Answer:
30
Step-by-step explanation:
60% hombres 40% mujeres
25% mujeres saben nadar 75% mujeres no saben nadar=9 estudiante
75%= 3*25% , por lo tanto 25%=3 estudiante
total mujeres 3+9=12 estudiante =40% mujeres
60% hombres =? estudiante 40% mujeres=12estudiante
3*20=60 20*20=40 por lo tanto 20%=6 estudiante
60%=3*6=18 estudiante
Total hombres y mujeres estudiante 18+12=30

1. Cindy did an experiment. She started out with 700 bacteria cells. She found that the growth rate of the
bacteria cells was 4.3%. Create an equation for the situation that would work for any time, x. Type your
equation into Desmos to make a graph that represents her experiment.
given and, write the new function rule (equation) for function and describe (using words) the two transformations that occur between function and function.
i already got the equation for the first part: y=700(1.043^x) but i don’t understand the second part.
Answer:
See the screenshot! :)
Step-by-step explanation:
we have a exponential function of the form
y=a([tex]b^x[/tex])
where
y ---> is the population of bacteria
x ---> the number of hours
a is the initial value or y-intercept
b is the base of the exponential function
r is the rate of change
b=(1+r)
we have
a=700 bacteria
r=5%=5/100=0.05
so
b=1+0.05=1.05
substitute
y=700([tex]1.05^x[/tex])
For x=20 hours
substitute in the equation and solve for y
y=700(1.05)^20= 1,857 bacteria
Hope this helped! :)
A medication is administered with a dose of 10 milligrams. After 3 hours there are 6.5 milligrams in the patient's system. What is the half life of the medication, in hours? Round to one decimal place.
Answer:
4.8 hours
Step-by-step explanation:
The formula for half life is given as:
t½ = t × In(2)/In(No/Nt)
Where
t½ = Half life
t = time in hours = 4
No = Initial amount = 10mg
Nt = Final amount after 3 hours = 6.5 mg
t½ = 3 × In(2) /In(10/6.5)
t½ = 4.8271216522281 hours
Approximately = 4.8 hours
The half-life of the medication, in hours, is 4.8 hours.
Given that,
Medication is administered with a dose of 10 milligrams. After 3 hours there are 6.5 milligrams in the patient's system.Based on the above information, the calculation is as follows:
The following formula should be used:
[tex]= t \times ln(2)\div ln(No\div Nt)[/tex]
Here
t denotes the time in hours i.e. 4
No means the Initial amount i.e. 10mg
Nt means Final amount after 3 hours i.e. 6.5 mg
So,
[tex]= 3 \times ln(2) \div ln(10\div 6.5)[/tex]
= 4.82
= 4.8 hours
Therefore we can conclude that the half-life of the medication, in hours, is 4.8 hours.

What is the solution to the system of equation? Write you answer as a coordinate point.
Answer:
Step-by-step explanation:
Ok, so we have the equations:
7x-2y=-13
and
2y-5x=11
So first things first, we can cancel out 2y from both equations because they are common factors.
So we are left with the equations:
7x=-13
and
5x=11
So we add the two common factors and get:
12x=-24
And now we divide on both sides and get:
x=-2
Rayna paid a $200 fee to join a health club and then a $50 fee per month to use the club. The total amount of money (t) paid can be represented by the equation t = 200 + 50 m , where m represents the number of months of club use. Nora paid a $100 fee to join another health club and then a $75 fee per month to use the club, which can be represented by the equation t = 100 + 75 m . The graph below shows the fees paid by Rayna and Nora. In what month will both girls have paid an equal amount of money to their health clubs?
Answer:
the fourth month
Step-by-step explanation:
200 + 50m = 100 + 75m
subtract 100 on both sides
100 + 50m = 75m
subtract 50m on both sides
100 = 25m
divide by 25 on both sides
m = 4

