Find the missing number <br><br>5,_,10,12 1/2<br><br>11.5,9.4,

Korolek [52]

Answer:

H

Step-by-step explanation:

Let represent A and B

A and B is the sum of the first 50 consecutive multiples of 3 and 6, this is the same as a arithmetic sequence because arithmetic sequences have a common sum.

We can represent this as

$a _{n} = a {}^{1} + d(n - 1)$

where a^1 is the first term, d is the common sum, n is the number of multiples we adding.

The first term for both A and B respectively is 3 and 6.

Multiples implies that the Difference between A and B are 3 and 6 respectively. There are 50 consecutively. multiples.

Plug in the known parts for both.

$3 + 3(49) = 150$

$6 + 6(49) = 300$

We need to what percent of find 150% of 300.

B is twice as A, so this means that we need to multiply 2 by it original or 100% of it self.

$2 \times 100 = 200$

So 200% is the answer.

How do you determine two angles which are coterminal to the given angles ?

Julli [10]

Answer:

Coterminal Angles are angles who share the same initial side and terminal sides. Finding coterminal angles is as simple as adding or subtracting 360° or 2π to each angle, depending on whether the given angle is in degrees or radians. There are an infinite number of coterminal angles that can be found.

Step-by-step explanation:

i hope this helped you :)

Find an equation of the line that is perpendicular to the graph of 2x+5y=5 and contains the point of intersection of the graphs

gavmur [86]

Answer:

5(x+1) -2(y-3) = 0

Step-by-step explanation:

For a given line ax+by=c and point (h, k), a perpendicular line through the point can be written as ...

b(x-h) -a(y-k) = 0

A graphing calculator shows the point of intersection of the graphs of the two lines to be (x, y) = (-1, 3), so the line perpendicular to 2x+5y=5 through that point can be written ...

5(x+1) -2(y-3) = 0

_____

In the attached graph, the requested line is shown in black.
