Find the third side in simplest radical form:

Leokris [45]

Answer:

a^2 + b^2 = c^2 (pythagorean theorem)

a^2 + 40^2 = 41^2 (plug in the known values)

a^2 + 1,600 = 1681 (simplify what you can)

a^2 = 81 (subtracted 1600 from both sides)

a= (81 under a radical) (I think this is what your answer will be, based on the problem)

a=9 (what the fully simplified answer is)

The number of apples in the box was less than 80. It is possible to divide all the apples evenly among 3, 4, and 5 children. How

ANEK [815]

Answer:

60 apples

Step-by-step explanation:

There are some number of apples in the box which is less than 80.

Now, it is given in the condition that all the apples can be divided evenly among 3, 4, and 5 children.

Therefore, the number of apples is a common multiple of 3, 4, and 5 which is less than 80.

Now, multiples of 3 less than 80 are 78, 75, 72, 69, 66, 63, 60, etc.

And, multiples of 4 less than 80 are 76, 72, 68, 64, 60, 56, etc.

Again, multiples of 5 less than 80 are 75, 70, 65, 60, 55, etc.

Therefore, the common multiple less than 80 is 60.

Hence, there were 60 apples in the box. (Answer)

At a school concert,the orchestra plays 8 songs that are 4.25 min long and 3 songs that are twice as long as each of the others.

Kazeer [188]

Answer: 59.5 minutes.

Step-by-step explanation:

1. You have the following information given in the problem above:

- 8 songs are 4.25 minutes long.

- 3 songs are twice as long as each of the others.

2. Therefore, the total time of 8 songs is:

$(8)(4.25min)=34min$

3. And the total time of the 3 songs is:

$(2)(3)(4.25min)=25.5min$

4. Therefore, you have that the result is:

$34min+25.5min=59.5min$

Arianna is buying plants for her garden. She buys 15 flowering plants for $96. Pink flowering plants sell for $8, and purple flo

Zielflug [23.3K]

Answer:

7 pink flowering plants

Step-by-step explanation:

Total number of plants = 15
Total cost = $96
Cost of pink flowering plant = $8
Cost of purple flowering plant = $5

<u>Let x and y be the number of plants bought. Then we have equations:</u>

8x + 5y = 96
x + y = 15 ⇒ y = 15 - x

<u>Substituting y in the first equation:</u>

8x + 5y = 96
8x + 5(15 - x) = 96
8x + 75 - 5x = 96
3x = 96 - 75
3x = 21
x = 7

Correct option is the second one
