Answer:
The hike is 4.5 miles
Step-by-step explanation:
We divided 3 by 2 since 3 is 2/3 done
3 ÷ 2 = 1.5
So now we know what 1/3 is; 1.5
So now we multiply 1.5 by 3
1.5 × 3 = 4.5
Thus, the hike is 4.5 miles long

Polynomial Operations 1&2 Test 10 of 1610 of 16 Items Item 10 The height of a poster is 7x+10 and its perimeter is 20x+24 . What is the width of the poster?
Answer:
3x + 2
Step-by-step explanation:
The height of a poster is 7x+10 and its perimeter is 20x+24 . What is the width of the poster?
The shape of a poster = Rectangular shape
Hence:
The Perimeter of a Rectangle (Poster) = 2L + 2W
Where:
Length = Height = 7x + 10
Perimeter = 20x + 24
Therefore:
20x + 24 = 2(7x + 10) + 2W
20x + 24 = 14x + 20 + 2W
2W = 20x + 24 - (14x + 20)
2W = 20x + 24 -14x - 20
2W = 6x + 4
W = (6x + 4)/2
W = 3x + 2
Therefore, the width of the poster
= 3x + 2
Help me find the value of k asap please!
5/4(2 - k) = 2(3k - 1) - 2/3k
9514 1404 393
Answer:
k = 54/79
Step-by-step explanation:
You can eliminate fractions by multiplying both sides by 12.
15(2 -k) = 24(3k -1) -8k
30 -15k = 72k -24 -8k
54 = 79k
54/79 = k

How to calculate the surface area of a composite figure?Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.
When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.
Thus, we have:
[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]
That ∑ sign shows "sum"
We are given that;
The side of two hexagon is 2ft, painting measures 9*25ft.
Now,
In this case, s = 2 feet. Therefore, the area of one hexagonal window is:
Area = (3√3 × 2²)/2 Area = (12√3)/2 Area ≈ 10.39 square feet
Since there are two windows, we need to multiply this by 2 and subtract it from the total area of the wall:
225 - (2 × 10.39) ≈ 204.22 square feet
This is the area that needs to be painted. To find how much Deb will have to spend, we multiply this by $1.75 per square foot:
204.22 × $1.75 ≈ $357.39
Rounding this to the nearest dollar, we get:
$357
Therefore, by the area of painting the answer will be $357.

This ellipse is centered at the origin. Find it’s equation. Verticles: (0,-6) (0,6) Foci: (0,-2) (0,2)
The equation of the ellipse will be x² / 36 – y² / 32 = 1.
What is an ellipse?An ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called foci adds up to a constant. It is taken from the cone by cutting it at an angle.
This ellipse is centered at the origin.
Vertices: (0,-6) (0,6)
Foci: (0,-2) (0,2)
Then the equation of the ellipse will be given as
x² / a² – y² / b² = 1
Let c be the distance between the origin to foci.
Then we have
c = 2
And the value of a will be
a = 6
Then the value of a² will be
a² = 6² = 36
The value of b is the distance from center to one of the Co-vertices. Then the value of b² will be
a² – b² = c²
36 – b² = 2²
b² = 36 – 4
b² = 32
Then the equation of the ellipse will be x² / 36 – y² / 32 = 1.
