The answer to the problem is 44 in^2.

Answer:

Step-by-step explanation:

The given figure is a compound figure with a triangle on top followed by a rectangle below and next below is a trapezium

Hence area of the given figure = area of top triangle +area of middle rectangle+area of bottom trapezium

Area of top triangle= \frac{1}{2} (bh) (b=base h=height)=\frac{1}{2}(4x3)=6

Area of middle rectangle=bh 3x10=30

area of a trapezoid=\frac{1}{2}h(b_1 +b_2) =\frac{1}{2}(5+3)2 =81/2(base+base)h (two bases because one on top, one on bottom) 1/2(5+3)2=8

Total area = 6+30+8 =44 in^2

Veronica has been saving dimes and quarters she has 110 coins in all and the total value is 18.50 how many dimes and quarters do
Lady_Fox [76]

This problem can be solved by the chicken rabbits method or you can just do simple algebra.

I.) Chicken and rabbits method

First assume all 110 coins are dimes and none are quarters.

We will have a total value of 11 dollars

Now for each dime we switch out for a quarter, we adds 15 cents to the total value.

18.50-11=7.50 dollars

There are 750/15=50 group of 15 cents in the 7 dollars and 50 cents.

This also meant that we need to switch out 50 dimes for 50 quarters.

So we have 50 quarters.

That first method is very good and very quick once you get the hang of it, now I'm going to show you the algebraic way to solve this.

Let's say there are x dimes and y quarters.

Set up equation

x+y=110

10x+25y=1850

Now solve multiply first equation by 10

10x+10y=1100

subtract

15y=750

y=50

Now we set the numbers of quarters to y so the answer is 50 quarters.

I personally recommend using algebra whenever you can because the practice is very important and you will eventually get really fast at setting up and solving equations. The first method is faster in this case but the second is more generalize, hope it helps.

What is the square root of 5√2+√18
givi [52]
The square root of 5/2 is 2.236067978. The square root of 18 is 4.242640687. The total of 2.236067978 plus 4.242640687= 6.478708667.
If you rounded up to two decimal points. You will get 6.48. It depends what digit your question is telling you to round up to. 
Hope it helps.
