What is the value of x? Enter your answer as a decimal.

Answer:

28.4

Step-by-step explanation:

Translate the statement into an equation, and then solve the equation.

Let x be the number we are looking for.

155% of what number is 44?

155% of x is 44

In math "of" usually means multiplication.

155% * x = 44

To change a percent to a decimal, divide by 100 which means move the decimal point 2 places left. 155% = 155/100 = 1.55

1.55x = 44

Divide both sides by 1.55 to solve for x.

1.55x/1.55 = 44/1.55

x = 28.4

Answer: 28.4 (rounded to the nearest tenth)

Answer:

22°

Step-by-step explanation:

If the mean is m and the standard deviation is s, then we can say that the temperatures that fall within 1 standard deviation of the mean will be:

m - s < temperatures < m + s

To we take the sum of mean and standard deviation: 24 + 4 = 28

and, the different of mean and standard deviation: 24 - 4 = 20

So, the temperature that is in between 20 and 28 is the temperature within 1 standard deviation of the mean.

This is the third answer, 22°

Answer:

Option A The zeros are the hot dog prices that give $0.00 profit (no profit)

Option C. Zeros at [tex]x=3(+/-)\sqrt{2}[/tex]

Step-by-step explanation:

we know that

The zeros of the function are the values of x when the value of y is equal to zero

In this problem

The zeros of the function are the price of a hot dog (in dollars) when the daily profit (in hundreds of dollars) of a hot dog stand are zero

we have

[tex]y=-2(x-3)^{2}+4[/tex]

Find the zeros

equate the equation to zero

[tex]0=-2(x-3)^{2}+4[/tex]

[tex]2(x-3)^{2}=4[/tex]

[tex](x-3)^{2}=2[/tex]

square root both sides

[tex]x-3=(+/-)\sqrt{2}[/tex]

[tex]x=3(+/-)\sqrt{2}[/tex]

Answer:

[tex]\frac{7x + 7}{(x-3)(x+4)}[/tex]

Excluded values are 3 and -4

Step-by-step explanation:

To simplify the expression multiply to create a common denominator.

Multiply the first fraction by (x-3) and the second fraction by (x+4).

[tex]\frac{3}{x+4} + \frac{4}{x-3}\\\\\frac{3(x-3)}{(x+4)(x-3)} + \frac{4(x+4)}{(x-3)(x+4)}[/tex]

[tex]\frac{3(x-3)}{(x+4)(x-3)} + \frac{4(x+4)}{(x-3)(x+4)} \\\\\frac{3(x-3) + 4(x+4)}{(x-3)(x+4)}\\\\\frac{3x - 9 + 4x + 16}{(x-3)(x+4)}\\\\\frac{7x + 7}{(x-3)(x+4)}[/tex]

Excluded values are values which make the denominator 0. This means (x-3)(x+4) cannot be 0. This means x cannot be 3 or -4. These are excluded values.

32/5 = 6 2/5

19/3 = 6 1/3

15/4 = 3 3/4

51/10 = 5 1/10

Step-by-step explanation:

Divide the top number and the bottom number. Example: 32 divided by 5 = 6 R2. Put the 5 under the 2. 2/5. So the total is 6 2/5.

Answer: [tex]x=\±2\sqrt{10}[/tex]

Step-by-step explanation:

To find the solutions of the quadratic equation given in the problem, you can apply the proccedure shown below:

- Subtract 40 from both sides of the equation.

- Multiply both sides of the equation by -1

- Apply square root to both sides of the equation.

Therefore, by applyin the steps above, you obtain:

[tex]40-x^2-40=0-40\\-x^2=-40\\(-1)(-x^2)=(-40)(-1)\\\\x^2=40\\\\\sqrt{x^2}=\±\sqrt{40}\\\\x=\±2\sqrt{10}[/tex]

Answer:

B. [tex]x+x+x[/tex]

Step-by-step explanation:

We are asked to find the equivalent expression to [tex]3x[/tex].

Our given expression stands for 3 times x. This means x is multiplied by 3 or we can say that x is added to itself 3 times.

We can rewrite [tex]3x[/tex] as [tex]x+x+x[/tex].

Upon looking at our given choices, we can see that only option B is the correct choice.

Answer:

Step-by-step explanation:

y = -7x - 3 is a linear function that follow y = mx+b. M is the slope or rate. Here m = -7 so the fish descends 7 meters per second. B is the y-intercept or starting position. Here the starting position is -3 so the fish starts 3 feet below sea level.

