the following shape has 1 pair of parallel sides. 3, 5, 8, 2, 6
To identify the shape with one pair of parallel sides, we need to consider the given set of numbers: 3, 5, 8, 2, 6.
A shape with one pair of parallel sides is a trapezoid. In a trapezoid, two sides are parallel while the other two sides are non-parallel.
Looking at the given set of numbers, we can form the sides of a trapezoid by pairing the numbers in the following way: 3, 5, 8, 2, 6.
The sides of the trapezoid can be represented as follows:
Parallel sides: 3 and 5 (forming the top and bottom sides)
Non-parallel sides: 8, 2, 6 (forming the slanted sides)
Therefore, the given set of numbers forms a trapezoid with one pair of parallel sides.

You are buying carpet to cover a room that measures 42 ft by 42 ft. The carpet cost $ 25 per square yard. How much will the carpet cost?
Explanation:
3 feet = 1 yard
14*(3 feet) = 14*(1 yard) .... multiply both sides by 14
42 feet = 14 yards
The carpet is 14 yards by 14 yards.
Its area is 14*14 = 196 square yards.
Since it costs $25 per square yard, this means the total cost is 25*196 = 4900 dollars

In Diagram 5, POQ is the diameter of the circle with centre O .Find the area, in cm², of the shaded region. Use 22/7
Answer:
B) 236.25
Step-by-step explanation:
POQ is a diameter of circle with centre O having diameter 21 cm. Whereas radius is 21/2 cm (as radius is considered as half of the diameter).
Assume that the tip of the triangle that touches the circle is point 'N'. So,
NO = radius = 21/2 cm
At present time we have a triangle of radius or height 21/2 cm, base 21 cm is enclosed in circle of diameter 21 cm. And are asked to find the area of the remaining region or you can say asked to find area of the shaded region.
Shaded region = Area of Circle - Area of Triangle
= πr² - 1/2 × b × h
= 22/7 × 21/2 × 21/2 - 1/2 × 21 × 21/2
= 21/2 × 1/2 [ 22/7 × 21 - 21 ]
= 21/4 [ 22 × 3 - 21 ]
= 21/4 [ 66 - 21 ]
= 21/4 [ 45 ]
= 21 × 11.25
= 236.25
Hence, the area of the shaded region is 236.25 cm².
A cylinder has a radius of 4x + 2 and a height of 5x + 4. Which polynomial in standard form
best describes the total volume of the cylinder? Use the formula V = 3.14r^2h for the volume of a
cylinder
Answer:
The answer is A!
Step-by-step explanation:
area of the base = pi*(4x+2)^2 = pi*(16x^2 +16x +4)
volume of cylinder = pi*r^2 *h
V = pi *(16x^2 +16x +4)(5x+4) = pi*(80x^3 +80x^2 +20x +64x^2 +64x +16) =
= pi*(80x^3 +144x^2 +84x +16)
Answer:
Step-by-step explanation:
The volume of a cylinder can be thought of as the area of a circle, scaled by the height of the cylinder. The formula for the volume of a cylinder is:
[tex]V=\pi r^2h[/tex]
Plug in the radius, and the height:
[tex]V=\pi (4x+2)^2(5x+4)[/tex]
Use FOIL to expand the squared binomial:
[tex]V=\pi (16x^2+16x+4)(5x+4)[/tex]
Bring out the binomial to the front of the trinomial:
[tex]V=\pi [(5x+4)(16x^2+16x+4)][/tex]
The process to multiply a trinomial by a binomial involves multiplying the trinomial by each term of the binomial:
[tex]V=\pi [(5x+4)(16x^2+16x+4)]=\pi [5x(16x^2+16x+4)+4(16x^2+16x+4)][/tex]
The rest is just distributing and tedious algebra:
[tex]V=\pi [(80x^3+80x^2+20x)+(64x^2+64x+16)][/tex]
Combine like terms and order the terms from highest exponent to lowest exponent. That is the definition of standard form:
[tex]V=\pi [80x^3+144x^2+84x+16][/tex]
[tex]V=4\pi [20x^3+36x^2+21x+4][/tex]

Wendy bought an $80 dress on sale for 40% off. How much did she pay for the dress?
Solution:
We know that:
Discounted price: Original price - (Original price × Discount)Original cost of dress: $80Discount: 40%This means that:
Discounted price of dress: 80 - (80 × 40%)Step-1: Convert "40%" into a fraction.
40% = 40/100Step-2: Find the discounted price.
Discounted price of dress: 80 - (80 × 40/100)Discounted price of dress: 80 - (4 × 40/5)Discounted price of dress: 80 - (4 × 8)Discounted price of dress: 80 - 32Discounted price of dress: $48Teresa has lived one-fourth of her life in England, one-fifth in Ireland, one-third in France and 13 years in

Will give BRAINLIST
Answer:
She is 60 years old
Step-by-step explanation:
The first thing we can do is convert each fraction to have a common denominator. The LCM of 5, 3, and 4 is 60.
[tex]\frac{1}{4} =\frac{15}{60}[/tex]
[tex]\frac{1}{3} =\frac{20}{60}[/tex]
[tex]\frac{1}{5} =\frac{12}{60}[/tex]
Add the numerators:
[tex]15+12+20=47/60[/tex]
Meaning that the time she lived in Switzerland is the remaining 13/60, and since she lived there for 13 years that means she lived for a total of 60 years because the numerator and denominator both equal 60.

Answer:
2x + 3y = 12 …equation 1
x– y = 1 … equation 2
To solve it by elimination method, let us multiply the second equation by 3
3x — 3y = 3 …equation 3
Now add the first and third equation
5x = 15
x = 3
From equation 2, y = x-1
y = 2
Hence x = 3, y = 2.
(b) 3x + y = 10
Since we have one equation and 2 variables, it cannot be solved by the elimination method.
To solve this, we can go for trial and error
Say y = 1, x = 3 or x = 5, y = —5
(c) x – 3y=1 …eq 1
3x – 2y + 4 = 0 …eq 2

Answer:[tex]2\sqrt{3}[/tex]
Step-by-step explanation:
Use pytha. theorem on leftmost triangle and get sqrt(13)
Use it again on the other triangle: 13+b^2=25
First, we find the hypotenuse of the first triangle
(Use the pythagorean theorem) : [tex]3^{2} + 2^{2} = 9 + 4 = 13[/tex]
So, the length of the side = [tex]\sqrt{13}[/tex]
Now, we find x :
x(squared) = [tex]5^{2} -\sqrt{13} ^{2}[/tex] = 25 - 13 = 12
