The minimum amount of extra cardboard needed to construct a new box is : 84in².

First step

Surface area=2(16) (5) in²+ 2(20in) (5in)  + 2(16in) (20in)

Surface area=1000in²

Second step

Surface area if the length increase by 2 inches

Surface area=2(16) (5) + 2(20+2) (5in)  + 2(16in) (20+2)

Surface area=1084in²

Third step

Surface area=1084in²-1000in²

Surface area=84in²

Therefore the minimum amount of extra cardboard needed to construct a new box is : 84in².

Answer:

The area of the shape is 122.30 cm^2

Step-by-step explanation:

To calculate the surface area, we identify the side shapes

We have this as;

a rectangle that measures 11 cm by 3 cm, a rectangle that measures 3 cm by 6 cm, a rectangle that measures 8 cm by 3 cm, 2 triangles ( base and top) that has a height of 4.3 cm and a base of 11 cm

The area of the rectangles is simply the product of the side lengths

The area of the triangles is the product of the base and the height divided by 2; but since we have 2 exact triangles, we can simply multiply the base and the height to serve as the area of both

Thus, we have the area of the shape as follows;

(11 * 3) + (3 * 6) + (8 * 3) + (4.3 * 11)

= 33 + 18 * 24 + 47.3

= 122.30 cm^2

Answer: -3

Step-by-step explanation:

Given

Equations of the lines are

[tex]y=-x-4\\3y=cx-18[/tex]

For the system of linear equation [tex]a_1x+b_1y=c_1,a_2x+b_2y=c_2[/tex] has no solution if

[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}\neq \dfrac{c_1}{c_2}[/tex]

Rewrite the equations

[tex]x+y=-4,\ cx-3y=18[/tex]

Insert the values for the no solution condition

[tex]\Rightarrow \dfrac{1}{c}=\dfrac{1}{-3}\\\\\Rightarrow c=-3[/tex]

Therefore, for c=-3, the system of linear equation ha no solution.

Answer: The measure of JK is 60 and the correct option is d.

Explanation:

It is given that the points F, G, and H are the midpoints of the sides of triangle JKL , FG = 37, KL = 48, and GH = 30.

The point F is midpoint of JK, point G is midpoint of KL and the point H is midpoint of LJ as shown in figure .

According to the midpoint theorem, the line connecting the midpoints of two sides is parallel to the third and its length is half of the third side.

By midpoint theorem,

Therefore the measure of JK is 60 and the correct option is d.

The equations of ellipses[tex]2x^{2} +8y^{2} -12x+16y-174=0[/tex], [tex]4x^{2} +y^{2} +16x+4y+4=0[/tex],[tex]3x^{2}+12y^{2} +18x-24y-69=0[/tex] and [tex]x^{2} +9y^{2} -2x+18y-71=0[/tex] having the major axis lengths are twice their minor axis length.

Equations of ellipse

[tex]\frac{(x-h)^{2} }{a^{2} } +\frac{(y-k)^{2} }{b^{2} } =1[/tex]         (for horizontal major axis ,a>b)

[tex]\frac{(x-h)^{2} }{b^{2} } +\frac{(y-k)^{2} }{b^{2} }=1[/tex]           ( for vertical major axis, b>a))

Where, (h, k) is the center of ellipse.

The major axis of an ellipse is its longest diameter(a line that runs through the center and both foci, with ends at the two most widely separated points  on perimeter).

length of major axis = 2a       (where a is the length of semi major axis)

The minor axis of an ellipse is the line that contains the shorter of the two line segments about which the ellipse is symmetrical.

length of minor axis = 2b               (where b is the length of semi minor axis)

According to the given question

we have, the equations  of ellipses

A) [tex](4x^{2} +32x)+(25y^{2} -250y)+589=0[/tex]

[tex]4(x^{2} +8x)+25(y^{2} -10y)+589=0[/tex]

[tex]4(x^{2} +8x+b^{2} )-4b^{2} +25(y^{2} -10y+b^{2} )-25b^{2} +589=0[/tex]

