Answer:

  • area = 14 square units
  • perimeter = 19.1 units

Step-by-step explanation:

The base of the triangle extends from x=2 to x=6, a distance of 4 units.

The height of the triangle is 9 - 2 = 7 units.

Then the area is ...

  A = (1/2)(4 units)(7 units) = 14 units^2

__

The length of the hypotenuse is given by the Pythagorean theorem.

  h^2 = 4^2 +7^2 = 16 +49 = 65

  h = √65 ≈ 8.1

The perimeter is the sum of the side lengths:

  P = 4 + 7 + 8.1 = 19.1 . . . units

The sum of the measures of angle M and R are complemetary. The measure of the angle M is (5×+90). The measre of angle R is 55. W
Alexandra [31]

Answer:

The value of x is - 11  

Step-by-step explanation:

Given as :

∠ M = (5x +90) °

∠ R = 55°

The sum of measure of angle M and R are complementary

Complementary Angle are those when sum of two angle equal to 90°

∵ Angle M and R are complementary in nature

∴ ∠ M + ∠ R =  90°

Or, (5x +90) ° + 55°  =  90°

Or, 5x = 90° - 90°  - 55°  

Or, 5x = - 55°

∴      x = - \frac{55}{5} = - 11

Hence the value of x is - 11        Answer

Which is the solution set of the compound inequality 3.5x-10>-3and 8x-9<39
dimulka [17.4K]

So to solve for an inequality, you must isolate the variable, in this case x, to one side.

Starting with 3.5x - 10 > -3, firstly add both sides by 10:

3.5x > 7

Next, divide both sides by 3.5 and your first half is:

x > 2

Next with 8x - 9 < 39, firstly add both sides by 9:

8x < 48

Next, divide both sides by 8 and your second half is:

x < 6

<u>Putting it together, your final answer is x > 2 and x < 6 or 2 < x < 6.</u>

Please help me again this due midnight
pishuonlain [190]

Answer:

A) 0.5 g/cm³

Step-by-step explanation:

To find volume, you must multiply length × width × height

So it would be 3 × 2 × 4

3 × 2 × 4 = 24

Volume = 24

Plug in both numbers into the equation for Density

12 ÷ 24 = 0.5

The density will be 0.5 g/cm³
