Principal= $38,000
rate= 8.25%
Time= 20 years
Applying the simple interest
A=P(1+rt)
substitute
A=38000(1+0.0825*20)
A=38000(1+1.65)
A=38000*(2.65)
A=$100,700
Hence in 20 years she will pay $100,700

Step-by-step explanation:
x-4y=-4
5x – 4y= 12
Answer: {x,y} = {4,2}
[1] x - 4y = -4
[2] 5x - 4y = 12// Solve equation [1] for the variable x
[1] x = 4y - 4
// Plug this in for variable x in equation [2]
[2] 5•(4y-4) - 4y = 12
[2] 16y = 32
// Solve equation [2] for the variable y
[2] 16y = 32
[2] y = 2
// By now we know this much :
x = 4y-4
y = 2
// Use the y value to solve for x
x = 4(2)-4 = 4

Philip ran out of time while taking a multiple-choice test and plans to guess on the last 444 questions. Each question has 555 possible choices, one of which is correct. Let X=X=X, equals the number of answers Philip correctly guesses in the last 444 questions. Assume that the results of his guesses are independent.
The probability that Philip answers exactly one question correctly in the last 4 questions is 0.4096.
How to calculate the probability?Probability simply means the chance that a particular thing or event will happen. It is the occurence of likely events. It is simply the area of mathematics that deals with the numerical estimates of the chance that an event will occur
It should be noted that this relates to a binomial probability. This is Illustrated as:
n! / x! (n - x)!
n = number if questions = 4
The probability will be:
P(x = 1) = (0.2)¹ × 0.8³.
= 0.4096

Answer:
8x² + 14x - 15
Step-by-step explanation:
(2x + 5)(4x - 3)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(4x - 3) + 5(4x - 3) ← distribute both parenthesis
= 8x² - 6x + 20x - 15 ← collect like terms

What is the area of this quadrilateral?
8 ft
6 ft
3.ft
A. 33 square feet
B. 42 square feet
C. 17 square feet
D. 66 square feet
Answer:
a. 33 sqft
Step-by-step explanation:
The figure is made of two non-overlapping triangles, so the total area is the sum of the areas of the two triangles
Area of a triangle is 1/2(bh) where b = base length and h = height (b and h must be perpendicular to each other)
The top triangle has b = 6 and h=8, so A=1/2(6)(8) = 1/2(48) = 24
The bottom triangle has b=6 and h=3, so A=1/2(6)(3)=1/2(18) = 9
Total area is sum of these two or 24 + 9 = 33

There are 678 more fiction books than non-fiction books. How many non-fiction books are there in the library?
Answer:
1130 non fiction
Step-by-step explanation:
F=fiction
NF=non fiction
F-678=NF
5F=8NF
so NF=5/8F
substitute:
F-678=5/8F
reduce:
3/8F=678
F=1808
NF=1130
There are 1130 non fiction books in the library.
Given that,
Ratio of fiction books (F) to non fiction books (NF) is 8:5.678 more fiction books in library.We need to find the number of non fiction books.According to the scenario, calculation of data are as follows,
[tex]\frac{F}{NF} = \frac{8}{5}[/tex]
or 5F = 8NF
Now, NF = F-678
By putting the value, we get
5F = 8 ( F - 678)
5F = 8F - 5424
3F = 5424
F = 1808
So, By putting in 1st eq. we get,
5 [tex]\times[/tex] 1808 = 8NF
NF = 9040 [tex]\div[/tex] 8
NF = 1130
Non fiction books = 1130 books.

y is directly proportional to x.
when y=30, x=6
work out an equation connecting y and x
Answer:
y = 5x
Step-by-step explanation:
Use the direct variation equation y = kx
Plug in 30 as y and 6 as x, then solve for k
y = kx
30 = k(6)
5 = k
Plug in 5 as k into y = kx
y = 5x
So, the equation relating x and y is y = 5x
Answer:
y=5x
Step-by-step explanation:
30 divide by 6 = 5 so y = 5x
