Answer:
Based on your line, what is the likely test score of a student who does not study for the test? 45
1) 7 hours and 33 minutes
2) 28
3) y = 7
4) a times a times a times a
Answer:
expression: 3(d+35)
simplified expression: 3d + 105
Step-by-step explanation:
The first drone costs d. This means the expression = d
The second drone costs d and an additional $35. Expression = d + 35
The third drone costs 3 times as much as the previous one. Expression = 3(d+35)
To simplify it, you just distribute. Hope this helps :)
This is a system of equations problem.
L = Hours of Swim Lessons
C = Hours as Cashier
L + C = 15 This is an equation for working 15 hours total.
so
L = 15-C
6L + 8C = 100 This is an equation for making at least $100.
so
6 (15-C) + 8C = 100 *You substituted 15-C for L here
90 - 6C + 8C = 100 Distribute
90 + 2C = 100
2C = 10
C = 5 You can work 5 hours as a cashier
L + C = 15
L + 5 = 15
L = 10 You can work 10 hours teaching swimming lessons.
If you want to make EXACTLY $100 you would work 5 hours as cashier and 10 hours teaching swimming lessons.
HOWEVER, the question says AT LEAST $100 and NOT MORE than 15 hours per week. Since you make more money as a cashier, any work over 5 hours will help you make over $100.
As long as you work at least 5 hours as a cashier and any remaining hours teaching swimming lessons, you will make over $100.
5 cashier, 10 swimming
6 cashier, 9 swimming
7 cashier, 8 swimming...

The circumference of the pool is 26.38 meters
<h3>How to determine the circumference?</h3>
The radius, r is given as:
r = 4.2
The circumference, C is calculated using:
This gives
C =2 * 3.14 * 4.2
Evaluate
C = 26.38
Hence, the circumference of the pool is 26.38 meters
