Answer:
1.5 or 1/5
Step-by-step explanation:
Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.

Interest = 3,960,000
Triangle ABC is an acute triangle. Two sides measure 5 and 7. What is the range of possible values for its third side?
Answer:
the desired range is 2 < t < 12.
Step-by-step explanation:
If the third side is 12 (the sum of 5 and 7), we don't really have a triangle, since the 5-unit and 7-unit sides add up to 12 and lie on the third side (of length 12).
Since triangle ABC is acute, all its angles are between 0 and 90 degrees. So the third side can be 12 but not greater. The smallest possible length of the third side is 2, since 5 + 2 = 7.
Thus, the desired range is 2 < t < 12.

(8x2 – 7x – 2) – (6x2 – x + 3)
Answer:
2 x² - 6x -5
Step-by-step explanation:
Expansion:-
Given that the expression
(8x²-7x-2)-(6x²-x+3)
= 8x² - 6x² - 7x +x -2 -3
= 2 x² - 6x -5

Find the sum of the measures of the interior angles of the indicated convex polygons.
1. 17-gon
2. 24-gon
Answer:
1. 17 - gon
sum of the of measures of interior angles = 180(n-2).....(formula)
here n = 17
therefore, 180(17-2)
= 180(15)
= 2700 degrees
2] 24 - gon
sum of the of measures of interior angles = 180(n-2).....(formula)
here n = 24
therefore, 180(24-2)
= 180(22)
= 3960 degrees.
In a poll to pick the name of a new planet discovered in a distant solar system, a total of 963 scientists voted. There were four names to pick from. The winning name exceeded the other names by 53, 79, and 105 votes, respectively. How many scientists voted for the name which came fourth in the poll?
Answer:
195
Step-by-step explanation:
Let wining name have, x votes
1st = x
2nd = x - 53
3rd = x - 79
4th = x - 105
x + (x - 53) + (x - 79) + (x - 105) = 963
x + x - 53 + x - 79 + x - 105 = 963
4x - 237 = 963
4x = 963 + 237
4x = 1200
x = 1200 / 4
x = 300
4th = x - 105
x - 105 = 300 - 105 = 195
Sansa shifted the parabola y = x^2 by 3 units to the right. Which of the following equations corresponds to the resulting graph?
А) y = x2 + 3
B) y = x2 + 9
C) y = x2 + 6x + 9
D)y = x2 - 6x + 9
Answer:
y = (x - 3)^2
Step-by-step explanation:
The original function is y = x^2. Its vertex is at (0, 0). Translating the graph h units to the right results in g(x) = (x - h)^2; h units to the left results in h(x) = (x + h)^2.
In this particular case we have y = x^2 and are translating the graph 3 units to the right. Thus, the original function y = x^2 becomes y = (x - 3)^2.

Answer:
26
Step-by-step explanation:
With some trial and error I found out that the square equals 5 and the circle equals 7. Now to find the triangle, I used the second equation. It was ⬜+⭕+⭕+⛛+⛛ = 27
So I put in the numbers in place of the square and circle:
5+7+7+⛛+⛛ = 27
5+7+7 = 5+14=19
27-19=8
So now we know that 2⛛=8
So I did 8 ÷ 2 = 4. ⛛=4
So we know that ⛛ = 4, ⭕ = 7, ⬜ = 5
Lets solve: ⬜ + ⬜ + ⬜ + ⭕ + ⛛ = ?
Translating into: 5 + 5 + 5 + 7 + 4 = 26
So our final answer is 26.
Write the numbers in order from least to greatest.
