Two people are traveling and need to exchange the currency of their native country for the currency of the country they are visiting. drag each exchange to match the ratio of currency to currency in each category.
Answer:
The solution is shown in attached figure.
Step-by-step explanation:
In table 1,
US currency (Dollars) Foreign currency
50.00 31.50
The foreign currency per US dollar is
[tex]\frac{31.50}{50}=0.63[/tex]
Therefore 0.63 is not equal to the exchange rate of Mexican peso and euro.
In table 2,
US currency (Dollars) Foreign currency
20.00 14.60
The foreign currency per US dollar is
[tex]\frac{14.60}{20}=0.73[/tex]
Therefore 0.73 is equal to the exchange rate of euro.
In table 3,
US currency (Dollars) Foreign currency
25.00 18.25
The foreign currency per US dollar is
[tex]\frac{18.25}{25}=0.73[/tex]
Therefore 0.73 is equal to the exchange rate of euro.
In table 4,
US currency (Dollars) Foreign currency
40.00 724.80
The foreign currency per US dollar is
[tex]\frac{724.80}{40}=18.12[/tex]
Therefore 18.12 is equal to the exchange rate of Mexican peso.
In table 5,
US currency (Dollars) Foreign currency
15.00 271.80
The foreign currency per US dollar is
[tex]\frac{271.80}{15}=18.12[/tex]
Therefore 18.12 is equal to the exchange rate of Mexican peso.

Which of the following fuction is best represented by the scatter plot?
F(x)=9-10.3x
F(x)=-10.3+9x
F(x)=-9+10.3x
F(x)=10.3-9x
Answer:
F(x)=-9+10.3x
Step-by-step explanation:
Given:
(1,0)
(2,10)
(3,20)
(4,30)
(5,40)
(6,50)
(7,65)
(8,70)
(9,80)
(10,90)
F(x)=9-10.3x and F(x)=10.3-9x cannot be the function of given scatter plot since the slope in these functions are negative
So, The equation of line can be F(x)=-10.3+9x or F(x)=-9+10.3x
Refer the attached figure.
Using desmos calculator
We conclude that the function is best represented by the scatter plot is [tex]F(x)=-9+10.3x[/tex]
An animal shelter has a total of 350 animals comprised of cats, dogs, and rabbits. If the number of rabbits is 5 less than one-half the number of cats, and there are 20 more cats than dogs, how many cats are at the shelter?
To find the number of cats at the animal shelter, we can set up and solve a system of equations using the given information. In this case, the number of dogs is 126 and the number of cats is 146.
Explanation:To solve this problem, let's assign variables to represent the number of cats, dogs, and rabbits at the shelter. Let's say the number of cats is 'c', the number of dogs is 'd', and the number of rabbits is 'r'.
From the given information, we can form three equations:
The total number of animals is 350: c + d + r = 350The number of rabbits is 5 less than one-half the number of cats: r = (1/2)c - 5There are 20 more cats than dogs: c = d + 20Using these equations, we can solve for the value of 'c' (the number of cats).
By substituting the value of 'c' from equation 3 into equation 2, we get:
r = (1/2)(d + 20) - 5
Now, we substitute the values of 'c' and 'r' from equations 3 and 1 into equation 1:
(d + 20) + d + ((1/2)(d + 20) - 5) = 350
Simplifying this equation, we get:
2d + (1/2)d + 35 = 350
Combining like terms, we have:
4d + d + 70 = 700
Simplifying further, we find:
5d + 70 = 700
Subtracting 70 from both sides of the equation, we get:
5d = 630
Dividing both sides by 5, we find that d = 126. Therefore, there are 126 dogs at the shelter.
Finally, by substituting the value of d back into equation 3, we find:
c = 126 + 20 = 146. Thus, there are 146 cats at the shelter.

A $28,000 car loan is used to purchase a new car. The loan is for 6 years and has a 5.75% APR. Use the amortization formula to determine the amount of the monthly payments.
Kurt wants to have $25,000 in an investment account four years from now. the account will pay 0.2 percent interest per month. if he saves money every month, starting one month from now, how much will he have to save each month to reach his goal
Kurt will have to save an amount of $496.75 each month.
What is Compound Interest?Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.
Final amount of the account, A = $25,000
Interest rate, r = 0.2% = 0.002
Number of years, t = 4 years
Interest compounded monthly, so n = 12
Annuity can be found using the formula,
Annuity = 25,000 ÷ {[(1 + 0.002)^(12×4) - 1] / 0.002}
= 25,000 ÷ {[(1.002)⁴⁸ - 1] / 0.002}
= 496.75
Hence the amount Kurt needs to save each month is $496.75.

