Answer:

x = 10

Step-by-step explanation:

If the selling prices of 20 pens are equal to the cost price of 25 pens, what is the gain percentage?

Answers

The gain percentage is 25%

[tex]\huge\bold\red{Answer:-}[/tex]

No(0)Let the cost price of the 20 pens be ₹100.

Cost of each pen=₹100/20=₹5

Selling price of each 25 pens sold=₹100/25=₹4.

If cost of each pen. = 5=100%

..selling price of each pen. = 4= ?%.

Find x- and y-intercepts. Write ordered pairs representing the points where the line crosses the axes.

y= 1/3 x− 2/3

Answers

Answer:

y-intercept = (0,-2/3)

x-intercept = (2,0)

Step-by-step explanation:

*X-intercept touches the x-axis & y-intercept touches the y-axis*

You can identify the y-intercept by looking at the equation.

The slope is 1/3x and the y-intercept is -2/3.

I'm not sure how to solve for the x-intercept, but you can make a graph with the y-intercept and the slope points. By doing this you should be able to find the x-intercept.

Hope this helped!!!  :)

PS: Check out the Desmos Graphing Calculator

This website helps a lot with these types of problems. You can type the equation, and it will show you a graph. If you look at the graph, you'll be able to determine the slope, the x-intercept, and the y-intercept.

Harry put blue and green marbles in a bag. Exactly 3/4 of the marbles in the bag are blue. Which of the following could be the total number of marbles in the bag.
A. 3
B. 6
C. 7
D. 8

Answers

Answer:

D

Step-by-step explanation:

Because when u multiply 3/4 times A,B,C it gives you a decimal, when u multiply 3/4 by 8 you get 6 a whole number.

The total number of marbles in the bag could be (d) 8

How to determine the possible total?

We have:

Blue proportion = 3/4

This means that the green proportion is

Green proportion = 1 - 3/4

Evaluate

Green proportion = 1/4

Express as ratio

Blue: Green = 3/4 : 1/4

Simplify

Blue: Green = 3 : 1

Add the ratios

Total = 3 + 1

Total = 4

The above means that the total number of marbles in the bag is a multiple of 4

i.e. 4, 8, 12, 16, 20......

Hence, the total number of marbles in the bag could be (d) 8

Show that StartFraction r 1 Over r 2 EndFraction equals StartFraction omega 2 Over omega 1 EndFraction r1 r2

Answers

Answer:

r1/r2 = 2ω2/ω1

Step-by-step explanation:

The velocity of each pulley is expressed as v = ωr where;

v is the linear velocity of the pulley

ω is the angular velocity of the pulley

r is the radius of the pulley.

For the two pulleys, the velocity I'd both pulleys are the same.

v1 = v2

v1 is the linear velocity of first pulley

v2 is the linear velocity of the second pulley.

v1 = ω1r1

v2 = 2ω2(r2)

r1 and r2 is the radius of pulley 1 and pulley 2 respectively.

Since v1 = v2

ω1r1 = 2ω2(r2)

Divide both sides by r2

ω1r1/r2 = 2ω2(r2)/r2

ω1r1/r2 = 2ω2

Divide both sides by ω1

ω1r1/r2/ω1= 2ω2/ω1

r1/r2 = 2ω2/ω1
