Find y when x=5, if y varies directly as x and y= 5 when x=3.5

Answers

Answer 1
Answer:

Answer: 3.5

Step-by-step explanation:

In variation, and from the above question,

y ∞ x ,

y = kx , where k is the constant of proportionality

first find the constant k

5 = 5k

Therefore

k = 1

Now to find y , substitute for k and x in the first equation above

y = kx

y = 1 x 3.5

y = 3.5

Solve -1 4/5 x= 9.
A) 5
B) 1/5
C) -5
D) -1/5

Answers

Answer:

C) -5

Step-by-step explanation:

-1 4/5 x= 9.

Change the left side to an improper fraction

(5*1+4)/5 = 9/5

-9/5 x =9

Multiply each side by -5/9 to isolate x

-5/9 * 9/5x = 9 * (-5/9)

x = -5

Answer:

C) -5

Step-by-step explanation:

-1 4/5 x= 9.

Change the left side to an improper fraction

(5*1+4)/5 = 9/5

-9/5 x =9

Multiply each side by -5/9 to isolate x

-5/9 * 9/5x = 9 * (-5/9)

x = -5

Morgan fills a 1-liter jar with water from the pond. She uses a 100-milliliter cup to scoop water out of the pond and pour it into the jar. How many times will Morgan scoop water from the pond to fill the jar?

Answers

Answer:

Number of scoops required = 10

Step-by-step explanation:

Morgan fills a 1-liter jar with water from the pond.

Capacity of Jar = 1 liter

She uses a 100-milliliter cup to scoop water out of the pond and pour it into the jar.

Capacity of cup used to pour in to the Jar = 100 milliliter

We have relation

         1 liter = 1000 ml

         1 liter = 100ml x 10

         Capacity of Jar = Capacity of cup used to pour in to the Jar x 10

Number of scoops required = 10

1000 times I think
