The system will be
f(x)=4.55x+40
g(x)=5.75x+10
Both company 1 and 2 charge $153.75 for cleaning 25 garment
Step-by-step explanation:
Equation 1
[tex]\frac{85.50-62.75}{10-5} =\frac{22.75}{5}=4.55[/tex]
y-62.75=4.55(x-5)
y-62.75=4.55x-22.75
c(n)=4.55x + 40
Equation 2
[tex]\frac{67.50-38.75}{10-5}=\frac{28.75}{5}=5.75[/tex]
y-38.75=5.75(x-5)
y-38.75=5.75x-28.75
c(n)=5.25x + 10
The system will be
f(x)=4.55x+40
g(x)=5.75x+10
30=1.2x
x=25
f(x) when x=25
f(x)=4.55x+40
f(25)=4.55(25)+40
f(25)=113.75+40
f(25)=153.75
Both company 1 and 2 charge $153.75 for cleaning 25 garments.
Let U = {q, r, s, t, u, v, w, x, y, z} A = {q, s, u, w, y} B = {q, s, y, z} C = {v, w, x, y, z}. List the elements in the set: A ∪ C Group of answer choices
Answer:
[tex]A \cup C=\left \{ \text{q, s, u, v, w, x, y, z} \right \}[/tex]
Step-by-step explanation:
Given: [tex]\text{U}=\left \{\text{q, r, s, t, u, v, w, x, y, z} \right \}[/tex], [tex]\text{A}=\left \{\text{q, s, u, w, y} \right \}[/tex], [tex]\text{B}=\left \{\text{q, s, y, z} \right \}[/tex],
[tex]\text{C}=\left \{\text{v, w, x, y, z} \right \}[/tex].
To find: The elements in the set [tex]A \cup C[/tex].
Solution:
We have,
[tex]\text{U}=\left \{\text{q, r, s, t, u, v, w, x, y, z} \right \}[/tex]
[tex]\text{A}=\left \{\text{q, s, u, w, y} \right \}[/tex]
[tex]\text{B}=\left \{\text{q, s, y, z} \right \}[/tex]
[tex]\text{C}=\left \{\text{v, w, x, y, z} \right \}[/tex]
Now, [tex]A \cup C[/tex] will contain all the elements in the set [tex]A[/tex] and all the elements in set [tex]C[/tex].
So, [tex]A \cup C=\left \{ \text{q, s, u, v, w, x, y, z} \right \}[/tex].
Hence, [tex]A \cup C=\left \{ \text{q, s, u, v, w, x, y, z} \right \}[/tex].

Aubree invested $16,000 in an account paying an interest rate of 5.6% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest tenth of a year, for the value of the account to reach $45,600?
Answer:
t=18.7
Step-by-step explanation:
After 19.2 year the account reach $45,600.
What is Interest?The cost of borrowing money is called interest, and it is typically stated as a percentage, such as an annual percentage rate (APR). Lenders may charge interest to borrowers for using their funds, or borrowers may charge interest to lenders for using their funds.
We have,
P =$16, 000
R= 5.6%
Future value = $45, 600.
Now, using
16,000 (1 + 5.6%[tex])^x[/tex] = 45,600
(1 + 5.6%[tex])^x[/tex] = 2.85
Taking log on both side we get
x log (1.056) = log (2.85)
x= 19.2
Thus, the time taken is 19.2 years.

Sally rides her bike 164.45 miles in two weeks. She averaged 12.65 miles per hour each time she rode. How many hours did it take her to ride 164.45 miles?
Answer: It took 13 hours by her to ride 164.45 miles.
Step-by-step explanation:
Total distance = 164.45 miles
Average distance traveled = 12.65 miles per hour (speed)
[tex]Time = \dfrac{Distance}{Speed}[/tex]
[tex]Time = \dfrac{164.45}{12.65}=\dfrac{16445}{1265}\\\\=13\text{ hours}[/tex]
Hence, it took 13 hours by her to ride 164.45 miles.

9514 1404 393
Answer:
3479
Step-by-step explanation:
Each year, the population is multiplied by 1 - 4.5% = 0.955. After 25 years, the population will have been multiplied by 0.955^25 ≈ 0.316289. At that time, the population will be approximately ...
11000 · 0.316289 ≈ 3479

