You can only buy 1 CD using $12 because $12 minus $8 is $4 and $4 is not enough for another CD.

You can only buy 1 Cd because 1 cd is 8 dollars, and 8 goes only once into 12. You keep the remaining.

mat deposited $2,000.00 in the bank. if the rate of simple interest was 10%, what was the amount of money mat had in the bank af

Mekhanik [1.2K]

Principal amount of money deposited by Mat in the bank = $2000
Rate of simple interest given by the bank = 10%
Number of years for which the money is kept in the bank = 5 years
As no money was withdrawn from the account, so
Amount after 5 years = Principal [1 + (Rate * Time)]
      = 2000 [ 1 + (10/100) * 5]
      = 2000 [ 1 + (1/2)]
   = 2000 * (3/2)
   = 1000 * 3
   = 3000 dollars
So the amount of money made by Mat after 5 years will be $3000.00

What is the surface area of this triangular prism? The base of each triangle is 42 m and the height of the triangular base is 20

shutvik [7]

<u>Given</u>:

The base of each triangular base is 42 m.

The height of each triangular base is 20 m.

The sides of the triangle are 29 m each.

The height of the triangular prism is 16 m.

We need to determine the surface area of the triangular prism.

<u>Surface area of the triangular prism:</u>

The surface area of the triangular prism can be determined using the formula,

$SA=bh+(s_1+s_2+s_3)H$

where b is the base of the triangle,

h is the height of the triangle,

s₁, s₂ and s₃ are sides of the triangle and

H is the height of the prism.

Substituting the values, we get;

$SA=(42)(20)+(42+29+29)(16)$

$SA=840+(100)(16)$

$SA=840+1600$

$SA=2440$

Thus, the surface area of the triangular prism is 2440 m²

What is the solution to the system of equations? (You can either do the substitution or elimination method) x - 2y = 19 x + 3y =

masha68 [24]

Answer:

D. (17,-1)

Step-by-step explanation:

We'll start by canceling out x. To do so, multiple the first equation by -1

-1( x - 2y)=( 19 )(-1)

This gives us:

-x +2y = -19

x + 3y = 14

Add the equations together:

→ 5y = -15

→ y = -1

Plug in y = -1 into an equation:

→ x + 3(-1) = 14

→ x - 3 = 14

→ x = 17

(17,-1)

Hope this helps!
