my answer would be 10, but I might be wrong
Answer:
20) 2.084 meters
21) $75
22) 0.123 meters
23) 4 foot pieces
Step-by-step explanation:
20) divide the length by 4:
8.336 ÷ 4 = 2.084 meters
21) divide total cost by the amount of tickets:
39300 ÷ 524 = $75
22) subtract the smaller number from the greater number:
0.884 - 0.761 = 0.123 meters
23) the greatest common factor of 8 and 12 is 4, so he should cut each rope into 4 foot long pieces
a salesperson earns $175 per week plus a commission equal to 4% of her sales. This week her goal is to earn no less than $525.
Let x be the amount of sales in dollars
Commission = 4% of her sales x = 4% of x = 0.04 * x= 0.04 x
a salesperson earns $175 per week + 0.04 x
so Amount of earning in a week = 0.04 x + 175
This week her goal is to earn no less than $525.
So amount of earning is greater than 525
0.04 x + 175 >= 525
The required expression is 0.04 x + 175 ≥ 525
Answer:
Step-by-step explanation:
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
Let
y-------> the interest earned on an account
x------> the balance in the account
step 1
Find the constant k of proportionality
For 
substitute the values
The equation is
step 2
Find the amount of interest earned on an account with a balance of $500
so
For 
substitute in the equation and solve for y
Oooh I miss these. Haven't done them since kindergarten! 24/25 would equal 0.96. 87+0.96 would get 87.96. 7/10 is 0.7 so 224+0.7=224.7. 49/50 is 0.98, so 0.98+686 is 686.98.
