7. A garden contains 284 flowers, each of which is either red or yellow. There are 5 beds of yellow flowers and 4 beds of red flowers. There are 40 yellow
flowers in each yellow flower bed. If r represents the number of red flowers in
each red flower bed, what equation could you use to represent the number of
red and yellow flowers?

284=5(40)+4r

Step-by-step explanation:

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
