Answer:

She purchased the item at a price of Rs 1,406.

Step-by-step explanation:

5% of discount:

This means that she paid 100% - 5% = 95% = 0.95 of the original price of x, that is, 0.95x, and 0.05x was the discount.

Original price:

She got the discount amount of Rs 74.

74 is 5% of the original price, that is:

\(0.05x = 74\)

\(x = \frac{74}{0.05}\)

\(x = 1480\)

What price she purchased:

74 subtracted from the original price, that is, x - 74. So 1480 - 74 = 1406.

She purchased the item at a price of Rs 1,406.

Step-by-step explanation:

There are many solutions because 0=0.

The sample size must be more than 30 and the sample must be chosen at random for this confidence interval to hold true. The sample size in this example is 95, and the students were chosen at random, thus both of these requirements are satisfied.

Calculating a percentage involves dividing an item by its sum and multiplying the result by 100. (Value/Total Value)100% is the formula for calculating percentages.

We must divide the value by the entire value to find the percentage, and then multiply the resulting number by 100.

The percent change is -25% that is decreased.

What is percent change ?

A percentage is a portion of a whole expressed as a number between 0 and 100 rather than as a fraction. All of something is 100 percent , half of it is 50 percent , none of something is 0 percent.

Percent change equals the change in value divided by absolute value of original value and multiplied by 100.

Negative precent change :

When the change goes on decreasing, i.e. final value is less than original.

Positive percent change :

When the change goes on increasing i.e. final value is more than original.

In given que,

initial value = 8

final value = 6

change in value = 6-8

                           = -2

So, percent change = -2/8 *100 = -25%

It takes the student 5/6 hours to complete the project at the same rate

Rate is the amount per unit time of a variable

Since student completes ⅘ of a math project in ⅔ hour, we need to find the rate at which he completes the math project.

So, the rate is r = amount /time

Since

Substituting the values of the s variables into the equation, we have that

rate, r = amount/time

= 4/5 ÷ 2/3 h

= 4/5 × 3/2 h

= 2/5 × 3/1 h

= 6/5 per hour

Now, since the student  completes ⅘ of a math project in ⅔ hour, the rest fo the math project to complete is n = 1 - 4/5

= (5 - 4)/5

= 1/5

So, the time he takes to complete the rest of the project is T = amount/rate

Since

So, substituting the valuies of the variables into the equation, we have

T = amount/rate

= 1/5 ÷ 6/5 per hour

= 1/5 × 5/6 h

= 1/6 h

So, the total time it takes the student to complete the project is T' = 2/3 h + 1/6 h

= (4 + 1)/6 h

= 5/6 h

So, it takes 5/6 hours

Answer:

(B) Between 6 and 9 minutes, Sameen's distance from work is decreasing

Step-by-step explanation:

Looking at the graph, we want to make sure we are looking at the right axis.

The x-axis, the horizontal one, is minutes.

The y-axis, the vertical one, is distance from work.

We can see that while x is between 6 and 9 minutes, the graph slopes downwards. This signifies a decrease in distance from work.

So between 6 and 9 minutes, Sameen's distance from work is decreasing.

Answer:

1.9 gallons of 80% and 5.7 gallons of 20%

Step-by-step explanation:

x gallons of 80% alcohol solution is mixed with y gallons of 20% alcohol to make 7.6 gallons of 35% alcohol solution.

Based on the given, we get two equations:

Let's substitute y with y = 7.6 - x:

Then we find the value of y:

So the answer is:

Answer:

1.9 gallons of the 80% solution.

5.7 gallons of the 20% solution,

Step-by-step explanation:

Let the volumes of the 80% and 20 % solutions be x  and y gallons.

Then:

x  +  y = 7.6.

Also, using amounts of pure alcohol:

0.8x + 0.2y = 7.6 * 0.35

0.8x + 0.2y = 2.66           Multiplying this equation by -5:

-4x - y = - 13.3                   Adding this to the first equation:

-3x = -5.7

= 1.9 gallons.

y = 7.6 - 1.9

=  5.7  gallons.

x = 12, z = 109

Step-by-step explanation:

x = 144/12 = 12

z = 180 - 71 = 109

It is important to note that this equation assumes a constant density of seawater, which is not always the case in the deep ocean. In addition, the pressure at a given depth can vary depending on factors such as temperature and salinity. This equation should be used with caution and in conjunction with other measurements and data analysis techniques.

The given equation for pressure in pounds per square foot at a depth of d feet is P = 14 + 4d/9. We are given that the pressure measured by the scientific team is 306 pounds per square foot. To find the depth at which this pressure is measured, we need to solve the equation for d.

Substituting P = 306 in the equation, we get:

306 = 14 + 4d/9

Multiplying both sides by 9, we get:

2754 = 126 + 4d

Subtracting 126 from both sides, we get:

2628 = 4d

Dividing both sides by 4, we get:

d = 657 feet

The scientific team is measuring the pressure at a depth of 657 feet below the surface of the ocean.

Answer:

Step-by-step explanation:

since we know that triangles have 180° we know that 116° is two much if it's doubled  2*116 = 232° so that angle has to be the single angle and the left over of 180 - 116  is the left over amount that is even divided into the last two angles so   180 - 116 = 64 / 2 = 32°  so the triangle is made up of  116 + 32 + 32 degree angles

The solutions to the quadratic equation, -9x² + 49 = 0, are: C. x = 7∕3, –7∕3.

Given the quadratic equation, -9x² + 49 = 0, we can factorize to find the roots (the values of x) as shown below:

-9x² + 49 = 0

-(9x² - 49) = 0

Divide both sides by -1

-(9x² - 49)/-1 = 0/-1

9x² - 49 = 0

9x² - 49 + 49 = 0 + 49

9x² = 49

Divide both sides by 9

9x²/9 = 49/9

x² = 49/9

Take the square root of both sides

√x² = √(49/9)

x = ±7/3

Therefore, the solutions to the quadratic equation, -9x² + 49 = 0, are: C. x = 7∕3, –7∕3.

total cost = $22.4 + $1.12 = $23.52

Step-by-step explanation:

Mr McNeil bought 2 magazines for $7.45 and 1 book for $14.95 . The sales tax is 6% . The total cost of Mr McNeil can be calculated as follows.

He bought 2 magazines for $7.45  .This means the sum of the prize of the 2 magazine he bought is $7.45 and the prize for the single book he bought is $14.95.  The total cost of the items he bought excluding the sales tax is the sum of the whole items he bought.

total cost excluding sales tax = $7.45 + 14.95 = $22.4

The sales tax is 5% which can be calculated as follows

5/100 × 22.4 = 112/100 = $1.12

The total cost of Mr McNeil purchase including his sales tax is

total cost = $22.4 + $1.12 = $23.52

c.40:50=4:5

By using the Unitary Method we get the number of children who went on an excursion was 63. Thus, the total number of children at school is 90.

We are given that,

No. of children who stayed at school is 27,

Also, 70% of the children went on an excursion.

Suppose, the total number of children in percentage is 100%

Out of which 70% went on an excursion

Thus, the children who stayed at school is 100% - 70% = 30%

By using the Unitary method, we can find out the number of 70% of children.

If 30% of the children are 27

Then 70% of the children are = 27 × 100

                                                        30

                                                 = 63

∴ the total no. of children in the school = 27 + 63

                                                                 = 90
