Mathematics
1 answer:
Bas_tet [7]3 years ago
6 0

Answer:

625

Step-by-step explanation:

1. parenthesis first, so it simplifies to ((6+(8)2÷4*1)/2)^4

2. pemdas says that multiplication and division go before addition and subtraction, so ((6+(8)2÷4*1)/2)^4 becomes ((6+16÷4*1)/2)^4 ---> ((6+4)/2)^4

3. then simplify inside of the parenthesis, so it becomes 5^4, which is 625

Dominick weighs 30 pounds more than his sister. Together they weigh 330 pounds. How much does Dominick weigh?
german

Domik weights 30 pounds more than his sister

Together they weigh 330 pounds

Let "x" represent the weight of Dominik's sister, then his weight can be expressed as "x+30"

And their total weight can be calculated as:

x+(x+30)=330

From this expression you can calculate the value of x:

\begin{gathered} 2x+30=330 \\ 2x+30-30=330-30 \\ 2x=300 \\ \frac{2x}{2}=\frac{300}{2} \\ x=150 \end{gathered}

x=150 pounds

x+30=150+30=180 pounds

Dominik weights 180pounds and his sister 150 pounds

5. A pole has to be erected at a point on the boundary of a circular park of diameter 13 metres in
lesya [120]

Answer:

Thus, it is possible to erect a pole at a point p on the boundary of the park at distances 5m and 12m respectively from gates B and A.

Step-by-step explanation:

Let P be the required location of pole .

A and B are the two gates.

Let the distance of pole at p from gate be 'x' meters

i.e. PB = x m

•°• AP = (x + 7)m and AB = 13 m

•°• AP² + BP² = AB² => (x +7)² + x =13²

Rejecting x =-12, we get x = 5

•°• PB = 5m

and

AP = 12m

(I hope this helped :)
