$400 interest is earned on a principal of $2,000 at a simple interest rate of 59

Mathematics
1 answer:
Charra [1.4K]3 years ago
6 0

Answer:

6.779 years if the interest rate is in dollars.

Step-by-step explanation:

If its 59 percent, it would be well less than a year.

However, if not, divide 400 by 59.

If so, multiply 2000 by .59 to get the per year interest,

then, divide 400 by 1180 to get the answer of 0.33898

53 - 9y = 1<br> -7.2 + 2y = -5
telo118 [61]

Answer:

1.1, -5

Step-by-step explanation:

53 - 9y = 1

from equation i

53-9y = 1

-9y= 1-53 = -52

y = -52/-9= 52/9 = 5⁷/₉

-7.2 + 2y = -5

add 7.2 to both sides

2y= -5+7.2 = 2.2

y= 2.2/2 = 1.1

Which ordered pair is a solution to the system of linear equations?
enyata [817]
2x + 3y = 6.....multiply by 3
-3x + 5y = 10...multiply by 2
-----------------
6x + 9y = 18 (result of multiplying by 3)
-6x + 10y = 20 (result of multiplying by 2)
-----------------add
19y = 38
y = 38/19
y = 2

2x + 3y = 6
2x + 3(2) = 6
2x + 6 = 6
2x = 6 - 6
2x = 0
x = 0

solution is : (0,2)

Given a cube with a volume of 27cm3, what is the volume of a square pyramid?
VashaNatasha [74]

First from the information we have, we see that the volume of the cube is 27cm3. So what are the dimensions of its length, width and height? This information will help us to determine the dimensions of the square pyramid.


Volume of a cube is found from the formula  V = a3


Where V is volume, and a is the length of one side.


We expand this equation to be:


V= a * a * a


Since all sides of a cube are equal, then this equation will be:


27 = 3 * 3 * 3


Now we know the length width and height of the cube.


Volume of a  square pyramid is given by the formula V =1/3ah


Where V is the volume, a is the area of the base of the pyramid, h is the height of the pyramid.


Since it fits perfectly into the cube, then its dimensions are the same as the cube, so:


Area of the base is Length * Width so:


a = 3 * 3 = 9


and height:


h = 3


Now therefore:


 V =  1/3 * 9 * 3


V = 1/3 * 27


V = 27/3


V = 9 cm3