Write the equation of a line in slope intercept form giving the following:
A: m=2 (0,-7)
B: (3,-4) (-2,1)
C: f(2)=6 f(0)=5
Answer:
Equation of a straight line is given as y = mx+c
m = slope or gradient or dy/dx or y2 - y1/ x2 - x1
c = intercept
y = 2x - 7
y = -x + 1
y = 2x - 10
Step-by-step explanation:
Using y = mx+c
A. m=2 y=-7 x=0
-7= 2*0 + c
-7=c
y = 2*x - 7
y = 2x - 7
B. x1=3 x2=-2 y1=-4 y2=1
m = y2 - y1/ x2 - x1
m = 1+4 / -2-3
m = 5/-5 which is equal to -1
using any value for y and x, let's use x1 and y1
-2 = -1*3 + c
-2 = -3 + c
1 = c
y = -1*x + 1
y = -x + 1
C. x1=6 x2= 5 y1= 2 y2=0
m = y2 - y1/ x2 - x1
m = 0-2 / 5-6
m = -2/-1 which is equal to 2
using any value for y and x, let's use x1and y1
2 = 2*6 + c
2 = 12 + c
-10 = c
y = 2*x -10
y = 2x - 10

How much larger is 6.3 x 10^6 than 4.9 x 10^4 ?
Answer: 625100
Step-by-step explanation:
To begin, we would start multiply both numbers one by one.
(6.3 x 10^6) - 4.9 x 10^4
6.3 x 10^6 = 6300000
4.9 x 10^4 = 49000
Now, subtract (6.3 x 10^6) and (4.9 x 10^4)
6300000. 49000
6300000 - 49000 = 6251000

What other information do you need to prove GHK ≅ KLG by SAS?
The image is a quadrilateral GHKL and a diagonal GK is drawn such that it forms two triangles GHK and KLG. Sides GL and KH are marked as congruent.
A. ∠KHG ≅ ∠GLK
B. ∠HGK ≅ ∠LKG
C. ∠GHK ≅ ∠KLG
D. ∠HKG ≅ ∠LGK
Answer: D. ∠HKG ≅ ∠LGK
Step-by-step explanation:
Given: Quadrilateral GHKL where diagonal GK is drawn such that it forms two triangles GHK and KLG.
Side GL ≅ Side KH
Now, GK is common in both triangles GHK and KLG.
and GK ≅GK
SAS congruence rule: If any two sides and the angle included between the sides of one triangle are congruent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent.
So ∠HKG must be congruent to ∠LGK ( angles between the congruent sides).
Hence, the correct option is D. ∠HKG ≅ ∠LGK
Question:
What other information do you need to prove ∆ GHK ≅ ∆ KLG by SAS?

Find f (77)
f(p)=7/11p-10:
A: f(77)=59
B: f(77)=39
C: f(77)=49
D: f(77)=67
Answer:
I don't know, the way it is typed confuses me. Is it 7/11 TIMES p-10 or is p-10 with the 11 as the denominator? but I do hope this helps:
Step-by-step explanation:
So first I subtracted 7/11 from each side:
f(p)-7/11=(7/11-7/11)p-10
Now we are left with f(4/11p)=p-10
Now to get the variable "p" on one side, I subtracted 4/11p from both sides:
f(4/11p-4/11p)=(p-4/11p)-10
Now we are left with f=7/11p-10
Now we want the "p" to be 1p so we multiply each side by the reciprocal of 7/11:
f(11/7)=(7/11*11/7)p-10
Now we have 1 4/7f=p-10
Now we subtract 4/7 from each side and get:
f=p-9 3/7
And that's as far as I could simplify it, sorry if it's wrong... lol
The required value of f (77) is 39 for the given equation. The correct answer would be an option (B).
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question, as follows:
f (p) = (7/11) p - 10
We have to determine the value of f (77) for the given equation.
As per the question, we have
f (p) = (7/11) p - 10
Substitute the value of p = 77 in the above equation,
f (77) = (7/11)(77) - 10
f (77) = 7 x 7 - 10
f (77) = 49 - 10
Apply the subtraction operation, and we get
f (77) = 39
Thus, the value of f (77) is 39.
