Answer:
17 days and a half.
Step-by-step explanation:
First, we can find how much money he makes per day cutting lawns. This can be found with the equation:
40 x 5 = 200
He makes $200 a day cutting lawns.
Now we can divide his goal money ($3500) by his daily rate ($200) to get the number of days it will take to reach his goal.
3500 ÷ 200 = 17.5
It will take him 17.5 days to reach his goal.
To sum up, we only have the length of one side.
We need to find the width of the same side. -
20.5 x 20.5 = 420.25
To get the surface area, we multiply by six.
<u>Why?</u> There are six sides on a cube.
420.25 x 6 = 2521.5
Answer: 2521.5 cm
Answer:
Step-by-step explanation:
Piece of land:
Length = l = 10 m & width = w = 8 m
Area of land = l*w
= 10 * 8
= 80 square meter.
Flower bed:
Side = 2 m
Area of one square flower bed = side * side = 2 *2 = 4 square meter
Area of 5 flower bed = 5 *4 = 20 sq.m
Area of the remaining land = Area of piece of land - area of 5 flower bed
= 80 - 20
= 60 sq. m

Answer:
Step-by-step explanation:
- The product of two matrices
and 
equals a matrix 
, where the first element of the subscript represents the amount of files of the matrix and the second element represents the amount of columns of the matrix. - Then, in this case
, therefore, its product will result a matrix 
. - Because C matrix is going to have an only file and three columns, we now have to find the values of the elements in each column, based on the elements of A and B.
- Commonly, to obtain the values of the resulting matrix, we just have to multiply each file of the first matrix by each column of the second matrix and sum, as follows:
- Finally, C matrix is
