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

The​ government, through a subsidy​ program, distributes ​$10000000. If each person or agency spends 55​% of what is​ received,
Lady bird [3.3K]

Answer:

$ 12,222,222.22

Step-by-step explanation:

Let P be the initial amount distributed,

Since, the spending in first instance = 55% of P

= 0.55(P)

In second instance = 55% of (0.55(P)) = 0.55² P

In third instance = 55% of (0.55² P) = 0.55³ P,

............................., so on.....

Thus, total increase in spending = 0.55P + 0.55² P + 0.55³P.....

We know that,

0.55P, 0.55²P, 0.55³P,..............

Is a GP with infinite number of terms,

Having first term, a = 0.55P,

Common ratio, r = 0.55,

Hence, the sum of the above series,

S = \frac{a}{1-r}

=\frac{0.55P}{1-0.55}

=\frac{0.55P}{0.45}

=\frac{11P}{9}

Here, P = $ 10000000,

Therefore, total amount increase = \frac{11\times 10000000}{9}

=\frac{110000000}{9}

= $ 12,222,222.22
