Find the length of a rectangle given that the perimeter is 32 feet and the length is 1 foot more than four times the width.
Answer:
Length = 13
Step-by-step explanation:
P = 2L + 2W
L = 4W + 1
P = 32
32 = 2(4W +1) + 2W
32 = 8W + 2 + 2W
30 = 10W
W = 3
L = 4(3) + 1
L = 12 + 1
L = 13

Jaime needs to buy a new refrigerator for his apartment. He found what he needed for $1,300 at a well-known appliance store. The store is offering two options for Jaime to finance the appliance:
Option I: A store credit card with a $1,500 limit:
1) The credit card charges 16.5% annual interest rate.
2) The minimum monthly payment is $100 plus the monthly finance charge.
3) No down payment required
4) The loan is expected to be paid off in12 months to avoid additional penalties.
Option II: The appliance store offers an installment loan for his purchase:
1) Loan charges a simple interest rate of 12.5%.
2) Loan must be paid off in 12 equal payments to avoid penalties.
3) A $300 down payment is required.
Jamie should accept the second option to buy a new refrigerator for his apartment.
What is the annual interest rate?The annual interest rate on an amount borrowed or a loan is the increment added to the loan at a particular rate over the desired period of time.
The objective of this question is to weigh the two options and determine the best means by which Jamie could get a new refrigerator for his apartment.
Option 1:
The annual interest rate for the first card = $1300 × 16.5%
The annual interest rate = $214.5
The minimum monthly payment is $100 plus the monthly finance charge.The monthly finance charge on a credit card can be estimated by finding the average daily balance using the Annual interest rate and the days of the billing cycle.
The monthly finance charge [tex]\mathbf{=1300\times \dfrac{0.165}{12}}[/tex]
The monthly finance charge = $17.88
Now,
The minimum monthly payment is $100 + $17.88
The minimum monthly payment for the first month = $117.88
Provided there is no down payment;In 12 months, Jaime would have paid off the loan with an additional interest of $214.5
Total amount paid = ($117.88 × 12)+$247.5
= $1629.06
Option 2.
The appliance store offers an Installment loan;
The loan charges a simple interest rate of 12.5%;Using;
[tex]\mathbf{S.I = \dfrac{PRT}{100}}[/tex]
Since the loan must be paid in 12 equal payments, we can say the loan is paid monthly which is equivalent to 1 year.
i.e.
Time (T) = 1 year[tex]\mathbf{S.I = \dfrac{1300 \times 12.5 \times 1}{100}}[/tex]
S.I = $162.5
Given that;
The down payment = $300In the total amount of $1300, Jamie has an outstanding amount of $1000 to pay.
Thus, In 12 equal payment times,
Jamie gets to pay = $1000/12
Jamie gets to pay = $83.33 each time.
Total amount paid = $162.5 + 1300
Total amount paid = $1462.5
Therefore, we can conclude that Jamie should accept the second option to buy a new refrigerator for his apartment since the total amount paid in option 2 is lesser than that of option 1.

someone please help!! i would be so thankful! thx to who ever does (hurry please)!
15 points!!
I need 10-18 if you know any please help me out!!
Step-by-step explanation:
10.
angle QUR must be 180-41 = 139°
the reason : all angles on one side of the line QS around a single point (like U) must be 180°, as this represents a half-circle.
11.
the angle RUQ is larger.
the angle TUS is 90°.
therefore, SUN is 90° too. as well as TUQ and QUN.
the angle TUR is then TUS + 41 = 90+41 = 131°
and we know from 10. that QUR (or RUQ) is 139°.
therefore, RUQ is larger.
12.
when 2 lines cross, then the diagonally opposing angles are identical.
therefore,
84 = 4x
x = 21
13.
the same principle as in 10. applies.
all angles in one side of a line around a single point must be 180°.
so,
KMH + 84 = 180
KMH = 96°
14.
EBD = 90°
therefore, also ABE = 90°.
and we can imagine that BE extends straight to the other side of B having a point G there.
and then ABG = DBG = 90° as well.
and because these 90° angles and the principle of 12., we have
ABF = CBD = 90-62 = 28°
therefore,
CBE = CBD + DBE = 28 + 90 = 118°.
15.
ABF = 28°
as we calculated that in 14 already.
16.
due to the principles of 14 and 10 we have
CBA = 180 - CBD = 180 - 28 = 152°.
17.
this is not relevant to any of the pictures before.
angle A = angle B + 4
complementary angles are together 90°.
so,
A + B = 90
now we use the identity of the first equation in this main equation :
(B + 4) + B = 90
2B + 4 = 90
2B = 86
B = 43°
=>
A = B + 4 = 43 + 4 = 47°
18.
again, this is not related to any of the pictures before.
supplementary angles are together 180°.
D = 5E
D + E = 180
5E + E = 180
6E = 180
E = 30°
=>
D = 5E = 5×30 = 150°

