Answer:

YOUR ANDWER MIGHT BE D

Step-by-step explanation:

The arena should be financed by selling $  320   million in bonds and borrowing $  480   million.

==========================================================

Work Shown:

Something like x = 27 means "27 million dollars of bonds were sold".

The variable x has the restriction of [tex]0 \le x \le 480[/tex] since $480 million is the ceiling for the bonds.

The variable y has the restriction of [tex]0 \le y \le 640[/tex] since $640 million is the ceiling for the money borrowed from the insurance company.

The two amounts, x and y, must add to 800 to represent the $800 million total that needs to be raised.

x+y = 800

y = 800-x

-------------------

Let's calculate the interest for each item. Use the simple interest formula.

Bonds at 7% interest rate:

i = P*r*t

i = x*0.07*1

i = 0.07x

Borrowed money at 2% interest rate:

i = P*r*t

i = y*0.02*1

i = 0.02y

Total annual interest = 0.07x+0.02y = 32

The 32 at the end represents the $32 million of interest payout. This amount of money is paid to the bondholders and to the insurance company, and is done so yearly.

-------------------

Apply substitution to solve for x.

0.07x+0.02y = 32

0.07x+0.02(800-x) = 32 ...... plug in y = 800-x

0.07x+16-0.02x = 32

0.05x+16 = 32

0.05x = 32-16

0.05x = 16

x = 16/(0.05)

x = 320

They should sell $320 million in bonds.

320 million = 320,000,000

Note how x = 320 is in the interval [tex]0 \le x \le 480[/tex]

y = 800-x

y = 800-320

y = 480

They should borrow $480 million at an interest rate of 2%

480 million = 480,000,000

Note how y = 480 is in the interval [tex]0 \le y \le 640[/tex]

Answer:

The arena should be financed by selling $320 million in bonds and borrowing $480 million.

Step-by-step explanation:

Simple interest is calculated by multiplying the principal by the interest rate (in decimal form) and the time (in years).

Let x be the amount raised by selling bonds that pay an annual simple interest rate of 7%.

Therefore:

As the total cost of the sports arena is $800 million, the amount raised from borrowing money from the insurance company at an annual simple interest rate of 2% is (800 - x).  Therefore:

To determine whether the arena can be financed so that the annual interest is $32 million, equate the sum of the two expressions for interest to 32 and solve for x:

[tex]\implies 0.07x+0.02(800-x)=32[/tex]

[tex]\implies 0.07x+16-0.02x=32[/tex]

[tex]\implies 0.05x+16=32[/tex]

[tex]\implies 0.05x=16[/tex]

[tex]\implies x=320[/tex]

As x is the amount raised by selling bonds, then the amount in bonds that should be sold is $320 million.

To calculate the amount to borrow, subtract the amount in bonds sold from $800 million:

[tex]\implies 800-320=480[/tex]

Therefore, the amount to be borrowed from an insurance company is $480 million.

As both these amounts are less than the maximum limits set, they are both valid.

The equation the line is, y = 3/8 *x - 23/8, equation of the line in POINT-SLOPE form that passes through the given points (5,-1) and (-3,-4).

A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.

Here, we have to points (5,-1) and (-3,-4)

So, by using the formula of equation of straight line of two-point form, we get,

(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )

now, solving we get,

3x-8y = 23

equation of the line in POINT-SLOPE form is,

y = 3/8 *x - 23/8

Hence, the required equation is, y = 3/8 *x - 23/8

Step-by-step explanation:

A concave polygon is a polygon that has at least one interior angle greater than 180 degrees. This means that the polygon has a "cave" or indentation on its interior. However, the fact that a polygon is concave does not automatically mean that one of its diagonals will be drawn outside the polygon. Whether a diagonal is drawn inside or outside the polygon depends on the specific arrangement of the vertices, and cannot be determined solely based on the fact that the polygon is concave.

Here,

Given that we've done it

Amount of CDs: 2100

50 faulty CDs total.

If every component of the sample is acceptable, the complete batch is accepted.

Therefore, we shall apply the "Binomial Theorem"

If there is no flaw, let p be the likelihood of success.

So, => p = 2100 - 50 / 2100

=> p = 2050/2100

=> p =0.97

q is the likelihood of a failure, or defect.

So,

=> q = 50/2100

=> q = 0.02

hence, the number of CDs chosen is 6.

Consequently, it is => P(X=6) = (0.97)6 = 0.832.

The total amount spent on tickets by Edgar is $15.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Let x be the cost of one game ticket and y be the cost of one ride ticket.

From the table, we can form two linear equations regarding the total amount spent by Erica and Penny.

10x + 5y = 10

15x + 10y = 16.25

Multiplying the first equation throughout with 2,

20x + 10y = 20

Subtracting 15x + 10y = 16.25 from the above equation,

(20x + 10y) - (15x + 10y) = 20 - 16.25

5x = 3.75

x = 0.75

Substituting x = 0.75 in 10x + 5y = 10,

7.5 + 5y = 10

5y = 2.5

y = 0.5

Cost of a game ticket is $0.75 and cost of a ride ticket is $0.50.

Total cost by Edgar = (12 × 0.75) + (12 × 0.5) = $15

The value of x is approximately 3.875.

Given that angle JKL is inscribed in a circle and the measure of angle JKL is (16x-2)°, we can use the property of inscribed angles to find x. Inscribed angles that subtend the same arc have equal measure.

Let's call the measure of angle JKL "m". Then, the measure of angle JKL = m, the measure of angle KJL = m, and the measure of angle JLK = m.

The sum of the angles in a triangle is 180°, so we have:

m + m + m = 180°

3m = 180°

m = 60°

Substituting the value of m into the equation for the measure of angle JKL:

60° = (16x - 2)°

60 = 16x - 2

62 = 16x

x = 3.875
