Answer:
2:5
it may be faster to google it
Answer:
Required ratio is 2:5.
Step-by-step explanation:
Given that number of female nurses = 250
Given that number of male nurses = 100
Now we need to find about what is the ratio of male nurses to female nurses.
So we just need to divide number of male nurses by the number of female nurses. That means divide 100 by 250. We get:
[tex]\frac{male}{female}=\frac{100}{250}[/tex]
[tex]\frac{male}{female}=\frac{10}{25}[/tex]
[tex]\frac{male}{female}=\frac{2}{5}[/tex]
Hence required ratio is 2:5.
Amber bought a condominium at a time when prices were at their highs. She paid $200,000. Since then, the market value has decrease by 5% per year. Write an exponential depreciation equation to model this situation. Approximately when will Amber's condominium be worth less than $140,000?
Answer:
$140,000(1 - .05)^t
Step-by-step explanation:
you have your total amount $140,000
it is decreased by 5% go behind the number and move two decimal points and you get .05
since is decreasing it would be 1 subtracted by ,05
$140,000(1 - .05)^t
"t" is the years it would be depreciated by
I do not see years but by knowledge i would say it is decreasing
Answer:
Since, the exponential decay function,
[tex]A=P(1-r)^t[/tex]
Where,
P = initial value,
r = rate per period,
t = number of periods,
Here, P = $ 200,000, r = 5% = 0.05,
Thus, the value of the condominium would be,
[tex]A=200000(1-0.05)^t=200000(0.95)^t[/tex]
Which is the required equation.
If A < 140,000
[tex]200000(0.95)^t < 140000[/tex]
By the graphing calculator.
[tex]t< 6.95364[/tex]
Hence, about after 7 years the condominium will be worth less than $140,000.
consider the inequality-5(x+7)<-10 write an inequality representing the solution for x
Answer:
x > -5Step-by-step explanation:
-5(x + 7) < -10 use the distributive property a(b + c) = ab + ac
(-5)(x) + (-5)(7) < -10
-5x - 35 < -10 add 35 to both sides
-5x < 25 change the signs
5x > - 25 divide both sides by 5

Rena pushes the elevator button but the elevator does not move the mass limit for the elevator is 450 kg But Reena and her load of identical Packages mass A total of 620 KG each package has a mass of 37.4 KG
Answer:
1) 620- 37.4p≤450
2) 5
Step-by-step explanation:
Total weight of rena and packages = 620 kg
lift limitation= 450 kg
mass of each load= 37.4 kgs
As the mass limit for the elevator is 450 kg therefore the from the Total weight of rena and packages (620 kgs) rena needs to subtract weight of some number of packages (p x 37.4)
hence
620- 37.4p≤450
2)
Solving for minimum whole number of packages p, rena needs to remove to meet the elevator limitation:
620- 37.4p≤450
37.4p≤-450+620
37.4p≥170
p≥4.5

Editor needs six cookies and 2 brownies for every 4 plates he makes for a bake sale cookies and brownies into the box to show how many editor needs for ten plates
Answer: 15 cookies and 5 brownies will be required.
Step-by-step explanation:
Given in the question is Eder needs 6 cookies and 2 brownies for 4 plates.
We have to calculate the cookies and brownies required for 10 plates.
Let's first calculate the cookies by unitary method.
⇒ 4 plates required cookies = 6 cookies
⇒ 1 plate will require cookies = 6/4
⇒ 10 plates will require cookies = 6×10/4 = 15
Similarly we will calculate the brownies.
⇒ 4 plates required number of brownies = 2
⇒1 plate will require = 2/4 brownies
⇒10 plates will require = 2×10/4 = 5 brownies
⇒Therefore 15 cookies and 5 brownies will be required for 10 plates.

