One week, a cake shop sold 45 pineapple cakes and 62 chocolate cakes on the weekdays and 55 pineapple cakes and 79 chocolate cakes over the weekend. total sales were $3,520 on the weekdays and $4,415 over the weekend. form a linear system representing this data and create a matrix.

the determinant of the matrix for the pineapple cake is:
a. $2850 b. $3420 c. $4350 d. $4625

the determinant of the matrix for the chocolate cake is:
a. $4350 b. $4625 c. $5075 d. $5225

The determinant of the matrix for the pineapple cake is $4350 ⇒  c

The determinant of the matrix for the chocolate cake is $5075 ⇒  c

Step-by-step explanation:

* Look to the attached file

The determinant of the matrix for the pineapple cake is [4,350]. The price of one pineapple cake is [$30].

The determinant of the matrix for the chocolate cake is [5,075]. The price of one chocolate cake is [$35].

Step-by-step explanation: I got this right on Edmentum.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
