Answer:

Step-by-step explanation:

CI = 624 x 1.05 ^3 =722.358 for whole investment   722.36-624 =98.36 for interest only

or for interest only do 624 x .05^3 = 98.36

Standard interest is done like this

year 1 = 624 x 1.05 = 655.20

655.20-624 = 31.20

year 2 = 655.20 + 31.20 = 686.40

year 3 = 686.40 + 31.20 = 717.60

total interest = 717.60-624 = 93.60

So standard interest is the method you have done they may be asking for either compound interest which is the first one or asking for whole investment which means you need to also add 624 at end for Standard interest.

if you need CI interest do the top one.

Find all possible values of the digits Y, E, A, R if YYYY - EEE + AA - R = 1234, and different letters represent different digit
schepotkina [342]

Answer:

Y:  2

E:  9

A:  1

R:  0

Step-by-step explanation:

If we used the value  Y = 2,   E = 9  , A = 1  and R = 0

in the given equation i.e

YYYY - EEE + AA - R = 1234.

From LHS,

Putting the value of Y,E, A and R in the given question we get

2222-999+11-0\\=\ 1223\ + 11\\=\ 1234

=RHS

Therefore\  the\  value\  of \   Y, E, A, R\  is\  2\ , \  9 , \ 1\   and\  0

aron lei is making identical balloon arrangements for a party. He has 32 maroon balloons and 24 white balloons, he wants each ar
alexandr402 [8]

Answer:

The greatest number of arrangements that he can make if every balloon is used is 8.

Step-by-step explanation:

The greatest number of arrangements will be the greatest common factor between 24 and 32.

GCF of 24 and 32:

We keep factoring both numbers by prime factors, while they can both be divided by the same number. So

24 - 32|2

12 - 16|2

6 - 8|2

3 - 4

There is no factor for which we can divide both 3 and 4. So the GCF is 2*2*2 = 8.

This means that the greatest number of arrangements that he can make if every balloon is used is 8.

3. The diameter of the large bird bath is 6 feet. The CGJ girls plan to put bird perches around the outside edge of the bath suc
laila [671]
First we need to determine the circumference of the bath.

Circumference = Diameter X pi 

6(pi) = 18.84 feet

and the girls want to put perches that are at least 3 feet between each other so you can just divide the circumference by 3 

18.84 / 3 = 6.28 so 6

If you don't understand the concept then think of it like this, if you have in total 18.84 feet and you want to place something down every 3 feet then start subtracting 3 from your total till you can't add anymore perches. 

18 - 3 = 15
15 - 3 = 12
12 - 3 = 9
9 - 3 = 6
6 - 3 = 3
3 - 3 = 0

We subtracted 3, SIX times so we added 6 perches
