Answer:

The width of the banner is 4 inch and the length of the banner is  28 inch

Step-by-step explanation:

Given

Length is seven times its width

Let the width be "X", then length would be 7X

The banner is of rectangular shape.

Its area is 112 square inches

[tex]X* 7X = 112\\7X^2 = 112\\X^2 = 16\\X = 4[/tex]

Hence, the width of the banner is 4 inch and the length of the banner is 4*7 i.2 28 inch

4) In spherical geometry, some quadrilaterals are parallelograms.

In spherical geometry, some quadrilaterals are parallelograms is a true statement. Thus option D is correct.

Instead of the sort of geometries studied in trigonometry or solid geometry, the research of shapes on a structure's surface. White lines are large rounds in spherical, therefore any three layers intersect at two locations.

A spherical quadrilateral is a bounded surface that is homomorphic to a compact disk. It has four distinct local maxima called extremities, a Riemannian measurement that has constant curvature 1 everywhere else, aside from the corners, and or the demarcation arcs between it intersections. a dome shape. the collection of rectangular shapes with specified angles.

Therefore, option D is the correct option.

Answer:

The ratio should be 100 : 20. If it needs to be simplified then 5:1

Step-by-step explanation:

100 m is the distance traveled and the time it took was 20 seconds. Divide both sides by 20 and you get 5:1

(If it doesn't need to be simplified then 100 : 20)

Answer:A)Y =k x

               Y =5x

              B.Y=60

Step-by-step explanation:

Given that Y is directly proportional to x

mathematically , it Is represented as

Y ∝ x

Introducing the constant of proportionality, k. we have that

Y =k x

Now when y=30, x=6, k becomes

30=k 6

k=30/6=5

we now have the equation connecting them as

Y =5x

B) Now when x=12, y becomes

Y =5x

Y =5 X 12

Y=60

Answer:

the root of -1 is -1

Step-by-step explanation:

When multiplied by itself, the root is typically a specified number of times gives a specified number or quantity. So -1 × -1 = -1

Responder:

40 instalações

Explicação passo a passo:

Rolos totais de instalações adquiridas = 15

Rolos usados ​​por instalação = 3/8 de um rolo

O número de instalações que os 15 rolos podem durar pode ser calculado assim:

1 instalação = 3/8 rolo

x instalações = 15 rolos

Multiplicação cruzada

3/8 x = 15

x = 15 ÷ 3/8

x = 15 * 8/3

x = 5 * 8

x = 40

Answer:

pretty sure question 4 is numeric and question 5 is 78

Step-by-step explanation:

Answer:

here, suppose the missing length be X

hy ^2 = (one side square )^2 +(Other side square)^2

29^2= X^2 + 21^2

841 = X^2 + 441

X^2 = 841 - 441

X^2 = 400

X = 20 .........taking square root both side

the value is missing side length is 20 .

Answer:

d = 5t^2

Step-by-step explanation:

"d is directly proportional to the square of t"

d = kt^2

To find k use

"The ball falls 20 metres in a time of 2 seconds."

20 = k(2^2)

20 = k(4)

Divide both sides by 4

5 = k

Using k = 5 the formula becomes

d = 5t^2

Answer:

this is easy. you just need to write and equation that shows how many pounds of each fruit you can buy in total (x for 1 pound of grapes and y for 1 pound of watermelon). this would make the equation 32 = 4x + 2x.

The equivalent expression of 2(x² – 1) + 3x(x – 4) is 5x² - 12x - 2

The equivalent expression of the expression can be found as follows;

2(x² – 1) + 3x(x – 4)

open the brackets

2x² - 2 + 3x² - 12x

Therefore, let's combine like terms

2x² + 3x² - 12x - 2

Let's do the arithmetic for like terms

2x² + 3x² - 12x - 2

5x² - 12x - 2

Therefore, the equivalent expression of  2(x² – 1) + 3x(x – 4) is 5x² - 12x - 2

Step-by-step explanation:

Answer:

x=-4, y=7

Step-by-step explanation:

Answers : x = (15/6), y =

(1/2).

Step-by-step explanation:

Explanation: To solve this equation through elimination, you need to isolate one of the variable. You can isolate the y variable since the x variables can be subtracted and go away. Add the two equations to get rid of one variable. (6x + 6y = 18) + (-6 + 2y = -14) = (8y = 4). Now you need to solve for y. y = 4/8, y = 1/2. Now, plug the y back into one equation and solve for x. 6x + 6(1/2) = 18. 6x + 3 = 18. 6x = 15. x = 15/6. Plug the two answers back in to the equation to check your answers. 6(15/6) + 6(1/2) = 18, 15 + 3 = 18. -6(15/6) + 2(1/2) = -14, -15 + 1 = -14.

x = 0; x = [tex]\frac{-276}{5}[/tex]

Step-by-step explanation:

45x = 25x(57 + x)

45x = 1425x + 25x²

25x² + 1425x - 45x = 0

25x² + 1380x = 0

5x(5x + 276) = 0
