Answer:

The formula that is used to calculate the surface area of a triangular prism is, Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area) = (S1 + S2+ S3)L + bh; where 'b' is the bottom edge of the base triangle, 'h' is the height of the base triangle, L is the length of the prism and S1, S2 and S3 are the edges of the base triangle.

Answer:

3 and 6

Step-by-step explanation:

IQR = Q3-Q1=96-62=34

Lower Outlier = Q1 - 1.5*IQR = 62 - 1.5*34 = 11

Any Value under 11 is Considered as Outlier

Then 3 and 6 are Outliers

Upper Outlier = Q3 + 1.5*IQR = 96 + 1.5*34 = 147

Any Value Above 147 is Considered as Outlier

There is no Value above 147

The Only Outliers are 3 and 6

Area of a regular polygon formulas

Step-by-step explanation:

area = n * a * ri / 2 , having ri - incircle radius (it's also an apothem - a line segment from the center to the midpoint of one of its sides)

area = perimeter * ri / 2 , given ri and polygon perimeter.

area = n * (ri)² * tan(π/n) , given ri.

The due date of the promissory note is May 24th 2013.

Data;

To calculate the due date of the note, we can use the formula of future value of the note.

[tex]FV = PV (1 + \frac{r}{n})^d\\ 3970 = 3600 (1 + \frac{9.6}{12})^d\\3970 = 3600(1+0.008)^d\\\frac{3970}{3600} =(1.008)^n[/tex]

Let's take the natural log of both sides

[tex](1.008)^n = (\frac{3970}{3600})\\ n\ln(1.008) = \ln(\frac{397}{360})\\ n = 12.28[/tex]

This is approximately 12 months and 9 days.

The due date of the promissory note is May 24th 2013.

Answer: C: Yes, the Pythagorean Theorem works out to be equal.

Step-by-step explanation:

to test if a triangle is right angled or not, just use the Pythagorean Theorem:

a²+b²=c², where a and b are the two shorter sides of the triangle, and c is the longest side.

plugging this in:

54²+72² ?= 90²

2916 + 5184 ?= 8100

8100 = 8100

Yes! Its correct, so we know that this triangle is a right triangle. the justification is C: Yes, the Pythagorean Theorem works out to be equal.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The sides of a triangle QRS are;

⇒ QR=10X - 6,

⇒ RS = 6X - 15,

⇒ QS = X + 24,

Now,

We know that;

The sum of two sides of a triangle is always greater than the third side.

So, We can formulate;

⇒ 10X - 6 < (6X - 15) + (X + 24)

⇒ 10X - 6 < 7X + 9

⇒ 10X - 7X < 9 + 6

⇒ 3X < 15

⇒ X < 5

Thus, The range of the possible values for X will be;

⇒ X < 5

Answer:

Step-by-step explanation:

find area of circle then subtract

Answer:

3.9 in²

Step-by-step explanation:

The shape is constructed of 2 semicircles (with diameter of 6 in) inside a square.  Therefore, to calculate the yellow region, subtract the area of the semicircles (which form a circle) from the area of the square, then halve the answer.

Area of a square = [tex]x^2[/tex]  ([tex]x[/tex] is the length of one side)

Given:

⇒ area of the square = 6² = 36 in ²

Area of a circle = [tex]\pi r^2[/tex]

Diameter of a circle = 2r

(where r is the radius)

Given:

⇒ area of the circle = [tex]\pi[/tex] × 3² = 9[tex]\pi[/tex] in²

Area of yellow region = (area of square - area of circle) ÷ 2

                                    = (36 - 9[tex]\pi[/tex]) ÷ 2

                                    = 3.9 in² (nearest tenth)

Answer:

p = 1.25x + 70

Step-by-step explanation:

We know she makes $70 each day and we know she makes $1.25 for each computer she sells.

With that we can add it into an equation because we can add 70 + 1.25, but the amount for each computer she sells in unknown so we give it an x which makes it 1.25x.

So, we do 1.25x + 70, but the amount total is missing so that is our p.

This finally completes our equation, p = 1.25x + 70 or  1.25x + 70 = p

Answer:

Step-by-step explanation:

Two distinct lines will always have a point of intersection, provided they are not parallel. That is, the system of equations {x +y = 1, y = mx} will have a unique solution as long as m ≠ -1.

The solution to the system can be found by substitution:

  x +mx = 1

  x(1 +m) = 1 . . . . factor out x

  x = 1/(1+m) . . . . . divide by the coefficient of x; we must have m ≠ -1

  y = m/(1+m) . . . . find the y-coordinate of the solution

The point of intersection is (1/(1+m), m/(1+m)).

__

The above solution is undefined when the denominator is zero: m = -1. There is no solution for m = -1.

Answer:

y=(-1/9)x-(10/3)

Step-by-step explanation:

Since the line is perpendicular to y=9x-5, the slope of that line would be the opposite of the reciprocal of the original slope value. In this case, the slope of the line would be -1/9. So we have y=(-1/9)x+? Since we know a point, (-3, -3), we can input this back into our original equation and we have: -3=(1/3)+? We simplify and we have ?=-10/3. Therefore the final equation of the line that is perpendicular to that line and passes through the point (-3,-3) is y=(-1/9)x-(10/3).
