Answer:

35.8°

144.2°

Step-by-step explanation:

Definition of Supplementary Angles: They add up to 180°

Step 1: Set up equation

3x + 12x + 1 = 180

Step 2: Solve

15x + 1 = 180

15x = 179

x = 11.93

Step 3: Find angles

∠1 = 3x

m∠1 = 3(11.93) = 35.8°

∠2 = 12x + 1

m∠2 = 12(11.93) + 1 = 144.2°

nordsb [41]

Answer:

  1.5 seconds

Step-by-step explanation:

The height equation is supposed to be ...

  h(t) = -16t^2 +22t +3

We want to find the positive value of t where h(t) = 0.

  0 = -16t^2 +24t -2t +3 . . . . facilitate factoring

  0 = -8t(2t -3) -1(2t -3) . . . . . factor by pairs

  0 = -(8t +1)(2t -3) . . . . . . . .  complete the factoring

The solutions to this are ...

  t = -1/8, 3/2

The ball will reach the ground in 1.5 seconds.

A rule for creating a pattern is given below.
STALIN [3.7K]

Answer:

Choice B

Step-by-step explanation:

This is shown by following the simple multiplication rule that has been set, which is x*6=y. By doing this, we get:

Choice A: 1 * 6 = 6

Choice B: 2 * 6 = 12

So as you can see, choice A would be incorrect, and choice B would be correct.

Emma took 35 pictures of flowers on a nature walk and an additional 3 pictures of each bird she saw. She took a total of 83 pict
DedPeter [7]
83 = 3x + 35

The total number of pictures taken is 83, so the equation is equal to 83.
The word <em>each</em> indicates that the variable will be multiplied. Since Emma takes 3 pictures for <em>each </em>bird she saw, 3x will indicate the number of bird pictures taken. 
35 flower pictures have already been taken, so this value is added to the number of bird pictures Emma took.
