Answer:
6=100°
8=80°
7=100°
9=80°
Step-by-step explanation:
If 6 is 100°
in a straight line theres 180 degrees
180-100=80°
8 is 80°
opposite 6 to 7 there are parallel corresponding angles meaning the angle opposite it will be the same. 8 with 9.
same with
Answer:
360 - Y
Step-by-step explanation:
From the information provided in the question, we will understand that the question lacks detailed information.
Given that:
The total number of actual students on the A honor roll = 360
To find the number of students on the A honor roll of 8th graders;
Let denote Y to represent the total number of students who exist on the A honor roll except for the 8th graders.
Then:
The number of 8th graders = all number of students on are on the A honor roll - Y
The number of 8th graders = 360 - Y
If Y is known, then the number of the 8th graders can be fully determined.
Answer:
2201.8348 ; 3 ; x / (1 + 0.01)
Step-by-step explanation:
1)
Final amount (A) = 2400 ; rate (r) = 6% = 0.06, time, t = 1.5 years
Sum = principal = p
Using the relation :
A = p(1 + rt)
2400 = p(1 + 0.06(1.5))
2400 = p(1 + 0.09)
2400 = p(1.09)
p = 2400 / 1.09
p = 2201.8348
2.)
12000 amount to 15600 at 10% simple interest
A = p(1 + rt)
15600 = 12000(1 + 0.1t)
15600 = 12000 + 1200t
15600 - 12000 = 1200t
3600 = 1200t
t = 3600 / 1200
t = 3 years
3.)
A = p(1 + rt)
x = p(1 + x/100 * 1/x)
x = p(1 + x /100x)
x = p(1 + 1 / 100)
x = p(1 + 0.01)
x = p(1.01)
x / 1.01 = p
x / (1 + 0.01)
Answer:
1) solve x+1/x = 5
2) solve x³+1/x³
substitute x = 1/4 into the expression
