Answer:

[B]=2

Step-by-step explanation:

B=\left[\begin{array}{ccc}3x-5&-3+2y\\11-3x&2y-5\end{array}\right]

With x=3 and y=4

B=\left[\begin{array}{ccc}3(3)-5&-3+2(4)\\11-3(3)&2(4)-5\end{array}\right]

B=\left[\begin{array}{ccc}9-5&-3+8\\11-9&8-5\end{array}\right]

B=\left[\begin{array}{ccc}4&5\\2&3\end{array}\right]

solving the determinant of matrix B

[B]=\left[\begin{array}{ccc}4&5\\2&3\end{array}\right]=(4.3-5.2)=(12-10)=2

What is a 15 yard gain 
Alex_Xolod [135]
Are you by any chance referring to football? If you are, it is either a play in which by running or passing the offense moves down the field towards the opponent's endzone 15 yards, or it can be obtained by the defense committing an egregious penalty, such as a facemask, unsportsmanlike conduct, or unnecessary roughness.

rhombus has sides of length 10 cm. and the angle between two adjacent sides is 76 degrees. Find the lengths of the other diagona
lisabon 2012 [21]
Let the length of one of the diagonals be 2x and the other be 2y, then
cos (76/2) = x/10
x = 10 cos 38 = 7.88 cm

sin (76/2) = y/10
y = 10 sin 38 = 6.16 cm

A survey of voters explored the relationship between the ages of voters and wether or not they support building skateboard ramps
Novosadov [1.4K]

Answer:

(a)12%

(b)20%

(c)49%

Step-by-step explanation:

(a)In the age group 58 and above:

  • Number in favor of building the skateboard ramps=6
  • Number opposed to building the skateboard ramps=44
  • Total = 50

Percentage of those in favor = \frac{6}{50}X100 =12\%

(b)In the age group 18-37

  • Number in favor of building the skateboard ramps=40
  • Number opposed to building the skateboard ramps=10
  • Total = 50

Percentage of those opposed to it = \frac{10}{50}X100 =20\%

(c)

  • Total Number of those in favor of building the skateboard ramps=73
  • Total Number opposed to building the skateboard ramps=77
  • Total = 150

Percentage of those in favour = \frac{73}{150}X100 =48.67 \approx 49\%
