The lateral area of the tea bag is the sum of the areas of the four triangles.
LA = 4 x (1/2)bh
Substituting,
LA = 4 x (1/2)(4 cm)(5 cm) = 40 cm²
The surface area is the sum of the lateral area and the area of the base.
SA = LA + BA
SA = 40 cm² + (4 cm)(4 cm) = 56 cm²
Let the three apartments be A, B & C
The rent of A is $x
The rent of B is $y
The rent of C is $z
So x + y + z = 1600 .......(1)
Now
Maintenance of A is 20% of x = 0.20x
Maintenance of B is 20% of y = 0.20y
Maintenance of C is 25% of z = 0.25z
0.20x + 0.20y + 0.25z = 345
Multiplying by 100 we get
20x + 20y + 25 z = 34500
Dividing by 5 we get
4x + 4y + 5z = 6900 .......(2)
Monthly fee of A is 10% of x = 0.10x
Monthly fee of B is 20% of y = 0.20 y
Monthly Fee of C is 10% of z = 0.10z
Now
0.10x + 0.20y + 0.10 z= 1820 - 1600
0.10x + 0.20y + 0.10z = 220
Multiplying by 100 we get
10x + 20y + 10z = 22000
Dividing by 10
x + 2y + z = 2200 ....(3)
Making a Matrix of equation (1), (2) & (3)
is the required matrix
Answer:
24 is the answer...good luck
Answer:
3 gal per 42 miles
Step-by-step explanation:
The question is written weird but...
If the vehicle goes 14 miles per 1 gallon. We are just looking for which answer breaks down to that base.
42÷3=14
3÷3=1
It's just giving a three gallon distance instead of a 1 gallon.
Answer:
Y-Y1=M(x-x1)
that's the formula then fixing in your values we have
y + 5 =2(x-3)
y+5 =2x-6
Crossing over we have
y-2x=-6-5
equation of the line equals
y-2x-11 =0
