Which expression represents, six times a number plus 8 times a number?

6a + 8

6 + 8 + a + b

48(ab)

6a + 8b

The equivalent factored form is A. 7x(2x + 5).

To factorize the expression 14x^2 + 35x completely, we look for the greatest common factor (GCF) of the terms and apply the distributive property.

In this case, the GCF of 14x^2 and 35x is 7x.

So, we can factor out 7x from the expression:

14x^2 + 35x = 7x(2x + 5)

Therefore, the equivalent factored form is A. 7x(2x + 5).

Answer:

Step-by-step explanation:

    Hence the size of the sample space is: [tex]7^4[/tex]

     since we have to fill in 4 places with the help of these 7 letters.

  so in first place we can select one out of any 7 letters, similarly for the second place as it is not mentioned that repetition is not allowed and the same can be done for third and fourth place.

Hence size of sample space is: [tex]7\times7\times7\times7=7^4[/tex]

 Probability=(Number of favourable outcomes)/(Total number of outcomes)

Hence here the total number of outcomes=[tex]7^4[/tex]

Total number of favourable outcomes=outcomes that the first three letters are vowels=[tex]3\times3\times3\times7[/tex] (since in the first place we have three choices for a vowel{A,I,0} similarly for second and third place and in the fourth place any one of the 7 letters could come)

Hence the probability(P) that the first three letters of the four-letter code are vowels is given by:

[tex]P=\dfrac{3\times3\times3\times7}{7\times7\times7\times7}=\dfrac{3\times3\times3}{7\times7\times7}=\dfrac{27}{343}[/tex]

Hence, the Probability is: [tex]\dfrac{27}{343}[/tex]

The total cost to produce 30 bicycles is $5599.89. The profit from first 30 bikes is $550.11. The marginal profit on the 31st bike is $126.57.

The marginal cost function given is 600/(0.3q+5). To find the total cost to produce 30 bicycles, we need to integrate the marginal cost from 0 to 30 and add the fixed cost of 2200.

The result of the integration is 2000*(ln|1+0.3q|). Calculating from 0 to 30 gives us 3599.89. Thus, the total cost to produce 30 bicycles considering the fixed cost is 5599.89.

The revenue of each bike sold is $205. So, the total revenue generated from selling 30 bikes is 30*$205 = $6150. The profit is then the difference between the revenue and the total cost, giving us $6150-$5599.89 = $550.11.

To find the marginal profit on the 31st bike, subtract the marginal cost at 31 bikes from the selling price. The marginal cost at 31 bikes is the marginal cost function evaluated at q=31, which is approximately $78.43, and hence, the marginal profit on the 31st bike is $205 - $78.43 = $126.57.

To find the total cost, multiply the quantity by the marginal cost function and add the fixed cost. To find the profit or loss, subtract the total cost from the revenue. The marginal profit can be found by subtracting the marginal cost from the selling price.

To find the total cost to produce 30 bicycles, you need to calculate the variable cost and add it to the fixed cost. The variable cost can be found by multiplying the marginal cost function by the quantity of bikes. So, the variable cost is (600/0.3*30 + 5) = 6105. Adding the fixed cost of 2200 gives us a total cost of 8305.

To find the profit or loss on the first 30 bicycles, we need to subtract the total cost from the revenue, which is the selling price multiplied by the quantity. So, the revenue is 205 * 30 = 6150. The profit or loss is then 6150 - 8305 = -2155, indicating a loss of $2155.

The marginal profit on the 31st bicycle can be found by subtracting the marginal cost from the selling price. So, the marginal profit is 205 - (600/0.3*31 + 5) = -55, indicating a loss on the 31st bicycle.

Answer:- A reflection of the line segment across the line y = –x .

Explanation:-

A reflection over the line y = -x, the x-coordinate and y-coordinate interchange their places and they are negated (the signs are changed).

Given :- A line segment has endpoints at (–1, 4) and (4, 1) such that it reflects produce an image with endpoints at (–4, 1) and (–1, –4).

(-1, 4)→(-4, 1) and

(4, 1)→(-1, -4)

Thus this shows a reflection of the line segment across the line y = –x.

Answer:

A reflection of the line segment across the line y = –x.

Step-by-step explanation:

Given : A line segment has endpoints at (–1, 4) and (4, 1).

To find : Which reflection will produce an image with endpoints at (–4, 1) and (–1, –4).

Solution : We have given that endpoints at (–1, 4) and (4, 1).

After reflection endpoints become  (–4, 1) and (–1, –4).

Reflection:   (–1, 4)  →→ (–4, 1)

                    (4, 1)→→→ (–1, –4).

We can see x coordinate become -y coordinate and y coordinate become -x coordinate.

(x ,y) →→ (–y, -x)

This is the a reflection of the line segment across the line y = –x rule of reflection .

Therefore, a reflection of the line segment across the line y = –x.

Answer: b)  the sum of six times a number and five

Step-by-step explanation:

The given expression is [tex]6b+5[/tex], where b represents any number.

The above expression has two terms combined by addition operation.

In the first term there is one variable b and 6 as coefficient of b and the second term is a constant term of 5.

Therefore, the correct description of the given expression [tex]6b+5[/tex] is " the sum of six times a number and five".

Option: b is the correct answer.

b) the sum of six times a number and five.

We are given an algebraic expression in term of a variable 'b' as:

                                  6b+5

As we could see that here there are two terms in an expression one is: 6b and the other is 5 which is separated by a summation sign.

  Hence, when 6 times of a number 'b' is added to 5 we get the given expression(i.e. 6b+5)

              Hence, the answer is:  Option: b

The loser had 5.5 points in the chess match.

To find out how many points the loser had in the chess match, we can set up an equation. Let's say the loser had x points. The winner was 4 points ahead, so the winner had x + 4 points. Since there were 15 games in total, we can set up the equation:

x + (x + 4) = 15

Combining like terms, we get:

2x + 4 = 15

Subtracting 4 from both sides, we get:

2x = 11

Dividing both sides by 2, we get:

x = 5.5

Therefore, the loser had 5.5 points in the chess match.

Answer:

radius of the cylinder is, 8 inches

Step-by-step explanation:

Volume of cylinder(V) is given by:

[tex]V = \pi r^2h[/tex]            .....[1]

where,

r is the radius of the cylinder and

h is the height of the cylinder.

As per the statement:

A cylinder has a volume of 320 pi cu. in. and a height of 5"

⇒[tex]V = 320 \pi[/tex] cubic inches and h = 5 inches

Substitute these values in [1] we have

[tex]320 \pi = \pi r^2 \cdot 5[/tex]

Simplify:

[tex]320 = r^2 \cdot 5[/tex]

Divide both sides by 5 we have;

[tex]64=r^2[/tex]

or

[tex]r^2 = 64[/tex]

⇒[tex]r = \sqrt{64} = 8 in[/tex]

Therefore, the radius of the cylinder is, 8 inches

Final answer:

To find the radius of the cylinder, use the formula for the volume of a cylinder, V = πr²h. Rearrange the formula to solve for the radius, and solve the equation to find the value of r.So,radius of cylinder r=8inches.

Explanation:

To find the radius of the cylinder, we can use the formula for the volume of a cylinder, which is V = πr²h. In this case, we need to solve for the radius, so we rearrange the formula as follows:

320π = πr²(5)

We can cancel out the π's on both sides of the equation:

320 = r²(5)

Divide both sides of the equation by 5:

64 = r²

Take the square root of both sides to solve for r:

r = √64

r = 8

Therefore, the radius of the cylinder is 8 inches.
