The angle formed between the ground and the bat is 62.04 degrees

From the given question, we have the following parameters:

Length of the bat = 32in

Measure of the distance from the bat to the ladder = 15in

angle of elevation

Using the SOH CAH TOA identity

Cos θ = adjacent/hypotenuse

Cos θ = 15/32

θ = arccos(15/32)

θ = 62.04degrees

Hence the angle formed between the ground and the bat is 62.04 degrees

By decomposing the figure in simpler ones, we conclude that its area is 9 square units.

Let's read the figure from the top.

First, we can see in the top two triangles that have an area of half a square unit, then adding these two we have one square unit.

Below that, there are 4 square units inside the figure.

On the left and right sides, there are triangles of base of 1 unit and height of 2 units, then each of these triangles has an area of:

a = 1*2/2 = 1 square unit

And we have 2 of these triangles, so the total area is 2 square units.

Finally, on the bottom we can see 4 triangles like in the top part, we know that each one of these measure 0.5 square units, then the 4 add up to 2 square units.

Adding all the areas above, we see that the total area is:

A = (1 + 4 + 2 + 2) square units = 9 square units.

So the correct option is C

Answer:

Option A) D: {0 ≤ x ≤ 12}; The domain represents the amount of gas used

Step-by-step explanation:

Let

x ----> number of gallons used (independent variable)

y ---> number of miles remaining (dependent variable)

we know that

The domain of a function is the set of all possible values of x

so

The domain represents the amount of gas used

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Given

[tex]\frac{2A}{3}[/tex] = 8 + 4A

Multiply through by 3 to clear the fraction

2A = 24 + 12A ( subtract 12A from both sides )

- 10A = 24 ( divide both sides by - 10 )

A = - 2.4 → A

Answer:

5y

Step-by-step explanation:

All you have to do is subtract 1 from both side so subtract 1 from one side than the other. If you have to find out what y equals, then after subtracting, divide 5 from both sides and y would equal 5. Hope this helped

Answer:

1)  If you want to solve the equation, x is 0/5 or 0

2) If you want to subtract 1, the answer is 5y = 0

Step-by-step explanation:

1)  5y + 1 = 1

        5y = 0

2) 5y + 1 = 1      Subtract both sides by 1

         5y = 0     Isolate the variable by dividing 5 on both sides

            y = 0/5 or 0

Answer:

Step-by-step explanation:

The car dealership sold 24 basic model cars and 16 fully-loaded model cars. This was determined by creating and solving a set of linear equations based on the given information.

This question can be approached using the method of linear equations. We know that the total number of cars sold is 40 and the total sales is $880,000. We can represent the number of basic model cars as 'b' and the fully-loaded model cars as 'f'. The cost of a basic model car is $20,000 and for a fully-loaded model, it is $25,000. Therefore, we can establish two equations:

The system of these linear equations could be solved either by Substitution or Elimination method. Through careful calculation, it can be found that the answer is b=24 (basic models) and f=16 (fully-loaded models).

So, the correct answer is Option B : The dealership sold 16 fully loaded models and 24 basic models.

Answer:

Step-by-step explanation:

72-32=40

Answer: 47.5 ft^2

Step-by-step explanation: First find the area of the rectangle using the formula length*height. This is 10*4 or 40.

Then find the area of the bottom triangle using the formula (base*height)/2. This will be (3*3)/2, which simplifies to 9/2, which is 4.5.

Then find the area of the top triangle using the same formula, which will be (2*3)/2, which simplifies to 6/2, which is 3.

Add all of these together. 40+3+4.5=47.5.

Answer:  " 14 " .

________________________

Step-by-step explanation:

________________________

First, let us simplify the expression on the "left-hand side" of the equation:

  →  -2(1 −4x) ;

________________________

Note the "distributive property of multiplication" :

      →  a(b + c)  =  ab + ac  .

