(Please Help) You have a board of wood that measures 9 3/4 feet. You cut a piece off the board measuring 2 15/16 feet and then another piece measuring 4 3/8 feet. You now need a piece that is 2 1/2 feet long. You say your remaining board of wood is long enough. Is this reasonable?
Answer:
no
Step-by-step explanation:
9 3/4 -(2 15/16+4 3/8)
give a common denomenator for all of the fractions.
=9 12/16 - (2 15/16 + 4 6/16)
=9 12/16 - 7 5/16
=2 7/16
so the answer is 2 and a litle bit less than half so the answer is no..
A store owner paid $20 for a book. She marked up the price of the book by 15% to determine its selling price. What is the selling price of the book?
Answer:
$23
Step-by-step explanation:
15% is equivalent to 10% + 5%. 10% of $20= $2. 5% of 20=$1. 1+2=3. $20 + $3 = $23

Answer:The mean is equal to the median.
Step-by-step explanation:
Median is the middle value of a given data set. In a symmetric distribution, the data on the left side of the median is equal to the data on the right side of the median. Therefore, the mean of that data is equal to the median of the symmetric distribution.
Step-by-step explanation:
One possible assignation can be:
from 0 to 2, the student buys lunch in the cafeteriafrom 3 to 9, the student brings lunch from home.How to assign the numbers?
We assume that in the spinner the probability of landing on each one of the given sections is the same.
So, to simulate a case where 30% of the students buy lunch in the cafeteria.
We need to assign 3 of the 10 sections to "buys lunch in the cafeteria" and the other 7 sections to "bring lunch from home"
That assignation can be made in any order you want, for example:
from 0 to 2, the student buys lunch in the cafeteriafrom 3 to 9, the student brings lunch from home.If you want to learn more about probability, you can read:

A photograph is in the shape of a rectangle. It has a length of (x - 2) inches and a width of (x - 2) inches. What is the area of the photograph? Would this be [tex]x^{2}[/tex] + 4?
Answer:
yes
Step-by-step explanation:
two negatives make a positive and two x would make x squared
Answer:
You are actually off most people make that common mistake but the answer would actually be x^2 - 4x + 4, not x^2 + 4
Step-by-step explanation:
(x - 2) times (x - 2) = x^2 - 2x - 2x + 4 from here people tend to make a mistake by completely erasing out (-2x - 2x) thinking they cancel each other out, but here is what should have happened (-2x + -2x) = -4x so put it all together you would have x^2 - 4x + 4.
You can't do anything else because (+4) is a solid number of its own although there is an "x" in (x^2 and -4x) in "x^2" the x is with an exponent while in "-4x" the x is alone. It isn't the same as "x^2" so you wouldn't be able to get a proper answer even if you tried...it would most likely be an error

Coretta is covering her locker door with crate paper. The door is shaped like a rectangle and has an area of 192 square inches. Find the value of x that is reasonable for this situation.
PLEASE HELP ITS DUE SOON
A. 7.09
B. 9.73
C.19.73
D. -19.73
The value of x that is reasonable for this situation is 9.73.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have the width of locker is x+ 10.
Then, we can consider the length as x.
Now, the area of of door = 192 square inches
So, x(x+10)= 192
x² + 10x = 192
x² + 10x - 192 = 0
Now, using Discriminant Method
x = (-10 ±√ 100 + 768) / 2
x= (-10 ± 868)/2
x= 9.73 or x= -19.73
So, the required value is 9.73 unit.

Answer:
228
Step-by-step explanation:
[Formulas Below]
Surface area means the sum of all the shapes on the figure, which means we have to calculate each area of the shapes on the triangular right prism and add them up. To calculate the triangles, we plug in 6 and 5 and get 15. Since there are 2 triangles, we multiply it by 2. Next, we have to find the areas of the rectangles. 11 * 6.5 = 71.5 (There are two of them so you multiply by 2), and 11 * 5 = 55. Finally, we add all of these up. 15 * 2 + 71.5 * 2 + 55 = 30 + 55 + 143 = 228. The surface area is 228.
Area of Triangle = (Length * Height)/2
Area of Rectangle = Length * Width
