Find how many quarts of 4​% butterfat milk and 1​% butterfat milk should be mixed to yield 75 quarts of 3​% butterfat milk. The mixture should contain ___ quarts of the 4​% butterfat milk.

Answers

Answer:

50

Step-by-step explanation:

The amount of 4​% butterfat milk  is equal to x quarts , When 1​% butterfat milk  is equal to 75-x. The amount of butterfat in 4​% butterfat milk is x/100*4=0.04x

The amount of butterflat in 1​% butterfat milk is (75-x)/100= 0,75-0.01x

1​The amount of butterflat in 75 quarts of 3​% butterfat milk (our desired mixture) is 75/100*3= 2.25

This quantity (2.25) is the sum of butterfat from  4​% butterfat milk and 1​% butterfat milk(the sum of 0.04x and 0.75-0.01x)

the equation is

0.04x+0.75-0.01x=2.25

0.03x=1.5

x=50

Answer:

A stone is dropped of a 1296-ft-cliff. The height of the stone above the ground is given by the equation h= - 16t^2+1296, where h is the stone’s height in feet, and t is the time in seconds after the stone is dropped. Find the time required for the stone to hit the ground.

Answers

When stone hits the ground, it's height will be zero, and since we're finding the time that's required for the stone to hit the ground, we can set h = 0 and solve for t.

The time required for the stone to hit the ground[tex]v(9)=-288,a(9)=-32[/tex].

What is the equation?

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Here given that,

A stone is dropped of a [tex]1296[/tex]-ft-cliff. The height of the stone above the ground is given by the equation [tex]h=-16t^2+1296[/tex], where [tex]h[/tex] is the stone’s height in feet, and [tex]t[/tex] is the time in seconds after the stone is dropped.

So,

[tex]h=-16t^2+1296\\\\v(t)=\frac{ds}{dt}=-32t+0\\\\=-32t\\\\\\a(t)=\frac{dv}{dt}=-32[/tex]

When [tex]s(t)=0[/tex] now solve it for [tex]t[/tex] so,

[tex]-16t^2+1296=0\\\\t^2=\frac{1296}{16}\\\\t^2=81\\\\t=\sqrt{81}\\\\t=9seconds[/tex]

When [tex]t=9[/tex] so,

[tex]v(9)=-32(9)\\\\v(9)=-288[/tex]

nd

[tex]a(9)=-32[/tex]

Hence, the time required for the stone to hit the ground[tex]v(9)=-288,a(9)=-32[/tex].

Answers

9514 1404 393

Answer:

  after 32 minutes

Step-by-step explanation:

They will both cross the start line together after each has completed a number of full laps in the same time that the other has completed an integer number of full laps. That time will be the least common multiple (LCM) of their lap times, 128 seconds and 120 seconds.

The difference of these times (8 seconds) is also a divisor of both times, so that value is the greatest common divisor (GCD) of the two lap times. The LCM can be figured as ...

  LCM(120, 128) = 120×128/GCD(120, 128)

  LCM = 120×128/8 = 1920 . . . . . seconds

Converting this to minutes, we get ...

  (1920 s)/(60 s/min) = 32 min

They will next cross the start line together after 32 minutes.

Maria reads 3/5 chapters in 5/6 hours whats the unit rate?

Answers

Answer: 18/25 chapters / hour

Step-by-step explanation:

Concept:

Here, we need to know the idea of unit rate.

A unit rate is a rate with 1 in the denominator.

In simple words, the unit rate is something per one thing. For example, when you go to a store, you bought a book that is priced at $10. In actually meaning, it is $10 per book, or $10/book.

Solve:

Given formula

Unit rate = Number of chapters / Hours

Substitute the value into the formula

Unit rate = (3/5) / (5/6)

Convert to multiplication by taking the reciprocal of the divisor

Unit rate = (3/5) · (6/5)

Numerator times numerator / denominator times denominator

Unit rate = (3 × 6) / (5 × 5)

Unit rate = 18 / 25 chapter / hour

Hope this helps!! :)

Please let me know if you have any questions

The unit rate is 18/25 chapters per hour. This means Maria is reading at a rate of 18/25 chapters in one hour.

How to determine the unit rate

To calculate the unit rate, we're trying to find out how much of something (in this case, chapters) happens in a single unit of another thing (time, in hours).

In this scenario, Maria reads 3 out of 5 chapters in 5 out of 6 hours. To find the unit rate, we divide the chapters read (3/5) by the time taken (5/6 hours):

Unit Rate = Chapters Read / Time Taken

= (3/5) / (5/6)

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:

Unit Rate = (3/5) * (6/5)

= (3 * 6) / (5 * 5)

= 18 / 25

So, the unit rate is 18/25 chapters per hour. This means Maria is reading at a rate of 18/25 chapters in one hour.

Which best describes the relationship between the line that passes through the points (6, -1) and (11, 2) and the line that passes through the
points (5-7) and (8-2)?

Answers

Answer:

D. Neither perpendicular nor parallel

Step-by-step explanation:

Let's find the slope (m) of both lines:

✔️Slope (m) of the line that passes through (6, -1) and (11, 2):

Slope (m) = change in y/change in x

Slope (m) = (2 -(-1))/(11 - 6) = 3/5

✔️Slope (m) of the line that passes through (5, -7) and (8, -2)

Slope (m) = change in y/change in x

Slope (m) = (-2 -(-7))/(8 - 5) = 5/3

✅The slope of both lines are not the same, therefore they are not parallel nor same line.

Also, the slope of one is not the negative reciprocal of the other, therefore they are not perpendicular.

The width of a rectangle is one foot more than a third of the length. If the
perimeter is 42 feet, what is the width? What is the length?

Answers

Well, the formula for the perimeter of a rectangle is:
2l + 2w.
So, by plugging in our values of the length and width, we can easily find an answer:
length = L
width = 1 + L ( 1/3 )
2 ( L ) + 2 ( L ( 1/3 + 1 ) = 42
2l + 2/3( L ) + 2 = 42
8/3 ( L ) = 40
L = 40 * 3/8
L = 15
Therefore, the length is 15 and the width is 6.
