You would use the pythagorean theorem. a² +b² =c²

side² +side² = hypotenuse²

So for 1) 8² + 15² = c²
64+225=c²
289=c²
√c² = √289
c = 17

2. 7²+24² =c²
49+576= c²
c²=625
√c²= √625
c = 25

3. 5²+13²=c²
25+169=c²
c² = 194
√c² = √194
c = 13.93

4. 24² + 45² =c²
576 + 2025 =c²
c² = 2601
√c² = √2601
c = 51

5.
Plug each choice into the pythagorean theorem. a² +b² =c²

3²+4² = 5²
9+16= 25
25=25

6²+8²=10²
36+64=100
100=100

16²+63²=65²
256+3969=4225
4225=4225

8²+9²=10²
64+81=100
145=100 Since 145 does not equal 100 it is not a right triangle

What is the result of subtracting the second equation from the first?
Ronch [10]

Answer:

-5x + 0y = -11

The y terms are eliminated

Step-by-step explanation:

- 4x – 2y = -2

X - 2y = 9

We want to subtract the second equation from the first

Distribute a minus sign to all the terms in the second equation

- 4x – 2y = -2  

X - 2y = 9

= (-5x + 0y = -11)

A soccer ball has a 35 cm diameter. what is the volume of the contents of the ?
Anettt [7]

Answer:

To calculate the volume of a sphere, use the formula v = ⁴⁄₃πr³, where r is the radius of the sphere. If you don't have the radius, you can find it by dividing the diameter by 2. Once you have the radius, plug it into the formula and solve to find the volume.

Step-by-step explanation:

To find the volume of a soccer ball,the formula is V=4/3 πr^3,where r is the radius and π=3.14. A regulation soccer ball has a radius of 35cm. find the volume of a soccer ball to the nearest cubic centimeter. This is just some to keep in mind.
