Micheal and Tracy are carpeting their family room that is 14 1/2 feet long and 12 1/4 feet wide. To find the amount of carpet needed micheal says to multiply 15 1/2 and 12 1/4 and Tracy says to multiply 12 1/4 and 15 1/2 . Who is right how much carpet is needed
Answer:
Area of carpet = 177.625 ft²
Step-by-step explanation:
Given:
Length of room = [tex]14\frac{1}{2}[/tex] = 14.5 ft
Width of room = [tex]12\frac{1}{4}[/tex] = 12.25 ft
Find:
Area of carpet
Computation:
Area of carpet = lb
Area of carpet = (14.5)(12.25)
Area of carpet = 177.625 ft²
Micheal estimation = 15.5 x 12.25 = 189.875
Tracy estimation = 12.25 x 15.5 = 189.875
Both wrong.
What is the approximate percent decrease when a fish count goes down from 850 to 500? The percent decrease is approximately 40%. The percent decrease is approximately 70%. The percent decrease is approximately 140%. The percent decrease is approximately 240%.
Answer:
The percent decrease is approximately 40%.Step-by-step explanation:
Step one:
given data
initial count of fish= 850
final count of fish= 500
Required
% decrease
Step two:
% decrease= final-initial/initial*100
substitute
% decrease= 850-500/850*100
% decrease=350/850*100
% decrease= 0.41*100
% decrease= 40.1%
The percent decrease is approximately 40%.
Answer:
The percent decrease is approximately 70%
A wall mosaic is being designed. The tiles for the wall make a rectangular grid consisting of mºrows and m columns. Which expression shows the number of tiles on the wall?
[tex]m {8}^{?} [/tex]
[tex]2 {m}^{3} + 2 {m}^{5} [/tex]
[tex] {m}^{3} + {m}^{5} [/tex]
[tex] {m}^{15} [/tex]
Answer:
m^8
Step-by-step explanation:
The number of tiles on the wall is m^(8)
What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
Here, it is given that :
number of rows = m³
number of columns = m^(5)
Now, we have to find the number of tiles in a wall
= rows * column
= m³ * m^(5)
= m^(3+5)
= m^(8)
hence, the number of tiles in a wall is m^(8)

Given that P(A) = 0.5, P(B) = 0.2, and P(A and B) = 0.1, which best describes the relationship between events A and B?
Answer: Events A and B are independent.
=============================================
Explanation:
Note how,
P(A)*P(B) = 0.5*0.2 = 0.1
which matches exactly with P(A and B) = 0.1
Therefore,
P(A and B) = P(A)*P(B)
is a true statement. This further leads to events A and B being independent.
please help!!!!!! im not too sure how to answer this.
The perimeter of a rectangle is 42 inches. If the width of the rectangle is 6 inches, what is the length?
A. 36 inches
B. 21 inches
C. 15 inches
D. 30 inches
Answer:
The length is 15 inches.
Step-by-step explanation:
Perimeter of rectangle = 2L + 2W
If W = 6, then 2W = 2*6, which is 12.
Now, 2L + 12 = 42.
Solve for L.
2L + 12 = 42
2L = 30
L = 15
1. 7a x 8 =168
2. 7+ 2a =23
3. 6c + 8c =28
Answer:
first is 3, then 8, then it's 2
Answer:
1. a = 3
2. a = 8
3. c = 2
Step-by-step explanation:
7a x 8 = 168
56a = 168 <-- 7a x 8 =56(56a)/56 = 168/56 <-- divide both sides by 56a = 37 + 2a = 23
(7 + 2a) - 7 = 23 - 7 <-- subtract 7 from both sides2a = 16(2a) / 2 = 16/2 <-- divide both sides by 2a = 26c + 8c = 28
14c = 28 <-- 6c + 8c = 14cc = 2 <-- divide both sides by 14find the slope of the given line in the equation:

Express 9/10 in simplest form.
Answer:
9/10 in simpliest form is 9/10
Step-by-step explanation:
In order to simplify a fraction there must be:
1. A number that will divide evenly into both the numerator and denominator so it can be reduced. No such number exists for 9 and 10.
or
2. The numerator must be greater than the denominator, (an improper fraction), so it can be converted to a mixed number. 9 is not greater than 10.
9/10 as a decimal: 0.9
9/10 as a percent: 90%

