The answer you are looking for is C. 8.
To find this you could Pythagorean Theorem. The base or bottom of the triangle would be 7, and the "leg" of the triangle would be 3. In this instance, we will call 3 "a" and 7 "b". We use these two numbers to find the missing value, which is "c" or the hypotenuse.
The formula for Pythagorean Theorem is "a^2 + b^2 = c^2". Then we follow these steps.
- Fill in the known values. 3^2 + 7^2 = c^2
- Simplify the squared numbers. 9 + 49 = c^2
- Add the numbers together. 58 = c^2
- Square root both sides. √58 = c.
- Round up to the nearest whole mile. 7.615 = c; c = 8.
Here's a picture to show how I did this. I hope this helps!
Answer:
85 feet
Step-by-step explanation:
60^2+60^2=7200
square root of 7200 is 85
Answer: Pigs = 21
Chicken = 45
Step-by-step explanation:
Let the pigs be represented by p
Let the chicken be represented by c.
From the question,
p + c = 66
4p + 2c = 174
4 × ( p + c = 66)
1 × (4p + 2c = 174)
4p + 4c = 264
- 4p + 2c = 174
2c = 90
c = 90/2 = 45
There are 45 chickens
Simce the farmer has a total of 66 animals, the number of pigs will be:
= 66 - 45
= 21 pigs
Equivalent for 3/7
7* 3 = 21 then 3* 3 = 9
so 3/7 = 9/21
Yes they are equivalent because they both equal 24 because 240÷10=24 and 288÷12=24 so yes they are equivalent
