A repairman leans the top of an 26 foot ladder against the
top of a stone wall. The base of the ladder is 4.7 feet from
the wall. How tall is the wall? (Use Pythagorean Theorem:
a² + b2= c2)

Answers

Answer 1

Answer:

26.42139285

Step-by-step explanation:

26x26 + 4.7x4.7 = c2

676 + 22.9 =c2

698.09=c2

square root of 698.09=26.42139285

26.42139285 = c

Step-by-step explanation:

Sarah and Nathan each picked a bucket of strawberries. Sarah picked 4 1/4 and Nathan picked 3 3/4. How much more did Sarah pick than Nathan?

Answers

Answer: 1/2 buckets

Step-by-step explanation:

Sarah picked 4¹/₄ buckets of grapes and Nathan picked 3³/₄ buckets.

To find out how much Sarah picked more than Nathan, simply subtract Nathan's buckets from Sarah's.

First convert the fractions to improper fractions:

4¹/₄  = 17/4

3³/₄ = 15/4

As the have the same denominator, you can directly subtract them:

= 17/4 - 15/4

= 2/4

= 1/2 buckets

When you flip a baised coin the probability of getting tail is 0.75 How many times would you expect to get tails uf you flip the coin 320 times?

Answers

Answer: 60

How?: Well, we know that we have a 0.75 chance for tails. And on a coin, there is heads and tails. So, we multiply 0.75 (tails) by 320 and then divide that by 4. We do this because there is a 0.75 and 1 = 1.00. 1.00 - 0.75 = 0.25. 0.25 = 60

Is 4/5 greater or less than 45/100 how do you know

Answers

Answer:

4/5 is grater than 45/100

Step-by-step explanation:

Why?

because in percentage you make the bottom # a 100 one of them already has that and when it has 100 on the bottom it tells you that the top # is the percentage so 45/100 is 45%

now to make 4/5 a percentage what times 5 = 100?

20 does

so you times the top and bottom by 20

4*20= 80

now your fraction is 80/100  (top # tells you the %)

it's 80%

80% is grater than 45%

Answer:

4/5 is greater than 45/100.

Step-by-step explanation:

In order to figure it out, you need to make both fractions have common denominators. In order to do that, you figure out this:

5 times what equals 100? It's 20.

With fractions in this situation, whatever you do to the top, you have to do to the bottom. So, you multiply 4 times 20, which is 80.

In the end, you would end up with these two fractions:

80/100 and 45/100.

Obviously, 80/100 is greater than 45/100. In the beginning, 80/100 was originally 4/5. Therefore, 4/5 is greater than 45/100.
