Answer:
4/5x+2/5 = y
Step-by-step explanation:
(-3, -2) & (2,2) - given points
1. Find Slope
2-(-2) / 2-(-3) = 4/5
m=4/5
2. plug in points to find b
4/5(x)+b=y : mx+b=y (slope intercept form)
4/5(2)+b=2
8/5+b=2
2 - 8/5 = b
10/5 - 8/5 = b
b=2/5
Therefore: 4/5x + 2/5 = y

Caroline, Colin & Sarah share some money.
Caroline gets 19 of the money.
Colin and Sarah share the rest in the ratio 3:1.
What proportion does Sarah get?
Answer:
I think you mean 1/9.
If so, Sarah gets 2/9 of the money.
Step-by-step explanation:
1 = 9/9
1-(1/9)= 8/9
Colin : Sarah, altogether is 8
6 : 2
Thus, Sarah get 2/9

Sarah proportion is 25% of the momey
A fire ranger on a 150-ft-tall tower spots a fire at a 30° angle of depression. How
many feet away from the tower is the fire to the nearest tenth?
Answer:
259.8ft
Step-by-step explanation:
The distance from the tower to the fire to the nearest tenth is 260 feet.
Let the adjacent side be a.Given the following data:
Angle of depression = 30°.Opposite side = 150 feet.To determine how far away (in feet) from the tower is the fire to the nearest tenth:
How to apply trigonometric function.In order to solve this exercise, we would form a mental image of the scenario being described. The height of the tower is the opposite side while the distance from the tower to the fire is the adjacent side.
Next, we would apply the Tan trigonometric function:
[tex]Tan \theta = \frac{Opp}{Adj} \\\\Tan 30=\frac{150}{a} \\\\a=\frac{150}{Tan 30} \\\\a=\frac{150}{0.5774}[/tex]
a = 259.79 ≈ 260 feet.

Years since 2010 0 1 2 3 4 5 Profit (dollars) 39,000 84,000 111,000 120,000 111,000 84,000 Which of the following statements is true for this situation? O A. Since the profit made in 2011 is equal to the profit made in 2015, the profit is symmetric about the line x= 4. O B. Since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y= 120,000. OC. The profit is not symmetric. OD. Since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line x= 3.

if a person walks 1/3 a mile in each 1/2 hour, how far does he walk in 1 hour.
Distance travelled in 30 minutes = 1/3 miles
Distance travelled in 1 minute = 1/(3 × 30)
Distance travelled in 60 minutes = (1 × 60)/(3 × 30)
= 2/3 miles
find the geometric mean between 12 and 20 find the answer in radical form
Answer:
4√15
Step-by-step explanation:
The geometric mean of x and y is √(xy).
So here we have:
√(12*20)
= √240
= √(16*15)
= √16√15
= 4√15.
Parker and Eugene sold tickets for the school play.They each need to sell 35 tickets To receive a prize. On day one sold 23 tickets on day two sold 25 tickets and on day three the sold 35 tickets if they want to equally share the number of tickets between them how many ticket sales will each boy have

On a math test, Rosie answered 36 questions correctly, which was 72%. how many questions were on the test?
Answer:
50
Step-by-step explanation:
What I did first is I converted 72% into a decimal (I work better with decimals), giving me 0.72. Then I solved the equation 36/0.72=x.
x = 50
Answer:
50 questionsStep-by-step explanation:
Let the number of questions be x.
We have:
72% of x is 36.Build an equation and solve for x:
0.72x = 36x = 36/0.72x = 50divide 96m into two part

Supplementary means the angels add up to 180 degrees. So 95 + ? = 180. The ? is equal to 85, but how do you get it. Well we know 5x means to multiply a # by 5. So 17 x 5 = 85. So x = 17. Hope this helps!
Answer:
17
Step-by-step explanation:
5 x 17 = 85 right?
95 + 85 = 180.