Select the correct answer. If A= and Ab= what is the value of matrix b
Answer: C. [tex]B=\left[\begin{array}{ccc}1\\3\\-5\end{array}\right][/tex]
Step-by-step explanation: I got this right on Edmentum.
Several operations such as addition, subtraction, multiplication, etc. can be performed on matrices. The value of matrix B is:
[tex]B =\left[\begin{array}{c}1&3&-5\end{array}\right][/tex]
Given that:
[tex]A =\left[\begin{array}{ccc}2&4&-2\\4&-5&7\\2&7&5\end{array}\right][/tex]
[tex]AB =\left[\begin{array}{c}24&-46&-2\end{array}\right][/tex]
Let matrix B be:
[tex]B =\left[\begin{array}{c}a&b&c\end{array}\right][/tex]
The product of A and B is as follows:
[tex]\left[\begin{array}{ccc}2&4&-2\\4&-5&7\\2&7&5\end{array}\right] \times\left[\begin{array}{c}a&b&c\end{array}\right][/tex]
Multiply the rows of A to the column of B. So, we have:
[tex]AB =\left[\begin{array}{ccc}2a+4b-2c\\4a-5b+7c\\2a+7b+5c\end{array}\right][/tex]
This means that:
[tex]\left[\begin{array}{ccc}2a+4b-2c\\4a-5b+7c\\2a+7b+5c\end{array}\right] = \left[\begin{array}{c}24&-46&-2\end{array}\right][/tex]
By comparison, we have:
[tex]2a + 4b - 2c = 24[/tex] --- (1)
[tex]4a - 5b + 7c = -46[/tex] --- (2)
[tex]2a + 7b + 5c = -2[/tex] --- (3)
Multiply (1) and (3) by 2
[tex]2a + 4b - 2c = 24[/tex] --- (1)
[tex]4a + 8b - 4c = 48[/tex] ----- (5)
[tex]2a + 7b + 5c = -2[/tex] --- (3)
[tex]4a + 14b + 10c = -4[/tex] ---- (6)
So, we have:
[tex]4a - 5b + 7c = -46[/tex] --- (2)
[tex]4a + 8b - 4c = 48[/tex] ----- (5)
[tex]4a + 14b + 10c = -4[/tex] ---- (6)
Make 4a the subject in each of the equations
[tex]4a = -46 + 5b - 7c[/tex]
[tex]4a = 48 - 8b + 4c[/tex]
[tex]4a = -4 - 14b - 10c[/tex]
[tex]4a = 4a[/tex]. So, we have:
[tex]-46 + 5b - 7c = 48 - 8b + 4c[/tex] and [tex]-46 + 5b - 7c = -4 - 14b - 10c[/tex]
Simplify both expressions
[tex]-46 + 5b - 7c = 48 - 8b + 4c[/tex]
[tex]5b + 8b - 7c - 4c = 48 + 46[/tex]
[tex]13b - 11c = 94[/tex]
[tex]-46 + 5b - 7c = -4 - 14b - 10c[/tex]
[tex]5b+14b - 7c + 10c = 46-4[/tex]
[tex]19b + 3c = 42[/tex]
Make c the subject
[tex]c = \frac{42 -19b}{3}[/tex]
Substitute [tex]c = \frac{42 -19b}{3}[/tex] in [tex]13b - 11c = 94[/tex]
[tex]13b - 11 \times (\frac{42 - 19b}{3}) = 94[/tex]
Multiply through by 3
[tex]39b - 11 \times (42 - 19b) = 282[/tex]
Open bracket
[tex]39b - 462 + 209b = 282[/tex]
Collect like terms
[tex]39b + 209b = 282+462[/tex]
[tex]248b = 744[/tex]
Solve for b
[tex]b = \frac{744}{248}[/tex]
[tex]b = 3[/tex]
Solve for c
[tex]c = \frac{42 -19b}{3}[/tex]
[tex]c = \frac{42 - 19 \times 3}{3}[/tex]
[tex]c = \frac{-15}{3}[/tex]
[tex]c = -5[/tex]
Solve for a in [tex]4a = -4 - 14b - 10c[/tex]
[tex]4a = -4 - 14 \times 3 - 10 \times -5[/tex]
[tex]4a = 4[/tex]
Divide by 4
[tex]a = 1[/tex]
Recall that matrix B is:
[tex]B =\left[\begin{array}{c}a&b&c\end{array}\right][/tex]
Hence, the value of matrix B is:
[tex]B =\left[\begin{array}{c}1&3&-5\end{array}\right][/tex]

Answer:
Net pay of Kevin is $440
Step-by-step explanation:
Pay per hour = $6.50
Total Hours worked= 60 hours
Total pay for 60 hours worked = 6.50 x 60 = $390
Amount received as tips = $148
Now, his pay would be: 390+148 = $538
Amount deducted for meals = $21
Now his pay would be = 538-21 = $517
Now, Pay of Kevin is $517
Payroll taxes deducted from pay = $77
Net pay of Kevin= 517-77 = &440
