Answer:
50
Step-by-step explanation:
A triangle has 180 degrees. Since the square shows a right angle, and we already have the 40 value, we just add 40+90, which is = to 130. We then subtract 130 from 180, getting 50.

<u>Answer:</u>
The correct answer option is H. 4374.
<u>Step-by-step explanation:</u>
We are given the following geometric sequence and we are to find its 8th term:
Here and common ratio .
The formula we will use to find the 10th term is:
nth term =
Substituting the values in the formula to get:
10th term =
10th term = 4374
Answer:
x = 1
Step-by-step explanation:
The easiest way to solve this is to graph it.
f(x) = 2^x + 1
g(x) = -x + 4
just reading the graph, the intersect point is (1,3).
- Red: f(x)=2^x + 1
- Blue: g(x) = -x + 4
I cannot see any simple way of doing this other than by graphing.
Answer x = 1
Answer:
140
Step-by-step explanation:
When working HCF and LCM problems, I like to think in terms of this little diagram:
(a [ b ) c]
It shows me one of the numbers is ab, the other is bc, the HCF is b and the LCM is abc. "a" and "c" must be relatively prime for "b" to be the HCF.
__
Here, we're given ...
b = 20
ab = 320
abc = 2240
Then ...
c = abc/(ab) = 2240/320 = 7
x = bc = 20(7) . . . . . . equivalently, x = (abc·b)/(ab) = (2240·20)/320
x = 140
