Answer:
The cost of lesson for 9 hours on weekdays and 3 hours on weekends
Step-by-step explanation:
Given
Required
What does 9m + 3(1.2m) represent
The expression can be split to:
9m and 3(1.2m)
<u>For 9m:</u>
From the question, we understand that:
Multiply both sides by 9
This means that:
9m = the cost of lessons for 9 hours on weekdays
<u>For 3(1.2m):</u>
From the question, we understand that:
Multiply both sides by 3
This means that:
3(1.2m) = the cost of lessons for 3 hours on weekends
Hence, the expression represents:
The cost of lesson for 9 hours on weekdays and 3 hours on weekends
The answer should be the 3rd one
Answer:
Not sure if this is right, but I got $40.8.
Step-by-step explanation:
I first turned 20% into a decimal. (0.20).
Then I multiplied 0.20 and 34 which is 6.8.
I then added 34 since it’s the original cost to 6.8 since that’s the tip amount.
After that, you should get $40.8.
Answer:
(a) x = 30°
(b) mRS = 30°
mST = 120°
mTU = 120°
mUR = 90°
Step-by-step explanation:
(a) In the picture attached, the diagram is shown.
Given that m arc RS = x, from the ratios:
m arc ST = 4x
m arc TU = 4x
m arc UR = 3x
The addition of the four arcs must be equal to 360°, then:
x + 4x + 4x + 3x = 360°
12x = 360°
x = 360°/12 = 30°
(b) m arc RS = x = 30°
m arc ST = 4x = 4*30° = 120°
m arc TU = 4x = 4*30° = 120°
m arc UR = 3x = 3*30° = 90°