Answer: Third option.

Step-by-step explanation:

A ⊂ B this means that A is subset of B.

If A is subset of B (A ⊂ B), then all the elements of A belong to the subset B.

For example, the set of the Natural numbers is a subset of the Real Numbers.

Then, A ∩ B are all the elements that belong to AB at the same time.

A ∪ B are all the elements of A and all the elements of B.

But if we already said that A is inside of B, then:

 A ∩ B = A ≠ A ∪ B

A ∩ B = A ∪ B only happen when the set A=set B.

Therefore, the answer is: NEVER.

➷ Writing it out like this will help:

7 : 3 : 2

? : 3.75 : ?

So, 3.75 is 3 parts as per this ratio

Divide this amount by 3 to get 1 part in the ratio

3.75 / 3 = 1.25

Now simply multiply all the other ratios by this value to find how much the others get:

1.25 x 7 = 8.75

1.25 x 2 = 2.5

Paula gets £8.75 and Henry gets £2.50

The amount altogether would be their individual amounts added together:

8.75 + 2.50 + 3.75 = 15

The total amount of money is £15.

Answer:The symbol means greater than

Step-by-step explanation:

Answer:

The symbol '>' is always read from left to right, and it means greater than.

Step-by-step explanation:

In mathematics, such relationships between the two expressions which are not equal to one another are said to be inequalities.

To express these inequalities, certain symbols are used which include the following ones:

<, >, ≤, ≥ and ≠

All these symbol are always read from the left side towards the right side and the symbol '>' means greater than.

L.s.f=linear scale factor.

A.s.f=area scale factor.

L.s.f=length of prism 1/length of prism 2

L.s.f=3/8.

let area or prism 1=x

A.s.f=(L.s.f)^2

A.s.f=(3/8)^2

=9/64

9/64=x/256

x=(9×256)÷64

Step-by-step explanation:

the perimeter of the triangle shown on the coordinate plane to the nearest tenth of a unit is 21 units. Therefore, option c is the correct answer.

To find the perimeter of the triangle shown on the coordinate plane, we need to calculate the lengths of each side and then add them together.

Step 1: Calculate the length of the first side.

Using the distance formula, the length of the side connecting (-3, 3) and (3, -3) is:

√[(3 - (-3))^2 + (-3 - 3)^2] = √[6^2 + (-6)^2] = √[36 + 36] = √72.

Step 2: Calculate the length of the second side.

Using the distance formula, the length of the side connecting (3, -3) and (3, 3.5) is:

√[(3 - 3)^2 + (3.5 - (-3))^2] = √[0^2 + 6.5^2] = √[0 + 42.25] = √42.25.

Step 3: Calculate the length of the third side.

Using the distance formula, the length of the side connecting (3, 3.5) and (-3, 3) is:

√[(-3 - 3)^2 + (3 - 3.5)^2] = √[-6^2 + (-0.5)^2] = √[36 + 0.25] = √36.25.

Step 4: Calculate the perimeter by adding the lengths of the sides.

Perimeter = √72 + √42.25 + √36.25.

Now we can simplify the answer to the nearest tenth:

Perimeter ≈ 8.5 + 6.5 + 6 = 21.

Therefore, the perimeter of the triangle shown on the coordinate plane to the nearest tenth of a unit is 21 units.

Therefore, option c is the correct answer.

Do 55,427 divided by 67,103 which is 0.825998838 then multiply that by 100 to get 82.5998838 then round up to the nearest tenth to get 83 percent

The percentage of people from the West that are insured is 83%.

Given that, the U.S. government collects information on Americans who do not have health insurance.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Number people insured from west region = 55,427

Total number of people from west region = 67,103

So, percentage = 55,427/67,103 × 100

= 0.8259 × 100

= 82.59

≈ 83%

Therefore, the percentage of people from the West that are insured is 83%.

Julie can type 3 pages in x minutes; to find the time to type 11 pages, set up a proportion and solve, resulting in 11x/3 minutes.

Since Julie can type 3 pages in x minutes, the rate at which Julie types is 3 pages per x minutes. If we want to find out how many minutes it will take her to type 11 pages, we simply set up a proportion based on her typing rate:

3 pages / x minutes = 11 pages / y minutes

To solve for y, which is the time it will take to type 11 pages, we cross-multiply and get:

3y = 11x

Then, we divide both sides of the equation by 3, yielding:

y = 11x / 3

The answer is option (e): 11x / 3.
