find the sale price to the nearest cent .. $40 sweater; 33%discount
Answer:
$26.80
Step-by-step explanation:
(I don't know exactly how other people were taught to do percentages, but this is how I was taught and I find it the easiest for me.)
You are going to subtract your percentage number by 100.
100 - 33 = 67
This will give you your multiplier so you can then get your answer but you have to turn it into a decimal.
0.67 x 40 = 26.80

What is the area of this composite shape?
Answer: 51 sq in
The explanation are in the photos
Answer: 51 in
Step-by-step explanation:
To do this you need to split the composite shape into two separate shapes; a triangle and a rectangle.
To work out the area of the rectangle you have to do 6x7=42
Then to work out the area of the triangle you have to do 13-7 to get the height of only the triangle h (height)=6
Then to find out the base of the triangle you have to do 6-3 as 6 is the overall length b (base)=3
The formula for the area of the triangle is b×h/2 (base times height divided by 2) which is also displayed as 3x6/2=9 which is the area of the triangle
So to work out the area of the composite shape you have to add the area of the rectangle and the area of the triangle (42+9).
Find the marginal cost, marginal revenue, and marginal profit functions. C(x) = 7x; R(x) = 9x − 0.001x2
Given:
The cost function is
[tex]C(x)=7x[/tex]
The revenue function is
[tex]R(x)=9x-0.001x^2[/tex]
To find:
The marginal cost, marginal revenue, and marginal profit functions.
Solution:
We know that,
[tex]Profit=Revenue-Cost[/tex]
[tex]P(x)=R(x)-C(x)[/tex]
[tex]P(x)=9x-0.001x^2-7x[/tex]
[tex]P(x)=2x-0.001x^2[/tex]
The marginal cost, marginal revenue, and marginal profit functions are the derivatives of cost, revenue and profit functions respectively.
Marginal cost function is
[tex]C'(x)=7\dfrac{d}{dx}x[/tex]
[tex]C'(x)=7(1)[/tex]
[tex]C'(x)=7[/tex]
Marginal revenue function is
[tex]R'(x)=9(1)-0.001(2x)[/tex]
[tex]R'(x)=9-0.002x[/tex]
Marginal profit function is
[tex]P'(x)=2(1)-0.001(2x)[/tex]
[tex]P'(x)=2-0.002x[/tex]
Therefore, the marginal cost, marginal revenue, and marginal profit functions are [tex]C'(x)=7[/tex], [tex]R'(x)=9-0.002x[/tex] and [tex]P'(x)=2-0.002x[/tex] respectively.
Find the space inside a rectangle with a width of 18 and length of 20
Answer:

Katie is 1.73 m tall. George is 7 cm shorter than Katie. How tall is George?
Give your answer in m
Answer:
Katie height =1.73 m
George height =7 cm
formula
1 meter =100 cm 7/100 =0.007m
so George height =0.007 m
height of George = Katie height - George height
= 1.73 - 0.007 m
= 1.723 mHeight of George = 1.723 mStep-by-step explanation:

Lori bought some cookies for $2 each and muffins for $3 each. She bought twice as
many muffins as cookies and spent $16. How many cookies did Lori buy?
Answer:
2 cookies
Step-by-step explanation:
let c represent cookies, m represent muffins. set up a system of equations:
2c+3m=16
m=2c
(the top equation shows that cookies are $2 each, and muffins are $3, and that the total cost is $16. the bottom equation shows that Lori bought twice as many muffins as cookies).
then solve the system of equations by substitution, substituting 2c for m in the top equation:
2c+3(2c)=16
2c+6c=16
8c=16
c=2
this means that lori bought 2 cookies.
Answer:
2 cookies
Step-by-step explanation:
let c = no. of cookies
2c = no. of muffins
The cost for c cookies is 2c since each cookie was $2
and the cost of 2c muffins is 3(2c) = 6c since each muffing was $3
The total cost = 2c + 6c = 16
8c = 16
c = 2
So, she bought 2 cookies and 4 muffins
