Answer:

<h2>D. x ≈ 31.3°</h2>

Step-by-step explanation:

The triangle CBV is angled triangle with right angle at ∠VBC.

Since  ∠VBC = (3x-4) °

To get the value of x, we will equate the angle  ∠VBC to 90°

This results into (3x-4) ° = 90

Simplifying the resulting equation;

3x-4 = 90

Adding 4 to both sides;

3x-4+4 = 90+4

3x = 94

Dividing both sides by 3

3x/3 = 94/3

x = 31.33°

x ≈ 31.3°

Sandra wants to buy a new mp3 player that is on sale for $95 she has saved $73 how much more money does she need
Schach [20]

Answer:

For Sandra to save up and purchase the mp3 she must save additional $22.

Step-by-step explanation:

This problem requires us to understand the concerns of deficit/balance

Step one

We were told that mp3 cost $95

And Sandra has saved $73

Hence for her to purchase the mp3 she has to save up to $95 which is the benchmark price for the item

Step two :

Hence the amount of money to balance up is

=Cost of mp3- Sandra's savings

= $95-$73

=$22

6 square units.
1 sq units would be 1 mile, so 4 units are 4 miles. A little bit more than 4 is 6.

Simplifying Complex fractions using any method
zloy xaker [14]

Answer:

3ab

-------------------

(b+a)

Step-by-step explanation:

3/a - 3/b

-------------------

1/a^2 - 1/b^2

Multiply the top and bottom by a^2 b^2/ a^2/b^2 to clear the fractions

(3/a - 3/b) a^2 b^2

-------------------

(1/a^2 - 1/b^2) a^2b^2

3ab^2 - 3 a^2 b

-------------------

b^2 -  a^2

Factor out 3ab on the top

3ab( b-a)

-------------------

b^2 -  a^2

The bottom is the difference of squares

3ab( b-a)

-------------------

(b-a) (b+a)

Cancel like terms from the top and bottom

3ab

-------------------

(b+a)

Choose the explicit and recursive formulas for the geometric sequence 45, 135, 405, 1215, 3645, .... PLEASE HELP ASAP
sesenic [268]

Answer:

Option (B)

Step-by-step explanation:

Given sequence is 45, 135, 405, 1215, 3645..........

Since it's a geometric sequence,

Common ratio of each successive term to the previous term

r = \frac{135}{45}=3

First term of the sequence 'a' = 45

Explicit formula of a geometric sequence will be,

a_n=a(r)^{n-1}

a_n=45(3)^{n-1}

Recursive formula of this sequence will be,

a_n=3(a_{n-1}), a_1=45

Therefore, Option (B) will be the answer.
