Look at the graph. Which of the following statements is reflected in the chart? A. Union soldiers were more likely to die of their wounds than Confederate soldiers. B. Soldiers in the Civil War were more likely to die of battle wounds than disease.
  C. Soldiers in the Civil War were more likely to die of disease than wounds in battle. D. Union soldiers were less likely to die of wounds or disease than Confederate soldiers.
I think C or B

Answers

The answer is C. Disease has more deaths than battle wounds so it would be correct. A is kinda close but I don't think it's the answer. D is completely wrong cuz union had more deaths in both sections

Answer:

The answer is C.

If the vertex angle of an isosceles triangle measures 38 degrees what is the measure of one of the base angles

Answers

The measure of one of the base angles is 71°

Step-by-step explanation:

In any isosceles triangle:

  • Two sides are equal in length and the angle between these sides is called the vertex angle
  • The other two angles are equal in measure and they are called the base angles

∵ The triangle is isosceles

∵ The measure of its vertex angle is 38°

- The sum of the measures of the interior angles of a triangle is 180°°

∴ The sum of measures of the base angles = 180 - 38 = 142°

∵ The two base angles are equal in measures

∴ The measure of each base angle = 142 ÷ 2

∴ The measure of each base angle = 71°

The measure of one of the base angles is 71°

What is the length of a side of a cube with volume 729 cm3

Answers

solution:
v = l x w x h
all cube sides are equal:
v = length^3
given v = 729 cm3
length = cube root (729)
length = 9 cm

a and b are vectors such that |a| = √3, |b| = 1, and the angle between them is 5π/6. Using scalar product, find the exact value of |2a + b|.

Answers

Answer:

|2a + b| = 2√(3) + 1

Step-by-step explanation:

|a| = √(3)

|b| = 1

θ = 5π/6

For scalar vectors, A.B = |a|.|b|.cosθ

a

|2a| = 2*√(3) = 2√(3)

|2a + b| = 2√(3) + 1

Since we don't have to find the scalar or dot product, there's no need to use the formula requiring the angle between them

|2a + b| = 2√(3) + 1
