Write the following comparison as a ratio reduced to lowest terms 9 nickels to 3 dimes

Mathematics
1 answer:
ludmilkaskok [199]3 years ago
7 0

Answer:

3 : 2

Step-by-step explanation:

We are asked to calculate as a ratio 9 nickels to 3 dimes reduced to lowest terms.  

One nickel means $0.05 and one dime means $0.10.

So, 9 nickels is equal to $(0.05 × 9) = $0.45

And 3 dimes is equal to $(0.10 × 3) = $0.30

Therefore, the ratio will become 0.45 : 0.30 ≡ 3 : 2 (Answer)

Answer:

1, 1/2, 1 1/2

Step-by-step explanation:

Question 1

Question 2

9 divided by 20 is 0.45

So the answer is closest to 1/2

Question 3

7 divided by 5 is 1.4

So the answer is closest to 1 1/2

Julian study a dog walking business over his summer break. He charges $10 for every 1/3 hour he walks a dog if he increases his
Genrish500 [490]

Answer:

The amount of increase per \frac{1}{3}  hour by $1.

Step-by-step explanation:

Julian charges $10 for every \frac{1}{3} hour he walks a dog.

He increases his fee by 10%

Now we have to find 10% of $10

Amount increased = \frac{10}{100} .10 = 1

So the amount increased by $1.

The amount of increase per \frac{1}{3}  hour by $1.

Solve the system using elimination.
KIM [24]
We can't eliminate as is so we have to change something up there in the equations to get either the x values the same number but opposite signs, or the y values the same number but opposite signs.  I chose to change the y values to the same number but different signs. In the first equation y is -3y and in the second one, y is -8y. The LCM of both of those numbers is 24, so we will multiply the first equation by an 8 (8*3=24) and the second equation by 3 (3*8=24) but since they are both negative right now, one of those multiplications has to involve a negative because - * - = +. Set it up like this:
8(-10x - 3y = -18)
-3(-7x - 8y = 11)
Multiply both of those all the way through to get new equations:
-80x - 24y = -144
 21x  +24y = -33
Now the y's cancel each other out leaving only the x's:
-59x = -177 and x = 3.  Now plug that 3 into either one of the original equations to find the y value.  Either equation will work; you'll get the same answer using either one. Promise. -7(3) - 8y = 11 gives a y value of -4.  so your solution is (3, -4) or B above.

A tub filled with 50 quarts of water empties at a rate of 2.5 quarts per minute. let w = quarts of water left in the tub and t =
Sholpan [36]

This is a linear relationship. The slope-intercept form of the linear equation is:

y=mx+c

Where,

  • m is the rate of change (positive if increasing rate and negative if decreasing rate)
  • c is the y intercept, or the initial value

<u><em>Rate of change is 2.5 quarts per minute (it is decreasing so m is -2.5)</em></u>

<u><em>Initial value is 50 quarts, so c is 50.</em></u>

Plugging in the values we get y=-2.5x+50.


Changing variables to w instead of y and t instead of x, gives us,

w=50-2.5t. Where w is warts of water left in the tub and t is the time in minutes.


There is no viable solution when t=30 because at t=20, w=0 (0=50-2.5(20)). It means after 20 minutes, there is no water left. So t=30 minutes doesn't make sense.


ANSWER:

Modelling equation: w=50-2.5t

When t=30, there is no VIABLE solution

Can a zero slope be a function
steposvetlana [31]

Answer:

A zero slope means there is no change in the y -coordinates as the x -coordinates change, so this is a horizontal line.
