Answer:
= 0.00334
therefore,
3,872.80 > 0.00334
Step-by-step explanation:
Which statement is correct?
(2.06x102x1.88 x 10-1) <7.69x 10
2.3x10-5
(2.06 x 10-2)(1.88 x 10-1) 7.69x 10-
2.3x10-5
7.69 x 10"
(2.06 x 10-2x1.88x10-)>
2.3x10-5
(2.06x 10-2X(1.88x 10-1)-7.69x104
2.3x10-5
Given that;
= 0.00334
therefore,
3,872.80 > 0.00334
Answer:
213 degrees
Step-by-step explanation:
A quadrilateral has an internal measurement of angles of 360 degrees. Given that we have 3 measures of the angles, we simply need to find the 4th. This can be accomplished with the following equation:
x + 52 + 54 + 41 = 360
x + 52 + 95 = 360
x + 147 = 360
x = 213
Hence, the measure of the final angle is 213 degrees.

Answer:
21
Step-by-step explanation:
In order to form a chord you need to:
- Select one point. You have 7 choices
- Select a another point. You have just 6 choices because you have to dicard the point alredy chosen
- Connect the two points with a chorde
Since we have 7 choices for the first point and 6 for the second one, one might think that there are a total of 7*6 = 42 choices.
However the correct answer is 21, because you have to take into the account that selecting the point A first and selecting the point B on second step is the same than selecting the point B first and then the point A, because the chord is the same.
Therefore we are counting each chord twice, and we have to divide the result by 2, obtaining 7*6 / 2 = 21.
You can also calculate the amount by using the combiatorial number. The total amount of possibilities to select k elements from a set of n, with n higher than or equal to k and both positive, without taking into account the order is the combinatorial number of n with k, given by
In this case, in order to form a chord we need to select 2 points of the seven we are given, ignoring order, thus the total amount of possibilities is
As we calculated before.
The correct answer is A. 2cm
18 2cm
---- = ----
45 5cm
hope this helps
Answer:
The number is 80
Step-by-step explanation:
The question in English is
The excess of one number over 20 equals three quarters of the same number. What is the number?
Let
x ------> the number
we know that
The linear equation that represent this situation is
Solve for x
therefore
The number is 80
