At a carnival booth, customers had to guess the number of jelly beans in a jar. Samantha guessed there were 375 jelly beans. The actual amount of jelly beans in the jar was 250. What is Samantha's percent error?

Answers

Answer 1

Answer:

150

Step-by-step explanation:

Answer 2

The required percent error by Samantha is 50%, as of the given condition,

What is the percentage?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

What is the error?

Errors are discrepancies between values that are seen and natural truths.

Here,
Samantha guessed there were 375 jelly beans.
The actual amount of jelly beans in the jar was 250.
Error percentage = 375-250 / 250 × 100
                           = 0.5 × 100
                           = 50%

Thus, the required percent error by Samantha is 50%, as of the given condition.

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?

Answers

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

Find the marginal cost, marginal revenue, and marginal profit functions. C(x) = 7x; R(x) = 9x − 0.001x2

Answers

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.

A grocery store sells 3 pounds of Granny Smith apples for $6.27. It sells 5 pounds of Red Delicious apples for $9.95. Which costs more per pound?​

Answers

Granny Smith apples cost more.



The Granny Smiths apples sells it for 2.09 per pound. Red delicious sells it for 1.99 per pound.


Step by step
Divide 6.27 by 3 you’ll get 2.09
Divide 9.95 by 5 you’ll get 1.99
And 2.09 is greater then 1.99 so Granny Smith sells it for more

Katie is 1.73 m tall. George is 7 cm shorter than Katie. How tall is George?
Give your answer in m​

Answers

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

Triangles have to equal up to 180° so there isn’t two answers that line up unless we’re picking one out of these it would be 20°
it could be 20 or 7. it can’t be 20 AND 7, because all triangles angles have to add up to 180, but either or is correct. both are possible answers i think.

Answers

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?

Answers

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).
