Answer:

  12. $1,035,057.23

  13. $988,881.23

  14. $7,762.93

  15. $8,686.16

  16. $967,647.66

Step-by-step explanation:

The annuity and amortization formulas are used for problems like this.

  sum of monthly payments = P((1 +r/12)^(12t) -1)/(r/12)

  monthly amount available = P(r/12)/(1 -(1 +r/12)^(-12t))

__

12. The sum of monthly payments of 74, accumulated at 9% compounded monthly for 52 years is ...

  A = ($74)((1 +.09/12)^(12·52) -1)/(.09/12) = $1,035,057.23

__

13. The total of payments is ...

  $74×12×52 = $46,176

So, the interest earned is ...

  $1,035,057.23 -46,176 = $988,881.23

__

14. The amount available in perpetuity is the monthly interest on this account balance.

  $1,035,057.23 × .09/12 = $7,762.93

__

15. The monthly amount available for 25 years is found from the amortization formula:

  A = $1,035,057.23(.09/12)/(1 -(1 +.09/12)^(-12·25)) = $8686.16

__

16. The amortization formula is used for this, too.

  8066 = P(.094/12)/(1 -(1 +.094/12)^(-12·30)) = 0.00833568P

  P = $8066/0.00833568 = $967,647.66

Quick Copy: 5 + 0.06x

Copy Place: 10 + 0.04x

5 + 0.06x = 10 + 0.04x

0.02x = 5

x = 5/0.02

x = 250

Answer: 250 pages

Check

Quick Copy: 5 + 0.06(250) = 5 + 15 = 20

Copy Place: 10 + 0.04(250) = 10 + 10 = 20

For 250 copies, both places cost $20. 250 copies is the correct answer.

If ABC is reflected across the y-axis, what are the coordinates of C?

Answers

Answer:

C

Step-by-step explanation:

The y axis is vertical so you only change the x value.

The coordinate of C after being reflected across the y-axis is (-6, 3) option (C) (-6, 3) is correct.

What is geometric transformation?

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

We have a triangle shown on the coordinate plane.

If ABC is reflected across the y-axis,

Then the coordinate of C

From the figure, the coordinate of C is(before reflection)

C = (6, 3)

The rule for transformation if reflected across the y-axis:

(x, y) → (-x, y)

(6, 3) → (-6, 3)

Thus, the coordinate of C after being reflected across the y-axis is (-6, 3) option (C) (-6, 3) is correct.

In a class of 40 students, 75% returned their permission slips for the school field trip. HowIn a class of 40 students, 75% returned their permission slips for the school field trip. How many students returned their permission slips

Answers

Answer:

30 students

Step-by-step explanation:

Given

[tex]Students = 40[/tex]

[tex]\% = 75\%[/tex] ---- percentage of those that returned their slips

Required

Determine the number of those that returned their slips

Represent the number with n

To calculate n, we simply multiply the number of students by the percentage of those that returned their slips

i.e.

[tex]n = 40 * 75\%[/tex]

Convert % to decimal

[tex]n = 40 * 0.75[/tex]

[tex]n = 30[/tex]

Hence, 30 students returned their slips

Step-by-step explanation:

(2). f( - 4) = 4( - 4 ) + 2 = - 14

g( - 4) = (5/2)(- 4) - 4 = = - 14

f( - 4) = g( - 4) (True)

(3). f(6) = 4(6) + 2 = 26

g(12) = (5/2)(12) - 4 = 26

f(6) = g(12) (True)

(4). g(2) = (5/2)(2) - 4 = 1

f(2) = 4(2) + 2 = 10

Alfonso made a scale drawing of a tower. The actaul height of a tower is 25 feet. The scale Alfonso used in his drawing is 1 in.:10 ft. What is the height of the tower in Alfonso's drawing?

Answers

Answer:

2.5 inches

Step-by-step explanation:

Using Alfonso's scale of the drawing, which is 1in=10 ft, we can conclude the height of the tower to be 2.5 inches because

the actual height of the tower is 25 feet

10+10=20, which by following the scale, is 2 inches

we then have 5 left, 5 being half of 10, and .5 being half an inch.

Therefore the height of the tower using Alfonso's scale is 2.5 inches.

A local grocery store received a new shipment of apples. The apples arrived in 8 crates with 20 apples in each crate. If the store pays $0.21 per apple and sells each apple for $0.79, what would the profit be after selling all of the apples?
A.
$16.24
B.
$22.12
C.
$92.80
D.
$126.40

Answers

The correct answer is C. $92.80

Explanation:

The first step is to calculate the profit for each apple, this can be found by subtracting the cost the store pays from the selling price.

$0.79 - $0.21 = $0.58

This means for each apple the store sold, the profit (amount of money earned) is $0.58. Now, let's find the total apples the store received, and therefore the total of apples the store can sell.

8 creates each with 20 apples

8 x 20 = 160 apples

Finally, multiply the profit for selling one unit by the total apples

160 x 0.58 = $92.8

1+n/7=3

A. Do the reciprocal of 1/7
B. Divide both sides by 7
C. Multiply both sides by 7 for the inverse
D. Subtract 1 on both sides for the inverse

Answers

Answer:

C.

Step-by-step explanation:

I'm assuming that the equation is (1+n) / 7 = 3, where 1+n is the numerator and 7 is the denominator.

In this case, to isolate for n, you have to multiply both sides by 7.

then you get 1+n = 3/7, and then you can get n = 3/7 - 1

Answers

Leak rate is affected by the pressure difference (inlet vs outlet), the type of gas that is leaking and the flow characteristics of the leak path. In terms of units, a leak rate can be defined in different ways, but if the SI units are used, then this is expressed in mbar·litre/second.
