[/tex]
If she is willing to replace 3% of the motors that fail, how long a guarantee (in years) should she offer?
She should offer the 100 - 3 = 97th percentile as a guarantee, so X when Z has a pvalue of 0.97, that is, X when Z = 1.88.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.88 = \frac{X - 10}{2}[/tex]
[tex]X - 10 = 2*1.88[/tex]
[tex]X = 13.76[/tex]
She should offer a guarantee of 13.76 years.

A record with a diameter of 12 inches rotates at 33 revolution per minute find the angular speed of the record in radians per second
9514 1404 393
Answer:
1.1π radians/second
Step-by-step explanation:
Each revolution is 2π radians, and there are 60 seconds in a minute. The rotation rate is ...
(33 rev/min)×(2π rad/rev)×(1 min)/(60 sec) = 66π/60 rad/sec
= 1.1π rad/sec
The angular speed is 1.1π radians per second.

Answer:
A bit of a doosy, but bare with me: f*g*h(x) = [tex]x^2+54x-12x\sqrt{x} -108\sqrt{x} +90[/tex]
Step-by-step explanation:
So explaining this is a bit awkward as well, but I can try...So
Starting from g(x) working that backwards into f(x), so...
g(x) = [tex]x-3[/tex]
f(x) = [tex](x^4+9)[/tex]
Take your g(x) and plug it into your f(x) into every x you see
f(g(x)) = [tex](x-3)^4+9[/tex] ~ I hope you can visualize this, but do you see how g(x) plugs into f(x)...
Now you still have one more step which you still need to include h(x), so
Remember h(x) = [tex]\sqrt{x}[/tex]
Now plug in your h(x) into every x you see from f(g(x)) and it should look like...
[tex](\sqrt{x} -3)^4 + 9[/tex]

Monica has a cylindrical container full of marbles. The container is shown below.
10 cm
The height of the container is approximately 12 centimeters. Which is closest to
the volume of Monica's container, in cubic centimeters?
Answer:
Area of a circle is pi * [tex]r^{2}[/tex]
then multiply that by the height
Step-by-step explanation:
diameter = 10
radius is diameter / 2
r = 10/2 = 5
A = pi * [tex]5^{2}[/tex]
A = 78.5398
height * A = volume
12 * 78.5398 = 942.477
So about 942 , answer 3 looks right :) sorry I got to your question late, send me a note , when you have a question, so I'll see :)

The measure of an angle is 37.1º, What is the measure of its complementary angle?
Answer:
52.9º
Step-by-step explanation:
complementary is when the sum of two angles is 90 degrees
to solve, simply take 37.1 and subtract it from 90:
⇒ 90 - 37.1
⇒ 52.9
help me please!!! thank you!!!
Answer:
254.47 inches squared
Step-by-step explanation:
Area of a circle is
[tex]\pi {r}^{2} [/tex]
so to find the radius we half the diameter( which here is 18 inches) which equals to 9
we replace r to 9 because that's the radius
[tex]\pi \times {9}^{2} [/tex]
which is 254.47 inches squared
-7x-4y=18
y=-5x-24
solve for x and y (show work)
Answer:
ima answer it but first how do i show the work
Step-by-step explanation:
Answer:
(-6, 6)
x=-6, y=6
Step-by-step explanation:
The easiest way to solve for this is by substitution. This means substituting y with -5x-24 in the first equation. It gives you the same variables and is easy to work with.
1. Set up your equation: -7x-4(-5x-24)=18
2. Use the distribution property: -7x+20x+96=18
3. Add like terms: 13x+96=18
4. Subtract 96 from both sides: 13x=-78
5. Divide by 13 to get x alone: x=-6
Now that we have x, we can find y much easier by plugging in -6 for x.
1. Set up your equation: -5(-6)-24=y
2. Multiply: 30-24=y
3. Subtract: 6=y
Check your answers!
-7(-6)-4(6)=18
-5(-6)-24=6
There you go! Hope this helped :)
