Answer: 11.4 m

Step-by-step explanation:

The scenario depicted is that of a right angled triangle with the 7 meters being the base and the 9 meters being the height.

The length of the ladder will therefore be the Hypothenuse.

Using the Pythagorean Rule:

a² + b² = c²

with c being the hypothenuse

7² + 9² = c²

49 + 81 = c²

c²= 130

c = √130

c = 11.4 m

From which set of dimensions could a triangle be constructed?

lutik1710 [3]

The longest side of the triangle has to be less than the sum of the two other sides.

A ⇒ 7 + 8 = 15
B ⇒ 8 + 5 < 14
C ⇒ 6 + 3 < 10
D ⇒ 2 + 6 > 7

The answer is D, because the longest side length (7) is shorter than the two other side lengths (2 and 6).

WINSTONCH [101]

Answer:

Sam would receive 17 boxes of books.

Step-by-step explanation:

Given:

Books ordered by Sam this week is given as:

120 books on Monday

286 books on Wednesday

To find the number of boxes Sam received if there are 24 books in each box.

Solution:

Total books ordered by Sam this week = $120+286=406$

The total number of books is packed in boxes of 24 books each and received by Sam.

Thus, total number of books must be divided by 24 to find the number of boxed Sam would receive on Friday.

Total number of boxes of Books received by Sam = $\frac{406}{24}=16.91\approx 17$

Thus, Sam would receive 17 boxes of books.
