Answer:
5
Step-by-step explanation:
Mode means most, so it's the number you see most.
Step-by-step explanation:
Pyramid
1/2 * 12 * 15
6 * 15 = 90
90 * 4 = 360cm
Cube
12 * 12 = 144
144 * 4 = 576cm
576 + 360 =
936 cm² of paint
Area of a rectangle is length x width.
Let the width = x
The length would be x +7. ( 7 inches longer than the width)
Area = 20
Set up the formula:
20 = x * x+7
Simplify the right side:
20 = x^2 + 7x
Subtract 29 from both sides:
X^2 + 7x -20 = 0
Solve using the quadratic equation
X = -b + sqrt(b^2 -4ac) / 2a
X = -7 + sqrt(7^2-4(1)(-20) / 2(1) (exact answer)
X = 2.178908 ( as a decimal)
The width is 2.178907 inches (round as needed)
The length would be 9.178907 inches ( round as needed.)
Depending on how you round, when you multiply them together you get approximately 20 square inches.
The answer is 5, the 2 are disqualified and 5 remains
Responder:
Escala uno
0,2 m
Los 0.067m
Explicación paso a paso:
Dado que :
Escala uno = 1: 1000
Escala dos = 1: 3000
La escala 1 tendrá una vista más detallada porque el dibujo en la escala 1 será tres rublos más grande que el dibujo producido con la escala 2. Por lo tanto, la escala más grande debería tener una vista más detallada.
Un lago de 200 m de largo en realidad:
Tamaño del lago según escala 1
1 = 1000
x = 200
Cruz multiplicar
1000x = 200
x = 200/1000
x = 0,2 m
Según escala 2:
1 = 3000
x = 200
3000x = 200
x = 200/3000
x = 0,067 m
