Find the area of this composite shape
11 cm
"11 cm
18 cm
6.5 cm
Answer:
166.5 cm squared
Step-by-step explanation:
Multiply 11x11 =121
Multiply 7x6.5 =45.5 (we get the 7 because 18-11=7)
Then we add 121 and 45.5 and get 166.5
The area of this composite shape is 166.5 square cm
Area of composite figuresComposite figures are figures that has more than 1 shape. The given figure is made up of two rectangles.
The area of the shape is given as shown below;
Area = (11*11) + (7 * 6.5)
Area = 121 + 45.5
Area = 166.5 square cm
Hence the area of this composite shape is 166.5 square cm

how do you write the equation from a rose graph
Answer:
equation is in form: r = a cos(nθ) or r = a sin(nθ)
If length of petal is given in graph, that gives a value.
n value is from number of petals
Step-by-step explanation:
hope this helps :D
(btw I hate rose graphs...)
Answer:
Rose curve equations have two forms: r = a cos(nθ) and r = a sin(nθ) where a ≠ 0 and n is a positive integer. Petals have length determined by a. If n is odd, the number of petals is n. However, if n is even, the number of petals is 2n.
Step-by-step explanation:
Is this table of values linear?
Answer:
No
Step-by-step explanation:
Linear values will increase by a common difference. For example, a linear function might increase by 6 every time or -4. However, this table does not; each time it increases by a different factor. Since there is no common difference and it does not follow an arithmetic function it is not linear.
Answer:
Step-by-step explanation:
Not linear.
If the inputs were 1, 2, 3, 4 and we wanted a linear function, one such function would be 1, 2, 3, 4 or 10, 20, 30, 40, and so on.
The given table shows that y increases faster and faster as x increases.
From x = 1 to x = 2, y increases from 1 to 2 (an increase of 1).
From x = 2 to x = 3, y increases from 2 to 6 (an increase of 4).
From x = 3 to x = 4, y increases from 6 to 24 (an increase of 18)
No, the table does not represent a linear function.
Tania has a set of nesting rings. This table shows the relationship between the radius of a ring and the ring's circumference.
What is the circumference for the nesting ring with a 9.5 cm radius?
Answer:
59.66 cm
Step-by-step explanation:
Circumference of a circle = 2πr
π = 3.14
r = radius = 9.5

Answer:
P = 131 degrees
Step-by-step explanation:
We know that the sum of the interior angles of a triangle is 180 degrees
The exterior angles shown form a straight line with the corresponding interior angle
So the two interior angles can be calculated
The sum of two angles on a straight line is 180 degrees
By subtracting the exterior angles from 180, we can get the two interior angles which we can add to the angle at P to give 180
Thus;
P + (180-162) + (180-149) = 180
P + 18 + 31 = 180
P = 180-31-18
P = 131

What is revenue?Revenue is the money generated from normal business operations, calculated as the average sales price times the number of units sold. It is the top line (or gross income) figure from which costs are subtracted to determine net income. Revenue is also known as sales on the income statement.
Total Revenue = Number of Units Sold X Cost Per Unit
According to the question
a> The company wants to reduce total expenses to $1,300.
Then expenses would i cut is from
Rent expenses as all other expenses are very important but we can try to lower out rent expenses by $1,300.
b>After the decision the impact will be on profit is
It will increase our profit by $1,300 as
Profit = Sales - Expenses
c>if the company increases prices 20%
i.e
If price will be increases then revenue will also increase by 20%
As Total Revenue = Number of Units Sold X Cost Per Unit
Therefore ,
Total Revenue = 356500 * 1.2
= 427800
d> If the cost of supplies (inputs) decreases,
The impact on profit is it will increase
as if cost of supplies decreases that is it will decrease the supplies expenses also which will cost in less expense and higher profit .
e> If the supply of a product goes down,
It will lower the revenue or sales also
as Total Revenue = Number of Units Sold X Cost Per Unit
But if supply of a product goes down and price per unit increase it will maintain the sales or revenue .
Hence, The answers of questions given are explained .
