The total money you have is $40.14.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

There are 7 times as many nickels as pennies

Let there are n nickles and p pennies.

⇒ p = 7n

Now, there are  16 nickels and pennies altogether

⇒ p + n = 16

Put p = 7n we get,

⇒ 7n + n = 16

⇒ 8n = 16

⇒ n = 16/8

⇒ n = 2

Therefore,  p = 7*2

⇒ p = 14

Thus there 14 pennies and 2 nickels.

Now, since 1 penny = 0.01 dollars

and 1 nickel = 20 dollars

⇒ 14 pennies = 14*0.01 dollars = 0.14 dollar

and, 2 nickel = 2*20 dollars = 40 dollars

So, Total money = $40 + $0.14

⇒ Total money = $40.14

Thus, the total money you have is $40.14.

Answer:

a:tan0= 12/5

c: sin0=12/13

Step-by-step explanation:

cosec t(heta) = 13/12

1/sin t = 13/12

sin t = 12/13

cos t = √ (1 - (12/13)² ) = √ ( 1 - 144/169 ) = √25/169

cos t = 5/13

tan t = sin t/ cos t = (12/13) / (5/13) = 12/5

sec t = 1 / cos t = 13/5

Answer: A ) and C )  are correct:

tan theta = 12/5 and sin theta = 12/13

The change in the value of x, as a percentage, is given by:

[tex]\frac{b - a}{a} \times 100\%[/tex]

The percentage change is given by the change multiplied by 100% and divided by the initial value.

In this question, x varies from [tex]x = a[/tex] to [tex]x = b[/tex], which means that the initial value is a, and the change is b - a. Then, the percentage chance in the value of x is given by:

Answer:

Solution: (3,5)

Step-by-step explanation:

y = x + 2 and

y = - x + 8

y = y

x + 2 = -x + 8

x + x = 8 - 2

2x = 6

x = 6/2

x = 3

Substitute x for 3 in one of the equations to find y.

y = 3 + 2

y = 5

Answer:

  0.927184

Step-by-step explanation:

Assuming you want cos(338°), it is equal to cos(22°). This value is an irrational root of a 26th-degree polynomial. (Neither the polynomial, nor the root are easy to find by hand.)

The values of trig functions for 30° and 45° are well-known, as are half-angle and angle sum/difference formulas. The nearest angle for which cosine is relatively easy to find is 22.5°. A 2nd-order Maclaurin series expansion of the cosine function about that angle gives the approximation ...

  cos(x) ≈ cos(π/8)(1 -π²/128) +π/8·sin(π/8) +(π/8·cos(π/8) -sin(π/8))x -1/2·cos(π/8)x²

For your angle of 22°, the value of x needed in this expression is 11π/90. The values of cos(π/8) and sin(π/8) are the irrational numbers ...

  cos(π/8) = √(2 +√2)/2 ≈ 0.92387953

  sin(π/8) = √(2 -√2)/2 ≈ 0.38268343

If you use the approximation pi ≈ 355/113, both for the above formula and for the angle of interest, this reduces to the sum ...

  cos(22°) ≈ 71√(2-√2)/16272 +132383951√(2+√2)/264777984

This would be tedious to calculate by hand, but is not impossible. The value this sum produces will be correct when rounded to 7 decimal digits.

Before calculators, trig function values were found in published tables. These days, tables are available on-line. Previously, they were published in books, usually along with information that helped with interpolation between table values, when necessary. The attachment shows a portion of an online cosine table suitable for answering your question.

Before calculators, mathematicians spent lifetimes calculating accurate trig tables. For all but a very few angles, the cosine function of rational degree values will be an irrational number, as it is for cos(22°).

The scalar triple product is 0.

If v = 4i - j and w = 6i + 7j - 4k, then their cross product is

v × w = (4i - j) × (6i + 7j - 4k)

v × w = 24 (i × i) + 28 (i × j) - 16 (i × k) - 6 (j × i) - 7 (j × j) + 4 (j × k)

v × w = 28k - 16 (-j) - 6 (-k) + 4i

v × w = 4i + 16j + 34k

and

u • (v × w) = (i + 4j - 2k) • (4i + 16j + 34k)

u • (v × w) = 4 + 64 - 68

u • (v × w) = 0

Yes, they are coplanar.

The vectors v and w together span a plane. v × w is a vector that is perpendicular to this plane. Since the dot product of u with this vector is 0, this means u is perpendicular to v × w, which in turn means that u is in the same plane as v and w.

Answer:

$26.91

Step-by-step explanation:

Multiply $2.99 with 9.

Reason is that its $2.99 a gallon for gas and you need 9 gallons to fill up your vehicle

That equals $26.91.

Answer:

$26.91

Step-by-step explanation:

Since 1 gallon costs $2.99, multiply 2.99 by 9.

2.99 x 9

= $26.91

It will cost you $26.91 to fill up your tank that holds 9 gallons.

Answer:

56

Step-by-step explanation:

1. We can use the exterior angle theorem to find the value of y. The exterior angle theorem states that the exterior angle of a triangle is equal to the sum of the two remote sides. This means that (y - 25) + (y + 12) = y + 43

2. (Solving)

Step 1: Simplify both sides of the equation.

Step 2: Subtract 2y from both sides.

Step 3: Subtract 43 from both sides.

Step 4: Divide both sides by -1.

Step 5: Check if solution is correct.

Therefore, y = 56.