An object is dropped off a building that us 144 feet tall. After how many seconds does the object hit the ground? (s= 16t^2)
Answer:
After 3 seconds the object hit the ground.
Step-by-step explanation:
An object is dropped off a building that us 144 feet tall. After how many seconds does the object hit the ground.
Given that displacement, s = 16t²
To reach ground displacement should be 144 feet.
That is
s = 16t² = 144
t² = 9
t = 3 seconds.
After 3 seconds the object hit the ground.
G study find the exact value of each of the remaining trigonometric functions cos theta=4/5 270< theta
Given that cos theta is 4/5 within the 270 to 360-degree range, sin(theta) is -3/5, tan(theta) is -3/4, sec(theta) is 5/4, csc(theta) is -5/3, and cot(theta) is -4/3.
Explanation:The question indicates that we are dealing with trigonometry and specifically asks for the remaining trigonometric functions given that cos theta = 4/5 and theta is in the range of 270o to 360o.
This implies that theta is in the fourth quadrant where cosine is positive, and the other trigonometric functions can have different signs.
Since we have the cosine of theta, we can use the Pythagorean identity to find the sine of theta. The identity states that in2(theta) + cos2(theta) = 1.
Plugging in the given cosine value, we have:
sin2(theta) + (4/5)2 = 1
sin2(theta) = 1 - 16/25
sin2(theta) = 9/25
sin(theta) = ±√(9/25) = ±3/5
However, since theta is in the fourth quadrant, the sine is negative, and therefore we find:
sin(theta) = -3/5
For the tangent of theta, we use the definition tan(theta) = sin(theta)/cos(theta), which yields:
tan(theta) = (-3/5) / (4/5) = -3/4
The values of the other three trigonometric functions (secant, cosecant, and cotangent) are the reciprocals of the three we just calculated:
sec(theta) = 1/cos(theta) = 5/4
csc(theta) = 1/sin(theta) = -5/3
cot(theta) = 1/tan(theta) = -4/3
a culture started with 6,000 bacteria. After 4 hours, it grew to 6,600 bacteria. Predict how many bacteria will be present after 10 hours. round your answer to the nearest whole number.
P = 6,600
A = 6,000
t = 4
k = ?
6600 = 6000e^(4k)
6600/6000 = e^(4k)
1.1 = e^(4k)
Take the natural log of both sides.
ln 1.1 = 4k ln e (remember that ln e = 1)
ln 1.1 = 4k
(ln 1.1) / 4 = k
k = 0.0238
Bacteria after 10 hours.
P = 6000e^(0.0238*10)
= 6000e^0.238
= 7612
Therefore, the bacteria will grow to 7612 after 10 hours.

The expected value of the roulette game red or black is -$0.62 per game, indicating an expected average loss.
Explanation:The expected value of the roulette game red or black can be calculated by multiplying the probabilities of winning and losing by their corresponding outcomes. In this case, the probability of winning ($10) is 19/37, and the probability of losing ($-10) is 18/37. Multiply these probabilities by their corresponding outcomes and subtract to get the expected value:
Expected value = (19/37 * $10) + (18/37 * -$10) = -$0.54 + (-$0.54) = -$0.62

What is 18a and 12ab's GCF
Answer:
6a
Step-by-step explanation:
18a = 2 · 3² · a

Factors common to both lists are 2, 3, a, so the GCF is 2·3·a = 6a.
A certain species of tree grows an average of 4.2 cm per week. write an equation for the sequence that represents the weekly height of this tree in centimeters if the measurements begin when the tree is 200 centimeters tall.
Average growth rate = 4.2 cm/week.
So, common difference d = 4.2
The height of the tree a0 = 200 centimeters.
The height of the tree after end of the first week a₁ = 200 + 4.2 = 200 + 4.2(1)
The height of the tree after end of the second week a₂ = 200 + 4.2 + 4.2 = 200 + 4.2(2).
The height of the tree after end of the third week a3 = 200 + 4.2 + 4.2 + 4.2 = 200 + 4.2(3).
The height of the tree after the end of the nth week an = 200 + 4.2(n).
The equation is a_n = 200 + 4.2(n).
