Answer:

He should sell each pen of Rs.0.8625 so as to make a gain of 15%

Step-by-step explanation:

  • Cost price of 100 pens = Rs.75
  • Cost price of 1 pen=\frac{75}{100} = 0.75
  • Gain%= 15%

Gain=15%X 0.75= 0.1125

SP = CP+Gain = 0.75+0.1125=0.8625

<u>So, He should sell each pen of Rs.0.8625 so as to make a gain of 15%</u>

Answer:

The option which represents the inequality is option D ; stated as x ≥ 0

Step-by-step explanation:

The marked or dotted position is 0 ; which represents the position of x, when graphing inequality statements, if the point IS SHADED, then it means GREATER THAN EQUAL TO.

Option A is incorrect, the inequality sign is not the same as the direction of the arrow.

Option B, says LESS THAN EQUAL TO, instead of GREATER THAN EQUAL TO

Option C SAYS GREATER THAN instead of GREATER THAN EQUAL TO.

Therefore, Option D is the correct expression which means x is GREATER THAN EQUAL TO.

What is the measure in degrees for the central angle of a circle whose radius is 9 cm and intercepted arc length is 7.2 cm?
Marina CMI [18]

Answer:

Therefore the measure of the central angle is 45.86°.

Step-by-step explanation:

Given:

Radius = 9 cm

arc length = 7.2 cm

pi = 3.14

To Find:

Central angle = θ =?

Solution:

If the θ  measured in degree then the arc length is given as

\textrm{arc lenght}=\dfrac{\theta}{360\°}\times 2\pi r

Where r = radius, θ = Central angle

On substituting the values we get

7.2=\dfrac{\theta}{360}\times 2\times 3.14\times 9\\\\\theta=\dfrac{2592}{56.52}=45.8598=45.86\\\therefore \theta=45.86\°

Therefore the measure of the central angle is 45.86°.

Suppose that x and y vary inversely, and x = 2 when y = 7. Write the function that models the inverse variation.
irga5000 [103]
Since, in this case, we have 4 options then you just need to substitute each number.
A. y = 5/x
B. y = 14/x
C. y = 9/x
D. y = 3.5x
 
We know that x= 2 when y=7. So...
A. y = 5/x
    7=5/2
    7=2.5 
   This is false.

B. y = 14/x
    7= 14/2
    7=7
  This is right, So True.

C. y = 9/x
     7=9/2
     7=4.5
    False

D. y = 3.5x    7=3.5(2)
    7=7
  This one is also true.

In this case we look for definition.

he statement " <span>y </span>varies inversely as <span>x </span>means that when <span>x </span>increases, <span>y </span>decreases by the same factor. In other words, the expression <span>xy </span>is constant:
xy = k   

where k is the constant of variation.

We can also express the relationship between x and y as:

y =  k/x 

where k is the constant of variation.
