Answer:

b. -33

Step-by-step explanation:

The question is about finding the determinant of a 2×2 matrix

General formula; when given matrix A =[  b  c ]

                                                                  [ d   e]

the determinant of A = (e×b)-(c×d)

Evaluate

(3  -3)

(-5  -6)  = (-6×3) - ( -5×-3)

            = (-18)- ( 15) = -33

What is the perimeter of a rectangle which measures 300m long and 78m 60 cm wide?​
Paraphin [41]

Answer:

75720cm or 757.2m

Step-by-step explanation:

300m = 30000cm

78m & 60cm=7860cm

perimeter of rectangle = 2(length) + 2(width)

2(30000) + 2(7860) = 75720cm or 757.2m

Draw a picture to show how 2/3 of jakes pizza can be equal to 3/6 of a pizza from als
Harlamova29_29 [7]
2/3 of a pizza is more than half of the pizza.


3/6 = 1/2, so 3/6 of a pizza is exactly half of the pizza.


Given that two pizzas are of different sizes you need to calculate the areas of each pizza and compare them.


Assumming that the two pizzas are circular, you can calculate the area of each pizza from the formula of the area for a circle:


Area of a circle = π * (radius)^2.



Call r the radius of Jake's pizza and R the radius of Al's pizza. Then:


Area of Jake's pizza = π (r^2) and 2/3 of that is: 2π(r^2) / 3.


Area of Al's pizza = π (R^2) and 1/2 of that is π(R^2)/2


So, what you have to do is to use the radius of each pizza, calculate above formulaes and verify whether the results are the same or not.
