Joseph borrowed a book from a library. The library charged a fixed rental for the book and a late fee for every day the book was overdue. The expression below shows the charges Joseph paid for the book when he returned it x days after the due date: 2 + 0.25x What does the coefficient of the expression represent?

Answers

The coefficient, 0.25, of the expression represents the late fee for every day the book was overdue.

And the constant, 2, represents the fixed rental fee.

The variable, x, represents the number of days Joseph had the book for.

“ Hanna is recovering hundreds of treasure chests from an ancient shipwreck. She is able to recover 8 chest every 4 hours
Complete the table using equivalent ratios.”
The table is:
8 chests every 4 hours

Lin has picked 1 1/2 cups of raspberries, which is enough for 3/4 of a cake. How many cups does she need for the whole cake?

Answers

(1.5 cups)/(.75 cake) = 2 cups/cake
Hey there!

To solve this, you can divide 1 1/2 and 3/4 . . .

1 1 /2 = 3/2
3/4 = 3/4

3/2 divided by 3/4:

3 x 4 = 12
2 x 3 = 6

12/6 = 2 <-----------

Lin needs 2 cups of raspberries for the whole cake.

Hope this helps you.

From our diagram we can see that angle HED equals to angel GED and angle GDE equals to angel HDE.                    

Two triangles are similar if the corresponding angles are equal, so their corresponding sides will be in equal ratio.

Upon setting ratios of corresponding sides of our triangle equal we will get,

[tex]\frac{EG}{GD} =\frac{EH}{HD}[/tex]

[tex]\frac{99.2}{62} =\frac{112}{(x+2)}[/tex]

Now we will use cross multiplication to solve our equation,  

[tex]99.2(x+2)=112\cdot 62[/tex]

[tex]99.2x+198.4=6944[/tex]

[tex]99.2x=6944-198.4[/tex]

[tex]99.2x=6745.6[/tex]    

[tex]x=\frac{6745.6}{99.2}[/tex]

[tex]x=68[/tex]

Therefore, value of x will be 68 ft.

Answers

There are 8 fluid ounces in a cup.
96 ounces divided by 8 ounces in a cup give you 12 cups.
96 oz =12 cups.
12 cups < 13 cups.

96 fluid ounces is less than 13 cups.

What is unit conversion?

It is the conversion of one unit to another unit with its standard conversion.

Examples:

1 hour = 60 minutes

1 minute = 60 seconds

1 km = 1000 m

We have,

To compare 96 fluid ounces and 13 cups, we need to convert one of the quantities so that they are in the same units.

One cup is equal to 8 fluid ounces.

So,

13 cups is equal to:

13 cups x 8 fluid ounces/cup

= 104 fluid ounces

Now,

We can compare 96 fluid ounces and 104 fluid ounces.

Which equation BEST represents the line of best fit for the scatterplot? A) y = x + 2 B) y = x + 1 C) y = x - 2 D) y = 2x + 1

Answers

Answer:

y=x+2 is the right answer

Step-by-step explanation:

Equation A best represents the line of best fit for the scatter plot. Option A is correct.

What is the line of best fit?

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

From option 1;

y= x+2

At,x=0 y=2

At,y=0 x=-2

The equation satisfy the graph in the best possible way. So that equation A best represents the line of best fit for the scatter plot.

Hence, option A is correct.

What is an equivalent expression?

An equivalent expression is an expression that has the same value but does not look the same. When you simplify an expression, you're basically trying to write it in the simplest way possible.

For the given situation,

Let the unknown number be x or 1/x

Option A)  2 1/2 divided by 8

If unknown number is x,

then, 8x = 2 1/2

⇒ x = 2 1/2 ÷ 8

So, option A is correct.

Option B) 5/2 x 1/8

⇒ [tex]\frac{(5)(1)}{(2)(8)}[/tex]

⇒ 5/16

So, option B is incorrect.

Option C) 8 divided 2 1/2

If unknown number is 1/x,

then, 8/x = 2 1/2

⇒ x = 8 ÷ 2 1/2

So, option C is correct.

Option D) ? x 8 = 2 1/2

If fraction is not known, it can be replaced by '?'

So, option D is correct.

Hence we can conclude that option B is the expression that does NOT answer the question.

Bert already has $50 but needs a total of at least $250 for his holiday. He gets paid £20 day for delivering papers. What is the least number of days he must work to get enough money for his holiday?

Answers

Bret would need to work for 8 days. He has $50 and need to pay $250. 250-50= 200. £20 is $27.59 200/27.59 =7.24 If £20 is a typo then 10 days.

Answer: Hi!

We know that Bert has $50, but he needs a total of at least $250 for this holiday. The differences between what he needs and what he has is:

$250 - $50 = $200

So he needs another $200.

He gets paid £20 a day and we want to know the number of days that he needs to work in order to obtain the $200.

The first step is to transform the £20 into dollars.

£1 = $1.27

then his daily pay in dollars is: 20*$1.27 = $25.4

Now let's call X the number of days that he needs to work to obtain the $200, we got:

X*$25.4 = $200

X = $200/$25.4 = 7.8

We should round up this result because we want a whole number.

X = 8, this means that Bert needs to work at least 8 days if he wants to have at least $250 for the holidays.

Statement A is the false one.
f(x)=(2x+1)(3x-2)
The zero product property says that f(x)=0 when either (2x+1)=0, or (3x-2)=0, or both.
We also know that the zeroes of an equation are the values of x when f(x)=0.
So f(x)=0 when (2x+1)=0 or (3x-2)=0 => x=-1/2 or when x=2/3. which are the roots of f(x).

A. the y-intercepts have nothing to do with the zeroes of f(x).
B. By definition of zero of a function, it is true that the values of x when f(x)=0 are the zeroes of f(x).
C. The zeroes of f(x) are the same as the ones calculated above, so it is true.
D. The x-intercepts of the lines are basically the zeroes of the function f(x), as explained above.  So the statement is true.
