Samantha is wall papering her bedroom and wants to make sure that she bought enough wall paper. Each wall in her room measures 10 feet by 11 feet. How many rolls of wall paper will Samantha need if each roll covers a total of 25 square feet.
Answer:
17.60
Step-by-step explanation:
Look at the room carefully, the length of the room is 11 feet
And the height = 10 feet
The area of the 4 walls of the room = 4( 11×10) = 440 sq ft
Area covered by each roll = 25 sq ft
= 440/25 = 17.60 rolls
Therefore we require 17.60 rolls to cover a rectangular room on all four sides.

The formula uppercase S = StartFraction n (a Subscript 1 Baseline plus a Subscript n Baseline) Over 2 EndFraction gives the partial sum of an arithmetic sequence. What is the formula solved for an?
Answer:
[tex]a_n = 2S - a_1[/tex]
Step-by-step explanation:
Given
[tex]S = \frac{a_1 + a_n}{2}[/tex]
Required
Determine the formula for [tex]a_n[/tex]
What this question implies is to solve for [tex]a_n[/tex]
[tex]S = \frac{a_1 + a_n}{2}[/tex]
Multiply both sides by 2
[tex]2 * S = \frac{a_1 + a_n}{2} * 2[/tex]
[tex]2 S = a_1 + a_n[/tex]
Subtract [tex]a_1[/tex] from both sides
[tex]2S - a_1 = a_1 - a_1 + a_n[/tex]
[tex]2S - a_1 = a_n[/tex]
[tex]a_n = 2S - a_1[/tex]
Hence; the formula to solve [tex]a_n[/tex] is [tex]a_n = 2S - a_1[/tex]

Which number is irrational, and integer, and a real number A) -4/2 B) there is no such number
Answer:
Step-by-step explanation:
real number can be irrational or integer.
otherwise there is no number which can be irrational,integer and real (all together)
Answer: The answer is B) there is no such number.
Step-by-step explanation:
So we have to find which number is irrational, and integer, and a real number. Let's examine the problem closely:
- irrational means not rational and cannot be represented by a simple fraction (like pi )
- an integer means a number that can be written without a fractional component ( -1, 2, 0, -10000 )
- and a real number means that it is not imaginary ( like 2i, [tex]\sqrt{-1}[/tex] )
And our choices here are:
- -4/2
- there is no such number
Let's take a look at -4/2. This number is a fraction, but it can be simplified down to -2/1, which is an integer. -2 is a real number, not an imaginary number. But, -2 is not irrational, because as it just was shown here, it CAN be represented by a fraction. So, since only two out of the three criteria are true, then we have to consider choice B.

on a piece of paper, graph y<-3/4x+2. Then determine which answer choice matches the graph you drew.
Answer:
D. Graph D
Step-by-step explanation:
The "y <" tells you two things: (1) shading will be below the line, where y-values are less than those on the line, and (2) the line will be dashed, because the "equal to" case is not included.
Only one graph has a dashed line with shading below: Graph D.
A corollary needs which of the following geometric terms to be proven true?
A Inverse
B. Identity
C. Theorem
D. Common notion
A corollary needs theorem to be proven true.
What is corollary?" A corollary is defined as the statement which either need little explanation or no explanation to prove true. It is based on already proven statements."
According to the question,
Inverse is not consider as already proven statement. It is function which needs to calculate.
Hence, Inverse is not true.
Identity are formula which is not a geometric term.
Hence , identity is not true.
Theorem are geometric term, which can be used to prove other statements true as it is already proved.
Hence, corollary needs theorem to be proven true.
Common notion are like postulates which are consider as without proof. Common notion are not limited to geometry.
Hence, common notion is not true.
Therefore, A corollary needs theorem to be proven true.

I’m a constant function. There are two possible ways to write me; one way being slope-intercept form and the other being constant form
(I don’t really understand what this question is asking)
Answer:
constant function has the same output no matter what are the inputs and it is written in the form : y=b where b is a constant that does not change. the slope of this function always equal to zero.
slope intercept form : y=mx+b ( where m=0)
constant form : y=b ( y equal a constant that does not change)
Find the slope of the line through points (2,-4) and (2,7)
Answer:
Undefined
Step-by-step explanation:
Use rise/run, (y2 - y1) / (x2 - x1)
Plug in the values:
(7 + 4) / ( 2 - 2)
11/0
= undefined, since you cannot divide by zero
The slope is undefined

A 2000 kilogram sports car accelerates at a ratr of 30 meters per second squared. The velocity of the car is v=at where a is acceleration in meters per second squaref and t is tome in seconds. The kinetic energy of the car is KE = 1/2 mv^2
Answer:
KE = 900,000t²
Step-by-step explanation:
The formula for calculating the kinetic energy of a body is expressed as KE = 1/2mv² where;
m is the mass of the sport car = 2000kg
v is the velocity of the car
Since v = at
v = 30t
Substituting the given values into the KE formula;
KE 1/2 * 2000 * (30t)²
KE = 1000*900t²
KE = 900,000t² Joules where t is the time measured in seconds
Answer:
KE = 900,000t²

what is the product of 2/3 3/4 4/5 5/6 6/7
Answer:
2/7
Step-by-step explanation:
Since multiplication fractions is just multiplying all numerators together and all denominators together, we can group all these fractions together into one big fraction as they are all being multiplied together:
(2x3x4x5x6x)/(3x4x5x6x7)
Because each term is being multiplied together, if it also appears in the denominator, they will cancel each other out (as x multiplied by y and then divided by y is just x as the ys cancel each other out)
Therefore we are just left with 2/7.

A research company wants to test the claim that a new multi vitamin helps improve short term memory state the objective of the experiment suggest a population determine the experimental and control groups and describe a simple procedure
Answer:
To test the effects of the multi-vitamin, we must test it on people with short-term memory loss. So the population should be people with short-term memory loss. The independent variable is the multi-vitamin and the dependent variable is the short term memory state of the people being tested. A control group can consist of people with short-term memory loss NOT being treated by the multi-vitamin.

Which expression would be easier to simplify if you used the commutative property to change the order of the numbers?
A. 30+(-12)+70
B. 60+40+(-25)
C. 1/3+2/3+(-1/4)
D. -10+(-20)+1/2
Answer: A. 30+(-12)+70
Step-by-step explanation:
Commutative property of addition is given by : a+b = b+a , where a and b can be any expression of real numbers.
It basically changes the order of the so that simplification of any expression becomes easier.
In A. we use this property as
30+(-12)+70 = 30+[(-12)+70]
= 30 + [70+(-12)] [we switched order of (-12) and 17]
= 30+70-12
= 100-12
= 88
The rest of the expression already arranged accordingly, there is no need to apply commutative property to change the order of the numbers.
So the correct option is A. 30+(-12)+70.