[tex]4(x^{2} +8x+4^{2})-4(4^{2})+25(y^{2} -10y+b^{2} )-25(5^{2} ) +589=0[/tex]

[tex]4(x+4)^{2}+25((y-5)^{2} )-100=0[/tex]

[tex]4(x+4)^{2} +25(y-5)^{2} =100[/tex]

dividing both the sides by 100

[tex]4\frac{(x+4)^{2} }{100} +25\frac{(y-5)^{2} }{100} =1[/tex]

[tex]\frac{(x+4)^{2} }{25} +\frac{(y-5)^{2} }{4} =1[/tex]

[tex]\frac{(x+4)^{2} }{5^{2} } +\frac{((y-5)^{2} }{2^{2} }=1[/tex]

here, h=-4 and k=5

major axis =2a=2×5=10

minor axis=2b=2×2=4

⇒ the length of major axis is not twice the length of minor axis.

Similarly, we will do for the other equations

[tex]\frac{(x+2)^{2} }{2^{2} } +\frac{(y+2)^{2} }{4^{2} } =1[/tex]

here, h=-2 and k= -2

major axis: 2b=2×4=8

minor axis: 2a= 2×2=4

⇒ the length of the major axis is twice of the length of minor axis.

D).

[tex]x^{2} +4y^{2} +6x-8y-23=0[/tex]

[tex]\frac{(x+3)^{2} }{6^{2} } +\frac{(y-1)^{2} }{3^{2} } =1[/tex]

here, h=-3 and k=1

major axis: 2a=2×6=12

minor axis: 2b= 2×3=6

⇒ the length of major axis is twice of the length of minor axis.

E).

[tex]16x^{2} +y^{2} -64x+8y+16=0[/tex]

⇒[tex]\frac{(x-2)^{2} }{2^{2} } +\frac{(y+4)^{2} }{2^{2}} =1[/tex]

here, h=2 and k=-4

major axis: 2a=  4

minor axis :2b=4

⇒ the length of major axis is not the twice of minor axis.

F)

[tex]x^{2} +9y^{2} -2x+18y-71=0[/tex]

⇒[tex]\frac{(x-1)^{2} }{9^{2} } + \frac{(y+1)^{2} }{3^{2} } =1[/tex]

here, h=1,  and k=-1

major axis: 2a= 18

minor axis: 2b = 9

⇒ the length of major axis is twice to the length of minor axis.

The answer is below

Step-by-step explanation:

The question is not complete. A similar question is attached and is solved.

Solution:

A triangle is a polygon with three sides and three angles. Types of triangles are scalene, acute, obtuse, isosceles, equilateral and right angled triangle.

A right angled triangle is a triangle with one angle equal to 90 degrees. The longest side of a right angled triangle is known as the hypotenuse. Trigonometric identities is used to show the relationship between the angles and sides of a right angled triangle, i.e.:

sinθ = opposite/hypotenuse; cosθ = adjacent / hypotenuse; tanθ = opposite / adjacent

From the image:

let the distance from jack to the base of the building be x, hence:

tan60 = x / 60

x = 60 * tan60 = 104 ft.

Step-by-step explanation:

Answer:

The circumference is equal to 62.8 inches.

Step-by-step explanation:

To find the circumference we need to know the radius or the diameter.

In order to find the radius, we need to know that the area of a circle is equal to π[tex]r^{2}[/tex] (where r is the radius of the circle). Now we can find the radius by using this equation...

100π [tex]in^{2}[/tex]= π[tex]r^{2}[/tex] [tex]in^{2}[/tex]

Now we get...

100 [tex]in^{2}[/tex] = [tex]r^{2} in^{2}[/tex]

r in = 10 in

Therefore, the radius is equal to 10 inches. Now we can find the circumference by using the following formula...

Circumference = 2πr

Now we just sub in the values and get...

Circumference = 2πr = 2(3.14)(10) = 2(31.4) = 62.8

Now we knot that the circumference is equal to 62.8 inches.

Answer:

25π

Step-by-step explanation:

The area of a circle is calculated with the following formula :

r(radius) is given as 5 so the area is
