Answer:

2,799,360

Step-by-step explanation:

12x18x20x9x8x9=2,799,360

Area of complete figure in 1st way  = 288 cm^2

Area of complete figure in 2nd way = 288cm^2

The area of a rectangle of length =l and breadth =b is length times its breadth . General formula of calculating area of rectangle is  length * breadth

In first case we are dividing the figure horizontally

in which there occur an upper small rectangle of l = 12cm and breadth = 9 cm and a big rectangle of L 20cm and B= 9cm

area of 1st rectangle= l*b = 12 * 9 = 108 cm^2

area of 2nd rectangle = L*B = 20 * 9 = 180 cm ^ 2

area of complete figure in 1st way  = area of 1st rectangle + area of 2nd rectangle

                                       = 108 + 180 = 288 cm^2

In second case we are dividing the figure vertically

in which there occur an  small rectangle of l = 8cm and breadth = 9 cm and a big rectangle of L =18cm and B= 12cm

area of 1st rectangle= l*b = 8 * 9 = 72 cm^2

area of 2nd rectangle = L*B = 18 * 12= 216 cm ^ 2

area of complete figure in 2nd way = area of 1st rectangle + area of 2nd rectangle

                                       = 72 + 216 = 288cm^2

Answer:

  C)  83°

Step-by-step explanation:

The angle marked 97° and b form a linear pair, so are supplementary.

  b = 180° -97° = 83°

Answer:

C .) 83 °

Step-by-step explanation:

Angle b and 99° are on straight line so it's supplementary angles and we know that sum of all angles of supplementary angles is 180 °.

➛ b + 97 ° = 180 °.

subtract each side by 97 °

➛ b + 97° - 97° = 180° - 97°

➛ b = 83°

Answer:

C = 125S + $3750

Step-by-step explanation:

$ 3750  = truck rental;   $125 per ton of sugar transported.  C is the cost;  S is the number of tons transported. The equation relating C to S would be a linear equation like y = mx + b. This equation would be graphed in the first quadrant only. You would start with your y-intercept at (0, 3750). As x increases by 1, your y increases by 125 yielding these points:

(1, 3875)  (2, 4000)  (3, 4125)  etc.

This shows that for each increase by one ton of sugar, the cost goes up $125

Answer:

3) 124

Step-by-step explanation:

a1 = 10

a2 = a1+6 = 10+6 = 16

a3 = a2+6 = a1+6+6 = a1 + 2×6 = 22

a4 = a3+6 = a2+6+6 = a1+6+6+6 = a1 + 3×6 = 28

...

=>

an = an-1 + 6 = a1 + 6(n-1)

=>

a20 = a1 + 6(20-1) = 10 + 6×19 = 10+114 = 124

==================================================

Explanation:

The adjacent complementary angle to that 28 degree angle is 62 degrees because 62+28 = 90.

If the reference angle is the upper acute angle 62 degrees, then the y is the opposite leg and the side 350 is the adjacent leg.

Use the tangent ratio

tan(angle) = opposite/adjacent

tan(62) = y/350

350*tan(62) = y

y = 350*tan(62)

y = 658.254262871217

y = 658.3

[tex]y = -3x + 14[/tex]

Step-by-step explanation:

Required

The equation of line

perpendicular to : [tex]x -3y =9[/tex]

Passes through [tex](3,5)[/tex]

We have:

[tex]x -3y =9[/tex]

Make y the subject

[tex]3y =x - 9[/tex]

Solve for y

[tex]y = \frac{x}{3} - 3[/tex]

Compare the above equation to [tex]y = mx + c[/tex]

[tex]m =\frac{1}{3}[/tex] ---- This represents the slope

Since the line is perpendicular to [tex]x -3y =9[/tex], then its slope is:

[tex]m_2 = -\frac{1}{m}[/tex]

[tex]m_2 = -\frac{1}{1/3}[/tex]

[tex]m_2 =-3[/tex]

The equation of the perpendicular line is:

[tex]y =m_2(x - x_1) + y_1[/tex]

Where:

[tex]m_2 =-3[/tex]

[tex](x_1,y_1) =[/tex] [tex](3,5)[/tex]

So:

[tex]y = -3(x - 3) + 5[/tex]

[tex]y = -3x + 9 + 5[/tex]

[tex]y = -3x + 14[/tex]

Answer:

(10, 15)

Step-by-step explanation:

To get the origin of the equation 2y+3x = 10, we need to get the x and y-intercept of the line.

x-intercept occurs at y = 0

If y = 0

2(0)+3x =10

3x =10

x = 10/3

x = 1.33

y-intercept occurs at x = 0

If x = 0

2y+3(0) =10

2y =10

y = 10/2

y = 5

Hence the coordinate at the origin is (10/3, 5). If this coordinate is dilated by 3, the required coordinate will be at (10/3*3, 5*3) = (10, 15)

Hence the required coordinate is (10, 15)

the graph that he needs to do is a straight line from the origin that passes through (3, 0.75), the correct option is the last one.

He knows the relation:

3 cups of granola ⇒ 0.75 cups of raisins.

Assuming this is a proportional relation of the form:

y = k*x

Where k is a constant.

Then when x = 0, we also have y = 0, so the line also passes through the point (0, 0), which is the origin.

Then the graph that he needs to do is a straight line from the origin that passes through (3, 0.75), the correct option is the last one.
