Answer:
A, B, C, F
Step-by-step explanation:
A: Its is acute because it has 2 sides that are less than 90%
B: It is obtuse because there is 1 side that is over 90%
C: It has 2 equal sides.
F: 100% + 40% + 40% = 180%
Answer:
Step-by-step explanation:
<u>Variable: </u>
<u>Equation:</u>
<u>Solution:</u>
- 5(3p + 0.97) = 12.89
- 15p + 4.85 = 12.89
- 15p = 12.89 - 4.85
- 15p = 8.04
- p = 8.04 / 15
- p = 0.536
Hi!
First, let me explain that open circles mean that the answer starts after or before that number. So if the answer is q < 4, the answer would be C, and not B.
If the answer was q ≤ 4, the answer would be B, and not C.
I hope that makes sense. Now let's solve the inequality.
Remember that whatever we do to the inequality, we have to do it to both sides.
We need to isolate q on one side.
11q + 5 ≤ 49
Start by subtracting 5 from both sides.
11q + 5 - 5 ≤ 49 - 5
11q ≤ 44
Divide by 11 on both sides.
11q/11 ≤ 44/11
q ≤ 4
The answer is B.
Hope this helps! :)
Step-by-step explanation:
$800 × 5% = $40
for 1 year, I earn $40
100 ÷ 40 = 2 remainder 2
Therefore I would have to leave the money in for at least 3 years to earn $100
Answer:
19
Step-by-step explanation:
the value of f(x) = 2x^2 + 1, for x = 3
f(3) = 2×3^2 + 1➡ 2×9 +1= 19
