Answer:the total cost of taming 10 flute lessons is 310
Step-by-step explanation:
The equation to determine f, the total cost of flute lessons is expressed as
f = 25m + 60
Where
m represents the number of months of lessons she would take.
Jess decides to take flute lessons for 10 months. Therefore, the total cost of taming 10 flute lessons would be
f = 25 × 10 + 60
f = 250 + 60
f = 310
Given:
length 30 inches
k = 24
v = l * w * h
volume varies directly w/ the length: v = kl
v = 24 * 30 = 720
k = wh
24 = wh
w = 24/h or h = 24/w
P = 2w + 2h
20 = 2w + 2h
20 = 2(24/h) + 2h
20 = 48/h + 2h
48/h + 2h - 20 = 0
h(48/h + 2h - 20) = 0
48 + 2h² - 20h = 0
2h² - 20h + 48 = 0
2(h² - 10h + 24) = 0
2(h - 6)(h - 4) = 0
h = 6 or h = 4
Since the height serves as the length in the perimeter equation, then its measure is 6 and width is 4.
length = 30 ; width = 4 ; height = 6.
Answer:
1 = 26
2 = 154
3 = 26
4 = 26
5 = 154
6 = 26
7 = 154
Step-by-step explanation:
1 = 180 - 154 = 26
2 = 154
3 = 1 = 26
4 = 180 - 2 = 180 - 154 = 26
5 = 180 - 4 = 180 - 26 = 154
6 = 5 = 154
7 = 4 = 26
Answer:
They intersect
Step-by-step explanation:
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel.
Here we have two functions:
1) y = 4x + 2
2) 8x + 2y = - 3
2y = - 8x - 3
// divide both sides by 2
y = - 4x - 1,5
- 4 ≠ 4 , so these lines aren't parallel, maybe you wrote the assignment incorrect (e. g. if there would be " - " before 8 in the second function, those lines would be parallel), here they intersect.
