Ivan biked 1 whole 2/3 on Monday, 2 wholes 1/3 hours on Tuesday, and 2 wholes 2/3 on Wednesday. What is the total number of hour

GenaCL600 [577]

$1 \frac{2}{3} + 2 \frac{1}{3} + 2 \frac{2}{3} =$

$\frac{3*1+2}{3} + \frac{3*2+1}{3} + \frac{3*2+2}{3} =$

$\frac{3+2}{3} + \frac{6+1}{3} + \frac{6+2}{3} =$

$\frac{5}{3} + \frac{7}{3} + \frac{8}{3} =$

$= \frac{20}{3} h$

In hours:

20 |_3
(2)....6hs
x60'
------
120' |_3
(0)....40'

Answer:
6hs40min

or

 $\frac{20}{3} hs = \frac{20}{3} *60' = \frac{1200}{3} = 400'$

400' = 6*60' = 360' + 40' = 400' (True)
Until

Mr. Bradley purchased 20 trays of flowers. Each tray had 3 dozen flowers. Mr. Bradley's total for all the flowers was 273.60. Al

aev [14]

Answer: Each flower costs $0.38.

Step-by-step explanation:

1 dozen = 12 units

Flowers in each tray = 3 dozen = 3 x 12 = 36

Flowers in 20 trays = 20 x 36 = 720

Price of 20 trays = $ 273.60

Price of each flower = (Price of 20 trays ) ÷ (Flowers in 20 trays)

= 273.60 ÷ 720

= $ 0.38

Hence, each flower costs $0.38.

A long-distance phone company has a monthly fee of $7.95 and charges a rate of $0.05 per minute. Another long-distance company h

d1i1m1o1n [39]

Answer:

100 minutes

Step-by-step explanation:

Let the number of minutes required for the two Billings to be equal be x.

Now we write this in an equation form.

7.95 + 0.05x = 9.95 + 0.03x

0.05x - 0.03x = 9.95 - 7.95

0.02x = 2

x = 2/0.02 = 100 minutes

At the 100th minute, the amount of Billings would be equal

Let A be a 5 × 4 matrix with a pivot in each column. Is A invertible? Why or why not?

erastova [34]

Answer:

Matrix A is not invertible.

Step-by-step explanation:

Invertible matrix are those matrix which are square matrix or non singular matrix.

For any matrix to be invertible, matrix should be non singular i.e. det(x) $\neq$ 0.

But for the question given above we cannot find determinant of matrix A as it is not square matrix. so inverse of given matrix does not exist. so it is not possible to have non trival solutions.