7. Se llevó a cabo una encuesta de mercado para calcular la proporción de amas de casa que reconocerían el nombre de la marca de un limpiador a partir de la forma y color del envase. De las 1 400 amas de casa de la muestra, 420 identificaron la marca por su nombre. a. Calcule el valor de la proporción de la población. b. Construya el intervalo de confianza de 99% de la proporción poblacional. c. Interprete sus conclusiones.
Answer:
a) El valor de la proporción de la población = 0.3
b) El intervalo de confianza de 99% de la proporción poblacional = [0.2685, 0.3315]
c) Interprete sus conclusiones.
De los cálculos anteriores, podemos concluir que tenemos un 99% de confianza en que el parámetro de población se encuentra entre 0.2685 y 0.3315 ".
Step-by-step explanation:
a) Halla el valor de la proporción de la población.
El valor de la proporción se calcula mediante la fórmula
p = x / n
donde x = 420
n = número de muestras = 1400
Proporción (p) = 420/1400
= 60/200 = 30/100 = 3/10
= 0.3
b) Construya el intervalo de confianza del 99% para la proporción de población.
La fórmula para el intervalo de confianza para la proporción de población =
p ± z × √p (1 - p) / n
p = 0.3
z = puntuación z para un intervalo de confianza del 99% = 2.576
n = 1400
Por lo tanto:
Intervalo de confianza del 99% = 0.3 ± 2.576 × √0.3(1 - 0.3) / 1400
= 0.3 ± 2.576 × √0.3× 0.7 / 1400
= 0.3 ± 2.576 × 0.0122474487
= 0.3 ± 0.0315494279
Intervalo de confianza del 99% =
0.3 - 0.0315494279
= 0.2684505721
Aproximadamente ≈ 0.2685
0.3 + 0.0315494279
= 0.3315494279
Aproximadamente ≈ 0.3315
Por lo tanto, el intervalo de confianza del 99% = [0.2685, 0.3315]
c) Interprete sus conclusiones.
De los cálculos anteriores, podemos concluir que tenemos un 99% de confianza en que el parámetro de población se encuentra entre 0.2685 y 0.3315 ".

Sierra has a recipe she wants to make. She has to use eggs and sticks of butter. The ratio for these ingredients is 12 to 4 to make 4 batches. What will the equivalent ratio be if she wants to make 8 batches?
Answer:
24:8
Step-by-step explanation:
Given the following data;
Batch = eggs + sticks of butter
4 batches = 12:4
8 batches = 2 * 4 batches
Therefore, 8 batches = 2*(12:4)
8 batches = 24:8
Hence, the equivalent ratio Sierra would use if she wants to make 8 batches is 24 eggs to 8 sticks of butter.
Answer:
Step-by-step explanation:
the answer is 24:8

I need help. I have been searching for the answer but I cannot find the correct one. Elena rode her bike 2 miles in 10 minutes and 1 mile in 5. How many miles if it only took her 1 minute? Like how many miles would she have rode in 1 minute?
Answer:
0.2 miles
Step-by-step explanation:
From the above question:
2 miles = 10 minutes
Hence:
10 minutes = 2 miles
1 minute = x miles
Cross Multiply
10 minutes × x miles = 2 miles × 1 minute
x miles = 2 miles × 1 minute/10 minutes
x miles = 0.2 mile
Hence in 1 minute it would take her 0.2 miles

The angle of the elevation from the top of a 95 Todd building into a hot air balloon in the sky and 76° if the horizontal distance between the building in a horrible Luna is 354 feet find the height of a hot air balloon
Answer:
The height of the hot air balloon is 1514.54 feet approximately.
Step-by-step explanation:
Consider the provided information.
The angle of elevation from the top of a 95-foot tall building to a hot air balloon in the sky is 76. If the horizontal distance between the building and the hot air balloon is 354 feet, find the height of the hot air balloon
The figure is shown below:
Let the height of the balloon is AD, the height of the building is BC.
Draw a line BE parallel to CD.
Therefore, AD=x+95, BC=95 and BE=CD=354 ft
Now in triangle [tex]ABE[/tex].
[tex]\tan\theta=\dfrac{\text{Opp}}{\text{Adj}}[/tex]
[tex]\tan76^{\circ}=\dfrac{AE}{BE}[/tex]
[tex]AE\approx 4.01\times 354[/tex]
[tex]AE\approx 1419.54[/tex]
The height air balloon is 1419.54+95 =1514.54 ft
Hence, the height of the hot air balloon is 1514.54 feet approximately.

Answer:
1. yes
2. no
Step-by-step explanation:
We can label the equations [1] and [2] to make the transformations to the equivalent system easier to describe.
1. The equivalent system is [1] +[2] and 2×[1]. Both of these are described as allowed transformations.
[1] +[2] is (-x +2y) +(-3x +9y) = (10) +(-15) ⇒ -4x +11y = -5
2×[1] is 2(-x +2y) = 2(10) ⇒ -2x +4y = 20
These resulting equations match the ones proposed for the equivalent system.
yes, the systems are equivalent
__
2. The first equation of the proposed "equivalent" system is [1] +[2]. The second equation has no relation to the equations of the given system.
[1] +[2] = (-2x +3y) +(-11x -13y) = (14) +(-6) ⇒ -13x -10y = 8
no, the systems are not equivalent
(This is also shown in the attached graph. The original system is in red; the "equivalent" system is in green. Equivalent systems have the same solution. These do not.)
