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
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.

Pam wants to put a banner across her garage door to congratulate her son on his college graduation. The garage door is 9 feet high and 12 feet wide. How many feet long should the banner be to fit the garage door?
9514 1404 393
Answer:
15 feet
Step-by-step explanation:
The diagonal of a 9 ft by 12 ft rectangle is given by the Pythagorean theorem as ...
d = √(9² +12²) = √225
d = 15 . . . . feet
The banner should be 15 feet long to match the length of the door diagonal.
What angle maximizes the area of the triangle below?
Answer:
90°
Step-by-step explanation:
Area of triangle with sides a and b and included angle Θ:
A = (1/2)ab * sin Θ
dA/dx = (1/2)ab cos Θ
(1/2)ab cos Θ = 0
cos Θ = 0
Θ = 90°
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?
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

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?
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.
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.
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
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]

Find the x-intercepts for the parabola defined by the equation below.
y= x^2-9x+ 18
A. (-3,0) and (-6,0)
B. (0, -3) and (0, -6)
c. (0,3) and (0,6)
D. (3, 0) and (6.0)
Answer:
The answer correct (D).
The x-intercepts for the parabola defined by the equation y= x²-9x+ 18 are (3, 0) and (6.0)
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax2+bx+c=0. with a ≠ 0 .
We have to find the x-intercepts for the parabola y= x²-9x+ 18
We have to make y as zero to find the x intercepts
x²-9x+ 18 = 0
This equation is in the form of quadratic equation
x² -6x-3x+18=0
x(x-6)-3(x-6)=0
(x-3)(x-6)=0
x=3 or x=6
Hence, the x-intercepts for the parabola defined by the equation y= x²-9x+ 18 are (3, 0) and (6.0)
