Answer:

$471.60

Step-by-step explanation:

The double time rate is not specified in the question. But I will assume it's 2 times the normal rate. Therefore...

13.10 x 20 + 8 x (13.10 x 2)

Answer = $471.60

Answer:

7 x 9 = 63 7 is a FACTOR of 63

9 is a FACTOR of 63

7 and 9 are even DIVISORS of 63

63 is a MULTIPLE of 7 and 9

63 is a PRODUCT of 7 and 9

63 is evenly DIVISIBLE by 7 or 9

Writing 63 as a product of as many factors will be: 7 × 9, 3 × 21, 9 × 7 and 21 × 3.

The factors of 63 include 1, 3, 7,9, 21 and 63.

Since we've been given the information that we should not use 1 as a factor when multiplying according to the question, then the 63 as a product of its factors will be:

3 × 21 = 63

7 × 9 = 63

9 × 7 = 63

21 × 3 = 63

Answer:

  √35 +3√7 -6 . . . square units

Step-by-step explanation:

The area can be figured a number of ways. The figure can be divided into parts, and the areas of those parts added.

Or, the area of the enclosing rectangle can be found, and the rectangle at upper right that is not shaded can be subtracted from that. We choose the latter.

The overall width is the sum of the given partial widths:

  width = (√7 -2) + (2) = √7

Then the area of the bounding rectangle is ...

  A = LW = (√5 +3)(√7) = √35 +3√7

The area of the upper right empty-space is ...

  A = LW = (3)(2) = 6

Then The area of the shaded figure is ...

  √35 +3√7 -6

Answer:

11th term is -45x+56

Answer:

a_11 = -45x + 56

Step-by-step explanation:

An arithmetic sequence has a constant difference which can be found by subtracting a term from the next term.

constant difference = d = -9x + 11 - (-5x + 6)

d = -9x + 11 + 5x - 6

d = -4x + 5

The nth term of an arithmetic sequence is

a_n = a_1 + (n - 1)d

a_11 = a_1 + (11 - 1)(-4x + 5)

a_11 = -5x + 6 + 10(-4x + 5)

a_11 = -5x + 6 - 40x + 50

a_11 = -45x + 56

Hello ;)

We have :

Claude's net pay → $985.50

Claude's gross pay → $1350.00

We know that the gross pay represents 100 % of the salary.

So :

$1350.00 ⇔ 100 %

$985.50 ⇔ ? %

? = 985.5 × 100 ÷ 1350 = 73 %

Claude's net pay is 73 % of the gross pay.

:-)

Based on his net pay being $985.50 and his gross pay being $1,350.00, the net pay is 73% of the gross pay.

To find out how much of the percentage of something a variable is, you make the variable the numerator and the other measure the denominator.

In this instance that would be:

= Net pay / Gross pay x 100%

= 985.50 / 1,350 x 100%

= 73%

In conclusion, the net pay is 73% of the gross pay.

Answer:

24 is the answer. Hope it helps you! Stay blessed.

Recall that

• tan(x) = sin(x) / cos(x)

• sin(x) sin(y) = - 1/2 (cos(x + y) - cos(x - y))

• cos(x) cos(y) = 1/2 (cos(x + y) + cos(x - y))

Then we can write

tan(6x) tan(7x) = (sin(6x) sin(7x)) / (cos(6x) cos(7x))

tan(6x) tan(7x) = - (cos(13x) - cos(x)) / (cos(13x) + cos(x))

Make this replacement in the original equation and simplify:

tan(6x) tan(7x) = -1

- (cos(13x) - cos(x)) / (cos(13x) + cos(x)) = -1

(cos(13x) - cos(x)) / (cos(13x) + cos(x)) = 1

cos(13x) - cos(x) = cos(13x) + cos(x)

2 cos(x) = 0

cos(x) = 0

Solving for x gives

x = π/2 + nπ = (2n + 1)π/2

where n is any integer. However, since 2n + 1 is odd, for any odd multiple of π/2, we would end up with

tan(6 (2n + 1)π/2) = tan((2n + 1)×3π) = tan(odd multple of π/2)

since odd×odd = odd, and cos(odd multiplie of π/2) = 0, which would make tan(6x) undefined.

Therefore there are no solutions to this equation.