For 4 plates, an editor needs 1.5 cookies and 0.5 brownies. Thus, for ten plates, they will require 15 cookies and 5 brownies.
Explanation:Let's start by determining the amount of cookies and brownies the editor needs for 4 plates. As per the given information, the editor needs 6 cookies and 2 brownies for every 4 plates. Therefore, for each plate, the editor will need to have 1.5 cookies (6/4 = 1.5) and 0.5 brownies (2/4 = 0.5).
Now, let's compute how much this would translate to if we have ten plates. Using the ratio we determined earlier, for ten plates the editor would need:
15 Cookies (1.5 cookies per plate * 10 plates)5 Brownies (0.5 brownies per plate * 10 plates)This is the simplest way to figure out how many cookies and brownies are needed for a given number of plates, provided you know how much is needed per plate.

Joan has a gym gift card worth $100. Each time she visits the gym. $12 is deducted from the amount remaining on the gift card. Which equation can be used to determine the amount of the money (m) , in dollars, remaining on the gift card after joan visits the gym d times
The equation to calculate the remaining money on Joan's gym gift card after d gym visits is m = 100 - 12d.
Explanation:To determine the amount of money (m), in dollars, remaining on Joan's gym gift card after she visits the gym d times, you can use a simple linear equation.
Since she starts with $100 on the card, and each gym visit costs $12, you subtract $12 for each visit from the initial amount. The equation that represents this situation is m = 100 - 12d.
Here, d is the number of times she visits the gym, and m is the money remaining on the card.

f(x)=2x and g(x)=2x+3,what is the value of f(g(-8))
Answer:
f(g(-8)) = -26
Step-by-step explanation:
Given:
f(x)=2x and g(x)=2x+3
Required:
f(g(-8))=?
Solution:
First we will find g(-8)
g(x) = 2x+3
g(-8)= 2(-8)+3
= -16 + 3
= -13.
so, g(-8) = -13
Now, for calculation f(g(-8)) we can put the value of g(-8) i.e, -13
so, f(x) = 2x
f(-13) = 2(-13)
= -26
so, f(-13) = -26
and f(g(-8)) = -26

Use addition to solve the linear system of equations. Include all of your work in your final answer. 3x-y=6 and y=x-4
Answer:
x = 1, y = -3
Step-by-step explanation:
So, we have two equations to start with: 3x-y=6 and y = x-4, we want to resolve the equations by addition.
We sum up the left sides of the equations together and the right sides together, and simplify, we have:
3x - y + y = 6 + x - 4
3x = 2 + x ==> 2x = 2 ==> x = 1
To find y, we place the value of x in any of the two equations:
y = x - 4 = 1 - 4 = -3
You verify that the solution is valid by entering the values of x and y in the other equation:
3x - y = 6 becomes
3 (1) - (-3) = 6
3 + 3 = 6
Answer:
x = 1 and y = -3
Step-by-step explanation:
The given linear equations are,
3x - y = 6 and y = x - 4
To solve the system of equations
Let 3x - y = 6 -----(1)
y = x - 4
x - y = 4 ----(2)
(2) * -3 ⇒ -3x + 3y = -4 ----(3)
(2) + (3) ⇒
3x - y = 6
-3x + 3y = -12
0 +2y = -6
y = -6/2 = -3
x - y = 4
x = 4 + y = 4 + -3 = 1
x = 1 and y = -3

The median of the data set [1, 2, 6, 7, 8, 9.4, 9.9, 9.9] is not 9.4, but instead is 7.5, which is calculated by getting the average of the two middle values, in this case, 7 and 8.
Explanation:The given set of data is: [9.4, 9.9, 9.9, 8, 7, 6, 1, 2]. The first step is to put the data in numerical order, so we have [1, 2, 6, 7, 8, 9.4, 9.9, 9.9]. The median is the middle value in an ordered data set. Since this set has an even number of data values (8), the median is calculated as the average of the two middle values. Here, the middle values are 7 and 8. Therefore, to find the median, we add these two values together and divide by 2. Hence, 7 + 8 = 15, and 15 divided by 2 equals 7.5. Therefore, the median of this data set is 7.5, not 9.4.
