Answer: 70
Step-by-step explanation:
a^2 + b^2 = c^2
24^2 + b^2 = 74^2
576 + b^2 = 5,476
-576 -576
b^2 =4,900
(square root)
b =70
We started with one small box. Then we added a box on the side to make it twice as long. Then we added boxes on top to make it twice as tall. Then we added boxes behind it to make it twice as long. That gave us 8 of the small boxes.
Then we multiplied 8 boxes by 24 staplers in each box and got 192 boxes.
Answer:
5 x 2 inside the parenthesis
Step-by-step explanation:
We need an order of operations to ensure we always arrive at the correct answer. It gives us a consistent way to work with numbers. We use the mnemonic device like PEMDAS to remember the correct order.
P-parenthesis
E-exponents
M-multiplication
D-division
A-add
S-subtract.
We apply them left to right doing inner operations before outer operations.
There fore our first step is in the parenthesis and multiplication because it is the inner most operations. 5 x 2 inside the parenthesis.
1. let x be the number of months paid. 2. let 33x be the dollar value of the cost paid after x months (no initial fee yet) 3. let 33*5=165 be the cost paid on monthly basis for 5 months . But the total cost is $225 dollers after 5 months. the implies that the membership fee is 225 -165=dollers. 4. let TC be the total cost. 5. then the total cost TC=33x+60. 6. after 10 months , total cost TC= 33*10+60=330+60=390dollers.
