Answer:
The answer is 1.2
Step-by-step explanation:
It takes Rita 22.75 on average, and it take Erika 21.55 to walk the mile on average.
21.55 + 1.2 = 22.75
therefore, it takes Erika 1.2 minutes per mile less than Rita.
On average, Erika is much slower than Rita by 1 minute.
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Since, There are two sets of data: Erika's and Rita's.
Now, we have to find the average values for each of both and compare them.
We would assume that the order of the presentation of data points is alternating,
first for Erika followed by Rita.
Hence, To illustrate what I mean, let's say
in Day 1, Erika's time is 20 and Rita's time is 21.25.
In Day 2, Erika's time is 21.5 and Rita's is 24.75.
And so on and so forth.
So, We get;
Erika's average is,
= (20+21.5+22.75+23.25+20.25)/5
= 21.55
Rita's average is,
= (21.25+24.75+23+23+20.75)/5
= 22.55
Hence, On average, Erika is much slower than Rita by 1 minute.

A) a n = 8n − 15
B) a n = −8n − 15
C) a n = 8n − 23
D) a n = −8n − 23
Answer:
C
Step-by-step explanation:
A) a(n) = 8n - 15
this is incorrect because if n = 3, then a = 9 not 1.
B) a(n) = -8n-15
this is incorrect because if n = 3, then a = -39 not 1.
C) a(n) = 8n-23
this is correct because if n = 3, then a = 1, and if n = 9, then a = 49.

A bigger down payment means that the borrower has more money, and can afford a bigger loan. D. A bigger down payment is money paid toward principal, interest free, which also decreases the amount paid monthly.
The correct option is D, A bigger down payment is money paid toward principal, interest-free, which also decreases the amount paid monthly.
What is interest?The amount of money a lender or financial organization earns for lending out money is known as interest.
We know that monthly payments include the interest on the principal amount that is not been paid during the purchase of an item, if the down payment is more than the principal amount that the customer does not pay will decrease which will decrease the loan amount, thus, the interest on the principal amount will decrease as well.
Now, as the interest and the principal amount have both is been reduced, therefore, the monthly instalment(monthly payment) will be reduced as well.
Hence, the correct option is D, A bigger down payment is money paid toward principal, interest-free, which also decreases the amount paid monthly.

Three students each have 10.2 pounds of laundry to wash. A fourth student has 3.4 pounds
of laundry to wash. How many pounds of laundry do they have in total? (give steps please!)
Answer:
34 pounds
Step-by-step explanation:
hi again!
so if three students have 10.2 to wash, we can find how many pounds the 3 students have in total by multiplying 10.2*3, because that is the same as doing 10.2+10.2+10.2. this gives us a result of 30.6 points for the three students.
now if the fourth student has 3.4 pounds, we just add that to 30.6
thus we have 30.6+3.4 which equals your answer, 34.

Rita borrowed $7500 at an interest rate of 3%. The interest paid is $1462.50. For how many years did she borrow the money?
Answer: 6.5 years
Step-by-step explanation:
the formula for simple interest is:
SI = PRT, SI is the interest after a time, P is the principle amount, R is the rate, and T is the time passed
In our case:
1462.50 = 7500 x 0.03 x T
Solving for T:
1462.50 = 225T
.: T = 1462.50/225 = 6.5 years
She borrowed the money for 6.5 years

