The depth (inches) of water that accumulates in the spring soil from melted snow can be determined by dividing the cumulative wi

Aleksandr-060686 [28]

Answer:

72 inches

Step-by-step explanation:

Lets say d is the depth of the water in the soil, and s is the cumulative snowfall.

d = s / 12

If d = 6:

6 = s / 12

s = 72

A cumulative snowfall of 72 inches will melt into 6 inches of accumulated water in the spring soil.

1/3 x + 1 = 5/6 x - 3

mr Goodwill [35]

Answer:

x=8

Step-by-step explanation:

Step 1: Subtract 5/6x from both sides.

1/3x+1−5/6x=5/6x−3−5/6x

−1/2x+1=−3

Step 2: Subtract 1 from both sides.

−1/2x+1−1=−3−1

−1/2x=−4

Step 3: Multiply both sides by 2/(-1).

(2/−1)*(−1/2x)=(2/−1)*(−4)

x=8

Find the area of a triangle formed by placing the vectors [3, 6] and [7, 1] tail-to-tail.

Usimov [2.4K]

Answer:

a. $A=10u^{2}$

b. View graph

c. 6.40u

Step-by-step explanation:

knowing that the triangle area is equal to base by heigh between two, then:

$A=\frac{bh}{2}=\frac{5*4}{2}=10u^{2}$

The length of the longest altitude of your triangle is:

$c^{2}=a^{2}+b^{2}=5^{2}+4^{2}=25+16=41\\ c=\sqrt{41}=6.40u$

finally it can be seen that the position of the triangle does not matter, as long as the base and heigh are maintained, the area of the triangle will be the same
