About how much will he save in interest over the course of a year if he transfers his balance to a credit card with an APR of 16.5%, compounded monthly. (Assume that Jalen makes no payments or new purchases during the year, and ignore any possible late payment fees.)

Second Jet Sky Company
[tex]y=23.00+2.50x[/tex] ---------> equation [tex]2[/tex]

For 4 hours of booking, the charges paid to both the companies should be same. And the charge will be $ 30.
Let x be the number of hours of booking per jet ski.
First company charges $24.00 plus $2.25 per hour to rent a jet ski.
So, the total cost paid for x hours to the first company will be,
[tex]C_1=24+2.25x[/tex]
Second company charges a fee of $23.00 plus $2.50 per hour to rent the same jet ski.
So, the total cost paid for x hours to the second company will be,
[tex]C_2=23+2.5x[/tex]
Now, the charge paid to both the companies should be same. For this condition, the number of hours of booking per jet ski should be,
[tex]C_1=C_2\\24+2.25x=23+2.5x\\1=0.25x\\x=4[/tex]
Therefore, for 4 hours of booking, the charges paid to both the companies should be same. And the charge will be,
[tex]24+2.25\times4=\$33[/tex].

Triangle is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
The other angles in the isosceles triangle are 40°.
Option D is the correct answer
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Isosceles triangle:
One angle = 100°
We know that,
In an isosceles triangle, there are two equal sides and two equal angles opposite to the equal sides.
The sum of the three angles in the isosceles triangle is 180.
We already have,
One angle = 100°
The other two should be equal.
The sum should give us 180°.
Now,
40 + 40 = 80
100 + 80 = 180°
Thus,
The other angles in the isosceles triangle are 40°.

On a family trip, 100 miles were traveled at a rate of 60 miles per hour and another 30 miles at 40 miles per hour , what is the average speed for this trip
Answers
here total distance = 100+30 = 130 miles
time = distance / speed
time for step 1 = t1 = 100/60 = 1.6667 hours
time for step 2 = t2 = 30/40 = 0.75 hours
so total time = t = t1+t2 =2.416667hours
put values of distance and time in equation (i) we get
average speed = 130 / 2.416667 = 53.79 = 53.8 miles per hour
The average speed for the trip is calculated by using the formula of total distance divided by total time. For a total distance of 130 miles and total time of 2.42 hours, the average speed is approximately 53.72 mph.
Explanation:In order to find the average speed for the entire trip, we need to use the formula which is total distance travelled divided by the total time taken. The total distance travelled is 100 miles at 60mph plus 30 miles at 40mph, which results in 130 miles.
Now, to find the total time taken, we divide the distance travelled by the speed, which is 100 miles at 60mph results in 1.67 hours and 30 miles at 40mph results in 0.75 hours. Hence, the total time taken is the sum of these two times which is 2.42 hours.
Applying the formula for average speed, i.e., total distance divided by total time, we get 130 miles divided by 2.42 hours results in approximately 53.72 mph which is the average speed for the trip.

Deon drove 408 miles using 16 gallons of gas. At this rate, how many miles would he drive using 11 gallons of gas?
Answers
By setting up a ratio based on the known miles per gallon, we can determine that Deon would be able to drive 281.5 miles using 11 gallons of gas.
Explanation:This problem can be solved by setting up a proportion to find out how many miles Deon would drive using 11 gallons of gas. First, we know that Deon can drive 408 miles with 16 gallons of gas. This forms a ratio of 408/16 which simplifies to 25.5. This means Deon can drive 25.5 miles for every gallon of gas. Using this, we can determine how far he would travel with 11 gallons by multiplying the miles per gallon (25.5) by 11.
Therefore, Deon would drive 281.5 miles using 11 gallons of gas.

C=(−2,0), A=(−1,0), T=(−4,1)
Answers
the answer would be b. C=(2,0), A=(0,1), T=(1,4)
all x's move 2 to the right and no change in y
Solution: If a shape is being translated neither it's shape nor size changes.When we translate a shape we just move a shape or geometrical figure by certain distance either horizontally or vertically or both horizontally and vertically.
Coordinates of Triangle CAT is →C(0,0), and A(-2,1), and T(-1,4).
In option (a) vertices C has not been translated , but A and T are translated.Which is Untrue because we have to move all the vertices by same value. But x and y can have different value.
In option (b) all the coordinates C,A,and T is being translated along→ x by 2 units , horizontally right, but not translated in vertical direction.
C(0,0)⇒C(0+2,0+0)→C(2,0)
A(-2,1)⇒C(-2+2,1+0)→C(0,1)
T(-1,4)⇒C(-1+2,4+0)→C(1,4)
In option C, Coordinates of A and B are changed but not of C, So in this case translation can't happen.
In option D , C is being translated 2 units horizontally left , but amount of translation in A and T are different.
So , Option (b) is true.
On average, at least 25,000 pieces of luggage are lost or misdirected each day by United States airlines. Of these, 98% are located by the airlines within 5 days. From a given day’s lost luggage, at least how many pieces of luggage are still lost after 5 days?
Answers
To find the number of luggage still lost after 5 days, at least 2% of the given day's lost luggage will still be lost after 5 days.
Explanation:To find the number of luggage still lost after 5 days, we can use the concept of complementary events.
Since 98% of lost luggage is located by the airlines within 5 days, that means 2% of the lost luggage is still not located.
Therefore, at least 2% of the given day's lost luggage will still be lost after 5 days.

Label the sides as shown in the image attachment.
P = horizontal leg (opposite of angle x; adajcent to angle y)
Q = vertical leg (opposite of angle y; adajcent to angle x)
R = hypotenuse (longest side; always opposite the 90 degree angle)
Use the definitions of sine and cosine to say...
sin(Angle) = opposite/hypotenuse
sin(x) = P/R
and
cos(angle) = adjacent/hypotenuse
cos(y) = P/R
Notice how sin(x) = cos(y). This is true any time x+y = 90 which is the case here (x and y are complementary angles). A more specific example is sin(30) = cos(60) which are both equal to 1/2 or 0.5
Since sin(x) = cos(y), this means sin(x)/cos(y) = 1 as any expression divided by itself is equal to 1. Keep in mind that cos(y) cannot equal zero.
This is why choice D is the final answer.
side note: something like cos(x)/sin(y) or sin(y)/cos(x) or similar are all equal to 1 as long as x+y = 90

Explanation:The p-value, in statistics, measures the probability of obtaining results as extreme or more extreme than the observed data, assuming the null hypothesis is true. A smaller p-value suggests stronger evidence against the null hypothesis, typically indicating statistical significance and supporting the alternative hypothesis.

you find a fossilized animal footprint in montana. One footprint is round and has a diameter of 42cm. what is the are of the footprint?
Answers
To find the area of a round footprint with a diameter of 42 cm, you use the formula for the area of a circle, A = πr². The radius is 21 cm, so the area is approximately 1382.74 cm².
To find the area of a round footprint, you use the formula for the area of a circle, which is πr², where r is the radius of the circle.
First, find the radius by dividing the diameter by 2. In this case, 42 cm / 2 = 21 cm.Next, use the area formula: area = π x (radius)². So, area = π x (21 cm)².Calculate the result: area = π x 441 cm².Using the approximation π ≈ 3.14, the area ≈ 3.14 x 441 cm².The final area ≈ 1382.74 cm².Therefore, the area of the fossilized footprint is approximately 1382.74 cm².