∠A = 70°
∠C = 110°
∠ B = 115°
∠D = 55°

∠B = 100°
∠D = 80°
∠E = 141°
∠C = 39°

∠V = 101°
∠T = 79°
∠U = 86°
∠W = 94°
Cyclic Quadrilateral
A cyclic quadrilateral has all it vertices on the circumferences of the circle . opposite angle of a cyclic quadrilateral add up to 180 degrees. The sum of the whole angles add up to 360 degrees. Therefore, tha angle measure of each inscribed quadrilateral is as follows
10.
5x + 20 + 7x - 8 = 180
12x + 12 = 180
12x = 180 - 12
12x = 168
x = 168 / 12
x = 14
Therefore,
∠P = 5x + 20 = 5(14) + 20 = 90°∠R = 90°∠Q = 10x = 10(14) = 140°∠S = 40°11.
4z - 10 + 10 + 5z = 180
9z = 180
z = 20
Therefore,
∠A = 4z - 10 = 4(20) - 10 = 70°∠C = 110°∠ B = 6z - 5 = 6(20) - 5 = 115°∠D = 55°12.
1 / 2 z + 1 / 4 z + 30 = 180
3 / 4 z + 30 = 180
3 / 4 z = 150
3z = 600
z = 600 / 3
z = 200
Therefore,
∠B = z / 2 = 200 / 2 = 100°∠D = z / 4 + 30 = 200 / 4 + 30 = 80°∠E = z - 59 = 200 - 59 = 141°∠C = 39°13.

C. Both the first and second players get blue characters. What is the
probability that the third player does not get a blue character?
Answer: B: 4/13, C: 3/4
B:
There were originally a total of 14 characters (including 5 blue characters) from the collection. Since the first player got a blue character, there are now 13 characters to choose from and 4 of them are blue. Therefore, the probability is 4/13.
C: If both the first and second players get blue characters, then there will be 12 characters left, and 3 of them are blue. Now we know that there are 9 characters that are NOT blue. Therefore, the probability is 9/12, or 3/4.
Roderigo has just finished paying back his $8,575 unsubsidized Stafford loan, which he took out to fund his four-year degree. The loan had a duration of ten years and an interest rate of 7. 1%, compounded monthly. Roderigo will allow interest capitalization. If Roderigo made monthly payments to pay off his loan, how much interest did he pay in total? Round all dollar values to the nearest cent. A. $4,547. 02 b. $3,426. 20 c. $7,353. 80 d. $5,436. 20 Please select the best answer from the choices provided A B C D.
Roderigo will pay $7353.80 in interest.
Interest capitalization means the interest earned is added to the principle amount so first we will use compound interest formula.
What is the formula for compound interest?[tex]Amount=p(1+\frac{r}{n} )^{nt}[/tex]
p = 8575
r = 7.1% or 0.071
n = 12
t = 4
Putting the values in formula we get
[tex]Amount=8575(1+\frac{0.071}{12} )^{12(4)}[/tex]
[tex]Amount=8575(1+\frac{0.071}{12} )^{48}[/tex]
Solving this we get;
Amount = $11381.94
For the next part we have EMI formula as,
[tex]EMI=\frac{pr(1+r)^{n} }{(1+r)^{n-1}}[/tex]
p = 11381.94
[tex]r=\frac{7.1}{\frac{12}{100} }=0.005917[/tex]
[tex]n=(12)(10)\\n=120[/tex]
[tex]EMI=\frac{11381.94(0.005979)(1+0.005979)^{120} }{(1+0.005979)^{120}-1}[/tex]
EMI = $132.74
Now total payments made in 120 months (10 years) =
[tex]132.74(120)=15928.80[/tex] dollars
interest paid =
[tex]15928.80-8575=7353.80[/tex] dollars
Hence, Roderigo will pay $7353.80

Answer:
y ≥ -6
Step-by-step explanation:
Hello!
The domain is the interval in which the graph is located vertically on the coordinate plane.
The range is the interval in which the graph is located horizontally on the graph.
Since we are finding the range of the graph, we draw a horizontal line at the lowest point of that graph. We can see that the line is y=-6 because the lowest point given by that horizontal line is -6.
Now that we know that it is the lowest point, we must find the highest point of the graph. Looking at it, we can see that it goes infinitely up, or it continues above -6. This means that the graph hits every horizontal line above -6, or all the values above -6.
The interval would be -6 ≤ y ≤ ∞ (greater than or equal to sign because the graph includes the point) or we can simply rewrite it as all values above -6 or y ≥ -6.
