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

Q = 9.068721546032704

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

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:

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:

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:

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]

Option D is correct

$972.84 is invested in total after 1 year.

Correct option is (D)

Compound interest is generally understood to be interest that is earned on both the original investment and any subsequent interest. Compound interest is, thus, the interest earned on both the initial principal and the interest that has already been accrued on this principal.

As per the given data:

Compounding frequency (n) = 12

Final value (FV) = $1000

Time period (t) = 12 months = 1 year

[tex]FV = P(1+\frac{r}{n})^{nt}[/tex]

FV – Future worth of the investment is the final balance in our calculation.

P – Initial balance (the value of the investment);

r – Annual interest rate (in decimal);

n – Number of times the interest is compounded per year (compounding frequency); and

t – Numbers of years the money is invested for.

Substituting the given values

[tex]1000 = P(1+\frac{0.06}{12})^{12 \times 1}[/tex]

[tex]P = \$ 972.84[/tex]

Hence, $972.84 is invested in total after 1 year.
