Answer:
He is 5.6 km away
Step-by-step explanation:
he starts traveling away from base and is 8.3 km away to start with
then he turns west and travels 13.9 km away
what this mean is that you have to subtract the distance he turned from the distance he started off with
ex: 13.9 - 8.3 = 5.9
to get your answer of how far away he is from the base

Find the equation of the line that
is perpendicular to y = –
-x and
contains the point (4,-8).
y=
x + [ ]
Answer:
y = 3x/2-14
Step-by-step explanation:
We are given that the line is perpendicular to y = -2/3 and contains (4,-8).
Perpendicular Def.
[tex] \displaystyle \large{m_1m_2 = - 1}[/tex]
Both slopes multiply each others equal to -1.
Finding another slope that is perpendicular to -2/3, substitite m1 = -2/3 in.
[tex] \displaystyle \large{ - \frac{2}{3} m_2 = - 1}[/tex]
Multiply both sides by 3.
[tex] \displaystyle \large{ - \frac{2}{3} m_2( 3) = - 1(3)} \\ \displaystyle \large{ - 2 m_2= - 3} \\ \displaystyle \large{ m_2= \frac{3}{2} }[/tex]
Therefore, another slope that is perpendicular to -2/3 is 3/2.
Then rewrite in slope-intercept form.
Slope-Intercept
[tex] \displaystyle \large{y = mx + b}[/tex]
where m = slope and b = y-intercept; substitute m = 3/2 in.
[tex] \displaystyle \large{y = \frac{3}{2} x + b}[/tex]
Since the line contains (4,-8), substitute x = 4 and y = -8 in and solve for b.
[tex] \displaystyle \large{ - 8 = \frac{3}{2} (4) + b} \\ \displaystyle \large{ - 8 = 3(2)+ b} \\ \displaystyle \large{ - 8 = 6 + b} \\ \displaystyle \large{ - 8 - 6 = b} \\ \displaystyle \large{ - 14 = b}[/tex]
Therefore, b is -14; rewrite again in slope-intercept form.
Thus:-
[tex] \displaystyle \large{y = \frac{3}{2} x + b} \\ \displaystyle \large{y = \frac{3}{2} x - 14}[/tex]

Find the measure of the missing angle.
Answer:
34
Step-by-step explanation:
if you add 90+56 you get 146 and then 180-146=34
Answer:
a = 34°
Step-by-step explanation:
1. We know that the straight line is a straight angle (180°), and the right angle is worth 90°.
2. This means that a + 90 + 56 = 180.
3. (Solving equation above).
Step 1: Simplify both sides of the equation.
[tex](a)+(90+56)=180[/tex] [tex]a + 146 = 180[/tex]Step 2: Subtract 146 from both sides.
[tex]a+146 - 146 = 180 - 146[/tex] [tex]a = 34[/tex]Step 3: Check if solution is correct.
[tex](34) + 90 + 56 = 180[/tex] [tex]124 + 56 = 180[/tex] [tex]180 = 180[/tex]Therefore, a = 34°.
A gym employee earns the same amount each month. After working for three months, he earned $4,500. Complete the table to determine how much money he will make over a five-month period. on. 8.If his pay rate remains the same, how much will he earn after working 7 months?
Answer:
Each month he earn $1,500 a month because $4,500 divided by 3 is $1,500. So in 5 months he will make $7,500. On the 7th month he will have $10,500.
The money that the gym employee earns in 1 month will be; $1500. The money that the gym employee earns in 5 months will be; $7500.
How to calculate the value?The gym employee earns the same amount each month and after working for three months, he earned $4,500.

Answer:
[tex]y=\frac{-1}{3} x+4[/tex]
Step-by-step explanation:
Use the equation, [tex]y=mx+b[/tex].
'[tex]m[/tex]' will be your [tex]\frac{rise}{run}[/tex], or the slope of the equation.
'[tex]b[/tex]' is the y-intercept of the line or basically where the line touches the y axis.
The line touches the y-axis at y=4, so '[tex]b[/tex]' will be 4.
To figure out the '[tex]m[/tex]' value, count how many squares the line moves over and then how many squares it moves down. In this case, it moves down 1 square and over three squares. So the [tex]\frac{rise}{run}[/tex] will be [tex]\frac{-1}{3}[/tex].
To finalize the equation, you get [tex]y=\frac{-1}{3} x+4[/tex].

Find the area of each triangle. Round your answers to the nearest tenth. Show all your work
Answer:
1st question: 30
2nd question:78
Step-by-step explanation:
use the formula [tex]A=\frac{ab}{2} sin(y)[/tex]]
Where A is the area, a and b are the two given lengths and y is the given angle.
So,
a=9
b=7
y=73
Plugging those values in, we get:
[tex]A=(\frac{9*7}{2})Sin73\\=31.5(Sin73)\\=30.1\\=30 (rounded)[/tex]
For the 2nd question, we use the same formula, only this time
a=13
b=14
y=59
so,
[tex]A=\frac{13*14}{2} sin(59)\\A=91*Sin(59)\\A=78[/tex]

I have a bag of marbles, where each marble is pink or yellow. The ratio of pink marbles to yellow marbles is 3:5 If there are total of 72 marbles in the bag, how many are pink?
Answer:
i think its 27.
Step-by-step explanation:
Let the number of pink marbles = p
Let the number of yellow marbles = y
The ratio of pink marbles to yellow marbles is 3:5 . This means...
the number of pink marbles / the number of yellow marbles = 3 / 5
p / y = 3 / 5
There are a total of 72 marbles in the bag. So...
the number of pink marbles + the number of yellow marbles = 72
p + y = 72
y = 72 - p
Now we can use this value of y in the first equation and solve for p .
p / (72 - p) = 3 / 5
Multiply both sides of the equation by 5 .
5p / (72 - p) = 3
Multiply both sides by (72 - p)
5p = 3(72 - p)
5p = 216 - 3p
Add 3p to both sides.
8p = 216
Divide both sides by 8 .
p = 27
the number of pink marbles = 27
