Answer:

[tex](34)[/tex]

Step-by-step explanation:

We are looking for what number times .50 makes the equation true.

So, just do backwards equation:

[tex]52 - 35[/tex]

[tex]==> 17[/tex]

Thus, meaning that what multiplied by 0.50 is equal to 17?

[tex]0.50 * 34[tex]

[tex]==> 17[tex]

Put any Variable in between the parentheses, for example x.

Step-by-step explanation:

1. Move the Constant 35 to the other side of the problem, and flip it's sign.

0.5(×)=52-35

2. Subtract the numbers

0.5×=17

3. Divide both sides of the equation by 0.5

×=34

Answer:

x = 3.65

Step-by-step explanation:

7.4x + 5 = 32

-5              -5

7.4x = 27

-----    -----

7.4     7.4

x = 3.64864865

This rounds to 3.65

x = 3.65

Answer:

B. No solutions.

Step-by-step explanation:

Let's try solving it:

3(x + 8) = 3x + 4

3x + 8 = 3x + 4.

There are no solutions  because if we simplify we get an absurd result. Subtract 3x from both sides of the equation:

3x - 3x + 8 = 3x - 3x + 4

8 = 4.

There are no solutions for x in this equation.

To solve this equation, we need to combine like terms and isolate the variable. Here are the steps:

Since 23 does not equal 4, these two sides are not equal. Therefore, there are no solutions for x in this equation.

Answer: 17

Step-by-step explanation:

Gabby's savings over 'b' weeks can be written as an inequality 50 + 20b > 400. Simplifying this, we find that Gabby has to save up for at least 18 weeks to save more than $400.

Gabby's savings can be represented as 50 + 20b, with 'b' being the number of weeks. For her to save more than $400, we can write this inequality 50 + 20b > 400. Subtract 50 from both sides to simplify the inequality and we get 20b > 350. To find the least number of weeks, divide both sides by 20 to solve for b and we get b > 17.5. However, since 'b' must be a whole number (because you can't have half a week), the least number of weeks Gabby must save is 18 weeks.

Answer:

Step-by-step explanation:

The mean (or average) of a set of numbers can be found with the following formula:

[tex]Mean = \frac{A_{1} + A_{2} + ... + A_{N}}{N}[/tex]

For this problem, we have five numbers, so we add them together and divide by 5:

[tex]Mean = \frac{92 + 85 + 78 + 97 + 88}{5}[/tex]

[tex]Mean = \frac{440}{5}[/tex]

[tex]Mean = 88[/tex]

Answer:

88%

Step-by-step explanation:

Emma took tests of her 5 chapters throughout the year.

She received  the score on the five tests

92%, 85%, 78%, 97% and 88%

We have to calculate the average (mean) of her final grade.

average =  [tex]\frac{\text{addition of all grades}}{\text{total number of tests}}[/tex]

=  [tex]\frac{92+85+78+97+88}{5}[/tex]

=  [tex]\frac{440}{5}[/tex]

= 88%

Her final grade would be 88%.

The classification of the numbers into rational and irrational are:

1. Pi is irrational

2. 7 squared is irrational

3. 7.1234... is irrational

1) π is a mathematical expression whose approximate value is 3.14159365…

The given value of π is expressed in decimal which is non-terminating and non-repeating. As the value is non-terminating it shows the nature of irrational numbers. Hence, π is not a rational number

2) 7 squared is not a perfect square and as such it will have non-terminating and non-repeating decimal and so it is irrational.

3) 7.1234... is an irrational number because it is non-terminating and non-repeating decimal.

The area of the room = (40 x 24) - (20 x 12)

Area = 960 - 240 = 720 square feet

Divide square feet by width of a strip:

720 / 12 = 60 linear feet.

The answer is D.

Answer : The correct option is, (D) 60

Step-by-step explanation :

First we have to calculate the area of room.

Area of room = Area of big rectangle + Area of small rectangle

Area of rectangle = Length × Width

Area of room = (40 × 12) + (20 × 12)

Area of room = 720 square feet

Now we have to calculate the number of linear feet will he need to buy.

Number of linear feet = [tex]\frac{\text{Area of room}}{\text{Width of carpet strips}}[/tex]

Number of linear feet = [tex]\frac{720}{12}=60[/tex]

Thus, the number of linear feet will he need to buy is, 60

Final answer:

To create a 35% saline solution by mixing a 50% and a 30% solution, the nurse needs to use 6000cc of the 30% solution.

Explanation:

The question asks how much of a 30% saline solution a nurse needs to mix with 60cc of a 50% saline solution to achieve a final solution concentration of 35%. To solve this problem, let's denote the volume of the 30% solution needed as x cc. Using the concept of weighted averages for concentrations, we can set up the following equation:

(60cc × 50%) + (x cc × 30%) = (60cc + x cc) × 35%

Solving this equation, we get:

3000 + 0.3x = 0.35(60 + x)

3000 + 0.3x = 21 + 0.35x

Subtracting 0.3x from both sides:

3000 = 21 + 0.05x

Subtracting 21 from both sides and dividing by 0.05:

x = 6000 cc

Therefore, the nurse should use 6000cc of the 30% saline solution to achieve the desired concentration.

Step-by-step explanation:

Paulo's time in standard notation is 15,600 seconds. Miguel ran the marathon in a shorter time of 15,360 seconds. For the given equations, A) and B) each have one solution (x=3 and x=10, respectively), while C) has an infinite number of solutions.

To convert Paulo's time from scientific to standard notation, we multiply 1.56 by 10 to the power of 4. This equals 15,600 seconds. Next, we need to convert Miguel's time to seconds to directly compare the two durations. Miguel ran for 4 hours and 16 minutes, which is equal to (4 × 3600) + (16 × 60) = 14,400 + 960 = 15,360 seconds. Therefore, Miguel ran the race in a shorter amount of time by 240 seconds.

For question 2, we solve the following equations:

For equation A) 2x + 4(x - 1) = 2 + 4x, after simplifying we get 2x + 4x - 4 = 2 + 4x. The 4x terms cancel out and we are left with 2x - 4 = 2. Solving for x gives x = 3. This equation has one solution.

For equation B) 25 - x = 15 - (3x + 10), simplifying gives 25 - x = 5 - 3x. Solving for x yields x = 10, so this equation also has one solution.

For equation C) 4x = 2x + 2x + 5(x - x), simplifying results in 4x = 4x, which is true for all values of x. Therefore, this equation has an infinite number of solutions.

As question 3 involves an image that we cannot see here, this part of the student's question has been left unanswered.

Answer:

if you're asking what 21 divided by 40 is then it's 0.525

Step-by-step explanation:

Answer:

Step-by-step explanation:

We know:

1min = 60s → 3min = (3)(60s) = 180s

40s : 3min = 40s : 180s = (40/20) : (180/20) = 2 : 9

$1 = ¢100 → $3 = (3)(¢100) = ¢300

$3 : ¢65 = ¢300 : ¢65 = (300/5) : (65/5) = 60 : 13