________________________

As such, we can rewrite:  

      → -2(1 − 4x)  = (-2)(1) + (-2)(-4x) ;

                         =  - 2 + 8x ;

                       ↔  8x − 2 ;

________________________

Now, rewrite the entire expression:

 →  8x − 2 = 3x + 8 ;

________________________

Subtract "(3x)" from each side of the equation;

      and add "2" to each side of the equation:

________________________

 →  8x − 2 − 3x + 2 = 3x + 8 − 3x + 2 ;

to get:  

 →   5x = 10 ;

Now, divide each side of the equation by "5" ;

  to isolate "x" on side of the equation;

      & to solve for "x" ;

________________________

 →  5x/5 = 10/5 ;

to get:

________________________

 →  x = 2 .

________________________

Now, let us check our work:

________________________

Plug in "2" for all "x-values" into the original equation;

to see if the equation holds true;

that is, to see if each side of the original equation given has the same value;  

      when "x = 2" :

________________________

Note the given equation:

________________________

   →   -2[1 − 4x] = 3x + 8 ;

________________________

Start with the left-hand side:

   →  -2[1 − (4*2)} = -2(1 − 8) = -2(-7) = 14 .

Now, continue with the right-hand side:

   →  3(2) + 8 = 6 + 8 = 14 .

Answer:

A) $2356.00

Step-by-step explanation:

Principal, p = $1,500.00

Interest rate, r= 6.5%

Period, t = 7 years

compounded quarterly therefore, n = 4

Amount, A = P( 1 + r/n)^ n*t

A = 1500 ( 1 + 0.065/4)^ 4*7

A = 1500( 1 + 0.016)^28

A = 1500 ( 1.016) ^28

A = 1500 * 1.57

A = $2356.00

Answer:

Probability breaks down to this basic formula:

    desired outcome    

total possible outcomes

Also, you need to know there are 13 spades in a deck of cards.

So, on your first draw, the chances of getting a spade are:

13    (desired outcome: pick one of the 13 spades)

52    (total possibilities: 52 cards in the deck)

But on your second draw, if you don't replace the card, your chances of getting a spade are:

12

51

because you only have 12 spades left, and 51 cards total.

Then, on your last draw, the chances of getting a spade are down to:

11

50

Since each of these probabilities depend on each other, you multiply them up to get your overall probability:

13 * 12 * 11 =   1,716

52    51    50    132,600

This reduces, or you can just divide to get a decimal.

Step-by-step explanation:

Final answer:

To simplify the given expression, we combine like terms to get 8x+2.

Explanation:

This question can be answered by having basic understanding of rules of operations in algebra in general and about addition of expressions in particular

The expression

x+x+x+2x+x+x+2x can be simplified by combining like terms. This means adding together the coefficients of the same variables.

Combining

x terms gives 3x and combining 2x terms gives 4x. The expression becomes 3x+4x+x+x+2.

To further simplify, we can combine the like terms 3x, 4x and x to give

8x. Finally, we combine 8x and 2 to get the simplified expression 8x+2.

Therefore, the required answer of the question asked is 8x + 2.

To find the equivalent expressions to \( x + x + x + 2x + x + x + 2x + x + x + 2 \), we can perform some simplification by combining like terms.
Let's start by combining all the terms with \( x \) coefficients. When we add or combine like terms, we just sum their coefficients, keeping the variable \( x \) unchanged.
Here are the terms with \( x \) in them:
\( x + x + x + 2x + x + x + 2x + x + x \)
Now, let's add them up:
\( 1x + 1x + 1x + 2x + 1x + 1x + 2x + 1x + 1x = 11x \)
We just counted the number of \( x \)'s and there are eleven of them, hence \( 11x \).
Now let's consider the constant terms (the numbers without variables):
\( 2 \)
Since there is only one constant term, we don't need to combine it with anything else.
Now, we add the sum of the \( x \) terms to the constant term:
\( 11x + 2 \)
Therefore, the expression \( x + x + x + 2x + x + x + 2x + x + x + 2 \) simplifies to:
\( 11x + 2 \)
This is the equivalent expression to the original one given.
