Answer:

198.57 cm^2

Step-by-step explanation:

If we join the 2 semi circles, we get a circle.

We can A = pi*r^2

d= 10, r = 5

Area of circle = pi*5^2 ,

= 25*pi

Since diameter= 10 vertically, it should be 10 horizontally too, but it's divided into 2 because of the 2 semi circles.

Thus, width of each semi circle is 5 cm.

Area of rectangle = l *b

Area = (22-10)*10

Area = 12*10

= 120 cm ^2

Total area = 25pi + 120

= 120 + 25(22/7)

= 120 + 78.57

= 198.57

System of Linear Equations entered :

 [1]           -2y-3y+z=-6

 [2]           x+y-z=5

 [3]           7x+8y-6z=31

Equations Simplified or Rearranged :

  [1]    -5y + z = -6

  [2]    y - z + x = 5

  [3]    8y - 6z + 7x = 31

Solve by Substitution :

// Solve equation [2] for the variable  x

 [2]    x = -y + z + 5

// Plug this in for variable  x  in equation [3]

  [3]    8y - 6z + 7•(-y +z +5) = 31

  [3]    y + z = -4

// Solve equation [3] for the variable  z

 [3]    z = -y - 4

// Plug this in for variable  z  in equation [1]

  [1]    -5y + (-y -4) = -6

  [1]    -6y = -2

// Solve equation [1] for the variable  y

  [1]    6y = 2

  [1]    y = 1/3

// By now we know this much :

   y = 1/3

   z = -y-4

   x = -y+z+5

// Use the  y  value to solve for  z

   z = -(1/3)-4 = -13/3

// Use the  y  and  z  values to solve for  x

 x = -(1/3)+(-13/3)+5 = 1/3

Solution :

{y,z,x} = {1/3,-13/3,1/3}

Step-by-step explanation:

By the concept of absolute value, we have:

[tex] | - 9| = 9 \\ \\ | - 15| = 15 \\ \\ |14| - | - 14| \\ = 14 - 14 \\ = 0[/tex]

Step-by-step explanation:

5-(-2)

5+2 (a minus and a minus together gives a plus)

=7

9+ (-2)

9-2

=7 (a plus and a minus gives a minus)

Yes it will give you the same answer as a minus and a minus together gives a plus and a plus and a minus gives a minus

Answer:

9 of 12 children had an apple.

Step-by-step explanation:

First we will divide 12 by 4

12 / 4 = 3

1 / 12 = 3

3 * 3 = 9

9/12 = 3/4

9 of 12 children had an apple.

Answer:

China produced 18% of the world's wheat yield in 2015.

Step-by-step explanation:

To determine the percentage of the world's wheat yield China produced in 2015, we will divide the quantity of wheat China produced by the total quantity of wheat produced globally and then multiply by 100%.

From the question,

Wheat produced globally in 2015 = 734.1 million tons

Wheat produced by China in 2015 = 130.2 million tons

Percentage of the world's wheat yield China produced in 2015 =

(130.2 million tons / 734.1 million tons) × 100%

= 0.17736 × 100%

= 17.736%

= 18% ( to the nearest whole number)

Hence, China produced 18% of the world's wheat yield in 2015.

Answer:

Top right

Step-by-step explanation:

Because it is negative and that is the typical shape for x^4 functions

The graph represents the given function f(x) is attached below

Top right option graph is correct

Given :

The equation of a graph is given by

[tex]f(x)=-2x^4[/tex]

Lets look at the end behavior of the given function f(x)

The leading coefficient is negative  that is -2

The highest exponent is 4 that is the degree is even

When the leading coefficient is negative and degree is even then the graph goes down on both sides  

As x-> ∞, f(x)-> -∞

As x-> -∞, f(x)-> -∞

So , the graph on the top right is correct

Answer:

It is the total cost of housing and plane tickets for four years.

Step-by-step explanation:

Mark's costs for tuition, technology fee, and books are all per semester, s. ($2,600 + $150 + $310)s = $,060s

The cost for housing and plane tickets are a once a year cost. Mark pays these amounts once a year for four years.4($5,600 + $289) = $23,556

Therefore, the constant in the expression is $23,556, and it is the total cost for housing and plane tickets for four years.

Answer:

y = 1/3x + 26/3

Step-by-step explanation:

Original equation: y = -3x + 2

Perpendicular lines have the "opposite reciprocal" slopes of each other, meaning you flip the numbers and reverse the sign.

Slope of original equation: -3

Slope of perpendicular line: 1/3

How: Reciprocal, flip the numbers: -3/1 to -1/3, then reverse sign -1/3 to 1/3

Then you substitute (-2, 8) into the new equation: y = 1/3x + b

*there's b because you don't know the y-intercept yet

Substitute: 8 = 1/3(-2) + b

8 = -2/3 + b

Add 2/3 on both sides

b = 24/3 + 2/3

b = 26/3

*this is the y-intercept

Therefore, the perpendicular equation is: y = 1/3x + 26/3
