Answer: 112 pieces
Step-by-step explanation:
1. Rewrite
as a decimal. Divide the numerator and the denominator of the fractional part and add it to the integer part:

2. You know that each metal rod is 15 inches long. Then, you must divide the lenght of each one by 3.6:

3. The waste is 0.16, therefore, you obtain 4 pieces from a metal rod. The total pieces obtained from 28 metal rods are:

The answer to the first one is $7.60 because when you add $0.40 with $0.90, you get $1.30. because you have to add this to the money in the piggy bank, you would get $7.60; $6.30 + $1.30
A) using prime factorization (dividing with a prime factor until everything is a prime number, then multiplying the prime numbers by each other once), u can calculate their lcm
122=2x61
15=5x3
834=2x3x139
then multiply the prime factors once,
2x3x5x61x139= 254,370
b) i’m assuming that u solve the equation first bc u didnt put any commas
42-12-16=14
3-92+20=-69
do prime factorization
14=2x7
-69=-23x3
multiply the factors
-23x7x3x2=-966
Answer:
18.0
Step-by-step explanation:
The three lines form a right triangle where 10 and 15 are the two legs of the triangle. You can use the pythagorean theorem to solve for the length of x.
x = 
x = 18.028 (approximately 18)
