Answer:
The three most important are to bear the load of the building, anchor it against natural forces such as earthquakes, and to isolate it from ground moisture. The relative importance of these functions changes with the type of land underneath the building and the building design
Answer:
solution: (3, 5)
Step-by-step explanation:
Solve this system of equations
{2x + y = 11
{5x - y = 10
add the equations to use elimination method.
2x + 5x + y - y = 11 + 10;
7x = 21
x = 21/7 = 3
x = 3
y = 11 - 2x = 11 - 2*3 = 11 - 6 = 5
Answer:
y=4x+1
Step-by-step explanation:
1. 4x-y=2
-y=-4x+2 divide both sides by -1
y=4x-2
2. y-y1=m(x-x1)
y-(-3)=4(x-(-1))
y+3=4x+4
y=4x+4-3
y=4x+1
Parallel lines have the same, so the equation we are making should have the slope of 4.
If r is the cost of roses which he use 5 d is daisies which he used 3 and f is green filler and he used 4 the cost of 75 more is 234
Answer:
sum of the series = 7182
Step-by-step explanation:
This is an arithmetic series. The first term is known as 586 and the last term is known as 212. We are ask to find the sum of the series. The common difference of this sequence is -22 . The difference between the next term and the previous term is -22. Let us find the number of terms.
common difference = 564 - 586 = -22
number of terms = n
nth term = a + (n - 1)d
212 = 586 + (n - 1)-22
212 = 586 - 22n + 22
212 - 586 - 22 = -22n
-396 = -22n
divide both sides by -22
n = -396/-22
n = 18
Using the formula for sum
sum of nth term = n/2(a + l)
where
l = last term
a = first term
n = number of term
sum of nth term = n/2(a + l)
sum of nth term = 18/2(586 + 212)
sum of nth term = 9(798
)
sum of the series = 7182
