  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

3m - n = -10

2m + n = -5

<u>Step 2: Solve for </u><em><u>m</u></em>

<em>Elimination</em>

  1. Combine equations:                    5m = -15
  2. Divide 5 on both sides:               m = -3

<u>Step 3: Solve for </u><em><u>n</u></em>

  1. Define equation:                    3m - n = -10
  2. Substitute in <em>m</em>:                      3(-3) - n = -10
  3. Multiply:                                  -9 - n = -10
  4. Add 9 to both sides:              -n = -1
  5. Divide -1 on both sides:         n = 1

Find the volume of a pyramid with a square base, where the side length of the base is 17 in 17 in and the height of the pyramid
avanturin [10]

Answer:

The volume of the pyramid is 867 inch^3

Step-by-step explanation:

Here in this question, we are interested in calculating the volume of a square based pyramid.

Mathematically, we can use the formula below to calculate the volume V of a square based pyramid.

V = a^2h/3

where a represents the length of the side of the square and h is the height of the pyramid

From the question, the length of the side of the square is 17 in while the height is 9 in

Plugging these values, we have ;

V = (17^2 * 9)/3 = 17^2 * 3 = 867 cubic inch

Sam is framing a closet under a stairway. The stairway is 20 ft 6 in. long, and its angle of elevation is 31º. Find the depth of
leva [86]

Answer:

The depth is 127 inches.

Step-by-step explanation:

The stairway and its depth can be compared to a right angled triangle. Let the depth be represented by d.

But,

12 inches = 1 foot

20 ft 6 in = 20 + (\frac{6}{12} )

               = 20.5 feet

So that applying the appropriate trigonometric function, we have;

Sin θ = \frac{opposite}{hypotenuse}

Sin 31º = \frac{d}{20.5}

d = 20.5 x Sin 31º

   = 20.5 x 0.5150

d = 10.5575

d ≅ 11 feet

Therefore,

d = 10.5575 feet = (10.5575 x 12) inches

  = 126.69 inches

The depth is 127 inches.

Find the diameter of a circle with an area of 226.98 square inches
Thepotemich [5.8K]

We are given here Area of circle as 226.98 square inches.

Formula to find area of circle is given as :

Area of circle = \pi r^{2}

plugging value of A as 226.98 square inches and pi as 3.14, we have

226.98 = (3.14) r^{2}

72.3 =  r^{2}

r=8.5

Now we know that diameter = 2 * radius.

multiplying radius with 2 we have 8.5*2 = 17

Answer : Diameter is 17 inches.
