4. A 16-piece orchestra wants to choose one
pishuonlain [190]

Answer:

1/12

Step-by-step explanation:

subtract the four soloists who can't be chosen from the total musicians

16-4=12

Itzhak is one person out of 12 who could be chosen to speak

Also the question is annoying because nobody calls an orchestra with 16 people a "16 piece orchestra"

If A and B are matrices and AB = I, which of the following represents the value of B?
Ratling [72]
If the product of 2 matrices are I this means that B is inverse matrix of A.
the matrix A has been given 
if we put symbols for the numbers in matrix A as shown below;
\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right] 

we need to first find the determinant (D)
D = ad - bc
where a = -1 , b = 4, c = -3 and d = 8
substituting these values 
D = -1x8 - (4x-3)
   = -8 +  12 = 4 
to find the inverse we need to exchange a and d and then multiply both b and c by -1
\left[\begin{array}{ccc}8&-4\\3&-1\\\end{array}\right]
and then have to divide all the terms in matrix by determinant (4)
\left[\begin{array}{ccc} \frac{8}{4} & \frac{-4}{4} \\  \frac{3}{4} & \frac{-1}{4} \\\end{array}\right]
the simplified inverse matrix B is;
\left[\begin{array}{ccc} 2 & -1 \\ \frac{3}{4} & \frac{-1}{4} \\\end{array}\right]

Angel uses 1/8 cup of sugar for 1/3 of a recipe. How much sugar is needed if Angel makes the entire recipe twice?
umka2103 [35]

Answer:

3/4 cups of sugar

Step-by-step explanation:

So we know that 1/8 cup of sugar is for 1/3 OF a recipe.

So if we want the full recipe we jsut have to multiply 1/8 by 3 since its only worth 1/3 of the recipe.

You’ll get 3/8 cups of sugar for a whole recipe. The question asks for 2 full recipes and since we already know it takes 3/8 cups for one we can multiply that by 2 to find the amount of sugar needed for 2 full recipes.

You’d get 6/8 cups of sugar.

Simplified: 3/4
