There is 180deg in a half circle, and 360deg in a full circle. complementary angles complete a half circle perfectly.
angle z is complementary to 111deg.
z= 180 - 111= 69deg
z= 69deg
There are 360 total degrees in the figure because it makes one total revolution.
y= 360- 69- 94- 88
y= 109deg
Check - 109 +69 +94 +88= 360
Multiply the amount he sold by the percent of commission:
4500 x 0.13 = 585
he made $585 last week.
There are 52 weeks in a year, multiply the amount of commission by 52:
585 x 52 = 30,420
he made $30,420 in 2011.
2 and 1/2 (or 5/2) minus 1/3 equals 13/6 or 2 and 1/6
So, the answer is 13/6 OR 2 1/6
Answer:
A) x = 7
Step-by-step explanation:
7x + 1 + 7x + 6 + (180° - 15x) = 180°
14x + 7 + 180° - 15x = 180°
combine like terms:
-x = -7
x = 7
Answer:
2069
Step-by-step explanation:
We can set up an exponential equation to track the number of students at any year
Mathematically, that will be;
y = I(1 + r)^t
where y is the population at any year
r is the percentage increase per year which is 4% = 4/100 = 0.04
t is the number of years from 2018 = 2025-2018 = 7
I is the population in 2018 = 1572
Thus, we have;
y = 1572(1 + 0.04)^7
y = 1572(1.04)^7
y = 2,068.645 which is approximately 2,069
