Isabella has twice as much money invested at 4% as she has invested at 3%, and she has $500 more invested at 5% than she has at

adell [148]

Invested at 3% = x
invested at 4% = 2x
invested at 5% = x+500

0.03x + 0.04(2x) + 0.05(x+500) = 2025
0.03x + 0.08x +0.05x +25 = 2025
0.16x = 2000
x= 12,500
4% = 2x = 12,500 * 2 = $25,000

kicyunya [14]

Answer:

Solution,

<N=180-53-44

 =83

<h3>Apply sines rule,</h3>

 $\frac{lm}{sin \: 83} = \frac{14}{sin44} \\ lm = \frac{14 \: sin \: 83}{sin \: 44} \\ lm = 20$ 

hope this helps..

Good luck on your assignment..

Question: A square with sides of length 5 is positioned inside a square with sides of length 7. What is the total area between t

Sergio [31]

Answer:

The total area between the squares is of 24 units squared.

Step-by-step explanation:

Area of a square:

The area of a square of side length l is given by:

$A = l^2$

Area between figures:

The area between two figures is the area of the larger figure subtracted by the area of the smaller figure.

Larger square:

Square with side of length 7. So

$A_l = 7^2 = 49$

Smaller square:

Square with side of length 5. So

$A_s = 5^2 = 25$

What is the total area between the squares? 

$T = A_l - A_s = 49 - 25 = 24$

The total area between the squares is of 24 units squared.

when coloring in a grid to show a fraction, what does 3/10 look like when the grid represents a whole

Katarina [22]

Answer:

3 of 10 grid squares making up the whole will be colored.

Step-by-step explanation:

1/10 is one of ten equal parts. 3/10 is three of those ten equal parts. Essentially, the fraction 3/10 means "three out of ten".

_____

If the whole is divided into more than 10 parts, 3/10 will be 3 out of every 10. So if there are 20 parts, for example (2 tens), the 3/10 will be 6 of those parts (3 of each of the two tens).
