[tex] \sin(90 - x) = \cos(x) [/tex]

[tex] \sin(90 - (3x + 3) = \cos(x + 71) [/tex]

[tex]90 - 3x - 3 = x + 71[/tex]

What is the value of x?
to
x = [?]°
o

Answers

Answer:

The value of x from the figure is 58 degrees

To get the value of x, we will use the formula:

The angle at the vertex = 1/2(difference of angles at the arc)

Angle at the vertex = 1/2(160 - x)

51 = 1/2(160 - x)

102 = 160 - x

x = 160 - 102

x = 58 degrees

Hence the value of x from the figure is 58 degrees

A bus company is replacing all the old seats in its buses with new ones. The company owns 12 buses and each bus has 21 seats. It costs $93.50 to
purchase each new seat, as well as an additional $31.20 to install each new seat. What is the total cost the company will pay?

Answers

Answer:

54,992.70$

Step-by-step explanation:

93.50 x 21 = 1963.5

31.20 x 21 = 655.2

1963.5 + 655.2 = 2618.7

2618.7 x 12 = 54,992.70$

Suppose that 21 inches of wire costs 63 cents.
At the same rate, how much (in cents) will 54 inches of wire cost?

Answers

Answer:

162 cents

Step-by-step explanation:

to find the rate you want take the inches which is 21 and divide by the cost which is 63 and find the rate is 3 which means each inch costs 3 cents and so with that rate you can find the cost of 54 inchest of wire so you take your 54 inches and multiply it by 3 which is the cents per inch and find that 54 inches of wire would cost you 162 cents

Which of the following is a factor of the expression 24x^2-30x-9?
Group of answer choices

12x+1

4x-3

2x+3

4x+1

Answers

Answer:

4x + 1

Step-by-step explanation:

24x² - 30x - 9 ( factor out 3 from each term )

= 3(8x² - 10x - 3) ← factor the quadratic

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 8 × - 3 = - 24 and sum = - 10

the factors are + 2 and - 12

use these factors to split the x- term

8x² + 2x - 12x - 3 ( factor the first/second and third/fourth terms )

= 2x(4x + 1) - 3(4x + 1) ← factor out (4x + 1) from each term

= (4x + 1)(2x - 3)

then

24x² - 30x - 9 = 3(4x + 1)(2x - 3) ← in factored form

so (4x + 1) is a factor of the expression

A right triangle has one leg that is 7 centimeters. The hypotenuse is 25 centimeters. Find the length of the other leg.

Answers

Since this is a right triangle, we can use the Pythagorean Theorem to help us.

 [tex](length-of-leg1)^2+(length-of-leg2)^2 = (length-of-hypotenuse)^2\\[/tex]

Known information:

one leg's length: 7 cmhypotenuse's length: 25cm

Now let's plug the known information into the equation:

 [tex]7^2 + (length-of-leg2)^2=25^2\\(length-of-leg2)^2 = 25^2-7^2\\\\(length-of-leg2)^2 = 576\\\\length-of-leg2=24[/tex]

Thus the length of the other leg is 24cm.

What is the sum of 10 of the interior angles of a regular dodecagon?

Answers

Answer: 1500

Step-by-step explanation:

180° x (12-2) = 180° x 10

(got 12 because a regular dodecagon has 12 congruent sides.)

1800°/ 12 =150

150° x 10= 1500°

Martin has a combination of 33 quarters and dimes worth a total of $6. which system of linear equations can be used to find the number of quarters, q, and the number of dimes, d, martin has? q d = 6 25q 10d = 33 q d = 6 0.25q 0.1d = 33 q d = 33 25q 10d = 6 q d = 33 0.25q 0.1d = 6

Answers

The linear equations which can be used to find the number of quarters, q, and the number of dimes, d will be  [tex]q+d=33[/tex]    &     [tex]0.25q+0.1d=6[/tex]

What will be the Linear equation for the given data?

It is given that

Martin has a combination of 33 quarters and dimes worth a total of $6.

Here

q = number of quarters

d = number of dimes

The linear equation can be represented as

[tex]0.1\ dollars =1 \ dime[/tex]

[tex]0.25\ dollars = \ 1 \ quarters[/tex]

now the equation will be

[tex]0.25q+0.1d=6[/tex]

The quarters and dimes in total 33. Therefore,

[tex]q+d=33[/tex]

Therefore, the combined equation will be as follows:

[tex]q+d=33[/tex]

[tex]0.25q+0.1d=6[/tex]

Thus linear equations  will be [tex]q+d=33[/tex]   &     [tex]0.25q+0.1d=6[/tex]

The volume of this right circular cylinder is 64π cubic yards. If h, the height of the cylinder, is 4 yards, what is r, the radius of the base?

Answers

Answer:

h = 4 cm

Step-by-step explanation:

The formula for volume of a cylinder is

V = πr²h      where V is the volume, r is the radius, and h is the height.

We are given V = 64π, and r = 4, plug those in and solve for h

64π = π(4²)h

64π = 16πh

(64π)/(16π) = (16πh)/(16π)      (divide both sides by 16π)

4 = (16π)/(16π)h

 4 = h

Answer:

Radius = 4 yards

Solution:

Here, we are provided a right circular cylinder with :

Volume = 64 π cubic yards Height = 4 yards Radius = ?

We know that :

[tex] \quad\hookrightarrow\quad{\pmb{ \mathfrak { Volume = \pi r^2 h }}}[/tex]

Therefore,

[tex] \implies\quad \sf{V = \pi r^2 h }[/tex]

[tex] \implies\quad \sf{64\pi = \pi r^2 \times 4 }[/tex]

[tex] \implies\quad \sf{ \pi r^2 \times 4 = 64\pi}[/tex]

[tex] \implies\quad \sf{r^2 =\dfrac{64\pi}{\pi \times 4} }[/tex]

[tex] \implies\quad \sf{ r^2 =\dfrac{\cancel{64}}{\cancel{4}}\times \cancel{\dfrac{\pi}{\pi}}}[/tex]

[tex] \implies\quad \sf{ r^2 = 16}[/tex]

Answers

Answer:

Step-by-step explanation    

:[tex]\sqrt{x}[/tex] 300 with 12 and you simply get 25

The function that represents the balance after t years is FV = $300( 4)^4t. The balance of the account after four years is; $914.92.

What is the function that represents the balance after t years?

The formula for calculating future value:

FV = P (1 + r)^nm

Where: FV = Future value

P = Present value

R = interest rate = 12%/4 = 3%

m = number of compounding = 4

N = number of years

Thus FV = $300( 1+ 3)^4t

FV = $300( 4)^4t

Then the account balance after 4 years;

$300( 4)^(4 x 4)

= $914.92