t = 0.06p
================================================
Explanation:
If we plugged in p = 2, then,
t = 0.06*p = 0.06*2 = 0.12
Showing that the point (2, 0.12) is on the diagonal line of the equation t = 0.06p
This matches with what the graph shows.
The y axis is incrementing by $0.025, aka 2.5 cents, each tickmark upward. Counting up 5 tickmarks will get you to $0.125 or 12.5 cents which is fairly close to 12 cents.
When you divided the x and y values to find the constant of variation, you divided in the wrong order. You should do y/x instead of x/y.

Answer:
y = -4x + 5
Step-by-step explanation:
choose 2 easy-to-read points on the line: (0, 5) and (2, -3)
Because we have chosen the point that intersects the y-axis (0, 5) we know that the y-intercept of the line is 5.
Using equation of a line in slope-intercept form: y = mx + b (where m is the slope and b is the y-intercept):
The slope of the line = change in y ÷ change in x = (-3 - 5) ÷ (2 - 0) = -4
Therefore, y = -4x + 5

Answer:
Top left: 0.32
Top right: 0.35
Bottom left: 3.13
Bottom right: 2.86
Step-by-step explanation:
For the small box, we will divide 4.48 by 14 to get the answer for the top left box, and we will divide 14 by 4.48 to get the answer to the bottom left box.
For the large box, we will divide 9.1 by 26 to get the answer for the top left box, and we will divide 26 by 9.1 to get the answer to the bottom left box.
4.48/14 = 0.32
14/4.48 = 3.125, or as rounded to the nearest hundredth, 3.13.
9.1/26 = 0.35
26/9.1 = 2.85714285714 or as rounded to the nearest hundredth, 2.86.

Answer:
50 units
Step-by-step explanation:
The y-coordinate of both points is 30. Therefore, the line connecting the points is horizontal. To calculate the length of the line segment PQ, simply subtract the x-coordinate of point P from the x-coordinate of point Q:
30 - -20 = 3 + 20 = 50

What solution value satisfies the compound inequality x - 1 < -7 or x/4 > 1?
Answer:
x < -6 or x > 4
Step-by-step explanation:
Now, this is an OR inequality, so two separate equations are involved.
x - 1 < -7
Here, we need to add -1 to -7, which results in -6. And there's side one!
x < -6
Now for side two of this inequality.
x/4 > 1
Here, we'll multiply both sides by 4. And now, both sides are solved.
x > 4
The solution values (rather than value) that satsify the equation are x < -6 or x > 4 (so, anything between (and including) -6 and 4 will not work).

8. A study found that 72% (0.72) of people wear their seat belts? If three people
are selected at random, what is the probability that all three people wear their
seat belts?
Answer:
0.373248
Step-by-step explanation:
P(A and B) = P(A) * P(B)
Let's say one person wearing a seat belt is event A, the second person wearing a seat belt is event B, and the third person wearing their seat belt is event C
P(A and B and C) = P((A and B) and C) = (P(A) * P(B)) *P(C) = P(A) * P(B) * P(C)
The probability of each is 0.72. Our answer is therefore 0.72 * 0.72 * 0.72, or 0.72³ = 0.373248
which property justifies a+b+0=a+b
