Isabel bought some books for $6 each and received a discount of $8 off of her total purchase. She spent $58 after the discount. How many books did she buy?
Answers
Answer:
She bought 11 books.
Step-by-step explanation:
If she spent $58 after the discount, then you can add 8+58 to see what the price would have been. 8+58=66. Then you divide 66 by 6 because each book costs $6. 66/6 = 11

To mail a letter to Vienna, Austria the post office charges a flat rate of $9.25 and an additional $0.75 for every ounce the letter weighs. The cost of mailing a letter is determined by the equation y=0.75x+9.25, where y is the cost of the postage and x is the weight of the letter in ounces.
Answers
Answer:
See attachment for graph
Step-by-step explanation:
Given
[tex]y = 0.75x + 9.25[/tex]
Required [Missing from the question]
Graph the equation
First, we determine two points that satisfy the equation.
Let: [tex]x = 1[/tex]
[tex]y = 0.75x + 9.25[/tex] becomes
[tex]y = 0.75*1 + 9.25 = 0.75 + 9.25 =10[/tex]
This point will be represented as:
[tex](1,10)[/tex]
Let: [tex]x = 5[/tex]
[tex]y = 0.75x + 9.25[/tex] becomes
[tex]y = 0.75 * 5 + 9.25 = 3.75 + 9.25 = 13[/tex]
This point will be represented as:
[tex](5,13)[/tex]
So, we plot: [tex](1,10)[/tex] and [tex](5,13)[/tex]

A monitor measures 10.6 inches by 16.8 what is the length of the diagonal
Answers
Step-by-step explanation:
We will use pythagoras' Theorem for this question
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
where c is the longest side (in this case, the diagonal)
a and b are the 2nd and 3rd longest side (interchangeable)
given a = 10.6, b = 16.8,
[tex] {c}^{2} = {10.6}^{2} + {16.8}^{2} \\ {c}^{2} = 112.36 + 282.24 \\ {c}^{2} = 394.6 \\ c = \sqrt{394.6} \\ = \frac{ \sqrt{9865} }{5} inches[/tex]

Answer: Carat
Step-by-step explanation:
It is given that 1 atomic unit is equivalent to
[tex]8.3\times 10^{-24}\ \text{carat}[/tex] and [tex]1.66\times 10^{-21}\ mg[/tex]
Express carat and milligram in the atomic mass unit, that is
[tex]1\ \text{amu}\equiv 8.3\times 10^{-24}\ \text{carat}\\1\ \text{carat}\equiv \dfrac{1}{8.3\times 10^{-24}}=1.204\times 10^{23}\ amu[/tex]
For milligram
[tex]1\ \text{amu}\equiv 1.66\times 10^{-21}\ mg\\1\ mg\equiv \dfrac{1}{1.66\times 10^{-21}}=6.02\times 10^{20}\ \text{amu}[/tex]
clearly, carat is greater than milligram

Triangle DEF has an angle D measuring 25 degrees and an angle E
measuring 50 degrees.
What is the measure of angle F, in degrees?
Answers
Answer:
The angle F of the triangle DEF measures 105 degrees.
Step-by-step explanation:
Given that triangle DEF has an angle D measuring 25 degrees and an angle E measuring 50 degrees, to determine what is the measure of angle F in degrees, knowing that the sum of the internal angles of every triangle gives a total of 180 degrees, we must perform the following calculation:
180 - 50 - 25 = F
130 - 25 = F
105 = F
Therefore, the angle F of the triangle DEF measures 105 degrees.

3. Find the values of the constants in each of the following:
(1) f(x) = ax + b, a and b are constants, f2) = 7,f(1) = -1
Answers
9514 1404 393
Answer:
a = 8; b = -9
Step-by-step explanation:
Filling in the given values gives you two equations.
7 = a(2) +b
-1 = a(1) +b
Subtracting the second equation from the first gives ...
(7) -(-1) = (2a +b) -(a +b)
8 = a . . . . . simplify
Using this value in the first equation gives ...
7 = (8)(2) +b
b = 7 -16 = -9
The constants are a = 8, b = -9.
The outside dimensions of a rectangular cooler WITHOUT its lid is 26 inches by 14 inches, with a height of 16 inches. The cooler is 2 inches thick. What is the volume inside the cooler
Answers
Answer:
3080 square inches
Step-by-step explanation:
I like to draw things out. So I drew this cooler out, with the dimensions of 26x14x16. It the cooler is 2 inches thick, I need to remove 2 inches from each side of the cooler. So I took 4 inches off of the 26 and the 14 so the length and width become 22 and 10 respectively. Then I took 2 inches off the bottom of the cooler so the 16 became 14. This gives me the new dimensions of 14x22x10.
