1) 3 liters left

2) 9 liters of blue paint

Step-by-step explanation:

1) 1/5 * 15 = 3

2) 3 liters of blue paint for each 8 liters.

24/8 * 3 = 9

1.

The amount of flour used is :

= 4/5 × 15 kg

= 12 kg

The amount of flour left is :

= 15 kg - 12 kg

= 3 kg

2.

5 : 3 = Red : Blue

The amound of blue paint :

= 3 : (3 + 5) × 24 liters

= 3 : 8 × 24 liters

= 9 liters

So, the litres of blue paint did he use is 9 liters

Answer:

Hey, so it's actually pretty simple I'll try my best to explain it properly!

Step-by-step explanation:

So for the first blue circle the line that goes to the middle that's the radius. And to solve the area you need to know the radius. The formula to solve the area is A = [tex]\pi[/tex] [tex]r^{2}[/tex] so what we would do its 3.14 times 6 times 6 or 3.14 times 36 which would give us the area! Now for circumference, the equation for that is C = 2[tex]\pi r^{2}[/tex] which would look like 2 times 3.14 times 6 times 6 or 2 times 3.14 times 36 and that would give you the circumference.

Answer: The water level drops each hour by 0.1472 inches/hour.

Step-by-step explanation:

We are given that Between 9 AM and 6:10 AM the water level in a swimming pool decreased by 5/12 inches assuming that the water level decreased at a constant rate.

Firstly, we will find the number of hours between 6:10 AM and 9 AM, that is;

Number of hours = From 6:10 AM and 9 AM, there are 2 hours and 50 minutes

So, Number of hours =  = 2.833 hours

Also, the water level in a swimming pool decreased by =  = 0.417 inches

Now, to find how much did the water level drop each hour, we will divide the amount of water level in a swimming pool decreased by the time interval given, that is;

=

= 0.1472 inches/hour.

This means that the water level drops each hour by 0.1472 inches/hour.

0.1472 as a fraction is 92/625

Answer:

1.5 sec by meters

Step-by-step explanation:

90 meters/60 sec=1.5

Darrel walks at a unit rate of 1.5 m/sec.

Speed is defined as the rate of change of position in unit time.

Mathematically,

Speed = Distance/Time

Now it is given that,

Distance in walk by Darrell = 90 meters

Time taken by Darell to walk 90 meters = 60 seconds

Therefore Speed i.e unit rate of walk is given as,

Unit rate of walk = Distance in walk by Darrell / Time taken by Darell to walk 90 meters

⇒ Unit rate of walk = 90/60 m/sec

⇒ Unit rate of walk = 3/2 m/sec

⇒ Unit rate of walk = 1.5 m/sec

Thus, Darrel walk at a unit rate of 1.5 m/sec.

Answer:

9.75, 2, and 56.25

Step-by-step explanation:

Since it's 4 movie tickets, 2 popcorns (which are $6.25),

4(9.75) + 2(6.25 -> Popcorn) + 4.75

= 39 + 12.5 + 4.75

= 39 + 17.25

= $56.25

As for the total cost,

4 * 9.75 = 39

2 * 6.25 = 12.5

1 * 4.75 = 4.75

Answer:

a) 1/2

b) 250

Step-by-step explanation:

The start of the question doesn't matter entirely, although is interesting to read. What we are trying to do is find the value for [tex]p[/tex] such that [tex]1000p(1-p)[/tex] is maximized. Once we have that [tex]p[/tex], we can easily find the answer to part b.

Finding the value that maximizes [tex]1000p(1-p)[/tex] is the same as finding the value that maximizes [tex]p(1-p)[/tex], just on a smaller scale. So, we really want to maximize [tex]p(1-p)[/tex]. To do this, we will do a trick called completing the square.

[tex]p(1-p)=p-p^2=-p^2+p=-(p^2-p)=-(p^2-p+1/4)-(-1/4)=-(p-1/2)^2+1/4[/tex].

Because there is a negative sign in front of the big squared term, combined with the fact that a square is always positive, means we need to find the value of [tex]p[/tex] such that the inner part of the square term is equal to [tex]0[/tex].

[tex]p-1/2=0\\p=1/2[/tex].

So, the answer to part a is [tex]\boxed{1/2}[/tex].

We can then plug [tex]1/2[/tex] into the equation for p to find the answer to part b.

[tex]1000(1/2)(1-1/2)=1000(1/2)(1/2)=1000*1/4=250[/tex].

So, the answer to part b is [tex]\boxed{250}[/tex].

And we're done!
