how many square feet of out door carpet will we need for this hole
Answer: Outdoor carpet should measure 30 square feet to cover the hole.
Step-by-step explanation:
Given:
Level 1 : Length = 5 ft ; Width = 2 ft
Level 2 : Length = 6 ft ; Width = 2 ft
Level 3 : Length = 4 ft ; Width = 2 ft
Area = L x W
Level 1 = 5 ft * 2 ft = 10 ft²
Level 2 = 6 ft * 2 ft = 12 ft²
Level 3 = 4 ft * 2 ft = 8 ft²
Total Area 30 ft²
find the value of x please
Answer:
x=21°
Step-by-step explanation:
in the isosceles triangle, if two sides are equal,then the angles opposite those sides are equal.
so, 2x=42° ( exterior angle of a triangle is equal to the sum of the two opposite interior angles)
x=21°
I have no idea how to round to the nearest cent
divide 100cm in the ratio1/2:1/4:1/5 to the nearest whole number
Step-by-step explanation:
step 1: add the ratios
1/2 + 1/4 + 1/5 = 0.95
step 2: divide each ratio by the total sum of the ratios and multiply by a 100
(1/2 ÷ 0.95) × 100 = 52.63 rounded off equals to 53
(1/4 ÷ 0.95) × 100 = 26.31 rounded off equals to 26
(1/5 ÷ 0.95) × 100 = 21.05 rounded off equals to 21
These ratios should add up to a 100
so the ratio are 53 : 26 : 21
the area of a triangle is 30ft² select Yes or No to tell if the dimensions could be the height and base of the triangle.
h=5ft, b=6ft Yes No
h=5ft, b=12ft Yes No
h=6ft, b=10ft yes no
h=6 ft, b=20ft yes no PLEASE HELP
Answer: No, Yes, Yes, No (in order)
Step-by-step explanation:
The area of a triangle is equal to the base*height/2.
The first choice:
Area = 6 ft * 5 ft/2
Area = 30 ft^2/2
Area = 15 ft^2
Therefore, this choice is not correct
The second choice:
Area = 12 ft * 5 ft/2
Area = 60 ft^2/2
Area = 30 ft^2
Therefore, this choice is correct
The third choice:
Area = 10 ft * 6 ft/2
Area = 60 ft^2/2
Area = 30 ft^2
Therefore, this choice is correct
The fourth choice:
Area = 20 ft * 6 ft/2
Area = 120 ft^2/2
Area = 60 ft^2
Therefore, this choice is not correct

Every angle in the polygon is a right angle. The area of the polygon is 426 in2. What is the length of the left side of the polygon? Show your work. help fast due in a few hours
Answer:

Step-by-step explanation:
First let's split the bottom part of the L in two parts of 19 and [tex]26-19=7 in[/tex] each. Now the whole area is made of two rectangles of sides [tex]19\times11[/tex] and [tex]7\times h[/tex],where h is the length of the left side. These two have to add up to 426 so

Answer should be in the form of a3 + b3
Answer:
Question:
[tex]\textsf{factor : \ } x^4+\dfrac{1}{x^2}[/tex]
Rewrite the expression using the exponent rule [tex]\dfrac{a^b}{a^c}=a^{(b-c)}[/tex]
[tex]\implies x^4+\dfrac{1}{x^2}=\dfrac{x^6}{x^2}+\dfrac{1}{x^2}[/tex]
Factor out common term [tex]\dfrac{1}{x^2}[/tex] :
[tex]\implies \dfrac{1}{x^2}(x^6+1)}[/tex]
Factor [tex](x^6+1)[/tex]:
Apply the exponent rule [tex](a^b)^c=a^{bc}[/tex] to get cubic exponents:
[tex]\implies x^6+1 = (x^2)^3+1^3[/tex]
Apply the sum of cubes formula: [tex]a^3+b^3=(a+b)(a^2-ab+b^2)[/tex]
where [tex]a=x^2[/tex] and [tex]b=1[/tex]:
[tex]\implies (x^2)^3+1^3=(x^2+1)((x^2)^2-x^2 \cdot 1+1^2)[/tex]
[tex]\implies (x^2+1)(x^4-x^2+1)[/tex]
Therefore,
[tex]\implies \dfrac{1}{x^2}(x^6+1)}=\dfrac{1}{x^2}(x^2+1)(x^4-x^2+1)[/tex]
Simplify by dividing the 2nd parentheses by [tex]x^2[/tex]:
[tex]\implies (x^2+1)\left(\dfrac{x^4-x^2+1}{x^2}\right)[/tex]
[tex]\implies (x^2+1)\left(x^2-1+\dfrac{1}{x^2}\right)[/tex]
Factor out [tex]x[/tex] from first parentheses:
[tex]\implies x\left(x+\dfrac{1}{x}\right)\left(x^2-1+\dfrac{1}{x^2}\right)[/tex]
what percent of 33 is 25? round your answer to the nearest tenth
Answer:
8
Step-by-step explanation:
multiply 25% by 33
25/100 × 33
= 8.25
rounded off = 8
The solution is 75.75 %
The number 25 is 75.75 percentage of 33
What is an 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.
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.
Given data ,
Let the percentage be represented as A
Now , the value of A is given by the equation
A % of 33 = 25
So , substituting the values in the equation , we get
( A / 100 ) x 33 = 25
Multiply by 100 on both sides of the equation , we get
33A = 2500
Divide by 33 on both sides of the equation , we get
A = 2500/33
The value of A = 75.75 %
Therefore , the value of A is 75.75 %
Hence , the number 25 is 75.75 % of 33

Steve is using the completing the square method to solve a quadratic equation. His first 2 steps are shown.
Given: 2x2 + 32x + 16 = 0
Step 1: 2? + 16x +8 = 0
Step 2: ? + 160 = -8
Write numbers in each box to correctly complete the square in Step 3.
Step 3: x2 + 16x+ ____=____
We muss add the polynomic expression [tex]x^{2}+16\cdot x = -8[/tex] by 64 on both sides.
How to apply the completing the square method to solve a quadratic equationIn this question we must apply the completing the square method to solve a quadratic equation, which consists in apply algebra properties to reduce part of a expression into a square perfect trinomial.
According to the step 2, we have the following expression:
[tex]x^{2}+16\cdot x = -8[/tex] (1)
By applying the principle of compatibility with addition and definition of addition, we have the following expression:
[tex]x^{2}+16\cdot x + 64 = - 8 + 64[/tex]
[tex]x^{2}+16\cdot x +64 = 56[/tex]
Now we proceed to solve the given expression:
[tex](x+8)^{2} = 56[/tex]
[tex]x+8 = \pm 2\sqrt{14}[/tex]
[tex]x = -8 \pm 2\sqrt{14}[/tex]
We muss add the polynomic expression [tex]x^{2}+16\cdot x = -8[/tex] by 64 on both sides. [tex]\blacksquare[/tex]

Here's the answer to that equation 9x+18
Step-by-step explanation:
You basically multiply 9 times (x+2) but since you don't know what x is you multiply 9 to each number (or variable) individually. So 9(x) + 9(2). The resulting equation is 9x + 18
