Answer:
Please check the attached figure a to visualize the array grid for 5, 7 and 11.
Step-by-step explanation:
As the given number be 5, 7 and 11.
An array is basically the display of things in rows and columns. Students tend to draw arrays for multiples of a given number.
For example, 2 × 1 means the objects are placed in two rows and 1 column.
The numbers 5, 7 and 11 are prime numbers as they have only two factors
- A prime number consists of just two factors, 1 and the number itself
- For example, 3 is prime number because the only factors of 3 are 1 and 3
So,
As the factors of 5 are 1 and 5. Therefore, the possible number of drawing all the possible arrays of 5 will be two which are
As the factors of 7 are 1 and 7. Therefore, the possible number of drawing all the possible arrays of 7 will be two which are
As the factors of 11 are 1 and 11. Therefore, the possible number of drawing all the possible arrays of 11 will be two which are

Answer:
BE = 49
Step-by-step explanation:
In triangle BDC
65^2=56^2+BD^2
65^2-56^2=BD^2
4225-3136=BD^2
1089=BD^2
33=BD
In triangle FDE
65^2=63^2+DE^2
4225-3969=DE^2
256 = DE^2
16=DE
since ED+DB=BE
THEREFORE
16+33=BE
49=BE
Not enough information. The question doesn't say how much one quart of paint covers.
EDIT: here's the solution
we have to find the total area of the 4 walls and subtract the area of the door. there are 2 walls with dimensions 16 by 10, and 2 walls with dimensions 16 by 12. so we have: 2(16*10)+2(16*12)=320+384=704 for the area of the walls. now, we can find the area of the door which is 3*8=24. <span>so we subtract the area of the door from the area of the walls, so we have: 704-24=680. </span><span>Since a quart of paint covers 100, then we divide and get 680/100=6.8 but since we need a whole number of quarts, we round up to get 7 quarts of paint. </span>
