Tess can make 9 throw pillows from the 6 yards of fabric.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Tess wants to make throw pillows for her couch. she has 6 yards of fabric. each pillow uses 2 over 3 yards of fabric.
The number of pillows will be calculated as,
Number of pillows = 6 ÷ ( 2 / 3 )
Number of pillows = ( 6 x 3 ) / 2
Number of pillows = 9

The length of a rectangle is 6 inches longer than its width. The perimeter of the rectangle is 28 inches. If x represents the
width of the rectangle in inches, which equation can be used to find its value?
Answer:
2(x + (x+6)) = 28
Step-by-step explanation:
2x+2x+12 = 28
4x + 12 = 28
4x=16
x=4
width = 4
length = 10
Answer:
d. 2(x + 6) + 2x = 28
Step-by-step explanation:
What is the first step to solve this equation 4m=44
F add 4 to both sides
G subtract 4 from both sides
H divide 4 on both sides
J multiply 4 on both sides
Answer: H
The first step is dividing 4 from both sides to find what m equals. By the way, its the only step :D

please help me this is geometry and i am so clueless!!!!!
Answer/Step-by-step explanation:
Problem 1:
E is the centroid of the triangle.
Centroid theorem states that the centroid is ⅔ of the distance of each vertex to the midpoint of the side opposite each vertex.
This implies that:
AE = ⅔(AD)
AE = 21
Therefore:
21 = ⅔(AD)
3*21 = 2(AD)
(3*21)/2 = AD
31.5 = AD
AD = 31.5
Problem 2: Apply the centroid theorem. Thus:
DE = ⅓(AD)
DE = 12
Therefore,
12 = ⅓(AD)
12*3 = AD
36 = AD
AD = 36

Answer:
x = 10, y ≈ 11.2
Step-by-step explanation:
Hi there,
We can find the length x first since we are given the lengths of the other two sides of the bottom right triangle. In order to find the length of x, it is important to know the Pythagorean Theorem and the fact that x is the hypotenuse.
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex] ← Pythagorean Theorem
To find x:
[tex]6^{2}[/tex] + [tex]8^{2}[/tex] = [tex]c^{2}[/tex]
100 = [tex]c^{2}[/tex]
c = 10
Therefore, the value of x is 10.
To find y:
We now know the length of two sides of the upper right triangle. The value of y can be found by using the theorem again.
[tex]a^{2}[/tex] + [tex]10^{2}[/tex] = [tex]15^{2}[/tex]
[tex]a^{2}[/tex] + 100 = 225
[tex]a^{2}[/tex] = 125
a = [tex]\sqrt{125}[/tex]
a = 11.2 when rounded to the nearest tenth.
Therefore, the value of y is approximately 11.2.
Hope this explanation is useful. Cheers.

Answer:
[tex]x = 1, -5[/tex]
Step-by-step explanation:
[tex]f(x) = x^2 +4x - 5[/tex]
Factor the expression. Factoring is the process of writing out an expression by using other expressions such that when the other expression are multiplied together, the resulting expression is the initial expression.
[tex]f(x)=x^2+4x-5[/tex]
[tex]f(x)=(x+5)(x-1)[/tex]
Now set the expression equal to zero to find the roots (also known are zeros) of the expression. Use the zero product property to find the answers, the zero product property states that any number times zero is zero.
[tex]0=(x+5)(x-1)\\[/tex]
[tex]x=-5,x=1[/tex]
Equipment with a cost of $634800 has an estimated salvage value of $30000 and an estimated life of 4 years or 14400 hours. It is to be depreciated by the straight-line method. What is the amount of depreciation for the first full year, during which the equipment was used for 3600 hours?
Answer:
$151,200
Step-by-step explanation:
According to the problem, calculation of the given data are as follows,
Cost of Equipment = $634,800
Salvage Value = $30,000
Estimated Life = 4 years
So, we can calculate depreciation for first year by using following formula,
Amount of depreciation = Depreciable base amount ÷ Estimated Life
Where, Depreciable base amount = Cost of Equipment - Salvage Value
= $634,800 - $30,000 = $604,800
By putting the value, we get
Amount of depreciation = $604,800 ÷ 4
= $151,200

What is the value of x in the figure at the right?
Answer:
B) 24
Step-by-step explanation:
This angle adds to 90 degrees, so to solve for x you need this equation:
(2x) + 42 = 90
Subtract 42 from both sides to get:
2x = 48
Divide 2 from both sides to get:
x = 24

Answer:
6% , 800$
Step-by-step explanation:
to answer the question we can use this proportion :
x : 100 = 30 : 500
x = (100*30)/500
x = 6%
for calculate the amount after 10 years we can use this formula
A = P(1+rt)
where P indicates the initial amount, r the rate (in decimal) and t the time of investment
A = 500(1 + 0,06 x 10) = 500(1 + 0,6) = 500(1,6) = 800 $

Question:
A group of health researchers survey a SRS of 300 teenagers, of whom 120 have low weekly outdoor activity levels and 180 have high weekly outdoor activity levels. Suppose that 35 percent of teenagers with low outdoor activity levels have allergies, and that 41 percent of teenagers with high outdoor activity levels have allergies. The researchers want to see the difference between the sample proportions. What will be the shape of the sampling distribution be and why?
Choices:
A. Approximately normal, because we expect 105 successes and 195 failures from teenagers with low levels, and 123 and 177 from teenagers with high levels, and all of these counts are at least 10.
B. Approximately normal, because we expect 42 successes and 78 failures from teenagers with low levels, and 73.8 and 106.2 from teenagers with high levels, and all of these counts are at least 10.
C. Not normal, because we expect fewer than 10 failures in both samples.
D. Not normal, because we expect fewer than 10 successes in both samples.

A certain building has a triangular shaped face to link up of the sides of the triangular base or 145 feet 257 feet in 290 feet five find the area of the base of the building
Answer:
18617.66 ft^2
Step-by-step explanation:
sides of triangular base
a= 145ft ,
b = 257ft ,
c = 290ft
calculate the area of the base
The base is a scalene triangle hence the area is calculated as follows
s = ( a + b + c ) / 2
= ( 145 + 257 + 290 ) / 2 = 346
Area of triangle = [tex]\sqrt{s(s-a)(s-b)(s-c)} = \sqrt{346(201)(89)(56)}[/tex]
= 18617.66 ft^2
