Answer: 23

Step-by-step explanation:

Since we have Pemdas, we can rewrite the thing like 8 + (6/2) + 12. Now we get 8 + 3 + 12 = 23

Corey stepped back 59.71 feet to get a better view of the bird.

Explanation:

This is a right angled triangle. Let \theta be the angle of elevation.

Let the adjacent side of the triangle be x for the angle \theta

Let the opposite side of the triangle by y for the angle \theta

Thus,

\tan \theta=\frac{y}{x}

Since, the height of the tree is 80 feet, y=80

To find the value of x, let us substitute y=80 and \theta=68

x=\frac{80}{\tan 68^{\circ}}=32.32

Since, Corey moves back a few steps to gain a better view of the bird, the angle of elevation is 41°

Now, we shall find the x for  y=80 and \theta=41

x=\frac{80}{\tan 41^{\circ}}=92.03

To find how many feet Corey step back is to subtract the value of two adjacent sides, thus,

x=92.03-32.32=59.71

Thus, Corey stepped back 59.71 feet to get a better view of the bird.

4y+12=7-5y, plz can u tell me how u worked it out plz thx :)
IrinaVladis [17]
4y+12=7-5y  add 5y to both sides

9y+12=7  subtract 12 from both sides

9y=-5  divide both sides by 9

y=-5/9

Write an equation of the line in point-slope form that passes through the given points.
RSB [31]

Answer:

Step-by-step explanation:

point - slope  formula:  y - y1 = m(x-x1)

we need to find the slope ... or what is m ?

m = rise / run  

m = y2 - y1  / x2 - x1    

where the given points are  (x1,y1)  and (x2,y2)

m= 7-5 / 6-5

m = 2 / 1

m =2

now use either point and plug the slope and the point into the point-slope formula

y-5 =2(x-5)     :)

2. 15-8=7, now you only have 7

3. last, since you only have 7 then it is 1 whole and 7 8ths
