Answer:

Step-by-step explanation:

Let n represent nickels & d dimes

given: n + d = 25 #1 (number of coins)

given: .05n + .10d = 1.65 #2 (amount in dollars)

n = 25 - d #3 (rewrite of #1)

.05(25 -d) + .10d = 1.65 (substitute #3 in #2)

1.25 - .05d + .10d = 1.65 (multiply out the left side)

.05d = .40 (collection of like terms)

d = 8 (divided both sides by.05)

n + 8 = 25 (substitute answer for d in #1)

n = 17 (subtract both sides by 8)

There are 8 dimes and 17 nickels.

Check:

17(.05) + 8(.10) = 1.65 (answers in #2)

.85 + .80 = 1.65 (multiply out the left side)

1.65 = 1.65 ✔️ QED

Answer:  There are 8 dimes and 17 nickels.

Step-by-step explanation: 0.05N+.10D=1.65; N+D=25

Answer:

b = 2a - 1

Step-by-step explanation:

a = 1 , b = 2 x 1 - 1 = 2 - 1 = 1

a = 2 , b = 2 x 2 - 1 = 4 - 1 = 3

a = 3, b = 2 x 3 - 1 = 6 - 1 = 5

a = 4, b = 2 x 4 - 1 = 8 - 1 = 7

Answer:

b = 2a - 1

Step-by-step explanation:

We can see the pattern:

1 = 1 + 0 = 1 + 1 - 1

1 = 1 - 1

3 = 2 + 1 = 2 + 2 - 1

3 = 2 + 2 - 1

5 = 3 + 2 = 3 + 3 - 1

5 = 3 + 3 - 1

7 = 4 + 3 = 4 + 4 - 1

7 = 4 + 4 - 1

Answer:

On day 5, he should be able to do 11

Step-by-step explanation:

Day 1 - 3

Day 2 - 5 (2 more than day before)

Day 3 - 7 (2 more than day before)

Day 4 - 9 (2 more than day before)

Following this pattern of +2, day 5 should be 11.

that's my thought process, so I hope it works

the total number of out comes would be 16^2 or 256.

some extra things...

A numbered card from 1 - 10 would be 1 over 10 or 10% chance of picking correctly.

a number cube from 1 - 6 would be 1 over 6 or 16.66% chance of picking correctly.

if you want to combine these and pick one from both, it becomes 1 over 16 or 6.25% chance of picking both correctly.

Answer:

1520/4=380 per month

Step-by-step explanation:

The monthly payments for Anita and Casey are 230 and 150.

"An equation is a formula that expresses the equality of two expressions consisting of variables and/or numbers, by connecting them with the equals sign =."

Assume

Monthly payments for Anita = x

Monthly payments for Casey = y

We have

Anita pays 80 more than Casey does each month.

We can write the equation

x = y + 80

x - y = 80 ...........................(1)

Over the course of 4 months, their combined bill is 1,520.

We can write the equation

4x + 4y = 1520...................(2)

Solving equations (1) and (2) by substituting equation x = y + 80 in equation (2)

⇒4x + 4y = 1520

⇒4(y + 80) + 4y = 1520

⇒4y + 320 + 4y = 1520

⇒8y = 1520-320

⇒8y = 1200

⇒y = [tex]\frac{1200}{8}[/tex]

⇒y = 150

Substitute y = 150 in equation (1)

⇒x - y = 80

⇒x - 150 = 80

⇒x = 80+150

⇒x = 230

Hence, the monthly payments for Anita and Casey are 230 and 150.

Answer:

No need to spend more than $ 1,000

Step-by-step explanation:

assume the coach needs 10 set

10 set will cover 10×56 = 560 people that more than 453.

so,

the cost is only 10× $99 = $ 990

that less than $ 1,000

Answer:

Fewer  than 10 sets of bleachers are needed. This is because 5610  560​, which is greater than  453. The cost of 10 sets of bleachers would be ​$9910​ $ 990​, which is  less than  ​$1,000. The coach  will not  need to spend more than​ $1,000 for the bleachers.

The values of x are 7) 155°, 8) 90°, 9) 140° and 10) 20°.

Polygons are closed figures which has at least three set of line segments joined together.

The polygon with least number of sides is triangle.

7) It is a polygon with 4 sides (quadrilateral)

Sum of the interior angles of a quadrilateral = 360°

45° + 65° + 95° + x = 360°

x = 360° - (45° + 65° + 95°)

x = 155°

8) Sum of the interior angles of a polygon = (n - 2)180°, where n is the number of sides.

There are 6 sides.

Sum of the interior angles = (6 - 2)180° = 720°

x + 140 + 130 + 120 + 90 + 150 = 720

x = 90°

9) n = 5

Sum of the interior angles = (5 - 2) 180° = 540°

2x + 90 + 100 + 70 = 540

2x = 280

x = 140°

10) Sum of the exterior angles of a polygon is 360°.

4x + x + 98 + 162 = 360

5x = 100

x = 20°

Hence the values of x are found.

Answer:

Q = 9.1º

Step-by-step explanation:

Law of Cosines

c² = a² + b² - 2ab * cosC

1.3² = 7² + 7.6² - 2(7)7.6 * cosQ

1.69 = 106.76 - 106.4 * cosQ

Subtract 106.76 from both sides

-105.07 = -106.4 * cosQ

Divide both sides by -106.4

0.9875 = cosQ

Q = arccos0.9875

Answer:

bottom right

Step-by-step explanation:

Answer:

The correct solution is "4.6".

Step-by-step explanation:

Given:

Interest rate,

r = 6.2%

or,

 = 0.062

Amount,

A = 100000

Principle,

P = 76000

As we know,

⇒ [tex]A=P(1+\frac{r}{100} )^n[/tex]

On substituting the values, we get

⇒ [tex]100000=76000(1+\frac{6.2}{100} )^n[/tex]

⇒ [tex](1+0.062)^n=\frac{100}{76}[/tex]

On taking log both sides, we get

⇒ [tex]n \ log_e(1.062)=log_e(\frac{100}{76} )[/tex]

⇒                   [tex]n=\frac{ln(\frac{100}{76} )}{ln(1.062)}[/tex]

By putting the values of log, we get

⇒                      [tex]=4.5622[/tex]
