Answer:
Direct Variation:
- The number of family members are directly expenditures.
- The number of fruit in kg directly proportional to price of fruit.
- The number of selling products directly proportional to profit.
- The distance covered by body directly proportional to speed of body
- The acceleration produce in car directly proportional to change in velocity
- The income is directly proportional to working hours.
- The cost of electrical bill directly proportional to number of fans running in the house.
- The quantity of water fill in tank is directly to time for which the motor is switch on.
- The marks in study is directly proportional to hardworking.
- The bank balance is directly proportional to amount of saving.
Inverse Variation:
1. The bank balance is inversely proportional to expenditures.
2. The number of family members (which not work) are inversely proportional to amount of saving.
3.The working days required to complete the work are inversely proportional to number of labors.
4. The velocity of body is inversely proportional to time.
5. The acceleration is inversely proportional to time.
6. The acceleration of body is inversely proportional to mass of body.
7. The number of student fail in the class is inversely proportional to number of qualify teachers and hardworking.
8. The battery power is inversely proportional to time for which it used.
9. The ability of do work hard is inversely proportional to age of man after youngness to onward.
10. The number of mistake in work is inversely proportional to practice.
Explanation:
<u>Direct Variation</u>: A <u>relationship</u> where one quantity is a constant multiplied by another quantity is called <u>direct variation</u>.
<u>Inverse Variation</u>: <u>Inverse variation</u> is defiend as the relationship between two variables in which the resultant product is a constant. If a is inversely proportional to b, the form of equation is a = k/b, where k is constant. Inverse variation is known as the opposite of direct variation. If there an increas ein one variable, the other variable decreases in proportion so that the resultant product remains unchanged.
Answer:
m=2
Step-by-step explanation:
RS=2m+2
ST=3m+3
RT=15
m=2
RS=2(2)+2
RS=4+2
RS=6
ST=3(2)+3
ST=6+3
ST=9
Because S is in the middle of RT, if you add RS and ST together, you will get the length of RT.
6+9=15
First you should rearrange to get it in the form y = mx + c, and you do this by subtracting the 9x from both sides and dividing by 15, which gives you:
y = (-9/15)x + 3
Now you know the y-intercept is 3, so you can mark that on as a point.
Then, to graph the gradient of -9/15, you go along 15 spaces to the right and 9 spaces down, or 15 to the left and 9 spaces up, and you repeat this until you run out of room. Then you just join the dots

Answer:
he is less likely to pick a blue tile in the second bag
Step-by-step explanation:
divide 10 by 25 which will give you 40%
divide 75 by 250 which will give you 30%
this makes it less likely for Greg to pick blue from the second bag, as the first bag has a higher percentage chance
Answer: Division of Equality
Step-by-step explanation: In this equation, using division, we can find what y is by dividing 5 on both sides. Y equals to 15.
