Answer:
X
Step-by-step explanation:
Let X is the number of hours Larry works a day
Given: Larry spends half of his workday teaching piano lessons.
=> Number of hours he teaches piano a day is: X
As we know that, he has 6 students, so the fraction of his workday is spent with each student is:
X : 6
= X
Hope it will find you well during the time of isolation.
There are two equal sides of 8, which means this is an isosceles triangle. With an isosceles triangle, there are also two equal angles (30° each in this case). If angle C equals 30°, then angle B also equals 30°. Subtract angles B and C from the total degrees in a triangle.
Triangles Degrees= 180° total
Find angle A:
= total triangle degrees - < B - < C
= 180° - 30° - 30°
= 120°
ANSWER: Angle A is (B) 120°
Hope this helps! :)
To find that one, just look at the highest exponent. In the given equation that would be 4, so there can be at most 4 zeros in this function.
-5.55 - 8.55c + 4.35c
-8.55c + 4.35c = -4.2c
-5.55 - 4.2c is the answer.
Answer:
Rate when price rises 20% = $36
Rate when price downs 20% = $24
Step-by-step explanation:
Given:
Current rate to mow = $30 per lawn
Find:
Rate when price rises 20%
Rate when price downs 20%
Computation:
Rate when price rises 20%
Rate when price rises 20% = Current rate to mow + 20%[Current rate to mow]
Rate when price rises 20% = 30 + 20%[30]
Rate when price rises 20% = 30 + 6
Rate when price rises 20% = $36
Rate when price downs 20% = Current rate to mow - 20%[Current rate to mow]
Rate when price downs 20% = 30 - 20%[30]
Rate when price downs 20% = 30 - 6
Rate when price downs 20% = $24
