Answer:

$30341.88

Step-by-step explanation:

Because it says simple interest, use the formula I = Prt.

(I is interest, r is the % rate as a decimal, t is the time)

So, you have to solve the equation,

1755 = P (0.065)(9)

Since 0.065 x 9 = 0.585, the equation can be simplified to

1755 = 0.585P

Then, to get P, you divide both sides by 0.585

P = 1755/0.585 = $30341.88

shutvik [7]

Answer:

<h3>The probability is </h3><h3>\frac{3}{5}</h3>

Step-by-step explanation:

Green marbles = 4

Blue marbles = 6

Yellow marbles = 8

Red marbles = 2

4 + 6 + 8 + 2 = 20 \: marbles

The probability of drawing marble not yellow:

4 + 6 + 2 = 12 \\  \frac{12}{20}  =  \frac{3}{5}

What’s the answer For E
Vika [28.1K]

Answer:

∠E = 146°

Step-by-step explanation:

  • an isosceles triangle has both two equal sides and two equal angles
  • the sum of the interior angles of a triangle is 180°
  • the measure of third angle = the sum of the interior angles - the sum of two angles

E = 180 - (71 + 71) = 146

∠E = 146°

How much fertelizer is needed for a 180 square-foot garden
Fed [463]

Answer:

6 pounds of fertilizers are needed for garden area of 180 square foot.

Step-by-step explanation:

Let 'x' pounds of fertilizers be needed for 180 square foot garden.

Given:

4 pounds of fertilizer needed for an area of 120 square foot.

The area of the garden given is 180 square foot.

Now, as per question:

4 pounds of fertilizer is equivalent to an area of 120 square foot.

Therefore, 'x' pounds of fertilizer is equivalent to an area of 180 square foot.

Applying proportion and cross multiplying method, we get:

x            4

_      =    _

180        120

120x=4 x 180

120x= 720

x = 720

      _

     120

x=6 LBS

Therefore, 6 pounds of fertilizers are needed for garden area of 180 square foot.

Make a Matlab script to make row 2 of matrix A equal to first row of A multiplied by the negative of the first element of row 2
stira [4]

Answer:

X=\begin{Bmatrix}2& 1 &10 \\-3 & 5 & 4\end{Bmatrix}

Step-by-step explanation:

From the question we are told that

Matrix is given as A=\begin{Bmatrix}2 & -1 & 10\\-3 & 8 & 4\end{Bmatrix}

Generally let the change in matrix be given as X

X_1_2 = 2*(-(-1)) + - 1 = 1X_2_2 = -3 * (-(-1))+ 8 = 5

Matlab output

A=[2 -1 10;-3 8 4]\\a=(A(1,1)*-A(1,2))+A(1,2)\\b=(A(2,1)*-A(1,2))+A(2,2)\\X=[A(1,1) a A(1,3); A(2,1) b A(2,3)]\\

Generally the matrix that makes row 2 of matrix A equal to first row of A multiplied by the negative of the first element of row 2 plus the original row is

X=\begin{Bmatrix}2& 1 &10 \\-3 & 5 & 4\end{Bmatrix}
