You can solve this question with pythagorean theorem >

Based on the information, you already have one side (a or b, doesn't matter, 12) and the hypotenuse (the cut, c, 15)
So:
1.

2. 144+

= 225
3.

= 225 - 144 = 81
4.

5.
Answer:
A. 3 13/20
B.3.8 kg
C.Strawberries
Step-by-step explanation:
In order to solve this we just need to find the amount of strawberries he picked, and if he picked 1 2/5 less in the morning and in the morning he picked 2 1/4, we just add that up to know how much he picked in the afternoon:

So in the afternoon he picked
.
Now he picked 5 3/10 kg of tomatoes but 1.5 were rotten, we just have to withdraw the rotten from the total:

So now we know that he picked
kg of good tomatoes.
If he picked in the afternoon and the morning 5.05 kg of strawberries, he picked more strawberries than tomatoes.
You are to calculate the # of students, based upon the starting volume of juice and the amount each student receives.
22 1/2 cups
This # of students is equal to ------------------------------
[1 1/4 cup / student ]
and this could be found easily by dividing 22.5 by 1.25: 18. There are 18 students.
$56.25, since 25% off can also be written as ÷4, since 25 is a quarter. 75÷4=18.75
75-18.75=56.25. Therefore, the answer is $56.25
A^2 + b^2 = c^2.....a and b are the legs and c is the hypotenuse
4^2 + b^2 = 5^2
16 + b^2 = 25
b^2 = 25 - 16
b^2 = 9
b = sq rt 9
b = 3 m
1 meter = 100 cm....so 3 meters = 3(100) = 300 cm
ur answer : the tree is 300 cm high
