The amount of money Shai saved:
![25.4 \times \frac{3}{4} = 19.05](https://tex.z-dn.net/?f=25.4%20%5Ctimes%20%20%5Cfrac%7B3%7D%7B4%7D%20%3D%2019.05)
The amount of money Nyah saved:
![19.05 \times 2 = 38.1](https://tex.z-dn.net/?f=19.05%20%5Ctimes%202%20%3D%2038.1)
The total amount three people saved:
![38.1 + 25.4 + 19.05 = 82.55](https://tex.z-dn.net/?f=38.1%20%2B%2025.4%20%2B%2019.05%20%3D%2082.55)
We are given a right triangle so that we can use the Pythagorean Theorem to solve for the measurement of the other leg. We use the expression written as:
c² = a² + b²
where c is the hypotenuse, a and b the other legs.
153² = 72² +b²
18225 = b²
b = 135 cm
Hope this answers the question. Have a nice day.
Answer:
8
Step-by-step explanation:
= f (x) = -2 log 4 (x + 5) - 4
= 4 (-2 + 5) - 4
= So you do -2 + 5 because they are in ( ) so you do it first so (-2 + 5) = 3
= So now you have 4 (3) - 4
= You do 4 and (3) because when you have a 4 by a ( ) that means you multiply.
= 4 (3) which is the same as 4 × 3 which is 12.
= then you do 12 - 4 which is 8.
= 8 is your answer.
I hope this helps.
