Answer:
10. If you are asked to give the intersection of any plane and any line not in that plane, your answer will always be be a point
11. If you are asked to give the intersection of two non-parallel planes, your answer will always be a line
12. If you are asked to give the intersection of two lines, your answer will always be a point
Step-by-step explanation:
10. In space, a plane and a line that is not lying on this plane or parallel to it will always meet at point.
For instance, line PN intersects plane A at point N
11. The intersection of two planes in space is a line.
For instance, the intersection of planes QRST and PQRN is line RQ.
12. Two lines that are not parallel in the same plane will always intersect at a point.
For instance, lines TQ and PQ intersects at point Q
However, if two parallel lines are identical and coincide with each other, they intersect at infinitely many points.
Answer:
It would take 34.5 minuets for 9 people to paint 9 walls
Step-by-step explanation:
Divide 23 by 2 and you sound get 11.5
and 11.5 to 23 to get 34.5
The reason you must do it like this is because if they all do it at the same rate you need to know how long it would to for 3 people to do it so that you have a minimum point, then add the mid and min points to get the max point, 9 people.
Answer:
B. 8 cm, 5 cm, 11 cm.
Step-by-step explanation:
The volume of a right rectangular prism is
V = l*w*h
Lets check the options given to see if they equal 440 cm^3
A. 7 cm, 9 cm, 6 cm.
440 = (7*9*6 )
440 = 378 False
B. 8 cm, 5 cm, 11 cm.
440 = (8*5*11)
440 =440 True
C. 6 cm, 12 cm, 5 cm.
440 = (6*12*5)
440 = 360 False
D. 12 cm, 2 cm, 5 cm
440 = (12*2*5)
440=120 False
Answer:
La última página que Sandra deberá leer es la página 380.
Step-by-step explanation:
Sandra y Roberto tienen un libro de 760 páginas y se lo dividen, la pregunta es ¿Cuál es la última página que debería leer Sandra de tal manera que ella y Roberto pasen la misma cantidad de tiempo leyendo la novela?
Para que ambos pasen la misma cantidad de tiempo leyendo la novela, tendrían que dividirse el libro a la mitad, por lo que cada uno debería leer 760 ÷ 2 = 380 páginas.
Por lo que Sandra deberá leer de la página 1 a la 380 y Roberto leerá de la 381 a la 760.
Por lo tanto, la última página que Sandra deberá leer es la página 380.
Answer: 9/27
Step-by-step explanation:
To make it a fraction form answer, you keep the numerator and multiply the denominator by the whole number to make a new denominator:
