a. How many projects he wrote but did not produce
b. How many projects he produced but did not write.

Let W be the set of projects the bass guitarist wrote and P be the set of projects he produced

Step-by-step explanation:

W = Set of projects the guitarist wrote

P = Set of products he produced

A bass guitarist worked on 15 music projects last year.

Universal set = 15

He wrote and produced 5 projects.

W ∩ P = 5

He wrote a total of 9 projects.

W = 9

The Venn Diagram is given in the attached image.

a. How many projects he wrote but did not produce (W - P)?

W - P = W - W ∩ P

W - P =  9 - 5 = 4

He wrote 4 projects but did not produce them.

b. How many projects he produced but did not write (P - W)?

Universal set = (W - P) + (P - W) + W ∩ P

15 = 4 + (P - W) + 5

(P - W) = 15 - 9 = 6

He produced 6 projects but did not write them

Step-by-step explanation:

[2] 2x= 4y+14

[1] 3y+5x=9

Solve equation [2] for the variable  x

 [2]    2x = 4y + 14

 [2]    x = 2y + 7

// Plug this in for variable  x  in equation [1]

  [1]    5•(2y+7) + 3y = 9

Answer:

Charles will have $1,052 after 30 weeks

Step-by-step explanation:

Charles has $54.50 saved.

He plans to save $33.25 each week.

This means that the first week he will have $54.50 + $33.25 = $87.75

When 30 weeks have passed, he will have:

$54.50 + $33.25 * 30 = $54.50 + $997.50 = $1,052

Charles will have $1,052 after 30 weeks

A baseball diamond is a square with a side length of 90 ft. What is the distance from first base to third base in simplest radical form?

Answers

Answer:

90[tex]\sqrt{2}[/tex] ft.

Step-by-step explanation:

Using the Pythagorean theorem we get 90^2 + 90^2 = d^2 where d is the distance from 1st base to third base.  So, d^2 = 8100 + 8100 = 16200

d = [tex]\sqrt{16200}[/tex] = 90[tex]\sqrt{2}[/tex].   An easier way to do this is to recognize that the triangle formed by the diagonal of the baseball diamond and the two base paths from home to first and third is a 45-45-90 triangle.  Therefore, the hypontenuse (diagonal) equals [tex]\sqrt{2}[/tex] times a leg (90 ft.)

11. Twyla and Tony have a 30/5 balloon mortgage for $389,900 with a rate of 4.85%. How much will they pay in interest over the life of the loan? (3 points)

O $81,373.41

$92,263.82

O $107,536.50

O $121,390.73

Answers

Answer:

Explanation:

Twyla and Tony with a balloon mortgage of 30/5 will make constant payments over the space of 5 years and then complete the bulk balloon payment for 25 years remaining.

Given mortgage loan value of $389900

Interest rate of 4.85%

We are asked to calculate the interest over the life of the loan.

We will calculate interest by calculating constant payments over the period of 5 years before balloon payment is due and adding them together then subtracting the mortgage loan given $389900

Formula for constant payments :

A= P×r×r(1+r)^n/(1+r)^n-1

Where A= constant/monthly payments

r= interest rate on the mortgage loan

n= number of payments = 30×12= 360

P= mortgage loan given

A= $389900×0.0485×0.0485(1+0.0485)^360/(1+0.0485)^360-1

=$389900×0.0485×1231340.79/25388468.94

=$389900×0.0485×0.04850

A= $917.142

Payment for five years(with interest)= $917.142×60= $55028.52

Calculate balloon payment:

FV= PV(1+r)^n - P((1+r)^n-1/r)

Where FV= future value of balloon payment

PV= initial loan given

r= interest rate on loan

n= number of payments

P= monthly payments

Substitute:

FV= $389900(1+0.0485/12)^60-917.142((1+0.0485/12)^60-1/0.0485/12)

=$389900×1.2738-917.142(0.2738/0.004041)

=$389900×1.2738-917.142×67.756

= 496654.62-62141.87

FV = $434512.75

Therefore total payment made with interest over the life of the loan= balloon payment+ constant payments for five years= $434512.75+$55028.52
