Interest = Pin = principal * interest rate * number of years

Let interest rate be i, then
600*i*2+150*i*4=90
1200i+600i = 90
i=90/(1200+600)=90/1800=1/20=0.05 or 5%

B) 36 kg in the ratio 1:3:5​
ale4655 [162]

9514 1404 393

Answer:

  4 kg : 12 kg : 20 kg

Step-by-step explanation:

The total number of "ratio units" is 1+3+5 = 9, so each of them represents ...

  (36 kg)/9 = 4 kg

Multiplying the given ratio by 4 kg will show the appropriate division:

  1(4 kg) : 3(4 kg) : 5(4 kg) = 4 kg : 12 kg : 20 kg

Suppose you surveyed a group of students to see how many CDs they owned. The results are displayed in the
Alex17521 [72]

You surveyed 30 students to see how many CDs they owned.

The number of students who owned 5 - 8 CDs was:

= 15

The number of students who owned 9 - 12 CDs was:

= 10

The number of students who owned 13 - 16 CDs was:

= 5

The number of students who owned 17 - 20 CDs was:

= 0

The total number of students surveyed is the sum of the above:

= 15 + 10 + 5 + 0

= 30 students

30 students were surveyed for this study.

Can you help me, please ……..
dedylja [7]

Answer: The correct answer is 44.60

Step-by-step explanation:

Let's find the area of the rectangle first, and then add it with the area of the Circle to find the total area of the whole shape.

We know that the area of a Rectangle is L(Length) x W(Width)

So using the given information, 8 x 4 = 32

So the Area of the Rectangle = 32

Now let's find the area of the given circle,

<em>Area of a Circle: πr2                                     Remember ^ = stands for power</em>

The radius is half of the diameter

The diameter of the circle is 4

4/2 = 2 which is our radius, and now let's replace it in the equation.

= 3.14(r)^2

= 3.14(2)^2

= 3.14(4)

= 12.56 or some may have got 12.57

So now we add all areas together to get the total area,

32+12.57 = 44.57

Now rounding off to the nearest tenths, would give us 44.60

So the area of the figure rounded to the nearest tenth is 44.60

A restaurant critic for a newspaper examines the prices restaurants charge for their meals and discovers that the restaurants th
maksim [4K]

Answer:

When customers wait longer for tables, they are more likely to pay higher prices.

Step-by-step explanation:

Supply/Demand relationships predict that changing one side will influence the other.  If demand exceeds capacity, suppliers can raise prices without risk of losing products sold.  In fact, total income will rise.  The restaurant may raise it's price to the point that supply meets demand.  In this case, the goal of the higher priced meals is to reduce wait times, not meals sold.  If the meals sold are all at a higher price/meal, then income rises and wait times are reduced.  What's not to like, if you own the restaurant?
