Find the Perimeter of the figure below, composed of a parallelogram and one semicircle. Rounded to the nearest tenths place
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

y = .5(x-2) 21
I need help with this problem
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

When Isabel makes salad dressing, she likes to make it with 3 parts olive oil to 2 parts balsamic vinegar. If Isabel has 120 milliliters of olive oil (and a sufficient supply of balsamic vinegar), how many milliliters of salad dressing can she make? Thanks!
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.
This question is solved by proportions, using a rule of three.For 3 parts of olive oil, she uses 2 parts of balsamic vinegar. How many millilitres of vinegar when she has 120 millilitres of olive oil?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.

Find the acute angle between the lines whose slopes are 2 & 1\3.
Answer:30 degrees
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.

Which graph represents f(x) = 1/2x^5
The solution is option a)
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)

In 2015, approximately 734.1 million tons of wheat were produced globally. China produced the most wheat of any country, at 130.2 million tons. What percentage of the world's wheat yield did China produce in 2015? Round your answer to the nearest whole number.
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.
