A senior employee who works 16 hours earns $39.50 more than a junior employee who works 18 hours. The senior employee earns $14 per hour. What is the hourly pay for the junior employee in dollars and cents?
(IN A TEST)
Answer:hourly pay for the junior employee in dollars and cents=$10.25
Step-by-step explanation:
Step 1
Total amount senior employee is being paid = amount per hour x hours worked
= $14 × 16 = $224.00
Total amount of junior employee since he/ she collects $39.50 less than senior employee= $224.00 - $39.50
= $184.50
Step 2
hourly pay of junior colleague= Total pay of junior colleague/ Hours worked
=$184.50 / 18 hours
= $10.25 per hour
Simplify the expression 4(5 - 2)2 – 7.
Answer:
17
Step-by-step explanation:
Remember to solve by the order by operations, or PEMDAS. PEMDAS says that when simplifying an expression, you need to solve parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right) in that order.
1) Knowing this, start by solving what's in the parentheses:
[tex]4(5-2)2-7\\= 4 (3)2-7[/tex]
2) Then - still following the order of operations - multiply the 4, 3, and 2 together.
[tex](4)(3)(2)-7\\(24)-7[/tex]
3) Finally, subtract 7 from 24.
[tex]24-7\\= 17[/tex]
Therefore, 17 is the answer.

Answer:
-2 due to the y axis having the line run through the -2
Answer:
Y-intercept is -2. Equation is y=1x-2
Step-by-step explanation:
#NotATest.
You probably don't want an explanation.
The y-intercept is -2 because that is where the line meets the y-axis.
The slope is 1 because the line is going up 1 unit, and over 1 every time.
The last part is -2 because that is the y-intercept.

an object dropped from a height of 210ft will fall according to the equation h(t) =210-16t^2. how long will it take the object to reach the ground
Answer:
[tex]\sqrt{210/16}[/tex]
Step-by-step explanation:
By saying reach the ground, it means the altitude w[tex]\sqrt{}[/tex]ill be zero, so the equation will be: 210 - 16t^2 = 0
210 = 16t^2, t = [tex]\sqrt{210/16}[/tex]
