The required expressions are both equations 1 and 2 as shown:

s + t = 90 ......... 1

t .... 2

Complementary angles are angles that sum up to 90 degrees. For instance, and A and B are complementary if A + B = 90.

According to the question, if two complementary angles have measures of s and t then:

s + t = 90 ......... 1

Twice of 's' is expressed as 2s

If t is less than twice s, this can be expressed as t .... 2

The required expressions are both equations 1 and 2 as shown:

s + t = 90 ......... 1

t .... 2

Write the standard equation of the circle with center (-14, -3) that passes through the point (-5,3),
grin007 [14]

Answer:

(x + 14)^2 + (y + 3)^2 = 117

Step-by-step explanation:

Equation of a circle:

The equation of a circle with center (x_0,y_0) is given by:

(x - x_0)^2 + (y - y_0)^2 = r^2

In which r is the radius.

Center (-14, -3)

This means that x_0 = -14, y_0 = -3

So

(x - x_0)^2 + (y - y_0)^2 = r^2

(x - (-14))^2 + (y - (-3))^2 = r^2

(x + 14)^2 + (y + 3)^2 = r^2

Passes through the point (-5,3),

This means that when x = -5, y = 3. We use this to find the radius squared. So

(x + 14)^2 + (y + 3)^2 = r^2

(-5 + 14)^2 + (3 + 3)^2 = r^2

r^2 = 117

So, the equation of the circle is:

(x + 14)^2 + (y + 3)^2 = r^2

(x + 14)^2 + (y + 3)^2 = 117

Divide 33 photos into 2 groups so the ratio is 4 to 7
lapo4ka [179]
First you'll need two equations ( you can use any variables you want)
A= photo group 1
B= photo group 2
First equation:
A + B = 33
This is because the total number of photos from both groups is 33
Second equation:
4A = 7B
This is because the ratio is 4:7 so for every four photos in group A there must be 7 photons in group B.
Then take the first equation A + B = 33 and subtract B from both sides. Making the equation A = 33 - B
Then with that equation, substitute it in for equation 2 and it will look like this. 4(33-B) = 7B
Then distribute the 4 to the 33 and the -B making the equation 132 - 4B = 7B
Then add 4B to each side
Making the equation 132 = 11B
Then to get B by itself you must divide each side by 11 making the equation 132/11 = B which simplifies to 12 = B
Then plug in 12 for B in the first equation like this A + 12 = 33
Then subtract 12 on each side of the equation to isolate A so A = 21

So
A = 21
B = 12
