The answer is 0.368

Step 1. Our output value is 80.

Step 2. We need to represent the unknown value with x.

Step 3. From step 1, 80 = 100

Step 4 and Step 5: Similarity x = 0.46% and do 80 = 100% equals to x = 0.46%

Step 6 and step 7: 80/x = 100%/0.46%

Do it again but do it reciprocal of both sides. X/80 = 0.46/100

X=0.368 is the answer

The answer would be 0.368 because you would have to multiply 0.46% and 80 to get your answer, 0.368.

​Together, teammates Pedro and Ricky got 2676 base hits last season. Pedro had 276 more hits than Ricky. How many hits did each
Alborosie
Let's use the variable r to represent ricky's base hits:
Ricky is r
Pedro is r + 276
So:
r + r + 276 = 2676
2r = 2400
r= 1200
Ricky hit 1200 base hits, and Pedro hit 1476 base hits.

Evaluate the determinant of the matrix.<br> -4 5 6<br> 0 4 4<br> -2 -5 4<br> I need the work plz
FromTheMoon [43]

Answer:

-136

Step-by-step explanation:

We have to find the determinant of the following matrix:

\left[\begin{array}{ccc}-4&5&6\\0&4&4\\-2&-5&4\end{array}\right]

We can find the determinant by expanding via 1st column. i.e. by taking each element of 1st column and multiplying it by its co-factor matrix as shown below:

det \left[\begin{array}{ccc}-4&5&6\\0&4&4\\-2&-5&4\end{array}\right]

= (-4 \times det \left[\begin{array}{cc}4&4\\-5&4\end{array}\right]) - (0 \times (-4 \times det \left[\begin{array}{cc}5&6\\-5&4\end{array}\right]))+ ((-2) \times det\left[\begin{array}{cc}5&6\\4&4\end{array}\right])\\\\ =-4 \times (16 + 20)-(0)+(-2 \times 20-24)\\\\ =-4(36)+(-2(-4))\\\\ =-144+8\\\\ =-136

The notation det() stands for determinant of the matrix.

Therefore, the determinant of the given matrix is -136
