Answer:

24

Step-by-step explanation:

Since the ladder, wall, and ground form a right triangle, you can use this formula:

A squared + B squared = C squared

A = 7 feet

C = 25 feet

B = distance the ladder will reach

49 + B squared = 625

B squared = 625 - 49

B = square root of 576

B = 24 feet

It takes 212121 minutes for 555 people to paint 777 walls. How many minutes does it take 333 people to paint 555 walls?
Papessa [141]

Solution: We are given that:

5 people can paint 7 walls in 21 minutes

Therefore, 1 person can paint 7 walls in 21 \times 5=105 minutes

Which means 1 person can paint 1 wall in \frac{105}{7} =15 minutes

Now, 3 people can paint 1 wall in \frac{15}{3} =5 minutes

Therefore, 3 people can paint 5 walls in 5 \times 5=25 minutes

anna is shopping for a new backpack. The probability that the backpack is pink is 0.7, and teh probability that it is canvas is
harkovskaia [24]

The probability that it is pink or canvas is 0.9

Step-by-step explanation:

Let us revise the meaning of "or" , "and" on probability :

  • The use of the word "or" means that you are calculating the probability  that either event A or event B happened.  Both events do not have to happen
  • The use the word "and", means that both event A and B have to happen

The addition rules are:

  • P(A or B) = P(A) + P(B) ⇒ mutually exclusive (events cannot happen  at the same time)
  • P(A or B) = P(A) + P(B) - P(A and B) ⇒ non-mutually exclusive (if they  have at least one outcome in common)

Anna is shopping for a new backpack

∵ The probability that the backpack is pink is 0.7

∴ P(pink) = 0.7

∵ The probability that it is canvas is 0.7

∴ P(canvas) = 0.7

∵ The probability that it is pink and canvas is 0.5

∴ P(pink and canvas) = 0.5

Substitute the values above in the rule below

∵ P(pink or canvas) = P(pink) + P(canvas) - P(pink and canvas)

∴ P(pink or canvas) = 0.7 + 0.7 - 0.5

∴ P(pink or canvas) = 0.9

The probability that it is pink or canvas is 0.9

Round 96.39 to the tenths place
kykrilka [37]
9 is in the tenths place, since the rule is if a number is more than 5 you add one to it so 9 becomes a 10 and the 3 on its left becomes a 4. so the answer is 96.40 or 96.4
