Answer:

The correct option is D.

Step-by-step explanation:

Given information: Point A lies outside of plane P.

Definition of Plane : A plane is a two-dimensional, flat surface that extends infinitely far.

Line perpendicular to a plane means, the line makes 90° angle with the plane.

Let as assume if a line passes through a point A and perpendicular to the plane P, then the number of possible lines are two.

It means line is perpendicular on two points of the plane,i.e., P₁ and P₂.

Since both line as perpendicular, therefore the length of line segment is same.

AP_1=AP_2

It is only possible, when

P_1=P_2

If a line passes through a point A and perpendicular to the plane P, then the number of possible lines is 1.

Therefore the correct option is D.

<em>Answer</em>


D) 1


<em>Explanation</em>

A perpendicular line makes a angle of 90° with a line or a plane.

If a line is to be drawn from a point to a line or a plain it can only be one. In this case a line is to be drawn through a point A to a plane P. If the line is to be perpendicular, then is is only one.


From the choices, the appropriate answer is D) 1

Sheila has 12 1/2 pounds of potato salad. She wants to divide the potato salad into containers, each of which holds 2 1/4 pounds
NeX [460]

Answer:

6 containers needed

Step-by-step explanation:

Given

Total = 12\frac{1}{2}\ lb ----- Size

Container = 2\frac{1}{4}\ lb ----- Size

Required

Determine the number of containers needed

This question illustrates the knowledge of fraction and division.

To get the number of containers needed, we simply divide the total size by the size of the container as follows;

Number = Total/Container

Number = 12\frac{1}{2}/2\frac{1}{4}

Convert to improper fractions

Number = \frac{25}{2}/\frac{9}{4}

Number = \frac{25}{2}*\frac{4}{9}

Number = \frac{100}{18}

Number = 5.5555556

Number = 6 --- Approximated

Chen kept track of how many baskets were made in a basketball game. After 6 minutes, 5 baskets were made. How long did it take u
Mekhanik [1.2K]

Answer:

Assuming the same pace was kept, it would take 9.6 minutes.

Step-by-step explanation:

We can find this by setting up a proportion and then cross multiplying.

5 baskets/6 mins = 8 baskets/x mins

5 * x = 6 * 8

5x = 48

x = 9.6

A ratio of boys to girls in the classroom is 4 to 5 if there are 20 girls how many boys would there be
Viktor [21]

Answer:

16 to 20

Step-by-step explanation:

Let's do our math.

4 to 5

8 to 10

12 to 15

16 to 20

In order to get to 20, you'd have to multiply 5 by 4. So in order to get an equal ratio, you multiply 4 by 4 and get 16.

I hope this helps!

BlackZzzverrR [31]

Answer:

1000 : 1000 : 1500

Step-by-step explanation:

2 + 2 + 3 = 7

3500 ÷ 7 = 500

2 × 500 = 1000

2 × 500 = 1000

3 × 500 = 1500

1000 : 1000 : 1500
