what is the answer to x over 7 = 89

Answer:

B

Step-by-step explanation:

Because they have same volume we have :

V(boxA)=2*3*6=36[tex]in^3[/tex]

V(boxB)=3*4*l=12l

V(boxA)=V(boxB)

So we have this equation :

36=12l

Divide by 12

l=3

Answer:

h has a coefficient 1 so u will afd 6h +h=7h

For this case we have the following expression:

[tex]2x ^ 2 + 2x ^ 3[/tex]

The terms are not similar, so they cannot be added.

Examples of similar terms:

[tex]x ^ 3 + x ^ 3 = 2x ^ 3\\3x ^ 4 + 2x ^ 4 = 5x ^ 4[/tex]

Then, the expression given can only be rewritten as:

[tex]2 (x ^ 2 + x ^ 3)[/tex]

This is taking common factor 2 to both terms.

Answer:

[tex]2 (x ^ 2 + x ^ 3)[/tex]

Answer:

69°

Step-by-step explanation:

The three interior angles in a triangle will always add up to 180°, so we have:

43°+x+(x-1)=180°

43°+2x-1°=180°

2x=180°-43°+1°

2x=138°

Step-by-step explanation:

sin C = 7/25 or 0.28

cos C = 24/25 or 0.96

tan C = 7/24 or about 0.292

lmk if u want me to explain how trigonometric functions work

The ratios for sin C, cos C, and tan C in a right triangle are y/h, x/h, and y/x respectively, where y is the opposite side, x is the adjacent side, and h is the hypotenuse.

To write ratios for sin C, cos C, and tan C in a right triangle, you need to refer to the lengths of the sides of the triangle relative to angle C. If we denote the opposite side to angle C as y, the adjacent side as x, and the hypotenuse as h, the ratios are defined as follows:

In a practical scenario, if you know the magnitude of one side and the direction angle, you can use these ratios to find the scalar components of a vector in a coordinate system, solve problems involving the Law of Sines and Law of Cosines, or analyze wave functions in physics. For example, the Law of Sines relates the lengths of the sides of a triangle to the sines of its angles as follows:

 a/sin A = b/sin B = c/sin C

Where a, b, and c are the sides of the triangle opposite to angles A, B, and C, respectively.

Answer:

A. The graph approaches –3 as x approaches infinity.

Step-by-step explanation:

when looking at the problem F (x) + 3x/x-4 the answer would lead up to..

Finding the domain by finding where the function is defined. The range is the set of values that correspond with the domain.

Domain:  

( − ∞ , 4 ) ∪ ( 4 , ∞ ) , { x | x ≠ 4 }

Range:  ( − ∞ , − 3 ) ∪ ( − 3 , ∞ ) , { y | y ≠ -3 }

are what it leads to and seeing the range -3 would have x as infinite/ -∞

so A is the correct option to me

The statement that describes the behavior of the function f(x) = 3x/4-x is The graph approaches 0 as x approaches infinity.

Option B is the correct option.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The statement "The graph approaches 0 as x approaches infinity" is the correct statement that describes the behavior of the function f(x) = 3x/(4-x).

We can use the limit definition of approaching infinity.

When x becomes very large (positive or negative), the term 4 - x in the denominator becomes very small, approaching zero.

As a result,

The fraction 3x/(4-x) approaches zero as x approaches infinity.

This can be confirmed using L'Hopital's rule, which gives the limit of the function as 0/1, or simply by observing the graph of the function.

Thus,

The graph approaches 0 as x approaches infinity.

Step-by-step explanation:

Final answer:

The percent change in total computer sales from June to July cannot be calculated without the specific numerical sales data for each model. We need the quantities sold in May and June to determine the rate of change and project this to July.

Explanation:

To determine the percent change in total computer sales from June to July, based on the provided sales chart data, we first need to calculate the change from May to June for each computer model separately. If we assume that the sales data numbers in the chart represent the quantity of computers sold, we can take the difference in sales of each model between the two months and then sum these differences to get the total change in sales. Afterward, we'll need to express this total change as a percentage of the total sales in June.

However, the actual sales data with quantity figures are not provided; hence, we cannot calculate the exact percent change. The question seemingly requires specific numerical data to calculate the change in percentage, which is not included in the text above. Without such data, it is impossible to provide a step-by-step solution to the question regarding calculating the percent change in total computer sales.

The slope of a line is given by rise over run. The slope of the board leaning against the building is 4.5; given by the height it reaches (18 feet) divided by the distance from the base of the building to the base of the board (4 feet).

The subject of your question is the slope of a line in a mathematical context, specifically when dealing with the Algebra of Straight Lines. First, let's recall what slope is. The slope of a line, commonly represented as m, is the measure of the vertical change (rise) for each unit of horizontal change (run).

To find the slope of the board leaning against the building, we can take the rise over the run. Here, the rise is the height of the building which the board reaches - 18 feet. The run is the distance from the building to the board's base on the ground - 4 feet. Hence, the slope m of the board would be calculated as follows: m = rise/run = 18/4 = 4.5.

A positive slope indicates that the line rises from left to right, like the board leaning against the building. So, the slope of the board as a positive number is 4.5.

Answer:

g-1(x) = -x/3 - 6.

Step-by-step explanation:

Let g(x) = y = -3(x + 6)

y = -3x - 18

3x = - y - 18

x =  -y/3 - 6

Now replace x by the inverse g-1(x)  and y by x, so

g-1(x) = -x/3 - 6.

The fraction is 5/15, which simplifies to 1/3. So Andy ate one third of the tuna sandwich.

The student's question involves determining the fraction of the tuna sandwich that Andy ate. Andy cut a tuna sandwich into 12 more pieces than the chicken sandwich and the total number of pieces was 18. Since tuna has 12 more pieces, we let the number of chicken pieces be x. Hence, the tuna pieces would be x + 12. The equation then is x + (x + 12) = 18. Solving this, we get x = 3 (chicken pieces) and x + 12 = 15 (tuna pieces).

Andy ate 5 pieces of the tuna sandwich, so the fraction of the tuna he ate is 5 out of the total tuna pieces, which is 15. Therefore, the fraction is 5/15, which simplifies to 1/3. So Andy ate one third of the tuna sandwich.

Answer:

0.58

Step-by-step explanation:

Answer:

No.

Step-by-step explanation:

On the number line, a number is greater than a number to its left. For example, 3 is to the left of 5, so 5 is greater than 3.

On the number line, -3.5 is to the left of -1.5, so -1.5 is greater than -3.5.

After comparing the given two negative numbers we conclude that,

the number -3.5 is not greater than -1.5.

A negative number is one that always has a value lower than zero and is denoted by the minus (-) symbol.

The given numbers are,

-3.5 and  -1.5

Subtract -1.5 from -3.5

-3.5 - (-1.5)

Remove bracket by multiplying signs,

-3.5 + 1.5

= -2.0

Now it can be written,

-3.5 = -1.5 - 2.0

Since,

-1.5 - 2.0 < -1.5

Therefore,

-3.5 < -1.5

Hence,

The number -3.5 is not greater than -1.5.

The markup percentage on the shoes that were bought for $50 and sold for $80 is 60%.

To calculate the markup percentage, you subtract the original cost from the selling price and then divide that number by the original cost. Finally, you multiply the result by 100 to get the percentage.

The formula looks like this: ((Selling Price - Original Cost) / Original Cost)×  100. Let's apply this formula to your question.

The store bought the shoes for $50 and sold them for $80. So the markup in dollars is

$80 - $50 = $30

Now, let's convert this to a percentage:

Markup Percentage =

[tex]= \frac{80-50}{50} \times 100 \\\\= \frac{30}{50} \times100\\\\ = 60\%[/tex]
