Answer:

38.28

Step-by-step explanation:

ok so one of the sides don't count because the circle is there. so that leaves us with 14 + 14 + 4= 32(my bad)

then the circumference is for half the circle. and when finding the circumference you use radius so 2 cm. 2 x 3.14 x 2 = 12.56

then divide it by 2- 6.28

so that gives us 38.28

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:

x=2

Step-by-step explanation:

Substitute y=0    0=0.5(x-2) 21

multiply the numbers     0=10.5(x-2)        *(21x0.5)

remove the parenthesis     0=10.5x-21

move the variable      -10.5x=-21

divide both sides by   -10.5

solution     x=2

Step-by-step explanation:There are a couple of ways to do this.

This is the straightforward, “follow-your-nose” way. Find a point on each line. (Say, (1,2) on the line with slope 2 and (-1,1) on the line with slope -1. Then the angle in the triangle formed by the origin (0,0) and these other two point is the desired angle. One can find the cosine of angle in the triangle using the Law of Cosines, since the lengths of all of the sides can be found directly from the distance formula and the coordinates of the points. Finally, use arccosine to get from the cosine of the angle to the angle itself.

There is also a “slick” way, which relies on remembering the subtraction formula for tangents. tan(u-v) = [tan(u) - tan(v)] / [tan(u) + tan(v)]. Consider u as the angle between the positive x-axis and the line with slope -1, and v as the angle between the positive x-axis and the line with slope 2. Then the requested angle is u-v. We know tan(u) = -1 and tan(v) = 2, so substituting into the subtraction formula for tangents allows us to find tan(u-v). Finally, use arctangent of that value to find u-v.

Line segment is the part of line which have two endpoint and bounded by two distinct end points and it contain every point on the line which is between its endpoint.

Given that;

The graph is shown in figure.

We know that;

The domain of the graph is the value of x where the graph is defined.

Hence, By the graph;

Answer:

The answer is coefficient. Does that help?

Let's say Olive oil = O, Balsamic Vinegar = B, Salad Dressing = S

For the salad dressing she uses 3 parts olive oil to 2 parts balsamic vinegar

So we can say for every 3 ml of olive oil, she needs 2ml of balsamic vinegar

We know she has 120ml of olive oil, so first step is to find how much balsamic vinegar she will be using.

Remember, for every 3 ml of Olive Oil, she needs 2ml of Balsamic Vinegar .

if you do 120 divided by 3 = 40

So she is making 40 times the amount of salad dressing.

This means you need to multiply the  amount of balsamic vinegar by 40.

B = 40 times 2 = 80 ml

So now for the dressing we know :

She uses 120 ml of olive oil and 80 ml of balsamic vinegar.

So to find how many ml of salad dressing she can make, you just add the two.

S = O + B = 120 + 80 = 200 ml

Using proportions, it is found that she can make 80 milliliters of salad dressing.

The rule of three is:

3 parts of olive oil - 2 parts of balsamic vinegar.

120 ml - x ml

Applying cross multiplication:

[tex]3x = 2(120)[/tex]

[tex]3x = 240[/tex]

[tex]x = \frac{240}{3}[/tex]

[tex]x = 80[/tex]

She can make 80 milliliters of salad dressing.

How to graph an equation?

To graph an equation using the slope and y-intercept. Write the equation in the form y = mx + b to find the slope m and the y-intercept (0, b). Next, plot the y-intercept. From the y-intercept, move up or down and left or right, depending on whether the slope is positive or negative.

Given data ,

Let the function be f ( x ) = ( 1 / 2 ) x⁵

Now , to know which graph represents the equation mentioned, you can put some values of x in the equation and evaluate the value of y

So , when x = 1

y = ( 1 / 2 )

when x = 2

y = ( 1 / 2 ) × 2⁵

  = 2⁴

  = 16

when x = -1

y= ( 1 / 2 ) × ( -1 )⁵

 = - ( 1 / 2 )

So , by plotting all the points of x and y in the graph , Option a ) satisfies the solution

Hence , the solution is Option a)
