The perimeter of a rectangular playground is 86 feet, the width of the playground is 15 feet, what is the length

Answer:

$100,700

Step-by-step explanation:

Given data

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

Answer:

6 9/14

Step-by-step explanation:

Well, we know that 9/14 is bigger than 1/2, so that means that 6 9/14 will be rounded to 7. If it is over 1/2, you round up, if 1/2 less, than it stays the same.

Answer:

Step-by-step explanation:

9/10 is equal to 18/20

3/4 is equal to 15/20

3/5 is equal to 12/20

9/20 is equal to 9/20

The next answer is 6/20 which is equivalent to 3/10

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

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,

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.

The probability that Philip answers exactly one question correctly in the last 4 questions is 0.4096.

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.

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

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

Answer: x=4 y=2

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
