Answer:
just follow the rules
Step-by-step explanation:
Cramer's rule applies to the case where the coefficient determinant is nonzero. ... A simple example where all determinants vanish (equal zero) but the system is still incompatible is the 3×3 system x+y+z=1, x+y+z=2, x+y+z=3.
Write the system as a matrix equation. ...
Create the inverse of the coefficient matrix out of the matrix equation. ...
Multiply the inverse of the coefficient matrix in the front on both sides of the equation. ...
Cancel the matrix on the left and multiply the matrices on the right.
What is the area of the actual bathroom in square feet? Round your answer to the nearest whole number.
7 ft2
19 ft2
12 ft2
140 ft2
The scale of 1 to 20 , means for every 1 inch on the drawing the actual size would be 20 inches.
The length is labeled 2 inches, so the actual length would be 2 *20 = 40 inches.
The width is labeled as 3.5 inches, the actual length would be 3.5 x 20 = 70 inches.
Now convert the inches to feet by dividing each length by 12:
40 inches / 12 = 3.33 feet.
70 inches / 12 = 5.83 feet.
Multiply them together for total area:
3.33 x 5.83 = 19.4 feet^2
Rounded to the nearest whole number = 19ft^2
The area of the actual bathroom in square feet is
The scale of 1 to 20 reprsent that for every 1 inch on the drawing the actual size should be 20 inches.
The length is labeled 2 inches,
so the actual length is
= 2 (20)
= 40 inches.
Now
The width is labeled as 3.5 inches,
So, the actual length
= 3.5 (20)
= 70 inches.
Now convert the inches to feet by dividing each length by 12:
Now Multiply them together for total area:
= 3.33 (5.83)

How much will Brian have after 3 years?
Give your answer to the nearest penny where appropriate.
Answer:
£1690
Step-by-step explanation:
Amount invested by Brian = £1300
rate of simple interest = 10%
To find money Brian will have after three years
He will have amount invested in bank and interest earned in three years from that amount.
Simple interest for any principal amount p is given by
SI = P*R * T /100
where SI is simple interest earned
T is time period for which simple interest is earned
R is rate of interest
Substituting value of P , R and T we have
SI = 1300*10* 3 /100 = 390
Therefor interest earned will be £390
Total money with Brian after three years = principal amount invested + interest earned in 3 years
= £1300 + £390 = £1690
