Production shows that only 3 of the first 10 phones are working which is 30% of the phones describe how the percentage other working phones changes if the 11th and 12th phone won't work correctly
Answers
Answer:
If you have 10 phones, this is the 100%
then:
10 = 100%
Now we know that only 3 of them work correctly, then the percentage of pones that works correctly can be related to:
3 = X%
To find the value of X%, we can take the quotient of the equations:
3 = X%
and
10 = 100%
We ge:
(3/10) = (X%/100%)
We solve this for X and we get:
(3/10)*100% = X% = 30%
As we already know.
Now let's see how this percentage changes if we add more phones that do not work correctly.
Now we add another phone that does not work, so we have a total of 11 phones and 3 of them work.
then:
3 = X%
11 = 100%
The quotient is:
(3/11) = (X%/100%)
(3/11)*100% = X% = 27.3%
If we add another phone, now we have 12 phones and only 3 of them works, then 12 is the 100%, and we have the equations:
3 = X%
12 = 100%
Then we get:
(3/12) = X%/100&
(3/12)*100% = X% = 25%

x+(y+1) divided by 5
Answers
Answer:
uhm so you'd assume y is more than 5 so maybe try x +(7+1) /5
now do x + 8 /5. x must be like 7 so
x= 7 and y= 7 so it is 7 + (7+1) divided by 5 which is 3 I believe
simplifying it just as is is more like x + (y+1) / 5

Answer:
f(n) = 2 × [tex]3^{n-1}[/tex]
Step-by-step explanation:
In order to write an explicit rule for a geometric function, you need to know the common ratio; you can find the common ratio by dividing two consecutive terms:
6 ÷ 2 = 3, 18 ÷ 6 = 3, 54 ÷ 18 = 3, etc..
Now you know the common ratio is 3. At this point you can write your explicit function following the rule f(n) = [1st term] × [common ratio]^(n-1):
f(n) = 2 × 3^(n-1)
A sample of a radioactive isotope had an initial mass of 360 mg in the year 1998 and
decays exponentially over time. A measurement in the year 2004 found that the
sample's mass had decayed to 270 mg. What would be the expected mass of the
sample in the year 2011, to the nearest whole number?
Answers
Answer:
193 mg
Step-by-step explanation:
Exponential decay formula:
[tex]A_t = A_0e^r^t[/tex]where Aₜ = mass at time t, A₀ = mass at time 0, r = decay constant (rate), t = timeOur known variables are:
1998 to the year 2004 is a total of t = 6 years.The sample of radioactive isotope has an initial mass of A₀ = 360 mg at time 0 and a mass of Aₜ = 270 mg at time t.Let's solve for the decay constant of this sample.
[tex]270=360e^-^r^(^6^)[/tex][tex]270=360e^-^6^r[/tex] [tex]\frac{3}{4} =e^-^6^r[/tex][tex]\text{ln} (\frac{3}{4} )= \text{ln}(e^-^6^r)[/tex] [tex]\text{ln} (\frac{3}{4} )=-6r[/tex] [tex]r=-\frac{\text{ln}\frac{3}{4} }{6}[/tex] [tex]r=0.04794701[/tex]Using our new variables, we can now solve for Aₜ at t = 7 years, since we go from 2004 to 2011.
Our new initial mass is A₀ = 270 mg. We solved for the decay constant, r = 0.04794701.
[tex]A_t=270e^-^(^0^.^0^4^7^9^4^8^0^1^)^(^7^)[/tex] [tex]A_t=270e^-^0^.^3^3^5^6^2^9^0^7[/tex][tex]A_t=193.01982213[/tex]The expected mass of the sample in the year 2011 would be 193 mg.
12x^2-36x=0 solve for x
solve for x
Answers
Answer:
x = 0 or x = 3
Step-by-step explanation:
This is a quadratic equation, but because the constant term is zero, we can speed up the solution by factoring 12x^2 - 36x = 0:
12(x^2 - 3x) = 0, or
12(x)(x - 3) = 0
Thus, either x = 0 or x = 3

∠ XMN = 50°
Step-by-step explanation:
∠ XNM and ∠ XKL are alternate angles and are congruent, then
∠ XNM = 35°
The sum of the 3 angles in a triangle = 180° , so
∠ XMN = 180° - (95 + 35)° = 180° - 130° = 50°

Geometry Angle of elevation/depression
Answers
Answer:
m∠ACB = 49.88°
Step-by-step explanation:
From the figure attached,
Measure of wire AC attached to the top 'C' of the building BC = 340 m
Horizontal distance between the base 'B' of the building and point A = 260 m
Angle of depression = ∠ACB
By applying sine rule in the given triangle,
sin(∠ACB) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{AB}{BC}[/tex]
= [tex]\frac{260}{340}[/tex]
m∠ACB = [tex]\text{sin}^{-1}(764706)[/tex]
= 49.88°

Someone help and please make sure it’s right
Answers
Answer:
20°
Step-by-step explanation:
Look at the attached photo.
∠a and ∠e are equal because they are vertical angles.
So, m∠a = 110°
Then, ∠f is an exterior angle to angles a and c. So,
m∠f = m∠a + m∠c
Substitute and solve.
130 = 110 + m∠c
m∠c = 20°
Then, ∠c and ∠d are vertical angles so they are equal.
m∠c = m∠d
m∠d = 20°
I hope this helps! Feel free to ask any questions!
