Answer:

<em>y</em> = 6

Step-by-step explanation:

The red square represents a 90 degree angle. If you subtract 36 from 90 you will get 54. Then to find <em>y</em>, divide 54 by 9 and you get 6.

Hope this helped!!  :)

GalinKa [24]

Answer:

  ∠A = 26°

Step-by-step explanation:

Supplementary angles total 180°.

  ∠A +∠B = 180°

  (x -16)° +(3x +28)° = 180°

  4x° + 12° = 180°

  x° +3° = 45°

  x° = 42°

  ∠A = (x -16)° = 42° -16°

  ∠A = 26°

A wide receiver catches a ball and begins to run for the endzone following a path defined by . A defensive player chases the rec
postnew [5]

Answer:

Receiver path:

x-5 = t(0)

y-50 = -10t

defender path:

x-10 = -0.9t

y-54 =-10.72t

Yes, he will reach the goal line (y = 0) before the defensive player catches him.

Step-by-step explanation:

Vector equation: (x-x1, y-y1) = t(a1, a2)

Horizontal component : x-x1= ta1

Vertical component: y-y1= ta2

(x-5, y-50) = t(0, -10)

x-5 = t(0)

y-50 =t(-10)

Parametric equation for the receiver path:

x-5 = t(0)

y-50 = -10t

(x - 10, y - 54) = t(-0.9, -10.72)

x - 10 = t(-0.9)

y - 54 = t(-10.72)

Parametric equation for the defender path:

x-10 = -0.9t

y-54 =-10.72t

At the 50yard line, using the receiver parametric equation for vertical component:

y-50 = -10t

At y= 50

50-50 = -10t

0= -10t

t= 0/-10 = 0

At y= 0

0-50 = -10t

t = -50/-10 = 5

Defender at y = 50

y-54 =-10.72t

50-54 =-10.72t

t = -4/-10.72 = 0.37

at y = 0

0-54 =-10.72t

t = -54/-10.72 = 5.04

t of receiver < t of defender

Since time of receiver at y=0 is less than time of defender, he will reach the goal line (y = 0) before the defensive player catches him.

In a survey of 2300 people who owned a certain type of​ car, 1035 said they would buy that type of car again. What percent of th
vivado [14]

Answer:

45%

Step-by-step explanation:

1. We assume, that the number 2300 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 2300, so we can write it down as 100%=2300.

4. We know, that x% equals 1035 of the output value, so we can write it down as x%=1035.

5. Now we have two simple equations:

1) 100%=2300

2) x%=1035

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=2300/1035

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1035 is what percent of 2300

100%/x%=2300/1035

(100/x)*x=(2300/1035)*x       - we multiply both sides of the equation by x

100=2.2222222222222*x       - we divide both sides of the equation by (2.2222222222222) to get x

100/2.2222222222222=x

45=x

x=45
